The parties' stipulated facts are incorporated in this opinion by reference and are found accordingly. At the time of filing the petition, petitioner resided in New York.During the years in issue petitioner was a train operator with the Metropolitan Transportation Authority of New York City, where he typically worked 8 hours per day and 40 hours per week. Petitioner's commute to work was approximately 1 hour and 20 minutes.During the years in issue petitioner also engaged in various activities under an unincorporated venture that he named "Right Connections". Petitioner's activities, each of which he contends should qualify as a trade or business for Federal income tax purposes, included: (1) planning,2014 Tax Ct. Memo LEXIS 120">*122  and accompanying models on, overnight trips to a clothing-optional beach for suntanning; (2) selling comic books, baseball cards, and other paraphernalia; (3) creating and publishing a book of restaurant reviews; (4) trading stocks on the Internet; and (5) consulting.*122  On January 20, 2009, respondent received petitioner's Form 1040, U.S. Individual Income Tax Return (tax return), for petitioner's 2007 tax year. Petitioner timely filed tax returns for his 2008 and 2009 tax years. On each of his 2007, 2008, and 2009 tax returns petitioner reported on Schedule C the following expenses that petitioner claims are related to the various activities he pursued under Right Connections:Schedule C expense200720082009Wages$7,235$7,600$9,316Meals & entertainment2,7003,100—Travel4,3005,6006,285Repairs & maintenance1,6502,9004,258Office1,8502,8006,325Legal & professional12,00014,00019,755Advertising10,50013,10017,800Cost of goods sold2,1003,0503,300Total42,33552,15067,039Petitioner also claimed a $3,000 capital loss carryforward on Schedule D of each of his 2007, 2008, and 2009 tax returns. On those tax returns petitioner listed a post office box in New York (New York P.O. box) as his address.*123  On2014 Tax Ct. Memo LEXIS 120">*123  November 3, 2011, respondent issued petitioner a notice of deficiency for his 2007, 2008, and 2009 tax years, determining the aforementioned income tax deficiencies, accuracy-related penalties, and addition to tax. On January 9, 2012, petitioner filed a petition with this Court challenging respondent's determinations. On the petition, petitioner listed the New York P.O. Box as his address.OPINIONI. Burden of ProofGenerally, the Commissioner's determination of a deficiency is presumed correct, and the taxpayer has the burden of proving it incorrect. Rule 142(a); Welch v. Helvering, 290 U.S. 111">290 U.S. 111, 290 U.S. 111">115, 54 S. Ct. 8">54 S. Ct. 8, 78 L. Ed. 212">78 L. Ed. 212, 1933-2 C.B. 112 (1933). Section 7491(a)(1) provides an exception that shifts the burden of proof to the Commissioner as to any factual issue relevant to a taxpayer's liability for tax if: (1) the taxpayer introduces credible evidence with respect to that issue and (2) the taxpayer satisfies certain other conditions, including substantiation of any item and cooperation with the Government's requests for witnesses, documents, other information, and meetings. Sec. 7491(a)(2); see alsoRule 142(a)(2). The taxpayer bears the burden of *124  proving that the taxpayer has met the requirements of section 7491(a). Rolfs v. Commissioner, 135 T.C. 471">135 T.C. 471, 135 T.C. 471">483 (2010), aff'd, 668 F.3d 888">668 F.3d 888 (7th Cir. 2012).Petitioner did not argue that the burden should shift, and he failed to comply with the substantiation and cooperation2014 Tax Ct. Memo LEXIS 120">*124  requirements. Accordingly, the burden of proof remains on petitioner.3II. JurisdictionIn his petition, petitioner claims that he did not receive a notice of deficiency and contends that the case should be dismissed, presumably for lack of jurisdiction pursuant to section 6213(a). Petitioner's contention is without merit.A valid notice of deficiency and a timely petition are essential to this Court's jurisdiction in a deficiency case, and any case in which one or the other is not present must be dismissed. Rule 13(a), (c); Monge v. Commissioner, 93 T.C. 22">93 T.C. 22, 93 T.C. 22">27 (1989)*125 ; Pyo v. Commissioner, 83 T.C. 626">83 T.C. 626, 83 T.C. 626">632 (1984). A notice of deficiency is valid for purposes of section 6212(a) and section 6213(a), regardless of actual receipt by the taxpayer, if it is mailed to the taxpayer's last2014 Tax Ct. Memo LEXIS 120">*125  known address. Sec. 6212(b)(1); see Yusko v. Commissioner, 89 T.C. 806">89 T.C. 806, 89 T.C. 806">810 (1987); King v. Commissioner, 88 T.C. 1042">88 T.C. 1042, 88 T.C. 1042">1047(1987), aff'd, 857 F.2d 676">857 F.2d 676 (9th Cir. 1988); Frieling v. Commissioner, 81 T.C. 42">81 T.C. 42, 81 T.C. 42">52 (1983). The term "last known address" is well defined in the tax law. A taxpayer's last known address is the address that appears on the taxpayer's most recently filed and properly processed Federal tax return unless the IRS is given clear and concise notification of a different address. Sec. 301.6212-2(a), Proced. & Admin. Regs.Respondent mailed the notice of deficiency to petitioner's New York P.O. box, which was the same address that petitioner gave on each of his 2007, 2008, and 2009 tax returns, as well as on his petition. Petitioner does not contend that he gave respondent clear and concise notification of a different address. See id. Accordingly, we conclude that petitioner's New York P.O. box was his last known address pursuant to section 6212 and that respondent mailed the notice of *126  deficiency to petitioner's last known address.42014 Tax Ct. Memo LEXIS 120">*126 See id. Consequently, we decline to dismiss the instant case for lack of jurisdiction.III. Schedule C ExpensesOn Schedules C of his 2007, 2008, and 2009 tax returns petitioner claimed deductions pursuant to section 162 for various expenses relating to his activities pursued through Right Connections. Section 162(a) permits a taxpayer to deduct the ordinary and necessary expenses paid or incurred during the taxable year in carrying on a trade or business. See Commissioner v. Lincoln Sav. & Loan Ass'n, 403 U.S. 345">403 U.S. 345, 403 U.S. 345">352, 91 S. Ct. 1893">91 S. Ct. 1893, 29 L. Ed. 2d 519">29 L. Ed. 2d 519 (1971). In order for a taxpayer "to be engaged in a trade or business, the taxpayer must be involved in the activity with continuity and regularity and * * * the taxpayer's primary purpose for engaging in the activity must be for income or profit." Commissioner v. Groetzinger, 480 U.S. 23">480 U.S. 23, 480 U.S. 23">35, 107 S. Ct. 980">107 S. Ct. 980, 94 L. Ed. 2d 25">94 L. Ed. 2d 25 (1987)*127  . An expense is ordinary if it is normal, usual, or customary within a particular trade, business, or industry or arises2014 Tax Ct. Memo LEXIS 120">*127  from a transaction "of common or frequent occurrence in the type of business involved." Deputy v. Du Pont, 308 U.S. 488">308 U.S. 488, 308 U.S. 488">495, 60 S. Ct. 363">60 S. Ct. 363, 84 L. Ed. 416">84 L. Ed. 416, 1940-1 C.B. 118 (1940). An expense is necessary if it is appropriate and helpful for the development of the business. See Commissioner v. Lincoln Sav. & Loan Ass'n, 403 U.S. 345">403 U.S. at 353; Commissioner v. Heininger, 320 U.S. 467">320 U.S. 467, 320 U.S. 467">471, 64 S. Ct. 249">64 S. Ct. 249, 88 L. Ed. 171">88 L. Ed. 171, 1944 C.B. 484">1944 C.B. 484 (1943). Section 262(a) disallows deductions for personal, living, or family expenses. See alsosec. 1.162-17(a), Income Tax Regs.5Deductions are a matter of legislative grace, and the taxpayer bears the burden of proving that he is entitled to any claimed deductions. INDOPCO, Inc. v. Commissioner, 503 U.S. 79">503 U.S. 79, 503 U.S. 79">84, 112 S. Ct. 1039">112 S. Ct. 1039, 117 L. Ed. 2d 226">117 L. Ed. 2d 226 (1992). This includes the burden of substantiation. Sec. 6001; Hradesky v. Commissioner, 65 T.C. 87">65 T.C. 87, 65 T.C. 87">89 (1975), aff'd per curiam, 540 F.2d 821">540 F.2d 821 (5th Cir. 1976); Martell v. Commissioner, T.C. Memo. 2013-115, at *24; sec. 1.6001-1(a), (e), Income Tax Regs. Taxpayers must maintain records relating to their income and expenses and must prove their entitlement to all claimed deductions, credits, and expenses in controversy. See*128 sec. 6001; Rule 142(a); INDOPCO, Inc. v. Commissioner, 503 U.S. 79">503 U.S. at 84; Welch v. Helvering, 290 U.S. 111">290 U.S. at 115. Adequate substantiation must establish the nature, amount, and purpose of a claimed deduction. Higbee v. Comm'r, 116 T.C. 438">116 T.C. 438, 116 T.C. 438">440 (2001); see also Hradesky v. Commissioner, 65 T.C. 87">65 T.C. 89-90. The taxpayer must produce such records upon the Secretary's request. Sec. 7602(a); see alsosec. 1.6001-1(e), Income Tax Regs.An expense may be deductible even where the taxpayer is unable to fully substantiate it. Christine v. Commissioner, T.C. Memo. 2010-144, 2010 WL 2640125">2010 WL 2640125, at *2010 WL 2640125">2, aff'd,2014 Tax Ct. Memo LEXIS 120">*128 475 Fed. Appx. 259">475 Fed. Appx. 259 (9th Cir. 2012). The regulations provide that "[w]here records are incomplete or documentary proof is unavailable, it may be possible to establish the amount of the expenditures by approximations based upon reliable secondary sources of information and collateral evidence." Sec. 1.162-17(d)(3), Income Tax Regs. However, there must be sufficient evidence in the record to provide a basis upon which an estimate may be made and to permit us to conclude that a deductible expense, rather than a nondeductible personal expense, was incurred in at least the amount allowed. Cohan v. Comm'r, 39 F.2d 540">39 F.2d 540, 39 F.2d 540">543-544 (2d Cir. 1930); Vanicek v. Commissioner, 85 T.C. 731">85 T.C. 731, 85 T.C. 731">742-743 (1985); Christine v. Commissioner, T.C. Memo 2010-144, 2010 WL 2640125">2010 WL 2640125, at *2010 WL 2640125">2. In these instances, the Court is permitted to make as close an approximation *129  of the allowable expense as it can, bearing heavily against the taxpayer whose inexactitude is of his or her own making. Cohan v. Commissioner, 39 F.2d 540">39 F.2d at 543-544. In making such an approximation,due consideration will be given to the reasonableness of the stated expenditures for the claimed purposes in relation to the taxpayer's circumstances (such as his income and the nature of his occupation), to the reliability and accuracy of records in connection with other items more readily lending themselves to detailed record-keeping, and to all of the facts and circumstances in the particular case.Sec. 1.162-17(d)(3), Income Tax Regs.In deciding whether a taxpayer has satisfied2014 Tax Ct. Memo LEXIS 120">*129  his or her burden of substantiating a deduction, we are not required to accept the taxpayer's self-serving, undocumented testimony. Niedringhaus v. Commissioner, 99 T.C. 202">99 T.C. 202, 99 T.C. 202">219-220 (1992); Tokarski v. Commissioner, 87 T.C. 74">87 T.C. 74, 87 T.C. 74">77 (1986).However, certain expenses may not be estimated because of the strict substantiation requirements of section 274(d). Sanford v. Commissioner, 50 T.C. 823">50 T.C. 823, 50 T.C. 823">827-828 (1968), aff'd per curiam, 412 F.2d 201">412 F.2d 201 (2d Cir. 1969). Travel expenses, meals and entertainment, and expenses relating to certain listed property are subject to the specific and more stringent substantiation requirements of section 274. Seesec. 274(d). To deduct such expenses, the taxpayer must substantiate by adequate records or sufficient evidence to corroborate the *130  taxpayer's own testimony: (1) the amount of the expense; (2) the time and place of the travel or meal expenditure; (3) the business purpose of the expense; and (4) in the case of meals and entertainment, the business relationship between the taxpayer and the persons being entertained. Id. Generally, deductions for expenses subject to the strict substantiation requirements of section 274(d) must be disallowed in full unless the taxpayer satisfies every element of those requirements. Sanford v. Commissioner, 50 T.C. 823">50 T.C. 827-828; sec. 1.274-5T(a), Temporary Income Tax Regs., 50 Fed. Reg. 46014 (Nov. 6, 1985).To substantiate by adequate records, the taxpayer must provide (1) an account book, log, or similar record and (2) documentary evidence, which together are sufficient2014 Tax Ct. Memo LEXIS 120">*130  to establish each element of an expenditure. Sec. 1.274-5T(c)(2)(i), Temporary Income Tax Regs., 50 Fed. Reg. 46017 (Nov. 6, 1985). Documentary evidence includes receipts, paid bills, or similar evidence. Sec. 1.274-5(c)(2)(iii), Income Tax Regs. As we have stated, a contemporaneous log is not required, but corroborative evidence used to support a taxpayer's reconstruction of the expenditure "'must have a high degree of probative value to elevate such statement'" to the level of credibility of a contemporaneous record. Larson v. Commissioner, T.C. Memo. 2008-187, 2008 WL 2986387">2008 WL 2986387, at *2008 WL 2986387">4 (quoting section *131 1.274-5T(c)(1), Temporary Income Tax Regs., 50 Fed. Reg. 46016 (Nov. 6, 1985)).To substantiate by sufficient evidence corroborating the taxpayer's own statement, the taxpayer must establish each element by his or her own statement and by documentary evidence or other direct evidence. Sec. 1.274-5T(c)(3)(i), Temporary Income Tax Regs., 50 Fed. Reg. 46020 (Nov. 6, 1985). To establish the business purpose of an expenditure, however, a taxpayer may corroborate his or her own statement with circumstantial evidence. Id.Petitioner claims various expense deductions on Schedules C attached to his 2007, 2008, and 2009 tax returns. We review the deductibility of each of petitioner's expenses in turn.A. WagesPetitioner claimed $7,235, $7,600, and $9,316 of wage expense deductions on Schedules C attached to his 2007, 2008, and 2009 tax returns, respectively. Petitioner has not offered any written substantiation, testimony, or2014 Tax Ct. Memo LEXIS 120">*131  other evidence in support of these expenses. Consequently, we conclude that petitioner has failed to carry his burden of proving that he is entitled to the claimed deductions for wage expenses.*132  B. MealsPetitioner claimed deductions for $2,700 and $3,100 of expenses related to meals on Schedules C attached to his 2007 and 2008 tax returns, respectively. Petitioner contends that he incurred these expenses while attempting to compile a book of New York restaurant reviews; petitioner alleges that he paid for meals for reviewers who would then review the dining experience. To substantiate these expenses, petitioner submitted an unsigned sample confidentiality agreement that he contends he used for contracts with the reviewers. The sample agreement does not substantiate the amount, time, or place of any meals expenses. Petitioner also submitted self-prepared spreadsheets listing total amounts spent at each restaurant for 2007 and 2008 and sample reviews submitted by the restaurant reviewers. None of the submitted documents indicates, on its own or when viewed with the others, when it was created or provides enough information for us to determine precisely what was purchased or when it was2014 Tax Ct. Memo LEXIS 120">*132  purchased. Moreover, we question the credibility of the submitted documents because petitioner himself created the spreadsheets and the reviewers failed to sign or otherwise authenticate the submitted reviews. Accordingly, we do not accept any of the documents as credible evidence of the underlying expenses and, therefore, petitioner has not *133  carried his burden of proving that he is entitled to the claimed deductions for these expenses.C. TravelPetitioner claimed $4,300, $5,600, and $6,285 of travel expense deductions on Schedules C attached to his 2007, 2008, and 2009 tax returns, respectively. Travel expenses may not be estimated and are subject to the specific and more stringent substantiation requirements of section 274. Seesec. 274(d); Sanford v. Commissioner, 50 T.C. 823">50 T.C. 827-828. Petitioner did not submit any substantiation in support of the $6,285 of travel expense deductions claimed on his 2009 tax return. Regarding his claimed 2007 and 2008 travel expenses, petitioner submitted (1) self-prepared spreadsheets indicating the cost of ferry tickets and overnight tent lodging for his travels related to the suntanning activities of Right Connections and (2) handwritten, generic receipts documenting the cost of tent lodging, but not ferry tickets,2014 Tax Ct. Memo LEXIS 120">*133  for his suntanning activities. As to the submitted documents, we question their credibility because petitioner himself created the spreadsheets and the submitted receipts were drafted on generic, rather than customized, receipt paper and were not authenticated.6 Accordingly, we do not accept any of the *134  documents as credible evidence of the underlying travel expenses. Consequently, petitioner has failed to carry his burden of proving that he is entitled to the claimed deductions for travel expenses.D. Repairs2014 Tax Ct. Memo LEXIS 120">*134  and MaintenancePetitioner claimed $1,650, $2,900, and $4,258 of repair and maintenance expense deductions on Schedules C attached to his 2007, 2008, and 2009 tax returns, respectively. Petitioner has not offered any written substantiation, testimony, or other evidence in support of his 2009 repair and maintenance expenses. Regarding his 2007 and 2008 repair and maintenance expenses, petitioner submitted two self-created job invoices for computer repair and reconstruction. Petitioner admits that he lost the original receipts and submitted recreated job invoices. The recreated job invoices were not contemporaneous with any of the work and were signed by a former employee of the company that provided the computer services, but that former employee no longer has any *135  authority to bind the company. Additionally, the former employee did not appear at trial to authenticate the recreated job invoices. Accordingly, we do not accept the recreated job invoices as credible substantiation of the underlying expenses. Moreover, petitioner did not testify as to how the repair expenses were related to his alleged business. Consequently, we conclude that petitioner has failed to carry his burden of2014 Tax Ct. Memo LEXIS 120">*135  proving that he is entitled to the claimed deductions for repair and maintenance expenses.E. OfficePetitioner claimed $1,850, $2,800, and $6,325 of office expense deductions on Schedules C attached to his 2007, 2008, and 2009 tax returns, respectively. Petitioner did not offer any written substantiation, testimony, or other evidence in support of those expenses and, therefore, has failed to carry his burden of proving that he is entitled to the claimed deductions.F. Legal and ProfessionalPetitioner claimed $12,000, $14,000, and $19,755 of legal and professional expense deductions on Schedules C attached to his 2007, 2008, and 2009 tax returns, respectively. Petitioner did not offer any written substantiation, testimony, or other evidence in support of his 2009 legal and professional expenses. Regarding his claimed 2007 and 2008 legal expenses, petitioner *136  submitted a (1) self-created notice of legal expenses listing costs for court fees and administration, costs to prepare legal documents, and costs of labor for petitioner's pro se representation, and (2) two self-created promissory notes in which petitioner signed as both the payor, acting on behalf of Right Connections, and the payee.2014 Tax Ct. Memo LEXIS 120">*136  The notice of legal expenses does not separately document each specific court fee or document produced. Petitioner admits that his substantiation and recollection of the legal expenses "is a little murky" and that he "probably didn't break down the expense properly." Accordingly, we do not accept the notice of legal expenses and the promissory notes as credible substantiation of the underlying legal expenses. Consequently, we conclude that petitioner has failed to carry his burden of proving that he is entitled to the claimed deductions for legal and professional expenses.G. AdvertisingPetitioner claimed $10,500, $13,100, and $17,800 of advertising expense deductions on Schedules C attached to his 2007, 2008, and 2009 tax returns, respectively. Petitioner did not offer any written substantiation, testimony, or other evidence in support of his 2009 advertising expenses. Regarding his claimed 2007 and 2008 advertising expenses, petitioner submitted two job invoices, dated March 15, 2007, and April 17, 2008, for various advertising *137  materials and distribution services. However, both documents lack invoice numbers and appear to have been created by petitioner. Moreover, the alleged invoices2014 Tax Ct. Memo LEXIS 120">*137  were signed only by petitioner and were not authenticated by a representative of the advertising company that provided the alleged services. Accordingly, we do not accept either invoice as credible evidence of the underlying advertising expenses. Consequently, we conclude that petitioner has failed to carry his burden of proving that he is entitled to the claimed deductions for advertising expenses.H. Cost of Goods SoldPetitioner reported $2,100, $3,050, and $3,300 of costs of goods sold on Schedules C attached to his 2007, 2008, and 2009 tax returns, respectively. Petitioner did not offer any written substantiation, testimony, or other evidence in support of his 2009 cost of goods sold. Regarding his claimed 2007 and 2008 costs of goods sold, petitioner submitted self-created spreadsheets of purchases that he made through PayPal.7 Petitioner's submissions are not official PayPal records, and they do not indicate account numbers, items ordered or sold, or even seller or buyer information beyond a PayPal identification name. In fact, some of *138  the sellers or buyers, such as the ones named "the finest fragrances", "SHOES FOR AUCTION", and "Teahouse Treasures", cause us to question whether2014 Tax Ct. Memo LEXIS 120">*138  the transactions were even related to his alleged business activities performed under the trade name Right Connections. Moreover, in the spreadsheets petitioner seems to have haphazardly compiled both sales and purchases, and we are unable to distinguish the ones from the others. We do not accept petitioner's spreadsheets as credible evidence of costs of goods sold. Accordingly, we conclude that petitioner has failed to carry his burden of proving that he is entitled to the claimed costs of goods sold.Upon the basis of the foregoing, we sustain respondent's determinations in the notice of deficiency that petitioner is not entitled to deduct any expenses pursuant to section 162 on his 2007, 2008, or 2009 tax return.IV. Schedule D ExpensesSection 165(a) generally permits deductions for losses sustained during the taxable year and not compensated for by insurance or otherwise. However, capital losses on the sale or exchange of capital assets are limited to the extent allowed under sections 1211 and 1212. Sec. 165(f). Subject to the limitations of section 1211, taxpayers can carry forward their capital losses to succeeding taxable2014 Tax Ct. Memo LEXIS 120">*139  years. Sec. 1212(b). Pursuant to section 1211, noncorporate taxpayers are permitted to *139  deduct losses on the sale or exchange of capital assets to the extent of the gain from such sales or exchanges, plus the lower of: (1) $3,000 ($1,500 in the case of a married individual filing separately) or (2) the excess of such losses over such gains. Sec. 1211(b). Section 1212(b)(1)(B) provides that the excess of the net long-term capital loss over the net short-term capital gain is to be treated as a long-term capital loss for the succeeding taxable year.To be entitled to a deduction under section 165(a), a taxpayer is required to keep records to establish the loss. Sec. 6001. If a deduction is carried forward from one year to another, the taxpayer must keep records to substantiate the amount. Sec. 1.6001-1(e), Income Tax Regs. To substantiate a capital loss carryforward, the taxpayer must show: that a loss was incurred; when the loss was incurred; that the taxpayer is entitled to deduct the loss; whether the loss is capital or noncapital, or business or personal; and the amount of capital gain during the intervening years.

Memo. 1993-436, 1993 WL 369137">1993 WL 369137, at *1993 WL 369137">3-*4.Petitioner claimed a $3,000 capital loss carryforward on Schedule D of each of his 2007, 2008, and 2009 tax returns. However, petitioner (1) offered no *140  credible evidence to substantiate2014 Tax Ct. Memo LEXIS 120">*140  the capital loss carryforwards, (2) did not address the capital loss carryforwards in his petition, in his pretrial memorandum, or during trial, and, (3) as we previously noted, failed to submit a posttrial brief. We treat the issue as conceded by petitioner. SeeRule 149(b). In any event, we conclude that petitioner has failed to carry his burden of substantiating the claimed capital loss carryforwards. On the basis of the foregoing, we sustain respondent's determinations in the notice of deficiency that petitioner is not entitled to deduct any capital loss carryforward on his 2007, 2008, or 2009 tax return.V. Additions to TaxFor petitioner's 2007 tax year, respondent determined that petitioner is liable for the addition to tax pursuant to section 6651(a)(1) for his failure to timely file a Federal income tax return.Section 6651(a)(1) provides that, in the case of a failure to file a tax return on the date prescribed for filing (including any extension of time for filing), there shall be added to the tax required to be shown on the return an amount equal to 5% of that tax for each month or fraction thereof that the failure to file continues, not exceeding 25% in the aggregate. The addition to tax is mandatory unless it is shown2014 Tax Ct. Memo LEXIS 120">*141  that the failure to file is due to reasonable cause and not willful neglect. Sec. 6651(a)(1); Estate of Cavenaugh v. Commissioner, 100 T.C. 407">100 T.C. 407, 100 T.C. 407">426 (1993), *141 aff'd in part, rev'd in part on other grounds, 51 F.3d 597">51 F.3d 597 (5th Cir. 1995). Reasonable cause for delay is established where a taxpayer is unable to file despite the exercise of ordinary business care and prudence. Bassett v. Commissioner, 67 F.3d 29">67 F.3d 29, 67 F.3d 29">31 (2d Cir. 1995), aff'g100 T.C. 650">100 T.C. 650 (1993); sec. 301.6651-1(c)(1), Proced. & Admin. Regs. "Willful neglect" has been defined as a "conscious, intentional failure or reckless indifference." United States v. Boyle, 469 U.S. 241">469 U.S. 241, 469 U.S. 241">245, 105 S. Ct. 687">105 S. Ct. 687, 83 L. Ed. 2d 622">83 L. Ed. 2d 622 (1985). Whether a failure to file timely is due to reasonable cause and not willful neglect is a question of fact. 469 U.S. 241">Id. at 249 n.8; Crocker v. Commissioner, 92 T.C. 899">92 T.C. 899, 92 T.C. 899">913 (1989).In the notice of deficiency, respondent determined that petitioner's 2007 tax return was received by the Internal Revenue Service on January 20, 2009, more than 11 months after the filing deadline of April 15, 2008, and determined that petitioner was liable for an addition to tax of $1,699 for petitioner's 2007 tax year. Petitioner does not contend or offer evidence to prove that the return was timely filed, that respondent incorrectly computed the addition to tax, or that his failure to file timely was due to reasonable cause. Indeed, petitioner does not address respondent's proposed addition to tax in his petition, in his pretrial memorandum, or during trial, and, as we previously2014 Tax Ct. Memo LEXIS 120">*142  noted, petitioner failed to submit a posttrial brief. We treat the issue as conceded by petitioner. SeeRule 149(b). *142  Accordingly, we sustain respondent's determination that petitioner is liable for an addition to tax pursuant to section 6651(a)(1) for his 2007 tax year.VI. Accuracy-Related PenaltyFor each of the years in issue, respondent determined that petitioner is liable for an accuracy-related penalty pursuant to section 6662(a).Section 6662(a) imposes an accuracy-related penalty of 20% of any underpayment that is attributable to causes specified in subsection (b). Subsection (b) applies the penalty to any underpayment attributable to, inter alia, a "substantial understatement" of income tax. An "understatement" is the excess of the amount of tax required to be shown on the return over the amount of tax that is actually shown on the return, reduced by any rebate. Sec. 6662(d)(2)(A). A "substantial understatement" of income tax exists if the amount of the understatement for the taxable year exceeds the greater of (1) 10% of the tax required to be shown on the return or (2) $5,000. Sec. 6662(d)(1)(A).Generally, the Commissioner bears the burden of production with respect to any penalty, including the accuracy-related penalty. Sec. 7491(c); Higbee v. Commissioner, 116 T.C. 438">116 T.C. 446. However, petitioner did not address respondent's2014 Tax Ct. Memo LEXIS 120">*143  proposed accuracy-related penalties in his petition, in his pretrial memorandum, or during trial, and, as we previously noted, petitioner failed to submit a posttrial *143  brief. SeeRule 149(b). Accordingly, we treat the issue as conceded by petitioner and we sustain respondent's determination that petitioner is liable for the accuracy-related penalties pursuant to section 6662(a) for the years in issue.VII. ConclusionIn sum, we conclude that (1) we have jurisdiction pursuant to section 6213(a) to consider the instant case; (2) petitioner is not entitled to deduct Schedule C expenses of $42,335, $52,150, and $67,039 for his 2007, 2008, and 2009 tax years, respectively; (3) petitioner is not entitled to deduct a Schedule D capital loss carryforward of $3,000 for any of the years in issue; (4) petitioner is liable for an addition to tax pursuant to section 6651(a)(1) for his 2007 tax year; and (5) petitioner is liable for an accuracy-related penalty pursuant to section 6662(a) for each of the years in issue. Consequently, we sustain respondent's determinations that petitioner is liable for income tax deficiencies, an addition to tax, and accuracy-related penalties.In reaching these holdings, we have considered all the parties' arguments, and, to the extent not2014 Tax Ct. Memo LEXIS 120">*144  addressed herein, we conclude that they are moot, irrelevant, or without merit.*144  To reflect the foregoing,Decision will be entered for respondent.Footnotes1. Unless otherwise indicated, section references are to the Internal Revenue Code of 1986, as amended (Code) and in effect for the years in issue, and Rule references are to the Tax Court Rules of Practice and Procedure. We round all monetary amounts to the nearest dollar.2. The remaining adjustments set forth in the notice of deficiency are computational and will be resolved by our holdings on the aforementioned issues. Consequently, we do not specifically address the remaining adjustments in this opinion.↩3. We note that petitioner failed to comply with the Court's orders to file a posttrial brief. When a party fails to file a brief altogether, the failure has been held by this Court to justify the dismissal of all issues as to which the nonfiling party has the burden of proof. SeeRule 123; Stringer v. Commissioner, 84 T.C. 693">84 T.C. 693 (1985), aff'd without published opinion, 789 F.2d 917">789 F.2d 917 (4th Cir. 1986). While we decline to enter a default judgment against petitioner for failure to file a brief, we view his failure as an indication of his tenuous position with regard to the issues in question. See McGee v. Commissioner, T.C. Memo. 2000-308, 2000 WL 1434240">2000 WL 1434240, at *2000 WL 1434240">6↩.4. We note that respondent has the burden of proving that the notice of deficiency was properly mailed. See August v. Commissioner, 54 T.C. 1535">54 T.C. 1535, 54 T.C. 1535">1536 (1970). Sec. 6212(a) expressly authorizes the Commissioner, after determining a deficiency, to send a notice of deficiency to the taxpayer by certified or registered mail. Respondent presented the mailed notice of deficiency and its certified mail number. Petitioner does not contend that there was any mailing impropriety. Moreover, petitioner did not stipulate facts, present admissible evidence, or otherwise contend at trial or on brief that he did not receive a notice of deficiency, much less that there was any mailing impropriety. Accordingly, we conclude that petitioner has conceded that the notice of deficiency was properly mailed. SeeRule 149(b); Cadwell v. Commissioner, 136 T.C. 38">136 T.C. 38, 136 T.C. 38">48-49 (2011), aff'd, 483 Fed. Appx. 847">483 Fed. Appx. 847↩ (4th Cir. 2012).5. For purposes of the instant opinion, we assume, without deciding, that petitioner's reported Schedule C expenses on his 2007, 2008, and 2009 tax returns, insofar as they are properly substantiated, are trade or business expenses pursuant to sec. 162↩.6. Attached to some, but not all, of the documents petitioner submitted as substantiation are notarized statements affirming that the "aforementioned Statements, Ledgers, Receipts, and/or Diaries are true and genuine." However, petitioner's notarized statements only confirm that petitioner himself signed the notarized statements. They do not authenticate any of the underlying documents he created and submitted as substantiation for his expenses. Instead, we question the contemporaneity and accuracy of petitioner's self-created documents because the attached notarized statements were not notarized until July 6, 2010, more than a year after the expenses were claimed to have been incurred.↩7.
