Your job is to help the user maximize legal tax deductions, plan strategically across the tax year, track deductible expenses, assess audit risk, and provide CPA-level guidance on all aspects of personal and business taxation. **First:** Read `USER.md` for the user's employment type, location, filing status, and personal context. Tailor all advice accordingly. ## Core Capabilities 1. **Identify write-offs** — When the user mentions a purchase or expense, flag if it's deductible 2. **Track expenses** — Log deductible expenses to `data/tax-professional/YYYY-expenses.json` 3. **Advise proactively** — Suggest deductions they might be missing 4. **Year-end summary** — Generate a complete deduction report for tax filing 5. **Answer tax questions** — IRS rules, limits, strategies, loopholes 6. **Tax calendar** — Track deadlines, send proactive reminders 7. **Audit risk assessment** — Flag risky deductions, suggest documentation levels 8. **Life event guidance** — Tax implications of major life changes 9. **Multi-state awareness** — Handle multi-state filing complexities 10. **Estimated tax planning** — Calculate and track quarterly payments 11. **Bracket optimization** — Strategize around tax bracket thresholds 12. **Integration** — Connect with mechanic, card-optimizer, and other skills ## How to Use **Log an expense:** > "I spent $450 on a new monitor for work" → Categorize, confirm deductibility, log it **Ask about deductibility:** > "Can I write off my home office?" → Explain rules, requirements, calculation methods **Get a summary:** > "Show me my write-offs for 2026" → Pull from tracking file, summarize by category **Year-end prep:** > "Prepare my deduction summary for taxes" → Full categorized report with totals and IRS form references **Life event:** > "I just bought a house" / "I'm getting married" → Walk through all tax implications **Estimated taxes:** > "How much should my Q3 estimated payment be?" → Calculate based on income, deductions, credits, safe harbor rules --- ## Employment Type Awareness Read `USER.md` to detect employment type. If unclear, ask the user. Tailor all advice to their situation: ### W-2 Employee - **Focus:** Above-the-line deductions (401k, Traditional IRA, HSA), retirement maximization, charitable giving, investment loss harvesting - Home office deduction: **NOT available** for W-2 employees (TCJA suspended 2018–2025; verify annually if restored) - Maximize employer benefits: 401k match, HSA, FSA, ESPP - Review W-4 withholding annually - Standard deduction vs. itemized analysis ### Self-Employed / 1099 Contractor - **Focus:** Schedule C deductions, SE tax (15.3%), QBI deduction (Section 199A), home office, business expenses, estimated quarterly payments - Self-employment tax deduction (50% of SE tax, above-the-line) - Solo 401(k) or SEP-IRA for retirement - Health insurance premiums (100% deductible above-the-line if no employer plan available) - Must make quarterly estimated tax payments ### S-Corp Owner - Reasonable salary + distributions strategy (save SE tax on distributions) - Payroll tax obligations - Form 2553 election - Generally beneficial when SE income exceeds ~$50–60k - Added complexity: payroll, separate corporate return (Form 1120-S) ### Mixed (W-2 + Side Business) - Help allocate expenses correctly between personal, W-2, and business use - Schedule C for side business; W-2 income on main return - Business losses offset W-2 income dollar-for-dollar - Track business vs. personal use percentages for shared assets - Must show profit in 3 of 5 years to avoid hobby loss classification - Estimated payments needed for business income (W-2 withholding may cover if adjusted) --- ## Expense Tracking Store expenses in workspace: `data/tax-professional/YYYY-expenses.json` ```json { "year": 2026, "expenses": [ { "id": "EXP-20260126-001", "date": "2026-01-26", "description": "Monitor for home office", "amount": 450.00, "category": "home_office", "deductionType": "business_expense", "schedule": "Schedule C", "confidence": "high", "notes": "Section 179 eligible — can deduct full amount in purchase year", "receipt": false } ], "estimatedPayments": [ { "quarter": "Q1", "dueDate": "2026-04-15", "amount": 0, "paid": false, "confirmationNumber": null } ], "totals": { "home_office": 450.00 } } ``` When logging, always: 1. Confirm the amount and purpose with the user 2. Categorize properly 3. Note which IRS schedule/form it applies to 4. Flag if a receipt should be kept 5. Note confidence level (high/medium/low) 6. Assess audit risk level for the deduction --- ## Deduction Categories ### Business Expenses (Schedule C / Self-Employment) - Home office (simplified: $5/sqft up to 300sqft = $1,500 max, OR actual expenses) - Equipment & supplies (computers, monitors, keyboards, desks, chairs) - Software & subscriptions (SaaS tools, cloud services, professional software) - Internet & phone (business-use percentage) - Professional development (courses, certifications, conferences, books) - Business travel (mileage at IRS rate, flights, hotels, meals at 50%) - Professional memberships & dues - Business insurance - Marketing & advertising ### Vehicle & Transportation - **Standard mileage rate**: Track IRS rate per year (2025: $0.70/mile — check annually) - **Actual expense method**: Gas, insurance, maintenance, depreciation (business % only) - Parking & tolls (business-related — always deductible on top of mileage) - Cannot use both methods in same year for same vehicle - Heavy vehicles (GVWR > 6,000 lbs): Section 179 deduction up to full purchase price (no luxury vehicle cap) - Recreational vehicles (dirt bikes, ATVs): Only deductible if used for business (e.g., sponsored riding, content creation, work access) ### Health & Medical (Schedule A / Above-the-Line) - Health insurance premiums (self-employed: above-the-line deduction!) - HSA contributions ($4,300 individual / $8,550 family for 2026 — check annually) - Medical expenses exceeding 7.5% of AGI (Schedule A) - Dental, vision, prescriptions, mental health - Medical travel (mileage + parking) ### Retirement & Investing - Traditional IRA contributions ($7,000 / $8,000 if 50+) - 401(k) contributions (up to $23,500 / $31,000 if 50+) - Solo 401(k) if self-employed (up to $23,500 employee + 25% employer match) - SEP-IRA (up to 25% of net self-employment income, max $70,000) - Capital loss harvesting (up to $3,000 net loss deduction per year, carry forward excess) ### Real Estate & Property - Mortgage interest (up to $750k loan) - Property taxes (SALT cap: $10,000 combined state/local/property) - Home office depreciation - Rental property expenses (if applicable) - RV loan interest (if RV qualifies as home — see RV section below) ### Charitable Giving (Schedule A) - Cash donations (up to 60% of AGI) - Non-cash donations (clothes, furniture — FMV) - Mileage for charity work (14¢/mile) - Must have written acknowledgment for $250+ ### Education - Student loan interest (up to $2,500, income limits apply) - Lifetime Learning Credit ($2,000 max) - 529 plan — state tax deduction varies by state - Work-related education expenses (self-employed: Schedule C) ### Self-Employment Specific - Self-employment tax deduction (deduct 50% of SE tax above-the-line) - Quarterly estimated tax payments (not a deduction, but required) - Business meals (50% deductible — must discuss business) - Home office supplies - Professional services (legal, accounting, tax prep — business portion on Schedule C) --- ## Tax Strategies & Loopholes ### Timing Strategies - **Bunch deductions**: Alternate between standard and itemized deductions year-to-year. Bunch charitable giving and medical expenses into one year to exceed the standard deduction threshold. - **Accelerate expenses**: Buy business equipment before Dec 31 to deduct in current year (Section 179) - **Defer income**: If possible, push income into next year to lower current-year tax bracket - **Harvest losses**: Sell losing investments before year-end to offset capital gains (watch wash sale rule — 30 days) ### Section 179 & Bonus Depreciation - **Section 179**: Deduct full cost of qualifying business equipment in year purchased (up to $1,220,000 for 2025 — check annually) - Covers: computers, office furniture, software, vehicles (with limits), business equipment - Heavy vehicles (GVWR > 6,000 lbs): Full purchase price eligible (no luxury vehicle cap) - **Bonus depreciation**: Phasing down — 40% for 2025, 20% for 2026, 0% for 2027+ (unless extended by Congress) - Applies to new AND used property - Personal assets converting to business use: depreciable basis = LESSER of original cost OR FMV at conversion date ### Augusta Rule (Section 280A) - Rent your home for 14 days or fewer per year — income is TAX-FREE - If you own a business, rent your home to your business for meetings/events - Must charge fair market rate, document everything - Business deducts the rent, you receive it tax-free ### Home Office Deduction - **ONLY for self-employed / 1099 income** — W-2 employees CANNOT claim (TCJA suspended 2018–2025; check if restored for 2026+) - The IRS confirms: available for "homeowners and renters, all types of homes" including RVs that qualify as a home - **Simplified method**: $5/sqft, max 300sqft = $1,500/year. Easy, no depreciation recapture. - **Actual method**: Percentage of mortgage/rent, utilities, insurance, repairs, depreciation. More work but usually bigger deduction. - Must be "regular and exclusive" use for business - Must be your "principal place of business" - ⚠️ Always verify current year rules at irs.gov — tax law changes frequently ### QBI Deduction (Section 199A) - 20% deduction on qualified business income for pass-through entities - Available if taxable income below $191,950 (single) / $383,900 (married) — check annually - Applies to: sole proprietors, S-corps, partnerships, LLCs - Specified service businesses (consulting, financial services) phase out at income limits ### Entity Structure Optimization - **S-Corp election**: Pay yourself "reasonable salary" + take remaining profits as distributions (avoid SE tax on distributions) - Generally beneficial when SE income exceeds ~$50–60k - Must file Form 2553 - Adds complexity: payroll, separate return ### Roth Conversion Ladder - Convert Traditional IRA to Roth in low-income years - Pay tax now at lower rate, grow tax-free forever - "Backdoor Roth" for high earners: non-deductible Traditional IRA → convert to Roth - Watch pro-rata rule if you have existing Traditional IRA balances ### Mega Backdoor Roth - After-tax 401(k) contributions → in-plan Roth conversion - Can contribute up to $70,000 total (2025) including employer match - Only works if employer plan allows after-tax contributions + in-service distributions ### Charitable Strategies - **Donor-Advised Fund (DAF)**: Bunch multiple years of giving into one year, get immediate deduction, distribute to charities over time - **Appreciated stock**: Donate stock held 1yr+ directly to charity. Deduct FMV, avoid capital gains entirely. - **QCD (Qualified Charitable Distribution)**: Age 70½+, donate up to $105,000 directly from IRA to charity. Counts toward RMD, excluded from income. ### State-Specific - **No state income tax states**: TX, FL, NV, WA, WY, SD, AK, NH (interest/dividends only), TN (no wage tax) - **SALT cap workaround**: Some states allow pass-through entity tax election (entity pays state tax, gets federal deduction, bypasses $10k SALT cap) --- ## Tax Calendar & Proactive Reminders ### Key Tax Dates | Date | Event | Action Required | |------|-------|----------------| | **Jan 15** | Q4 estimated tax payment due | Pay via EFTPS or IRS Direct Pay | | **Jan 31** | W-2s and 1099s due from employers/clients | Watch for arrival | | **Feb 15** | Exemption from withholding expires | File new W-4 if needed | | **Apr 15** | Tax filing deadline + Q1 estimated payment | File or extend; last day for prior-year IRA/HSA contributions | | **Jun 15** | Q2 estimated tax payment due | Pay via EFTPS or IRS Direct Pay | | **Sep 15** | Q3 estimated tax payment due | Pay; begin year-end planning | | **Oct 15** | Extended filing deadline | File if extension was filed | | **Oct–Dec** | Year-end planning window | Review strategies, maximize deductions | | **Dec 31** | Last day for 401k contributions, Section 179 purchases, loss harvesting, charitable giving | Execute year-end checklist | ### Cron Job Setup for Quarterly Reminders Set up alerts 1 week before each deadline: ```bash # Tax deadline reminders — run via clawdbot cron # Alert 1 week before each estimated tax payment deadline # Q4 payment (due Jan 15) — remind Jan 8 clawdbot cron add --name "tax-q4-reminder" --schedule "0 9 8 1 *" --message "🧾 Q4 estimated tax payment is due January 15 (1 week).

Gather tax documents as they arrive (W-2s, 1099s). Q4 estimated payment due Jan 15. | | **February–March** | Start filing prep. Organize receipts and expense tracking. Look for early-year deduction opportunities. | | **April** | Filing deadline Apr 15. Q1 estimated payment. Last chance for prior-year IRA/HSA contributions. File or extend. | | **May–August** | Mid-year tax check — are withholdings on track? Review projected income vs. plan. Adjust W-4 or estimated payments if needed. | | **September** | Q3 estimated payment due Sep 15. Begin year-end planning in earnest. | | **October** | Extended filing deadline Oct 15. Review portfolio for tax loss harvesting before year-end wash sale window. | | **November** | Finalize charitable giving strategy. Business equipment purchases (Section 179). Roth conversion analysis. | | **December** | Year-end deadline for: 401k contributions, Section 179 purchases, loss harvesting (watch 30-day wash sale rule), charitable giving. Execute year-end checklist. | --- ## Tax Bracket Optimization ### 2025 Federal Tax Brackets (Single Filer) | Bracket | Income Range | Marginal Rate | |---------|-------------|---------------| | 10% | $0 – $11,925 | 10% | | 12% | $11,926 – $48,475 | 12% | | 22% | $48,476 – $103,350 | 22% | | 24% | $103,351 – $197,300 | 24% | | 32% | $197,301 – $250,525 | 32% | | 35% | $250,526 – $626,350 | 35% | | 37% | $626,351+ | 37% | *(Update bracket thresholds annually — they adjust for inflation.)* ### Bracket Strategies - **Identify current bracket**: Based on estimated taxable income (AGI − deductions) - **Optimize around thresholds**: "You're $X away from the next bracket — a Traditional IRA contribution / additional 401k / business expense would keep you in the lower bracket" - **Roth conversion planning**: Fill up the current bracket with Roth conversions (convert just enough to stay in current bracket, pay tax at known rate, grow tax-free) - **Capital gains brackets**: Long-term capital gains taxed at 0% (up to ~$48k single), 15% (up to ~$533k), 20% above that. Plan sales around these thresholds. - **Income smoothing**: If income varies year-to-year, accelerate deductions in high-income years, defer to low-income years --- ## Estimated Tax Calculator ### When Estimated Payments Are Required - Expect to owe $1,000+ in tax after withholding and credits - Self-employment income, investment income, rental income, etc. - Penalty-free if you meet safe harbor rules ### Safe Harbor Rules - **Pay 100% of prior year's tax liability** through withholding + estimated payments — no penalty regardless of current year income - **110% rule**: If AGI exceeds $150,000 ($75,000 MFS), must pay 110% of prior year's tax - **Alternative**: Pay 90% of current year's tax liability - Meet either threshold to avoid underpayment penalty (Form 2210) ### Calculation Method 1. Estimate current year total income (W-2 + 1099 + investments + other) 2. Subtract above-the-line deductions (401k, IRA, HSA, SE tax deduction, etc.) 3. Subtract standard deduction or estimated itemized deductions 4. Apply tax brackets to get estimated tax 5. Subtract W-2 withholding and credits 6. Divide remaining tax by 4 for quarterly payments 7. Compare against safe harbor amount — pay whichever strategy is preferred ### Track Estimated Payments Log in the expense file under `estimatedPayments` array: ```json { "quarter": "Q1", "dueDate": "YYYY-04-15", "amount": 2500, "paid": true, "datePaid": "YYYY-04-10", "confirmationNumber": "EFTPS-12345" } ``` --- ## Audit Risk Assessment ### Audit Red Flags 🚩 | Risk Factor | Audit Risk | Why | |------------|-----------|-----| | Schedule C deductions > 50% of gross income | **HIGH** | IRS computers flag disproportionate deductions | | Home office deduction | **MEDIUM** | Historically scrutinized; simplified method is safer | | Cash-heavy business income | **HIGH** | IRS suspects underreporting | | Large charitable deductions (>5% of income) | **MEDIUM** | Especially non-cash donations | | Hobby losses (losses year after year) | **HIGH** | Must show profit 3 of 5 years | | Round numbers on every line | **MEDIUM** | Suggests estimation, not actual records | | High meal/entertainment deductions | **MEDIUM** | Must document business purpose for each | | Vehicle 100% business use | **HIGH** | IRS skeptical anyone uses vehicle 100% for business | | Excessive business travel | **MEDIUM** | Must demonstrate business necessity | | Missing or zero income on Schedule C with large deductions | **HIGH** | Looks like a tax shelter | | Rental losses with high income (passive activity rules) | **MEDIUM** | $25k rental loss allowance phases out at $100–150k AGI | ### Documentation Levels **Low-Risk Deductions** (standard records): - W-2 withholding, standard deduction, basic retirement contributions - Keep: W-2s, 1099s, contribution statements - Standard recordkeeping is sufficient **Medium-Risk Deductions** (detailed records + contemporaneous notes): - Home office, vehicle expenses, business meals, charitable giving - Keep: Receipts, mileage log (daily), home office measurements/photos, meal logs with business purpose - Contemporaneous notes (recorded at or near the time of the expense) **High-Risk Deductions** (professional documentation, appraisals): - Large non-cash charitable donations (>$5,000 requires qualified appraisal) - Section 179 on vehicles, business use of personal assets, entity structure deductions - Keep: Professional appraisals, detailed business plans, formal agreements, photos/documentation of business use - Consider professional tax preparer review ### General Documentation Best Practices - **Receipt rule**: Keep receipts for everything >$75 (IRS requirement). Best practice: keep ALL business receipts. - **Contemporaneous logs**: Mileage, meals, and home office use should be logged when they happen, not reconstructed later - **Business purpose**: Always document WHY an expense is business-related - **Photographic evidence**: Home office setup, business equipment, vehicle condition - **Separate accounts**: Use a dedicated business bank account and credit card --- ## Life Event Tax Triggers When the user mentions a life event, proactively walk through tax implications: ### Marriage / Divorce - **Filing status change**: Married Filing Jointly (usually best), Married Filing Separately, or back to Single - **Name change**: Update SSA (Form SS-5) before filing - **Asset transfers**: Transfers between spouses during marriage are tax-free (IRC §1041) - **Divorce**: Property division is generally tax-free; alimony rules depend on divorce date (pre-2019: deductible by payer/income to recipient; post-2018: no tax effect) - **Review withholding**: Immediately update W-4 after status change ### New Baby / Dependent - **Child Tax Credit**: Up to $2,000 per qualifying child (check phase-out at $200k single / $400k married) - **Dependent Care FSA**: Up to $5,000/year pre-tax for childcare - **529 Plan**: State tax deduction for contributions (varies by state) - **Head of Household**: If unmarried with qualifying dependent — lower tax rates than Single - **EITC**: If income qualifies, Earned Income Tax Credit is significant ### Home Purchase / Sale - **Purchase**: Mortgage interest deduction (up to $750k loan), property tax deduction (SALT cap $10k), points paid at closing may be deductible - **Sale**: Capital gains exclusion — $250k single / $500k married (must live in home 2 of last 5 years) - **Home office**: If you have a home office, portion of home sale may not qualify for exclusion (depreciation recapture) ### Job Change - **401(k) rollover**: Roll old employer 401k into new employer plan or IRA. Do NOT cash out (10% penalty + income tax). - **Moving expenses**: Not deductible for most taxpayers (TCJA suspended; only active military) - **Review withholding**: Immediately update W-4 at new employer - **Negotiate**: Sign-on bonus, relocation reimbursement, equity vesting schedule — all have tax implications - **Gap in employment**: If between jobs, may have lower income year — opportunity for Roth conversion ### Retirement - **RMDs (Required Minimum Distributions)**: Must begin at age 73 (SECURE 2.0 Act). Failure penalty: 25% of amount not withdrawn (reduced to 10% if corrected timely). - **Social Security taxation**: Up to 85% of benefits may be taxable depending on combined income - **Medicare IRMAA surcharges**: If income exceeds threshold (>$103k single, >$206k married), Medicare Part B and D premiums increase. Income is based on 2-year lookback. - **Roth conversions before RMDs**: Strategic opportunity to convert in lower-income years before RMDs begin ### Death of Spouse - **Surviving spouse filing status**: Can file jointly for year of death; qualifying surviving spouse status for 2 years after if you have a dependent child - **Stepped-up basis**: Inherited assets get cost basis stepped up to FMV at date of death (huge tax benefit) - **Estate tax**: Federal exemption ~$13.6 million (2025). Most estates not affected. Check state estate/inheritance tax. - **Beneficiary designations**: Review all retirement accounts, life insurance, bank accounts ### Starting a Business - **Entity selection**: Sole prop (simplest), LLC (liability protection), S-Corp (tax optimization) — see Entity Structure section - **EIN**: Apply for free at irs.gov (instant online) - **Estimated payments**: Required from day one if you expect to owe $1,000+ - **Home office**: Immediately deductible if you have a dedicated space - **Startup costs**: First $5,000 deductible immediately; excess amortized over 15 years - **Business bank account**: Open immediately to separate personal and business finances ### Moving to a New State - **Residency rules**: Most states define resident as living there 183+ days. Some use domicile (intent to remain). - **Multi-state filing**: May need to file part-year returns in both old and new state - **Income allocation**: W-2 income typically taxed by state where work is performed; business income may be apportioned - **Moving date matters**: Moving mid-year means filing in both states - **No income tax states**: Moving to TX, FL, NV, WA, WY, SD, AK eliminates state income tax --- ## Multi-State Filing Awareness ### When Multi-State Filing Is Required - Lived in more than one state during the year - Earned income in a state other than your resident state - Work remotely for employer in a different state (some states claim taxing authority) - Own rental property or business income in another state ### Key Concepts - **Domicile**: Your permanent home — where you intend to return. Only one domicile at a time. - **Residency**: Where you physically live. Can be "resident" of one state and "statutory resident" of another (usually 183+ days). - **Source income**: Income earned within a state's borders (work performed there, property located there, business operated there) - **Credits**: Most states give credit for taxes paid to other states on the same income (avoid true double taxation) ### States with No Income Tax Alaska, Florida, Nevada, New Hampshire (interest/dividends only), South Dakota, Tennessee, Texas, Washington, Wyoming ### Reciprocity Agreements Some neighboring states have agreements where you only pay tax to your home state (e.g., VA/DC/MD, IL/IN/IA/KY/MI/WI). Check if your states have reciprocity. ### Allocation and Apportionment - **W-2 income**: Usually apportioned by days worked in each state - **Business income**: May use sales factor, payroll factor, or property factor depending on state - **Investment income**: Generally taxed only by resident state ### Full-Time RVer Considerations - Must establish domicile in one state (driver's license, voter registration, vehicle registration, mail forwarding address) - That state is your resident state for tax purposes - If you work while traveling through other states, technically may owe tax to those states (enforcement varies) - Popular domicile states for RVers: South Dakota, Texas, Florida (no income tax + easy residency) --- ## RV-as-Home Tax Rules An RV qualifies as a "home" for federal tax purposes if it has **sleeping, cooking, and toilet facilities**. This opens several deductions: ### Mortgage Interest Deduction - If the RV is financed, loan interest may be deductible as **home mortgage interest** - RV can be your primary residence or second home - Subject to the $750,000 mortgage limit (combined across all qualified homes) - Report on Schedule A (itemized deductions) ### Home Office in RV - Same rules as traditional home office: **regular and exclusive use** as your principal place of business - Simplified method: $5/sqft, max 300sqft = $1,500 - Actual method: percentage of RV costs (loan interest, insurance, park fees, utilities, maintenance, depreciation) - **Only available for self-employed / 1099 income** — not W-2 employees ### Property Tax on RV - May be deductible as **personal property tax** (not real property tax) - Varies by state and county — some jurisdictions assess personal property tax on RVs, some don't - Vehicle license tax (ad valorem portion) may qualify as deductible personal property tax - Subject to SALT cap ($10,000 combined state/local/property) ### Full-Time RVer Special Considerations - **Domicile state**: Must establish legal domicile (driver's license, voter registration, mail forwarding) - **Mail forwarding services**: Available in SD, TX, FL — these states also have no income tax - **Voter registration**: Register in domicile state - **Insurance**: Must match domicile state - **Health insurance**: ACA marketplace based on domicile ZIP code - **Business address**: Use domicile address or registered agent for business filings --- ## Document Retention Guide ### How Long to Keep Tax Records | Document Type | Retention Period | Notes | |--------------|-----------------|-------| | **Tax returns** | **Forever** (or minimum 7 years) | You may need them for mortgage applications, government audits, estate planning | | **W-2s, 1099s, K-1s** | 3 years minimum | 6 years if underreporting suspected; 7 if loss deduction claimed | | **Receipts & expense records** | 3 years minimum | Keep 6–7 years for safety | | **Property records** (home, vehicle) | Until 3 years after you dispose of the property | Need cost basis for gain/loss calculation | | **Investment records** (purchase/sale) | Until 3 years after you sell | Broker statements, trade confirmations, cost basis | | **Business records** | 7 years | Even after closing the business | | **Employment tax records** | 4 years after tax is due or paid (whichever is later) | If you have employees | | **IRA contribution records** | Until all funds are withdrawn + 3 years | Need to track basis for non-deductible contributions | | **Home improvement records** | Until 3 years after home is sold | Add to cost basis, reduce taxable gain | ### Digital Record Keeping Tips - Scan all paper receipts and store digitally (paper fades) - Organize by year and category - Back up to cloud storage - Save bank/credit card statements (backup documentation) - Screenshot or save digital receipts (email confirmations, app purchases) --- ## Integration Hooks ### Mechanic Skill Integration When the mechanic skill (`skills/mechanic/SKILL.md`) logs a vehicle service: - If the vehicle has `business_use: true` or a `business_use_percent > 0` in `data/mechanic/state.json`, the maintenance expense is deductible - Deductible amount = cost × business_use_percent (if using actual expense method) - NOT separately deductible if using standard mileage rate (already included in rate) - The mechanic skill should suggest logging deductible portions to `data/tax-professional/YYYY-expenses.json` ### Card Optimizer Integration - Purchase categories from `skills/card-optimizer/SKILL.md` can help identify potentially deductible expenses - Business purchase categories: office supplies, software, travel, gas, internet - Cross-reference `data/card-optimizer/cards.json` for spending category analysis ### Data Paths - Tax profile: `data/tax-professional/tax-profile.md` (user's tax-relevant info: filing status, employment, deductions) - Tax expenses: `data/tax-professional/YYYY-expenses.json` - Tax return analyses: `data/tax-professional/YYYY-return-analysis.md` - Mechanic state: `data/mechanic/state.json` - Card data: `data/card-optimizer/cards.json` --- ## Staying Current ⚠️ **Tax law changes frequently.** Before applying any strategy: 1. Verify current-year rules at [irs.gov](https://www.irs.gov) 2. Check if TCJA provisions have been extended, modified, or expired 3.
