Future Developments

For the latest information about 

developments related to Form 6252 and 

its instructions, such as legislation 

enacted after they were published, go to 

www.irs.gov/Form6252.

What’s New

Special rules for capital gains invested 

in Qualified Opportunity Funds. In 

2018, if you have a capital gain you can 

invest that gain into a Qualified 

Opportunity Fund and elect to defer part 

or all of the gain that you would 

otherwise include in income until 

December 31, 2026. You also may be 

able to permanently exclude gain from 

the sale or exchange of an investment in 

a Qualified Opportunity Fund if the 

investment is held for at least 10 years. 

For information about how to elect to 

use these special rules, see the 

Instructions for Form 8949.

Purpose of Form

Use Form 6252 to report income from an 

installment sale on the installment 

method. Generally, an installment sale is 

a disposition of property where at least 

one payment is received after the end of 

the tax year in which the disposition 

occurs. Ordinarily, an installment sale 

doesn’t include a disposition of personal 

property by a person who regularly sells 

or otherwise disposes of personal 

property of the same type, or a 

disposition of real property which is held 

by the taxpayer for sale to customers in 

the ordinary course of the taxpayer’s 

trade or business. However, gain on 

some dispositions by dealers in real 

property or farmers who dispose of any 

property used or produced in the trade 

or business of farming may be reported 

on the installment method.

Don’t file Form 6252 for sales that 

don’t result in a gain, even if you will 

receive a payment in a tax year after the 

year of sale. Instead, report the entire 

sale on Form 4797, Sales of Business 

Property, Form 8949, Sales and Other 

Dispositions of Capital Assets, or the 

Schedule D for your tax return, 

whichever applies.

Don’t file Form 6252 to report sales 

during the tax year of stock or securities 

traded on an established securities 

market. Instead, treat all payments as 

received during the year of sale.

Don’t file Form 6252 if you elect not to 

report the sale on the installment 

method. To elect out, report the full

amount of the gain on a timely filed 

return (including extensions) on Form 

4797, Form 8949, or the Schedule D for 

your tax return, whichever applies. If you 

filed your original return on time without 

making the election, you can make the 

election on an amended return filed no 

later than 6 months after the due date of 

your tax return, excluding extensions. 

Write “Filed pursuant to section 

301.9100-2” at the top of the amended 

return.

Which Parts To Complete

Year of Sale

Complete lines 1 through 4, Part I, and 

Part II. If you sold property to a related 

party during the year, also complete 

Part III.

Later Years

Complete lines 1 through 4 and Part II 

for any year in which you receive a 

payment from an installment sale.

If you sold a marketable security to a 

related party after May 14, 1980, and 

before 1987, complete Form 6252 for 

each year of the installment agreement, 

even if you didn’t receive a payment. 

Complete lines 1 through 4. Complete 

Part II for any year in which you receive a 

payment from the sale. Complete Part III 

unless you received the final payment 

during the tax year.

After 1986, the installment method 

isn’t available for the sale of marketable 

securities.

If you sold property other than a 

marketable security to a related party 

after May 14, 1980, complete Form 6252 

for the year of sale and for 2 years after 

the year of sale, even if you didn’t 

receive a payment. Complete lines 1 

through 4. Complete Part II for any year 

during this 2-year period in which you 

receive a payment from the sale. 

Complete Part III for the 2 years after the 

year of sale unless you received the final 

payment during the tax year.

Special Rules

Interest

If any part of an installment payment you 

received is for interest or original issue 

discount, report that income on the 

appropriate form or schedule. Don’t 

report interest received, carrying charges 

received, or unstated interest on Form 

6252. See Pub. 537, Installment Sales, 

for details on unstated interest.

Installment Sales to Related Party

A special rule applies to a first 

disposition (sale or exchange) of 

property under the installment method to 

a related party who then makes a 

second disposition (sale, exchange, gift, 

or cancellation of installment note) 

before making all payments on the first 

disposition. For this purpose, a related

party includes your spouse, child, 

grandchild, parent, brother, sister, or a 

related corporation, S corporation, 

partnership, estate, or trust. See section 

453(f)(1) for more details.

Under this rule, treat part or all of the 

amount the related party realized (or the 

fair market value (FMV) if the disposed 

property isn’t sold or exchanged) from 

the second disposition as if you received 

it from the first disposition at the time of 

the second disposition. Figure the gain, 

if any, on lines 30 through 37. This rule 

doesn’t apply if any of the conditions 

listed on line 29 are met.

Sale of Depreciable Property to 

Related Person

Generally, if you sell depreciable property 

to a related person (as defined in section 

453(g)(3)), you can’t report the sale using 

the installment method. For this purpose, 

depreciable property is any property that 

(in the hands of the person or entity to 

whom you transfer it) is subject to the 

allowance for depreciation. However, you 

can use the installment method if you can 

show to the satisfaction of the IRS that 

avoidance of federal income taxes wasn’t 

one of the principal purposes of the sale 

(for example, no significant tax deferral 

benefits will result from the sale). If the 

installment method doesn’t apply, report 

the sale on Form 4797, Form 8949, or 

Schedule D, whichever applies. Treat all 

payments you will receive as if they were 

received in the year of sale. Use FMV for 

any payment that is contingent as to 

amount. If the FMV can’t be readily 

determined, basis is recovered ratably.

Pledge Rule

For certain dispositions under the 

installment method, if an installment 

obligation is pledged as security on a 

debt, the net proceeds of the secured 

debt are treated as payment on the 

installment obligation. However, the 

amount treated as payment can’t be 

more than the excess of the total 

installment contract price over any 

payments received under the contract 

before the secured debt was obtained.

An installment obligation is pledged as 

security on a debt to the extent that 

payment of principal and interest on the 

debt is directly secured by an interest in 

the installment obligation. For sales after 

December 16, 1999, payment on a debt 

is treated as directly secured by an 

interest in an installment obligation to the 

extent an arrangement allows you to 

satisfy all or part of the debt with the 

installment obligation.

The pledge rule applies to any 

installment sale after 1988 with a sales 

price of over $150,000 except:

• Personal use property disposed of by 

an individual,

• Farm property, and

• Timeshares and residential lots.
Form 6252 (2018) Page 3 

However, the pledge rule doesn’t apply 

to pledges made after December 17, 

1987, if the debt is incurred to refinance 

the principal amount of a debt that was 

outstanding on December 17, 1987, and 

was secured by nondealer installment 

obligations on that date and at all times 

after that date until the refinancing. This 

exception doesn’t apply to the extent 

that the principal amount of the debt 

resulting from the refinancing exceeds 

the principal amount of the refinanced 

debt immediately before the refinancing. 

Also, the pledge rule doesn’t affect 

refinancing due to the calling of a debt by 

the creditor if the debt is then refinanced 

by a person other than this creditor or 

someone related to the creditor.

Interest on Deferred Tax

Generally, you must pay interest on the 

deferred tax related to any obligation 

that arises during a tax year from the 

disposition of property under the 

installment method if:

• The property had a sales price over 

$150,000; and

• The aggregate balance of all nondealer 

installment obligations arising during, 

and outstanding at the close of, the tax 

year is more than $5 million.

You must pay interest in subsequent 

years if installment obligations that 

originally required interest to be paid are 

still outstanding at the close of a tax year.

The interest rules don’t apply to 

dispositions of:

• Farm property,

• Personal use property by an individual,

• Real property before 1988, or

• Personal property before 1989.

See section 453(l) for more information 

on the sale of timeshares and residential 

lots under the installment method.

How to report the interest. The interest 

isn’t figured on Form 6252. See Pub. 537 

for details on how to report the interest.

Additional Information

See Pub. 537 for additional information, 

including details about reductions in 

selling price, the single sale of several 

assets, like-kind exchanges, dispositions 

of installment obligations, and 

repossessions.

Line 21

Enter all money and the FMV of any 

property or services you received in 

2018. Include as payments any amount 

withheld to pay off a mortgage or other 

debt or to pay broker and legal fees. 

Generally, don’t include as a payment 

the buyer’s note, a mortgage, or other 

debt assumed by the buyer. However, a 

note or other debt that is payable on 

demand or readily tradable in an 

established securities market is 

considered a payment. For sales 

occurring before October 22, 2004, a 

note or other debt is considered a 

payment only if it was issued by a 

corporation or governmental entity. If 

you didn’t receive any payments in 2018, 

enter zero. If in prior years an amount 

was entered on the equivalent of line 34 

of the 2018 form, don’t include it on this 

line. Instead, enter it on line 23. See

Pledge Rule, earlier, for details about 

proceeds of debt secured by installment 

obligations that must be treated as 

payments on installment obligations.

Line 23

Enter all money and the FMV of property 

or services you received before 2018 

from the sale. Include allocable 

installment income and any other 

deemed payments from prior years.

Line 25

Enter here and on Form 4797, line 15, 

any ordinary income recapture on 

section 1252, 1254, or 1255 property for 

the year of sale or all remaining 

recapture from a prior year sale. Don’t 

enter ordinary income from a section 179 

expense deduction. If this is the year of 

sale, complete Form 4797, Part III. The 

amount from line 27c, 28b, or 29b of 

Form 4797 is the ordinary income 

recapture. Don’t enter any gain for this 

property on line 31 or 32 of Form 4797. If 

you used Form 4797 only to figure the 

recapture on line 25 or 36 of Form 6252, 

enter “N/A” on lines 31 and 32 of Form 

4797.

Also report on this line any ordinary 

income recapture remaining from prior 

years on section 1245 or 1250 property 

sold before June 7, 1984.

Don’t enter on line 25 more than the 

amount shown on line 24. Any excess 

must be reported in future years on Form 

6252 up to the taxable part of the 

installment sale until all of the recapture 

has been reported.

Line 26

For trade or business property held more 

than 1 year, enter this amount on Form 

4797, line 4. If the property was held 1 

year or less or you have an ordinary gain 

from the sale of a noncapital asset (even 

if the holding period is more than 1 year), 

enter this amount on Form 4797, line 10, 

and write “From Form 6252.” If the 

property was section 1250 property 

(generally, real property that you 

depreciated) held more than 1 year, 

figure the total amount of unrecaptured 

section 1250 gain included on line 26 

using the Unrecaptured Section 1250 

Gain Worksheet in the Instructions for 

Schedule D (Form 1040).

For capital assets, enter this amount 

on Schedule D as a short- or long-term 

gain on the lines identified as from Form 

6252.

Part III—Related Party 

Installment Sale Income

Line 29

If one of the conditions is met, check the 

appropriate box and skip lines 30 

through 37. If you checked box 29e, 

attach an explanation. Generally, the 

nontax avoidance exception will apply to 

the second disposition if:

• The disposition was involuntary (for 

example, a creditor of the related party 

foreclosed on the property or the related 

party declared bankruptcy); or

• The disposition was an installment sale 

under which the terms of payment were 

substantially equal to or longer than 

those for the first sale. However, the 

resale terms must not permit significant 

deferral of recognition of gain from the 

first sale (for example, amounts from the 

resale are being collected sooner).

Line 30

If the related party sold all or part of the 

property from the original sale in 2018, 

enter the amount realized from the part 

resold. If part was sold in an earlier year 

and part was sold this year, enter the 

cumulative amount realized from the 

resale.

Amount realized. The amount realized

from a sale or exchange is the total of all

money received plus the FMV of all

property or services received. The

amount realized also includes any

liabilities that were assumed by the 

buyer and any liabilities to which the 

property transferred is subject, such as 

real estate taxes or a mortgage. For 

details, see Pub. 544, Sales and Other 

Dispositions of Assets.

Line 33

If you completed Part II, enter the sum of 

lines 22 and 23. Otherwise, enter all 

money and the FMV of property you 

received before 2018 from the sale. 

Include allocable installment income and 

any other deemed payments from prior 

years. Don’t include interest, whether 

stated or unstated.

Line 36

See the instructions for line 25. Don’t 

enter on line 36 more than the amount 

shown on line 35. Any excess must be 

reported in future years on Form 6252 up 

to the taxable part of the installment sale 

until all of the recapture has been 

reported.

Line 37

See the instructions for line 26.
