Form 7203, S Corporation Shareholder Stock and Debt Basis Limitations, is the form S corporation owners file with their personal return to show they have enough basis to deduct losses or take tax-free distributions. As of October 2026, you must file it if you claim a share of an S corp loss, received a non-dividend distribution, disposed of S corp stock or were repaid a loan by the company.
It replaced the three-part basis worksheet that used to sit in the Schedule K-1 shareholder instructions. The IRS's own advice is worth taking: complete it and keep it even in years you don't have to file, so your basis is tracked consistently year after year.
Who must file Form 7203
- Shareholders claiming a deduction for their share of an aggregate S corp loss, including a loss disallowed last year because of basis.
- Shareholders who received a non-dividend distribution.
- Shareholders who disposed of S corp stock, whether or not there's a gain.
- Shareholders who received a loan repayment from the S corporation.
If you're married filing jointly and you each got a Schedule K-1, each spouse completes a separate Form 7203.
Why basis decides your deduction
Your deduction for your share of losses and deductions on the K-1 is generally limited to the basis of your stock plus loans you've made to the company. Anything blocked by the basis limit carries forward indefinitely and can be used in a later year when you have basis again. And basis is the first of four limits applied in order:
- Basis limitation (Form 7203).
- At-risk limitation (Form 6198).
- Passive activity loss limitation (Form 8582).
- Excess business loss limitation (Form 461).
The order of stock basis adjustments
Stock basis starts as what you paid, or carryover basis for property contributed, fair market value at death for inherited stock, the donor's basis for a gift, or fair market value when included in income for stock received as pay. Each year it's adjusted in this order:
| Step | Adjustment | Effect |
|---|---|---|
| 1 | All income on the K-1, including tax-exempt income | Increases basis |
| 2 | Distributions reported in box 16, code D | Decreases basis, not below zero |
| 3 | Nondeductible expenses and certain oil and gas depletion | Decreases basis, not below zero |
| 4 | Losses and deductions on the K-1 | Decreases basis, not below zero |
You can elect under Regulations section 1.1367-1(g) to take losses (step 4) before nondeductible expenses (step 3). Once made, the election applies to that year and every later year for that S corporation unless the IRS agrees to revoke it, and you tick Item E to show it's in effect.
When a distribution becomes a capital gain
If a distribution is bigger than your stock basis before distributions, the excess is reported as a capital gain on Form 8949 and Schedule D, and your basis doesn't go up for that gain. Distributions from earlier C corporation earnings that come to you on Form 1099-DIV don't belong on line 6 at all.

Debt basis: the rules to know
- Loan basis is generally the balance the company owes you, adjusted for reductions and restorations.
- Losses that exceed stock basis then reduce loan basis.
- Distributions never reduce loan basis.
- A bank loan you guarantee or co-sign doesn't give you basis. You only get basis as a guarantor to the extent you make a payment under the guarantee.
- Stock basis and debt basis are worked out separately, in Parts I and II, and debt basis never goes on line 1.
Share sales go on a separate form, explained in our guide to reporting investment sales.
How to complete Form 7203
- Enter your name exactly as it appears on your K-1, and tick Item D for how you got the stock (purchase, inheritance, gift, original shareholder or other).
- Part I line 1: stock basis at the start of the year, normally last year's ending figure.
- Line 2: new capital contributions or stock purchases, but not loans.
- Line 3: positive income items from the K-1 only. Negative items go in Part III.
- Lines 6 to 8: distributions, then nondeductible items.
- Part II: debt basis, if you've lent the company funds.
- Part III: the allowable loss and deduction items, and what carries forward.
Two less obvious rules. Basis isn't increased by the S corporation's discharge of indebtedness income that's excluded under sections 108(a) and 108(d)(7)(A), so a debt write-off at company level doesn't hand you extra basis. And if there's a partial stock sale or partial redemption during the year, you may file more than one Form 7203, describing the period each one covers.
If you hold blocks of stock with different bases, items are generally allocated pro rata across all shares. The company itself files Form 1120-S and issues the K-1s; Form 7203 is the shareholder's side.

The verdict
If you own an S corp and take distributions or run a loss, you need a running basis record, and Form 7203 is it. Start one in the first year and update it every year from your K-1, because rebuilding basis from scratch years later is slow and the IRS puts the record-keeping duty on you. And don't count a personally guaranteed bank loan as basis: it isn't, until you pay it.

Frequently asked questions
Who has to file Form 7203?
S corporation shareholders who claim a loss deduction, receive a non-dividend distribution, dispose of stock or receive a loan repayment from the company.
Is Form 7203 needed in a year with no loss or distribution?
You may not have to file it, but the IRS says it may be beneficial to complete and keep it every year so your basis is consistently maintained.
Does a loan I guarantee count toward basis?
No. Loans a shareholder guarantees or co-signs aren't part of loan basis. You get basis only to the extent you make a payment under the guarantee.
What happens to losses I can't deduct because of basis?
They carry forward indefinitely and can be deducted in a later year, subject to the basis limit for that year.
Does Form 7203 replace the basis worksheet?
Yes. Form 7203 and its instructions replace the 3-part worksheet for figuring a shareholder's stock and debt basis that used to be in the Shareholder's Instructions for Schedule K-1 (Form 1120-S).
What if my distribution is more than my basis?
The excess is reported as a capital gain on Form 8949 and Schedule D, and you don't increase your stock basis for that gain.
