When an S corporation shareholder has taken pass-through losses that reduced the basis of a loan they made to the company, debt basis restoration for an S corp is the automatic rebuilding of that loan basis out of later years’ income. Under IRC Section 1367(b)(2)(B) and Treasury Regulation 1.1367-2(c), any “net increase” in a subsequent tax year has to restore the prior reduction in your debt basis before a single dollar can lift your stock basis.1Office of the Law Revision Counsel. 26 USC 1367 Adjustments to Basis of Stock of Shareholders The rule is mandatory, non-elective, and capped at the original face value of the loan.
How Losses Reduced Your Debt Basis
Every shareholder carries two separate pools of tax basis in an S corporation: stock basis and debt basis. Debt basis exists only where you personally lent money to the corporation through a direct economic outlay.2Internal Revenue Service. S Corporation Stock and Debt Basis
Under IRC Section 1366(d)(1), pass-through losses and deductions for any tax year cannot exceed the combined total of your stock basis and your debt basis.3Office of the Law Revision Counsel. 26 USC 1366 Pass-Thru of Items to Shareholders Losses follow a strict ordering rule. They have to reduce stock basis to zero first. Only after stock basis is exhausted can remaining losses eat into debt basis. That ordering matters, because it determines what needs restoring when income returns.
After losses have chewed through your debt basis, the corporation still owes you the full face value of the loan. The economic reality has not changed. But your tax basis in that loan is now lower than the amount you’re owed, and closing that gap is exactly what the restoration rules do.
How the Restoration Mechanism Works
Restoration doesn’t run on gross income. It runs on the “net increase” for the tax year, defined by Treasury Regulation 1.1367-2(c) as the amount by which your pro rata share of income items under Section 1367(a)(1) exceeds your pro rata share of loss, deduction, and distribution items under Section 1367(a)(2).4eCFR. 26 CFR 1.1367-2 Adjustments to Basis of Indebtedness to Shareholder If the corporation earns $80,000 of income but also passes through $80,000 of deductions and distributions in the same year, the net increase is zero. No restoration.
Where there is a net increase, it goes to debt basis first. You cannot choose to skip debt restoration and pump up stock basis instead, even if a higher stock basis would let you take tax-free distributions. The IRS designed this sequence specifically to block that kind of cherry-picking. Once debt basis is fully rebuilt to the original loan amount, any remaining net increase for that year (and for future years) flows through to stock basis in the ordinary way.
The timing is also fixed. All adjustments happen at the close of the S corporation’s tax year, and income increases and debt restoration are applied before distributions reduce stock basis. A distribution taken in March is measured against year-end basis as adjusted, not the basis that existed in March.
A Three-Year Example
You lent your S corporation $50,000, producing $50,000 of debt basis. In 2024, with stock basis already at zero, the corporation passed through $50,000 of losses that took your debt basis to zero. The corporation still owes you $50,000. Your tax basis in that loan is zero.
In 2025 the corporation generates $30,000 of net income, with no offsetting losses or distributions. The entire $30,000 net increase restores debt basis, from zero to $30,000. None of it can touch stock basis.
In 2026 the corporation generates $60,000 of net income. The first $20,000 finishes restoring debt basis back to $50,000, the original face value. The remaining $40,000 lifts your stock basis. Restoration is complete, and the system resets to normal operations.
The Face-Value Ceiling
Restoration is capped at the adjusted basis of the debt under Section 1016(a), determined as of the beginning of the tax year and excluding prior Section 1367 adjustments.4eCFR. 26 CFR 1.1367-2 Adjustments to Basis of Indebtedness to Shareholder In plain terms, you cannot restore debt basis above the loan’s original face value. The mechanism reverses prior reductions; it does not create new basis.
If You Hold More Than One Loan
Where a shareholder holds multiple loans to the corporation, any net increase is first applied to restore basis in any debt that was repaid (fully or partially) during the year, to the extent needed to prevent gain on the repayment. Whatever is left is then allocated proportionally among the other outstanding debts based on how much each one’s basis has been reduced.4eCFR. 26 CFR 1.1367-2 Adjustments to Basis of Indebtedness to Shareholder
Restoration also applies only to indebtedness held at the beginning of the tax year in which the net increase arises. Making a new loan to the corporation mid-year won’t let that new loan benefit from the current year’s restoration. It has to wait until the following year.
The Trap: Loan Repayment Before Restoration Is Complete
This is where most shareholders get tripped up. If the corporation repays part or all of the loan while your debt basis is still reduced, the repayment triggers taxable gain. The gain equals the difference between the amount repaid and your current basis in the loan, calculated proportionally for partial repayments.
For a partial repayment, use a pro rata formula: take the difference between the face amount and the reduced basis, divide by the face amount, and multiply by the repayment. Hold a $60,000 loan with a reduced basis of $45,000 and receive a $45,000 partial repayment, and the taxable gain is ($60,000 − $45,000) ÷ $60,000 × $45,000, or $11,250.
If the corporation pays the loan off in full before restoration is complete, the chance to restore basis on that instrument is lost. Restoration under Treasury Regulation 1.1367-2(c) applies only to indebtedness held at the beginning of the tax year in which the net increase arises.4eCFR. 26 CFR 1.1367-2 Adjustments to Basis of Indebtedness to Shareholder Once the loan no longer exists, there is nothing left to restore.
Written Note vs. Open Account
The character of the gain on a reduced-basis repayment depends on the paperwork. If the loan is evidenced by a written promissory note, the repayment is treated as a sale or exchange of the debt instrument under IRC Section 1271(a)(1), producing capital gain.5Office of the Law Revision Counsel. 26 USC 1271 Treatment of Amounts Received on Retirement or Sale or Exchange of Debt Instruments Hold the note more than 12 months and the gain qualifies as long-term capital gain, taxed at preferential rates.
If the loan is open account debt with no written instrument, the same gain is ordinary income. Open account debt covers informal shareholder advances where the aggregate outstanding principal stays at or below $25,000 at the close of the corporation’s tax year; go above that at year-end and the balance is permanently reclassified and treated like debt evidenced by a written instrument going forward.6GovInfo. 26 CFR 1.1367-2 Adjustments to Basis of Indebtedness to Shareholder The rate difference between long-term capital gain and ordinary income is substantial, which is why formal promissory notes are worth setting up before losses start reducing debt basis, not after.
What Restored Debt Basis Lets You Do
Once debt basis is back at face value and income starts flowing to stock basis, you return to normal S corporation treatment. Under IRC Section 1368, distributions from an S corporation without accumulated earnings and profits are tax-free to the extent they don’t exceed stock basis; amounts beyond stock basis are treated as gain from the sale of stock.7Office of the Law Revision Counsel. 26 USC 1368 Distributions
Restored debt basis also reloads your capacity to deduct future losses. If the company hits another rough stretch, that rebuilt debt basis is there once stock basis is exhausted again. Without restoration, those losses would sit suspended until you contributed more capital or made a new loan. Under IRC Section 1366(d)(2), disallowed losses carry forward indefinitely and are treated as if the corporation incurred them the following year.3Office of the Law Revision Counsel. 26 USC 1366 Pass-Thru of Items to Shareholders There is one critical exception. If the S election terminates, suspended losses can only be deducted during the post-termination transition period, and only against stock basis, not debt basis. Miss that window and the losses are permanently gone.
Tracking Restoration on Form 7203
Shareholders report basis calculations on IRS Form 7203, S Corporation Shareholder Stock and Debt Basis Limitations. The IRS recommends completing the form every year, even in years when filing it isn’t strictly required, to keep basis records continuous.8Internal Revenue Service. Instructions for Form 7203 S Corporation Shareholder Stock and Debt Basis Limitations
Part II handles debt basis. It asks for the beginning debt basis, any restoration from a net increase, reductions from current-year losses, the effect of any loan repayments, and the ending debt basis.9Internal Revenue Service. Form 7203 S Corporation Shareholder Stock and Debt Basis Limitations The income and loss figures come from the Schedule K-1 issued by the corporation.8Internal Revenue Service. Instructions for Form 7203 S Corporation Shareholder Stock and Debt Basis Limitations
The corporation does not track your individual basis. That falls on you. Keeping a continuous basis ledger separate from the corporation’s books is the only reliable way to support the tax treatment of distributions and loan repayments on audit. The IRS can disallow loss deductions or reclassify tax-free distributions as taxable income when a shareholder cannot produce basis documentation, and once debt basis has been reduced and partially restored across several years, reconstructing that history after the fact is difficult.
