An S-Corporation can have a profitable year on paper and still leave its owner with a tax problem. A Schedule K-1 that shows a loss does not mean the owner can deduct it, and a distribution that feels like your own money is not always tax free. Both outcomes depend on one number most owners never see until filing season: shareholder basis.
Basis is the running total of what you have invested in the company, plus income it has passed through to you, minus losses and distributions. It resets every year, and it is measured on the last day of the corporation’s tax year. For a calendar year S-Corporation, that means December 31. [irs]
Once that date passes, the basis for 2026 is fixed. The fix has to happen before the year closes, not when the return is prepared.
Tax problems are easier to manage before the IRS process controls the timeline. If you want a practical review of your basis position before December 31, speak with Steve Perry, EA. Call 678-717-9818, email steve@bookstaxesatl.com, or connect on LinkedIn at www.linkedin.com/in/steveperrybtm.
The Order That Catches Owners Off Guard
The IRS applies basis adjustments in a set order. Income increases basis first. Distributions reduce it next. Losses and deductions come last. [irs]
That order matters. Because distributions are subtracted before losses, cash taken out during the year can use up the basis a loss would have needed. When distributions exceed stock basis, the excess is taxed as a capital gain. When losses exceed stock and debt basis combined, the excess is suspended and carried forward until basis is restored.
Think of basis like a bank balance that is reconciled once a year. The withdrawals are posted before the year end charges, and anything that does not fit is either taxed now or pushed to next year.
A Worked Example With an Equipment Purchase
Consider an owner of a single shareholder S-Corporation with stock basis of $80,000 at the start of 2026. The company expected a $150,000 profit, so the owner took $100,000 in distributions over the year.
In November, the company buys $200,000 of equipment. With the full first year deduction, the expected $150,000 profit turns into a $50,000 loss. [irs]
Here is how the year closes if nothing else happens:
- There is no income to add, so basis starts at $80,000
- The $100,000 of distributions reduces basis to zero, and the $20,000 excess is taxable capital gain
- The $50,000 loss has no basis left to absorb it, so the full amount is suspended
The owner expected a deduction and instead receives a taxable gain. The equipment purchase was a sound business decision. The timing of the cash and the basis calculation were never reviewed together.
Now consider what can be done before December 31:
- A $20,000 capital contribution restores enough stock basis to cover the distributions, eliminating the capital gain
- A direct, documented $50,000 loan from the owner to the company creates debt basis to absorb the loss
- A single $70,000 contribution can accomplish both
- The company may choose to claim less first year depreciation, if it makes more sense to spread the deduction over future years
There may be other options depending on the facts and circumstances. Each one depends on the owner’s cash position, the company’s needs, and records that show the money moved before year end.

Why Loans and Contributions Are Not Interchangeable
The two fixes work differently. Only stock basis protects distributions. Debt basis does not count when deciding whether a distribution is taxable, so a loan helps the loss but not the gain. [irs]
Debt basis also has strict limits. It comes only from money you personally lend to the corporation. Guaranteeing a bank loan for the company does not create debt basis. And once losses reduce the basis of a shareholder loan, a later repayment of that loan can be partly taxable.
A loan should look like a loan. A signed note, a stated interest rate, a repayment schedule, and a bank record of the transfer are what separate debt basis from a disputed claim.
How the IRS Reviews Basis
Beginning with 2021 returns, shareholders who claim a loss, receive a distribution, dispose of stock, or receive a loan repayment generally must file Form 7203 with their return. The IRS also states that shareholders are responsible for keeping the information needed to figure their basis. [irs]
The form exists for a reason. The IRS ran a compliance campaign focused on S-Corporation losses claimed in excess of basis, including distributions in excess of basis that were never reported as taxable. [irs]
Examiners are trained to look at the same pressure points: losses claimed beyond basis, company payments of personal expenses, and repayments of reduced basis loans. [irs]
When basis has never been tracked, it has to be rebuilt from the year the stock was acquired. Every missing return, K-1, or bank record makes that harder. A shareholder who cannot prove basis may lose a deduction that was otherwise valid.
If IRS notices, missing basis records, unexplained distributions, or planning gaps are starting to create concern, speak with Steve Perry, EA before the problem becomes harder to control. Call 678-717-9818, email steve@bookstaxesatl.com, or connect on LinkedIn at www.linkedin.com/in/steveperrybtm.
Basis Is a Year-Round Measurement
Basis changes with every distribution, every loss, and every contribution. Many S-Corporation issues do not begin with a filing mistake. They begin when distributions are taken without a basis check, when a large purchase changes the year’s results and no one runs the numbers, or when a K-1 arrives and the basis records do not exist.
Good tax outcomes come from managing the year before the IRS forces the issue.

Frequently Asked Questions
Can I fix a basis shortfall after December 31?
Generally no. Basis is measured at the end of the corporation’s tax year, so contributions and loans made in January count toward the next year.
Are suspended losses lost forever?
No. They carry forward indefinitely and can be used when basis is restored. They are lost if you dispose of all your stock before using them.
Does guaranteeing a company loan give me basis?
No. Debt basis comes only from money you personally lend to the corporation.
Why was my distribution taxed when the company had cash to pay it?
Distributions reduce basis before losses do, and cash in the bank is not the same as basis. If distributions exceed stock basis, the excess is taxable.
Do I need Form 7203 every year?
It is required in years you claim a loss, receive a distribution, sell stock, or receive a loan repayment. Completing it every year keeps basis records continuous.
