Capital Contributions vs. Shareholder Loans
What is the difference between capital contributions and shareholder loans in an S corporation?

What You Need to Know
If you own an S corporation, there are two common ways to put money into the business:
1. A capital contribution — you invest more money into the company as an owner.
2. A shareholder loan — you lend money to the company and expect repayment.
They may feel similar from a cash-flow perspective, but they are treated very differently for tax purposes.
The distinction matters because S corporation shareholders must track both stock basis and debt basis. These basis amounts affect whether losses are deductible, whether distributions are taxable, and whether loan repayments create unexpected income. The IRS emphasizes that a shareholder’s Schedule K-1 does not by itself determine whether a distribution is taxable; that depends on the shareholder’s basis. (IRS)
Quick Visual: Capital vs. Loan
Capital Contributions: aka investment
A capital contribution is money or property contributed to the corporation in your capacity as a shareholder. Think of it as adding more equity to the business.
What it affects: Capital contributions generally increase your stock basis. Stock basis is important because it helps determine:
Whether S corporation losses can be deducted
Whether distributions are taxable
Gain or loss if the stock is sold
The tax treatment of non-dividend distributions
The IRS explains that stock basis starts with the shareholder’s initial capital contribution or cost of stock and is adjusted annually for income, losses, deductions, and distributions. (IRS)
Shareholder Loans: aka company debt
A shareholder loan is different. It means the shareholder lends money to the S corporation, and the corporation is obligated to repay it. To be respected by the IRS, the loan should be documented with a written promissory note and bear interest at least equal to the Applicable Federal Rate.
What it affects
A valid shareholder loan may create debt basis. Debt basis can matter when the shareholder’s stock basis has already been reduced to zero, but additional S corporation losses are passing through.
The IRS states that losses and deductions exceeding stock basis may be deductible to the extent the shareholder has basis in loans personally made to the S corporation. (IRS)
Make a capital contribution when:
✅ You want to strengthen the company’s balance sheet
✅ You do not need a fixed repayment schedule
✅ You are funding the company as an owner
✅ You want the contribution reflected as equity
Make a loan:
✅ The company needs temporary financing
✅ You expect repayment
✅ The company can support repayment
✅ You document the loan clearly
✅ You charge appropriate interest and follow the terms
