How to Convert a Shareholder Loan to Paid-In Capital

To convert a shareholder loan to paid-in capital, you cancel the loan on the corporation’s books and replace it with equity: draft a debt conversion agreement, get board approval, either issue new shares to the shareholder or accept the loan as a capital contribution, and record a journal entry that debits the loan payable and credits common stock and additional paid-in capital. The path you pick between those two structures determines whether the corporation recognizes cancellation of debt income, so decide the tax treatment before you draft the paperwork.

Pick the Structure Before You Draft Anything

There are two ways to do this transaction, and federal tax law treats them differently.

In the first, the shareholder contributes the loan to the corporation’s capital without receiving new shares. Section 108(e)(6) then treats the corporation as having satisfied the debt with an amount equal to the shareholder’s adjusted basis in the loan.¹ A shareholder who lent cash usually has a basis equal to the outstanding principal, so a $100,000 loan contributed to capital is treated as a $100,000 payment against $100,000 of debt, and no cancellation of debt (COD) income arises. The shareholder’s existing stock becomes more valuable, but no new certificates are issued.

In the second, the corporation issues new shares in exchange for the loan. Section 108(e)(8) then treats the corporation as having satisfied the debt with money equal to the fair market value of the stock issued.¹ If the stock is worth less than the debt, the difference is COD income to the corporation. A $100,000 loan swapped for stock worth $80,000 produces $20,000 of taxable income.² Match the valuation to the debt and the tax disappears; miss on valuation and you create a bill.

For a closely held company where the shareholder already owns most or all of the stock, the contribution path (108(e)(6)) is often the cleaner route because it sidesteps the valuation risk entirely. Issue new shares only if the transaction needs to change ownership percentages or bring in a new class of stock.

Verify the Loan and Get a Valuation

Pull the original promissory note and confirm the exact outstanding principal, the interest rate, and any accrued but unpaid interest. That total is the dollar figure that drives the journal entry, the share count if you’re issuing stock, and the tax analysis. If the loan is informal or missing documentation, fix that before doing anything else, because a “loan” the IRS can recharacterize as equity puts every past interest deduction at risk (see the Section 385 discussion below).

If you’re taking the stock-issuance path, you need a defensible fair market value for the shares. For a private company, that usually means a third-party appraisal. Small business valuations typically run from $2,000 to $30,000 depending on complexity. That expense is cheap insurance against an IRS challenge years later.

Confirm Authorized Shares

Check the Articles of Incorporation for the number of authorized shares and how many are already outstanding. If there aren’t enough unissued shares available to complete the exchange, you’ll need to amend the Articles by filing with the Secretary of State, which usually requires a shareholder vote and a modest filing fee (typically $35 to $60). Build that time into your timeline.

Draft the Debt Conversion Agreement

The central document is a signed Debt Conversion Agreement between the corporation and the shareholder. It should state the total debt being canceled (principal plus any accrued interest), the number and class of shares being issued (if any), the price per share, and the effective date. Include representations that the shareholder understands they are receiving restricted securities and accepts the investment risk. Signing this before recording any entries gives auditors and the IRS a clear paper trail.

Get Board Approval

The board approves the conversion by resolution. The resolution authorizes cancellation of the specified debt, approves any share issuance at the stated price, and directs an officer to sign the agreement. Because this is an insider transaction, treat it with extra care. Courts in many states apply an “entire fairness” standard to controlling-shareholder deals rather than the more forgiving business judgment rule. Have independent directors lead the review where possible, and let the minutes reflect that the board considered the valuation and concluded the terms were fair.

Preemptive Rights and Shareholder Consent

If there are other shareholders, check the bylaws and Articles for preemptive rights, which entitle existing holders to buy a proportional share of any new issuance to avoid dilution. Most states no longer grant them automatically, but many corporate charters still include them.³ Where they apply, offer the other holders participation or get written waivers before closing. Under the Model Business Corporation Act, increasing authorized shares or creating a new class of stock requires approval by a majority of the votes entitled to be cast; a single-shareholder consent is easy but still needs to be documented.

Execute and Update the Ledger

An authorized officer signs for the corporation and the shareholder signs as the converting party. The signing date is the effective date for accounting and tax reporting. Update the stock ledger with the new share count and the shareholder’s revised ownership percentage, and either issue a certificate or record the uncertificated shares in the registry.

Record the Journal Entry

The entry moves the loan balance from a liability to equity, dollar for dollar. Debit Shareholder Loan Payable for the full principal being converted. Credit Common Stock for the par value of the newly issued shares, and credit Additional Paid-In Capital (APIC) for the remainder.

Say you’re converting a $100,000 loan into 10,000 shares with a $1.00 par value:

Debit Shareholder Loan Payable: $100,000
Credit Common Stock (10,000 × $1.00): $10,000
Credit APIC: $90,000

Under GAAP, when convertible debt is converted in accordance with its terms, the carrying amount of the debt is recognized in the capital accounts and no gain or loss is recorded.⁴ Total assets don’t change; the debt-to-equity ratio drops, which is usually the whole reason for doing this.

Accrued Interest

If unpaid interest is part of the conversion, first record it as an expense: debit Interest Expense, credit Interest Payable. Then include Interest Payable in the conversion entry alongside Shareholder Loan Payable, with the combined total credited to Common Stock and APIC. On the $100,000 example, adding $5,000 of accrued interest means converting $105,000: $10,000 to Common Stock, $95,000 to APIC.

Tax Consequences for the Corporation

The Contribution Path

Under Section 108(e)(6), the debt is treated as satisfied for an amount equal to the shareholder’s adjusted basis in it.¹ If the shareholder’s basis equals the principal (the ordinary case for a cash loan), no COD income results. This is why the contribution path is usually the tax-efficient choice for closely held companies.

The Stock-Issuance Path

Under Section 108(e)(8), the corporation is treated as satisfying the debt for the fair market value of the stock issued.¹ Any shortfall between that value and the debt is COD income. Match the values and there’s no income; miss and the corporation has taxable income to report.

Insolvency and Bankruptcy

If the corporation is insolvent (liabilities exceed the fair market value of assets), Section 108(a) excludes COD income to the extent of the insolvency. In a bankruptcy proceeding, the exclusion applies to the full amount.¹ The tradeoff is attribute reduction: net operating losses and certain other tax attributes must be reduced by the amount of excluded income.

Accrued Interest Watch-Out

If the corporation uses the accrual method and previously deducted interest that was never paid in cash, converting that accrued interest into equity can trigger income under the tax benefit rule. Cash-method corporations, which haven’t deducted unpaid interest, generally avoid this issue.

Tax Consequences for the Shareholder

If the shareholder transfers property to a corporation solely for stock and controls at least 80% of the corporation immediately after, Section 351 lets the transfer occur without recognizing gain or loss, and the shareholder takes a basis in the new stock equal to the basis in the property exchanged.⁵⁶

Here’s the catch. Section 351(d)(2) says stock issued for corporate indebtedness “which is not evidenced by a security” isn’t treated as issued for property.⁵ “Security” in tax law generally means a longer-term debt instrument. Short-term notes and demand loans often don’t qualify, so many routine shareholder loan conversions fall outside Section 351’s protection.

When Section 351 doesn’t apply, the exchange is taxable. The shareholder’s amount realized is the fair market value of the stock received; gain or loss is that value minus the basis in the debt (usually the outstanding principal). The new stock takes a basis equal to its fair market value at conversion, and the holding period starts on the conversion date. If the shareholder later sells the stock, any difference from that basis is capital gain or loss.

Don’t Let the Original Loan Get Reclassified

None of this works if the IRS decides the “loan” was really equity from the start. Section 385 authorizes the IRS to treat an instrument that looks like debt as stock for federal tax purposes.⁷ Reclassification disallows every interest deduction the corporation took and brings back taxes and penalties.

The statute lists factors the IRS weighs: whether there’s a written unconditional promise to pay a fixed sum on a specific date, whether the debt is subordinated to other obligations, the company’s debt-to-equity ratio, whether the instrument is convertible to stock, and whether the debt holdings mirror stock holdings.⁷ Treasury issued formal documentation regulations in 2016, but those specific documentation regulations were withdrawn in 2019; the statute and case-law factors still apply.⁸

Before initiating any conversion, confirm the original loan has a written promissory note, a stated principal, a reasonable interest rate, specific repayment dates, and a payment history consistent with the terms. A loan that looked like equity going in doesn’t become legitimate debt just because you’re converting it now.

Special Rules for S Corporations

If the corporation is an S corp, two additional issues apply. First, an S corp can have only one class of stock, though differences in voting rights alone don’t create a separate class.⁹ If the conversion issues shares with different distribution or liquidation rights than the existing stock, the S election terminates retroactive to the disqualifying event, and the company becomes a C corp for tax purposes.

Second, the original loan itself could already be a second class of stock unless it fits the “straight debt” safe harbor. Straight debt is a written unconditional promise to pay a fixed sum, with interest not tied to profits or management discretion, no convertibility into stock, and held by an eligible holder such as an individual or a bank.⁹ Notice the no-convertibility requirement: if the original note included a conversion feature, it never qualified for the safe harbor. An S corp should have a tax advisor confirm the S election survived the loan before worrying about whether it survives the new share issuance.

Securities Law Compliance

Issuing stock, even to an existing shareholder in exchange for debt, is a securities transaction. Federal law requires registration unless an exemption applies. Private companies typically rely on Rule 506 of Regulation D, which allows issuance to accredited investors without a cap or SEC registration. If you rely on Regulation D, file Form D with the SEC within 15 days after the first sale.¹⁰ Many states also require a separate blue sky notice filing. The new shares are restricted securities, which means the shareholder can’t freely resell them; non-reporting companies must hold restricted shares at least one year before resale becomes possible under Rule 144.

For a single-shareholder company converting their own loan, the compliance is simpler but still applies. Skipping the Form D usually creates no immediate penalty but can complicate later financings and due diligence.

What This Costs

Budget for professional fees. A qualified business valuation runs from a few thousand dollars for a straightforward small business to $30,000 or more for a complex entity. Legal fees for the conversion agreement, board resolutions, and any securities filings can add several thousand dollars. An amendment to the Articles of Incorporation to increase authorized shares typically costs $35 to $60 in state filing fees. Form D has no SEC filing fee, but state blue sky notices may. A conversion that fails IRS or judicial scrutiny costs far more to fix than to do correctly, so spend the money on documentation and valuation up front.
