How to Lend to Your Own Business

To lend money to your own business, put the transaction in writing as a promissory note, charge a reasonable market interest rate, deposit the funds into the business account (not commingled with operating cash), and record the debt on the books as a liability owed back to you — the shareholder or member. That paperwork is what turns a casual transfer into a real, defensible loan: it protects your ability to be repaid ahead of profit distributions, keeps the IRS from re-characterizing the money as a capital contribution or taxable income, and preserves the interest deduction for the business. The mechanics differ slightly by entity type (sole proprietor, LLC, S-corp, or C-corp), but the four pillars — a note, a rate, a clean deposit, and a ledger entry — hold in every case. This guide walks through each step, the tax treatment, a realistic example schedule, and the decision most owners actually face: whether to lend your own money at all, or to bring in outside business funding and keep your personal reserves intact.

The four things that make an owner loan real

A shareholder or member loan is only as strong as the trail behind it. If you ever face an audit, a partner dispute, or a bankruptcy, these four elements are what separate a loan from a gift or a disguised equity injection:

• A written promissory note. State the principal, the interest rate, the repayment schedule or maturity date, and what happens on default. Sign and date it. A note drafted after the money moved is far weaker than one signed the same day.
• A reasonable interest rate. The IRS publishes Applicable Federal Rates (AFRs) monthly — a floor for related-party loans. Charge at or above the AFR for your loan's term. Lending at zero interest can trigger imputed-interest rules, where the IRS treats you as if you earned interest anyway.
• A clean, traceable deposit. Move the funds by check or transfer directly into the business operating account. Do not pay vendors personally and call it a loan later; that muddies the record and invites re-characterization.
• A ledger entry. Book the money as a liability — "Loan from owner" or "Due to shareholder" — not as revenue and not as owner's equity. Every repayment should reduce that liability, with the interest portion recorded separately.

Skip any one of these and the transaction starts to look like something else. The most common failure is the handshake loan: cash moves, nothing is written, and two years later there is no way to prove it was ever meant to be repaid.

How the tax treatment works by entity type

The entity wrapper around your business changes how an owner loan is taxed on both sides — yours and the company's. The loan principal itself is never taxable income to the business (it is borrowed money), and repayment of principal is never deductible. Only the interest matters for taxes.

• Sole proprietor / single-member LLC (disregarded). You and the business are the same taxpayer for federal purposes, so a formal loan to yourself has limited tax effect — you cannot deduct interest paid to yourself. Documentation still matters for bookkeeping, liability protection, and future financing, but the tax mechanics are muted.
• Multi-member LLC / partnership. A loan from one member is real debt of the partnership. The partnership deducts the interest; the lending member reports that interest as income. Keep it separate from capital accounts.
• S-corporation. A shareholder loan increases your debt basis, which can let you deduct losses you otherwise could not. The company deducts interest; you report interest income. Be careful with repayments when basis has been reduced by losses — repaid principal can create gain.
• C-corporation. The cleanest interest story: the corporation deducts interest, and you report it as income. Because a C-corp is a separate taxpayer, the IRS scrutinizes whether "loans" are really disguised dividends — which is exactly why the note and market rate matter.

In every case, the interest the business pays you is ordinary income on your personal return. Talk to a CPA before you set the rate and structure, especially for S-corp basis planning.

Step-by-step: setting up the loan

1. Decide the amount and confirm you can spare it. Money you lend the business is money that is now illiquid and at risk. Only lend what you would not need back on short notice.
2. Pull the current AFR for the loan's term (short-, mid-, or long-term) and set your rate at or above it. Many owners charge a modest market rate rather than the bare minimum, which strengthens the "this is a real loan" position.
3. Draft the promissory note. Principal, rate, payment frequency, maturity, default terms, and whether it is secured or unsecured. Sign it.
4. Transfer the funds by traceable method into the business account on or before the note date.
5. Book it as a loan-from-owner liability in your accounting system.
6. Make the payments on schedule from the business account back to you, splitting each into principal and interest. Consistency here is the single best piece of evidence that the loan is genuine.
7. Issue year-end paperwork as your CPA advises, and report the interest you received.

The theme throughout: behave exactly as a bank would. A bank writes a note, charges interest, and expects scheduled payments. Mirror that and the loan holds up.

A realistic example loan schedule

Below is an illustrative owner loan to show how the pieces fit — the amount, a market rate, a term, and how each payment splits. These are example figures only, not a quote or a recommendation of any specific rate.

Notice what the table deliberately does not do: it does not multiply a factor against the principal to produce a fixed total payback number. An owner loan is a cash-flow arrangement — scheduled payments out of business revenue — not a lump-sum obligation you pre-total on day one. Keep your thinking in monthly-payment-versus-cash-flow terms.

Decision framework: lend your own money, or fund from outside?

The real question is rarely "how" — it is "should I." Lending your own money is cheap and fast, but it concentrates risk: if the business struggles, your personal reserves are trapped inside it. Here is how underwriters think about the tradeoff.

An owner loan works best when:

• The need is short, specific, and you can clearly see the cash coming back — bridging a known receivable, covering payroll for a defined gap, or a one-time purchase.
• You have ample personal liquidity beyond the amount, so lending it does not put your household at risk.
• You want to build debt basis (S-corp) or keep the transaction fully in your control.
• The amount is small enough that outside financing fees would outweigh the benefit.

Avoid an owner loan — and look at outside capital instead — when:

• The amount would drain your emergency reserves or retirement savings.
• The need is recurring or the business is not yet reliably cash-flow positive; you would just be feeding an ongoing shortfall with personal money.
• You cannot articulate a concrete repayment source. If you can't underwrite the loan, don't make it.
• You would be lending to cover a problem — declining revenue, mounting obligations — rather than to fund growth. That is the moment to preserve personal cash, not commit it.

When the framework points away from your own pocket, the alternative that fits most small operators is revenue-based funding through a marketplace. Instead of pledging your savings, approval leans on your business's bank deposits and revenue rather than a strong personal credit score. For a fuller comparison of the options, see our business funding guide.

When outside revenue-based funding is the smarter move

If you would rather keep your personal reserves intact, a revenue-based / MCA marketplace is built for exactly the situations where an owner loan is risky. The model is straightforward: a funder advances working capital and is repaid as a small, regular share of your incoming revenue, so the payment flexes with your deposits rather than sitting as a fixed personal obligation.

What makes it accessible to operators who would otherwise self-fund:

• Approval on bank deposits and revenue, not credit. Consistent business cash flow carries the decision. FICO scores around 500+ are commonly workable, which opens the door for owners a traditional bank would decline.
• Funding amounts starting around $10,000, sized to real working-capital needs.
• Speed measured in 24 to 48 hours in many cases, versus the weeks a bank package can take — useful when the alternative was reaching for your own cash because it was the only fast option.
• A marketplace, not a single lender. One application is shopped to multiple funders, which improves your odds of a fit without pledging personal assets.

No responsible funder guarantees approval, and terms depend on your revenue picture. But when the decision framework says "don't lend your own money," this is usually the cleaner path: your savings stay yours, and repayment is tied to the same revenue that would have supported the loan anyway.

Mistakes that get owner loans re-characterized

• No note, or a backdated one. The single most common and most damaging error. Write it when the money moves.
• Zero or below-market interest. Triggers imputed-interest rules and signals to the IRS that this was equity, not debt.
• Ignoring the repayment schedule. Missing payments — or never taking any — is strong evidence the "loan" was really a contribution or a distribution.
• Commingling. Paying business expenses from your personal account, or personal expenses from the business, blurs the line the note is supposed to draw.
• Booking it as income or as equity. Principal is a liability. Recording it wrong overstates income or hides the debt you're owed.
• Lending money you actually need. Not a tax mistake, a survival one. If clawing the money back would hurt, you funded from the wrong source.
