Lending money to your own business

An owner who puts money into the company has to decide whether it is capital or a loan. If it is a loan, it needs to look like one from the first day.

Why a documented loan beats an undocumented transfer

When an owner moves $50,000 from a personal account into the business account, the transfer itself says nothing about what it is. It could be a capital contribution, which increases the owner’s stake and is repaid only when the company distributes profits or is sold. Or it could be a loan, which the company owes back on fixed terms with interest, ahead of any return to owners.

The two are treated very differently, and the difference is decided by evidence. If the IRS, a bank, or a buyer looks at the books and sees a transfer with no note, no rate, no schedule, and no payments, they will tend to treat it as equity, whatever the owner intended. The consequences follow from that.

  • Repayment. Money the company pays back on a documented loan is repayment of principal, not income to the owner. Money paid out against an undocumented advance may be treated as a distribution or, in some cases, as wages, with the tax that goes with that.
  • Interest. Interest on a genuine loan is generally deductible by the company and taxable to the owner. On an advance recharacterized as equity, there is no interest to deduct.
  • Basis and losses. How an owner’s advance is characterized can affect their basis in the company and their ability to use its losses. The rules differ by entity type.
  • Priority. If the company fails, a documented creditor stands ahead of owners. An undocumented advance is usually treated as the owner’s money at risk.

An accountant preparing the return, a bank underwriting a line of credit, and a buyer doing due diligence will each ask the same question: show me the note. Having it is the whole point.

What the note should contain

The company is the borrower and the owner is the lender. The promissory note is signed by an officer of the company, which may be the same person wearing a different hat. That is normal, and it is exactly why the document needs to be complete: it has to stand on its own, without anyone’s memory to support it.

  • The legal name of the company as borrower and the owner as lender.
  • The principal amount and the date it is advanced.
  • A fixed annual interest rate.
  • The term and the repayment schedule: amortizing monthly payments, interest-only with principal at maturity, or a single payment.
  • The maturity date.
  • Whether the loan is secured, and if so by what. Many owner loans are unsecured.
  • What happens on default, including the owner’s right to demand payment.
  • Whether the company may repay early without penalty.

A loan that is meant to be repaid “when the business can afford it” should still have a maturity date. Open-ended terms are one of the signs that an advance is really equity. See what a promissory note is for each clause in detail.

Charge a reasonable rate

A rate of zero is another sign that the advance is not really a loan, and for a corporation it brings in the below-market loan rules of section 7872, which apply to loans between a corporation and a shareholder as well as to gift loans between individuals. The practical floor is the applicable federal rate for the month the loan is made and the band that matches its term.

A rate at or somewhat above the AFR is defensible. A rate far above what the company could get from a bank invites the opposite question, of whether the interest is really a disguised distribution. Somewhere between the AFR and a commercial rate for a business of similar size is the usual answer. On $50,000 at 8% over five years, the company pays about $1,014 a month and about $10,800 in total interest; the loan calculator shows other combinations.

Interest actually paid is income to the owner and must be reported. The company issues the appropriate information return where one is required.

Make repayments through the ledger

The evidence that a loan is a loan is built month by month. Each payment from the company to the owner should be made on schedule, recorded against the note, and split between interest and principal in the way the amortization schedule sets out. The company’s books show a reduction in the loan payable; the owner’s records show interest income.

Skipped payments that are never caught up, or payments that vary with the company’s cash position rather than the schedule, are what an auditor will point to in arguing that the arrangement was equity all along. If the company genuinely cannot pay, amend the note in writing and have both sides sign the amendment, so the record shows a loan being managed rather than ignored.

A loan kept in NoteHouse gives the owner and the company the same ledger, with the schedule, each payment, and the running balance in one place that an accountant can be given access to at year end.

If the business cannot repay

Businesses fail, and owner loans are often the last to be repaid. What happens then depends on how the loan was documented and on the entity type, and this is where the owner should sit down with their accountant rather than rely on general rules.

Broadly, there are three outcomes.

  • The loan is written off. A loan that was genuinely made in the course of the owner’s business may be a business bad debt; one that was not may be treated as a nonbusiness bad debt, deductible only as a short-term capital loss when it becomes wholly worthless. The distinction turns on facts, and the signed note and payment history are the first facts examined.
  • The loan is converted to equity. The owner forgives the debt in exchange for a larger stake, or simply contributes it to capital. This should be documented with the same care as the original loan.
  • The loan is forgiven. Forgiving a debt owed by one’s own company can have tax consequences for the company, which may have income from the cancellation, and for the owner’s basis.

None of these is simple, and the right one depends on the company’s structure and the owner’s other circumstances. The documentation described in this guide does not decide the outcome, but without it the options narrow quickly.

Questions

Can I lend money to my own LLC?
Yes. The LLC is the borrower and you are the lender. Document it with a signed promissory note, a fixed rate, and a repayment schedule, approve it as the operating agreement requires, and record it as a loan payable in the company’s books.
Do I have to charge my company interest?
A loan with no interest is more likely to be treated as a capital contribution, and for corporations the below-market loan rules can impute interest anyway. Charging at least the applicable federal rate is the usual practice.
Is a loan to my business better than a capital contribution?
Neither is better in every case. A loan is repaid on fixed terms and ranks ahead of owners; a contribution increases your stake and is repaid only through distributions or a sale. The choice affects tax, basis, and what a bank or buyer sees. Decide with your accountant and then document whichever you chose.
What if I am the only owner and sign on both sides?
That is common and permissible. It makes the written record more important, not less, because the note is the only evidence of what was agreed. Record a resolution or consent as well as the note itself.
Can the company deduct the interest it pays me?
Interest on a genuine business loan is generally a deductible expense for the company and taxable income to you. Whether a particular loan qualifies, and any limits that apply, depend on the entity and the facts, so confirm with your accountant.
