Lending Your Own Company Money: How Founders Actually Fund a Startup Properly

New companies almost never start with all the capital they need already sitting in the business bank account — founders routinely cover early costs personally and get the company to "pay them back" later. Done properly, this is a normal, sensible way to fund a startup. Done informally, it becomes exactly the kind of muddled financial history that causes real problems the first time a bank, investor or SARS looks closely at the company.

The two ways to put your own money in

Share capital. You buy shares in the company, in exchange for the money you contribute. This is permanent capital — the company does not owe it back to you as a debt; your return comes through the shares' value and any future dividends, not repayment.

A director's loan. You lend the company money, which the company records as a liability owed back to you, on whatever terms you and the company agree. This is genuinely different from share capital: it is debt, not equity, and it is meant to be repaid.

Most founders use some mix of both — enough share capital to get the company properly capitalised, and a loan account for the flexible, ongoing top-ups that come with actually running a young business.

Why a loan is often the more practical choice

Topping up share capital every time the business needs another injection of cash means issuing more shares each time — a formal process, and one that can complicate the ownership picture if it happens often or if there is more than one shareholder involved. A loan account is simpler to move money in and out of as the business's cash needs change, and repaying a loan does not carry the formalities that a share buyback or a dividend does. This flexibility is exactly why loan accounts are the default mechanism for ongoing founder funding in practice, with share capital typically set at a sensible baseline rather than adjusted constantly.

Doing it properly: what a founder loan actually needs

• A loan agreement, even a simple one — setting out the amount, whether interest is charged, and the terms of repayment. This does not need to be an elaborate legal document for a straightforward founder loan, but it needs to exist in writing, not live only in memory.
• Proper recording in the company's books as a loan account or director's loan account — a genuine liability on the company's balance sheet, distinct from share capital and distinct from the founder's personal finances. This is where informal arrangements most often go wrong: money moves between a founder's personal account and the company's without ever being properly recorded as a loan, leaving no clean record of what is actually owed to whom.
• A decision on interest. The company can pay you interest on the loan, in which case that interest is normal taxable income in your hands and the company treats it as a financing cost, subject to the ordinary rules on deductibility. Many founder loans are simply interest-free, particularly in the early stages, which is a common and generally unproblematic choice for a loan running in this direction — see the important caveat below about the opposite direction.
• Clarity on repayment terms — whether the loan is repayable on demand, on a set schedule, or only once the business reaches a certain point. Vague terms are a common source of disagreement later, particularly if a founder leaves the business or the company's cash position changes.

The important direction to get right: lending TO your company is not the same as your company lending TO you

This distinction matters and is worth stating clearly, because the tax treatment of the two directions is genuinely different. A founder lending money to the company — the subject of this article — does not trigger the deemed-dividend tax rules under the Income Tax Act. The rule that does apply in this space runs the opposite way: where a company lends money to a connected shareholder (the company advancing funds to you, rather than you advancing funds to the company), an interest-free or below-market-rate loan can be deemed a dividend for tax purposes, potentially attracting dividend tax on the value of the interest the company chose not to charge. That rule is relevant if you are ever thinking about drawing money out of the company as a loan rather than a salary or a declared dividend — a different scenario from funding the company in its early days, and one worth a specific conversation with your accountant if it comes up, rather than assuming the rules that apply to one direction automatically apply to the other.

Subordination: when a lender-founder's loan needs to step back

If a company is thinly capitalised or under financial strain, its auditors or a bank assessing it may require a shareholder's loan to be formally subordinated — meaning the founder agrees, in writing, that their loan ranks behind the company's other creditors and will not be called on ahead of them. This is a genuine, common practice in South African company finance, particularly for early-stage companies where founder loans make up a meaningful part of the balance sheet — it is one of the ways a company demonstrates it is not relying on funding that could be pulled out from under other creditors at short notice. If your accountant or auditor raises subordination, it is a normal request in this context, not a sign something has gone wrong.

What this means for exiting or getting repaid later

A properly documented and recorded loan account is a genuine asset the founder holds against the company — repayable according to whatever terms were agreed, and something a founder can point to clearly if they ever leave the business, sell their stake, or simply want to know exactly what the company owes them. An informally tracked flow of money, by contrast, becomes a genuine source of dispute exactly when it matters most: at exit, in a dispute between co-founders, or when a buyer's due diligence asks the company to account for everything on its balance sheet, including what it owes its own founders.

Getting the basics right

1. Decide, for each contribution, whether it is share capital or a loan — and be deliberate about it rather than defaulting to whichever is easiest in the moment.
2. Document a loan properly, even simply, before or as the money moves — not reconstructed from memory a year later.
3. Keep company and personal finances clearly separated in the accounting, exactly as this series has recommended for every other aspect of running a company properly.
4. Ask your accountant about interest, repayment terms and whether subordination is relevant to your specific situation — this is genuinely worth a short conversation rather than a guess.

Sources: general South African company and tax practice regarding shareholder/director loan accounts as distinct from share capital, and section 64E(4) of the Income Tax Act (the deemed-dividend rule for loans made BY a company TO a connected shareholder, at less than the SARS official interest rate) — cited specifically to clarify that this rule does not apply to the reverse direction covered in this article. This is general information, not tax or legal advice — the specific tax and accounting treatment of a founder loan should be confirmed with your accountant before the money moves, not after.

A worked example

A founder registers a company with R1,000 in share capital — enough to get it legally established — and over the next six months personally covers R85,000 in early costs: a laptop, initial stock, a first month’s rent on a small workspace, a website build. Done properly, each of these payments is recorded as a loan from the founder to the company, building up a director’s loan account balance of R85,000, documented in a simple loan agreement stating the loan is interest-free and repayable once the company’s cash flow allows. Eighteen months later, once the business is generating steady revenue, the company begins repaying the loan in instalments — a straightforward, tax-neutral repayment of debt, with a clean paper trail the founder can point to the whole way through.

Compare that to the same R85,000 moved informally: personal card payments for business expenses, occasional transfers from the company account back to the founder’s personal account with no consistent labelling, nothing written down about whether any of it was ever meant to be repaid. A year later, an investor doing due diligence asks a simple question — “what does the company owe its founders?” — and there is no clean answer. Untangling a year of informal flows after the fact, with an investor watching the clock, is a genuinely bad position to be in, and entirely avoidable with the same discipline this series has recommended for every other aspect of running a company.

Frequently asked

Do I need a lawyer to draft a founder loan agreement? For a straightforward, single-founder loan on simple terms, a clear written agreement covering the amount, interest (if any) and repayment terms is usually sufficient without needing an elaborate legal document — the goal is a clear, signed record, not a complex contract. For larger amounts, multiple lenders, or complicated terms, it is worth having an accountant or attorney review it.

Can I charge my own company a high interest rate on my loan to boost my personal income? Interest charged should be commercially reasonable — an artificially inflated rate designed purely to extract value from the company in a tax-favourable way is exactly the kind of arrangement that invites scrutiny. A modest, defensible interest rate (or none at all) is the more common and safer approach for a genuine founder loan.

What happens to my loan account if the company is later sold? A properly recorded loan account is a liability on the company’s books that a buyer will see and account for in the purchase — either repaid to you as part of the transaction, or specifically addressed in the sale agreement. This is precisely why keeping it accurate matters: an unclear loan balance is a common sticking point in company sale negotiations.

Should co-founders each have separate loan accounts, or one combined one? Separate accounts per founder are strongly preferable — each founder’s contribution and repayment history should be individually traceable, both for clarity between the founders themselves and for anyone later examining the company’s finances. A single combined pool makes it far harder to establish who is actually owed what.

What if the company can never repay the loan — can I just write it off? A founder can choose to waive or convert a loan (for instance, into additional share capital) — but this has its own accounting and potential tax consequences depending on how it is structured, and is worth a specific conversation with your accountant rather than an informal decision to simply forget about it.
