You’re passionate about your product, so it’s only natural to back it with your own money. And the mechanics seem simple enough – transfer funds from your personal account to the company account and pay yourself back later.

That’s roughly right. But the details matter, and getting them wrong can cause real headaches when investors come into the picture or tax time rolls around.

Why Record-Keeping Matters More Than You Think

Before investors are involved, if your startup has enough cash to repay your loan, great – pay it back and move on.

Once you’re raising capital, it gets more complicated. Investors put money into a startup to fund future growth, not to repay founder loans. If you still have loans outstanding when you’re raising, investors can ask you to write them off entirely. And if they don’t, they’ll typically wrap the loan in agreements that prevent repayment until you hit certain revenue or capital milestones, or until exit.

Either way, keeping clean records of any money you put into your company matters for several reasons:

• Investors want to see that your books are in order and you’re organised
• It demonstrates that you’ve backed yourself, which investors like to see
• It’s important if you’re applying for the R&D Tax Incentive – one of the most valuable sources of non-dilutive funding for Australian startups
• It makes everything easier as you grow – the last thing you want is to reconstruct months of transactions from raw bank records during due diligence

How to Record Founder Loans

If you’re putting in a lump sum, have a loan agreement in place that covers interest rates (if any) and repayment terms. Startup-friendly lawyers like LegalVision or Sprint Law can help you pull one together quickly and affordably.

For ongoing record-keeping:

• If you’re using a spreadsheet: Record the initial loan amount and date, then log every repayment with the amount and date.
• If you’re using Xero: Set up a loan liability account to record founder loans and repayments. This keeps everything clean and auditable.

How to Record Founder Expenses

It’s common for founders and early employees to use personal funds or credit cards to cover company expenses – especially before the company has its own bank account. This is effectively another form of loan to your startup and should be recorded the same way.

• If you’re using a spreadsheet: Record each expense with the amount, what it was for and the date, along with any repayments back to yourself.
• If you’re using Xero: Set yourself up as a supplier – something like “Mary Jones Expense Report” – then enter expenses as supplier bills and pay them to the loan account. Dext integrates well with Xero here, letting you snap and send receipts from your phone so they flow straight into your accounts without the manual entry.

Is Founder Money an Investment or a Loan?

It can be either. Lump sum contributions can be structured as equity investment rather than debt, in the same way any shareholder would invest. But most founders simply transfer cash and sort out the classification later – which is workable, as long as you record it either way.

Even if investors ask you to write off the loan down the track, having a clear record of what you’ve put in shows you’ve been backing your own company. That matters to investors.

What Are the Tax Implications?

If you’re loaning money to your startup, there are a few things to know at tax time:

• Your company can generally claim a deduction for any interest expense on the loan
• You’ll need to declare that interest as personal income in your own tax return
• If you repay the loan to yourself, that’s not treated as personal income – no tax implications
• If the loan is forgiven or written off, the tax treatment can get complex and you’ll want specific advice

Can Your Startup Lend Money Back to You?

Yes, your startup can temporarily loan money to you as a founder – but you need to record it properly and try to avoid having net loans outstanding to founders at the end of the financial year. If you do, the ATO’s Division 7A rules can apply, which treat the loan as assessable income – meaning you’ll pay income tax on it.

It’s a detail that catches founders off guard, so it’s worth being across it before the end of the financial year rather than after.
