Side hustle to full-time: how to fund the leap without betting the house

The day you resign to run your own business is one of the biggest decisions you’ll make. It’s exciting and terrifying in equal measure. It’s also a financial decision with specific numbers behind it, and the founders who make the leap well usually worked those numbers out months in advance.

What numbers should I know before I quit?

Four figures matter most:

Number	How to work it out	Why it matters
Personal break-even	Your monthly living costs, plus tax on what you’ll pay yourself	What the business must provide each month
Business contribution	Monthly revenue minus the costs of producing and selling	What the business can actually pay out
Runway	Personal savings ÷ the shortfall between the two above	How long you can go before it has to work
Growth from extra hours	What doubling your time would realistically add	Whether full-time actually changes the numbers

The last one is often skipped. Going full-time only makes financial sense if your extra hours produce extra revenue. If the bottleneck is demand rather than time, quitting won’t solve it.

Should I borrow to replace my salary?

This is the trap to avoid. If a business can’t yet pay you, borrowing to cover your salary means it now has to cover both your pay and a loan repayment. That makes the maths harder, not easier.

Funding works much better when it’s used to grow revenue:

• Stock for a product that keeps selling out.
• Equipment that lifts output or quality.
• Marketing for a channel you’ve already tested.
• A website or system that removes a bottleneck.

Your personal runway — savings you set aside before resigning — is what covers your living costs while the business grows into paying you. Keep it separate from business cash.

How do lenders see the transition?

Business funding is generally assessed on the business’s own trading. That means the months before you resign matter a lot. If your side hustle has a run of steady revenue through a dedicated business account, it looks the same to a lender the day after you resign as the day before.

What changes is your personal position. If a lender asks you to guarantee a facility, or you’re using property as security, having left a salary may be relevant. That’s why some founders explore funding options before they resign, while both their business statements and their personal finances are stable.

What tax changes come with going full-time?

A few things tend to arrive around the same time:

• GST registration. If your GST turnover reaches $75,000, the ATO expects registration within 21 days. See the GST milestone page.
• Business losses. If the business makes a loss in a year, non-commercial loss rules can limit whether you offset it against other income. For individuals, the ATO applies an income requirement of under $250,000, plus four tests, including assessable business income of at least $20,000.
• Structure. As income grows, many founders consider moving from sole trader to company. See sole trader to company.
• Paying yourself. As a sole trader you draw from profits; as a company director you may be paid wages or dividends. Your accountant can help plan it.

Illustrative example: a leap timed properly

Illustrative only. A physiotherapist runs an online store selling recovery products in the evenings. Over 12 months, the store’s monthly contribution has grown to about $4,800. Her living costs are about $5,500 a month after tax. She spends 15 hours a week on the store and turns down wholesale enquiries for lack of time.

She saves six months of living costs before resigning. She estimates that going full-time would let her take on two wholesale accounts, lifting monthly contribution to around $8,000 within four months. To fund stock for those accounts, she explores a facility sized on her store’s trading history while she’s still employed. The loan funds growth; her savings fund her. Neither has to do both jobs.

What if it doesn’t work?

Every good plan includes a fallback. Decide in advance what would tell you the leap isn’t working — revenue below a certain level after a set number of months, for example — and what you’d do: part-time work, contracting, or scaling back. Having that line drawn in advance makes it easier to take the risk in the first place.

What should I set up before my last day at work?

A short checklist for the months before you resign:

• Separate accounts for business income and costs, plus a tax account.
• A personal runway account holding several months of living costs, kept apart from the business.
• Insurance that no longer comes with your job — such as income protection or health cover — reviewed and sorted.
• Super contributions, which your employer used to make, planned from the business side.
• A 12-month forecast showing revenue, costs, what you’ll pay yourself and any repayments.

Doing this while you still have a salary is far less stressful than doing it after.

Take the leap with numbers on your side

If you’re preparing to go full-time and want to understand your funding options before you hand in your notice, let’s have a chat. Enquiring won’t touch your credit file, your details stay with one real person rather than being passed around lenders, and we’ll call to talk through your plan. Please enter accurate figures on the form — revenue, months trading and any property — so the first option we raise is one that fits.
