Going freelance for the first time: a practical financial checklist

The decision to go freelance is usually made in a moment of clarity — a project you’re excited about, a difficult employer, or simply the realisation that you could earn more working for yourself. The financial setup that needs to follow that decision is less cinematic but just as important. Miss a step in the first few months and you can spend years untangling the consequences.

This checklist covers everything you need to do financially in your first 90 days as a freelancer — in the order you should do it.

Week one: the non-negotiables

• Register as self-employed with HMRC. Do this at gov.uk as soon as you start trading. You have until 5 October of the second tax year, but registering early means you won’t forget and won’t face a fine.
• Open a dedicated business bank account. Use it exclusively for business income and expenses from day one. Mixing personal and business finances is the single most common mistake new freelancers make.
• Set a day-rate or project rate. Research what others in your field charge. A good starting point: your previous salary divided by 220 working days, then multiplied by 1.3 to account for tax, unpaid admin time, and holiday.

Month one: set up your systems

• Start a tax reserve immediately. Set aside 25–30% of every payment you receive. This covers Income Tax and National Insurance contributions. If you have a good year, you’ll have more than you need — that’s a good problem. Vaulta’s tax reserve feature does this automatically on every incoming payment.
• Create an invoice template. Include your name, address, bank details, a unique invoice number, payment terms, and a clear description of the work. Send it the same day you complete the work.
• Start tracking expenses. Keep receipts for everything work-related. A simple spreadsheet works, but dedicated software like Vaulta’s expense categorisation makes it significantly less painful.
• Check your National Insurance record. Log in to your personal tax account at gov.uk and check you have no gaps in your NI record. Gaps affect your State Pension entitlement and are cheap to fill now, expensive to fix later.

Month two to three: the longer-term foundations

• Build a three-month emergency fund. Freelance income is irregular. Three months of essential expenses in an easy-access account means one slow month doesn’t derail everything.
• Consider professional indemnity insurance. If you give advice, create work that a client relies on, or handle data, PI insurance covers you if something goes wrong. It’s often required by larger clients before they’ll sign a contract.
• Think about a pension. Nobody else is paying into yours anymore. Even a small monthly contribution to a SIPP (Self-Invested Personal Pension) starts compounding immediately and is tax-deductible as a business expense.
• Set a monthly salary. Decide how much to pay yourself from your business account each month and stick to it. A predictable personal income makes personal budgeting possible even when client payments are irregular.
