Going freelance: the money side, step by step

Step one: build a starting buffer before you leap

Freelance income is irregular, especially in the first few months while you build a client base. Most people are better off with three to six months of essential expenses saved before going full-time freelance, rather than starting from zero.

A savings calculator can help you work out how much to put aside each month in the run-up to going freelance, based on how many months of buffer you're aiming for and your timeline.

Step two: decide sole trader or limited company

Most people starting out choose to be a sole trader because it's simple to set up and has less admin. A limited company adds legal separation and can be more tax-efficient at higher income levels, but comes with more paperwork, including annual accounts and Corporation Tax returns.

There's no universally right answer. It depends on your expected income, how much admin you're prepared to take on, and whether you want the liability protection a limited company offers.

Step three: register with HMRC

If you're a sole trader, you must register for Self Assessment by 5 October following the tax year you started trading. If you set up a limited company, you register the company with Companies House, then separately register for Corporation Tax within three months of starting to trade.

Missing these registration deadlines can trigger penalties even before you've filed anything, so it's worth putting the date in your calendar as soon as you take your first paid piece of work.

Step four: open a separate business account

You're not legally required to have a separate bank account as a sole trader, though it's required for a limited company, but it makes record-keeping vastly simpler either way. Mixing personal and business transactions in one account is one of the most common causes of a messy tax return.

A separate account also makes it much easier to see, at a glance, how much of your balance is actually yours to spend versus set aside for tax.

Step five: work out what to set aside for tax

As soon as money starts coming in, start setting aside a percentage for tax rather than waiting until the return is due. A self-employed tax calculator gives you a reasonable estimate of your likely Income Tax and National Insurance based on your expected profit for the year.

A commonly used starting point is 25-30% of income, adjusted upward if you expect to be a higher-rate taxpayer or you're VAT registered and collecting VAT on top of your fees.

Step six: sort out invoicing and payment terms

Decide your standard payment terms upfront, commonly 14 or 30 days, and put them on every invoice along with clear details of what's being charged for. Chasing late payment is far easier when the terms were agreed in writing from the start.

Consider whether you need to register for VAT, currently required once your rolling 12-month turnover passes £90,000, and build that into your invoicing templates in advance if you're approaching the threshold.

Step seven: think about insurance and pensions early

Many freelancers need professional indemnity or public liability insurance depending on their field, and it's worth checking before you take on your first client, not after something goes wrong. There's no employer pension contribution when you're self-employed, so any pension saving is entirely down to you.

Setting up even a modest regular pension contribution from the start builds a habit that's much harder to start later once other spending commitments creep in.

Step eight: keep records as you go

Log income and expenses regularly rather than trying to reconstruct a year's worth of transactions the week before your tax return is due. Simple spreadsheet templates or basic accounting software both work, as long as you're consistent.

Good records also make it much easier to spot cash-flow problems early, before they become serious, since you can see trends rather than just a single bank balance.

Step nine: plan for your first tax bill being bigger than expected

Your first Self Assessment bill can include payments on account towards the following year, meaning it's often around one and a half times your actual tax liability for the year just gone. This catches a lot of new freelancers off guard.

Setting aside a higher percentage than you think you need in year one, and adjusting downward later once you understand your actual pattern, is a sensible way to avoid a shortfall.

Common questions

How much should I save before going freelance?

Three to six months of essential living costs is a common target, though it depends on your industry and how quickly you expect income to become steady. A savings calculator can help you plan a monthly saving target to reach that buffer before you start.

Do I need to register as a business straight away?

You need to register for Self Assessment as a sole trader by 5 October following the tax year you started trading, or register a limited company with Companies House if you go that route. Don't wait until your first tax return is due.

How much tax should I set aside from freelance income?

A common starting estimate is 25-30% of income, adjusted higher if you expect to be a higher-rate taxpayer or are VAT registered. This is a rough guide only; a self-employed tax calculator will give you a more tailored figure.

Is a limited company always better for tax?

Not always. It can be more tax-efficient at higher income levels but comes with more admin and costs, including annual accounts and Corporation Tax returns. Many people start as sole traders and switch later if their income grows significantly.

What's the biggest financial mistake new freelancers make?

Spending income as if it's all take-home pay, without setting aside money for tax as they go. This often leads to a painful shock at the January Self Assessment deadline, particularly once payments on account are included.
