Self-employed money guide.

Going self-employed swaps a steady payslip for freedom — and for a pile of financial responsibilities that an employer used to quietly handle for you. Nobody's deducting your tax, paying into your pension, or covering you when you're ill. Get a few habits in place early and self-employment is liberating. Ignore them and the January tax bill arrives like a wrecking ball. Here's what to actually do.

Reserve tax the moment money lands

The single biggest self-employed mistake is spending money that isn't really yours. When a client pays you, a chunk of that is the taxman's — you're just holding it. The fix is simple and non-negotiable: the moment money comes in, move a percentage straight into a separate tax savings account and don't touch it. A rough starting point for many is 20–30% depending on your earnings, but work out your own rate. Do this and the tax bill is already sitting there waiting; skip it and you're borrowing to pay HMRC.

Separate business and personal money

Open a separate account for the business, even as a sole trader. Money in, expenses out, tax reserved — all in one place, away from your personal spending. It makes your tax return vastly easier, shows you what you're really earning, and stops the blur where business income feels like spending money. It's the single best bit of admin hygiene for the self-employed.

You have no employer pension — so be your own

As an employee, auto-enrolment quietly built your pension. Self-employed, nobody does — and self-employed people are among the most under-pensioned in the country as a result. You still get tax relief on pension contributions, so a personal pension is very much worth setting up. It's easy to say ‘later’ when income is lumpy, but even modest, regular contributions started early beat a panic in your fifties.

You have no sick pay either

No work often means no income, with no employer sick pay behind you. That makes two things more important for the self-employed than for anyone else: a solid emergency fund (lean towards the larger end — six months or more, given lumpy income), and seriously considering income protection. You are your own safety net now, so build one deliberately.

Manage the lumpy cashflow

Irregular income is the defining challenge. The trick is to smooth it yourself: in good months, don't inflate your spending — build a buffer that carries you through the quiet ones. Pay yourself a consistent ‘salary’ from the business account and leave the rest to cover the lean patches, the tax and the pension. Treating your business account like a tap you open fully every month is how good years still end in stress.

Self-employment rewards the organised. Reserve your tax, separate your money, build your own pension and buffer, and plan for the lumpiness — and you get the freedom without the fear. A good accountant (like Buzz Accounting) earns their fee here many times over; coaching helps with the money habits that sit alongside it.
