Self-employed? Stop guessing which pounds are actually yours
When you're employed, someone else does the awkward bit. Tax and National Insurance come off before your pay lands, and what reaches your account is yours to spend.
When you work for yourself, every payment arrives looking bigger than it really is. Some of it belongs to HMRC. Some of it belongs to next month, when a client pays late or the work goes quiet. Only some of it is genuinely yours.
In 22 years in finance, the self-employed people I saw struggling were rarely short of income. They were short of a system. Here's the simplest one I know.
Pot 1: Tax (it was never your money)
Every time a client pays you, move a fixed percentage straight into a separate savings account and leave it alone. Your accountant can tell you the right figure for your level of profit; many sole traders start at around a quarter of each payment and adjust from there.
When the January bill arrives, including the first payment on account that catches so many people out, the money is already sitting there. No scramble, no credit card.
Pot 2: Your pay (yes, pay yourself a salary)
Choose a fixed amount to transfer to your personal account on the same day each month, just like a wage. Base it on an average month, not your best one.
Your household budget then runs on a steady number, however lumpy the business income is. That one change takes a surprising amount of stress off the kitchen table.
Pot 3: The buffer (quiet-month insurance)
Whatever is left after tax and your pay stays in the business as a buffer. A sensible first target is two to three months of your salary plus your fixed business costs.
Once the buffer is full, any surplus becomes a decision rather than an accident: a bonus, a pension contribution, or an investment back into the business.
Why now?
Because the tax calendar is getting busier for the self-employed:
7 November 2026: if your 2024/25 qualifying income was over £50,000, you're already in Making Tax Digital for Income Tax, and your second quarterly update (covering 6 July to 5 October) is due.
31 January 2027: the deadline for everyone's 2025/26 Self Assessment return and any tax owed.
April 2027: Making Tax Digital extends to sole traders and landlords with qualifying income over £30,000, bringing many more people into quarterly reporting.
Separate pots won't do your bookkeeping for you, but they make every one of those dates easier, because the money is already where it needs to be.
Set it up this week (about ten minutes)
Add two savings accounts or "pots" to your business banking and name them TAX and BUFFER.
Agree your tax percentage with your accountant and pick your monthly salary figure.
Next time you're paid, split it before you spend a penny.
This is exactly the kind of structure we map out in the Groundwork stage of the EDGE programme and put in place during Execute: simple systems that make the right thing the easy thing.
