One habit that makes the biggest difference: treat tax and cash as “not yours” The single best financial habit in year one is ring-fencing money the moment it lands: VAT (if registered),PAYE/NIC (if you’ve got staff),and a running pot for Corporation Tax or Self Assessment. Too many new businesses look profitable on paper but get caught out when the first big tax bill hits, especially if customers pay late or you’ve had a strong quarter and then a quiet one.
A practical way to do it is to open a separate savings account and sweep a set percentage of every incoming payment straight across. That turns tax into a routine cash movement rather than a scary deadline. It also forces better pricing decisions early on, because you quickly see what’s actually left after tax and costs.
A simple rule of thumb many UK small businesses use:
- Ltd company: move 20–25% of net profit across monthly for Corporation Tax (adjust once you’ve got real numbers)
- Sole trader/partnership: move 25–35% of profit across for Income Tax/Class 4 NIC (higher if you’re heading into higher-rate)
- VAT registered: treat VAT as a pass-through and move it out as soon as you’re paid
Pair that with a weekly 15-minute “cash check” (what’s in, what’s due out, what’s overdue) and the business stops lurching from invoice to invoice. It’s boring, but it prevents the classic first-year crunch: good sales, empty bank account, and a tax bill you can’t comfortably cover.
