How Much to Set Aside for Tax UK 2025–26

Quick answer: UK gig workers should set aside approximately 25–30% of gross income for tax. On £25,000 profit, that is £6,250–£7,500. After mileage and expense deductions, the actual tax bill is typically £3,000–£4,500 — but saving 25–30% ensures you are never caught short.

The Monthly Transfer Method

Every time a platform pays you, transfer the set-aside percentage immediately to a separate savings account. This prevents you from accidentally spending your tax money and ensures you have the full amount ready for the 31 January deadline.
