Best Sole Trader Bank Accounts UK 2026 - Free and Paid

As a sole trader in the UK, you are not legally required to have a separate business bank account — unlike limited companies, which must have one. However, keeping business and personal finances separate makes your Self Assessment tax return significantly simpler and is strongly recommended, particularly as Making Tax Digital (MTD) expands from April 2026.

From April 2026, sole traders with gross income above £50,000 must keep digital records and submit quarterly updates to HMRC using MTD-compatible software. A business bank account that integrates with accounting software makes this dramatically easier.

Best Free Sole Trader Bank Account UK 2026

Starling Bank is widely rated as the best free business bank account for sole traders. It offers unlimited free UK transfers, free accounting integrations (Xero and FreeAgent), FSCS protection up to £85,000, and a highly-rated mobile app — all with no monthly fee. Cash can be deposited at Post Office counters for a fee.

For sole traders who already use Monzo personally, Monzo Business Lite is the natural second choice — it sits within the same app, keeping personal and business accounts in one place. The free Lite tier is limited compared to Starling, but works well for basic needs.

Sole Trader Bank Account vs Personal Account — Key Differences

Making Tax Digital and Sole Trader Bank Accounts

MTD for Income Tax Self Assessment (MTD ITSA) requires sole traders earning above £50,000 to submit quarterly digital tax updates from April 2026. A business bank account that integrates with HMRC-approved software (Xero, QuickBooks, FreeAgent, Sage) makes this mandatory requirement significantly easier to meet.

Mettle (NatWest's free business account) includes free FreeAgent software — one of the three HMRC-listed MTD-compatible platforms — making it particularly strong value for sole traders who need MTD compliance.
