UK Sole Trader Tax Template 2026/27 Tax Year

A professional Microsoft Excel spreadsheet that calculates your complete UK tax position automatically, all year long. Built by a qualified accountant on confirmed 2026/27 UK tax rates.

Most sole traders have no idea what they will owe in January until December at the earliest.

By then it is too late to plan. Too late to spread the cost. Too late to do anything except find the money or borrow it. The savings either are or are not there, and if they are not, January becomes a crisis instead of a transfer.

It does not have to work this way. The sole traders who never have a January problem share one habit. They know their number from April onwards and save toward it every month.

This template gives you that visibility from day one of the tax year.
