Tax calculation spreadsheet for self employed individuals
Some years ago, I made a spreadsheet for myself so that I wouldn’t have a nasty shock when I did my tax return. I shared it with a few friends and on Twitter and it went mildly viral. It has a cashbook, travel and milage calculator and now includes sections on including PAYE income and Covid related payments eg SEISS.
This is a free to use resource and there are clear instructions on the front page on how to download it so please don’t contact me asking for permission to access it! Links to the previous and current tax years below:
