About

I'm Sam Brown, a software developer working on UK payroll software. I'm not an accountant and not a tax adviser.

The posts here are things I had to understand properly to build against HMRC's specs, written up the way I'd explain them to a colleague. Real figures, worked examples, the primary source linked, and the bits I worked out myself flagged so you can check them.

Nothing on this site is tax or legal advice. Check GOV.UK or a qualified adviser for anything that affects you or your business.
