FAQ

Is this page telling me exactly how to pay HMRC?

No. It helps you estimate the likely tax amount. For filing/payment steps, follow GOV.UK guidance.

Because UK tax rules have many scenarios. This MVP is intentionally simplified and transparent about assumptions.

Can I share the estimate with my accountant?

Yes. Use the share link; it stores inputs in the URL. Avoid sharing sensitive information.
