Taxmax / early prototype
Know what you need before you start.
A short preparation check for UK tax filing. See the credentials and setup steps at the beginning of the journey, before you spend time filling anything in.
Have your details ready, but enter them only into the official HMRC or Companies House service you choose. This page stores checklist ticks in your browser; it does not ask for or receive your credentials.
What are you preparing to do?
Have these ready first
Tick only whether you have each item. Taxmax never asks you to enter an ID, password or authentication code here.
Ask about getting ready
Taxmax answers supported process questions using checked guidance. It cannot calculate tax or give personal tax advice. Do not enter names, tax IDs, email addresses, passwords or financial figures.
