Government Gateway and MTD: having an account is not the same as signing up
If you're reading this because you couldn't find where to log in for MTD — you're in the right place, just for the wrong reason.
Does having a Government Gateway account mean I'm signed up for MTD?
No. A Government Gateway account is a login. Signing up for Making Tax Digital is a separate action.
What is a Government Gateway account?
It is the front door key to HMRC online. GOV.UK One Login is gradually replacing Government Gateway for new users, but it is still a sign-in route, not MTD registration.
The three steps people confuse
First, create sign-in details. Second, register for Self Assessment if you need to. Third, sign up for Making Tax Digital if your qualifying income means it applies to you.
If you already have a Government Gateway account
Check Self Assessment, check your qualifying income, then use the GOV.UK MTD sign-up service if you need to sign up.
If you don't have a Government Gateway account
Use HMRC's sign-in page, then register for Self Assessment if needed.
A note on accountants — the real ones, not apps
TidGo collects and organises your records. It does not replace your accountant — and it doesn't try to. Real tax responsibility belongs in professional hands.
A good accountant does things no app can: finds reliefs you didn't know existed, spots the things that don't add up, and makes sure you pay what you owe — not a penny more. And if you're due a refund — as many CIS subcontractors are — they'll make sure you get back every penny you're entitled to. Not a penny less.
Clean records from TidGo mean your accountant spends less time hunting through carrier bags and more time doing what you're actually paying them for — looking after your money.
Think of it this way: TidGo tidies the house before the accountant arrives. What they find when they get there — that's their magic, not ours.
We work alongside your accountant. Because a good accountant is genuinely invaluable.
TidGo keeps your records clean and ready — so your accountant can do their job properly. Start free, no card needed →
