Before you start
- An email address you can open now. EasyTaxer emails you an activation code, and a six-digit code each time you sign in.
- Your National Insurance number. EasyTaxer asks for it the first time you select Connect to HMRC.
- Your Government Gateway user ID and password. You type them on HMRC's website, never into EasyTaxer.
Steps: the text version of this video
-
Create your account
Here's how to sign up for EasyTaxer and connect it to HMRC. On the sign-up page, tick the box to agree to the Terms and Conditions and the Privacy Policy. Enter your email address, your name, and a password, then select Create account.
-
Confirm your email
EasyTaxer emails you a short activation code. Enter it here to activate your account.
-
Sign in
Now sign in with your email and password. For extra security, EasyTaxer emails you a six-digit code each time you sign in. Enter it to continue.
-
Connect to HMRC
Now select Connect to HMRC. HMRC identifies you by your National Insurance number, so the first time you connect, EasyTaxer asks for it. Enter your number.
-
Save and go to HMRC
Select Save and connect to HMRC. You'll be taken to HMRC's own website to sign in, so EasyTaxer never sees your Government Gateway password.
-
Sign in on HMRC's website
HMRC explains what the software is asking for. Continue, then sign in with your Government Gateway user ID and password.
-
Give permission
HMRC then lists exactly what EasyTaxer may do: view and change your Self Assessment information, and read Self Assessment Assist data. Select Give permission. The permission lasts eighteen months, and you can remove it at any time.
-
You're connected
You're sent straight back to EasyTaxer, now connected. The businesses HMRC holds for you appear in the switcher at the top of the page, and the dashboard shows the next deadline for each one.
What happens next
- EasyTaxer reads the businesses HMRC holds for you and shows the next deadline for each one on your dashboard.
- The permission you gave lasts 18 months, and you can remove it at any time.
