How to Register in the HMRC App (Step-by-Step Guide for Beginners)

Many young people who start working in construction ask me the same question:

“How do I get my UTR in the HMRC app?”

Before you can get your UTR (Unique Taxpayer Reference), there’s one essential thing you need to do first - register with HM Revenue & Customs (HMRC).

In this guide, I’ll walk you through the exact steps to register in the HMRC app as a sole trader. Follow them carefully - each step is important.

Step 1: Download the HMRC App

To begin, you need the official HMRC mobile app

You can download it from:

• Google Play Store (for Android)

• Apple App Store (for iPhone)

Search for “HMRC” and install the official app from HM Revenue & Customs.

This app will later allow you to:

• View your tax information

• Check your National Insurance

• Access your UTR once it’s issued

Step 2: Open the App and Start Registration

Once installed:

1. Open the HMRC app

2. Tap “Sign in”

3. Choose one of the options:

   1. Government Gateway

   2. GOV.UK One Login

   3. Create new sign in details

If you’ve never had an HMRC account before, select:

👉 “Create new sign in details”

Step 3: Enter Your Email

You’ll now need to:

1. Enter your email address

2. Receive a verification code from HMRC

3. Enter the code to confirm your email

Step 4: Create a Secure Password

Your password must be strong. It should:

• Be at least 12 characters long

• Include:

  • Uppercase letter

  • Lowercase letter

  • Number

  • Special character

Step 5: Create Your Government Gateway ID

After registration, you will receive your Government Gateway User ID (12 digits).

⚠️ Important:

Save this ID somewhere safe, you will need it every time you log in.

Step 6: Set Up Security Verification

You must enable 2-factor authentication (2FA).

Options include:

• SMS code

• Authentication app

• Voice call

Each time you log in, HMRC may send you a security code for protection.

Step 7: Verify Your Identity

To complete your registration, HMRC may ask you to confirm your identity.

You might need:

• UK passport

• UK driving license

• Pay-slips

• Credit history questions

• National Insurance number

Some users may also verify their identity using the GOV.UK ID Check app.

Step 8: Create Your Personal Tax Account

Once everything is verified, your Personal Tax Account will be created automatically.

Inside the app, you’ll be able to see:

• Your tax code

• National Insurance

• Income history

• Self Assessment services

• Your UTR number (once registered)

Registering in the HMRC app is the first and most important step if you want to work as a sole trader, especially in construction.

Take your time, follow each step carefully, and make sure your details are correct.
