HMRC Personal Tax Account Walkthrough UK 2026: Sign-Up & Use

The HMRC Personal Tax Account (PTA) is your single online portal for everything tax-related. Setting it up takes 15 minutes; once you have it, you can check your tax code, claim refunds, update your address, view your NI record, and do most things that previously required a phone call to HMRC.

If you've never set one up, this guide walks you through it step by step.

Why you should set one up

The PTA replaces 90% of the reasons people previously had to call HMRC. From it you can:

• Check your current tax code and the codes HMRC has on file for each of your employments.
• See your full PAYE income for the current and previous tax years.
• View your National Insurance record including any gaps that need filling.
• Claim a tax refund for emergency tax, expenses, professional fees, etc.
• Apply for the Marriage Allowance (worth up to £252/year per couple).
• Update your address with HMRC.
• Check your State Pension forecast.
• See your P800 letters and respond to them.
• Add or remove benefits in kind (company car, medical insurance) that have changed mid-year.

The PTA is free, secure, and the official channel. Avoid third-party "HMRC tax checker" sites that ask for your personal details and route you to a refund agency for a fee.

Sign-up routes - two paths

HMRC currently offers two sign-up methods:

Path 1 - GOV.UK One Login (newer, since 2024)

GOV.UK One Login is the unified government identity service rolled out from late 2024 onwards. It uses photo ID (passport or driving licence) plus a face match via the GOV.UK ID Check app. Once verified, your One Login works across all government services (HMRC, Companies House, DVLA, etc.).

To set up:

1. Go to gov.uk/personal-tax-account.
2. Click "Sign in to your personal tax account".
3. Choose "GOV.UK One Login" if offered.
4. Provide an email address and verify it.
5. Use the GOV.UK ID Check app (iOS/Android) to scan your passport or driving licence and complete a face match.
6. Set up two-factor authentication.

The whole flow takes about 10-15 minutes.

Path 2 - Legacy Government Gateway + HMRC verification

If you already have a Government Gateway user ID (you've used HMRC online services before, e.g. for Self Assessment), you can use the legacy route:

1. Go to gov.uk/personal-tax-account.
2. Sign in with your Government Gateway user ID and password.
3. HMRC asks identity-verification questions based on your records - typically your National Insurance number plus details from your most recent payslip or P60 (gross pay, tax paid).
4. Set up two-factor authentication if you haven't already.

This route works if you've previously interacted with HMRC online and your records match.

What to check on first sign-in

Once you're in, do these four checks:

1. Current tax code

Look at the "Pay As You Earn (PAYE)" section. It shows your current tax code for each active employment. Cross-check against your latest payslip - they should match. If the payslip shows a different code, your employer's payroll hasn't picked up the latest HMRC notification.

2. Estimated income

HMRC estimates your annual income for the current tax year. If the estimate is wrong (e.g. you got a raise that hasn't filtered through), update it from the PTA - this prevents an over- or under-deduction at year-end.

3. Benefits in kind

Look at the "Company benefits" section. It shows the BIKs HMRC believes you receive (company car, medical insurance, etc.) - these affect your tax code via P11D. If anything is wrong (a car you returned, medical insurance that ended), update from the PTA.

4. National Insurance record

The NI record shows every qualifying year you've contributed. You need 35 qualifying years for the full new State Pension. If you have gaps, see our note on voluntary NI top-ups in our State Pension top-ups guide.

Common claims you can submit

Tax refund for emergency tax

If you've been on emergency tax (W1/M1/X) and HMRC hasn't yet issued a corrected cumulative code, you can request reconciliation from the PTA. HMRC processes the refund automatically - usually within 5 weeks for current-year refunds.

Job-related expenses (P87 equivalent)

Claim relief for uniform laundry, mileage, professional fees, training, working from home (subject to current rules). All can be claimed direct from the PTA - see our expenses tax relief summary.

Marriage Allowance

If you're married/civil-partnered and one of you earns under £12,570, the lower earner can transfer 10% of their Personal Allowance from the PTA. Worth £252/year + backdate to 2022/23. See our Marriage Allowance guide.

Address change

Updating your address from the PTA is faster than the old phone-based method. The change propagates to your employer's payroll within 2-4 weeks via the next P6 notice.

Tax code correction

If you spot a code error (BR on your only job, K-code from a benefit you no longer receive), you can dispute or correct it from the PTA. HMRC issues a corrected P6 to your employer; the new code applies from the next pay cycle.

Why this matters for refund firms

A typical refund firm charges 20-35% of any refund. For a basic-rate £400 emergency tax refund, that's £80-£140 in fees. The same refund via the PTA is free and takes 5 minutes.

Refund firms add value for genuinely complex cases (multi-year CIS, mixed expenses with documentation issues, contested HMRC determinations). For straightforward employment refunds, the PTA is overwhelmingly the right route.

Two-factor authentication - turn it on

The PTA holds enough information to facilitate identity theft. ALWAYS turn on two-factor authentication.

Choose between:

• SMS code to your phone - convenient but vulnerable to SIM swap attacks.
• Authenticator app (Google Authenticator, Microsoft Authenticator, Authy) - more secure, recommended.

Save your backup codes in a password manager. If you lose access, recovering a PTA without 2FA can take 2-4 weeks of paper-based identity verification.

Common sign-up problems

• Identity verification fails - usually because the address HMRC has on file doesn't match the one you entered. Update your address with HMRC by post first (the only way if you can't sign in).
• No Government Gateway access - start fresh with One Login (the new route).
• No passport or driving licence for One Login - fall back to the legacy NI-number-based route.
• Wrong P60 figures - gross pay must match exactly. Check your latest P60 carefully.
