how to contact hmrc about tax

You can contact HMRC about tax by phone, online, or post, but the fastest route for most people is using your online Personal Tax Account or the main Income Tax / Self Assessment helplines during weekday office hours.

Quick Scoop

If you’re staring at a tax letter or confused by your code and wondering how to actually reach a human (or at least HMRC) , here’s the practical rundown in plain English.

Main ways to contact HMRC about tax

1. Phone – when you need answers now

HMRC has different phone numbers depending on what your tax issue is.

Key lines people use most often:

  • Income Tax helpline: 0300 200 3300 (PAYE, tax codes, tax on savings, Marriage Allowance, tax back on interest).
  • Self Assessment helpline: 0300 200 3310 (tax returns, balancing payments, late filing penalties, payment plans).
  • National Insurance helpline: 0300 200 3500 (NI records, voluntary contributions, gaps).
  • HMRC online services helpdesk: 0300 200 3600 (if you’re stuck logging in or using the website).

Typical pattern:

  • Lines are usually open Monday to Friday, around 8am–6pm (exact hours can change, so check GOV.UK before calling).
  • Avoid phoning at month‑end, Mondays, and near tax deadlines (31 January / 31 July) – wait times can be long.
  • Recent reports show HMRC only answered around two‑thirds of calls in some years, with average waits over 20 minutes, so don’t be surprised if you’re on hold.

Accessibility:

  • If you have hearing or speech difficulties, you can use Relay UK by dialling 18001 followed by the HMRC number, or use textphone variants HMRC publishes.

What to have ready before you call :

  • National Insurance number.
  • Unique Taxpayer Reference (UTR) if you’re in Self Assessment.
  • Details from any HMRC letter (reference, tax year, amounts).
  • Your income figures or tax return to hand so you can answer security questions.

2. Online – usually the quickest overall

HMRC is nudging everyone towards digital, and for a lot of everyday tax admin it genuinely is the fastest route.

Main options:

  • Personal Tax Account (via GOV.UK): lets you
    • Check your tax code and PAYE details
    • View and update personal details
    • Check if you’re due a tax refund
    • See National Insurance record and State Pension forecast
    • Send secure messages in some cases
  • Secure messages / online forms:
    • For non‑urgent queries, you can send a secure message once logged in, or use specific HMRC online forms for things like complaints or adjustments.
* This creates a written trail you can refer back to.
  • Online services helpdesk:
    • If you’re locked out of your account, your activation code hasn’t arrived, or something on the site keeps erroring, the Online Services helpdesk is there to sort technical issues.

Pro tips:

  • Take screenshots of confirmation pages and any key messages you send or receive.
  • Use the official HMRC / GOV.UK websites only – never follow email links asking for bank details.

3. By post – when it has to be in writing

HMRC still works a lot by letter, and some things are better (or only) done in writing.

  • You can send letters, forms, and tax returns by post, usually to the address shown on the latest HMRC letter or on GOV.UK for that tax area.
  • Always include:
    • Your full name and address
    • National Insurance number
    • UTR (if Self Assessment)
    • The tax year(s) you’re writing about
    • Any reference numbers from HMRC letters

How to write an effective HMRC letter:

  • Use a clear subject line – for example: “Self Assessment – 2024/25 – Request to amend tax return – UTR 12345…”
  • Keep it factual and organised, not emotional.
  • Number your questions or points so it’s easy for them to respond point‑by‑point.
  • If sending original documents, consider recorded delivery and keep copies.

Be aware:

  • HMRC openly acknowledges that post can be slow, and response times vary depending on the type of case.

Which method should you use?

Here’s a simple way to choose:

[4][3] [1][3] [10][3] [4][1] [3][4][1]
Situation Best contact route
Quick question about tax code or PAYE Income Tax helpline or check code in your Personal Tax Account.
Problem with Self Assessment bill, deadline, penalty Self Assessment helpline, with UTR and figures ready.
Technical issue logging in or using HMRC website HMRC Online Services helpdesk phone number.
Non‑urgent query where you want a paper trail Secure message / online form via GOV.UK account.
Formal complaint, complex dispute, or sending evidence Letter by post to the address shown on GOV.UK or your HMRC letter.

Forum‑style reality check (what people are saying lately)

Recent commentary and articles about HMRC customer service point out that getting through by phone has become harder, with long waits and many calls going unanswered.

You’ll see a lot of stories along the lines of:

“On hold for 40 minutes, cut off, called back, same again…”

Because of that, there’s a bit of a “2020s survival strategy” theme in tax forums:

  • Try online first: Personal Tax Account or online forms whenever possible.
  • Call early in the day and avoid peak dates around the Self Assessment deadline.
  • Keep your own log: dates and times of calls, who you spoke to, and what was agreed.

Practical checklist before you contact HMRC

Before you pick up the phone, write a letter, or log a query online, run through a quick checklist:

  1. Gather ID details
    • National Insurance number
    • UTR (if you have one)
    • Full name, address, date of birth
  2. Collect documents
    • Recent payslips / P60 / P45
    • Your latest tax return and calculation
    • Any HMRC letters or penalty notices
  3. Decide how urgent it is
    • Payment deadline or enforcement letter: call by phone, then follow up in writing if needed.
 * General query or correction: online message or letter may be fine.
  1. After contact
    • Note down the date/time, what you were told, and any reference numbers.
 * Save screenshots or copies of online submissions and confirmations.
