When you move home in the UK, one crucial step is notifying HM Revenue & Customs (HMRC) of your new address. HMRC uses your address to send important tax information, benefit notices, tax credits, and communication about National Insurance and self-assessment. Failing to update it promptly can lead to missed mail, late penalties, or even administrative complications. Here's how to update your address safely and efficiently.
Why Updating Your HMRC Address Matters
HMRC processes many sensitive matters including:
- Self Assessment tax returns
- Child Benefit and tax credits
- State Pension and National Insurance correspondence
- PAYE and refunds
If your address is outdated, correspondence could be delayed or lost and in some cases, HMRC charges penalties—especially if postal notices are returned undelivered. ([turn0search0], [turn0search12])
Methods to Update Your Address
Online (Recommended)
Probably the quickest way is via your HMRC personal tax account:
- Log in via Government Gateway or HMRC app
- Go to “Personal details” → “Change your address”
- Verify identity and input new address
HMRC recommends using the online service—you can even use the official HMRC app for easy access. Many users report it takes under 5 minutes. ([turn0search6])
By Post or Phone
If you prefer, you can write to HMRC including your old and new address, National Insurance number, UTR if applicable. Alternatively, HMRC’s helplines are available: phone lines are busiest in the afternoon, so calling before 10 am or after 4 pm is ideal. ([turn0search20])
When Should You Notify HMRC?
Best practice is to notify HMRC within 30 days of moving. This ensures correspondence—such as Self Assessment tax returns or maintenance letters—reach you in time. If you fail to notify, you may receive penalties under self-assessment rules or delayed benefits. ([turn0search18], [turn0search8])
Who Needs to Update?
- Anyone paying Income Tax or National Insurance
- Self Assessment taxpayers
- Recipients of State Pension, Child Benefit, or tax credits
- Self‑employed or employers managing PAYE
If you're employed or self-employed, ensure both your personal and business addresses are updated separately. Your employer may not notify HMRC automatically. ([turn0search12])
Common Pitfalls to Avoid
- Typos in postcode or house number
- Updating only some parts—ensure both personal and business details are correct
- Using third‑party “address change” services that charge unnecessary fees
Always use the official gov.uk or HMRC app to avoid scammers. ([turn0search10])
How Long Does It Take?
Once submitted online, the update is reflected in your profile instantly. However, processes like Child Benefit or state pension updates may take up to 15 working days. ([turn0search4])
Checklist Before Submitting
- Have your NI or UTR ready
- Use verified HMRC login or app
- Double-check the address visually
- Attempt online first, then phone or post only if needed
