A Practical Guide for Expats, Contractors & UK Leavers
Leaving the UK permanently or for full-time work abroad? Don’t forget to file Form P85 with HMRC. It’s a crucial step for ensuring your tax affairs are in order—and getting a possible refund.
Unfortunately, many people make avoidable mistakes that delay processing or even lead to penalties.
Here’s how to avoid those pitfalls—and how our team at AB & CO Accounting & Tax Services limited can make the process stress-free.
What Is Form P85 and Why Does It Matter?
Form P85 is used to tell HMRC that you’re leaving the UK—either permanently or for full-time work abroad lasting at least one full tax year.
Why it’s important:
- You may be entitled to a tax refund
- It helps HMRC update your residency and income status
- It avoids complications with future self-assessment returns or National Insurance
Common Mistakes People Make on Form P85
Even small errors can cause big delays. Here are the most common issues we see:
1. Inaccurate Personal Details
Make sure your name, National Insurance number, and contact info match exactly with HMRC’s records.
2. Incorrect Date of Departure
Your date of leaving must be accurate and match any supporting documents.
3. Missing P45
A P45 from your employer is critical—don’t submit the P85 without it.
4. Not Closing Self-Assessment
If you’re self-employed, don’t forget to formally close your self-assessment account. Leaving it open can trigger late filing penalties later.
5. Misreporting Residency Status
Your residency affects your tax treatment—mistakes here can lead to incorrect assessments.
6. Incomplete Income Info
Be sure to list all income sources—from employment, rental, dividends, etc.—before and after leaving the UK.
7. Wrong or Outdated Address
Use a valid address for post-departure correspondence, especially if expecting a refund cheque.
