As the 2023/24 tax year comes to a close, thousands of UK workers and pensioners are receiving urgent tax calculation letters from HMRC. These letters, known as Simple Assessment Letters or Tax Calculation Letters (P800s), inform taxpayers whether they owe additional tax or are due a refund.
Ignoring these letters could lead to missed refunds, unexpected tax bills, or even penalties for late payments.
Who Will Receive an HMRC Tax Calculation Letter?
HMRC has confirmed that three specific groups of taxpayers will receive Simple Assessment Letters:
- Individuals who owe Income Tax that cannot be deducted through Pay As You Earn (PAYE).
- Taxpayers who owe HMRC £3,000 or more.
- State Pension recipients who need to pay tax on their pension income.
These letters are automatically issued to anyone who owes tax that cannot be collected through a tax code adjustment or Self Assessment registration.
What Is a Tax Calculation Letter (P800)?
A P800 tax calculation letter is issued when HMRC identifies a tax discrepancy. This usually happens when:
- An individual is owed a tax refund due to overpaid tax.
- Someone owes additional tax due to incorrect tax codes.
- A taxpayer has multiple employers in the same month.
- A pensioner starts receiving a workplace pension.
- Someone begins receiving Employment and Support Allowance (ESA) or Jobseeker’s Allowance (JSA).
What Should You Do If You Receive an HMRC Simple Assessment Letter?
If you receive a Simple Assessment Letter, follow these steps:
1. Check the Information Carefully
- Review all details in the letter and compare them with your records.
- If you spot errors, contact HMRC within 60 days to dispute the calculation.
2. Understand Your Tax Payment Obligation
- If you owe tax, you must pay by the deadline stated in the letter.
- If you are due a refund, HMRC will automatically issue the repayment to your bank account or by cheque.
3. Be Aware of Payment Deadlines
- If you received your letter before 31 October 2024, your tax payment must be submitted by 31 January 2025.
- If your letter was sent on or after 31 October 2024, you must pay within three months of the letter’s date.
