Timing guide

When Will I Get My P800?

Last updated for the 2025/26 tax year

Readers often search for timing because they are waiting for HMRC letters, want to know when P800s get sent out, or want to know how long a refund might take after the tax year ends. This guide explains the broad timing pattern without pretending that every case is identical.

Current GOV.UK guidance says tax calculation letters are sent between June and March of the following tax year, so many readers will not hear anything in April or early May even if they later receive a P800. If you are still waiting to use the official GOV.UK route, that delay can be normal.

HMRC timings can vary, so the aim here is to provide realistic expectations and the right next checks if you have been waiting longer than expected. It is more helpful as a guide to common timing patterns than as a promise of exact dates for every case, especially if you are comparing claim timing, cheque timing or the details on your P800 reference letter.

P800 letters are often discussed more after the tax year ends.
Some refunds move faster than others depending on the case.
It helps to track the tax year, claim date and any follow-up messages.

Typical timing after the tax year

Interest in P800 timing usually rises after the tax year ends because that is when people expect HMRC to review records and issue calculations. GOV.UK says tax calculation letters are sent between June and March of the following tax year, and the online tax calculation service says HMRC calculates everyone's Income Tax between June and November. If you need the wider background, start with the full P800 refund guide.

That is why timing pages often become more important from late spring onwards. People are not only waiting for letters; they are also trying to work out whether their case has been handled yet or whether it is still too early to expect anything.

Typical timeframes (2025/26 tax year)

Based on current GOV.UK guidance, these are the published timeframes HMRC gives for common P800 repayment routes. If you are comparing online claim timing with your own letter, the online claim guide explains the same routes in more detail.

These timeframes are useful as a benchmark, but your own case may still take longer if HMRC needs further checks or if your letter gives a different instruction.

  • Online claim (bank transfer): usually paid within 5 working days.
  • Cheque requested online: can take up to 6 weeks.
  • Letter says HMRC will send a cheque automatically: it should usually arrive within 14 days of the letter date.

Why some people wait longer

Timing can vary because tax records, multiple sources of income, identity checks or other administrative details may need more time. That is why one person may receive a calculation earlier than someone with a more complex record. If you are still unsure what the document means, review What Is a P800? alongside this timing page.

It can also depend on what happened during the tax year. A straightforward employment record may be easier to review than a record involving several changes or updated information arriving later.

  • Your tax record may be more complex than someone else's.
  • HMRC may still be updating information from employers or pension providers.
  • The next step may depend on whether you also need to claim online.

What happens after you claim

If the route for your case involves an online claim, there may be an additional waiting period after you submit it. That is why it helps to keep a note of the day you claimed and any confirmation you received at the time. If you have not claimed yet, use the claim route guide before comparing timeframes.

Without that record, it can be harder to tell whether you are still in a normal waiting period or whether it makes sense to review the situation more closely.

If your refund seems delayed

If you believe you should already have heard from HMRC, review the official route again, check the tax year you are waiting on, and keep a note of any claim or correspondence dates. That makes it easier to understand what stage you are at. If you are worried about copied refund links while you wait, use the official GOV.UK route guide before doing anything else.

The best first response is usually to gather the facts rather than guess. Confirm the year, confirm whether you already made a claim, and confirm that you are comparing your case with the right stage of the process.

Where to go next

Need to double-check a suspicious refund message while you wait?

If you receive an unexpected text, email or WhatsApp message about a P800 refund while you are waiting, treat it carefully. GOV.UK says HMRC will never send notifications of a tax rebate or ask you to disclose personal or payment information by text message.

Common questions

When are P800 letters usually sent?

GOV.UK says tax calculation letters are sent between June and March of the following tax year, so many readers will not receive a P800 in April or early May.

How long does a refund take after a claim?

GOV.UK says online claims are usually paid within 5 working days, while cheques requested online can take up to 6 weeks. If your letter says HMRC will send a cheque automatically, it should usually arrive within 14 days of the letter date.

What if I have been waiting longer than expected?

Review the official guidance, keep your dates handy and make sure you are comparing the correct tax year and claim stage.

Does everyone get a P800 at the same time?

No. Timing can vary, so different readers may hear from HMRC at different stages depending on their records and circumstances.

How do I check my P800 reference number?

Check the reference information on your P800 letter itself and only use it on the official GOV.UK route. If you are unsure where to look, compare your letter with the P800 letter guide first.

Can I claim online if I have not received a letter?

In most cases you should wait for the P800 letter or official HMRC instruction before trying to claim online. The route and timing depend on what your own letter says.
