Timing guide

When Will I Get My P800?

Updated for the 2025/26 tax year. Independent guide, not affiliated with HMRC or GOV.UK.

Quick answer

Most P800 letters for the 2025/26 tax year are sent between June 2026 and March 2027. If you are expecting one, most people receive it between June and October. Online refunds are usually paid within 5 working days. If HMRC sends a cheque automatically, it usually arrives within 14 days.

Is it normal if I have not received my P800 yet?

Before June: this is usually normal.
June to October: most people receive their P800 during this period.
After October: if you still have nothing, check your HMRC account or follow the official GOV.UK route.

HMRC P800 tax calculation letter timeline for the 2025/26 tax year, showing letters issued from June 2026 to March 2027.
A simple timeline showing when HMRC usually sends P800 tax calculation letters for the 2025/26 tax year.

Readers often search for when P800 letters are issued, when P800s get sent out, and when they can expect a refund. HMRC says P800 tax calculation letters are usually sent between June and March of the following tax year, with many people receiving them between June and October.

If you're new to P800 refunds, start with our P800 Refund Guide → for a plain English overview.

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.

Letters sent: June 2026 - March 2027
Online refund: about 5 working days
Automatic cheque: about 14 days from the letter date

P800 Timeline: From Tax Year End to Money in Your Account

APRIL – MAY 2026

HMRC starts the clock

Tax year ends 5 April. Your employer sends P60 by 31 May. HMRC begins automatic reconciliation — no action needed from you yet. Most people won't hear anything in these months. If you haven't received your P60, ask your employer before contacting HMRC.

JUNE – OCTOBER 2026

Letters start arriving

This is when most P800 letters are sent. HMRC calculates everyone's Income Tax between June and November. If you have a Personal Tax Account, you may see a digital notification before the paper letter arrives. Simple cases (single job, no benefits) tend to be reviewed first.

NOVEMBER 2026 – MARCH 2027

Later letters and complex cases

If you had multiple jobs, changed employers, received benefits, or had pension income, your case may take longer. This doesn't mean something is wrong — it means HMRC needs more time to reconcile your records. Check your Personal Tax Account online if you want to see whether a calculation has been issued.

AFTER MARCH 2027

Still nothing? Here's what to do

If you haven't received a P800 by early 2027 but believe you overpaid tax, log into your Personal Tax Account on GOV.UK. You can also write to HMRC with details of your income and tax paid. Keep records of any correspondence dates — this helps if you need to follow up later.

2024/25 vs 2025/26: tax year timelines compared

P800 timing follows the same pattern every year, but the dates shift with each tax year. This side-by-side view helps you check whether your expectations match the current year.

GOV.UK says tax calculation letters are sent between June and March of the following tax year. If you are comparing the two years, the pattern is the same — only the dates move forward by one year.

How long you might wait — by situation

Finding out when your P800 will arrive depends on what your tax records look like. The general window is June to March, but these common scenarios may give you a better idea.

One job, no extra income

Simpler cases are usually processed earlier, often between June and August. If your tax affairs are straightforward, you are likely to be near the start of the window.

Changed jobs during the year

HMRC may need more time to match records from different employers. These cases often land between September and November.

Savings interest or dividend income

Banks and providers report to HMRC on their own schedules, which can push a calculation later into the window.

Pension income alongside PAYE

Multiple income streams can take longer to reconcile. Some of these cases arrive between November and the following March.

The table below shows the published HMRC pattern for completed tax years. Because GOV.UK guidance has been consistent, the 2025/26 tax year is expected to follow the same pattern — from June 2026.

2024/25June 2025Aug–Oct 2025Jun 2025 – Mar 2026

HMRC says tax calculation letters for the 2025/26 tax year are expected from June 2026. The information above reflects the pattern GOV.UK has published for completed tax years, and the same timing structure is described in current HMRC guidance for the year ahead.

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 what your P800 letter means.

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 can I expect to receive my P800?

HMRC says P800 tax calculation letters are usually sent between June 2026 and March 2027 for the 2025/26 tax year. Many people receive them earlier in that window, but some cases take longer. If you have already received your letter, you can claim your refund online here.

Where is my P800 letter? I have not received it yet

Before June: too early. June-Oct: most people receive it. After Oct: check your account.

When can I expect my HMRC tax refund?

Online refunds are usually paid within 5 working days. Cheques can take longer — usually around 14 days if sent automatically.

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. If you have not claimed yet, follow our step-by-step claim guide.

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.

What if I have been waiting longer than expected?

Check tax year → confirm claim status → review Personal Tax Account → contact HMRC if needed.

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.
