HMRC Still Sending Cheques: 178,000 Miss £800 Tax Refunds in 2026

HMRC is still sending cheques in 2026 because not every taxpayer has moved to its digital repayment system yet. If HMRC cannot verify your bank details, you do not respond to a P800 letter, or your details are outdated, it may still send a paper cheque.

The problem is that many people never cash those cheques. Around 178,180 UK taxpayers left an estimated £144 million unclaimed last year, with the average missed refund worth about £800.

Key takeaways:

• HMRC issued 1,746,720 refund cheques in the latest year
• Around 10% of those cheques were never cashed
• Most missed refunds happen because people ignore a P800 letter or move house
• HMRC cheques are usually valid for six months
• You can often claim your refund faster through bank transfer using your Personal Tax Account
• HMRC plans to move further towards digital refunds before April 2027

How Many UK Taxpayers Are Missing Out on HMRC Refunds?

A surprisingly high number of people in the UK are missing out on tax refunds they are already entitled to receive. HMRC figures show that 178,180 taxpayers did not cash their refund cheque during the latest reporting year.

As a result, around £144 million remains unclaimed, with the average missed payment worth about £800 per person.

Although HMRC now prefers to repay taxpayers through bank transfer, it still issued 1,746,720 cheques over the year. Around one in ten of those cheques were never cashed.

In many cases, people did not realise they were owed money, ignored the original P800 letter or had moved house before the cheque arrived.

HMRC Refund Statistics	Latest Figure
Total HMRC refund cheques issued	1,746,720
Total uncashed cheques	178,180
Total value left unclaimed	£144 million
Average refund missed per person	Around £800
Percentage of cheques not cashed	Around 10%

These figures show why it is important to check your Personal Tax Account and read any HMRC letters carefully, especially if you changed jobs, moved address or think you may have paid too much tax.

Why Do So Many HMRC Cheques Go Uncashed?

Although HMRC now prefers to send repayments by bank transfer, hundreds of thousands of paper cheques are still being posted each year.

The main issue is not that HMRC is failing to send the money. Instead, the process often breaks down before you receive it or before you cash it.

Many taxpayers do not realise they have overpaid tax. Others are unsure whether a letter is genuine and leave it unopened. In some situations, the cheque arrives but is forgotten in a drawer until it expires.

Tax expert Robert Salter explained the problem clearly when he said:

“It is certainly a bit problematic that HMRC continues to use cheques to settle tax refunds in so many cases.” He added that the current system creates unnecessary delays for people who are already entitled to their refund.

Why Do People Ignore or Miss Their HMRC P800 Letter?

The first sign that you are owed money is usually a P800 letter. HMRC sends this after reviewing your tax record and finding that you paid too much tax during the year.

However, many people ignore the letter because:

• They think it is junk mail
• They worry it could be a scam
• They do not understand what a P800 means
• The letter arrives months after the end of the tax year and is easy to overlook

If you do not respond within the period given, usually around 21 days, HMRC may stop waiting for a digital claim and send a cheque instead. By that point, many people have already forgotten about the original letter.

Shaun Moore, a tax expert at Quilter, said:

“The data highlights how some parts of the tax system are still struggling to keep pace with a digital economy. Overpayments are common, often caused by people changing jobs, being put on the wrong tax code, or having multiple sources of income during the year.”

How Can an Old Address Stop You Receiving Your HMRC Refund?

A large number of missed repayments happen because HMRC is sending letters and cheques to an old address.

This often affects you if you:

• Move house and forget to update HMRC
• Change jobs and your employer still has your previous address
• Use a temporary address while renting or studying
• Have not checked your Personal Tax Account for several years

If HMRC sends a P800 letter or a cheque to your previous address, you may never know that a refund exists. The money does not disappear, but the process becomes slower because you need to contact HMRC and ask for the repayment to be sent again.

A common example is someone who moves home after changing jobs. Months later, they discover that a tax refund cheque was posted to their old address and expired before they could cash it.

Why Are Some HMRC Cheques Never Deposited Before They Expire?

Even when you receive the cheque, there is still a chance it may go unused. Many people no longer visit a bank branch regularly, especially if they manage their finances online.

Some of the most common reasons include:

• You put the cheque aside and forget about it
• You assume there is no deadline to pay it in
• You are unsure how to deposit a cheque using mobile banking
• The amount is smaller than expected and seems less urgent

HMRC refund cheques are usually valid for six months. After that, the bank will not accept them and you must ask HMRC to issue a new one.

An HMRC spokesperson said:

“The vast majority of pay as you earn repayments are issued via bank transfer, which is now the default option, and the quickest and most secure way for customers to receive their money.” They also explained that customers can still choose a cheque, but it is then their responsibility to cash it.

What Is a P800 Letter and Why Does HMRC Send It?

A P800 letter is an official notice from HMRC telling you that you have either paid too much tax or not paid enough during the previous tax year. In most cases linked to HMRC still sending cheques, the letter confirms that you are due a refund.

HMRC usually sends a P800 after the tax year ends in April and after it compares the information from your employer, pension provider and any other income sources.

If the figures do not match correctly, HMRC calculates whether you have overpaid.

The letter normally explains:

• How much money you are owed
• Why you paid too much tax
• How you can claim the repayment
• Whether HMRC wants to pay you by bank transfer or cheque

You may receive a P800 if you:

• Changed jobs during the year
• Were on the wrong tax code
• Had more than one job
• Started receiving a pension
• Stopped working part way through the year

In most cases, HMRC first encourages you to claim your money online through your Personal Tax Account.

If you do not respond, HMRC may later send a paper cheque to the address it has on file. That is one of the main reasons so many repayments are still going unclaimed in 2026.

How Does the HMRC Refund Process Work From Start to Finish?

The HMRC repayment process can seem confusing because it does not happen immediately after you overpay tax. Instead, HMRC reviews your records after the tax year ends and then begins a series of steps to return the money.

Understanding each stage makes it easier to spot a missing refund before it becomes an expired cheque.

What Happens After HMRC Detects You Have Overpaid Tax?

When HMRC sees that you have paid too much tax, it checks your PAYE or Self Assessment records to confirm the amount.

This can happen because:

• Your employer used the wrong tax code
• You changed jobs and paid too much in one role
• You had multiple jobs or pensions at the same time
• You stopped working before the end of the tax year

Once HMRC confirms the overpayment, it creates a repayment record. This does not mean the money arrives immediately. HMRC first sends you a notice explaining the situation and how to claim the refund.

For most PAYE taxpayers, this is done through a P800 letter. Self Assessment taxpayers may instead see the repayment in their online account.

When Does HMRC Send a P800 Letter and How Long Do You Have to Respond?

P800 letters are usually sent from June onwards, after the tax year has ended in April. The letter explains that you are owed money and asks you to claim the refund online. You are generally expected to respond within around 21 days.

During that period, HMRC encourages you to:

• Log in to your Personal Tax Account
• Confirm your identity
• Enter your bank details
• Choose bank transfer as your repayment method

If you complete those steps quickly, the refund can often arrive within a few working days.

Many people miss this stage because the letter arrives long after the tax year ended.

Others ignore it because they are unsure whether it is genuine. That is one of the reasons the system later falls back on sending cheques.

When Does HMRC Automatically Send a Cheque?

HMRC sends a cheque when you do not respond to the P800 letter or when it cannot pay you digitally.

This usually happens if:

• You do not claim the refund online within the response period
• HMRC does not have your bank details
• Your bank details cannot be verified
• You have specifically requested a cheque

Once the cheque is posted, it is sent to the address on your HMRC record. If that address is wrong, the repayment may never reach you.

The cheque then remains valid for six months. If you cash it within that time, the process is complete. If not, you must contact HMRC and ask for a replacement.

The current system therefore works in three stages:

• HMRC detects an overpayment
• A P800 letter invites you to claim online
• A paper cheque is sent only if no digital claim is made

What Are the Main Reasons You May Have Overpaid Tax?

Most people who receive an HMRC refund have not done anything wrong. Overpaying tax is surprisingly common and often happens automatically when your circumstances change during the year.

You may have paid too much tax if you:

• Changed jobs and your new employer used an emergency tax code
• Worked more than one job at the same time
• Received income from a pension as well as employment
• Left work before the end of the tax year
• Were given the wrong PAYE tax code

For example, if you changed jobs halfway through the year, your new employer may have taxed all of your wages as though you had been earning that amount for the full year. That can lead to an overpayment.

The same issue can happen if you start drawing a pension while still working. HMRC may not immediately update your tax code, so you end up paying too much until the records catch up.

Because these situations are common, it is always worth checking your Personal Tax Account if you think you may be owed money.

What Should You Do If Your HMRC Cheque Has Expired?

Finding an old HMRC cheque can be frustrating, especially if you only realise after the six-month deadline has passed.

The good news is that you do not lose the money forever. However, you will need to ask HMRC to issue a new cheque or arrange a bank transfer.

The process can take time, so it is best to act as soon as you notice that the cheque has expired.

How Long Is an HMRC Refund Cheque Valid For?

Most HMRC refund cheques are valid for six months from the date printed on the cheque. After that point, your bank will usually reject it.

Many people assume there is no time limit because the money still belongs to them. Unfortunately, banks cannot process an expired cheque, even if the amount is correct.

If you have an old cheque, check the issue date immediately. If it is older than six months, do not try to pay it into your account because it is unlikely to work.

Instead, contact HMRC and ask for a replacement. The money itself does not disappear, but the original cheque becomes invalid.

How Can You Ask HMRC To Reissue an Expired Cheque?

If your cheque has expired, you need to contact HMRC directly. In most cases, HMRC will cancel the old cheque and send a new one or transfer the money to your bank account.

You can usually start the process by:

• Logging in to your Personal Tax Account
• Using the HMRC app
• Calling the HMRC helpline
• Writing to HMRC if you still have the original cheque

When you contact HMRC, explain that:

• You received a refund cheque
• The cheque is now out of date
• You want the repayment to be reissued

If possible, ask for the replacement to be paid by bank transfer. This is usually quicker and reduces the chance of the same problem happening again.

A typical real-life example is someone who moved house after changing jobs. They later found an unopened HMRC envelope at their previous address several months later. By then, the cheque had expired and they needed HMRC to send the repayment again.

What Information Will HMRC Need Before Sending a New Cheque?

Before HMRC can issue another payment, it normally needs to confirm your identity and make sure the old cheque has not been cashed.

You may be asked for:

• Your National Insurance number
• Your full name and current address
• The cheque number or issue date
• The amount shown on the cheque
• Details from the P800 letter
• Your bank account details if you want a transfer instead

HMRC may also ask you to return the expired cheque by post, especially if it is still in your possession.

To avoid delays, keep all documents connected with the refund, including the envelope and any P800 letter.

The more information you can provide, the easier it will be for HMRC to locate the payment and issue a replacement.

The most important thing to remember is that an expired cheque does not mean you have lost the refund.

It simply means the repayment has moved into a manual process, which can take longer if your records are out of date.

How Can You Claim Your HMRC Refund Faster Through Bank Transfer?

The quickest way to receive your tax refund is usually through bank transfer. HMRC now treats this as the default repayment method because it is faster, safer and less likely to go missing.

If you receive a P800 letter, do not wait for a cheque. Instead, log in to your Personal Tax Account as soon as possible and choose bank transfer.

To speed up the process:

• Sign in to your Personal Tax Account or the HMRC app
• Check that your address and contact details are correct
• Enter your bank account information carefully
• Respond within the 21-day period mentioned in your letter

Once your details are confirmed, HMRC can often send the money within a few working days.

Bank transfer is generally better than a cheque because:

• There is no risk of the payment getting lost in the post
• You do not need to visit a bank branch
• The refund arrives more quickly
• There is no six-month deadline to pay in a cheque

HMRC says that most PAYE repayments are now made this way and that it is the quickest and most secure option available.

How Can You Check Whether an HMRC Refund Letter Is Genuine?

Because HMRC refund scams are common, it is sensible to check whether any letter or message you receive is real before responding.

A genuine HMRC refund letter will usually:

• Be posted to your home address rather than sent by text message
• Mention a P800 tax calculation if you are owed money
• Ask you to log in through your Personal Tax Account
• Avoid asking for bank details by email

You should be cautious if a message:

• Pressures you to act immediately
• Includes a suspicious web address
• Asks for your password or PIN
• Claims you must pay a fee to receive your refund

If you are unsure, do not use any links in the message. Instead, go directly to your Personal Tax Account or contact HMRC yourself.

You can also compare the details in the letter with your recent tax history. If you recently changed jobs, had more than one employer or think you overpaid tax, a genuine P800 letter may make sense. If not, take extra care before sharing any personal information.

What Changes Is HMRC Planning Before 2027?

HMRC is gradually reducing the number of paper cheques it sends and wants most repayments to be made digitally by April 2027. Around one-fifth of taxpayers have not yet moved fully to the newer system, which is why cheques are still being used in some cases.

The planned changes include:

• More repayments sent directly through Personal Tax Accounts
• Greater use of bank transfer as the default option
• Fewer automatic cheques in the post
• Better identity checks to reduce fraud and errors

This does not mean HMRC will stop sending cheques completely. Paper payments are still likely to be available if you do not have online access or if HMRC cannot verify your bank details.

For now, the system remains a mix of digital payments and older paper methods, but HMRC expects the balance to shift much more towards online refunds over the next year.

What Does HMRC Still Sending Cheques Mean for You?

For you, the most important message is simple: do not ignore letters from HMRC. A refund could be waiting, especially if you changed jobs, had more than one source of income or think your tax code was wrong.

Even though HMRC still sends cheques, the faster option is usually to claim online and choose bank transfer. That reduces the risk of delays, lost post and expired payments.

You should also make sure your HMRC records are up to date by checking:

• Your current address
• Your bank details
• Your Personal Tax Account
• Any recent P800 letters

The money does not disappear if you miss a cheque, but the process becomes slower and more complicated. By acting early, you can avoid becoming one of the 178,180 taxpayers who left a refund unclaimed last year.

Conclusion

HMRC still sending cheques in 2026 reflects a tax system that is still moving towards full digital repayments. Although most refunds can now be paid directly into your bank account, paper cheques are still used when HMRC cannot verify your details or when no online claim is made.

The result is that thousands of people continue to miss out on money they are owed. If you receive a P800 letter, respond quickly, update your address and choose bank transfer where possible.

Even if your cheque has already expired, you can still ask HMRC to reissue the payment. Taking a few minutes to check your tax records could make a real difference, especially when the average unclaimed refund is worth around £800.
