Why Is My Tax Refund Taking So Long?

How Long Does an HMRC Tax Refund Take?

The time required to process an HMRC tax refund depends on the type of claim and whether HMRC can verify the information without requesting anything further.

Processing times can be affected by:

• The type of tax refund being claimed
• The way the claim was submitted
• Whether HMRC requires additional information
• The number of employments or income sources involved
• The complexity and value of the claim
• Whether the claim is selected for additional checks
• Whether HMRC's records match the information submitted
• HMRC's workload at the time

A straightforward PAYE repayment may be processed more quickly than a claim involving several employers, substantial work expenses, Self Assessment or CIS deductions .

Why Is My Tax Refund Delayed?

A delay does not automatically mean that your refund has been refused. HMRC may simply need more time or information before it can confirm the repayment.

1. HMRC Is Experiencing High Demand

HMRC receives higher volumes of returns, claims and enquiries at certain times of the year.

Busy periods can include the weeks surrounding the Self Assessment filing deadline and the end or beginning of a tax year.

Where HMRC is handling a large number of claims, responses and processing may take longer than usual.

2. HMRC Needs More Information

HMRC may require additional evidence before it can approve a claim.

This could include:

• Evidence of work-related expenses
• Mileage or travel records
• Employment information
• Payslips or P60 details
• CIS payment and deduction statements
• Missing income information
• Identity verification
• Clarification of bank or repayment details

Responding promptly and supplying the information requested can help prevent the claim from remaining unresolved for longer than necessary.

3. Your Claim Has Been Selected for Review

HMRC carries out checks before and after some repayments are issued.

A review does not necessarily mean that HMRC believes the claim is incorrect. It may need to verify the taxpayer's identity, the expenses claimed, the tax already paid or other details connected with the repayment.

If HMRC opens a formal enquiry, it may withhold all or part of a repayment until the relevant checks have been completed.

4. You Have Recently Changed Jobs

Changing jobs can make a PAYE calculation more complicated, particularly if HMRC has not yet received or matched information from your former and current employers.

Delays may occur where:

• Your previous employment is still shown as active
• Your P45 details have not been applied correctly
• You were placed on an emergency or temporary tax code
• Two employers reported overlapping pay periods
• HMRC needs to reconcile tax deducted by different employers

5. You Are Claiming Work-Related Expenses

Claims involving mileage, travel, professional fees, tools, uniforms or other employment expenses may require HMRC to review additional information.

Claims are more likely to proceed smoothly when the expenses are correctly categorised and supported by suitable records.

Our guide to allowable work and business expenses explains some of the costs that may qualify.

6. Your Mileage Claim Requires Further Checks

Mileage claims can be delayed where journey records are incomplete, the workplace status is unclear or employer reimbursements have not been recorded correctly.

HMRC may need to establish:

• Whether the journeys were for business purposes
• Whether they involved temporary or permanent workplaces
• How many business miles were travelled
• What mileage rate your employer paid
• Whether any part of the journey was ordinary commuting

7. Your CIS Records Do Not Match

CIS refunds can require HMRC to match deductions shown on the tax return or repayment claim against information reported by contractors.

Delays can arise where:

• A contractor has not reported deductions correctly
• Payment and deduction statements are missing
• The figures claimed do not match HMRC's records
• Multiple contractors are involved
• A required return has not been submitted
• Other tax liabilities remain outstanding

Our CIS Tax Refund service explains how we help construction workers review their deductions, income and allowable expenses.

8. Your Self Assessment Return Requires Review

A Self Assessment repayment may be delayed if HMRC needs to verify the return, the income reported, tax deducted or the expenses claimed.

A return may also show a repayment while another part of the taxpayer's HMRC account contains an amount due.

Where appropriate, HMRC may use some or all of the overpayment against another tax liability rather than paying the entire amount directly.

9. Your Bank or Repayment Details Need Checking

Incorrect or incomplete payment information can prevent HMRC from issuing a repayment.

Check that the following details are accurate:

• The account holder's name
• The bank account number
• The sort code
• The repayment recipient
• Any authority allowing payment to an agent or nominee

HMRC may also complete security checks before releasing a repayment.

10. There Is an Outstanding Tax Liability

A calculated refund does not always result in the full amount being paid into your bank account.

HMRC may use an overpayment against tax that is already due or becoming due, depending on the circumstances and the type of tax involved.

This can result in a smaller payment or no direct payment, even though the original calculation showed that tax had been overpaid.

Has HMRC Lost My Claim?

A long delay does not necessarily mean that HMRC has lost your claim.

The claim may still be:

• Waiting to be processed
• Undergoing security checks
• Waiting for information from an employer or contractor
• Waiting for supporting evidence from you
• Being reviewed by another HMRC team
• Held because another return or liability is outstanding

If a considerable amount of time has passed, check whether HMRC has sent a letter, online message or request for additional information.

You should also confirm that the return or claim was successfully submitted and that HMRC has the correct contact details.

Can I Speed Up My Tax Refund?

You cannot force HMRC to approve a refund immediately, but you can reduce the risk of avoidable delays.

Before submitting a claim:

• Check that your personal information is correct
• Include all relevant income sources
• Use the correct claim route
• Check that tax deduction figures match your records
• Only include legitimate allowable expenses
• Retain documents supporting the claim
• Provide accurate repayment details
• Submit any outstanding returns

After submitting the claim:

• Check your HMRC online account for messages
• Respond promptly when HMRC requests information
• Keep copies of documents sent to HMRC
• Record the date and method of submission
• Avoid submitting duplicate claims unless instructed

What If HMRC Asks for More Information?

A request for additional information does not automatically mean that your refund has been rejected.

HMRC may need supporting documents to check one or more parts of the claim.

You should:

• Read the request carefully
• Check the deadline for responding
• Supply the documents specifically requested
• Keep copies of everything provided
• Explain clearly where a document is unavailable
• Avoid sending unrelated or contradictory information

If you do not understand the request, seek clarification rather than guessing what HMRC needs.

Missing a response deadline can result in further delay and may affect how HMRC treats the claim.

How Can I Check the Progress of My Refund?

The appropriate way to check your refund depends on how the refund arose and how the claim was submitted.

You may be able to review the position through:

• Your HMRC Personal Tax Account
• The HMRC app
• Your Self Assessment online account
• Relevant HMRC correspondence
• The adviser or agent who submitted the claim
• HMRC's relevant telephone or online enquiry service

Before contacting HMRC, have your National Insurance number, Unique Taxpayer Reference where applicable, claim details and relevant correspondence available.

If Go Tax Refunds is handling your claim, we will keep you updated and communicate with HMRC on your behalf where our authority allows us to do so.

Common Reasons People Think Their Refund Is Late

People often decide that their refund is overdue based on another person's experience or a general processing estimate found online.

Common assumptions include:

• A friend received a similar refund more quickly
• An online post suggested that all refunds take the same time
• The claim was submitted during a busy period
• An HMRC request for information was overlooked
• The taxpayer expected payment immediately after submission
• The claim involved more information than expected
• HMRC approved the calculation but has not yet issued payment

Every claim is based on different employment records, income, deductions, expenses and verification requirements.

Two people claiming similar amounts can therefore experience very different processing times.

What Happens Once My Refund Has Been Approved?

Once HMRC has approved and issued a repayment, the time required to receive it depends on the payment method.

A repayment may be made by bank transfer, cheque or another method specified by HMRC.

For some P800 repayments claimed online, HMRC states that the money is normally sent within five working days. That timeframe applies after the calculation has been completed and the online repayment has been claimed; it should not be treated as the processing time for every type of refund claim.

Before assuming a payment is missing, check:

• The date on which HMRC issued the repayment
• The payment method selected
• The bank details entered
• Whether HMRC used the repayment against another liability
• Whether a cheque was sent to the correct address

Can My Tax Refund Be Reduced or Refused?

HMRC may reduce, withhold or refuse a repayment if the information submitted does not support the amount claimed.

This could happen where:

• Income or tax deductions were reported incorrectly
• An expense does not qualify for tax relief
• The same expense was claimed more than once
• The taxpayer was already fully reimbursed
• Supporting evidence is insufficient
• HMRC's records show a different amount
• Another tax liability is outstanding
• The claim falls outside the applicable time limit

HMRC may contact you for clarification before making a final decision. It could approve the full amount, approve a smaller amount, offset the repayment or reject the claim.

This is why it is important to submit complete and accurate information from the beginning.

When Should You Contact HMRC?

It may be appropriate to contact HMRC where:

• The published or advised response time has passed
• Your online account shows no progress for an extended period
• You believe HMRC is waiting for information you already supplied
• Your bank or contact details have changed
• A payment was issued but has not arrived
• You do not understand a letter or information request
• The refund amount appears incorrect

Contacting HMRC very shortly after submitting a claim will not necessarily accelerate it. Check the expected response time that applies to the relevant claim before following up.

If an authorised tax adviser submitted the claim, speak to the adviser before contacting HMRC separately. This can help avoid duplicated or inconsistent communication.

Frequently Asked Questions

Why is my tax refund taking longer than my friend's?

Every tax refund is different. The type of claim, employment history, expenses, HMRC records, security checks and time of submission can all affect processing.

Two people claiming similar amounts will not necessarily receive their refunds at the same time.

Does a delay mean there is a problem?

Not necessarily. Your claim may be waiting to be processed or undergoing routine checks.

However, you should check whether HMRC has requested additional information or whether the expected response time has passed.

Should I contact HMRC about the delay?

Contact HMRC where the relevant expected response time has passed, a payment has not arrived or you need to respond to an information request.

If Go Tax Refunds submitted the claim for you, contact our team first so that we can review the position and approach HMRC where appropriate.

Can inaccurate information delay my refund?

Yes. Incorrect employment details, tax deductions, income figures, expense claims or bank information can cause HMRC to request clarification or amend the claim.

Will HMRC pay interest because my refund was delayed?

Interest treatment depends on the type of tax, the circumstances and the relevant statutory rules. A processing delay does not automatically mean that additional interest will be paid.

Can I submit the claim again?

You should not normally submit a duplicate claim simply because the original is taking longer than expected.

Check that the original was received and establish its status before submitting an amendment or replacement.
