How to Fill Out Form P55 to Claim Back Pension Tax

Form P55 is HMRC’s route to reclaim income tax that was overcharged when you took a flexible payment from your pension. To fill out Form P55, you work through eight pages covering your personal details, every source of income you expect this tax year, any Gift Aid payments, and how you want to be paid, then sign the declaration and send it in. The form only fits one situation: you took a flexible payment, some money remains in the pot, you won’t take further payments before 5 April, and your provider can’t refund the tax itself.¹ If you emptied the pot, took a small lump sum, or live abroad, a different form or a double taxation agreement applies instead.²

What to Have in Front of You Before You Start

The form asks for specific figures, and guessing at them creates problems later. Pull these together first:

Your P45 from the pension provider. This is the single most important document. It shows the taxable amount of the payment and the tax already deducted, both of which you copy straight into the form.
Your National Insurance number, from a payslip, the P45, or any letter from HMRC.
PAYE reference numbers for your pension provider and, if you’re working, your employer. Both appear on P45s and payslips.
Estimated income for the full tax year (6 April to 5 April): employment, self-employment, other pensions, State Pension, taxable benefits, savings interest, dividends, rental income, anything else.¹
Gift Aid totals for the year, and how much of that was one-off payments.
Bank sort code and account number if you want the refund paid directly. Without them, HMRC posts a payable order.

HMRC accepts estimates where you don’t yet have final figures, and says so on the form itself.² The closer your estimate is to reality, the closer the refund is to what you’re actually owed. Round every figure down to the nearest pound.

Working Through the Form Section by Section

The paper P55 runs to eight pages. Most of that length is Yes/No income questions you’ll skip if they don’t apply to you. The same questions appear in HMRC’s online version, which you reach through your Government Gateway account.²

Personal Details, Questions 1 to 9

Questions 1 to 7 cover title, name, address, phone number, best time to call, and date of birth. Question 8 is your National Insurance number. Question 9 asks for your employer’s PAYE reference. Leave it blank if you’re not employed.

Income From All Sources, Questions 10 to 22

This is the section that determines the refund. HMRC totals your income for the year, works out what tax you actually owe, and compares it to what your provider already deducted. The gap is your refund.

Question 10 covers employment. If you have a job, enter the employer’s name, your expected pre-tax pay, and whether you receive taxable benefits such as a company car. Question 11 asks about self-employment profits. Question 14 catches taxable state benefits, including Employment and Support Allowance, Carer’s Allowance, Jobseeker’s Allowance, and the State Pension.

Question 13 is where the pension withdrawal itself goes. Enter the pension company’s name and address, the taxable lump sum, and the tax deducted. Copy these figures directly from your P45. Any mismatch between what you write here and what HMRC already holds from your provider will flag the claim for manual review, so double-check the numbers against the document.

Questions 15 to 19 handle savings interest, both taxed and untaxed. Basic-rate taxpayers get a £1,000 personal savings allowance, higher-rate taxpayers get £500, and additional-rate taxpayers get nothing. If your non-savings income is under £5,000, the £5,000 starting rate for savings at zero percent may also apply. Questions 20 and 21 cover dividends. Question 22 collects anything left over: rental income, trust distributions, commissions, foreign income.

Gift Aid and Payment, Questions 23 to 36

Questions 23 to 25 ask about Gift Aid. Charitable donations through Gift Aid extend your basic-rate band, which can shift some of the pension withdrawal out of a higher band and increase the refund. Enter the total for the year and how much of it was one-off.

Questions 26 to 36 set the payment method. You can have HMRC pay directly into a bank or building society account by giving the sort code, account number, and the name on the account. You can also nominate someone else, such as a tax adviser, to receive the payment on your behalf. Leave the bank details blank and HMRC posts a payable order to your address.

Sign the declaration on page 8. Without the signature the form won’t be processed.

Getting the Tax Math Right

The first 25 percent of a flexible drawdown is normally tax-free, up to a lifetime lump sum allowance of £268,275 across all your pensions.³ The other 75 percent is added to your other income and taxed at your normal rates.

In England, Wales, and Northern Ireland the personal allowance is £12,570, frozen at that level until April 2031.⁴ Above that, income is taxed at 20 percent up to £50,270, 40 percent up to £125,140, and 45 percent beyond.⁵ Scottish residents fall under a different structure, with six bands running from a 19 percent starter rate to a 48 percent top rate above £125,140.⁶ HMRC applies the rates for your country of residence when it works out the refund.

If you’ve transferred part of your personal allowance to a spouse or civil partner under Marriage Allowance, your own allowance drops from £12,570 to £11,310. HMRC uses that reduced figure in the P55 calculation, so more of the withdrawal falls into taxable territory than you might expect.⁷

If You File a Self Assessment Return

Self Assessment filers need to be careful with the income section. HMRC’s own instructions say not to include estimated Self Assessment income in a P55 claim unless you want it factored into the repayment. Balancing payments and payments on account are still due when they’re due, though you can ask HMRC to apply the P55 refund against your next payment on account. Any repayment you receive through P55 has to be reported on your next Self Assessment return.²

Submitting the Claim

Online is faster. Go to the P55 page on GOV.UK and sign in with your Government Gateway credentials, or create an account during the process.¹ The online form asks the same questions as the paper version and lets you track progress afterward.

Postal claims take longer because of transit and manual handling at HMRC’s end.

After You Submit

HMRC aims to process repayment claims within 30 days.¹ That window can stretch during busy periods, particularly around the April tax year end. If you gave bank details, the refund lands in your account. If not, HMRC posts a payable order to your address, which you deposit at your bank.

If HMRC needs clarification or sees a discrepancy between your figures and those reported by your provider, a letter follows. Answering it quickly keeps the claim on track. Unanswered queries push the timeline well past 30 days.

Accuracy and Penalties

Numbers on the P55 matter beyond the size of the refund. Under Schedule 24 of the Finance Act 2007, a document submitted to HMRC that contains an inaccuracy leading to a false repayment claim can trigger a penalty. A careless mistake, where you didn’t take reasonable care, can cost up to 30 percent of the tax at stake. A deliberate inaccuracy rises to 70 percent, and a deliberate inaccuracy with concealment reaches 100 percent.⁸ If you spot an error after submitting, telling HMRC promptly stops the mistake being treated as careless in hindsight.
