Pensions and Tax Relief / Lesson 2 of 8

Claiming higher-rate relief

Workshop 6 min read How pension tax relief works Includes a calculator

Four years of it is still claimable. Everything before that is not.

The short answer

  • You claim the gap between your marginal rate and the basic rate already given
  • Always enter the gross contribution, including the provider top-up
  • Claims can be backdated four tax years
  • The relief comes back to you as cash or reduced tax, not into the pension

What you are claiming

The difference between the relief you received and the relief your marginal rate entitles you to.

A year of contributions, higher-rate taxpayer
Contributions from taxed pay            £4,800
Basic rate added by provider            £1,200
                                       --------
Gross contribution                      £6,000

Relief due at 40%                        £2,400
Relief already given at 20%              £1,200
                                       --------
STILL TO CLAIM                          £1,200

An additional-rate taxpayer claims more again, the gap between 45% and 20%.

How to claim

SituationRoute
You file a Self Assessment returnEnter the gross contribution in the reliefs section
You do not file a returnContact HMRC or use your Personal Tax Account
Contributions are regular and ongoingHMRC can build it into your tax code
Earlier years never claimedClaim them, up to four years back

Enter the gross figure

This is the most common error on a tax return. You enter the gross contribution, meaning what you paid plus the basic rate the provider added. Enter only what left your bank and you under-claim by a fifth.

Your annual pension statement shows the gross figure. Use that, not your bank statement.

How the relief arrives

For past years, usually as a repayment. For the current year, often by extending your basic rate band through your tax code, so your take-home rises. Ongoing contributions can be built into the code so the relief keeps coming without an annual claim, which is worth setting up if your contributions are steady.

The bit HMRC does not spell out

Higher-rate relief does not go into your pension. It comes back to you, as cash or reduced tax. People assume claiming it tops up the pot further, and are then confused when a payment arrives instead.

What you do with it is entirely your choice. That is a decision about your own finances, and this course does not make recommendations about it.

Common mistakes

  • Entering the net figure on a return. Use the gross, from your pension statement.
  • Assuming it is automatic. Under relief at source it never is.
  • Letting the four year window close. There is no discretion afterwards.
  • Expecting it to land in the pension. It comes back to you.

Claim back via Self Assessment

As a taxpayer you can reclaim a further through your tax return - it does not go into the pension automatically.

Over the annual allowance

Your gross contribution exceeds the annual allowance for . The excess may attract an annual allowance charge unless you carry forward unused allowance.

Estimate only. Relief depends on your full income and pension scheme type.

Where the money comes from

You Basic-rate relief Reclaimable

For every £1 that lands in your pension, you fund and tax relief covers the rest.

Projected pot to retirement

With relief Your money only

After years at growth, contributing gross a year could be worth about - roughly of that is from tax relief alone.
