A LITTLE CLARITY

Gross pension contribution after provider relief

£10,000.00
Provider basic-rate relief£2,000.00
Illustrative additional relief claim£2,000.00
Net personal cost after illustrated additional relief£6,000.00
Total illustrated tax relief£4,000.00
Personal Allowance restored£0.00

Ordinary earned income only, standard Personal Allowance, established eligible relief-at-source payment within relevant-earnings and remaining gross-relief room. No dividends, savings, Gift Aid, other allowance adjustments, net-pay or salary-sacrifice deductions. Annual allowance, carry forward and MPAA require separate checks. The result is not a tax return or entitlement decision.

Income Tax before and after relief-at-source contribution

Ordinary earned income only. Adjusted net income falls for allowance testing; relief-at-source also extends tax bands. Only the additional relief reduces the Income Tax shown here: the provider adds basic relief directly to the pension.

BEHIND THE NUMBERS

How this calculator works

A relief-at-source provider adds basic-rate relief so an £80 net payment becomes £100 gross. The model compares standard-allowance ordinary-income tax before and after the gross relief, then subtracts provider relief to isolate any further claim. This handles band crossings and Personal Allowance restoration above £100,000. Scottish starter-rate contributors keep the 20% provider relief without repaying a difference. NI and loan deductions do not fall merely because you make a personal relief-at-source payment. Additional relief affects your tax position rather than being added automatically to the pension pot.

Formula and rules

Gross = net / 0.8; provider relief = 20% × gross. Additional relief = max(0, ordinary-tax difference from gross relief − provider relief). Personal cost = net − additional relief.

Assumptions and limitations

Ordinary earned income only, standard Personal Allowance, established eligible relief-at-source payment within relevant-earnings and remaining gross-relief room. No dividends, savings, Gift Aid, other allowance adjustments, net-pay or salary-sacrifice deductions. Annual allowance, carry forward and MPAA require separate checks. The result is not a tax return or entitlement decision.

Worked example

An £8,000 net payment becomes £10,000 gross, including £2,000 provider relief. If the full £10,000 is eligible against income taxed at 40%, an additional £2,000 relief illustration leaves £6,000 net personal cost.

GOOD TO KNOW

Common questions

Is additional relief paid into my pension?

Provider basic-rate relief is added to the pot. Additional relief generally changes your tax position through a claim or tax-code adjustment.

What if my contribution crosses tax bands?

The income-based calculation allocates the tax difference across current regional bands and includes standard Personal Allowance restoration. Supply ordinary earned income, not mixed dividend or savings income.

Do Scottish 19% taxpayers repay 1%?

No. GOV.UK states that qualifying relief-at-source payments still receive 20% provider relief without repaying that difference.
