How pension PAYE works
UK pension providers operate PAYE in exactly the same way as employers:
- HMRC issues a tax code to the pension provider for each beneficiary
- The provider applies the code to each pension payment
- Income Tax is deducted before the net amount is paid to you
- The provider submits RTI returns to HMRC monthly
The mechanics — codes, thresholds, bands — are identical to employment PAYE.
Common pension tax codes
| Code | Situation |
|---|---|
| 1257L | Pension is your main UK income source (most common in retirement) |
| BR | Secondary pension, basic rate flat 20% (you have another main income) |
| D0 | Secondary pension, higher rate flat 40% (combined income exceeds £50,270) |
| D1 | Secondary pension, additional rate flat 45% (combined exceeds £125,140) |
| 0T | No allowance applied, standard bands from £0 |
| K-prefix | Negative allowance (often used to collect tax owed on State Pension) |
| NT | No tax at source (typically non-UK residence with treaty exemption) |
| W1/M1/X | Emergency basis (common on lump sums) |
Worked example — pension as main income at 65
You're 65, receiving: - State Pension: £11,000/year (paid gross by DWP) - Workplace pension: £18,000/year (paid by pension provider)
HMRC adjusts the workplace pension's tax code to collect tax on State Pension too.
Total income: £29,000 Standard tax: £29,000 − £12,570 = £16,430 × 20% = £3,286
The workplace pension's code is adjusted: instead of 1257L (£12,570 allowance), HMRC reduces it by the State Pension amount: £12,570 − £11,000 = £1,570 → code 157L.
Then the workplace pension's £18,000 with 157L: - Allowance £1,570 - Taxable £16,430 × 20% = £3,286 — matches total expected tax
State Pension is fully covered by the reduced allowance; you pay all your tax through the workplace pension's PAYE.
Worked example — small workplace pension as secondary income
You're 67, still working part-time: - Employment: £25,000/year (main) - Small workplace pension: £4,000/year (secondary)
Your main code: 1257L (uses all £12,570 allowance on the £25,000 job) Your pension code: BR (basic rate, all £4,000 taxed at 20% = £800)
Combined tax: £25,000 main job tax + £800 pension = correct combined tax on £29,000.
Pension lump sums and emergency tax
When you take a pension lump sum (e.g. the 25% tax-free portion, or a fully encashed small pot), the provider often applies Month 1 emergency basis if they don't have your current tax code on file.
Example: £20,000 lump sum, of which £5,000 is 25% tax-free and £15,000 is taxable.
Emergency Month 1 calculation on £15,000: - Monthly allowance: £1,047.50 - Above allowance: £13,952.50 - Basic rate (first £3,141.67): £628 - Higher rate (next £4,189.17): £1,676 - Higher rate continues (£6,621.66 × 40%): £2,649
Total tax withheld: ~£4,953
If your actual annual position would have this lump sum taxed at basic rate (or less), the over-deduction is reclaimed via form P53. Refund usually within 5 weeks of submission.
State Pension — paid gross, taxed via code adjustment
State Pension is paid by the DWP without any tax deducted at source. But it's still taxable income.
HMRC's standard approach: reduce your other pension/employment income's tax code by the State Pension amount.
State Pension amount for 2026/27: typically around £11,500/year for new state pensioners (subject to inflation indexation).
For a pensioner with State Pension £11,500 + other income £20,000: - Main pension/employment code: 1257L reduced by £11,500 → 157L (or 107L) - This collects tax on the State Pension via the other source
If you have no other PAYE income, HMRC sends an annual P800 with your State Pension's tax position, payable via the Self Assessment route if you owe.
Multiple pensions
If you have several pensions (workplace + SIPP + State Pension):
- State Pension: paid gross, taxed via code adjustment elsewhere
- Main pension: 1257L (or reduced 1257L to collect State Pension tax)
- Additional pensions: BR, D0, or D1 depending on combined income
HMRC allocates the allowance to the highest-income source for tax efficiency.
NT for non-UK residents
If you become a non-UK resident and your country has a double-taxation treaty with the UK exempting your pension income, you can apply for NT code on your pension. The provider deducts no UK Income Tax.
The pension may still be taxed in your country of residence under their domestic rules.
Application process: claim form DT-Individual via your country's tax authority (or directly with HMRC if applicable).
Common pension code issues
Issue 1: Lump sum overtaxed - Cause: pension provider applied emergency basis - Fix: P53 form to claim refund
Issue 2: State Pension tax not being collected - Cause: HMRC hasn't reduced your other code yet - Result: you'll owe via P800 reconciliation at year end - Fix: Personal Tax Account or call HMRC to update
Issue 3: Wrong allowance on retirement pensions - Cause: HMRC's records have stale information - Fix: update via Personal Tax Account
Drawdown vs annuity
Both produce taxable income; both use PAYE.
- Drawdown (flexible withdrawals from DC pot): each withdrawal taxed under PAYE for that month
- Annuity (regular fixed income): treated like a regular monthly payment, taxed cumulatively
Annuity is more PAYE-stable; drawdown is more PAYE-volatile because withdrawals can be lumpy.
Self Assessment for pensioners
You may need Self Assessment if: - Total annual income exceeds £150,000 - You have foreign income or pensions - You receive State Pension and other income that isn't fully captured by PAYE adjustments - HMRC asks you to file
For most basic pensioners, PAYE handles tax automatically and Self Assessment isn't needed.
Practical checklist
- Verify your pension's code matches expectations
- Confirm State Pension is being collected somewhere
- For lump sums: expect emergency tax; reclaim via P53
- For non-UK residence: apply for NT via treaty relief
- Multiple pensions: ensure allowance goes to highest-income source
- Use Personal Tax Account to keep HMRC's records current
In short
Pension providers operate PAYE with standard UK tax codes. Main pension gets 1257L (possibly reduced to collect State Pension tax); secondary pensions get BR/D0/D1. Lump sums often hit emergency tax — refund via P53. State Pension paid gross; taxed via code adjustment elsewhere. For broader context see tax codes hub → and redundancy and pension →.
