The headline numbers
Drawing £40,000 a year from a defined-contribution pension using flexi-access drawdown (taking 25% tax-free in each withdrawal), the take-home is approximately £36,514 a year. There is no National Insurance on pension income, which materially raises the take-home compared to the same income from employment.
| Component | Annual |
|---|---|
| Total drawdown | £40,000 |
| Of which 25% is tax-free | £10,000 |
| Taxable drawdown | £30,000 |
| Personal allowance applied to taxable chunk | £12,570 |
| Income tax | −£3,486 |
| National Insurance (none on pension income) | £0 |
| Take-home | £36,514 |
Effective tax rate: 8.7% of total drawdown. The pension drawdown tax calculator models any combination of drawdown amount and other income.
The bridge years — 65 to 67 — and why they matter
State Pension age is now 67 (rising to 68 from 2044 for those born after 1977). Anyone retiring at 65 has two "bridge years" where DC pension drawdown is the primary income. Those years are strategically valuable because:
- State Pension hasn't started yet, so you have more headroom in the personal allowance and basic-rate band.
- You can draw heavily from DC pension in these years, using the personal allowance fully, without pushing into higher-rate tax.
- Once State Pension starts (full new State Pension £230.25/week × 52 = £11,973/year in 2026/27), it consumes most of the personal allowance — meaning subsequent drawdown is fully in basic rate or above.
The arithmetic for "draw £40k pre-State-Pension vs £40k post-State-Pension":
- Pre (age 65): tax = £3486 (state pension not yet active)
- Post (age 67+ with full State Pension): drawing £40k of taxable + £11,973 State Pension = £51,973 of taxable income, tax = ~£7,881 (about £4,000 more)
For two bridge years, the saving from draining DC harder pre-State-Pension is around £5,000-£8,000 over those years.
Three big decisions that compound for 25 years
- Take the 25% tax-free lump sum on day one, or trickle it across drawdowns? The "trickle" approach (taking 25% tax-free of each individual drawdown via flexi-access drawdown) is more flexible. The "lump" approach (taking up to £268,275 tax-free at the start) frees cash for major early-retirement spending or mortgage clearance, but leaves a smaller tax-free pool for later. The should I take 25% tax-free lump sum decision page walks through the framework, and the tax-free lump sum calculator models specific scenarios.
- The April 2027 IHT change for pensions. Under current legislation, defined-contribution pension pots become part of the estate for IHT from 6 April 2027. This is a meaningful change — pre-2027, a DC pension was one of the most IHT-efficient holdings; post-2027, it becomes one of the least, especially for estates above the nil-rate band combined limit (£500,000 with the full residence nil-rate band). Strategies worth modelling: faster drawdown plus seven-year-rule gifting, spousal bypass trusts, charitable bequests. The IHT guide covers the regime.
- State Pension top-up — yes, almost always. If your State Pension forecast is below the maximum (£11,973 in 2026/27), each missed qualifying year can usually be filled with a £900 voluntary Class 3 contribution, adding ~£330 of guaranteed income for life. Payback is under 3 years. The State Pension top-up decision page walks through eligibility.
The MPAA trigger and why it matters
Taking any taxable income from a DC pension via flexi-access drawdown triggers the Money Purchase Annual Allowance (MPAA), which permanently caps your future pension contributions at £10,000 per year (down from the standard £60,000 annual allowance). For people who plan to phase retirement — drawing some pension while still working part-time — this matters.
The fix: take only the 25% tax-free lump sum (UFPLS at the 25% portion or pure tax-free cash via flexi-access drawdown of just the 25% slice) without taking any taxable income. This does not trigger MPAA. Once you take any taxable income, MPAA is permanent and irreversible.
The most common mistake at this life stage
Two mistakes compete for first place. Mistake 1: drawing too aggressively from the DC pension in early retirement, then running out at 80+. The 4% safe-withdrawal-rate guideline is a starting point, not a guarantee — sequence-of-returns risk in the first 5 retirement years is the single biggest determinant of pot longevity. Mistake 2: not realising that the IHT regime change in April 2027 fundamentally shifts the optimal drawdown rate. Pre-2027, slow drawdown maximised the IHT shelter; post-2027, faster drawdown plus structured gifting may save more in IHT than the lost tax-free growth costs.
Both are situations where a fee-only financial planner — paying £1,500-£3,000 for a one-off retirement plan — typically pays for itself many times over. The site's disclaimer covers the FCA stance: UK Tax Drag is educational, not regulated advice.
