Pension recycling is HMRC's term for using a tax-free pension lump sum to fund extra pension contributions, effectively getting tax relief twice on the same money. Done deliberately and beyond certain thresholds, it breaches anti-avoidance rules and triggers a significant tax charge — so anyone taking a tax-free lump sum while still contributing to a pension needs to understand where the line is.
Why the rules exist
Normally, taking your 25% tax-free pension commencement lump sum and then paying that same cash straight back into a pension would let you claim tax relief on money that was already tax-advantaged once — an obvious loophole. The recycling rules exist to stop people using a tax-free lump sum specifically to significantly and pre-plannedly increase their pension contributions beyond what they'd normally have paid.
The recycling tests
HMRC treats a lump sum as unauthorised recycling only if ALL of the following broadly apply:
- The lump sum, combined with any other lump sums taken in the same 12-month period, is significantly larger than a set percentage threshold (commonly referenced as more than 1% of the standard lifetime allowance figure, though the mechanics changed after the lifetime allowance was abolished — check current HMRC guidance)
- Contributions into the pension increase significantly compared to what would otherwise have been paid
- The increase in contributions was pre-planned, i.e. there was a clear intention linking the lump sum to the extra contributions
- The additional contributions exceed 30% of the lump sum taken
If all these conditions are met, the lump sum can be reclassified as an unauthorised payment, triggering a substantial tax charge on top of losing its tax-free status.
What does NOT count as recycling
The rules are aimed at deliberate, pre-planned abuse — not ordinary pension saving. You are not caught out simply by:
- Continuing your normal, unchanged pension contributions after taking a tax-free lump sum
- Taking a small lump sum below the significance threshold
- Increasing contributions for reasons unconnected to the lump sum — for example, a pay rise, bonus, or a genuinely separate decision to save more
- Coincidentally increasing contributions modestly without a pre-arranged plan to fund them from the lump sum
Worked example
| Scenario | Recycling risk |
|---|---|
| Takes £20,000 tax-free lump sum, continues normal £300/month contributions unchanged | Low — no link, no significant increase |
| Takes £20,000 tax-free lump sum, immediately increases contributions by £8,000 in the same year with no other explanation | High — exceeds 30% of the lump sum, looks pre-planned |
| Takes a small lump sum well below the significance threshold, then increases contributions | Low — threshold test not met |
Common mistakes
The most common trap is taking a large lump sum shortly before or after a planned pay rise or bonus and using it to fund a noticeably higher pension contribution in the same period — even without deliberate tax-avoidance intent, the pattern can look pre-planned to HMRC. People also sometimes assume the rules only apply to huge sums; the significance thresholds can catch moderate lump sums too, especially for people with several smaller pensions taken around the same time.
What to do next
If you're planning to take a tax-free lump sum and are also considering increasing pension contributions around the same time, get advice from a regulated financial adviser or accountant before acting — the recycling rules are fact-specific and the penalty for breaching them is steep.
