Behind on Pension Contributions? A Mid-Year Catch-Up Plan for 2026/27
If you're behind on pension contributions three months into the 2026/27 tax year, here's how carry-forward and increased monthly contributions can get you back on track.
Working Out What "Behind" Actually Means
Being behind on pension saving is relative to your own target, not a single national benchmark — but a useful starting reference point is that many financial planners suggest aiming to contribute (including employer contributions) roughly half your age as a percentage of salary, started early and maintained consistently. If you are three months into the 2026/27 tax year and have not reviewed your contribution level since April, a mid-year check is a low-effort way to catch a shortfall while there is still time to act.
The Carry-Forward Mechanism
If your total pension contributions in a given tax year are below that year's annual allowance, the unused portion can potentially be carried forward and used in a later year — up to three years back. To use carry-forward:
- You must have been a member of a registered pension scheme in the year you're carrying forward from (contributions in that year can be zero).
- The current tax year's allowance must be used in full first, before drawing on carried-forward allowance.
- Carry-forward only extends how much you can contribute with tax relief — it does not create new tax relief beyond what applies to a normal contribution.
| Tax year | Annual allowance | Amount contributed | Unused (available to carry forward) |
|---|---|---|---|
| 2023/24 | £60,000 | £15,000 | £45,000 |
| 2024/25 | £60,000 | £20,000 | £40,000 |
| 2025/26 | £60,000 | £25,000 | £35,000 |
A worked example: someone in this position with £60,000 of 2026/27 allowance plus access to carry-forward could, in principle, contribute a very large sum in 2026/27 (subject to earnings limits for tax relief purposes) — useful for a bonus year or a business owner with a strong year of profits.
Lump Sum vs Increased Monthly Contributions
| Approach | Pros | Cons |
|---|---|---|
| Lump sum catch-up | Gets money invested sooner; simpler one-off decision | Requires available cash immediately |
| Increased monthly contributions | Spreads cost, easier on cash flow | Money enters the market later on average; requires ongoing budget discipline |
Many people use a hybrid: a modest lump sum now, funded from existing savings, alongside a permanently higher monthly contribution rate for the rest of the tax year and beyond.
Checking the Net Effect on Take-Home Pay
Before committing to a mid-year contribution increase, it is worth checking exactly how much your take-home pay will actually fall — the gross contribution amount overstates the real-world impact once Income Tax relief (and National Insurance relief for salary sacrifice arrangements) is accounted for. A £200 gross monthly contribution increase for a basic-rate taxpayer using salary sacrifice, for example, typically costs considerably less than £200 in reduced take-home pay.

Frequently asked questions
How do I check how much unused pension annual allowance I have from previous years?
Your pension provider's annual statement (the Pension Savings Statement, issued automatically if you exceeded the standard allowance, or available on request otherwise) shows your total contributions for each of the previous tax years. Comparing these against each year's applicable annual allowance shows how much unused allowance is available to carry forward. You need to have been a member of a registered pension scheme in each of the three carry-forward years to use its allowance, even if you made no contributions that year.
Can I use carry-forward if I didn't contribute to a pension at all in a previous year?
Yes, provided you were a member of a registered pension scheme (even with a nil contribution) during that tax year. Carry-forward rules require scheme membership, not a minimum contribution level, so a year with zero contributions while still being a scheme member typically still counts as available allowance to carry forward, subject to the usual three-year limit and using the current year's allowance first before earlier years.
Does increasing pension contributions mid-year affect my take-home pay immediately?
Yes. A pension contribution increase — whether through salary sacrifice, net pay arrangement or relief at source — reduces your take-home pay from the next pay period it applies to, offset partly by the tax and (for salary sacrifice) National Insurance relief you receive. The net reduction in take-home pay is smaller than the gross contribution increase, but it is still a real reduction worth checking against your monthly budget before committing to a large mid-year increase.
Is it better to catch up with a lump sum or increase monthly contributions for the rest of the year?
Both are valid, and the right choice depends on cash flow. A lump sum immediately increases your pension pot's time in the market (potentially benefiting from more months of investment growth) but requires having the cash available at once. Increased monthly contributions for the remainder of the tax year spread the cost more evenly and are often easier to sustain within a monthly budget, at the cost of the money entering the pension slightly later on average.
