In the world of UK retirement planning, the Annual Allowance is usually the speed limit. For the 2026/27 tax year, most people can only contribute up to £60,000 across all their pensions before HMRC steps in.
But what if you’ve just received a life-changing bonus? Or perhaps you’ve sold a business or downsized your home and want to “catch up” on years of low contributions?
Enter Carry Forward—the closest thing the UK tax system has to a “get out of jail free” card for pension savers.
1. How Carry Forward Works
Carry Forward allows you to make use of any unused annual allowance from the previous three tax years and add it to your current year’s limit.
For the 2026/27 tax year, you can reach back and “mop up” space from:
- 2025/26: (£60,000 allowance)
- 2024/25: (£60,000 allowance)
- 2023/24: (£60,000 allowance)
If you haven’t contributed to a pension in any of those years, you could theoretically contribute up to £240,000 in a single tax year (£60k x 4 years).
2. The Three “Golden Rules” of Carry Forward
Before you write a check to your SIPP provider, you must satisfy these three conditions:
Rule A: The “Member” Rule
You can only carry forward unused allowance from a tax year in which you were a member of a registered UK pension scheme.
- Crucial: You don’t need to have paid into it. You just need to have had an open account (even a forgotten workplace pension from a previous job counts). If you weren’t a member of any scheme in 2023, you cannot use that year’s allowance.
Rule B: The “100% Earnings” Cap
This is where most people get caught out. While you can carry forward allowance, you cannot carry forward earnings.
- To get tax relief on personal contributions, your total contribution in the current year cannot exceed 100% of your relevant UK earnings for this year.
- Example: If you have £150,000 in Carry Forward space but you only earn £80,000 this year, your personal tax-relieved contribution is capped at £80,000.
- The Loophole: Employer contributions (company payments) are not limited by your earnings. If you own your own Limited Company, the business can often make these large contributions as a business expense, regardless of your salary.
Rule C: The “Use It or Lose It” Deadline
Carry Forward works on a rolling 3-year basis.
- On 5 April 2027, any unused allowance from the 2023/24 tax year will expire forever. If you are planning a large contribution, you must use that oldest “bucket” before the deadline.
3. The “Order of Operations”
HMRC is very specific about which “bucket” of money you use first. You don’t get to choose.
- First: You must fully exhaust your current year’s £60,000 allowance.
- Second: You use the oldest available carry forward year (e.g., 2023/24).
- Third: You move to the next oldest (2024/25), and so on.
4. Case Study: The “Late Starter”
Meet Sarah (Age 52). She earns £120,000. For the last three years, she only put £10,000 per year into her pension while she focused on her mortgage.
- Current Year (2026/27): She wants to make a big move.
- Unused 2023/24: £50,000 available.
- Unused 2024/25: £50,000 available.
- Unused 2025/26: £50,000 available.
- Total Capacity: £60,000 (Current) + £150,000 (Carry Forward) = £210,000.
The Verdict: Because Sarah earns £120,000, she can personally contribute £120,000 this year and get full tax relief, using up her current allowance and £60,000 of her Carry Forward space. If her employer makes the contribution for her, they could potentially put in the full £210,000.

Summary Action Plan
- Audit your statements: Gather your pension savings statements for the last 3 years.
- Calculate the “Gaps”: Subtract what you (and your employer) paid in from the allowance for that year. (Note: The allowance was £40,000 in 2022/23 and increased to £60,000 from 2023/24).
- Check your earnings: Ensure your salary for this year covers the amount you want to pay in personally.
Money Simplified Tip:
“Carry Forward is like a financial time machine. It lets you go back and fix the mistakes ‘Past You’ made by not saving enough. Just remember: even a time machine has a ‘Fuel Limit’- don’t exceed your annual earnings, or the taxman will be waiting when you land.”
