A Self-Invested Personal Pension (SIPP) is a flexible and tax‑efficient way to save for retirement, giving investors greater control over how their pension is invested. This article explains the types of contributions you can make and the key considerations, such as allowances and tax relief rules, when paying into your SIPP.
Types of Contributions Investors Typically Make
-
Personal Contributions
These are payments you make directly into your SIPP.
- You can contribute up to 100% of your UK relevant earnings, capped at the annual allowance (currently £60,000).
- Even if you have no earnings, you can contribute up to £3,600 gross per year (£2,880 net with £720 tax relief added).
Personal contributions benefit from tax relief:
- 20% basic rate relief is added automatically.
- Higher and additional‑rate taxpayers can claim further relief via self‑assessment.
-
Employer Contributions
Employers can contribute to your SIPP, and these contributions:
- Count toward your annual allowance.
- Are not limited by your earnings, unlike personal contributions.
-
Third‑Party Contributions
A family member or other third party can contribute to your SIPP on your behalf.
- These contributions also receive tax relief (up to the same £3,600 gross if you have no earnings).
-
Regular vs. One‑Off (Lump Sum) Contributions
Investors can choose between:
- Regular monthly contributions, or
- Ad‑hoc lump sums, which may suit those with irregular income (e.g., self‑employed individuals).
Both receive the same tax treatment.
Key Things Investors Need to Be Aware Of
While contributing to a SIPP is generally straightforward, several rules and limits affect how much you can pay in while still receiving tax advantages.
-
Annual Allowance
The annual allowance is £60,000 for the 2025/26 tax year. Contributions above this may trigger a tax charge. Read our article on Contribution limits and the Annual Allowance
-
Carry Forward Rules
If you haven’t used all your annual allowance in the previous three tax years, you may be able to “carry forward” unused amounts, provided you were a member of a pension scheme during those years.
-
Tapered Annual Allowance for High Earners
If your adjusted income exceeds £260,000, your allowance may be reduced.
- The allowance tapers down to a minimum of £10,000 for very high earners.
-
Money Purchase Annual Allowance (MPAA)
If you flexibly access your SIPP (beyond the 25% tax‑free lump sum), the MPAA may apply. Read our article on What is the Money Purchase Annual Allowance
-
Tax Relief Eligibility
Tax relief can only be claimed on contributions up to:
- 100% of your UK taxable earnings, or
- £3,600 for those with low/no earnings.
Pension income or dividends do not count as earnings for contribution purposes.
-
Age Restrictions
You must be under 75 to receive tax relief on SIPP contributions.
Summary
Making contributions to a SIPP offers flexibility, investment choice, and valuable tax advantages. The main types of contributions, i.e., personal, employer, third‑party, and lump‑sum, provide options suitable for different financial situations. However, investors should be aware of rules around allowances, tax relief limits, and how events like flexible withdrawals can reduce future contribution capacity.
