A Guide to Self-Invested Personal Pensions (SIPPs) in the UK

9th August 2025

Self-Invested Personal Pensions (SIPPs) are a UK individual pension scheme where the individual retains authority over where his or her retirement savings are invested. With greater pension law flexibility and rising financial literacy, SIPPs have grown in popularity, particularly with individuals who seek tax effectiveness and freedom of investment.

This manual explains how SIPPs work, how SIPPs tie into the UK tax year, and what to remember when dealing with your pension investments.

What is a SIPP?

A SIPP is a government-approved personal pension scheme under which members can have control over their own investments. Whereas standard personal pensions offer limited fund options, SIPPs allow exposure to a greater range of investments such as:

  • Individual stocks and shares
  • Exchange-traded funds (ETFs)
  • Commercial property
  • Investment trusts
  • Bonds issued by companies and governments
  • Cash and deposit accounts

SIPPs are best suited to those who want more control over their retirement monies and those who feel or have the support to invest independently.

SIPPs and the UK Tax Year

The UK tax year runs from 6 April to 5 April next year. This is important when handling pension contributions, tax relief, and allowance.

Contribution Limits

  • The annual tax year allowance for most individuals is £60,000.
  • If your adjusted income is above £260,000, your allowance can be tapered (lowered) to as little as £10,000.
  • If you’ve taken money from your pension flexibly, you may trigger the Money Purchase Annual Allowance (MPAA), which limits contributions to £10,000.

Carry Forward Rule

You can carry forward unused allowance from the previous three years of assessment if you were in each of the three previous years a member of a UK-registered pension scheme.

Tax advantages of SIPPs

SIPPs enjoy the following tax advantages:

  • Tax relief on contributions: Basic-rate relief (20%) is credited automatically. Higher- and additional-rate taxpayers can claim additional relief in Self Assessment.
  • Tax-free investment growth: Income tax and capital gains tax do not apply on SIPP investments.
  • Tax-free lump sum of 25%: At age 55 (rising to 57 from 2028), you can take out a tax-free lump sum of up to 25% of your pension fund.

Access to Your SIPP

You have access to your SIPP from age 55. There is a variety of options:

  • Take a tax-free lump and keep the rest invested.
  • Drawdown to take flexible income from your pension fund.
  • Buy an annuity, which provides a guaranteed income for life.

The over-25% of tax-free amount you take out is taxed as income at your marginal rate.

 

Investment Choice and Responsibility

More control involves responsibility. Managing a SIPP involves having to:

  • Monitor closely and check your investments periodically.
  • Be aware of market risks and diversification.
  • Ensure you’re not breaking pension regulations, which would mean tax charges.

Many people employ an advisor or choose self-select SIPPs with model portfolios.

 

Charges and Costs

SIPPs can have various fees depending on the provider and type of investments. Standard fees are:

  • Annual account or platform fees
  • Dealing fees to purchase/sell investments
  • Transfer fees
  • Exit fees if transferring your pension

Always shop around and watch how fees can drain your pension over time.

 

Inheritance and Death Benefits

If you pass away before age 75, your SIPP can usually be passed to beneficiaries tax-free. When you are age 75 or older, withdrawals on behalf of beneficiaries are taxed at their marginal rate.

 

People Also Ask (PAA)

Can anyone open a SIPP?
 Yes, as long as you are younger than 75 years old and a UK tax resident, you can set up and contribute to a SIPP.

How much can I contribute to a SIPP each year?
 You can contribute a maximum of £60,000 per year in tax, or 100% of your income—whichever is lower.

Can I pay into both a workplace pension and a SIPP?
 Indeed, you can contribute to them both, and may be able to claim tax relief on contributions to each within your limit.

Is a SIPP better than an ISA for retirement?
 Both have their advantages. SIPPs offer relief on contribution at tax, while ISAs enable tax-free taking out. Most employ both in an attempt to diversify sources of retirement income.

What age should I set up a SIPP?
 You can join it at any age under 75. The sooner you join, the more chance your investments have to grow tax-free.

What happens if I exceed the yearly allowance?
 You’ll be liable to a tax charge on the excess payments and must report it on your Self Assessment tax return.

Are SIPPs secure if my provider goes out of business?
 Yes. SIPP funds are typically ring-fenced from the provider’s assets and will likely be protected by the Financial Services Compensation Scheme (FSCS) to certain levels.

Can I take an existing pension and transfer it into a SIPP?
 Yes, most defined-contribution pensions can be transferred into an SIPP. Ensure that you check for exit charges or loss of benefits before transferring.

What’s the best time to pay into my SIPP?
 Ideally, before the tax year ends on 5 April, make full use of your annual allowance and tax relief opportunities.

Conclusion

A Self-Invested Personal Pension gives you freedom, flexibility, and tax effectiveness for retirement savings. Strategically employed within the boundaries of the UK tax year, SIPPs can be an effective pension pot builder. But they’re not for everyone, so consider your investment decision comfort level and take advice from a financial advisor if you need to.

Whether you’re building wealth over decades or swimming in pensions mid-way through your working life, a SIPP can allow you to take control of your retirement on your terms.
