how does a SIPP work

self-invested personal pension (SIPP) is similar to a personal pension. However, you will generally have a wider choice of investment options.

If you're wondering how does a SIPP work, it's essentially a pension plan that gives you more control over how you invest your retirement savings..

You can manage this yourself or with the help of an advisor. For more information on how to set up a SIPP, click here.

Summary

  • A SIPP lets you control your pension investments, with access to a wide range of assets like shares and commercial property.
  • You can contribute flexibly and get tax relief; manage it yourself or with an adviser, fees vary by provider.
  • From age 55 (57 from 2028), access funds via annuities, drawdown, or lump sums, 25% is usually tax-free.

How does a SIPP work and how is it different from other pensions?

You can manage your investments or pay a financial adviser to help you. You're in control. So you can make additional investments. Also, make changes to your portfolio as often as you want.

The range of assets includes:

  • Company shares (UK and overseas)
  • Investment trusts
  • Unit trusts
  • Property (not residential) and land
  • Bullion

 

SIPP providers may offer more opportunities than we've listed. Also, each SIPP provider will offer different options.

It may be possible to invest in commercial property. You cannot use a SIPP to invest directly in residential property. However, you may be able to invest indirectly. Such as real estate investment trusts. Not all SIPP providers accept this type of investment. Restrictions on personal use apply.

If not experienced in investment management, you should seek help from an advisor.

How does a SIPP work in practice? Understanding the rules and contributions

How does a SIPP work in terms of contributions? A key feature is that you control how much you save and how often. You can make contributions through regular payments. Also single premium, and your employer can contribute.

You also get tax relief on your contributions. If you're a basic rate taxpayer, you get basic tax relief.

Then higher rate taxpayers get higher relief through their tax return. This could mean you invest at least £500 more into your pension.

This is based on a yearly contribution of £2000. Also, it will depend on your tax bracket.

The government limits how much you can contribute each year and the tax relief you can claim.

Can I change how much I save?

This isn't usually a problem, but you should check with your provider. You can now make many changes online.

Can I pay a lump sum into my SIPP?

Yes, lump sum payments into a SIPP are typically accepted, but will count towards your annual allowance.

Can I have another pension and a SIPP?

Yes, you can have both. Suppose your employer matches any additional contributions you make. It may be worth considering this first.

This is because it is an excellent way to boost your retirement savings.

When considering a SIPP to run outside your workplace pension, you should compare the costs and charges.

It may be cheaper to contribute to your workplace pension.

Is a SIPP a registered pension scheme? 

SIPPs have been registered pension schemes since 2006, offering tax advantages under UK pension rules.

How does a SIPP work: Does paying into a SIPP affect my annual allowance?

SIPP contributions count towards your annual allowance, just like other defined contribution plans.

What are the fees associated with a SIPP?

Fees vary from low cost, where investment options can be limited. Or a full SIPP that offers a broader range of investment options.

These tend to have higher charges. SIPP providers might charge fees such as:

  • Set-up charges
  • Dealing fees for investing. Some fees and costs are fixed. Others are percentage-based, depending on the provider.
  • Annual administration charges.
  • Ongoing charges for the investments.
  • Platform or service charges.
  • Before starting an SIPP, it is worthwhile shopping around to compare fees and costs. These can significantly impact investment returns.

 

What are the income options from a SIPP?

Understanding how a SIPP works at retirement is crucial when planning your income strategy. From the age of 55 (rising to 57 in 2028), you can begin accessing your pension pot. However, the right choice will depend on your age, goals, and personal circumstances.

You could choose to leave the money where it is for now, letting it grow until you’re ready to take it.

How does a SIPP work when taking income?

There are several flexible ways to access your SIPP:

Buy an annuity

This provides a guaranteed income for life or a fixed term. The income is taxable, but you can usually take 25% of the pot tax-free first.

Drawdown

Keep your pot invested and take a flexible retirement income. You can take up to 25% tax-free and the rest as taxable income.

Take lump sums as needed

You can withdraw in stages. The first 25% of each lump sum is tax-free, the rest is taxed.

Withdraw the whole pot

The first 25% is tax-free, and the rest is subject to tax in the year you take it.

Mix your options

You can combine any of the above depending on your needs.

The tax-free amount you can withdraw is capped at £268,275 for most people in the 2024/25 tax year. Because the rules can be complex, it’s wise to speak to a regulated financial adviser if you're unsure.

Do I need a financial advisor to set up a SIPP?

If you’re asking how does a SIPP work without professional advice, the process can still be manageable for those who are confident investors.

No, you do not need a financial advisor to set up a SIPP. Anyone under 75 can start a SIPP, and there are no age limits for transferring other pension pots into one. However, generally, SIPPs are more suitable for those with an understanding of the investment markets. 

Also they have the time to research and actively manage their portfolios. Or can afford to pay a regulated advisor to manage their plan.

Ultimately, a SIPP gives you more control over your retirement savings and how they're invested. At 55, you can access funds through options such as annuities, drawdown, or lump sums.

You can manage your SIPP yourself or with a financial advisor. While financial advice isn't required, it's recommended if you're not comfortable managing investments.
