SIPPs, like other types of pensions, incur management fees, but some also come with platform fees, setup fees, and transaction fees.

Key Takeaways

  • SIPPs offer unmatched flexibility compared to traditional pensions through selecting and managing your own investments, and they come with significant tax advantages: tax relief on contributions, tax-free growth, and tax-efficient inheritance.
  • You can contribute up to 100% of your earnings annually, with a cap of £40,000, benefiting from tax relief.
  • Withdrawals are permitted from age 55, but they might incur tax liabilities depending on how much you take out.

If you're planning for retirement, understanding the reasons to invest in a SIPP can be pivotal in securing your financial future. Projections indicate that the UK SIPP market, currently valued at approximately £500 billion, is expected to grow to £750 billion by 2030.1

This anticipated growth reflects the increasing recognition of SIPPs as a flexible and advantageous pension option.

At EveryInvestor, our team has meticulously researched and fact-checked this guide to ensure you have reliable insights into why a SIPP might be the right choice for your retirement planning.

Let's explore your options and see if a SIPP is the right choice for you...

What's a SIPP & Is It a Smart Investment Choice?

A SIPP (Self-Invested Personal Pension) is a flexible retirement savings plan that allows individuals to manage their own investments, choosing from a wide range of assets; whether a SIPP is a smart investment choice depends on financial goals, risk tolerance, and investment knowledge.

It offers tax benefits and greater control but requires active management and carries investment risks, and for those comfortable making financial decisions, a SIPP can be a valuable tool for long-term growth.

Let's look at SIPPS a little more closely:

Why Should You Invest in a SIPP?

You should invest in a SIPP as it could be a smart choice if you want greater control over your retirement savings while benefiting from tax relief on contributions.

Additionally, SIPPs offer a wide range of investment options, allowing you to build a portfolio that aligns with your risk tolerance and financial goals.

Managing a SIPP, though, requires investment knowledge and regular monitoring, so always seek advice from a SIPP adviser to help you determine whether a SIPP suits your retirement strategy and structure.

Here are all the positive aspects to consider:

What Are the Main Benefits of Investing in a SIPP?

The main benefits of investing in a SIPP include flexibility, tax efficiency, and greater control over your retirement savings, and unlike traditional pensions, SIPPs allow you to invest in a broad range of assets, helping you tailor your investments to your risk appetite.

Contributions benefit from tax relief at your highest income tax rate, effectively increasing your savings potential; additionally, investment growth within a SIPP is largely tax-free, maximising long-term returns.

SIPPs also provide the advantage of consolidating multiple pensions into one manageable account, simplifying retirement planning.

Here’s an overview of the potential benefits:

  • Investment flexibility and control
  • Tax relief on contributions, growth, and withdrawal
  • The option to consolidate pensions
  • Cost-effectiveness
  • Flexible withdrawal options
  • Estate-planning options
  • Accessibility to a large age group
  • An option for the self-employed

What Investment Flexibility & Control Do SIPPs Offer?

A SIPP gives you the flexibility to choose and manage your investments, allowing you to tailor your pension portfolio to suit your risk appetite.

Standard workplace pensions limit investment options, but SIPPs let you invest in stocks, bonds, funds, commercial property, and more, enabling you to adjust your strategy as market conditions change and maximising potential growth.

Here are some aspects of this flexibility and control you may want to explore:

  • Wide range of investment options: You can choose from a diverse array of top assets, such as stocks, bonds, mutual funds, commercial real estate, and more, so you can build a well-rounded and diversified portfolio suited to your risk tolerance and preferences.2
  • Active management and decision-making: An active management and decision-making approach allows you to act responsively to changes in market trends or personal circumstances.
  • Tailoring to individual needs and goals: You can tailor your portfolios in line with your specific needs and goals, such as retirement planning, education funding, or intergenerational wealth preservation.

What Are the Tax Benefits & Relief of a SIPP?

A SIPP offers valuable tax benefits and relief that can enhance your retirement savings; contributions receive tax relief at your marginal income tax rate, meaning basic-rate taxpayers get a 20% boost, while higher and additional-rate taxpayers can claim even more through their tax returns.

Additionally, when you access your SIPP from age 55 (rising to 57 in 2028), you can take up to 25% as a tax-free lump sum, with the remainder taxed as income.

These are benefits and relief factors to be aware of:

Tax Relief on Contributions

The UK government incentivises pension savings by providing tax relief on contributions, meaning that basic rate taxpayers receive a 20% contribution from the government, while higher and additional rate taxpayers can claim back up to 40% and 45% respectively.3

Remember, your annual allowance for tax-free pension contributions is £60,000 or 100% of your annual earnings (whichever is the lower), and you can carry over any unused annual allowance from the previous 3 years.4

Let’s look at 3 practical examples: 

  • John’s a basic rate taxpayer who wants to contribute £1,000 to his pension. When he contributes to his SIPP, he receives 20% tax relief on his payments. That means he only has to contribute £800 to reach a £1,000 contribution, as the government will add the extra 20% (£200).
  • Jane’s a higher rate taxpayer who wants to contribute £1,000 to her pension. She’s entitled to 40% tax relief on her contribution. She can claim back 20% of her contribution via her tax return, and the government adds an additional 20% to her pension pot. This means she only has to contribute £600 in order to reach her £1,000 target.
  • Jack’s an additional rate taxpayer who wants to contribute £1,000 to his pension. He’s eligible for 45% tax relief on his contribution. Jack can claim back 20% via his tax return, and the government adds the remaining 25% to his pension pot. This means he’ll only actually contribute £550 to reach his £1,000 target.

Tax-Efficient Growth

A SIPP provides a tax-efficient environment where investments can grow without being subject to income tax or Capital Gains Tax (CGT).5

This means that dividends, interest, and capital gains earned within the SIPP are reinvested without tax deductions, allowing for greater compounding over time.

By eliminating these tax burdens, SIPPs help maximise long-term investment growth, making them an attractive option for those looking to build a substantial retirement fund.

Tax-Free Lump Sum at Retirement

When you access your SIPP at retirement, you can take up to 25% of your total pension pot as a tax-free lump sum, subject to a cap of £268,275.6

This Pension Commencement Lump Sum (PCLS) provides a valuable opportunity to access funds without incurring immediate tax liabilities.

However, the remaining 75% of your pension is taxable and must begin to be accessed within 6 months of taking the lump sum.7

How Cost-Effective Is a SIPP for Retirement Savings?

A SIPP can be a cost-effective way to save for retirement, but fees and charges vary between providers.

While some SIPPs have low-cost structures, others may charge for setup, administration, trading, and withdrawals, so comparing providers, choosing low-fee investment options, and consolidating pensions where appropriate can help reduce expenses.

Consider these costs and fees:

Competitive Charges & Fees

SIPPs often have competitive and transparent fee structures, and compared to maintaining multiple pensions, consolidating into a SIPP can reduce overall fees and simplify investment management.

Common charges include setup fees, annual administration fees, and trading costs, which vary between providers.

By carefully selecting a provider with low fees and aligning investments with your long-term strategy, you can maximise your retirement savings while keeping costs in check.

Economies of Scale

SIPPs have the potential to offer the advantage of economies of scale, as consolidated pension funds can lead to reduced costs, making them a cost-efficient option for managing and growing retirement savings.11

For example:

  • Hargreaves Lansdown has a tiered fee structure which starts with a platform fee of 0,45% for holding funds of up to £250,000, working down to 0,1% for funds over £1 million (and 0% on the portion of funds over the £2 million mark).12 
  • AJ Bell charges 0,25% for holding funds up to £250,000 and 0% for funds worth more than £500,000.13

Please note that the fees quoted here were accurate on 07/08/2023 and don’t include dealing and transfer charges or other levies. 

Comparing Costs With Other Pension Options

By comparing the costs associated with SIPPs to those of other pension alternatives, you can make well-informed choices, taking into account charges, fees, and investment performance to ensure your pension plan aligns with your financial objectives.

How Do You Consolidate Pensions?

Consolidating pensions under a single umbrella such as a SIPP means you can keep track and adjust your pension funds as needed, as well as taking advantage of potentially lower charges. 

Why it’s essential to keep track of your pension funds

In 2022, the value of lost pension assets stood at £26,6 billion, a figure primarily attributed to pandemic-related job losses and auto-enrolment, where people left jobs with pension schemes that they may not have been aware of.8

This statistic illustrates why it’s critical to be on top of your finances, especially when it comes to your pension—consolidating your pensions could help you do this.

Here are some of the potential benefits of combining your existing pensions:

What Are The Flexible Withdrawal Options?

The flexible withdrawal options associated with SIPPs include the freedom to choose how and when you withdraw money from your pension, offering various options like taking a tax-free lump sum, purchasing an annuity, or opting for flexible drawdown.

Here’s a quick look at the options:

  • Tax-free lump sum: At 55 (rising to 57 by 2028), SIPP holders can withdraw up to 25% of their pension pot tax-free, providing an immediate cash boost.
  • Flexible income drawdown: This allows retirees to leave their pension invested and withdraw funds as needed.14 Funds can still grow tax free, but there is a risk of running out of money if too much is withdrawn quickly.
  • Annuity purchase: Annuities offer a guaranteed income for life or a set period.15 The income amount is fixed once purchased, providing financial certainty for retirees.

These options reflect the versatility of SIPPs, as they cater to different retirement needs and circumstances.

Remember, flexible withdrawals can be accessed from age 55 (57 from 2028) onwards, even if you haven't retired.16 

What are the Estate Planning Advantages?

SIPPs have several estate planning advantages, namely inheritance tax benefits, passing on wealth to beneficiaries, and allowing for nominated successor members for your plan.

Here’s a closer look at these benefits:

  • If you die before 75, your entire SIPP can be inherited tax free.17 
  • Even if you die after 75, your beneficiaries will only pay income tax on withdrawals at their marginal rate.18 This allows beneficiaries to manage inherited funds aligned with their needs and objectives, potentially reducing the inheritance tax burden.
  • Nominating successor scheme members ensures a continuation of SIPP benefits to chosen individuals.19 

How Are SIPPs Designed for All Ages?

SIPPs are designed for all ages, which means younger investors can benefit from SIPPs' long-term growth potential and investment flexibility, allowing them to build a substantial pension pot over time. 

On the other hand, older investors approaching retirement can take advantage of SIPPs' diverse withdrawal options and tax efficiencies, making these products suitable for managing and accessing retirement income. 

Additionally, SIPPs offer a valuable consolidation tool for individuals of any age, enabling them to bring multiple pensions together into a single, easily manageable account.

What are the Advantages for the Self-Employed & Independent Contractors?

SIPPs provide a host of advantages tailored to the unique financial circumstances of self-employed people and independent contractors.

The potential benefits include:

  • SIPPs offer an ideal pension solution for the self-employed and independent contractors because contributions don’t necessarily have to be regular. This means you can tailor your SIPP, perhaps by making irregular lump sum contributions according to the fluctuations in your income.20
  • The flexibility and tax benefits of a SIPP allow self-employed people and independent contractors to take advantage of the tax relief on contributions and investments that grow tax free, potentially leading to a more substantial retirement fund.

Are There Any Reasons Not to Invest in a SIPP?

Yes, there may be reasons not to invest in a SIPP.

While SIPPs offer numerous benefits, they may not be the best choice for everyone

Understanding the potential downsides and risks associated with SIPPs is crucial in making an informed decision about retirement savings.

These potential risks and downsides include:

  • Complexity: SIPPs often require a good understanding of investments, and not everyone has the expertise or time.
  • Higher fees: Compared to standard pensions, some types of SIPPs (like Full SIPPs) may have higher management and transaction fees.21
  • Investment risk: There is a potential to lose money, especially if your investments underperform.
  • Over-reliance: Putting all your retirement savings into a SIPP can lead to a lack of diversification.
  • Limited protections: Unlike some pensions, SIPPs may not offer guarantees on returns or capital.22
  • Responsibility: The onus is on you to make decisions and manage the portfolio.
  • Potentially high charges: Fees for certain investment choices, early withdrawals, or transfers can add up.
  • Tax implications: Without proper planning, there could be unintended tax consequences.23
  • Lack of guaranteed income: Unlike defined benefit pensions, there is no set income in retirement.
  • Regulation and provider risks: Not all SIPP providers or investments within them are regulated, leading to potential losses.

Before diving into a SIPP, it's essential to weigh these considerations against the potential benefits, ideally with the guidance of a financial adviser.

Should I Choose an Alternative to SIPPs?

Whether you should choose an alternative to SIPPs will depend on your goals and personal circumstances, so you should spend some time comparing SIPPs to other pension options to determine the most suitable choice.

Here are some alternatives to consider:

  • Workplace pensions: Automatically set up by employers, these pensions often come with employer contributions, boosting your retirement savings.24 However, they may have limited investment choices compared to SIPPs, and individuals may have less control over their investments.
  • Personal pensions: A straightforward pension plan, often with a limited range of investment options, ideal for those seeking simplicity.25
  • Group Personal Pensions (GPP): Offered by employers but managed by external pension providers, these allow for both employee and employer contributions.
  • Additional Voluntary Contributions (AVCs): Extra savings you can add to your workplace pension to enhance your retirement pot.
  • NHS Pension: A specific defined benefit scheme for NHS employees, offering guaranteed income in retirement based on salary and years of service.
  • Stakeholder Pensions: Similar to personal pensions, but with capped charges and flexible contribution options.

Each alternative has its own benefits and considerations, and it's vital to weigh them against your individual needs and long-term retirement goals.
