As millions turn to self-invested personal pensions for greater control, experts warn that understanding the complex rules is essential to avoid costly mistakes and safeguard retirement savings.
Millions of people are turning to self-invested personal pensions as they look for more control over their retirement savings, but the extra flexibility can also bring traps. AJ Bell has highlighted the questions savers ask most often, and the answers show that a SIPP can be useful only if investors understand the rules on contributions, withdrawals and transfers.
A SIPP is a type of personal pension that lets savers choose from a broader range of investments than many standard pension plans. Moneyhelper says that can include funds, shares and commercial property, while the government adds tax relief to contributions. That greater freedom is part of the appeal, but it also means savers often need to take more responsibility for managing risk and charges.
The annual allowance for most people is £60,000, although total earnings and other contributions can affect how much can be paid in. Those without earnings may still be able to receive tax relief on up to £3,600 a year. AJ Bell also points out that unused allowance can sometimes be carried forward from the previous three tax years, but only if the saver was a member of a pension scheme during those years and does not exceed current earnings.
Access rules matter just as much. Savers can usually begin taking money from a SIPP at the minimum pension age, which is currently 55 and is due to rise to 57 in 2028. Up to 25% of the pot can normally be taken tax-free, and that cash does not have to be withdrawn in one go. The rest can remain invested, often through drawdown, which allows income to be taken in stages.
That flexibility can be valuable, but it also carries risks. Taking too much income too quickly can leave too little for later life, and AJ Bell warns that tax should be part of the planning decision. In some cases, drawing taxable pension income can also trigger the Money Purchase Annual Allowance, cutting the amount that can later be paid into pensions with tax relief to £10,000 a year.
Transfers are another area where caution is essential. Old workplace pensions can often be moved into a SIPP, but AJ Bell warns savers not to rush because defined benefit schemes may contain valuable guarantees that could be lost, and some older defined contribution pensions may offer guaranteed annuity rates. There may also be exit charges. Hargreaves Lansdown says SIPPs are generally available only to UK residents and taxpayers aged between 18 and 75, and that charges, investment knowledge and retirement goals should all be weighed carefully before opening one.
Savers can hold a SIPP alongside a workplace pension, but AJ Bell says it is sensible to check whether an employer offers matching contributions before shifting money elsewhere. Opting out of a workplace scheme to fund a SIPP could mean giving up free employer payments. In practice, the best pension choice is often the one that captures the most available tax relief and employer support before any extra money is moved into a self-managed pot.
