Avoid These 8 Pension Mistakes Before the Tax Year Ends! (UK Tax Tips) (2026)

With the tax year deadline looming, it's a crucial time for savers to review their pension plans and avoid costly mistakes. Here's an in-depth look at the top eight pension pitfalls and how to steer clear of them before it's too late.

1. Carrying Forward Unused Allowances

Many savers overlook the option to carry forward unused pension allowances, which can significantly boost their contributions. The pension allowance is a generous tax relief benefit, allowing individuals to save up to £60,000 or 100% of their annual earnings (whichever is lower) into their retirement pot. If you haven't utilized your full allowance in the previous three tax years, you can carry it forward, making a substantial contribution this year. However, this is only applicable for the last three tax years, as Chris Eastwood, chief executive of Penfold, reminds us. It's essential to use the Government calculator to determine your unused allowance and make the most of this opportunity.

2. The £100,000 Income Trap

Earning over £100,000 can lead to a costly tax trap if pension planning isn't strategic. Individuals in this income bracket face a situation where they lose 60% of every additional pound earned to income tax, on top of a 40% income tax rate. This combined effect results in a high tax rate. By making a pension contribution before the deadline, you can reduce your adjusted net income, potentially pulling your earnings below the taper and recovering some of the lost tax benefits. This is a crucial strategy for those earning just above £100,000 to optimize their tax situation.

3. Overlooking Non-Earning Household Members

Pension tax relief isn't exclusive to employed individuals. Non-working spouses, partners on low incomes, and even children can receive contributions of up to £2,800 per year, rounded up to £3,600 by HMRC. Chris Eastwood highlights that most families are unaware of this option. Taking the time to review your pension situation and act before the deadline can significantly impact retirement savings. It's a matter of knowing where to look and making the most of these generous allowances.

4. Triggering the MPAA Unintentionally

The Money Purchase Annual Allowance (MPAA) can be a hidden pitfall for pension savers. Taking even a small amount of taxable income from your pension, sometimes just for testing purposes, can trigger this rule. Once activated, the MPAA limits your tax-relieved contributions to £10,000 per year. Mike Ambery, retirement and savings director at Standard Life, warns that people often discover this restriction too late, when they try to make a larger top-up at the end of the tax year. It's crucial to understand the MPAA and its potential impact on your pension contributions.

5. Missing Out on Bonus Sacrifice

Annual bonuses can be a boon, but they may also have unintended tax consequences. A bonus can push your income into a higher tax bracket or trigger extra charges like the High Income Child Benefit Charge (HICBC). Mike Ambery emphasizes the option to redirect bonuses into pensions using salary or bonus sacrifice. While the rules around salary sacrifice are set to change from 2029, it remains an efficient way to contribute to your pension, benefiting from both income tax and national insurance relief. Setting up these arrangements before the bonus is paid is essential.

6. Not Reclaiming Higher-Rate Tax Relief

Higher and additional-rate taxpayers often assume automatic tax relief, but it depends on their pension type. Workplace pensions typically use 'net pay' arrangements, applying full tax relief automatically. However, personal pensions and self-invested personal pensions (SIPPs) use 'relief at source,' where extra relief must be claimed from HMRC. Mike Ambery explains that higher-rate taxpayers can reclaim an extra 20% or 25% of their pension contributions, claimed via self-assessment or directly from HMRC. This is a significant opportunity to maximize pension savings.

7. Ignoring Pensions in Divorce Settlements

Divorce can have significant implications for pensions. Ros Altmann, a former pensions minister, advises those going through divorce to ensure their partner's pension is 'properly valued' and not overlooked. Pensions are often included in divorce settlements, and partners may miss out on a substantial sum if this is not considered. It's crucial to address pension rights and ensure a fair distribution during the divorce process.

8. Paying into a Loved One's Pension

Caring for a loved one presents an opportunity to contribute to their pension. Ros Altmann highlights that a partner can contribute up to £2,880 per year into a pension in your name, even without earnings. HMRC adds tax relief, bringing the total to £3,600. This rule also applies to children and grandchildren. Taking advantage of this option can provide valuable tax relief and contribute to a loved one's retirement savings.

In conclusion, the tax year deadline is a critical time for pension planning. By avoiding these common mistakes and taking proactive steps, savers can optimize their retirement savings, benefit from tax relief, and secure a more financially secure future.
