With the end of the 2025–26 tax year approaching on 5 April 2026, there is still time for taxpayers to increase their pension savings and benefit from valuable tax relief. Pension contributions remain one of the most tax-efficient ways to save for retirement, with relief available at a taxpayer’s highest marginal rate.

Tax relief on private pension contributions is generally available on contributions of up to 100% of relevant earnings, subject to certain limits. The relief effectively reduces the cost of saving into a pension. Basic rate taxpayers benefit from 20% tax relief, while higher rate taxpayers can claim 40% relief and additional rate taxpayers can receive 45% relief on their contributions.

For basic rate taxpayers, the initial 20% relief is usually applied automatically by the pension provider. Higher and additional rate taxpayers can claim the extra relief through their self-assessment or by contacting HMRC if they do not normally file a return.

Most individuals can contribute up to the annual allowance of £60,000 each tax year while still benefiting from tax relief. Contributions above this limit can trigger an annual allowance charge. However, it may be possible to contribute more by using the carry forward rules, which allow unused pension allowances from the previous three tax years to be used, provided they made pension contributions during those years.

When planning pension funding, inflation is often acknowledged but not always fully reflected in contribution decisions. Using an average inflation rate of around 5% over recent years helps to illustrate why this matters so much. Even when inflation appears to be easing in the short term, its long-term effect on retirement income can be significant.

Inflation erodes purchasing power. A pension pot that looks comfortable today may buy far less in real terms by the time retirement arrives. At an average inflation rate of 5%, prices double roughly every fourteen years. This means that someone planning to retire in twenty years’ time will need close to twice the income they might intuitively expect, just to maintain the same standard of living. Ignoring inflation risks building a pension fund that appears adequate on paper but falls short in practice.

Inflation also affects investment returns. Pension growth is often discussed in nominal terms, but what really matters is real growth, that is growth after inflation. A fund growing at 6% per year sounds healthy, but if inflation is averaging 5%, the real increase in value is modest. This has implications for asset allocation, contribution levels and the balance between growth and lower risk investments as retirement approaches.

For those making regular contributions, inflation should influence both the starting level and how contributions increase over time. Flat contributions that are not reviewed regularly lose real value year by year. Linking contribution increases to inflation or at least reviewing them periodically in light of inflation trends, can make a material difference to the eventual outcome.

Finally, inflation uncertainty reinforces the importance of flexibility. Retirement may last twenty or thirty years, during which inflation will vary. Building in a margin of safety, through higher contributions or diversified investments, can help protect against prolonged periods of higher inflation.

Taking inflation seriously is not about pessimism. It is about realism. Factoring an average inflation rate of 5% into pension planning leads to better informed decisions and a greater chance that retirement income will meet expectations when it is most needed.

Automatic enrolment for workplace pensions has helped many employees to start making provision for their retirement with employers and government also contributing to make a larger pension pot.

The law states that employers must automatically enrol workers into a workplace pension if they are aged between 22 and State Pension Age, earns more than minimum earning threshold. The minimum threshold is currently £10,000 and will remain the same in 2026-27. The employee must also work in the UK and not already be a member of a qualifying work pension scheme. Employees can opt-out of joining the pension scheme if they wish.

Under the rules, employers are also required to offer their workers access to a workplace pension when a change in their age or earnings makes them eligible. This must be done within 6 weeks of the day they meet the criteria.

Under the automatic enrolment rules the employer and the government also add money into the pension scheme. There are minimum contributions that must be made by employers and employees.

Both the employer and employee need to contribute. There is a minimum employer contribution of 3% and employee contribution of 4%. This means that contributions in total will be a minimum of 8%: 3% from the employer, 4% from the employee and an additional 1% tax relief. For example, if you pay £40, your employer adds £30, and you receive £10 in tax relief, a total of £80 goes into your pension.

In most automatic enrolment schemes, employees make contributions based on their total earnings between £6,240 (the lower qualifying earnings limit) and £50,270 (the upper qualifying earnings limit) a year before tax. This means that for many employees the 8% contribution rate will not be based on their full salary.

The Additional State Pension is only available to those who reached the state pension age before 6 April 2016 and are receiving the Old State Pension. The Additional State Pension is an extra amount of money paid on top of the basic Old State Pension.

The Old State Pension is designed to provide individuals of state pension age with a basic regular income and is based on National Insurance Contributions (NICs). To get the full basic State Pension, most people need to have had 35 qualifying years of NICs.

Claimants will automatically have received the Additional State Pension if they were eligible for it. Those who had contracted out were not eligible for the Additional State Pension.

If your spouse or civil partner dies, you may be able to inherit some of their Additional State Pension if you reached State Pension age before 6 April 2016. If you do not receive the full basic State Pension, you may be able to increase it by using your spouse or civil partner’s qualifying National Insurance years.

You may also be able to inherit part of their Additional State Pension or Graduated Retirement Benefit. Different rules apply if you reached State Pension age on or after 6 April 2016. If relevant, you should contact the Pension Service to check what you can claim.

The Chancellor has kept the main pension allowances unchanged but has confirmed a new cap on salary sacrifice arrangements that will apply from April 2029.

There had been heated speculation that the Chancellor would change the pension rules to help the government raise taxes, but no changes were announced to the annual allowance (which remains at £60,000) or to the carry-forward rules which can use up previous year’s annual allowances. The lump sum allowance has also remained unchanged at £268,275.

However, the Chancellor announced changes to the salary sacrifice arrangements for pension contributions. Salary sacrifice allows employees to reduce part of their salary or bonus in exchange for pension contributions, which is tax-efficient and helps save for retirement. However, this arrangement has disproportionately benefited higher earners with salary sacrifice costs expected to rise from £2.8 billion in 2016-17 to £8 billion by 2030-31.

From April 2029, the government plans to introduce a cap on salary sacrifice contributions which will limit the amount that can be sacrificed without incurring National Insurance Contributions (NICs) to £2,000 per employee. Salary sacrifice contributions above this amount will be subject to employer and employee NICs. Pension contributions that are not part of a salary sacrifice will remain unchanged.

The Chancellor reaffirmed the government's commitment to maintaining the Triple Lock on the State Pension throughout this parliament. This means that in April 2026, the State Pension will increase by 4.8%. The Triple Lock ensures that the State Pension rises by the highest of three measures: inflation, wage growth, or 2.5%, helping to protect pensioners' income against rising costs of living.

Also, starting from 6 April 2027, the government will close a loophole that allows individuals to use pensions for inheritance tax (IHT) planning. Under the new rules, any unspent pension pots will be brought within the scope of IHT.
