Reading the pension lines on your payslip

Most payslips show more than one pension figure, and it is easy to skim past them. You will usually see your own contribution deducted from pay, your employer's contribution, and sometimes a separate line for tax relief. Labels vary — "pension", "AVC", "salary sacrifice pension" — so check the wording rather than assuming.

Look at both the monthly figure and the year-to-date column. The monthly amount tells you what you are saving now; the year-to-date figure lets you spot a missed month or a change in percentage. If your employer's contribution is blank, zero, or absent entirely, that is worth querying straight away.

Employee contributions: what actually leaves your pay

The percentage on your scheme paperwork does not always apply to your full salary. Auto-enrolment rules work from "qualifying earnings", which for 2025/26 means earnings between £6,240 and £50,270 a year. Many schemes use that band; others use your whole salary. The difference is bigger than most people expect.

On a £30,000 salary, qualifying earnings are about £23,760. A 5% contribution is roughly £1,188 a year, or £99 a month. If your scheme uses full salary, 5% is £1,500 a year — £125 a month. Same headline percentage, noticeably different outcome.

How tax relief reaches you depends on the scheme type:

• Net pay arrangement: your contribution comes out before income tax is calculated, so basic, higher and additional rate relief is applied automatically.
• Relief at source: your contribution comes out after tax, and the pension provider claims basic rate relief and adds it. Pay in £80 and £100 lands in your pot. Higher and additional rate taxpayers need to claim the extra relief through Self Assessment or by asking for a change to their tax code.

Employer contributions: the money you never see

Your employer must contribute at least 3% of qualifying earnings, and total contributions across employer and employee must reach 8%. Many employers offer more than the minimum, often matching what you pay up to a set level.

This is where the practical decision sits. If your employer matches up to 6% and you are paying 3%, you are turning down free money. Check whether the employer contribution is calculated on qualifying earnings or on full salary, and whether it appears in the year-to-date column. Some employers also deduct their contribution from your pay before adding it back, which should still balance out — but it is worth confirming.

Salary sacrifice: smaller headline pay, bigger pot

With salary sacrifice, you agree to reduce your gross salary and your employer pays the difference into your pension. Because your contractual pay is lower, you pay less National Insurance — 8% on earnings between £12,570 and £50,270, and 2% above that. Your employer also saves on employer National Insurance, and some pass part or all of that saving on.

There are trade-offs to weigh up:

• Student loan repayments are calculated on lower earnings, so you repay less now but your pension pot grows.
• Mortgage affordability checks often use the lower salary figure, which can reduce how much you can borrow.
• Statutory maternity, paternity and sick pay are based on average earnings, so a big sacrifice can reduce them.
• You cannot sacrifice below the National Minimum Wage, which caps how much you can give up.

Working out what is really being saved

Add the three parts together: your contribution, your employer's contribution, and any tax relief. On a £35,000 salary with 5% employee and 3% employer contributions on qualifying earnings, qualifying pay is £28,760. That is about £1,438 from you and £863 from your employer — roughly £2,301 a year, or around 6.6% of your salary rather than the 8% the scheme headline suggests.

That number matters when you are deciding whether to increase your contribution. Boosting your own percentage is efficient up to any employer match, and still tax-efficient beyond it. Higher earners should also check the annual allowance — £60,000 for most people, tapering for very high incomes — and whether unused allowance from the previous three years can be carried forward.

Getting into the habit of checking

Once a year, log into your pension provider, confirm your contribution percentages, and check that your employer's payments have arrived. Contributions must generally reach the scheme by the 22nd of the following month, so a gap in the record is a red flag.

Read your annual statement, even briefly. Review your contribution whenever you get a pay rise — a small increase then is far easier than a large one later. And if anything on your payslip does not match your scheme documents, ask your payroll team. It is a reasonable question, and it is your money.
