The State Pension and Your SIPP: How They Work Together

I used to assume the State Pension would cover my retirement. When I actually looked into how much it pays, I understood why private pension saving through a SIPP is so important. The State Pension is a foundation, but for most people it is nowhere near enough on its own.

How Much Is the State Pension?

The full new State Pension is £221.20 per week in the 2024/25 tax year, which works out to about £11,502 per year. To get the full amount, you need 35 qualifying years of National Insurance contributions. You can check your own State Pension forecast on the government website.

For context, the average UK household spends around £27,000 to £35,000 per year in retirement for a moderate lifestyle, according to the Pensions and Lifetime Savings Association retirement living standards. So the State Pension covers roughly a third to a half of what most people need. The rest has to come from private savings, which is where your SIPP comes in.

When Can You Claim It?

The current State Pension age is 66. It is rising to 67 between 2026 and 2028, and there are plans to increase it further to 68 at some point in the future, though the exact date is subject to review.

This is important for your SIPP planning because there will be a gap between when you can access your SIPP (currently age 55, rising to 57 in 2028) and when the State Pension starts. If you plan to retire at 57, you need your SIPP to cover all your income needs for roughly 10 years before the State Pension kicks in.

How to Plan Around Both

The smartest approach is to think of your retirement income in two phases:

Phase one runs from when you stop working until State Pension age. During this period, your SIPP needs to provide all your income. You might draw more heavily from your pension during these years.

Phase two starts when the State Pension begins. Your SIPP income can then be reduced because the State Pension provides a baseline. This means your remaining SIPP pot lasts longer.

This phased approach is one reason why our pension drawdown guide recommends flexible withdrawals rather than taking a fixed amount from day one.

Tax Considerations

The State Pension is taxable income, even though no tax is deducted at source. It uses up part of your personal allowance (£12,570). If the State Pension is £11,502, that leaves only about £1,068 of personal allowance for other income before you start paying tax.

This means that almost every pound you withdraw from your SIPP after the State Pension starts will be taxed at at least 20%. Planning your withdrawals around the tax bands is essential for minimising your tax bill.

If you can bridge the gap between SIPP access age and State Pension age using your SIPP, you have several years where you can withdraw pension income using your full personal allowance, paying less tax overall.

Topping Up Your State Pension

If you do not have 35 qualifying years, you can buy additional years through voluntary National Insurance contributions. This costs £824.20 per year (2024/25 rates) and each year adds about £329 per year to your State Pension. That is a very good return, especially if you expect to live for more than a few years after State Pension age.

Check your National Insurance record online and consider filling any gaps. The deadline for buying years before 2016 has been extended, so now is a good time to review.

Do Not Rely on the State Pension Alone

The State Pension was never designed to provide a comfortable retirement on its own. It is a safety net. Building a meaningful SIPP alongside it gives you the flexibility and income you need to enjoy retirement properly.
