SIPP vs Workplace Pension: What's Right for You?

The short answer: Yes, you can have a SIPP and a workplace pension at the same time. Your workplace pension is where your employer pays in. A SIPP (self-invested personal pension) gives you more say over investments. Both get tax relief, and in 2026/27 everything paid into all your pensions shares one £60,000 annual allowance.

Can I have a SIPP and a workplace pension at the same time?

Yes. MoneyHelper confirms you can have both a workplace pension and a SIPP, or any number of pension types. GOV.UK even lists "keep paying into both" as an option if you already pay into a personal pension when you join a workplace scheme.

They do different jobs, so they sit side by side quite happily. Your employer sets up your workplace pension and usually pays in too. A SIPP is a pension you set up yourself: you choose the provider and, if you want to, the investments.

MoneyHelper's view is that if you have an employer, paying into their scheme is usually better than a SIPP, unless you want a separate pension alongside it. That's because you usually get your employer's money and charges are often lower. A SIPP tends to come in on top, not instead.

Opting out of your workplace pension usually means missing out on employer contributions and tax relief. MoneyHelper says it's often like turning down extra pay.

Capital at risk. The value of your pension can go down as well as up, and you may get back less than you pay in.

Tax treatment depends on the individual circumstances of each client and may be subject to change in future.

What's the difference between a SIPP and a workplace pension?

The big differences are who pays in, how tax relief arrives and how much say you get over investments.

This assumes a defined contribution workplace pension (the most common type) and a standard SIPP. Sources: GOV.UK minimum contributions, GOV.UK relief at source, MoneyHelper on SIPPs and MoneyHelper on transfers.

On the workplace side, your employer must enrol you automatically if you're aged 22 to State Pension age, earn at least £10,000 a year and usually work in the UK. The legal minimum is 3% from your employer and 5% from you, usually on earnings between £6,240 and £50,270 a year. MoneyHelper explains that your 5% is typically 4% from you and 1% in tax relief.

On the SIPP side, GOV.UK says a SIPP lets you control the specific investments in your pension. You don't have to pick them yourself, though. Most SIPP providers will manage your money for you unless you choose otherwise. For a wider look at the options, see our guide to the different types of pension.

Can my employer pay into my SIPP instead of the workplace scheme?

Sometimes, but your employer doesn't have to. If they agree, and your SIPP provider accepts payments from them, they can pay in. In practice, many employers will not pay their contribution into a different scheme, according to MoneyHelper.

The law asks your employer to put you in a pension scheme and pay into it, and how much you both pay depends on the scheme your employer has chosen. That's why the usual route is their scheme, not yours.

If you'd like to ask, here's what to check:

1. Will your employer do it? Ask HR or payroll whether they'll pay into a personal pension you choose.

2. Will your SIPP accept it? MoneyHelper says you need to ask the employer or pension provider whether they allow other people to pay in.

3. What happens to your workplace pension? If you opt out to make the switch, you may lose your employer's money unless they agree to pay it elsewhere.

4. Is the SIPP registered with HMRC? A scheme must be registered with HMRC to get tax relief.

If your employer does pay in, the money is treated well for tax. GOV.UK says no tax is charged on the contributions an employer pays to a registered pension scheme for an employee. And all employer pension contributions stay free of National Insurance. Your employer gets its relief by deducting the cost as a business expense. No extra 20% is added on top of employer money, because only payments other than from your employer count as yours for tax relief.

Do I get tax relief on a SIPP as well as my workplace pension?

Yes. You can get tax relief on both, as long as the total you pay in yourself is no more than 100% of your annual earnings and everything stays within your annual allowance. What differs is how the relief reaches you.

There are two ways it happens:

• Net pay. Your employer takes your contribution before Income Tax. GOV.UK says this gives you full tax relief at the basic, higher or additional rate. But if you don't earn enough to pay tax, you won't get relief this way.

• Relief at source. You pay from taxed money and the provider adds 20%. This is used in all personal pensions, including SIPPs, and some workplace pensions.

If you pay 40% or 45% tax and your pension uses relief at source, you claim the extra yourself. That's an extra 20% on income taxed at 40%, or 25% on income taxed at 45%. You can claim online, contact HMRC or use your Self Assessment return. MoneyHelper says you can claim for the previous 3 tax years too, so it's worth checking if you've missed some. Our simple guide to pension tax relief covers this in more detail.

Not paying Income Tax? In a relief at source pension, you still get 20% added on up to £2,880 a year if you have no earnings.

Example: what £100 into a pension really costs

Here's how much £100 going into your pension costs you, using MoneyHelper's figures. The numbers are illustrations, not a forecast.

This assumes relief at source (as in a SIPP), income taxed at that rate, and that you claim the extra. With net pay, the end cost is the same, because the relief comes off your tax bill straight away.

How much can I pay into both before I hit a limit?

In 2026/27 the standard annual allowance is £60,000. It covers all your private pensions added together. That includes money from you, your employer and anyone else. It's one limit, not one per pension.

Three things can change your limit:

• Carry forward. You may be able to use unused allowance from the previous 3 tax years. This is often what people mean by the "3 year rule".

• High income. Your allowance is tapered if your threshold income is over £200,000 and your adjusted income is over £260,000.

• Taking money out. If you start taking your pot flexibly, your allowance could drop to £10,000.

The 100% of earnings rule only limits what you pay in and get relief on. Your employer can pay in more than you earn, within the allowance. MoneyHelper's example: someone earning £25,000 could pay in £25,000, and their employer could add another £35,000 tax-free.

Example (made-up figures): Priya's workplace pension gets £3,000 this year from her and her employer. She also puts £4,000 into a SIPP, including tax relief. Her total is £7,000, which counts once against her £60,000 allowance.

How does salary sacrifice fit in?

Salary sacrifice is a workplace option. You give up part of your salary and your employer pays it into your pension. It's treated as an employer contribution, so you pay less Income Tax and National Insurance. Your employer saves National Insurance too, and might add some or all of it to your pension.

Example (made-up figures): take £1,000 of pay for a basic-rate employee in 2026/27. The Income Tax rate is 20% and employee National Insurance is 8% on this slice.

• Paid as wages, then into a SIPP: £200 tax and £80 National Insurance leave £720. Pay that into a SIPP and the provider adds 20%, so £900 goes in.

• Salary sacrifice: your employer pays the full £1,000 into your pension, and your take-home pay drops by £720.

That's £100 more in the pension for the same drop in take-home pay, before any extra from your employer.

There are two catches. From April 2029, only the first £2,000 a year of employee contributions through salary sacrifice will be free of National Insurance. And a lower salary can affect other things, like how much you can borrow for a mortgage or your Statutory Maternity Pay.

What should I check before moving an old workplace pension into a SIPP?

You can usually transfer an old workplace pension into a SIPP, but check first so you don't lose something valuable. MoneyHelper suggests looking for:

• exit fees or other penalties for leaving

• guarantees such as guaranteed annuity rates or a with-profits bonus

• a protected minimum pension age that lets you take money earlier

• whether your employer still pays in, as many won't pay into another scheme

GOV.UK adds that you might lose the right to take more than 25% tax-free. If your pension has guaranteed benefits worth more than £30,000, you might have to get financial advice first. A transfer often takes two to six weeks.

Never move a pension because of a cold call, email or text. MoneyHelper warns it's likely a scam. Lost track of an old pot? The Pension Tracing Service can find contact details. Our guides to pension consolidation and transferring to a SIPP go step by step.

What can I do now?

Everyone's situation is different, so we can't say what's right for you. But these checks are quick and free:

1. Look at a recent payslip to see what you and your employer pay into your workplace pension.

2. Ask your employer whether they match extra contributions or offer salary sacrifice.

3. Ask your scheme whether it uses net pay or relief at source.

4. If you pay 40% or more and use relief at source, check you've claimed your extra relief.

5. Add up everything going into all your pensions this tax year and compare it with your allowance.

If you'd like help working through it, MoneyHelper offers free guidance, or you can pay a regulated financial adviser.

Still got questions?

What are the downsides of a SIPP? Fees can add up, as you'll usually pay charges to each provider and a fee each time you change investments. Choosing your own investments takes time. And all investments can fall, so you could get back less than you pay in.

Can I have more than one SIPP? Yes. MoneyHelper says you can have as many pensions as you like, but you'll typically pay charges on each one.

Can my employer pay in more than my salary? Yes, within the annual allowance. The 100% of earnings limit applies to tax relief on your own payments, not your employer's.

When can I take money out? Usually from age 55, rising to 57 from April 2028. That applies to both a SIPP and a workplace pension.

If I opt out of my workplace pension, can I get my money back? If you opt out within a month of being enrolled, you get back what you paid in. You won't get your employer's money, and you'll usually be re-enrolled every 3 years.

How do I check a SIPP provider is safe? GOV.UK says to check the provider is registered with the FCA and that the scheme is registered with HMRC.
