The Pensions Minister is in favour of using self-employed people's tax returns to deduct pension savings in a move intended to help millions save for their retirement, MoneySavingExpert.com can reveal.

In a recent interview with MSE, Pensions Minister Richard Harrington admitted that his favoured approach to solving the automatic-enrolment conundrum facing the UK's army of self-employed workers would be to adapt the annual tax return system so that pension contributions could also be made.

If you work for an employer and earn more than £10,000 a year, the chances are your company has already signed you up to a workplace pensions scheme via auto-enrolment. This means money will be automatically subtracted from your monthly pay cheque and added to your private pension pot, providing you don't opt out.

The auto-enrolment minimum contribution is initially 2%, of which at least 1% must be paid by your employer. Over time this will increase to a total of 8%, of which at least 3% must be paid by your employer.

However, no such auto-enrolment scheme currently exists for the five million self-employed people around the country. If such a scheme were to become policy it could go some way towards boosting pension provision for the self-employed.

It's not yet clear how it would work in practice and many questions remain about how beneficial the scheme would be. While employees who are auto-enrolled get matching employer contributions, that wouldn't to apply to the self-employed - though the tax implications and possible benefits of the scheme are yet to be thrashed out.

As things stand now, if you're self-employed, you have to actively take out a pension to guarantee you're putting money aside for your retirement. According to figures produced by the Department for Work and Pensions (DWP), just one in seven self-employed people are contributing to a pension.

'Self-employed auto-enrolment equivalent could be through tax returns'

The DWP launched a review earlier this month to investigate how auto-enrolment can be developed further to encourage more people to put money aside for their old age.

As part of that review the DWP hopes to develop a better understanding of how self-employed people can be included within the wider auto-enrolment regime.

While it's only at discussion stage, Harrington told MSE he's in favour of linking pension saving for the self-employed to their tax returns.

He said: "What do all self-employed people have in common? Tax returns. So seeing as there's that common bond between them it seems to me not too difficult to say that a self-employed person's equivalent of automatic enrolment could be through their annual tax return.

"There could also be some tool that shows how much tax you save if you put in £1,000, or whatever it is. So we're looking at all that kind of thing in terms of new ways to do it."

He added: "I've included a load of things in [the auto-enrolment] review that we didn't have to do; one of them is looking at groups that aren't part of the automatic-enrolment scheme, which are not just self-employed people but also people who have multiple jobs where there is not one income more than £10,000.

"If you're looking at self-employed people then it's obviously more difficult because they don't have an employer, so our review will be looking at how to include these people in an auto-enrolment system."

From 2019 the minimum auto-enrolment will increase to 8%, of which at least 3% must be paid by your employer

How would auto-enrolment for self-employed people work?

The DWP review is still in its 'call for evidence' stage and so it's not yet fully clear how auto-enrolment via the tax return system would work.

Financial services company Hargreaves Lansdown – which has previously championed using self-employed people's tax returns as a way to deduct pension savings – claims the process would be relatively straightforward.

Tom McPhail, Hargreaves Lansdown's head of retirement policy, said using the tax system for self-employed auto-enrolment would essentially involve building in an additional line on a tax return that addressed pension savings.

So for example, if you're self-employed and you earn £20,000/year you pay 20% tax, which works out at £1,800 once the £11,000 tax-free allowance is factored in. Under the auto-enrolment proposals you would pay an additional 5%, which would go towards your pension.

McPhail said: "The idea is still in its early stages, but there's policy interest. However, it's complicated by the fact that it requires buy-in from Treasury, the DWP and [HM Revenue & Customs]."

What other options are being discussed?

Another option for self-employed auto-enrolment mentioned by former Pensions Minister Sir Steve Webb involves exploiting the national insurance (NI) system.

When the self-employed fill in their annual tax return they are assessed for income tax and for class 4 NI, which is a profits tax. Sir Steve's proposal would involve the Government raising class 4 NI contributions – which apply to self-employed people earning more than £8,060/year – from 9% to 12%.

He explained: "Last year I produced a Royal London policy paper, 'Britain's Forgotten Army', about pensions and the self-employed, suggesting that by default their class 4 rate should be raised from 9% to 12% but they could nominate a pension scheme to receive the extra 3% if they wished.

"This would be in effect an 'employer' contribution into a pension scheme. They would then have to put their own 5% gross (as with employed earners once automatic-enrolment is up and running in full) and they would end up with 8% in total.

"They wouldn't have to put their own contribution in, but if they didn't then they would lose the 3% (it would go to the Treasury). This is analogous to the way that an employed earner who opts out of automatic enrolment loses their employer contribution."
