Having more than one job

Updated on 12 April 2021

There are tax, National Insurance and benefit issues to be aware of when taking on an extra job. We aim to help you understand the impact that having more than one job can have on your finances.

Your tax situation if you have more than one job

If you have more than one job, it is important to make sure you are paying the right amount of tax. Problems can arise because the PAYE (Pay As You Earn) system does not easily cater for multiple jobs.

You only have one tax free personal allowance per tax year and the number of jobs you have does not affect this. In 2021/22, the personal allowance is £12,570. The PAYE system is designed to treat one job as your main employment (against which your personal allowance will be given in full) and the other jobs as secondary (which are taxed at the basic rate of 20%).

This means that you should see a code number of 1257L (reflecting a tax free personal allowance of £12,570 for the tax year 2021/22 with the last digit removed and a letter added) against one job and a BR (basic rate) code against the others.

Example

Agi has two part-time jobs. They both pay her £250 a week. Agi’s tax free personal allowance (weekly amount of £242) is allocated against her first job through the payroll, 20% tax is deducted on every pound from her second job in accordance with code BR. Her weekly tax deductions in 2021/22 are therefore: Job 1: £1.60 (£250 less £242 = £8 x 20%); Job 2: £50 (£250 x 20%).

Income from first job

£13,000

Income from second job

£13,000

Total income

£26,000

Less personal allowance

(£12,570)

Balance subject to 20% tax

£13,430

Tax due

£2,686


At the end of the tax year, we can see from the calculation above, that Agi has paid more or less the right amount of tax, taking into account that her tax-free personal allowance for the year is £12,570.

The tax collected through the payroll for job 1 is £1.60 x 52 = £83.20

The tax collected through the payroll for job 2 is £50 x 52 = £2,600

Total collected = £2,683.20

Why might I pay too little tax when I have more than one job?

Because most people pay tax at 20% (you would have to have total income of over £50,270 in 2021/22 to pay tax at any more than 20%; unless you live in Scotland where the income tax rates and bands are different to the rest of the UK – see the tax basics section for more details), the system outlined above helps ensure that you will not underpay tax.

But this system sometimes falls down. For example, if HMRC are not aware that you have multiple employments, then you may be given the tax-free personal allowance more than once. You will then not have paid enough tax. To prevent this happening, you should make sure HMRC know you have more than one job by always giving your new employer HMRC’s starter checklist (you will not be able to give them a P45 when taking on an extra job). Even when you have told HMRC about your circumstances, you should ensure you check your PAYE coding notices carefully.

You can find information about completing a starter checklist, including an annotated example on our Pay As You Earn (PAYE) form: starter checklist website page.

Getting a tax refund

The way the PAYE system works if you have more than one job means that you might overpay tax if the earnings from your main job actually add up to less than the personal allowance. In this situation you will have paid tax at 20% on too much of your other income.

If this happens to you, you will probably have to wait until the end of the tax year and ask HMRC for a refund, or wait for HMRC to carry out their tax year-end reconciliation process – in which case you should be sent a P800 tax calculation and a repayment in July/August after the end of the tax year.

You can find out more about claiming a refund and HMRC's P800 process in our website guidance What if I pay too much tax?.

Tax credits

Taking another job may help you qualify for working tax credit as by adding the hours together from all your jobs you might meet the hours requirement for your age and circumstances (this will be either 16, 24 or 30 hours depending on your situation). If the extra job means you work at least 30 hours a week, you may get an extra amount added to your tax credit award.

However, if you already qualify for working tax credit, then increasing the number of hours you work (and income) may mean a reduction to your tax credit award overall because the extra income you receive from working more hours may affect the amount of tax credits you can get. If your household income is £6,565 or below (2021/22), you will get the maximum amount for each working tax credit element you qualify for. Anything you earn above that will reduce the amount you can get by 41p for every £1 (but to help keep the system simple, you are allowed to earn up to £2,500 extra before your credits are reduced in the current tax year).

You can find more about tax credits in our tax credits section.

Universal credit

Tax credits are being replaced by universal credit and you may now have to claim universal credit. Unlike working tax credit, for universal credit, you do not need to work a minimum number of hours to qualify but there may be a minimum amount that you are expected to earn. This will be agreed between you and your work coach, as part of your Claimant Commitment.

How much universal credit you actually get in an assessment period will be based on the total amount of earnings you receive in that assessment period. The Department for Work and Pensions (DWP) (who administer universal credit) will normally get information about your earnings across all your jobs from your employers through HMRC’s Real Time Information (RTI) system. After you reach the appropriate work allowance (this is how much money you can earn without it affecting your universal credit payment), for every £1 you earn over your allowance, 63p will be taken away from your total universal credit award.

You can find out more about universal credit on our website RevenueBenefits.

To work out how much universal credit you might get in various scenarios, we suggest you seek a benefits review from Citizens Advice or use one of benefits calculators referred to on GOV.UK. This would be sensible in any case, as your increased hours (and income levels) may have other consequences that you should be aware of, for example, it may affect any other means-tested benefits you claim.

Auto-enrolment: workplace pensions

Employers must automatically enrol all staff who, amongst other things, are aged from 22 to state pension age and earn over £10,000 a year (£833 a month, £192 a week). If you have more than one job then each of your employers will have to check whether you are eligible for that employment separately. This may mean that no employer needs to enrol you in a workplace pension scheme, although overall you may earn more than £10,000 per year.

On the other hand, you may be eligible in one but not the other, or both. If you are eligible in both, then you should be automatically enrolled in both workplace pension schemes (although you can decide to opt out). The contribution amounts involved are likely to be smaller than if you earned all your income from one job, because the first £6,240 of earnings in each employment are not included in the calculations.

⚠️ Please note that you may be able to opt in to a workplace pension even if you are not auto-enrolled.

Further information can be found on our page What is auto enrolment for employees?.

Student loan repayments

From 6 April 2021 the income threshold for starting to make Plan 1 repayments is £19,895 a year (£1,657.91 a month or £382.59 a week). The threshold for a Plan 2 loan is £27,295 a year (£2,274.58 a month or £524.90 per week). The threshold for a Plan 4 loan is £25,000 a year (£2,083.33 a month or £480.76 per week). Once your income goes above the threshold, your employer will deduct 9% of your income that is above the threshold and pay it to HMRC. There is a different threshold and rate for postgraduate loans.

Each separate employer you have will give you a full repayment threshold. If, however, you have to complete a tax return for whatever reason, for example because you are self-employed, HMRC will calculate the loan repayments you owe for the whole year, taking account of all of your earned income and charging the relevant percentage on all income above the threshold. If you receive unearned income (such as rent or interest from savings) of over £2,000 a tax year, then all of this unearned income will be used when calculating loan repayments at the relevant percentage whether or not your earned income is above the repayment threshold. HMRC will take account of the deductions already made by your employers during the year, but it is likely there will be more to pay.

Example

Tanve has a Plan 1 loan and earns £10,000 in one job and a further £10,000 in a second job. As neither amount is over the £19,895 threshold, neither employer will collect student loan repayments. However, if HMRC send Tanve a Self Assessment form, they would expect her to make a repayment based on: £10,000 + £10,000 = £20,000 - £19,895 (the Plan 1 repayment threshold) = £105. She would pay 9% of £105 = £9.45 for that tax year.

If you do not need to complete a tax return, you will not have to make further repayments beyond those already taken by your employers. See our Students section covering student loans.

Statutory sick pay (SSP)/statutory maternity pay (SMP)

If you have more than one job, you may qualify for SSP and SMP in all of them provided you earn above the Lower Earnings Limit (LEL) for National Insurance contributions in each job and meet the other conditions. You can find out more about SSP and SMP on GOV.UK.

Other considerations if you have multiple jobs

Is another job going to cause problems with your employer?

You should make sure that your contracts do not prevent you taking on more work – it could be seen as a conflict of interest, for example. Even if there is nothing in your contracts, it is generally good practice to be open with your employers about having more than one job.

Understand your employment rights, for example that you get at least the National Minimum Wage or National Living Wage for each job

You and your employer can agree to any terms you want, but you cannot agree to any terms that give you less than the rights you have under law.

Working hours

By law, most workers cannot be compelled to work more than an average of 48 hours per week. If you are over 18, you can opt out of this, and may need to do so if you want to take on more than one job.

You can find more information about all of these things on GOV.UK.

What if I have another job but it is from self-employment?

If you have another job but it is on a self-employed basis then you will need to tell HMRC about this by a certain deadline (the 5th October following the end of the tax year in which you started to work for yourself) and complete an annual Self Assessment tax return. You can find out more on our self-employment page.
