The short answer
- Universal Credit falls by 55p for every £1 of take-home pay above your work allowance.
- If you have children or a health condition, the first £427 a month (with help for rent) or £710 (without) is ignored.
- Once you also pay Income Tax and National Insurance, you keep about 32p of each extra pound of gross pay.
- A pound paid into a pension costs you only about 32p, which makes pension saving unusually cheap on Universal Credit.
How the taper works
Each month, Universal Credit starts from your maximum award, the total of your standard allowance and any elements for children, rent, health, caring and childcare. It then takes off 55% of your take-home pay above your work allowance. What is left is your award.
The taper uses take-home pay, not gross pay. That means earnings after Income Tax, National Insurance and pension contributions. Your employer reports what they paid you each month through the PAYE system and the Department for Work and Pensions uses that figure automatically.
The taper is a straight line
There are no cliff edges in Universal Credit. Every extra pound of take-home pay reduces the award by the same 55p until the award reaches zero. That is a big change from the old tax credits and Jobseeker’s Allowance, where working 16 hours or 30 hours could make a sudden difference.
The work allowance
Only some households get a work allowance. You get one if your claim includes:
- a child or qualifying young person; or
- limited capability for work, with or without work-related activity.
- Work allowance
- £427 a month
- Applies when
- Your award includes help with rent
- Work allowance
- £710 a month
- Applies when
- You own your home or pay no rent
- Work allowance
- None
- Effect
- The taper starts at the first £1
A couple has one work allowance between them, not one each. If one partner’s pay already uses it up, every pound the other earns is tapered from the start.
Adding tax and National Insurance
In 2026/27 Income Tax and National Insurance both start at £12,570 a year, about £1,047.50 a month. Above that, a basic-rate taxpayer in England, Wales or Northern Ireland pays 20% tax and 8% National Insurance, so £1 of gross pay becomes 72p of take-home pay. Universal Credit then takes 55% of that 72p.
- Extra gross pay£100.00
- Income Tax at 20%−£20.00
- National Insurance at 8%−£8.00
- Extra take-home pay£72.00
- Universal Credit taper, 55% of £72−£39.60
That is an effective tax rate of 67.6%, higher than the 45% additional rate of Income Tax. It is the price of a system that pays help to people in work, rather than stopping it the moment they find a job.
What extra hours are worth
Take a single parent with one child, no rent to pay and the National Living Wage of £12.71 an hour. Their maximum award is £728.84 a month and their work allowance is £710.
| Hours a week | Gross pay | Take-home | Universal Credit | Total a month |
|---|---|---|---|---|
| 0 | £0 | £0 | £728.84 | £728.84 |
| 8 | £440.61 | £440.61 | £728.84 | £1,169.45 |
| 16 | £881.23 | £881.23 | £634.67 | £1,515.89 |
| 24 | £1,321.84 | £1,245.02 | £434.58 | £1,679.60 |
| 30 | £1,652.30 | £1,482.96 | £303.71 | £1,786.67 |
| 37.5 | £2,065.38 | £1,780.37 | £140.14 | £1,920.51 |
The first 8 hours are worth their full £440.61, because the pay sits inside the work allowance. Going from 16 to 24 hours adds £440.61 of gross pay but only £163.71 of income, 37p in the pound. Going from 30 to 37.5 hours adds £413.08 but only £133.84, or 32p in the pound. Universal Credit for this family would stop at about 44 hours a week.
Your real rate of withdrawal
How much of an extra pound you keep depends on where your pay sits:
| Your situation | You keep |
|---|---|
| Pay within your work allowance | 100p |
| Above the work allowance, below the tax threshold | 45p |
| Above the work allowance and the tax threshold | 32p |
| Off Universal Credit, basic-rate taxpayer | 72p |
Scottish taxpayers pay slightly different Income Tax rates, from 19% to 21% in the bands most claimants fall into, so their figure is a little either side of 32p. Student loan repayments, which start at different thresholds depending on your plan, reduce it further.
Pension contributions on Universal Credit
Because Universal Credit counts pay after pension contributions, the same high withdrawal rate works in reverse when you save into a pension. For a basic-rate taxpayer, putting £100 a month into a workplace pension through salary sacrifice reduces take-home pay by £72, but Universal Credit rises by £39.60. Household income falls by only £32.40.
- Pension contribution£100.00
- Take-home pay falls by−£72.00
- Universal Credit rises by+£39.60
Your employer usually adds a contribution of their own on top. Auto-enrolment means most employees aged 22 or over earning more than £10,000 a year are already saving 5% of qualifying earnings. Opting out would raise take-home pay but cut your Universal Credit, so you would gain far less than the contribution.
Couples and second earners
A couple’s earnings are added together. There is one work allowance and one taper for the household. The first partner’s pay usually uses up the work allowance, so a second earner faces the 55% taper on their first pound, on top of tax once they pass £12,570 a year.
The second earner’s pay can still be worthwhile. It may unlock help with childcare, which pays back 85% of costs only when both partners work. It also lifts the household above the £881 a month earnings threshold for the benefit cap, which can be worth far more than the taper takes away.
Self-employed claimants
If you are self-employed, you report your income and allowable expenses each month and the taper applies to the profit. After a 12-month start-up period, the minimum income floor may treat you as earning at least the National Living Wage for the hours you are expected to work, usually 35 a week, less tax and National Insurance. Earning less than that does not raise your award.
Losses and surplus earnings from earlier months can be carried forward, so a good month followed by a poor one can affect your award for several months.
Paydays and assessment periods
Universal Credit is worked out on what you were paid in each monthly assessment period, not on what you earned in it. A one-off bonus or overtime payment reduces that month’s award by 55p in the pound and the award returns the next month.
Weekly and four-weekly pay
If you are paid every four weeks, once a year two paydays fall in one assessment period. The award drops sharply that month and you may get nothing. It is not lost for good: the next month is based on one payday again.
If a payday moves because of a weekend or bank holiday, tell the Department for Work and Pensions through your journal. In some cases they can treat the pay as belonging to the right month.
Earning your way off Universal Credit
Your award reaches zero when 55% of your take-home pay above the work allowance equals your maximum award. The point varies widely. For a single person with no children and £500 of rent, it comes at about £1,682 of take-home pay, or £1,928 gross, which is a 35-hour week at the National Living Wage.
If your earnings take you to zero, the claim stays open for up to six assessment periods. If your pay falls again in that time, payments restart without a new claim. That makes it safer to try a better-paid job or more hours.
The taper and the benefit cap
The benefit cap limits the total of most benefits for households not in work. Earning £881 a month or more after tax removes it completely. Sixteen hours a week at the £12.71 National Living Wage is £881.23 a month, enough to clear it.
For a capped household, those first hours can be worth more than the pay itself. The benefit cap calculator shows the effect for your household.
Childcare costs and working more
Extra hours often mean extra childcare. Universal Credit pays back 85% of registered childcare costs, up to £1,071.09 a month for one child, and this is added to your maximum award before the taper is applied.
- Universal Credit without childcare costs£434.58
- Childcare element, 85% of £400+£340.00
- Universal Credit with childcare costs£774.58
- Childcare paid out−£400.00
So the childcare costs this parent £60 a month, not £400. Report the costs in your journal in the assessment period you pay them, with a receipt or invoice, or they will not be included.
A pay rise or more hours
The taper treats every extra pound the same way, whether it comes from more hours, overtime or a higher hourly rate. A rise from £12.71 to £13.50 an hour on a 30-hour week adds £102.70 of gross pay a month. After tax, National Insurance and the taper, the household is £33.27 better off, about 32p in the pound.
A pay rise has one advantage: it brings no extra travel or childcare costs. Extra hours can bring both, so add those to the calculation before you decide.
A second earner in numbers
Take a couple with two children and social rent of £700, where one partner already takes home £1,200 a month. If the other partner starts 16 hours a week at the National Living Wage, earning £881.23 a month, their Universal Credit falls from £1,549.70 to £1,065.03.
The household is £396.55 a month better off, which is 45p of each pound earned. Their pay is under the tax threshold, so only the taper applies.
Planning your hours
- Work out your work allowance. Earnings inside it are yours to keep in full.
- Check whether reaching £881 a month would lift the benefit cap for your household.
- Add in childcare and travel costs, remembering the 85% childcare element.
- Consider paying more into a workplace pension, which costs you about a third of its value.
- Think about the timing of paydays, especially if you are paid weekly or four-weekly.
