The taper rate: what you keep when you work more

Universal Credit does not stop when you start work. Above your work allowance, every £1 of take-home pay reduces your award by 55p, which means you keep 45p of it plus whatever the pound itself was worth. There is no hours threshold, no cliff edge, and no point at which working an extra shift leaves you worse off on Universal Credit. The award tapers away smoothly until it reaches zero, and if your earnings fall back far enough within five months the payments restart automatically, so a short spell of higher pay does not mean starting again.

Only households with children or with a health element get a work allowance: the amount you can earn each month before the taper starts at all. It is £427.00 if your award includes a housing element and £710.00 if it does not. Everyone else has no allowance and is tapered from their first pound. That single distinction is the biggest driver of how much work pays on Universal Credit, and it is why a health element is worth more than its headline rate.

This is the detail that changes the answer. Universal Credit tapers your pay after income tax, National Insurance and any pension contribution. So on a salary above the personal allowance, an extra £100 of gross pay loses 20% to tax and 8% to National Insurance, leaving £72, and the taper then takes 55% of that, leaving about £32. That combined rate is high, but it is nowhere near the 100% people assume, and every extra pound still leaves you ahead.

Pension contributions are taken off before Universal Credit looks at your earnings, so they reduce your assessed pay and increase your award. On the taper, a £100 pension contribution costs you far less than £100 of take-home pay: you get tax relief, and 55% of the reduction comes back as extra Universal Credit. For anyone on the taper who can afford to contribute at all, it is the most efficient thing they can do with the money.

Earnings are counted in the assessment period your employer reports them, not the period you worked. If you are paid weekly or four-weekly, some periods contain an extra pay date, and the taper treats that as one large month, so the award drops sharply for that month alone and recovers afterwards. The same happens when an employer pays early before Christmas or a bank holiday. Nothing has gone wrong; the money is not lost; but it is worth expecting so it does not derail a budget.
