Universal Credit & Working: The 55p Taper Rate Explained (2025-26)
Universal Credit (UC) is designed to make work pay — but the interaction between UC, income tax, and National Insurance creates very high effective marginal rates for some workers. Understanding the taper rate helps you work out exactly how much of a pay rise or extra hours you actually keep.
What is the taper rate?
The UC taper rate is the rate at which your Universal Credit award reduces as your earnings rise. Since October 2021, the taper rate has been 55% — meaning UC reduces by 55p for every £1 of net earnings above your work allowance.
Work allowance: the earnings buffer
The work allowance is the amount you can earn before the taper kicks in. It only applies if you have a child or a limited capability for work (health condition):
- Higher work allowance (no housing costs in UC): £673/month
- Lower work allowance (housing costs in UC): £404/month
If you have no children and no health condition limiting work, there is no work allowance — the 55% taper applies from the first pound of earnings.
Effective marginal rate while on UC
For a Basic Rate taxpayer with no work allowance, each extra pound earned results in:
- Income tax deducted: 20p
- National Insurance deducted: 8p
- UC reduced: 55p of the remaining 72p net earnings = approximately 40p
Total withdrawn per £1 gross earned: approximately 68p, leaving you 32p. This is an effective marginal rate of approximately 68%.
Example: single person, no children, earning £1,200/month
| Item | Amount |
|---|---|
| Gross earnings | £1,200/month |
| Estimated net earnings after tax & NI | ~£1,047/month |
| Work allowance (assume nil) | £0 |
| UC taper (55% of £1,047) | -£576 |
| UC reduction | £576/month |
The claimant keeps the full increase in earnings but their UC falls significantly, cushioning the gain. Once earnings rise above the point where UC reaches £0, the claimant falls off UC entirely and faces a potential cliff edge if they also lose other passported benefits (free prescriptions, council tax reduction, etc.).
The UC cliff edge
Some workers are cautious about increasing their hours or taking a promotion because they fear losing passported benefits at the point where their UC entitlement reaches zero. This is a real concern — the abrupt loss of free prescriptions, dental care, and council tax reduction can more than offset a modest earnings increase.
Frequently asked questions
Does the taper apply to all income?
The taper applies to net earned income (after income tax and NI). It also applies to self-employment profits. Some income types are disregarded entirely — such as child benefit (though child benefit itself interacts with the High Income Child Benefit tax charge at higher incomes).
Has the taper rate ever been higher?
Yes. Until October 2021, the UC taper rate was 63%. The reduction to 55% was announced at the October 2021 Budget and was intended to improve work incentives for UC claimants.
