Universal Credit Minimum Income Floor Calculator
The Minimum Income Floor (MIF) applies to self-employed Universal Credit claimants who have been self-employed for more than 12 months. UC assumes you earn at least NMW × expected hours, even if actual earnings are lower.
Frequently Asked Questions
What is the Universal Credit Minimum Income Floor?
The Minimum Income Floor (MIF) is a UC rule that assumes self-employed claimants earn at least the equivalent of the National Living Wage × their expected weekly hours. If actual profits are below this threshold, UC is calculated as if they earned the MIF, reducing their UC award.
When does the MIF apply?
The MIF applies to self-employed UC claimants who have been trading for more than 12 months (the 'start-up period' grace). During the first 12 months of self-employment, actual earnings are used regardless.
Why does the MIF exist?
The MIF was designed to incentivise self-employed people to grow their business or take alternative employment if their self-employment is not financially viable. It prevents UC from indefinitely topping up very low self-employment income.
What is the UC taper rate?
The UC taper rate is 55% — for every £1 of earnings above the Work Allowance, UC is reduced by 55p. This means the UC award gradually reduces as earnings increase, rather than stopping abruptly at a threshold.
What is the UC Work Allowance?
The Work Allowance is the amount you can earn before the 55% taper starts. For 2025/26: £404/month if you receive housing costs in UC; £673/month if you don't receive housing costs. Self-employed people with a child or disability element qualify for a Work Allowance.
Who is exempt from the Minimum Income Floor?
Exemptions include: new self-employed claimants in the first 12 months; claimants who are carers for a severely disabled person; claimants who cannot work due to illness or disability; and those with a child under 1 year old.
Can I dispute the MIF if my income is genuinely low?
The MIF is a fixed rule, not something you can dispute on the basis of low income alone. If your self-employment falls below MIF-equivalent earnings consistently, DWP may review your self-employment status and whether gainful self-employment conditions are met.
What counts as profit for UC self-employment?
UC self-employment profit is calculated monthly as business receipts minus allowable expenses. Capital expenditure uses flat-rate simplifications (mileage rates, simplified expenses). HMRC's cash basis accounting rules largely apply.
Does the MIF apply to partnerships?
Each partner in a self-employed partnership is assessed individually for UC. The MIF applies to each partner's share of profits. If one partner earns above MIF and one below, the lower-earning partner is subject to MIF.
How does UC handle irregular self-employment income?
UC is calculated monthly. If income fluctuates significantly between months, UC fluctuates accordingly. There is no averaging across months for UC purposes (unlike HMRC averaging). High-income months reduce UC; low-income months (subject to MIF) reduce the award less.
What are gainful self-employment conditions?
DWP assesses whether your self-employment is 'gainful' — organised, developed, regular, and in the expectation of profit. If they conclude it is not, the MIF may not apply (but your UC may also be reduced to treat you as unemployed, reducing your payment further).
Does minimum income floor apply to UC childcare costs?
Childcare cost support within UC (up to 85% of eligible childcare costs) is based on actual earnings, not MIF. The MIF affects the UC standard allowance taper, but childcare costs are separately calculated based on actual childcare payments made.
