Short answer
Tax-Free Childcare is a UK-wide scheme. The £100,000 ceiling applies to each partner’s expected adjusted net income separately: if either person expects to be over it, the income condition is not met. Exactly £100,000 is not over the limit, but it does not prove full eligibility.
Check both partnersThe income rule applies to each partner
GOV.UK says you cannot claim if you or your partner expects adjusted net income, including relevant foreign income, to be over £100,000 for the current tax year. It is not a combined-household limit: two partners at £90,000 each are within this income condition, while one partner at £100,001 is over it. Exactly £100,000 is at the limit, not over.
Use adjusted net income, not headline salary
Adjusted net income starts with taxable income before Personal Allowance and includes items such as taxable benefits, self-employed profit, interest, dividends and rental profit. Qualifying Gift Aid and pension adjustments can reduce it. P60 taxable pay may already reflect salary sacrifice or a net-pay pension, so the same payroll reduction must not be deducted again.
What this does — and does not — establish
Meeting the upper-income condition is not a full eligibility decision. Work and minimum earnings, child age, approved provider, immigration status, interactions with Universal Credit or vouchers, and three-month reconfirmation still matter. If eligible, the government adds £2 for each £8 paid in, capped at £500 every three months and £2,000 a year per child; the disabled-child caps are double.
