Supporting couples with children through the tax system Mike Brewer Institute for Fiscal Studies
Outline • Proposals • Perceived structural problems • Impacts
Perceived structural problems • Tax credits are assessed on family income, with no additions for second adult • Some couples treated less generously than if parents (claim to) live apart • Couples need higher earnings than lone parents to escape poverty (£240/wk vs £76/wk in 2004/5) • Income tax individually-assessed, so offers no support to full-time carers • Single-earner couple pays more tax than two-earner couple with same pre-tax earnings • Reflect conflicting policy goals when designing tax system for families: • Whether to redistribute to low-income families or individuals? • Whether to have “couple penalties”, “couple premia”, or neither? • How strong to make work incentives for 1st and 2nd earners? • How to compare poverty risks for lone parents with couples with children?
Which couples would gain?Policies cost around £1bn/yr Figure shows average change in income of couples with children by income decile of whole population
How would it affect incentives? • Incentives to work • Extra WTC for couples encourages 1st earner to work, but discourages 2nd earner • Extra WTC for 2nd earner encourages 2nd earners to work • TPA discourages 2nd earner to work (while children under 6) • Incentives to earn more • The policies that increase WTC mean more couples facing high marginal effective tax rates (METR would rise to typically 70%, from 37%) • TPA increases marginal effective tax rates of person who forgoes PA, reduces METRs of some low-paid beneficiaries. • All policies increase support for couples with children compared to • Couples with no children • Lone parents
