Introduce joint income taxation for a household

Background

We would like to urge the government to revise the UK tax system to allow married couples, civil partners or cohabitants to file income tax jointly, enabling household-level assessment instead of individual assessment.

Additional details

The current UK system penalises couples with unequal incomes. Joint taxation would benefit families, encourage financial equality and fairness. Avoiding the £100k personal allowance trap, this is especially attractive for families where one parent stays at home or works part-time. It would support family stability and child welfare, encourage workforce flexibility without penalising families, and improve labour market participation.
