How to switch to joint assessment

In myAccount, under your personal details, or by contacting Revenue.

Joint assessment usually starts by itself from the year after you marry. If you're on single assessment, either of you can choose joint assessment in myAccount. You also choose who is the assessable spouse (the one taxed on both incomes). Your choice applies for that year and the years after.
