Running a home on two paychecks

• Decide which bills each paycheck covers, since the two may land on different days.
• Pick a way to split shared costs, such as 50/50 or in proportion to each income.
• Keep one shared list of bills and due dates so neither of you pays twice or misses one.
• Revisit the split when one income changes.

For childcare, IRS Topic 602 says a married couple must file a joint return, and both spouses must have earned income, to claim the Child and Dependent Care Credit, and the expenses that count are capped at the lower of the two earned incomes.
