The first month after a wedding is a good time to sort out the money admin, while the paperwork is still on the table. None of this needs to be done in one evening, but some items have deadlines.
1. Health insurance: check the window
In the US, marriage is usually a qualifying life event: you often have 30 days with an employer plan and 60 days on the marketplace to add a spouse or switch plans. Compare total yearly cost (premiums plus likely out-of-pocket), not just the premium.
2. Update beneficiaries
Retirement accounts and life insurance follow the beneficiary form, not your will. Update each one.
3. Review tax withholding
Two incomes on a joint return can push the combined tax above what each paycheck withholds. In the US, update your W-4 so April isn't a surprise.
4. Pick a way to share costs
Three common setups: 50/50, proportional to income, or one shared pot. Proportional often feels fairest when incomes differ a lot.
5. Finish the wedding budget
List any remaining vendor balances and the card they're on, and pay those first before new spending starts.
6. Set one shared goal
An emergency fund for the household, a holiday or a home deposit. One shared number makes the monthly check-in easier.
