If you changed your name:
- Update Social Security Administration: Get a new Social Security card

Update Your Withholding
This is one of the most important steps after getting married.
Why Update Withholding?
- Marriage changes your tax situation: Different brackets, deductions, credits
- Avoid surprises: Prevent owing money or large refunds
- Optimize cash flow: Get the right amount in each paycheck
How to Update
- Get new W-4 forms: From your employer(s)
- Use IRS Tax Withholding Estimator: Calculate correct withholding
- Consider both incomes: Account for both spouses' income
- Submit updated forms: To your employer(s)
W-4 Considerations
- Married Filing Jointly: Usually the best choice
- Multiple jobs: Use the "Multiple Jobs" worksheet
- Dependents: Account for any dependents
- Other income: Include investment income, side jobs, etc.
Action: Update W-4 forms within a few weeks of getting married.
Choose Your Filing Status
You have two options as a married couple:
Married Filing Jointly (MFJ)
- Most common: Used by 95% of married couples
- Usually better: Lower total tax in most cases
- Higher standard deduction: $30,800 (2026)
- Better brackets: More favorable tax brackets
- Full credits: Access to all credits
Married Filing Separately (MFS)
- Rarely beneficial: Usually results in higher total tax
- Lower standard deduction: $15,400 each
- Limited credits: Many credits not available
- When it might help: One spouse has high medical expenses, legal separation concerns
Recommendation: File jointly unless you've calculated that filing separately saves money (rare).
