Beneficiary Updates (Critical)

| IRA / Roth IRA | Brokerage (Fidelity, Schwab, Vanguard, etc.) |
| Life insurance | Insurance company |
| Bank accounts | Your bank (add payable-on-death beneficiary) |

Important: 401(k) plans legally require your spouse as beneficiary unless they sign a waiver.
How to Manage Money as a Couple
| Approach | How It Works | Best For |
|---|---|---|
| Fully combined | All income goes into joint accounts | Couples with similar spending habits and full trust |
| Fully separate | Each person manages their own money; split bills | Couples with very different incomes/spending styles or second marriages |
| Hybrid (most popular) | Joint account for shared expenses; personal accounts for discretionary spending | Most couples—balances teamwork and autonomy |
Hybrid Approach Example (Combined Income $150,000)
| Account | Purpose | Monthly Funding |
|---|---|---|
| Joint checking | Rent/mortgage, utilities, groceries, insurance | $4,500 (proportional to income) |
| Joint savings | Emergency fund, vacation, shared goals | $1,000 |
| Joint investment | Retirement, long-term goals | $1,500 |
| Spouse 1 personal | Discretionary spending | $500 |
| Spouse 2 personal | Discretionary spending | $500 |
Tax Filing: Joint vs. Separate
| Factor | Married Filing Jointly | Married Filing Separately |
|---|---|---|
| Standard deduction (2026) | $30,000 | $15,000 each |
| Tax brackets | Wider (more favorable) | Same as single |
| Child Tax Credit | Available | Very limited |
| Student Loan Interest deduction | Available (up to $2,500) | Not available |
| Roth IRA contribution | Full up to $230K AGI | Full up to $10K AGI (effectively zero) |
| Earned Income Tax Credit | Available | Not available |
| Education credits | Available | Not available |
| Best for most couples | Yes | Rarely |
When Filing Separately May Help
| Situation | Why Separate Helps |
|---|---|
| One spouse has high medical expenses | Lower AGI floor for itemizing medical expenses |
| Income-driven student loan repayment | Payment based on one income, not combined |
| One spouse has tax liens/debt | Protects other spouse’s refund |
| Suspected fraud/dishonesty | Limits shared liability |
Insurance Optimization
| Insurance Type | Action After Marriage |
|---|---|
| Health insurance | Compare both employer plans; choose the best one or keep separate if cheaper |
| Auto insurance | Bundle policies for multi-car discount (5-25% savings) |
| Renters/homeowners | Add spouse; review coverage amounts |
| Life insurance | Get/increase coverage (especially if buying a home or planning kids) |
| Umbrella insurance | Consider if combined assets exceed $500K |
| Disability insurance | Review whether employer coverage is adequate for both |
The Bottom Line
The most important financial step after marriage is having an honest conversation about money—debts, goals, spending habits, and how to manage finances together. Update all beneficiaries immediately, decide on a money management approach (hybrid works for most), file taxes jointly (almost always saves money), and create a joint budget with shared goals. Financial alignment is one of the strongest predictors of a lasting marriage.
