Money Decisions at Life's Turning Points: Marriage, Kids, Moves, Divorce, and Windfalls
1 / 8
Which life changes affect a financial plan the most?
- Marriage, a new child, a move or home purchase, a job change, divorce, and a sudden increase in income or wealth usually matter most.
- Each can change your tax bracket, insurance needs, cash reserves, and who depends on your income.
- Many also reset employer benefits and equity deadlines, which are easy to miss.
- A short checklist review at each turning point tends to catch more than an annual review alone.

- Each can change your tax bracket, insurance needs, cash reserves, and who depends on your income.

What changes when you marry?
- Married filing separately limits several credits and deductions, so comparing it with a joint return is worth doing when circumstances change.
- Beneficiary designations on retirement accounts, life insurance, and transfer-on-death accounts pass assets directly, so updating them matters as much as a will.
- A spouse is generally the default beneficiary of a 401(k) unless they consent in writing to someone else.
- In community property states such as California, most assets acquired during marriage are owned jointly, which affects taxes and estate plans.
Children and education
- Life and disability coverage often need a fresh look once someone depends on your income, and a will naming a guardian is the core legal step.
- For 2026, the child tax credit is $2,200 per child, phasing out above $200,000 of income ($400,000 joint), and dependent care FSAs allow $7,500 per household.
- 529 plans grow tax-free for qualified education costs; non-qualified withdrawals owe tax plus a 10% penalty on earnings.
- From 2026, a 529 can cover up to $20,000 a year of K-12 expenses per beneficiary.
- Unused 529 money can move to the beneficiary's Roth IRA, up to $35,000 lifetime, if the account is at least 15 years old and other rules are met.
A home purchase or a move
- Lenders look at debt-to-income ratios, but a comfortable payment also depends on childcare, savings goals, and job stability.
- Moving states can change how equity compensation is taxed, since states may tax options and RSUs earned while you worked there.
- Selling a primary home can exclude up to $250,000 of gain ($500,000 joint) if ownership and use tests are met.
- Keeping a larger cash reserve after closing can help absorb repairs and other surprises.
What happens to equity and savings when your job changes?
- Unvested awards are usually forfeited when you leave, so the timing of a departure relative to vesting dates matters.
- Vested options often must be exercised within about 90 days, and ISOs not exercised within three months of leaving lose ISO tax treatment.
- An old 401(k) can stay put, move to a new plan, or roll to an IRA; a direct rollover avoids the 20% mandatory withholding.
- Leave policies can pause or continue vesting, so plan documents are worth checking before parental or other leave begins.
Divorce and dividing assets
- Transfers between spouses incident to divorce are generally not taxable, and the recipient takes over the original cost basis.
- Because basis and tax status carry over, assets of equal value can carry very different future tax bills, such as a pre-tax 401(k) versus a Roth IRA.
- Dividing a 401(k) or pension generally requires a qualified domestic relations order; IRAs can be split by a transfer under the divorce decree.
- For divorce agreements executed after 2018, alimony is neither deductible by the payer nor taxable to the recipient.
- How options and unvested RSUs are divided depends on state law and the settlement, and beneficiaries and estate documents need updating once it is final.
What about an inheritance, raise, or windfall?
- Inheritances generally are not income to the recipient, and most inherited assets take a basis equal to their value at death.
- Most non-spouse beneficiaries must empty an inherited IRA within 10 years, with annual withdrawals also required if the owner had begun required distributions.
- Salary, bonuses, and vested RSUs are ordinary income taxed up to 37% federally; long-term gains face 0%, 15%, or 20%, plus 3.8% NIIT at higher incomes.
- Setting aside the likely tax bill, and pausing before large decisions, leaves room to fit new money into the plan.
Key takeaways
- Treat each major life event as a trigger to review insurance, beneficiaries, taxes, and savings.
- Divorce and inheritance carry basis and account rules that make equal-looking assets unequal after tax.
- Know the tax character of new money before deciding what to do with it.
- Check equity deadlines before changing jobs, and confirm tax and legal details with a CPA or attorney.
