Until an inheritance arrives, it is someone else’s money that you cannot spend or count on.
The amount, timing, and form can change. The person whose assets they are may need them for living expenses, care, or other priorities. Build a base plan that works without the transfer, then consider how an actual inheritance could improve it.
Do not turn a family estimate into a current asset
“My parents’ house is worth $500,000” does not establish a $500,000 future payment to you. There may be borrowing, selling costs, other beneficiaries, or a different plan for the property.
The person may also live for many more years and need the resources. Their financial security comes before your expected windfall, so leave a speculative inheritance out of your current net-worth total.
Build the retirement budget without it first
Suppose a hypothetical retirement plan needs $3,500 a month and expected income from other sources is $2,800. That leaves a $700 monthly gap, or $8,400 a year.
If you assume a $100,000 inheritance will fill it, ask what happens if the amount is $30,000, arrives later, or does not arrive at all.
Simply dividing $100,000 by $8,400 gives about 11.9 years before accounting for taxes, investment changes, inflation, or unexpected spending. After that the lump sum is gone and the $700 gap returns.
Social Security works differently: the CFPB’s claiming guide describes it as income for life that is generally adjusted each year for increases in the cost of living. Each month you wait to claim, up to age 70, permanently raises the monthly benefit; for people born after 1960, the benefit ranges from 30% less than the full amount at 62 to 24% more at 70. Choosing when to claim can narrow the $700 gap without relying on anyone’s estate, so weigh that choice against your health, savings, and work plans.
The retirement-income guide helps compare spending with resources you can actually plan around.
Care costs are a real reason the expectation can change
Medicare.gov states that Medicare doesn’t pay for long-term care, and neither does most health insurance, including Medigap. Long-term care includes ongoing help at home, in the community, in assisted living, or in a nursing home, and people pay for most of it themselves. Some qualify for Medicaid under their state’s rules, and others buy private long-term care insurance.
A parent who spends savings on that care is using their money for its purpose, and your plan should already assume the estate can shrink this way.
Talk about plans and documents
A useful conversation may cover whether a plan exists, who to contact in an emergency, and where important documents are kept. The owner decides what to share.
Estate documents, beneficiary designations, taxes, and family circumstances can require professional advice. Do not assume a verbal promise resolves them.
If you provide support to a parent, clarify whether it is a gift or a loan. The CFPB’s family-lending tips suggest writing out what everyone agreed to, including amounts, timing, and repayment, and giving everyone a copy.
If money is actually received, reassess before committing it
Confirm what you received, any restrictions, relevant taxes or deadlines, and whether the asset is cash, property, or a retirement account.
Tax rules differ by form: for inherited property, the IRS says your basis is generally its fair market value on the date of death, and selling for more than that basis produces a taxable gain. For an inherited IRA or workplace plan, IRS rules require many non-spouse beneficiaries to empty the account by the end of the 10th year after the owner’s death, and you must include taxable distributions in your gross income. Spouses, minor children, disabled or chronically ill beneficiaries, and beneficiaries no more than 10 years younger than the owner have other options.
For a material inheritance, qualified legal, tax, or financial help may be worthwhile before you spend any of it.
Then revisit debts, reserves, retirement income, and near-term goals. An inheritance can strengthen a plan without having to become a new house, a bigger lifestyle, or an immediate loan to someone else.
Keep two scenarios
The base scenario should use your income, savings, and realistic goals. A separate inheritance scenario can show what you would do if the transfer occurs.
Make your retirement and borrowing decisions from the base scenario, and open the second one only when money is actually in an account in your name.
