How to Plan for an Inheritance When You Already Have High Income

Inheritance Is Not Income (Usually)

Most inherited assets are not taxable income. You can inherit $5 million in cash, stocks, and real estate without owing a single dollar in federal income tax on the transfer itself. The IRS treats inheritances differently from gifts, wages, and investment gains. There is no "inheritance tax" at the federal level for the recipient.

But there is a massive exception that catches high earners off guard: inherited retirement accounts. Traditional IRAs, 401(k)s, 403(b)s, and annuities are all classified as "income in respect of a decedent" (IRD). Every dollar you withdraw from these accounts is taxed as ordinary income, at your marginal rate. For someone already earning $300,000 to $600,000, that marginal rate is 35% or 37%. Inherited retirement accounts are where the real damage happens, and where planning matters most.

The Stepped Up Basis: The Most Powerful Tax Provision You Will Ever Use

When you inherit appreciated assets (stocks, ETFs, real estate, business interests), the IRS resets the cost basis to the fair market value on the date of death. This is called the stepped up basis, and it is arguably the single most valuable tax provision in the entire Internal Revenue Code.

Here is why it matters. Your parent bought 1,000 shares of Apple at $10 per share ($10,000 total investment). At the time of death, those shares are worth $200 each ($200,000 total). If your parent had sold during their lifetime, they would owe capital gains tax on $190,000 of gain. But because you inherited the shares, your cost basis is $200,000. You can sell immediately for $200,000 and owe zero capital gains tax. The $190,000 in appreciation is permanently erased from the tax system.

This applies to all inherited capital assets: individual stocks, mutual funds, ETFs, real estate, business interests, and collectibles. For inherited real estate, the stepped up basis also resets the depreciation schedule, which matters enormously if the property is a rental.

Critical action: identify every inherited asset that receives a stepped up basis, obtain a date of death valuation (your estate attorney or CPA can help), and document these basis figures permanently. If you sell inherited assets years later without proper basis documentation, you may end up paying capital gains tax you never owed.

The Inherited IRA Time Bomb

The SECURE Act of 2019 fundamentally changed the rules for inherited retirement accounts. Before SECURE, non spouse beneficiaries could "stretch" distributions from an inherited IRA over their own life expectancy, sometimes spanning 30 to 50 years. That option is gone.

Under current law, most non spouse beneficiaries must fully empty an inherited IRA within 10 years of the original owner's death. There are exceptions for surviving spouses, minor children (until age 21), disabled or chronically ill beneficiaries, and beneficiaries who are not more than 10 years younger than the decedent. Everyone else faces the 10 year rule.

For a high earner, this creates a compounding tax problem. A $1 million inherited traditional IRA must produce at least $100,000 per year in taxable distributions over 10 years. That $100,000 stacks directly on top of your existing income, pushing you deeper into the 35% and 37% brackets and potentially triggering additional Medicare surtaxes.

The IRS also issued final regulations in 2024 clarifying that if the original account owner had already begun required minimum distributions (generally after age 73), the beneficiary must take annual distributions during the 10 year period, not just empty the account by year 10. Missing these annual distributions triggers a 25% penalty on the amount that should have been withdrawn.

A Concrete Scenario: The $296,000 Tax Bill

Consider a software engineer earning $400,000 annually who inherits two assets from a parent: an $800,000 traditional IRA and $500,000 in a taxable brokerage account (individual stocks and ETFs).

The taxable brokerage account receives a full stepped up basis. The parent's original cost basis was $180,000, but that is irrelevant. The beneficiary's basis is $500,000. If sold immediately, the capital gain is $0. This $500,000 is effectively tax free.

The inherited IRA is a different story. Distributing $80,000 per year over 10 years pushes the engineer's AGI from $400,000 to $480,000. The additional federal income tax on that $80,000 is approximately $29,600 per year (at blended rates including the 35% and 37% brackets, plus the 0.9% Additional Medicare Tax). Over 10 years, the total federal tax bill on the inherited IRA is approximately $296,000.

Strategies to Reduce That Bill

The $296,000 is not inevitable. Several approaches can meaningfully reduce it:

1. Uneven distribution timing. You are not required to take equal distributions each year (unless annual RMDs apply). If you take a sabbatical, change jobs, start a company, or have any year with lower W2 income, pull larger IRA distributions in that year. The difference between the 37% bracket and the 24% bracket on $80,000 is $10,400 in tax savings for that single year.

2. Charitable giving pairing. If you are charitably inclined, use a donor advised fund (DAF) seeded with inherited IRA distributions. The charitable deduction offsets the IRA income. A $50,000 DAF contribution in a year you take $80,000 from the inherited IRA effectively reduces the taxable impact to $30,000. If you are over age 70.5, qualified charitable distributions (QCDs) directly from the inherited IRA are even more efficient, though annual limits apply.

3. Roth conversion stacking. In a lower income year, you could take larger inherited IRA distributions and simultaneously convert some of your own traditional IRA to Roth. The tax hit is real in that year, but you are paying at a lower rate than you would in a full income year, and the Roth grows tax free permanently.

4. State tax arbitrage. If you are considering a move from a high tax state (California, New York, New Jersey) to a no income tax state (Texas, Florida, Washington, Nevada), the timing of that move relative to inherited IRA distributions can save 10% or more on every dollar distributed.

Coordinating with Equity Compensation

For tech employees with RSU vests, stock option exercises, or ESPP purchases, inherited IRA distributions create a dangerous stacking problem. Every additional dollar of ordinary income pushes against the same marginal brackets.

The key principle is never stack voluntarily. If you know a large RSU vest is hitting in Q4, do not take inherited IRA distributions in Q4 of the same year if you can avoid it. Front load distributions to Q1 or Q2 of a year when you have more bracket room, or defer to a year when your equity compensation is lighter.

If you are planning an ISO exercise or an NQO exercise, model the combined income impact before executing. An $80,000 inherited IRA distribution plus a $200,000 NQO exercise plus your $400,000 salary puts you at $680,000 in ordinary income. At that level, every dollar above $609,350 (single, 2026) is taxed at 37% federally, plus state taxes, plus the 0.9% Additional Medicare Tax.

Practical approach: build a multi year income projection that maps RSU vesting schedules, expected option exercises, and inherited IRA distribution targets. Identify the "valley" years where total income will be lowest, and concentrate inherited IRA distributions there.

Inherited Real Estate: Sell, Hold, or Exchange

Real estate inheritance comes with the same stepped up basis benefit as stocks. A property purchased by your parent for $250,000 that is worth $900,000 at death has a new basis of $900,000. You can sell for $900,000 and owe no capital gains tax.

The Decision Framework

Sell immediately if: you do not want to be a landlord, the property is in a different state, it needs significant capital investment, or you simply want to deploy the proceeds into a diversified portfolio. The stepped up basis makes an immediate sale extraordinarily tax efficient. This window of opportunity will never be more favorable.

Hold as a rental if: the property generates strong cash flow (6%+ cap rate after realistic expenses), you want real estate exposure, and you can handle the management burden. Be aware that rental income stacks on top of your W2 income, and the $25,000 passive loss allowance phases out completely at $150,000 AGI, which means you are almost certainly above the threshold.

1031 exchange if: you want to stay invested in real estate but want a different property (different location, different type, professional management). Because your basis was just stepped up, a 1031 exchange preserves the stepped up basis and defers any future gains. This is strategically powerful if the inherited property is a single family home you want to trade into a professionally managed multifamily or commercial property.

The Emotional Dimension: Do Nothing for Six to Twelve Months

Inheritance arrives during grief. Family members may have opinions about what should happen with the money. There may be pressure to invest, to spend, to share, or to make decisions immediately.

The best financial advice for someone who just received an inheritance is almost always: do nothing consequential for 6 to 12 months. Park cash in Treasury bills or a high yield savings account earning 4% to 5%. Leave inherited investments where they are (document the stepped up basis, but do not sell unless there is a specific tax reason to act quickly). Let the emotional weight of the loss settle before making six or seven figure financial decisions.

The one exception is the inherited IRA. If the original owner was already taking required minimum distributions, you must continue annual distributions. Calculate the required amount, take it, and set the cash aside. Everything else can wait.

Estate Planning for the Next Generation

If you earn $400,000+ and just inherited $1 million or more, your own estate may now exceed or approach the federal estate tax exemption. The current exemption is $13.99 million per individual ($27.98 million per married couple) in 2026, but this is scheduled to be cut roughly in half on January 1, 2026 when the Tax Cuts and Jobs Act provisions sunset (unless Congress acts to extend them).

Use the inheritance as a trigger to review your own estate plan. Specifically:

1. Update your estate tax projections. Add the inherited assets to your existing net worth and model growth over 10, 20, and 30 years. If your estate is projected to exceed the exemption, the planning window is now.

2. Fund irrevocable trusts. If you have children, consider using a portion of the inheritance to fund irrevocable life insurance trusts (ILITs) or spousal lifetime access trusts (SLATs) while the exemption is high.

3. Review beneficiary designations. An inheritance often reshuffles the financial picture. Make sure your own 401(k), IRA, and life insurance beneficiary designations are current and aligned with your estate plan.

4. Consider a dynasty trust. If the combined value of your earned wealth and inheritance is substantial ($5 million+), a dynasty trust can protect assets from estate taxes for multiple generations while still providing for your children and grandchildren.

The worst outcome is inheriting significant wealth, failing to plan, and then having your own estate face the same tax erosion that a proper plan could have prevented. The inheritance is not just an asset; it is a signal that your financial complexity has permanently increased, and your planning must increase to match.
