Updated July 31, 2026. Quick answer: if you are the sole heir, waive it — the fee is taxable income while the same dollars as inheritance are tax-free, so charging the estate just hands part of your own money to the IRS. If there are multiple heirs, the math flips: the fee comes off the top before the split, so taking it means the other heirs fund most of your compensation, and paying income tax on it can still leave you ahead.
The arithmetic, honestly
Say the statutory fee is $30,000, your marginal rate is 30%, and there are three equal heirs. Take the fee: you net $21,000 after tax, plus your third of the now-smaller estate (−$10,000 to your share) — net gain about $11,000 over waiving. Sole heir: taking it nets $21,000 but shrinks your inheritance by the full $30,000 — a pure $9,000 loss. The break-even sits wherever your share of the estate times the fee equals the after-tax fee; more co-heirs and lower brackets favor taking it, sole-heir status almost never does.
Three wrinkles worth knowing before deciding
The decision has a deadline in practice — waivers are cleanest documented early, before the fee accrues under state law. A fee can be justified even among family when one sibling does years of real work; the tax cost is the price of fairness, and courts in reasonable-compensation states weigh documented hours heavily. And the fee is deductible to the estate only when the estate itself owes income or estate tax — on most estates it deducts nothing, so there is no offsetting benefit.

The number that surprises people who bought a long time ago
Downsizing is the one home sale where the gain is usually large and the exclusion usually still covers it. A couple who bought in 1994 for $180,000 and sell at $760,000 with $46,000 of selling costs have a realized gain of about $534,000 before improvements. That is above the $500,000 joint cap — but decades of capital improvements are exactly what brings it back under, and most sellers have never added them up.
Improvements are the lever, and the records are the constraint
A new roof, an addition, a replaced HVAC system, new windows, a finished basement: these add to basis. Repainting and repairs do not. Thirty years of improvements on a family home routinely total six figures, and every dollar of it reduces the gain dollar for dollar. The practical problem is documentary, not legal — the seller who kept receipts pays less than the identical seller who did not.
Why downsizers should check the net investment income tax separately
A retiree with modest ordinary income can still be pushed over the 3.8 percent NIIT threshold by the sale itself, because taxable gain is net investment income. The thresholds are $250,000 on a joint return and $200,000 otherwise, written into Section 1411(b) as fixed figures with no indexing. A sale that produces $120,000 of taxable gain on top of $180,000 of other income crosses the joint threshold and picks up 3.8 percent on the part above it.
The move itself may change the tax
Downsizing usually means moving, and sometimes across a state line. Some states tax the gain the federal exclusion just removed. If the sale and the move are in the same year, the order of the two matters, and it is worth checking the destination state before signing.

Methodology
- Exclusion caps, the 2-of-5 test, the nonqualified-use allocation, the reduced-exclusion fraction and the depreciation carve-out are taken from the text of 26 U.S.C. 121. The 3.8 percent rate and its thresholds are from 26 U.S.C. 1411. Both were read on 2026-07-30.
- Section 121 caps and Section 1411 thresholds are written in the statute as fixed dollar amounts with no indexing mechanism, so they are built in. Long-term capital gain brackets ARE indexed annually, so your rate is an input rather than a lookup.
- Figures were computed by two independently written engines that agree to the cent, and the calculator on this page reproduces both exactly.
- Federal only. State treatment varies and some states do not follow the federal exclusion.
