Whether your estate owes federal estate tax under the permanent $15M exclusion — and what the “2026 sunset” answer would have wrongly told you. Computes federal estate-tax exposure under the 2026 rules: a flat $15,000,000 basic exclusion per person, made PERMANENT by OBBBA §70106 — the long-scheduled TCJA sunset to ~$7M never happened, but AI trained before mid-2025 still tells you it did. Accounts for lifetime taxable gifts already made (they consume the unified exclusion) and a deceased spouse’s unused exclusion (DSUE) via portability. Shows the prior-law contrast so you can see exactly how much the “sunset” answer would have overstated your tax, and flags the separate state-level estate taxes (12 states + DC, thresholds from $1M) that the federal all-clear does not cover.
Input schema
| Property | Type | Required | Description |
|---|---|---|---|
| estateValue | number | no | Gross estate value ($) Everything you own at death — real estate, investments, retirement accounts, business interests, life-insurance proceeds you own. Use today’s value as an estimate. |
| maritalStatus | string | no | Marital / portability situation DSUE (deceased spousal unused exclusion) only counts if a Form 706 was filed for the deceased spouse to elect portability — it is not automatic. |
| dsueAmount | number | no | DSUE amount from deceased spouse ($) The unused exclusion ported from your deceased spouse (from their Form 706). Only applies with the “surviving spouse with elected DSUE” status above. |
| lifetimeGiftsUsed | number | no | Lifetime taxable gifts already made ($) Cumulative gifts above the annual exclusion ($19,000/recipient in 2026) reported on gift-tax returns. These consume your unified exclusion before death. |
| state | string | no | Does your state levy its own estate tax? WA, OR, MN, IL, MD, MA, RI, CT, VT, NY, ME, HI + DC levy their own estate tax with thresholds far below $15M (Oregon starts at $1M). This tool flags it but computes federal only. |
