Ohio does not impose a state estate tax. The state repealed its estate tax effective January 1, 2013.

Previously, Ohio imposed an estate tax on estates exceeding $338,333 — one of the lowest thresholds in the nation. The repeal significantly simplified estate planning for Ohio residents.

Ohio's manufacturing base, agricultural sector, and urban real estate markets create diverse estate planning needs. The state's central location and relatively low cost of living make it competitive for retaining high-net-worth families.

Ohio residents face only the federal estate tax. The **$15 million exemption with portability and 40%** top rate applies.

No state estate tax filing is required.

Ohio borders Pennsylvania (which has an inheritance tax), Michigan, Indiana, Kentucky (which has an inheritance tax), and West Virginia. Those with multi-state assets should evaluate the transfer tax implications in each state where property is located.

Ohio is a common-law property state. The surviving spouse's elective share under Ohio Rev.

Code 2106.01 provides either one-third or one-half of the net estate depending on the number of descendants. Ohio's transfer-on-death (TOD) designation for real property (ORC 5302.22) allows real estate to pass outside probate, simplifying administration.

Closely held business interests — including manufacturing operations, automotive suppliers, and family farms — are common Ohio estate assets. Business valuation requires consideration of lack-of-marketability and minority interest discounts.

Buy-sell agreements funded by life insurance help ensure liquidity for estate tax payments and smooth business transitions.

Because Ohio does not impose a state estate tax, the federal estate tax is the only transfer tax layer. The current federal exemption of $15 million per individual (2025) shelters the vast majority of estates.

However, estates that exceed this threshold face a top marginal rate of 40%, making federal planning essential for high-net-worth Ohio residents.

The Tax Cuts and Jobs Act (TCJA) doubled the federal exemption effective 2018, but this increase is scheduled to sunset after 2025. If Congress does not act, the exemption will revert to approximately $7 million (adjusted for inflation).

For Ohio residents with estates between $7 million and $15 million, this sunset creates a planning window: transfers made now under the higher exemption will not be clawed back, even if the exemption later decreases.

The absence of a state estate tax in Ohio simplifies the analysis — there is no gap between state and federal exemptions to navigate, no separate state return to file, and no risk of double taxation. However, this also means there is no state-level deduction to offset federal liability.

Federal planning tools — marital deductions, charitable deductions, and the unified credit — carry the full weight of estate tax mitigation. Use the Ohio estate tax calculator to model current and post-sunset scenarios, and review the Ohio probate cost calculator to understand full settlement costs.

Federal portability allows a surviving spouse to inherit the deceased spouse's unused estate tax exclusion (DSUE), effectively doubling the available federal exemption to $30 million for married couples. Electing portability requires filing Form 706 for the first-to-die spouse, even if no federal estate tax is owed — a step that is frequently overlooked when no tax appears to be due.

Because Ohio does not impose a state estate tax, there is no state-level portability concern. The federal election is the only one that matters, and it applies automatically to the surviving spouse's estate once made.

This is simpler than in estate-tax states, where the lack of state portability forces the use of bypass trusts to preserve both exemptions.

Despite this simplicity, portability has limitations. The DSUE amount is not indexed for inflation — it locks in at the value of the first spouse's unused exemption at the date of death.

If the surviving spouse remarries and the new spouse dies, the DSUE from the first spouse is lost. For Ohio families with significant wealth, bypass trusts may still be preferable to portability because they provide asset protection, generation-skipping benefits, and inflation-adjusted growth outside the surviving spouse's taxable estate.

Without a state estate tax, Ohio residents focus planning efforts on the federal layer. The current $15 million exemption provides substantial shelter, but the scheduled TCJA sunset makes it prudent to accelerate planning.

Irrevocable trusts — including ILITs, SLATs, and QPRTs — remove assets from the taxable estate permanently. Once transferred, these assets and their future appreciation are outside the federal estate, regardless of future exemption changes.

Annual exclusion gifts of $19,000 per recipient (2025) remain the simplest estate reduction tool. Married couples can jointly gift $38,000 per recipient through gift-splitting.

Over a decade, a family gifting to four beneficiaries annually removes $1.44 million from the estate with no gift tax return required. Charitable deductions — whether through outright bequests, donor-advised funds, or charitable trusts — further reduce the taxable estate while supporting philanthropic goals.

GRATs and GRUTs (grantor retained unitrusts) transfer appreciation to beneficiaries at minimal transfer tax cost. For Ohio residents holding concentrated stock positions or rapidly appreciating assets, these vehicles are particularly efficient.

Family limited partnerships and LLCs may provide valuation discounts for gift and estate tax purposes, though the IRS scrutinizes these structures closely. Professional valuation and proper documentation are essential.
