Inheriting a family business triggers a set of tax decisions that are both high-stakes and time-sensitive. The business assets -- equipment, real estate, goodwill, inventory -- all receive a step-up in basis to fair market value at the date of death under IRC Section 1014. But unlike inheriting a brokerage account, a business comes with ongoing obligations: payroll, entity tax elections, creditor claims, and valuation requirements the IRS scrutinizes closely. The decisions you make (or fail to make) in the first nine to twelve months can lock in or destroy hundreds of thousands of dollars in tax savings.
Several critical deadlines start running immediately upon death. Payroll tax deposits must continue without interruption. The business valuation must be ordered within 60-90 days. The Form 706 estate tax return is due in 9 months, and missing that deadline forecloses the Section 6166 installment payment election and the Section 2032A special use valuation -- both of which can save hundreds of thousands of dollars.
When you inherit a business, the step-up does not apply to the business as a single lump. Each underlying asset gets its own basis reset to fair market value on the date of death. That means equipment, vehicles, real estate, inventory, accounts receivable, customer lists, and goodwill are each valued and stepped up independently. Technical detail
This matters because each asset class has different tax treatment going forward. Equipment and vehicles can be depreciated under their applicable recovery periods. Real estate follows its own depreciation schedule. Goodwill and other Section 197 intangibles are amortized over 15 years. If the previous owner had fully depreciated a piece of equipment that is still worth $80,000 at death, your new depreciable basis is $80,000 -- not zero. That is new depreciation deductions the prior owner had already exhausted.
The catch: you need an asset-by-asset valuation to claim any of this. If you inherit a business and never document what each asset was worth on the date of death, the IRS can default to the prior owner's basis. For a business that has been running for 20 or 30 years, that could mean a basis of near zero on assets worth hundreds of thousands of dollars. Getting the valuation done early is not optional -- it is the foundation every other tax decision rests on.
Valuation: The IRS Knows What to Look For
The IRS scrutinizes estate valuations of closely held businesses more than almost any other asset class. There is no public market price to reference, so the valuation depends entirely on the appraiser's methodology. Technical detail
The IRS's own framework for these valuations comes from Revenue Ruling 59-60, which has been in effect since 1959 and remains the governing authority. It requires the appraiser to consider eight specific factors:
- The nature and history of the business
- The general economic outlook and the condition of the specific industry
- The book value and financial condition
- The earning capacity
- The dividend-paying capacity
- Whether goodwill or other intangible value exists
- Prior sales of the stock and the size of the block being valued
- The market price of comparable publicly traded companies
Revenue Ruling 59-60 explicitly rejects formulaic approaches. The IRS does not accept "three times earnings" or "five times EBITDA" as standalone methods. The appraiser must analyze all eight factors and explain how they weighted each one.
Discounts the IRS Will Challenge
Most inherited business interests qualify for two valuation discounts that can substantially reduce the estate tax value: a discount for lack of marketability (you cannot sell a private business interest on an exchange) and a discount for lack of control (if the heir inherits less than a controlling interest). Combined, these discounts can reduce the reported value by 25% to 40%.
The IRS challenges these discounts regularly. If the discount is too aggressive or poorly supported, the IRS will propose a higher valuation and a correspondingly higher estate tax bill. The solution is a qualified business appraiser -- not the family accountant, not a real estate agent -- who produces a report that addresses all eight Revenue Ruling 59-60 factors and documents every discount with market data.
Timing
Order the business valuation within 60 to 90 days of death. The appraiser needs access to financial records, tax returns, contracts, and key employees. The longer you wait, the harder it becomes to reconstruct the business's condition as of the exact date of death.
The decedent's business was organized as some type of entity -- sole proprietorship, partnership, LLC, S corporation, or C corporation. The entity type directly controls how the business income is taxed going forward, and the right structure for the original owner may be the wrong structure for you.
Sole proprietorship. If the owner ran the business as a sole proprietor, the business dies with them in a legal sense. You inherit the assets, not the entity. You will need to decide whether to continue as a sole proprietor, form an LLC, or elect S corporation status. Each has different liability, self-employment tax, and administrative implications.
S corporation. S corporation status can be involuntarily terminated if the new ownership structure violates S corp eligibility rules. If the business interest passes to a trust, the trust must be an eligible S corporation shareholder (a grantor trust, a qualified subchapter S trust, or an electing small business trust). Technical detail
Partnership or LLC. Check the operating agreement. Many operating agreements contain buy-sell provisions, rights of first refusal, or mandatory buyout clauses that trigger upon the death of a member. These provisions may override what you expected to inherit and can dictate both the timeline and the price.
C corporation. Inheriting C corporation stock gets the standard step-up on the stock basis. But the assets inside the C corporation do not get a step-up -- the corporation is a separate taxpayer, and its inside basis remains unchanged. Technical detail
A CPA or tax attorney should evaluate the entity structure within the first 60 days. The wrong structure can cost more in ongoing taxes than any single transaction.
- IRS defaults to the prior owner's basis (near zero on most assets)
- No stepped-up basis to claim on equipment, real estate, or goodwill
- Selling the business later triggers $2 million in taxable gain
- No new depreciation deductions while operating
- Equipment basis resets to $500,000 (new depreciation deductions)
- Real estate, goodwill, and intangibles each receive independent step-up
- Selling for $2.1 million triggers only $100,000 in gain
- Fresh depreciation generates years of tax shield while operating
This is the central question most heirs face, and the tax consequences differ dramatically depending on the path.
Keep the business
If you continue operating the business, your primary tax advantage is the stepped-up basis in all the business assets. You get fresh depreciation and amortization deductions on equipment, real estate, and intangibles valued at their date-of-death fair market value. For a capital-intensive business with old, fully depreciated equipment, this can generate significant tax shield for years.
The ongoing tax obligations continue as before: income tax on business profits, self-employment tax (if a pass-through entity), payroll taxes on employees, state and local taxes. Nothing changes about the operational tax burden except the new depreciation deductions.
Sell the business
If you sell soon after inheriting, the stepped-up basis means your taxable gain is measured from the date-of-death value, not the original owner's cost. A business worth $2 million at death, sold for $2.1 million three months later, generates only $100,000 of gain -- not the $1.5 million gain that would have existed under the original basis.
The sale of a business is not a single transaction for tax purposes. It is an allocation of the purchase price across every asset category under IRC Section 1060, reported on Form 8594. The allocation determines whether the gain is ordinary income (inventory, accounts receivable), Section 1231 gain (equipment, real estate), or capital gain (goodwill). The buyer and seller must use consistent allocations. How the purchase price gets allocated between these categories significantly affects the total tax bill.
Wind down the business
Winding down involves liquidating assets, collecting receivables, paying creditors, and distributing what remains. Each asset sale is a taxable event measured against the stepped-up basis. If you wind down quickly after the step-up, most asset sales will generate minimal gain. But if the wind-down drags on for years and asset values change, gains or losses will accumulate.
Winding down also triggers final payroll tax returns, state business dissolution filings, and potential cancellation-of-debt income if any business debts are forgiven. A CPA should map out the full sequence before you start liquidating.
Employment Tax Obligations You Inherit
If the business has employees, you inherit the employer's tax obligations immediately. This includes:
- Payroll tax deposits. Federal income tax withholding, Social Security, and Medicare taxes must continue to be deposited on the existing schedule. Missing even one deposit triggers penalties and interest.
- FUTA. Federal Unemployment Tax continues at 6% on the first $7,000 of wages per employee, offset by state unemployment tax credits.
- State employment taxes. Workers' compensation, state unemployment, and state income tax withholding vary by state but do not pause because the owner died.
- Successor employer rules. If the business continues under your ownership, you may be treated as a successor employer for purposes of the Social Security wage base and FUTA wage base. Whether you qualify as a successor employer affects how much you owe in payroll taxes for the remainder of the year.
Technical detail
Under Rev. Rul. 62-60, a successor employer who acquires substantially all the property used in a trade or business may include wages paid by the predecessor in calculating whether employees have hit the annual wage base limits. This prevents double-counting of the wage base in the year of transfer.
The critical action: do not let payroll lapse. If the business has employees, someone needs to continue running payroll from day one. Unpaid payroll taxes are one of the few debts that can pierce through to personal liability.

Section 6166: Spreading Estate Tax Over 14 Years
If the closely held business interest exceeds 35% of the adjusted gross estate and the estate actually owes federal estate tax, the executor can elect under IRC Section 6166 to pay the estate tax attributable to the business in installments over up to 14 years. Technical detail
This election is only available if the Form 706 is filed on time. A late-filed return disqualifies the election entirely, which is one reason the Form 706 deadline is non-negotiable for estates with significant business interests.
Section 2032A: Special Use Valuation for Business Real Property
If the business owns real property used in the business or in farming, the executor may be able to elect special use valuation under IRC Section 2032A. This allows the real property to be valued at its current business use value rather than its highest-and-best-use fair market value. For a family farm on the edge of a growing suburb, the difference between agricultural-use value and development value can be millions of dollars.
The maximum reduction for estates of decedents dying in 2026 is $1,460,000. Rev. Proc. 2025-32 sets the inflation-adjusted Section 2032A limit at $1,460,000 for 2026. The requirements are strict:
- The real and personal property used in the business must constitute at least 50% of the adjusted gross estate value
- The qualified real property alone must constitute at least 25% of the adjusted gross estate value
- The decedent or a family member must have materially participated in the business for 5 of the 8 years preceding death
- The property must pass to a qualified heir
- The qualified heir must continue to use the property in the business for 10 years after death, or the tax savings are recaptured
This election is also made on Form 706 and must be filed on time.
Inheriting a business means inheriting its liabilities -- known and unknown. Several insurance and liability issues require immediate attention:
Existing insurance policies. Business insurance policies (general liability, professional liability, property, workers' compensation) typically require notification when ownership changes. Some policies terminate upon the death of the named insured. If coverage lapses even briefly, you are personally exposed to any claims that arise during the gap.
Key person insurance. If the decedent had a key person life insurance policy naming the business as beneficiary, those proceeds are generally income-tax-free to the business under IRC Section 101(a). But the proceeds are included in the decedent's gross estate for estate tax purposes if the decedent held incidents of ownership in the policy. Coordinate with the estate attorney on how these proceeds factor into the overall estate valuation.
Pending claims and unknown liabilities. Environmental liabilities, product liability claims, and pending litigation transfer to the new owner. Before deciding to keep or sell, conduct due diligence on the business's liability exposure -- the same diligence you would perform if you were buying the business from a stranger.
Buy-sell agreements funded by life insurance. Many family businesses have buy-sell agreements funded by life insurance policies. If the agreement calls for the remaining owners to buy out the deceased owner's interest, the insurance proceeds fund that purchase. The tax treatment depends on whether the agreement is structured as a cross-purchase or entity redemption. Technical detail
Common Mistakes
Not getting an independent valuation. Using the family bookkeeper's estimate or a back-of-envelope calculation invites an IRS challenge. The IRS has a dedicated team of engineers and appraisers who review business valuations on estate tax returns. An independent, qualified appraiser who follows Revenue Ruling 59-60 is not optional -- it is your primary defense in an audit.
Assuming the entity structure should stay the same. The original owner may have chosen the entity type decades ago under different tax law and different personal circumstances. What worked for a 60-year-old founder running the business day-to-day may not work for a 35-year-old heir who plans to hire a manager. Review the entity structure within 60 days.
Missing step-up documentation for individual assets. The step-up applies asset-by-asset, but you have to prove it. If you inherit the business and start operating without documenting the fair market value of each asset on the date of death, you have no evidence to support the stepped-up basis when you eventually sell or when the IRS asks.
Ignoring the Form 706 deadline. Even if you believe no estate tax is owed, a timely Form 706 preserves the Section 6166 installment payment option, the Section 2032A special use valuation election, and the portability of the deceased spouse's unused exemption. Missing this deadline can foreclose options worth hundreds of thousands of dollars.
Treating the business as a going concern without assessing the wind-down option. Emotional attachment to the family business is understandable. But the tax math sometimes favors a quick sale or wind-down while the stepped-up basis is still close to market value. Running the business at a loss for years out of sentimentality is not a tax strategy.
Overlooking state-level estate taxes. Twelve states and the District of Columbia impose their own estate taxes, many with exemptions far below the federal $15 million. A closely held business that owes no federal estate tax could still owe significant state estate tax in states like Oregon (with a $1 million exemption) or Massachusetts ($2 million exemption).
If the decedent ran a C corporation, the assets inside the corporation do not receive a step-up in basis -- only your stock basis steps up. This creates a potential double-tax problem on any future asset sale. Evaluating conversion to S corporation status or a structured liquidation should be one of the first conversations with your CPA, ideally within 60 days of inheriting.
An inherited business is one of the few situations where you need a CPA, a business valuation appraiser, and likely an estate attorney -- all working together within the first 90 days. The CPA handles entity structure analysis, step-up documentation, tax return deadlines, and the keep-vs-sell tax modeling. The appraiser produces the valuation that supports every number on Form 706. The attorney handles probate, operating agreement interpretation, and creditor claims.
If the business has annual revenue above $500,000, has employees, or owns real estate, the cost of this professional team (typically $15,000 to $50,000 for the first year) is small relative to the tax savings and liability protection at stake. The cost of a CPA for this type of engagement is higher than standard tax preparation, but the decisions being made are not standard.
