What Happens to an S Corporation When the Owner Dies?

Estate planning for an S corporation involves more than deciding who will inherit the business.

The death of a shareholder can change how income is allocated, determine whether valuable tax losses survive, and create an opportunity to restructure the business with a substantially higher tax basis.

This is one of the most overlooked income tax issues in S corporation estate planning.

The Step-Up Applies to the Stock — Not the Corporate Assets

When an individual dies, inherited property generally receives a new tax basis equal to its fair market value as of the date of death, subject to exceptions and alternate valuation rules.

For an S corporation shareholder, the inherited property is the S corporation stock.

The assets inside the corporation do not automatically receive the same adjustment.

Consider an S corporation with:

• Corporate assets worth $3 million;
• A tax basis in those assets of $500,000; and
• S corporation stock worth $3 million.

After the shareholder’s death, the heirs could receive a $3 million basis in the S corporation stock. However, the corporation may still have only $500,000 of basis in its assets.

If the corporation later sells those assets for $3 million, it generally recognizes approximately $2.5 million of taxable gain. The fact that the heirs received a step-up in the stock does not eliminate the gain inside the corporation.

This distinction between outside stock basis and inside asset basis is one of the most important income tax issues in S corporation estate planning.

Who Reports the Income in the Year of Death?

An S corporation does not automatically close its books when a shareholder dies.

Under the default rule, the corporation’s income and deductions are generally allocated on a per-share, per-day basis.

That means the decedent’s final return and the estate or heirs divide the corporation’s annual income based on the number of days each owned the shares — not necessarily based on when the corporation actually earned the income.

This can produce an unfair result.

For example, assume a shareholder dies on September 30 and the corporation earns most of its annual profit during November and December. Under the default method, a portion of that later income can still be allocated to the decedent’s final income tax return.

The Closing-of-the-Books Election

The corporation may be able to elect to treat the year as two separate tax periods:

1. One period ending on the date the shareholder’s interest terminates; and
2. A second period beginning immediately afterward.

This is commonly called an interim closing-of-the-books election. Instead of using the default daily allocation, the corporation allocates actual income and deductions between the two periods.

The election generally requires the consent of the corporation and all affected shareholders.

The election can be valuable when:

• Income changed significantly around the date of death;
• The corporation completed a major sale after the shareholder died;
• The business is seasonal;
• The decedent and the heirs have different tax attributes; or
• One taxpayer has losses or deductions that can better absorb the income.

The election is not automatically better. The CPA should calculate the result under both methods before the return is filed.

Converting the Stock Basis Step-Up Into Asset Basis

For some families, the stock basis step-up creates an opportunity to restructure the business after the shareholder’s death.

One advanced strategy involves liquidating the S corporation and transferring the distributed assets into a partnership or limited liability company taxed as a partnership.

A corporate liquidation is generally treated as though the corporation sold its assets for fair market value. The resulting gain passes through to the S corporation shareholders.

That sounds expensive, but the inherited stock basis can change the overall result.

How the Strategy Works

Assume the heirs inherit S corporation stock with a fair market value and tax basis of $3 million. The corporation’s assets are also worth $3 million, but their tax basis is only $500,000.

If the corporation liquidates:

1. The corporation is treated as selling its assets for $3 million.
2. The corporation recognizes approximately $2.5 million of gain.
3. The gain passes through to the heirs.
4. The pass-through income increases the heirs’ basis in the S corporation stock.
5. The corporation distributes the assets to the heirs.
6. The liquidation is treated as payment in exchange for the heirs’ stock.
7. The heirs can receive the assets with a substantially higher basis and then contribute them to a partnership or LLC.

The gain passing through from the S corporation can be accompanied by a corresponding loss on the liquidation of the stock. In the right circumstances, the two results can largely offset.

The result is that the family moves from owning stock with a stepped-up basis to owning business assets with a stepped-up basis.

That higher asset basis can produce:

• Additional depreciation and amortization deductions;
• Less gain when assets are eventually sold;
• Greater flexibility to admit new owners;
• Partnership basis adjustments unavailable inside an S corporation; and
• More flexibility in allocating debt, income, and distributions.

This Strategy Requires Precise Timing

The liquidation, gain recognition, stock basis adjustment, and resulting shareholder loss must be coordinated carefully.

Completing the important steps during the same tax year helps prevent the family from recognizing taxable gain in one year and receiving a potentially limited capital loss in a later year.

Character also matters. Depreciation recapture and other ordinary income do not always match the character of the loss recognized on the stock.

The analysis must account for:

• Ordinary income versus capital gain;
• Depreciation and amortization recapture;
• State income taxes;
• Corporate liabilities;
• Built-in gains tax exposure;
• Installment obligations;
• Accounts receivable and other ordinary-income assets;
• Real estate transfer taxes and recording costs;
• Contracts, licenses, payroll accounts, and legal ownership; and
• Whether minority shareholders are involved.

The CPA, estate attorney, corporate attorney, appraiser, and business owners need to coordinate before the liquidation documents are signed.

Suspended Losses Can Disappear at Death

S corporation shareholders often have losses that were generated economically but never deducted because of tax limitations.

The three main limitations are:

• The shareholder’s stock and debt basis;
• The shareholder’s amount at risk; and
• The passive activity loss rules.

Each limitation operates differently, and the order in which they apply matters.

Passive Activity Losses

Passive losses receive special treatment when an ownership interest passes at death.

The decedent’s suspended passive losses are deductible only to the extent they exceed the basis increase received by the heirs. The portion of the losses equal to the step-up in basis disappears permanently.

For example:

• Suspended passive losses: $500,000;
• Basis increase at death: $400,000; and
• Remaining deductible suspended passive loss: $100,000.

The other $400,000 is lost because the heirs received a corresponding basis increase. This can create an uncomfortable result: the step-up eliminates future gain, but it can also eliminate suspended deductions.

Basis-Limited and At-Risk Losses

Losses suspended because the shareholder lacked basis or sufficient amount at risk also require review before death.

These tax attributes generally do not transfer to the heirs in the same manner as the stock itself.

A family should not assume that losses shown on a prior-year tax workpaper will remain available after the shareholder dies.

The CPA should maintain a detailed schedule separating:

• Stock basis limitations;
• Debt basis limitations;
• At-risk limitations;
• Passive activity limitations; and
• Losses associated with each separate activity.

Without those schedules, it can be extremely difficult to determine what remains deductible on the final return.

Should the Owner Sell the Business Before Death?

A sale before death can release suspended passive losses when the owner disposes of the entire activity in a fully taxable transaction to an unrelated buyer.

However, that does not make a deathbed sale automatically beneficial.

Selling before death can:

• Trigger gain that would otherwise be eliminated through a basis step-up;
• Accelerate depreciation recapture;
• Create current federal and state income tax;
• Release suspended losses that would otherwise disappear;
• Convert an illiquid business into cash or a note; and
• Simplify administration for the family.

The correct decision requires comparing two complete scenarios.

Scenario One: Sell Before Death

The analysis should calculate:

• Gain on the stock or assets;
• Available passive losses;
• Basis-limited and at-risk losses;
• Depreciation recapture;
• Net investment income tax;
• State income tax;
• Installment-sale treatment; and
• The after-tax value received by the family.

Scenario Two: Hold Until Death

The analysis should calculate:

• The expected basis adjustment;
• The value of suspended losses that will disappear;
• The tax consequences of a post-death liquidation;
• The ability to restructure as a partnership;
• Future depreciation and amortization; and
• The heirs’ plans for operating or selling the business.

Sometimes the value of unlocking suspended losses exceeds the benefit of waiting for a step-up. In other cases, selling before death creates a large tax bill that proper post-death planning could have avoided.

Estate Planning Must Include the Income Tax Plan

A traditional estate plan often focuses on wills, trusts, probate, estate taxes, and who will control the company.

Those items are important, but they are not enough.

An effective S corporation succession plan should also address:

• The projected value and tax basis of the stock;
• The tax basis of each major corporate asset;
• Shareholder stock and debt basis;
• Suspended losses;
• Built-in gains exposure;
• Buy-sell agreements;
• Life insurance funding;
• Voting and nonvoting ownership;
• S corporation shareholder eligibility;
• The allocation of income in the year of death;
• Whether the corporation should continue, sell its assets, or liquidate; and
• Whether a partnership structure would better serve the next generation.

The tax plan should be modeled before the shareholder’s health declines. Waiting until after death eliminates planning opportunities and forces the family to make major decisions while handling the personal and legal consequences of losing a family member.

The Bottom Line

An inherited S corporation presents both a tax problem and a planning opportunity.

The heirs generally receive a new basis in the S corporation stock, but the corporation’s assets retain their existing basis. Suspended losses can disappear. Income in the year of death can be allocated in unexpected ways.

At the same time, a carefully coordinated liquidation and restructuring can sometimes convert the stock basis adjustment into a more valuable asset basis adjustment.

These results do not happen automatically. They require accurate basis records, a defensible business valuation, timely elections, and coordination between the family’s CPA and estate attorney.

What happens to the business’s income, assets, basis, and suspended losses when the shareholder dies? The answer can change the family’s tax burden by hundreds of thousands — or even millions — of dollars.
