Section 303 Stock Redemption: Using Corporate Funds to Pay Estate Taxes Without Dividend Treatment

Section 303 of the Internal Revenue Code is one of those provisions that exists for a very specific problem and solves it almost perfectly — which is why it's been sitting largely unchanged in the code for decades. If you own a closely-held corporation and your estate will owe federal estate tax, Section 303 lets the corporation redeem enough of your stock to pay that estate tax bill, and does so without the redemption being treated as a dividend.

That's the 30-second version. The rest of this deep dive covers why it matters, how it works mechanically, the qualification tests, the planning moves that preserve qualification, and the ways it coordinates with other estate tax planning tools.

When a business owner dies with a significant estate, the estate typically owes federal estate tax nine months after death (the IRS is flexible on the extension of time to pay in some circumstances — see below on Section 6166). The estate has to pay in cash.

The problem: most closely-held business owners don't have enough cash. Their net worth is concentrated in the business. The business itself may have cash, but getting that cash from the corporation into the estate's hands is expensive.

If the corporation simply distributes cash as a dividend, the distribution is taxed as ordinary income (or, at best, qualified dividend income) to the shareholder or the estate. That's a tax on top of the estate tax — money flowing out of the corporation loses 15-23.8% to federal income tax (plus state) before it's available to pay the estate tax.

If the corporation redeems stock from the estate, the redemption is generally treated as a sale under Section 302 — except when it's not. The default rule under Section 302 is that if the shareholder's ownership percentage doesn't meaningfully decrease after the redemption, the distribution is treated as a dividend (not a sale). For a closely-held business where the estate is the sole shareholder or holds nearly all shares, any pro-rata-ish redemption looks like a dividend.

Section 303 cuts through that. For estates that qualify, a redemption up to the amount needed to pay death taxes and administration expenses is automatically treated as a sale — with a basis step-up to date-of-death value (more on this in 7.4) — rather than as a dividend. The estate essentially gets that cash tax-free.

Here's the sequence:

1. Owner dies holding stock in closely-held corporation.
2. Estate is subject to federal estate tax.
3. Estate's stock receives a stepped-up basis to the date-of-death fair market value.
4. Corporation redeems (repurchases) a portion of the estate's stock.
5. Cash flows from corporation to estate.
6. Redemption is treated as a sale under Section 303 — with the stock's basis equal to date-of-death value, the gain is typically near zero.
7. Estate uses the cash to pay federal estate taxes, state estate/inheritance taxes, and administration expenses.

The beauty of this structure is the combination: the stepped-up basis at death minimizes or eliminates capital gain on the redemption, and Section 303 ensures the redemption isn't recharacterized as a dividend despite the fact that the ownership percentages of remaining shareholders don't meaningfully change.

To use Section 303, the closely-held corporation stock must exceed 35% of the adjusted gross estate. This is the core qualification test.

The 35% calculation:

• Adjusted gross estate = gross estate minus deductible expenses and losses (Sections 2053 and 2054).
• Value of the qualifying stock must exceed 35% of this figure.
• If multiple corporations are involved, stock in each 20%+ owned corporation can be aggregated.

The 35% threshold is binary. At 34.9%, Section 303 doesn't apply. At 35.1%, it does. This means planning matters. If you're close to the threshold, the value of the stock and the composition of your estate should be monitored regularly. Post-death valuations can be subject to IRS challenge, and the estate can elect to use the alternate valuation date (6 months after death) if values dropped.

The threshold also means that heavily diversified estates — where the business is valuable but less than a third of total wealth — don't qualify. This catches some founders who have sold substantial stock, diversified into marketable securities, or accumulated significant real estate outside the business.

Section 303 doesn't let you redeem unlimited amounts. The permissible redemption is capped at the sum of:

• Federal and state estate taxes (including interest, generation-skipping transfer tax)
• Funeral expenses deductible under Section 2053
• Administration expenses deductible under Section 2053

So if the combined federal + state estate tax liability is $4 million and deductible administration expenses add $500,000, up to $4.5 million of stock can be redeemed under Section 303 without dividend treatment.

If the corporation redeems more than this cap, the excess is analyzed under normal Section 302 rules. That's not necessarily a bad outcome — it just means you don't get the Section 303 safe harbor on the excess.

Section 303 redemptions must occur within specific time windows:

• Within 3 years and 90 days after the filing of the estate tax return, OR
• Within 60 days after a Tax Court decision on any estate tax deficiency becomes final, OR
• If Section 6166 (discussed below) applies, during the period in which installments of estate tax are being paid under that section.

The timing flexibility matters. If the estate is in litigation over valuation or a deficiency, the redemption window is effectively extended. If Section 6166 is being used to spread the estate tax over up to 14 years, Section 303 redemptions can happen throughout that period.

The 35% threshold is where most of the planning attention goes. Several moves can help preserve or achieve qualification:

Aggregate multiple corporations. If you own 20%+ of multiple corporations, the stock in each can be aggregated to meet the 35% test.

Avoid pre-death diversification that drops the business below 35%. Counterintuitively, there's a trade-off between diversifying your personal wealth (generally good for risk management) and maintaining Section 303 qualification (good for estate tax liquidity). This is one of the planning conversations that should happen with an estate attorney.

Consider the attribution rules. Stock owned by family members may be attributed to the decedent for some purposes. Understanding which attributions apply can affect both qualification and the effective scope of the redemption.

Watch the alternate valuation election. If the business value drops between death and 6 months later, electing alternate valuation can both lower the overall estate tax and potentially affect 35% qualification. Usually the choice is made for the tax reduction, but the knock-on effects on Section 303 should be considered.

Section 303 is rarely used alone. It's typically paired with Section 6166, which lets estates pay estate tax attributable to a closely-held business in installments over up to 14 years with a favorable interest rate on the first tranche.

The combination is powerful. Section 6166 spreads the estate tax burden over time so the business can fund it from ongoing cash flow rather than a single liquidation event. Section 303 then allows corporate redemptions to fund the annual installment payments without dividend treatment.

Together, these provisions can transform an otherwise impossible estate tax situation — "how do I pay $5 million in cash tax on a business I can't easily sell?" — into a manageable 10-15 year payout funded by normal business operations.

Section 6166 has its own qualification rules (the business must exceed 35% of the adjusted gross estate, with specific definitions that differ slightly from Section 303's test) and acceleration triggers (sales or withdrawals of 50%+ of the business interest can accelerate all remaining payments). Anyone planning to use Section 303 should understand 6166 in parallel.

Even with Section 303's tax treatment solved, the corporation still needs cash to fund the redemption. The common funding sources:

Corporate-owned life insurance on the decedent. The cleanest funding mechanism. The corporation owns a policy on the owner's life, pays the premiums, and receives the death benefit tax-free (with potential exception for the alternative minimum tax on C corporations — though the corporate AMT has been modified significantly in recent legislation). At death, the corporation has cash, which it uses to redeem the estate's stock.

Corporate accumulated cash and working capital. Less efficient — cash tied up in the business is cash not being invested in the business. Works if the business is cash-rich.

Corporate borrowing. The corporation borrows against its balance sheet and uses loan proceeds to fund the redemption. Works if the business can service additional debt.

Installment redemptions. The corporation redeems stock over time, funded by ongoing operations. Works particularly well when combined with Section 6166's installment payment of estate tax.

Section 303 applies to stock in a corporation, without specifying C or S. The mechanics work for both, but the context matters.

For S corporation owners, pass-through taxation means different planning considerations apply — S corp distributions are not dividends in the first place, and the accumulated adjustments account affects how distributions are treated. The Section 303 safe harbor still matters for S corporations, but the analysis of "would this otherwise be treated as a dividend?" is different.

For C corporation owners, the Section 303 safe harbor is more clearly valuable because dividend treatment is the default alternative.

The qualification decision matters long before death. Several pre-death moves affect qualification:

• Lifetime gifting of business interests to family members (which can reduce the 35% threshold qualification — but also reduces the taxable estate).
• Diversification of personal wealth (same trade-off).
• Whether to hold non-operating assets inside or outside the corporation.
• Whether to buy corporate life insurance for Section 303 funding purposes.
• Structure of buy-sell agreements — a mandatory buy-sell that requires redemption at death changes the analysis compared to a discretionary redemption.

All of these should be live decisions for owners of closely-held corporations with estates likely to exceed the federal estate tax exemption. The exemption has been volatile legislatively and is scheduled to be cut roughly in half after 2025 under current law, potentially bringing more estates into the taxable range.

If you own a closely-held corporation and your estate is approaching or above the federal estate tax exemption — or likely to be after a potential reduction — Section 303 planning belongs in your estate plan. It's one of the few provisions that genuinely solves the liquidity problem that kills many closely-held business transitions.
