A Domestic International Sales Corporation, known in its current form as an IC-DISC (Interest Charge Domestic International Sales Corporation), is a separate U.S. corporation that American exporters use to convert a portion of their export profits from ordinary income into qualified dividend income. The exporter pays the IC-DISC a commission on export sales and deducts that commission at ordinary income tax rates. The IC-DISC owes no federal income tax on the commission it receives. When the money is distributed to shareholders as a dividend, it is taxed at long-term capital gains rates. Congress created the original DISC in the Revenue Act of 1971 and later replaced it with the IC-DISC, which remains one of the few export incentives still available to U.S. businesses regardless of size.1Office of the Law Revision Counsel. 26 USC 991 – Taxation of a Domestic International Sales Corporation
How the Tax Savings Actually Work
The IC-DISC is owned by the same shareholders as the exporting company but operates as its own domestic C corporation. The exporter pays it a commission tied to qualified export sales. That commission is deductible for the exporter at ordinary rates. The IC-DISC pays no federal income tax on what it receives.2eCFR. 26 CFR 1.991-1 – Taxation of a Domestic International Sales Corporation
When the IC-DISC distributes that money, individual shareholders treat it as a qualified dividend. Qualified dividends are taxed at the long-term capital gains rate of up to 20%, plus the 3.8% net investment income tax if it applies, for a combined ceiling of 23.8%. The difference between the ordinary rate the exporter avoided through the deduction and the lower rate the shareholder pays on the dividend is a permanent tax savings on every dollar routed through the structure.
The math is sharpest for owners of pass-through businesses. A commission paid by a pass-through reduces income that would otherwise flow to shareholders at rates as high as 37%. Coming back as a qualified dividend, that same income is taxed at 23.8% or less. The spread produces savings roughly in the range of 10% to 13% of the commission amount. For C corporation exporters, the arithmetic is less compelling: the deduction saves tax at the 21% corporate rate, which is already below the 23.8% dividend rate. The structure works best when the entity paying the commission is taxed as a pass-through.
Who Can Use One
Manufacturers, distributors, software developers, architecture and engineering firms, and service providers whose revenue is tied to goods or services used outside the United States can all potentially qualify. Size does not matter. A small machine shop exporting $500,000 in parts a year can set one up as readily as a manufacturer with tens of millions in export sales. What matters is whether the products meet the definition of qualified export property and whether the export volume justifies the setup and compliance work.
Some entities are barred from electing IC-DISC status altogether: tax-exempt organizations, personal holding companies, banks and other financial institutions, insurance companies, regulated investment companies, and S corporations.3Office of the Law Revision Counsel. 26 US Code 992 – Requirements of a Domestic International Sales Corporation The IC-DISC itself must be a standalone C corporation. It usually has no employees and no operations beyond receiving commissions, holding qualified assets, and paying dividends.
What Counts as Export Property
Not everything shipped overseas qualifies. To count as export property, goods must be manufactured, produced, grown, or extracted in the United States, either by the exporter or by another party under contract with the exporter. The regulations recognize several ways to meet the manufacturing threshold: substantially transforming raw materials into a different product, performing operations generally considered manufacturing in the relevant industry, or passing a 20% value-added test in which the exporter’s conversion costs (direct labor and factory overhead) account for at least 20% of cost of goods sold or adjusted basis.4eCFR. 26 CFR 1.993-3 – Definition of Export Property
The property also has to pass a foreign-content limit: no more than 50% of its fair market value can come from articles imported into the United States.5Internal Revenue Service. Instructions for Form 1120-IC-DISC And it has to meet a destination test, meaning the goods must ultimately be delivered for use or consumption outside the United States. The typical case involves handing goods to a carrier or freight forwarder within the U.S. for shipment abroad, but the rules also cover situations where a buyer takes delivery domestically and exports within one year.
Qualified Export Receipts
At least 95% of the IC-DISC’s total gross receipts for the year must be qualified export receipts, and at least 95% of its assets at year-end (measured by adjusted basis) must be qualified export assets.6eCFR. 26 CFR 1.993-2 – Definition of Qualified Export Assets Qualified export receipts include sales and leases of export property, services related and subsidiary to a qualified sale or lease, engineering and architectural services on construction projects located outside the United States, and interest and dividends from qualified export assets.7Office of the Law Revision Counsel. 26 USC 993 – Definitions and Special Rules
The engineering and architectural category is easy to overlook. Firms that don’t ship physical products sometimes assume the IC-DISC is not for them, but design and engineering work on foreign construction projects has its own qualifying slot.
How Much Income the IC-DISC Can Earn
The commission or transfer price between the exporter and the IC-DISC determines how much income actually shifts into the tax-advantaged structure. Section 994 offers three methods, and the exporter can use whichever produces the largest allowable income for the IC-DISC:8Office of the Law Revision Counsel. 26 USC 994 – Inter-Company Pricing Rules
- The 4% gross receipts method assigns the IC-DISC taxable income equal to 4% of qualified export receipts on the transaction, plus 10% of the IC-DISC’s export promotion expenses tied to those receipts.
- The 50/50 combined taxable income method gives the IC-DISC half of the combined taxable income the exporter and IC-DISC derive from the export transaction, plus 10% of export promotion expenses.
- The Section 482 method uses the actual sales price charged, subject to the arm’s-length transfer pricing rules of Section 482.
For most small and mid-sized exporters, the 4% method is simpler and often more favorable, especially when export margins are thin. The 50/50 method tends to produce a larger commission when export margins are high. Nothing requires the same method every year or across every product line, which leaves room to optimize annually.
The $10 Million Cap and the Interest Charge
Two features cap the benefit. First, only the taxable income of the IC-DISC attributable to the first $10 million in qualified export receipts is eligible for deferral. Anything above that is automatically deemed distributed to shareholders and taxed in the year earned under Section 995(b)(1)(E).9Office of the Law Revision Counsel. 26 USC 995 – Taxation of DISC Income to Shareholders A controlled group with more than one IC-DISC shares a single $10 million ceiling.5Internal Revenue Service. Instructions for Form 1120-IC-DISC Certain other categories trigger deemed distributions regardless of the cap, including interest earned on producer’s loans, gains on non-export assets previously transferred to the IC-DISC, and 50% of taxable income from military property. If the election is revoked or the corporation fails its qualification tests, all accumulated deferred income becomes taxable to shareholders.
Second, deferral is not free. The “Interest Charge” in the name is exactly what it sounds like: shareholders pay an annual interest charge on the federal tax they would have owed if the deferred IC-DISC income had been included on their returns. The charge is calculated by multiplying the shareholder’s DISC-related deferred tax liability by a base period T-bill rate factor the IRS publishes each year. For the 2025 tax year that factor was 0.041641381 for a 365-day year.10Internal Revenue Service. Form 8404 – Computation of Interest Charge on DISC-Related Deferred Tax Liability Shareholders report and pay the charge on IRS Form 8404, due by the filing deadline of their own income tax return (not counting extensions). Corporate shareholders other than S corporations can deduct the charge as interest expense; other taxpayers cannot.
In practice the interest charge is modest enough that the rate arbitrage from converting ordinary income into qualified dividends usually swamps it. Businesses with very large deferred balances should still watch the compounding, since at some point distributing income and paying the dividend tax costs less than continuing to defer.
Setting One Up and Keeping It Qualified
Forming an IC-DISC means incorporating a new domestic C corporation that meets the requirements of Section 992. The corporation must have only one class of stock, and the par or stated value of its outstanding stock must be at least $2,500 on every day of the tax year.11Office of the Law Revision Counsel. 26 USC 992 – Requirements of a Domestic International Sales Corporation The election is made on IRS Form 4876-A with the written consent of all shareholders. For the corporation’s first tax year, the form must be filed within 90 days after the year begins. For any later year, the election must be made during the 90-day window immediately before the first day of that tax year.12Internal Revenue Service. Form 4876-A – Election To Be Treated as an Interest Charge DISC Miss the window and the election is lost for that year.
Once operating, the IC-DISC files Form 1120-IC-DISC each year. It is classified as an information return rather than an income tax return, since the corporation owes no tax, and it is due by the 15th day of the ninth month after the tax year ends. For a calendar-year IC-DISC that means September 15.13Office of the Law Revision Counsel. 26 USC 6072 – Time for Filing Income Tax Returns The commission must be paid to the IC-DISC within 60 days of the exporter’s tax year-end. Shareholders receiving deferred DISC income file Form 8404 with their own returns to compute the interest charge.
The two 95% tests (gross receipts and export assets) have to be met every year. Falling below the threshold does not automatically kill the election. The corporation can preserve its status by making a deficiency distribution to shareholders, provided the failure was for reasonable cause and the distribution is pro rata across all shareholders.14eCFR. 26 CFR 1.992-3 – Deficiency Distributions to Meet Qualification Requirements Reasonable cause covers things like a Section 482 pricing adjustment that retroactively pushed qualified receipts below 95%, good-faith uncertainty about whether a particular receipt or asset qualified, blocked foreign currency, or an unexpected insurance recovery that inflated non-export receipts.
A safe harbor also exists. If qualified export receipts were at least 70% of gross receipts and qualified export assets averaged at least 70% of total assets throughout the year, reasonable cause is automatically satisfied, provided the deficiency distribution is made by the 15th day of the ninth month after the tax year ends. The distribution has to be designated as a deficiency distribution when it is made; an earlier dividend cannot be relabeled after the fact. Drop below 70% or fail to show reasonable cause and the election is lost, at which point all accumulated deferred DISC income becomes immediately taxable to shareholders. That is the outcome to watch for throughout the year rather than to discover at year-end.
