Form 8992 Schedule A: GILTI Reporting for U.S. Shareholders

Form 8992 Schedule A is the worksheet where a U.S. shareholder lists each controlled foreign corporation and enters the pro rata share of tested income or loss, qualified business asset investment (QBAI), and tested interest for each one. The column totals at the top of the schedule feed the GILTI inclusion calculation on the main Form 8992, which then flows into your income tax return under IRC Section 951A.¹

Who Has to File It

You file Form 8992 with Schedule A if you are a U.S. person who was a “U.S. Shareholder” of at least one CFC during the year. A U.S. Shareholder is any U.S. person owning 10% or more of the voting power or value of a foreign corporation’s stock, counting both direct and constructive ownership.² A CFC is a foreign corporation where U.S. Shareholders collectively hold more than 50% of voting power or value on any day of its tax year.³

Partners in domestic partnerships that hold CFC stock are generally treated as owning that stock directly, so partners may need to file individually even when the shares sit at the partnership level. The GILTI computation aggregates across every CFC you own; you do not run a separate calculation for each one.

The Three Numbers You Pull for Each CFC

Before touching Schedule A itself, gather three figures for every CFC. All three come from Schedule I-1 of that CFC’s Form 5471, which the CFC’s information return preparer should already have completed.¹

Tested Income or Tested Loss

Start with the CFC’s gross income and remove five statutory categories: Subpart F income, effectively connected income, related-person dividends, foreign oil and gas extraction income, and any income excluded under the high-tax exception.⁴ What remains is gross tested income. Subtract deductions properly allocable to that income. A positive result is tested income; a negative result is tested loss.⁵ A CFC has one or the other for the year, never both. The figure comes from line 6 of Schedule I-1 (Form 5471).

Qualified Business Asset Investment

QBAI is the average adjusted basis of the CFC’s depreciable tangible property used in its trade or business, calculated by averaging the end-of-quarter bases.⁶ The basis has to be determined under the alternative depreciation system in Section 168(g), even if the CFC uses another method for its books or other reporting. For property placed in service before the GILTI rules took effect in late 2017, recompute basis as if ADS had applied from the start. Only tested income CFCs contribute QBAI in column (g). A tested loss CFC contributes zero, though it does generate a separate “tested loss QBAI” entry in column (h) equal to 10% of what its QBAI would have been.

Tested Interest Expense and Interest Income

Pull the CFC’s interest expense and interest income that relate to tested income. These become your pro rata share of tested interest in columns (i) and (j). Together they determine “specified interest expense,” the excess of aggregate tested interest expense over aggregate tested interest income across all your CFCs.⁴ When interest income equals or exceeds interest expense, specified interest expense is zero.

How the Schedule A Columns Line Up

Schedule A gives each CFC its own row. The columns walk left to right from identification through the numbers that will be totaled at line 1:¹

Columns (a) and (b): CFC name and EIN or reference ID number. If the CFC changed its name within the past three years, include the old name in parentheses.
Columns (c) and (d): Full tested income or tested loss from Schedule I-1 (Form 5471), line 6.
Columns (e) and (f): Your pro rata share of tested income and tested loss.
Column (g): Your pro rata share of QBAI for tested income CFCs.
Column (h): The tested loss QBAI amount for any tested loss CFC, equal to 10% of what its QBAI would have been with tested income.
Columns (i) and (j): Your pro rata share of tested interest income and tested interest expense.
Column (k): The GILTI allocation ratio, filled in after you finish Parts I and II of Form 8992. For each tested income CFC, it is that CFC’s pro rata tested income divided by aggregate pro rata tested income across all your CFCs.

Line 1 totals every column. Those totals are what Form 8992 actually uses.

How the Totals Produce Your GILTI Inclusion

The math on the main form runs in three steps and uses the column totals directly.

Aggregate pro rata tested income minus aggregate pro rata tested loss gives net CFC tested income. If losses equal or exceed income, the inclusion is zero and you stop.⁴

Next, compute the net deemed tangible income return. Take 10% of aggregate QBAI (the statutory return on physical assets that Congress chose to exempt from GILTI) and subtract specified interest expense.⁷ If specified interest expense exceeds the 10% figure, the NDTIR is zero.

Finally, subtract NDTIR from net CFC tested income. The remainder is your GILTI inclusion, and it goes into gross income for the year.

The structure explains why the columns matter individually. A CFC-heavy business with substantial tangible property and low intercompany debt produces a larger NDTIR and a smaller inclusion. An asset-light structure with intangible value and internal leverage produces the largest inclusions, which is what the provision was designed to reach.

Elections That Change What Goes on the Schedule

Two elections routinely change either what appears on Schedule A or how the resulting inclusion is taxed.

The GILTI high-tax exclusion removes tested income from the schedule entirely when the effective foreign tax rate on that item exceeds 18.9% (90% of the 21% U.S. corporate rate).⁵ The election is annual and made by the CFC’s controlling domestic shareholders (generally the 10% U.S. shareholders holding more than 50% of voting power). Once made, it binds every U.S. shareholder of that CFC. The rate is tested on a CFC-by-CFC and item-by-item basis, so a single CFC operating across jurisdictions can have some income excluded and some included. A retroactive election on an amended return is allowed within 24 months of the unextended due date of the controlling shareholder’s original return, provided other shareholders file consistent amended returns within a single six-month window inside that period.

The Section 962 election lets an individual shareholder be taxed on GILTI as if they were a domestic corporation, unlocking the corporate rate and the Section 250 deduction that individuals otherwise cannot use.⁸ You attach a written statement identifying the election and the income it applies to, then file Form 8992 for the inclusion, Form 8993 for the Section 250 deduction, and Form 1116 for foreign tax credits. The election is annual. The trade-off is that GILTI escaping current U.S. tax under the election may be taxed again when the CFC eventually distributes earnings.

Filing and Where the Numbers Land on Your Return

Attach Form 8992 and Schedule A to your income tax return and file by the return’s due date, including extensions.⁹ Corporate shareholders attach to Form 1120; individual shareholders attach to Form 1040.¹ The GILTI inclusion amount reported on Form 8992 increases gross income on the corresponding line of the return.

Because Schedule A is entirely a rollup of data from each CFC’s Form 5471, the accuracy of your GILTI number depends on the accuracy of those underlying returns. Most errors that show up on Schedule A trace back to incorrect tested income figures or QBAI computed under the wrong depreciation method, not to arithmetic on the schedule itself.

Correcting a Filed Schedule A

If you find an error after filing, prepare a corrected Form 8992 with a revised Schedule A, write “Corrected” at the top, and attach a statement explaining the changes.¹ File it with the amended return that fits your original filing: Form 1040-X for individuals, Form 1120-X or a superseding Form 1120 for corporations. Common triggers include QBAI recomputed under ADS, tested income adjusted after a Subpart F reclassification, and revised pro rata share percentages after a fresh look at constructive ownership. Because the calculation aggregates across every CFC, fixing one row can move the final inclusion.

Penalty Exposure Sits on the Underlying Forms 5471

Form 8992 does not carry a standalone penalty, but the Forms 5471 that supply its data do. Failing to file a required Form 5471, or filing one that is substantially incomplete, triggers an initial $10,000 penalty per form. If the failure continues more than 90 days after IRS notice, another $10,000 accrues for each 30-day period, up to a $50,000 continuation cap, for a maximum of $60,000 per CFC per year.¹⁰ Missing Forms 5471 can also toll the statute of limitations on the entire return until they are filed. Reasonable cause is the primary defense and is evaluated case by case.¹¹ The practical takeaway for Schedule A filers is that the schedule is only as sound as the 5471 data behind it, so it is worth confirming those figures before you aggregate them.
