Schedule A (Form 990-T) is the worksheet a tax-exempt organization uses to report the income and deductions of a single unrelated trade or business. Every Form 990-T needs at least one Schedule A attached, and an organization that runs more than one unrelated business files a separate Schedule A for each activity. The schedule moves from gross receipts through cost of goods sold and allowable deductions to arrive at taxable income (or a reportable zero) for that one activity.
Who Files a Schedule A
Any tax-exempt organization with $1,000 or more in gross income from an unrelated trade or business during the tax year has to file Form 990-T and attach a Schedule A for each separate business activity.1Internal Revenue Service. Unrelated Business Income Tax
The rule that shapes the whole exercise sits in Section 512(a)(6): an organization with more than one unrelated trade or business must compute taxable income separately for each one, and a loss in one activity cannot offset a gain in another.2Office of the Law Revision Counsel. 26 USC 512 – Unrelated Business Taxable Income Each Schedule A is a self-contained profit-and-loss statement for its activity. If the math produces a negative number, you report zero for that activity; you do not carry the loss over to another Schedule A.
Activities That Don’t Need a Schedule A
Some commercial-looking activities are excluded from unrelated business income by statute, so check these before you start filling anything out. If an activity qualifies, its income doesn’t count toward the $1,000 filing threshold and you don’t prepare a Schedule A for it.
- Volunteer labor. If substantially all the work is performed by unpaid volunteers, the income isn’t subject to UBIT. Courts look at the ratio of volunteer hours to compensated hours, and “compensation” is read broadly to include wages, benefits, and even discounted goods received for services.3Internal Revenue Service. Volunteer Labor Exclusion From Unrelated Trade or Business
- Convenience of members. A business run by a 501(c)(3) or a government college primarily for the convenience of its members, students, patients, or employees is excluded. A campus cafeteria is the classic example.4Internal Revenue Service. Unrelated Business Income Tax Exceptions and Exclusions
- Donated merchandise. Selling goods the organization received as gifts or contributions, as long as substantially all the merchandise was donated, is not an unrelated trade or business.4Internal Revenue Service. Unrelated Business Income Tax Exceptions and Exclusions
Grouping Activities With NAICS Codes
The IRS uses the North American Industry Classification System to decide which activities share a Schedule A and which need their own. Under 26 CFR 1.512(a)-6, you identify each separate unrelated trade or business using the first two digits of the NAICS code that most accurately describes it.5eCFR. 26 CFR 1.512(a)-6 – Special Rule for Organizations With More Than One Unrelated Trade or Business Two activities sharing the same two-digit code go on one Schedule A. Different two-digit codes mean separate schedules.
Start at the six-digit level in the NAICS manual at census.gov, then roll up to the two-digit sector. A pharmacy open to the public and a gift shop both fall under retail trade (sector 44-45) and would share one Schedule A. A rental property (sector 53, Real Estate) and that same gift shop would each need their own.
Each two-digit code can appear only once across all your Schedules A. Three pharmacies in three locations still produce one retail-trade Schedule A. Investment activities that don’t fit any NAICS sector use the separate non-NAICS business activity codes listed in the Form 990-T instructions.
Header Items A Through E
Items A and B ask for the organization’s name and EIN, which must match Form 990-T. Item C is the business activity code, and the IRS e-filing system requires a full six digits. For a NAICS-based code, enter the two-digit sector followed by four zeros: retail trade (NAICS 45) becomes 450000. For a non-NAICS investment code, enter the full six-digit code from the instructions.6Internal Revenue Service. Instructions for Form 990-T Item D wants a brief written description of the activity, specific enough to identify what the business actually does.
Part I: Unrelated Trade or Business Income
Part I captures the revenue side. Line 1a is gross receipts from sales of goods or services generated by this activity. If the business sells merchandise, you compute cost of goods sold in Part III and subtract it to arrive at gross profit. The remaining lines in Part I cover other income attributable to this activity, including capital gains, rents, and interest. The total on Part I, line 13, feeds the deductions calculation in Part II.
Part III: Cost of Goods Sold
Complete Part III if the activity produces or purchases merchandise for sale. The section begins with beginning-of-year inventory, adds purchases and labor costs during the year, subtracts ending inventory, and produces cost of goods sold. Inventory valuation must follow your chosen accounting method consistently, whether that’s cost, lower-of-cost-or-market, or another method permitted under the regulations.
Part II: Deductions Not Taken Elsewhere
Part II is where you claim expenses against the income reported in Part I. The available deduction lines cover compensation of officers (line 1), repairs and maintenance (line 3), bad debts from uncollectible receivables of the unrelated business (line 4), interest with a separate statement attached (line 5), taxes and licenses (line 6), depreciation including any Section 179 election (line 7), depletion for natural resource activities (line 9), contributions to deferred compensation plans (line 10), employee benefit programs (line 11), and other deductions as a catch-all for amortization and other authorized items without a dedicated line (line 14).
After totaling deductions, line 17 lets you apply a net operating loss carried forward from prior years on this same Schedule A. Line 18 produces the final unrelated business taxable income for this activity. A negative result is reported as zero, and the loss cannot move to a different Schedule A.2Office of the Law Revision Counsel. 26 USC 512 – Unrelated Business Taxable Income
Smaller filers get a shortcut. If combined gross income across all your Schedules A totals $10,000 or less, you don’t have to complete Part II, lines 1 through 14. You still fill in the remaining lines of Part II to report the final taxable income figure.7Internal Revenue Service. Instructions for Form 990-T
Allocating Shared Expenses
Staff, office space, and equipment often serve both the exempt mission and the unrelated business. Treasury Regulation 1.512(a)-1(c) requires shared expenses to be allocated between exempt and unrelated uses on a reasonable basis, and the portion assigned to the unrelated business is deductible only if it has a proximate and primary relationship to that business.8Internal Revenue Service. Unrelated Business Income Allocations
The IRS doesn’t prescribe a single formula. Common approaches allocate by percentage of floor space used, percentage of employee time spent, or percentage of revenue generated by each function. Pick a method, apply it consistently from year to year, and keep documentation of the calculation. Switching methods when the result is more favorable in a given year invites scrutiny.
Losses Stay in Their Silo
When an unrelated trade or business produces a loss for the year, it stays within its own silo. It cannot offset income on a different Schedule A, but it can be carried forward as a net operating loss deduction on the same Schedule A in future years, entered on Part II, line 17.9Internal Revenue Service. FAQs – Carryback of NOLs by Certain Exempt Organizations
NOLs from tax years beginning before January 1, 2018, follow older rules and can be deducted against aggregate UBTI without siloing. Any NOL arising in a tax year beginning after December 31, 2017, must stay with the specific activity that generated it. Keep clear records of which NOLs belong to which silo.
Where the $1,000 Specific Deduction Goes
Schedule A does not include the $1,000 specific deduction. After computing UBTI separately on each Schedule A, you add the amounts together on Form 990-T and then subtract the flat $1,000 under Section 512(b)(12) once at the Form 990-T level.2Office of the Law Revision Counsel. 26 USC 512 – Unrelated Business Taxable Income
Filing Electronically
Form 990-T and every attached Schedule A must be filed electronically. The Taxpayer First Act ended paper filing for tax years ending December 2020 and later.10Internal Revenue Service. E-File for Charities and Nonprofits You’ll file through an IRS Authorized e-File Provider that supports exempt organization returns on the Modernized e-File (MeF) system. Tax professionals who plan to transmit these returns must register through the IRS e-Services portal at least 45 days before filing.
Deadline and Extensions
For tax-exempt corporations, the return is due on the 15th day of the 5th month after the close of the tax year. A calendar-year organization’s deadline is May 15.11Internal Revenue Service. Return Due Dates for Exempt Organizations – Form 990-T (Corporations) If the due date falls on a weekend or federal holiday, it moves to the next business day. Trusts follow the same fifth-month pattern.12Internal Revenue Service. Return Due Dates for Exempt Organizations – Form 990-T (Trusts)
File Form 8868 for an automatic six-month extension of time to file.13Internal Revenue Service. About Form 8868, Application for Extension of Time To File an Exempt Organization Return The extension does not push back the payment deadline. Estimate what you owe and pay by the original due date to avoid interest, which accrues from the original due date until the balance is paid.14Office of the Law Revision Counsel. 26 USC 6601 – Interest on Underpayment, Nonpayment, or Extensions of Time for Payment, of Tax
Estimated Tax
If your organization expects unrelated business income tax of $500 or more for the year, quarterly estimated payments are required.15Internal Revenue Service. Estimated Tax: Unrelated Business Income For calendar-year organizations in 2026, the quarterly deadlines are April 15, June 15, September 15, and January 15 of the following year. Use Form 990-W to calculate the amount and pay through the Electronic Federal Tax Payment System at eftps.gov.16U.S. Department of the Treasury. Electronic Federal Tax Payment System Underpayment triggers a penalty at a rate that fluctuates quarterly.
Late Filing Penalties
Failure-to-file penalties are inflation-adjusted each year. For returns required to be filed in 2026, the figures are:17Internal Revenue Service. Rev. Proc. 2024-40
- Organizations with gross receipts of $1,309,500 or less: $25 per day the return is late, capped at the lesser of $13,000 or 5 percent of gross receipts for the year.
- Organizations with gross receipts above $1,309,500: $130 per day, capped at $65,000.
- Responsible persons: a manager or other person responsible for the failure can face a separate penalty of $10 per day, up to $6,500.
The penalty applies once per late Form 990-T, not per attached Schedule A. Repeated failures can put the organization’s exempt status at risk.
Public Inspection for 501(c)(3) Filers
Section 501(c)(3) organizations must make Form 990-T available for public inspection, including all schedules and attachments related to the unrelated business income tax. Your Schedule A filings are part of the public record.18Internal Revenue Service. Public Inspection and Disclosure of Form 990-T The requirement applies to returns filed after August 17, 2006, and the organization must keep them available for three years from the filing deadline, including extensions. Schedules and attachments unrelated to UBIT do not have to be disclosed.
