Form 990-T (2010): Exempt Organization Tax Return
Checklist
Form 990-T 2010 is an IRS tax form used by tax-exempt nonprofits to report and pay federal taxes on unrelated business taxable income. It applies to nonprofit organizations, private foundations, and certain trusts required to file information returns under the Internal Revenue
Code.
Purpose of Form 990-T Within the Form 990 Series
Form 990-T is part of the broader Form 990 Series, which includes IRS Form 990, Form 990-EZ
(Short Form), Form 990-N, and Form 990-PF. Unlike the Return of Organization Exempt from
Income Tax, Form 990-T focuses specifically on unrelated business income subject to income taxes rather than exempt activities.
Who Must File Form 990-T 2010
Tax-exempt organizations recognized under IRC sections 501(c), 521, 529(a), or 4947(a)(1)
must file Form 990-T if they have $1,000 or more in gross unrelated business income during the taxable year. Public charities, private foundation entities, and nonexempt charitable trusts must comply with this requirement, even if they maintain their overall tax-exempt status.
Trusts such as individual retirement accounts, simplified employee pensions, and Coverdell education savings accounts are also subject to Form 990-T filing when unrelated business income thresholds are met.
Understanding Unrelated Business Taxable Income
Unrelated business taxable income includes gross income from a regularly carried-on trade or business that is not substantially related to the organization’s exempt purpose. Income calculations begin with gross receipts, reduced by directly connected expenses, and adjusted under IRC section 512(b) before determining final taxable income.
Income excluded under the tax code includes certain dividends, interest, royalties, and capital gains, unless those amounts are generated through debt-financed property or controlled organizations.
Step-by-Step Filing Checklist
Step 1: Verify Filing Requirement
Confirm the organization holds tax-exempt status under IRC section 501(a) and generated at least $1,000 in gross unrelated business income during the fiscal year. Gross income is calculated by subtracting the cost of goods sold from gross receipts for each unrelated activity.
Step 2: Gather Required Documentation
Assemble accounting records related to unrelated business activities, including profit and loss statements, depreciation schedules, and charitable contribution substantiation. Supporting documentation must clearly tie income and expenses to unrelated business operations for accurate financial reporting.
Step 3: Complete Schedule A
Report each unrelated trade or business separately on Schedule A using appropriate Internal
Revenue Code classifications. Enter gross income, cost of goods sold, and directly connected deductions to determine net income or loss for each activity.
Step 4: Apply IRC Section 512(b) Modifications
Exclude statutory income items such as dividends, interest, annuities, and royalties that are exempt under IRC section 512(b). These exclusions apply unless the income is related to debt-financed property or controlled organizations subject to unrelated business income tax rules.
Step 5: Calculate Deductible Expenses
Deduct only expenses that have a direct and primary relationship to unrelated business activities. Shared expenses must be reasonably allocated between exempt functions and unrelated business operations, with only the attributable portion deducted.
Step 6: Attach Schedule I for Exploited Activities
Complete Schedule I if unrelated business income results from exploiting an exempt activity.
Report gross income and directly connected expenses related to the exploited activity as required for nonprofit tax returns.
Step 7: Determine Applicable Tax Rate
Apply the correct tax rate based on organizational structure using Part III of Form 990-T.
Corporations use corporate income tax rates, while trusts apply trust tax rates to determine federal tax liability.
Step 8: Calculate Estimated Tax Payments
Use Form 990-W to calculate estimated tax payments if the expected tax liability equals or exceeds $500. Timely payments help prevent penalties and interest during tax season.
Step 9: Complete Required Schedules
Attach all applicable schedules, including Schedule C for rental income, Schedule E for debt-financed income, Schedule F for controlled organization income, and Form 4562 for depreciation. These schedules support amounts reported on the main tax form.
- Wrong Schedule for Exploited Activities: Organizations often report exploited exempt
- Ignoring Entity-Specific Tax Rates: Applying corporate tax rates to trusts or trust rates
- Omitting the $1,000 Specific Deduction: Many filers fail to claim the $1,000 specific
- Including Excluded Passive Income: Dividends, interest, and royalties are often
- Overlooking Trust AMT Rules: Trusts sometimes fail to evaluate alternative minimum
- Full IRS transcript retrieval (Wage & Income + Account)
- Professional tax form review
- Preparation & filing support
- Tax relief options if you owe the IRS
Step 10: Sign and File the Return
Ensure an authorized officer signs Form 990-T before submission. File by the 15th day of the fifth month after the taxable year ends, or request an extension using Form 8868 before the extension deadline.
Filing Method and Record Retention
Form 990-T may be completed using accounting software and filed in approved digital formats or as a paper PDF file. Organizations should retain copies of filed returns, schedules, and supporting documents for prior years in accordance with Internal Revenue Service recordkeeping requirements.
Public Inspection and Compliance Considerations
Filed Form 990-T returns are generally subject to public inspection, similar to other nonprofit tax returns. Information may appear in tools such as Nonprofit Explorer or Charity Navigator, making accuracy essential for compliance and transparency.
