IRS Form 1120 (Schedule PH) – Personal holding companies (PHCs) face a special 20% tax on undistributed income to prevent high-income individuals from using corporations to shelter passive earnings at lower corporate rates. IRS Form 1120 Schedule PH calculates and reports this Personal Holding Company (PHC) Tax. Closely held corporations with significant passive income—such as dividends, interest, rents, or royalties—must understand this form to avoid unexpected liabilities and compliance issues.
This comprehensive guide, based on official IRS sources (including the current Schedule PH (Form 1120) Rev. November 2015 and Instructions Rev. December 2016, still applicable for tax years 2025 and 2026), explains everything corporations need to know. It covers PHC tests, computation steps, filing requirements, and strategies to minimize or eliminate the tax.
What Is IRS Schedule PH (Form 1120)?
Schedule PH is an attachment to Form 1120, U.S. Corporation Income Tax Return. It figures the PHC tax imposed under IRC Section 541 on a corporation’s undistributed personal holding company income (UPHCI).
The tax rate is a flat 20% on UPHCI. This rate has remained unchanged since the form’s revision and applies regardless of the regular corporate tax rate (currently 21% flat rate post-TCJA).
A corporation must complete and attach Schedule PH if it meets the definition of a personal holding company for the tax year.

Who Must File Schedule PH? The Two PHC Tests
A corporation qualifies as a PHC—and must file Schedule PH—only if it satisfies both of these tests (per IRC Section 542(a)):
- Income Test (PHC Income Test)
At least 60% of the corporation’s adjusted ordinary gross income (AOGI) for the tax year consists of personal holding company income (PHCI). - Stock Ownership Test
At any time during the last half of the tax year, five or fewer individuals own (directly or indirectly) more than 50% in value of the outstanding stock.
Certain entities count as “individuals” for the ownership test, including qualified pension plans, certain trusts, private foundations, and portions of trusts set aside for charitable purposes.
How to Apply the Income Test: The IRS Worksheet?
The Instructions for Schedule PH include a Worksheet for Figuring Ordinary Gross Income, Adjusted Ordinary Gross Income, and the PHC Income Test. Corporations must complete this worksheet (even if not filing the full schedule) to determine PHC status.
- Start with total gross income (Section 61).
- Subtract capital gains and Section 1231 gains → Ordinary gross income.
- Subtract specific adjustments (e.g., rent-related deductions, certain royalty deductions, excluded interest) → Adjusted ordinary gross income (AOGI).
- Compute PHCI percentage: (PHC income from Part II, line 25) ÷ AOGI.
- If ≥ 60% and the stock test is met → the corporation is a PHC.
PHC Income (PHCI) primarily includes:
- Dividends (with limited exclusions, e.g., from controlled foreign corporations)
- Interest (with exclusions for certain broker/dealer or condemnation-related interest)
- Rents (subject to complex exclusion rules if rents ≥ 50% of AOGI and distributions meet thresholds)
- Royalties (mineral, oil, gas, copyright—with specific exclusion tests)
- Produced film rents
- Compensation for use of corporate property by 25%-or-more shareholders
- Amounts from personal service contracts where the performer owns 25%+ of stock
- Income from estates and trusts
Certain rents, royalties, and film rents can be excluded from PHCI if strict tests (income thresholds + distribution requirements + expense ratios) are met.
Stock Ownership Test Details (Part IV of Schedule PH)
List the names and addresses of individuals (or qualifying entities) who, together, owned >50% of the stock value in the last half of the year. Report percentages for preferred and common stock separately.
Exceptions: Corporations That Are Never PHCs
Even if both tests are met, the following are explicitly not personal holding companies:
- Tax-exempt organizations
- Banks, domestic building and loan associations, and certain lending/finance companies
- Life insurance and surety companies
- Small business investment companies licensed under the Small Business Investment Act of 1958
- Corporations in bankruptcy (Title 11 or similar cases)
- Foreign corporations
How the PHC Tax Is Calculated (Parts I–III)?
Part I – Undistributed Personal Holding Company Income
Starts with taxable income (before NOL and special deductions from Form 1120, line 28) and makes adjustments:
- Additions: Charitable contributions deducted on Form 1120; excess expenses/depreciation from Part V.
- Deductions: Federal/foreign income taxes paid (not PHC or accumulated earnings tax); charitable contributions (using individual limits); prior-year NOL; net capital gain minus related tax; dividends-paid deduction (from Part VI).
Result on line 13 = undistributed PHC income.
Part II – Personal Holding Company Income
Breaks down each category of PHCI with exclusions and adjustments. Total flows to the worksheet and Part I.
Part III – Tax Computation
Line 26: Undistributed PHC income (Part I, line 13) × 20% = PHC tax.
Enter this on Schedule J (Form 1120), line 8 (or equivalent line on the return).
The Critical Role of the Dividends-Paid Deduction (Part VI)
The most effective way to reduce or eliminate PHC tax is the dividends-paid deduction under Sections 561 and 562. This includes:
- Taxable dividends actually paid during the year
- Consent dividends (via Forms 972/973)
- Dividend carryover from prior 2 years
- Dividends paid in the first 2½–3½ months after year-end (with election; rules differ slightly for June fiscal years)
Distributing sufficient dividends can bring undistributed PHC income to zero.
Step-by-Step: How to Complete and File Schedule PH?
- Determine PHC status using the worksheet.
- If required, complete Parts I–VI of Schedule PH.
- Attach all required schedules (e.g., for rent/royalty adjustments, excess expenses, dividend computations).
- Attach the completed Schedule PH to Form 1120.
- File by the regular corporate deadline (15th day of the 4th month after year-end for calendar-year corporations; extensions available via Form 7004).
Important: If the corporation is a PHC but fails to file Schedule PH, the statute of limitations for assessment extends to 6 years after the return is filed (Section 6501(f)).
Penalties and Consequences of Non-Compliance
- Failure to self-assess and report the PHC tax can trigger accuracy-related penalties (Section 6662).
- Extended assessment period increases audit risk.
- The PHC tax is in addition to regular corporate income tax (though it reduces accumulated earnings tax exposure in some cases).
Tips to Avoid or Minimize PHC Tax in 2025–2026
- Monitor passive income percentage early in the year.
- Increase active business income or adjust investment mix.
- Pay timely dividends (document properly).
- Consider S corporation election (S corps are not subject to PHC tax).
- Consult a tax professional for complex rent/royalty exclusions or foreign ownership issues.
- Track stock ownership changes, especially in the second half of the year.
Note: Rules have remained stable post-TCJA. Always verify with the latest Form 1120 instructions for any indirect impacts.
Conclusion: Stay Compliant with Schedule PH
For corporations meeting the PHC definition, IRS Form 1120 Schedule PH is mandatory. Proper planning—especially around dividend distributions—can eliminate the 20% tax entirely. Ignoring it risks penalties and prolonged IRS exposure.
