Form 1120 (Schedule PH)

A 20% penalty tax on passive income trapped in a closely held corporation – Schedule PH is the IRS’s enforcement mechanism for the Personal Holding Company rules, and most firms encounter it without warning.

Accountably Editorial Team 16 min read Mar 14, 2026 Updated Mar 14, 2026

I still remember a new client – a three-shareholder holding company with a portfolio of dividend-paying stocks and a corporate consulting contract – coming in to discuss their Form 1120. Within ten minutes of reviewing their income statement, I knew we had a Personal Holding Company problem. Nobody had run the PHC tests in five years of prior filings, and the accumulated 20% penalty exposure was significant. That engagement taught me to always run the income and ownership tests before I open the return for any closely held C corporation with passive investment income.

Key Takeaways

  • Schedule PH computes the Personal Holding Company (PHC) penalty tax of 20% on undistributed PHC income for corporations that meet both the ownership and income tests under IRC Sections 541–547.
  • Two independent tests must both be met for PHC status: the Ownership Test (five or fewer individuals own more than 50% of stock in the last half of the year) and the Income Test (at least 60% of adjusted ordinary gross income is PHC income).
  • The PHC tax is in addition to regular corporate income tax – it is a penalty on passive income hoarded inside a closely held corporation rather than distributed to shareholders.
  • Distributions to shareholders before year-end can eliminate or reduce the PHC tax. Consent dividends and deficiency dividends offer additional remedies even after the tax year closes.
  • Schedule PH is filed with the Form 1120 return – due April 15 for calendar-year corporations, with a 6-month extension available via Form 7004.
  • Quick rule you can copy into your SOP: run the PHC ownership and income tests at engagement setup for every closely held C corporation that holds significant investments, royalties, or passive rental income.

What Schedule PH Is and When to Use It

Schedule PH (Form 1120) is the computation schedule for the Personal Holding Company tax under IRC §541. The PHC tax was enacted to prevent what Congress called “incorporated pocketbooks” – wealthy individuals who would transfer investment assets to a closely held corporation, accumulate dividend and interest income at the corporate rate, and never distribute it to avoid paying individual income tax rates on passive income. Schedule PH calculates the undistributed PHC income subject to the 20% penalty tax.

The schedule is not filed by every C corporation – only those that meet the PHC definition. But the determination must be made every year, because a corporation can move in and out of PHC status as its income composition and ownership structure change. A corporation that acquired a new investor (diluting concentration below the 50% threshold) or shifted to more active service income (reducing PHC income below 60%) may no longer be a PHC even if it was one in prior years.

Who Files Schedule PH

Any domestic C corporation that qualifies as a Personal Holding Company must attach Schedule PH to its Form 1120. Foreign corporations are subject to a different provision (Section 552, the Foreign Personal Holding Company rules), which are now largely obsolete following legislative changes. S corporations are not subject to PHC rules and do not file Schedule PH. Tax-exempt organizations do not file Form 1120 and are not subject to PHC rules through this mechanism.

The Legislative Purpose

The PHC rules were designed in the early 20th century, when the individual income tax rates were significantly higher than corporate rates, making it tempting to shelter passive investment income inside a corporation. Even after the TCJA reduced corporate rates to 21%, the PHC rules remain in force because the 20% qualified dividend rate for individuals is often lower than the combined 21% corporate rate plus 20% PHC penalty, making the rules still meaningful for corporations with significant undistributed passive income.

The Two-Part PHC Test

The Ownership Test

A corporation meets the ownership test if more than 50% of the value of its outstanding stock is owned, directly or indirectly, by five or fewer individuals at any time during the last half of the tax year. Constructive ownership rules under IRC §544 apply – stock owned by a family member, partner, or trust beneficiary can be attributed to an individual. This test catches closely held corporations where a small number of people control the investment income accumulation.

The ownership test looks at any point during the last six months of the tax year. If the five-or-fewer concentration existed even briefly during that window, the test is met. This matters for corporations that underwent ownership changes during the year – selling 10% to a new investor in November may not be enough to break the concentration if the original five-or-fewer owned more than 50% through October.

The Income Test

The income test is met when at least 60% of the corporation’s adjusted ordinary gross income (AOGI) consists of personal holding company income. AOGI is ordinary gross income reduced by certain deductions (primarily depreciation, property taxes, interest, and rent paid to unrelated parties on income-producing property). PHC income includes dividends, interest, royalties, annuities, and certain rents and personal service income. The income test is recalculated every year, so a change in business operations can break PHC status even if ownership remains concentrated.

What Counts as PHC Income

Income Type PHC Income? Key Exception
Dividends Yes No general exception; always counts
Interest Yes Interest from active money-lending business may be excluded
Royalties Yes (generally) Active mineral royalties may qualify for exclusion from PHC income
Rents Conditional Excluded if rents are 50%+ of AOGI and certain dividends paid; active rental operations may qualify
Personal service contracts Yes Only if a specific individual is designated to perform the service by the customer
Annuities Yes No general exception
Active business income (sales, manufacturing) No Ordinary business operations excluded from PHC income definition

The rent exception deserves special attention. Rents are excluded from PHC income if adjusted income from rents constitutes 50% or more of AOGI and the corporation distributes as dividends an amount at least equal to the excess of non-rent PHC income over 10% of ordinary gross income. This is a common escape route for real estate-heavy corporations that meet the ownership test.

How to Complete Schedule PH

Part I – Personal Holding Company Income

Section What to Calculate Practitioner Note
Lines 1–8 Total PHC income categories (dividends, interest, rents, royalties, personal service income, annuities) Classify each income source before starting; use income statement and source documents
Line 9 Total PHC income Sum of all applicable lines from Part I

Part II – Adjusted Ordinary Gross Income

Part II computes AOGI by starting with ordinary gross income (not capital gains) and subtracting certain deductions: depreciation, depletion, property taxes, interest on corporate indebtedness allocable to property included in gross income, and rent paid on leased property used to produce rents included in PHC income. This adjusted figure is the denominator for the 60% income test.

Part III – PHC Tax Computation

Part III computes the undistributed PHC income: taxable income adjusted for certain additions and subtractions (including dividends paid, consent dividends, and prior-year deficiency dividends), then multiplied by 20% to arrive at the PHC tax. The resulting tax is entered on the Form 1120 tax liability schedule.

Deadlines, Penalties, and Filing Requirements

Consent dividend Form 972 filed by each consenting shareholder; Form 973 by the corporation
Estimated tax PHC tax is included in corporate estimated tax obligations under IRC §6655

Avoiding the PHC Tax Through Distributions

The most direct way to eliminate PHC tax liability is to distribute personal holding company income to shareholders before the end of the tax year. Dividends paid during the year reduce undistributed PHC income dollar for dollar. If the corporation distributes all of its PHC income before December 31, the undistributed PHC income is zero and no PHC tax is owed.

Dividend Timing Strategy

Plan dividend distributions by the third quarter of the year. Once the fourth quarter income picture becomes clear, top up the distribution to cover any additional PHC income generated during Q4. Do not wait until December 31 – payroll and distribution processing delays can push payments into January, which means they count for the following tax year, not the current year.

The Dividends-Paid Deduction

Under IRC §561, corporations can deduct dividends paid during the tax year when computing undistributed PHC income. This includes regular cash dividends, consent dividends, and dividends paid within 2.5 months after year-end (the “throwback” dividend rule). The 2.5-month throwback allows a corporation to make a dividend payment after year-end that still applies against the prior-year PHC income, provided the payment is made by March 15 for calendar-year corporations.

Consent Dividends and Deficiency Dividends

Consent Dividends (Section 565)

A consent dividend is a hypothetical dividend – shareholders agree to be taxed as if they received a dividend, even though no cash was actually distributed. The corporation gets a dividends-paid deduction equal to the consent amount, which reduces undistributed PHC income. Consent dividends must be documented on Form 972 (filed by each consenting shareholder) and Form 973 (filed by the corporation with the Form 1120 return). The shareholder’s basis in the corporation increases by the amount of the consent dividend, as if they received cash and immediately contributed it back.

Deficiency Dividends (Section 547)

If the IRS determines a PHC deficiency after the tax year has closed, the corporation can pay a deficiency dividend within 90 days of the determination and claim a deduction against the PHC income for that year. The corporation files Form 976 to claim the deficiency dividend deduction. While this reduces the PHC tax, it does not eliminate interest and the Section 6601 penalty, so deficiency dividends are a damage-control tool, not a planning tool. Use them when the initial assessment is unavoidable, not as a substitute for pre-year-end planning.

PHC Status and Entity Planning Considerations

When a closely held C corporation begins accumulating significant passive investment income, the PHC analysis should prompt a broader entity structure review. S corporation election, conversion to a partnership or LLC taxed as a partnership, or restructuring income streams to reduce the PHC income percentage may all be worth evaluating. These are multi-year planning discussions, not quick fixes.

S Corporation Election as an Exit Strategy

A C corporation that converts to S corporation status terminates its exposure to PHC rules going forward. However, the built-in gains tax under IRC §1374 applies to gains on assets that were appreciated when the S election was made, for a period of five years post-election. PHC income accumulated in C corporation years does not follow into the S corporation period. Plan the timing of any S election carefully in coordination with the corporation’s asset mix and capital gain exposure.

Increasing Active Income to Break the Income Test

If passive income is just above the 60% AOGI threshold, adding active business operations or service revenue can push the ratio below 60% and eliminate PHC status without any ownership restructuring. This requires genuine operational change, not just income reclassification. Document the business purpose of any new activities in case the IRS scrutinizes the shift.

Common Mistakes That Slow Things Down

  • Not running the PHC tests at all – Many preparers skip the PHC determination for corporations that appear to be ordinary C corporations. Any closely held corporation with significant dividends, interest, royalties, or personal service contracts needs a PHC test every year.
  • Using gross income instead of adjusted ordinary gross income for the 60% test – The income test uses AOGI, not total gross income. Failing to subtract allowable deductions inflates the denominator and can make a non-PHC corporation appear to fail the test. Use the Schedule PH Part II calculation exactly.
  • Missing the rent income exception – Rents that constitute 50%+ of AOGI may be excluded from PHC income under certain conditions. Missing this exception causes PHC status to trigger unnecessarily for real estate-heavy corporations.
  • Distributing dividends in January instead of December – A January distribution applies to the current year, not the prior year. Missing the December 31 deadline for in-year distributions means the corporation either needs the 2.5-month throwback dividend or a consent dividend. Both are administratively more complex than a regular distribution.
  • Not documenting consent dividend forms – Form 972 and Form 973 are required to substantiate consent dividends. Missing documentation means the dividends-paid deduction can be disallowed, restoring the PHC tax liability that the consent was supposed to eliminate. Small errors create big cleanup.
  • Ignoring constructive ownership in the ownership test – Family attribution under IRC §544 can push ownership concentration above the five-or-fewer, 50%+ threshold even when nominal ownership records show no single dominant shareholder. Always run the attribution analysis.
  • Assuming PHC rules no longer apply post-TCJA – The flat 21% corporate rate eliminated some of the rate arbitrage that originally motivated the PHC rules, but the 20% penalty tax on undistributed PHC income still applies and can create meaningful additional tax exposure for passive-income-heavy corporations.

Practical Checklists You Can Reuse

Copy these into your internal wiki or SOP.

PHC Determination Checklist (Run at Engagement Setup)

  • Pull ownership schedule – identify all individual shareholders and apply IRC §544 constructive ownership rules
  • Determine if five or fewer individuals own more than 50% of stock during the last half of the tax year
  • If ownership test fails, PHC status not met – document and move on
  • If ownership test met, proceed to income test
  • Calculate adjusted ordinary gross income (AOGI) per Schedule PH Part II
  • Identify all PHC income categories: dividends, interest, royalties, annuities, qualifying rents, personal service contract income
  • Calculate PHC income as a percentage of AOGI
  • If PHC income < 60% of AOGI, income test fails – document determination, no Schedule PH required
  • If both tests met, attach Schedule PH to Form 1120 and compute PHC tax

PHC Tax Avoidance Planning Checklist (Q3–Q4)

  • Project year-end PHC income and undistributed PHC income by October 15
  • Calculate dividend amount needed to reduce undistributed PHC income to zero
  • Schedule cash dividends to shareholders by December 15
  • If cash distribution is not feasible, prepare consent dividend documentation (Forms 972 and 973)
  • Confirm shareholders are aware of consent dividend tax impact on their individual returns
  • Document all distributions with payment dates and amounts
  • Verify Q4 income does not generate additional PHC income after distribution plan is set

Schedule PH Filing Checklist

  • Complete Part I for all PHC income categories
  • Complete Part II for AOGI computation
  • Verify 60% income test calculation is accurate
  • Apply dividends-paid deduction (cash dividends + consent dividends + throwback dividends)
  • Calculate undistributed PHC income in Part III
  • Compute 20% PHC tax and carry to Form 1120 tax schedule
  • Attach Forms 972 and 973 if consent dividends were used
  • Schedule PH attached to Form 1120 in correct sequence

For Accounting Firms – Keep Delivery Smooth While You Scale

PHC analysis is a specialized determination that most preparers perform infrequently. The result is that it can be skipped during busy season when it should not be, or completed incorrectly because the preparer has not run through the tests recently. Firms that document a PHC checklist into their corporate engagement template – run at setup, not at filing – close this gap systematically. Offshore teams trained on the PHC ownership and income tests can run the initial determination and flag exceptions for partner review, freeing senior staff for distribution planning and entity structuring conversations.

FAQs About Form 1120 Schedule PH

What is the Personal Holding Company tax?

The PHC tax is a 20% penalty tax on a C corporation’s undistributed personal holding company income under IRC §541. It applies when a closely held corporation – with five or fewer individuals owning more than 50% of stock – accumulates passive investment income (dividends, interest, royalties, and certain other income) without distributing it to shareholders. The PHC tax is separate from, and in addition to, the regular 21% corporate income tax.

What are the two tests for Personal Holding Company status?

The Ownership Test requires that more than 50% of the outstanding stock (by value) is owned by five or fewer individuals at any time during the last half of the tax year, with constructive ownership under IRC §544 applied. The Income Test requires that at least 60% of the corporation’s adjusted ordinary gross income is personal holding company income. Both tests must be met for PHC status to apply.

How can a corporation avoid the PHC tax?

Distribute personal holding company income as dividends to shareholders before December 31 of the tax year. The dividends-paid deduction reduces undistributed PHC income dollar for dollar. Consent dividends (Section 565) can be used when cash distribution is not feasible. A throwback dividend paid by March 15 of the following year also counts against the prior year’s PHC income. Deficiency dividends (Section 547) can reduce an assessed PHC deficiency after the fact but do not eliminate interest charges.

What types of income count as Personal Holding Company income?

PHC income includes dividends, interest, royalties, annuities, rents (with exceptions for active rental businesses meeting the 50% of AOGI test), and personal service contract income where a specific named individual must perform the service. Active business income from sales, manufacturing, or general services does not count. The classification of income as PHC or non-PHC is the most judgment-intensive part of the Schedule PH analysis.

What is the PHC tax rate?

The PHC penalty tax rate is 20% of undistributed personal holding company income. This applies on top of the regular 21% corporate income tax. A corporation that is a PHC and fails to distribute its passive income can face a combined effective rate of 41% on that income before any individual shareholder-level tax, making the PHC rules a significant planning consideration for investment-holding corporations.
