IRS Schedule PH (Form 1120): U.S. Personal Holding Company Tax

Schedule PH is filed by corporations classified as personal holding companies (PHCs) to calculate the personal holding company tax owed under Internal Revenue Code Section 541. This tax is intended to prevent corporations from avoiding income tax at the individual level by retaining passive income within the corporate structure.

When to Use Schedule PH

Schedule PH is required for any corporation that meets the criteria of a personal holding company as defined under IRC §542. Generally, a corporation is considered a PHC if at least:

  1. 60% of its adjusted ordinary gross income is passive income (such as dividends, interest, rents, and royalties).
  2. More than 50% of its stock is owned by five or fewer individuals during the last half of the tax year.

This form determines whether the corporation is subject to the additional PHC tax, currently imposed at a flat rate of 20% on undistributed personal holding company income.

Key Components of the Schedule

The 1120 Schedule PH is structured to compute the PHC income through a series of adjustments and exclusions:

Although the form has not been revised since November 2015, it remains valid and must be completed accurately.

How to Determine PHC Status

Corporations should conduct a two-part test annually:

  1. Ownership Test: Evaluate shareholder concentration.
  2. Income Test: Analyze the sources of gross income.

If both conditions are met, the corporation is required to file Schedule PH and pay any resulting tax unless it distributes sufficient income through dividends to avoid the liability.

Filing Notes and Compliance

The Schedule PH must be attached to Form 1120. It is important to retain supporting documentation for ownership records, income sources, and adjustments, especially if claiming any exceptions or exclusions. Failure to file or misclassification can result in IRS penalties.
