The personal holding company (PHC) tax under IRC 541 is a 20% penalty tax designed to prevent closely held C-Corporations from being used as personal investment vehicles to defer tax on passive income. A C-Corp that meets both the ownership test (5 or fewer individuals own more than 50% of the stock) and the income test (60% or more of adjusted ordinary gross income is PHC income) is a personal holding company and owes the 20% tax on undistributed PHC income.

✓Key takeaway

Personal holding company rules:

Ownership test (IRC 542(a)(2)):

More than 50% of the corporation’s outstanding stock is owned, directly or indirectly (constructive ownership under IRC 544), by 5 or fewer individuals
Constructive ownership includes: family members (siblings, spouse, ancestors, descendants), partnerships, trusts, and corporations in which the individual has an interest
Most closely held C-Corps with a single owner or small group of owners meet this test automatically

Income test (IRC 543):

At least 60% of adjusted ordinary gross income (AOGI) is PHC income
PHC income includes: dividends, interest, royalties, annuities, rents (unless the rent constitutes 50%+ of AOGI and certain dividend requirements are met), personal service contract income where the individual performing the services is designated in the contract or can be designated by someone other than the corporation, and certain mineral/oil/gas royalties
PHC income doesn’t include: active business income from goods or services (manufacturing, retail, consulting where the individual is not designated), interest on tax-exempt obligations, and rents that meet the 50% threshold with the dividend requirement

The 20% tax:

Applied to undistributed PHC income (taxable income minus dividends paid, federal income taxes, and certain other adjustments)
This is in addition to the regular 21% corporate tax
Combined rate on PHC income: 21% + 20% = approximately 37%

How to cure PHC status:

Pay dividends (the “deficiency dividend” procedure under IRC 547 allows retroactive dividends after an IRS determination)
Restructure income sources to reduce PHC income below 60%
Convert to an S-Corp (not subject to PHC tax)
Increase active business income relative to passive income

When does a legitimate business accidentally become a PHC?

Hypothetical example

Round numbers. A single-owner C-Corp was originally an active consulting business. Over time, the owner reduced consulting work and the corporation’s portfolio grew from retained earnings.

Current year income:

Consulting income: $80,000
Interest and dividend income from investments: $50,000
Rental income from a property held in the C-Corp: $40,000
Capital gains: $30,000 (not included in AOGI calculation)

PHC analysis:

Ownership test: single owner = more than 50% by 5 or fewer individuals. MET.
AOGI: $80,000 + $50,000 + $40,000 = $170,000 (capital gains excluded)
PHC income: $50,000 (interest/dividends) + $40,000 (rent, assuming it does not meet the 50% exception) = $90,000
PHC income / AOGI: $90,000 / $170,000 = 52.9%
Income test: 52.9% is below 60%. NOT MET.

The corporation isn’t a PHC this year.

Next year, consulting income drops to $40,000:

AOGI: $40,000 + $50,000 + $40,000 = $130,000
PHC income: $90,000
PHC income / AOGI: $90,000 / $130,000 = 69.2%
Income test: 69.2% exceeds 60%. MET.

Now the corporation IS a PHC.

Taxable income: $130,000
Corporate tax (21%): $27,300
Net income after tax: $102,700
If no dividends paid, undistributed PHC income: $102,700
PHC tax (20%): $20,540

Total tax: $27,300 + $20,540 = $47,840 (36.8% effective rate)

If the owner paid a $102,700 dividend, the PHC tax would be $0. The dividend would be taxed at the qualified dividend rate (15% or 20%), producing a combined corporate + shareholder tax of approximately $27,300 + $15,405 = $42,705 (32.8%). Paying the dividend is cheaper than paying the PHC penalty.

The better long-term solution: convert to an S-Corp, or transfer the investment portfolio out of the C-Corp.
