A tax form shaped like Inky, the blue ghost from Pac-Man, with cartoon eyes, set against a bright yellow background.

Recognized before it’s received.

Phantom income is taxable income that must be reported to the Internal Revenue Service even though no cash has been received. It typically occurs when you recognize income for tax purposes as it accrues, rather than when it is paid out.

How different investments are taxed

Investments aren’t all taxed the same way. Some assets—such as stocks and real estate—are taxed on a realization basis. You generally owe taxes only when you sell the asset. Any capital gain or loss is based on the difference between the sale price and the adjusted cost basis, and taxes are deferred until the asset is disposed of. Other investments are taxed on an accrual basis, meaning income is recognized as it is earned, even if no cash is received. This is where phantom income comes into play.

For example:

Pass-through investments, including partnerships, private equity, private credit funds, and other alternative assets, may allocate taxable income to investors regardless of whether cash distributions are made.
Zero-coupon bonds and other bonds issued at a discount to par value—known as original issue discount (OID) bonds—generate interest that accrues over time and is taxed annually, even though no payments are made until maturity.
Treasury Inflation-Protected Securities (TIPS) increase in principal as inflation rises, and those increases are taxed each year.

Cash vs. accrual accounting

Income can be recorded in two ways:

Cash basis. Revenue is recognized when cash is received.
Accrual basis. Revenue is recognized when it’s earned, regardless of when cash is paid.

Most businesses use accrual accounting. Phantom income follows the same idea—income is recognized before cash is received. Learn more about the two accounting methods.

Accrual vs. mark-to-market

Phantom income is distinct from mark-to-market (MTM) taxation, in which assets are revalued annually and taxes are based on current market prices, typically as of the last business day of the year. Mark-to-market rules apply in limited cases such as regulated futures contracts, some exchange-traded options, or for traders who elect MTM treatment.

Unlike mark-to-market taxation, phantom income reflects a partial accrual approach. The asset itself may not be fully revalued each year, but specific components of its return—such as accrued interest on a bond or allocated income from a partnership—are still taxed annually.

Understanding whether an investment is taxed on a realization, accrual, or mark-to-market basis can help you anticipate when income will be taxed—and whether cash will be available to pay the resulting tax liability.

Why phantom income matters

Phantom income can create a mismatch between your company’s (or your household’s) tax liability versus its cash flow. In some cases, you may owe taxes on money you haven’t received, which means you’ll need to cover the tax bill using other funds.

That’s why investments that generate phantom income—such as OID bonds, partnership interests, and TIPS—tend to fit better in tax-advantaged accounts or alongside assets that produce steady cash flow. If you hold them in a taxable account, it helps to plan ahead—because with phantom income, the tax bill doesn’t wait for the payout.
