Phantom Income: Why Profitable Rentals Show a Tax Loss (and Vice Versa)

By Tom, CPA · Updated October 27, 2026

TL;DR: Rental cash flow and taxable income diverge because depreciation is a deduction without a cash outlay, while mortgage principal is a cash outlay without a deduction. Early on, depreciation usually wins and rentals show tax losses. Later, as principal payments grow and depreciation runs out, landlords can owe tax on income they never saw.

Educational only, not tax, legal, or investment advice. Examples are illustrations, not predictions. Rules and limits change; verify current figures and talk to a qualified professional about your situation.

Your tenant pays the mortgage; the IRS pays for the roof, eventually, over 27.5 years. The mismatch in that sentence is the whole story of this page. The tenant's rent pays both interest and principal, but only the interest is deductible. The roof cost you cash years ago, but the deduction drips out slowly.

The result is a landlord who looks at the bank account and the tax return and sees two different businesses. Understanding why keeps you from panicking when the tax bill shows up in year 20 and from celebrating too early in year one.

CPA Warning Label: Phantom income is not a penalty for doing something wrong. It is the bill for deductions you already enjoyed, arriving with no cash attached.

Principal isn't deductible

A mortgage payment has two parts. Interest is a deductible rental expense on Schedule E (IRS Publication 527). Principal is repayment of a loan; you already got the "deduction" for it through depreciation on the property you bought with the borrowed money. Deducting principal too would be counting the same dollar twice.

On a standard amortizing loan, early payments are mostly interest and later payments are mostly principal. So as the years pass, a level monthly payment produces a shrinking interest deduction, even though the cash going out the door stays the same.

Depreciation isn't cash

Depreciation is a deduction for wear and tear on the building, spread over 27.5 years for residential rentals (Publication 946). You do not write a check for it each year. That is why it can turn positive cash flow into a tax loss. It also stops: once a component is fully depreciated, its deduction ends, while rent keeps coming.

Bonus depreciation and cost segregation make this more dramatic. Front-loading deductions into year one creates a big early tax loss and leaves less depreciation for later years. As of October 2026, 100% bonus depreciation is available for qualified property acquired after January 19, 2025 (IRS Notice 2026-11), so the front-loading can be large.

Cash flow vs taxable income table

Numbers make this click faster than prose. Illustration: A rental bought for $400,000 with $80,000 down; building basis $320,000 (land $80,000). A 30-year loan of $320,000 at 6.5% has a payment of about $24,271 a year. Rent $36,000; taxes, insurance, repairs and management $10,000. Depreciation about $11,636 a year ($320,000 / 27.5). Interest figures are approximate from a standard amortization schedule.

Rent and expenses are held flat to isolate the effect; in real life both usually rise. In year 1 the landlord pockets $1,729 and reports a $6,331 loss. In year 29, the same $1,729 of cash flow comes with $23,695 of taxable income. At a 22% bracket that is about $5,200 of tax on $1,729 of cash. That is phantom income.

Late-life phantom income

Three forces combine late in a holding period:

• Depreciation ends for the building after 27.5 years, and much sooner for cost seg components.
• Interest shrinks as the loan amortizes.
• Rents typically rise with inflation while the payment stays flat.

Suspended passive losses from early years can soften the blow, because they offset future passive income from the same activity or others. A landlord who could not use early losses (high income, no REPS) may find those carryforwards absorb much of the later phantom income. That is one of the few cheerful features of the passive loss rules (Publication 925).

Phantom income also shows up at sale. If debt exceeds basis, sale proceeds may go mostly to the lender while taxable gain is large, because gain is measured from adjusted basis, not from equity. The same can happen in a foreclosure or short sale.

Phantom income in partnerships and syndications

Investors in real estate partnerships and syndications meet phantom income from a different angle. A partnership reports each partner's share of taxable income on Schedule K-1 whether or not it distributes cash. A syndication that refinances and holds cash for reserves, or pays down debt aggressively, can allocate taxable income to partners who received little or nothing.

The reverse is common in early years: cost segregation and bonus depreciation inside the partnership can produce K-1 losses while the partnership distributes cash. Those losses are passive for most limited partners, and distributions in excess of a partner's basis are taxable as gain. Read the K-1 alongside the distribution statement, not in place of it.

At sale, the "capital account" story matters. A partner whose share of partnership liabilities is relieved on sale is treated as receiving cash equal to that relief (Publication 544 treats debt relief as part of the amount realized). That is why some partners owe tax on a sale that produced a small check.

Foreclosures, short sales and debt payoffs

Phantom income's scariest form is a disposition where the owner walks away with nothing and still owes tax. When a property is foreclosed or sold short, the amount realized includes debt relieved. For recourse debt, the excess of debt over fair market value may be cancellation of debt income, while the rest is treated as a sale; for nonrecourse debt, the full debt is generally included in the amount realized (Publication 544). Depreciation previously taken lowers basis, enlarging the gain.

Illustration: An investor owes $300,000 of nonrecourse debt on a rental with an adjusted basis of $180,000 after years of depreciation. The lender forecloses. Amount realized: $300,000. Gain: $120,000, much of it unrecaptured 1250 gain, even though the investor received no cash. Suspended passive losses from the property, if any, are released in the same year and may offset part of it.

Planning

• Expect it. Project taxable income, not just cash flow, before buying and every few years after.
• Refinancing restarts the amortization schedule and increases interest deductions, but only interest traced to rental use is deductible on Schedule E.
• A 1031 exchange into a larger property brings new depreciable basis (excess basis from additional investment), resetting some of the shelter.
• Improvements add new depreciation; so do appliances and other short-lived assets.
• Paying off the loan early increases taxable income further (less interest) while freeing cash flow. That trade-off is fine, just budget for it.
• Holding until death lets heirs reset basis to fair market value under Section 1014, ending the cycle for the next owner.

The other direction: tax loss with real money

The flip side of phantom income is a "paper loss" landlord with real cash flow. Illustration: in year 1 above, the landlord has $1,729 of cash plus $3,577 of principal paydown (wealth building) while reporting a $6,331 loss. If that loss is usable, say through the $25,000 allowance for an active participant with modified AGI under $100,000, it also saves about $1,393 at a 22% bracket. Economic profit roughly $6,700; tax return says loss. Neither number alone tells you if the investment is good. Track three numbers each year: cash flow, taxable income, and principal paid. Together they show what the property is really doing, and they make the year-20 tax bill a forecast instead of a surprise.
