What this result does not account for
- Federal treatment; state rules and rates differ.
- QBI is applied at the headline twenty per cent without the wage and property limitations.
- Assumes level depreciation — the first and final part-years differ.
In short: Depreciation shelters cash without touching it. 24,509.57 of cash flow reports only 2,376.39 of taxable income, an effective 3.1026% on cash against a 32% marginal rate — because depreciation exceeds principal by 22,133.18.
Formula
taxable = NOI − interest − depreciation
shelter = depreciation − principal
[('interest', 'debt service less principal — only this is deductible'), ('depreciation', 'a deduction with no cash outlay'), ('principal', 'a cash outlay with no deduction'), ('allowance', '25,000, phasing out from 100,000 of MAGI')]
Worked Example
- Split debt service into interest and principal.
- Deduct interest and depreciation from net operating income.
- Compare that against the cash the property actually produced.
- Apply passive loss limits if the result is a loss.
- Net the annual shelter against recapture at the exit.
84,240 of NOI with 59,730.43 of debt service produces 24,509.57 of cash. Interest is 50,928.34 once 8,802.09 of principal is removed, and after 30,935.27 of depreciation the taxable income is only 2,376.39 — the shelter of 22,133.18 is exactly depreciation less principal. Tax at 32% is 760.44, an effective 3.1026% on cash. At 120,000 of MAGI the passive allowance is 15,000, half phased out. Ten years of depreciation carries 77,015.94 of recapture against 98,580.40 of shelter taken — a net 21,564.46 plus a decade of deferral.

Methodology & Editorial Standards
Taxable income is net operating income less deductible interest and depreciation, where interest is debt service less principal — the split that most first-year filers get wrong. The shelter is reported as the difference between cash flow and taxable income and shown to equal depreciation less principal exactly. Losses are tested against the twenty-five thousand special allowance phasing out at fifty cents per dollar from one hundred thousand of MAGI, with the excess described as suspended rather than lost. Recapture is projected at the twenty-five per cent ceiling and netted against the shelter taken.
Computation runs in IEEE-754 double precision at full internal precision; rounding to two decimal places occurs strictly at the display layer, so no cumulative drift enters the result. All monetary outputs use accounting presentation — grouped thousands, two decimals, negatives in parentheses — so figures can be transcribed directly into a model or working paper. Division-by-zero and out-of-domain inputs return an em-dash rather than a misleading number.

Real Estate Tax Savings Calculator — 10 Expert FAQs
10 analyst-written answers to the questions practitioners actually ask — optimised for voice and answer-engine retrieval.
How does rental property save tax?
Chiefly through depreciation, which is a deduction requiring no cash outlay. Because principal repayment is a cash outlay that is NOT deductible, the shelter is precisely depreciation minus principal. That difference is why a rental can distribute real money while reporting almost no taxable income.
Why is my taxable income lower than my cash flow?
Because depreciation is deducted but not paid, while principal is paid but not deducted. Early in a loan, depreciation typically far exceeds principal, so taxable income sits well below cash. The gap narrows every year as the loan amortises and principal grows.
What is the passive activity loss limit?
Rental losses are passive and generally cannot offset wages or portfolio income. An active participant may deduct up to twenty-five thousand, but that allowance phases out at fifty cents per dollar of income above one hundred thousand and disappears entirely at one hundred and fifty thousand.
What happens to suspended losses?
They are suspended, not lost. They carry forward indefinitely and release in full in the year you dispose of the property in a fully taxable transaction. This can make the exit year unexpectedly efficient, offsetting some of the gain and recapture that arrives at the same time.
Can rental income qualify for QBI?
It can if the activity rises to a trade or business, and a safe harbour exists for enterprises meeting hour and record-keeping requirements. Where it applies, it deducts a fifth of qualified income. A single passive rental with a management company often will not qualify.
What is real estate professional status?
A test based on hours spent in real property trades or businesses which, if met, makes your rental activities non-passive and removes the loss limitation entirely. The thresholds are demanding and the substantiation requirements are strict, and it is one of the most frequently examined positions in the code.
Is my mortgage payment deductible?
Only the interest portion. Principal is repayment of borrowed money rather than an expense, and deducting the whole payment is the most common error on a first rental return. Your amortisation schedule gives the split, which changes every month.
Should I count depreciation as income?
Never. It is a non-cash deduction, so adding it back into a cash flow projection double-counts it. It reduces the tax you pay on cash you already received; it does not produce cash of its own.
What is the effective tax rate on a rental?
Usually far below your marginal rate, because depreciation shelters most of the cash. This page computes tax as a share of actual cash flow rather than of taxable income, which is the comparison that matters when weighing a rental against an after-tax return elsewhere.
Does this shelter last forever?
No. Depreciation ends after twenty-seven and a half years, principal grows every year so the shelter shrinks, and recapture at up to twenty-five per cent arrives at the sale. The benefit is a rate arbitrage plus deferral, and it must be netted against that eventual bill.
