Non-cash deductions sheltering real cash flow from tax
Depreciation allows an owner to deduct a non-cash expense for tax purposes. On a 1 million dollar residential rental, the building depreciates at approximately 36,400 annually (1 million divided by 27.5 years), reducing taxable income even though no actual cash left the pocket. An investor collecting 50,000 in net cash flow per year reports only 13,600 to the IRS (50,000 minus 36,400 depreciation), paying tax on 13,600 while keeping the full 50,000. This 'phantom expense' shields cash flow from taxation year after year.
Recapture at sale and the long-hold advantage
When the property sells, depreciation taken is 'recaptured' at a 25% federal rate (above normal capital gains rates), clawing back the earlier tax deferral. However, for an investor with a multi-decade hold, the NPV of deferred taxes is substantial. Combined with principal paydown (another non-taxed cash reduction), depreciation shields make rental real estate uniquely tax-efficient compared to dividend stocks or bonds, explaining why landlords and institutional investors prioritize the strategy.
