IRS SECTION 168 • 27.5-YEAR STRAIGHT LINE RECOVERY

Rental Property Calculator with Tax Depreciation

Most real estate calculators only model pre-tax cash flow. Calculate your IRS straight-line depreciation deductions, non-cash paper losses, and net taxable income on Schedule E.

How Rental Depreciation Works Under US Tax Code

1

Land Value Exclusion

Under IRS Publication 527, land never depreciates. Your cost basis must separate the physical structure (typically 80%–85% in suburban US markets) from non-depreciable raw land (15%–20%).

2

27.5-Year Straight Line

Under MACRS (Modified Accelerated Cost Recovery System), residential real estate is written off over exactly 27.5 years (approx. 3.636% deduction of building basis per year).

3

Phantom Paper Losses

Depreciation is an accounting deduction requiring zero cash outlay. It allows you to collect positive spendable rental income while reporting zero or negative taxable income on IRS Form 1040 Schedule E.

The Real Estate Tax Waterfall: Cash Flow vs. Taxable Income

1. Why Mortgage Principal Is Not Tax-Deductible

A common misunderstanding among first-time landlords is deducting the total monthly mortgage payment on taxes. The IRS only allows you to deduct mortgage interest (Line 12 on Schedule E). Mortgage principal paydown increases your balance sheet net worth and is not a deductible expense.

2. The Schedule E Real Estate Tax Formula

Our calculator models the precise accounting formula required on IRS Form 1040:

Taxable Real Estate Income = Net Operating Income (NOI) − Mortgage Interest − Annual Depreciation

3. Passive Activity Loss (PAL) Limitations (IRC §469)

When depreciation creates a negative taxable balance (paper loss), IRS Section 469 limits how much of this loss can offset active W-2 employment income:

  • Special $25,000 Allowance: Active participants can deduct up to $25,000 of rental losses against ordinary W-2 income if Modified AGI is under $100,000.
  • Phase-Out Range: The allowance phases out by $0.50 for every dollar earned between $100,000 and $150,000 MAGI.
  • Suspended Losses: Losses over the threshold carry forward indefinitely to shelter future rental profits or offset capital gains upon sale.

Frequently Asked Tax Questions

Can you depreciate a property purchased entirely with cash?

Yes. Depreciation is based solely on your acquisition cost basis and capital improvements, independent of debt. An all-cash buyer claims the exact same annual depreciation deduction as an investor using an 80% LTV mortgage.

What is depreciation recapture tax when selling?

Upon selling an asset, the IRS recaptures cumulative depreciation deducted during ownership. This portion is taxed at a maximum federal rate of 25% under Section 1250, unless deferred through an IRC §1031 exchange.

Do routine repairs count as capital improvements?

Routine maintenance (like fixing drywall or replacing a faucet) is expensed immediately in Year 1. Significant capital improvements (like replacing an entire roof or installing a new HVAC unit) must be capitalized and depreciated over their IRS recovery lifespan.

What is bonus depreciation and cost segregation?

Cost segregation studies reclassify components of a building (wiring, flooring, landscaping) into 5-, 7-, or 15-year property classes, allowing accelerated or bonus depreciation in Year 1. This strategy is most effective for properties purchased above $500,000 and is not modeled in standard straight-line calculators.

How does depreciation affect my cash-on-cash return?

Depreciation does not directly affect cash-on-cash return, which is a pre-tax, pure-cash metric. However, tax savings from depreciation shelter effectively increase your after-tax yield. Our main calculator computes both pre-tax cash flow and estimated annual tax savings side-by-side so you can model the complete picture.
