Depreciation Systems
Depreciation can be calculated using either the General Depreciation System (GDS) or the Alternative Depreciation System (ADS). The recovery periods for most property are generally longer under ADS than they are under GDS.
- General Depreciation System (GDS)
- Alternative Depreciation System (ADS)
-
A slower, straight-line system used when required by law or elected. The triggers that matter for a landlord: an electing real property trade or business ( IRC §163(j)(7)(B)) must use ADS for its residential, nonresidential, and qualified improvement property; an electing farming business must use it for property with a GDS recovery period of 10 years or more ( IRC §163(j)(7)(C)); and ADS is mandatory for tax-exempt use property, property financed by tax-exempt bonds, property used in farming, and property used 50% or less in a qualified business use. You may also elect ADS voluntarily for residential rental property — but only in the first year the property is placed in service, and the election is irrevocable. The full list lives in IRC §168(g).
Strategic Tax Implications Depreciation can significantly impact your tax strategy:
- Tax Savings
-
By reducing taxable income, depreciation lowers your tax liability. Land is never depreciable, so the deduction is computed on the building basis only. On a $550,000 purchase where the assessor allocates $150,000 to land, the depreciable basis is $400,000 and the annual deduction is $400,000 / 27.5 = $14,545.
- Cash Flow Management
-
As a non-cash expense, depreciation raises cash flow by reducing taxes without affecting actual cash on hand.
- Investment Analysis
-
Depreciation affects the net income of a property, influencing investment decisions and property valuations.
Consider an individual in California who owns a $1.5 million residential rental property. Using MACRS, they can depreciate the building value (excluding land) over 27.5 years. Assuming the building’s value is $1.2 million, the annual depreciation deduction is approximately $43,636 ($1.2 million / 27.5 years). This deduction can offset rental income, potentially saving over $16,000 in taxes annually, assuming a 37% tax bracket.
Even if your rental property doesn’t generate positive cash flow initially, depreciation can create a paper loss on Schedule E. What you can do with that loss is the catch. Under the passive activity loss rules ( IRC §469, “Passive activity losses and credits limited”), a rental loss generally offsets only passive income. There is a carve-out — with active participation you may deduct up to $25,000 of the loss against ordinary income — but it phases out between $100,000 and $150,000 of modified AGI and is gone entirely above that, which is to say it is worth nothing to most readers of this book. The unused loss is then suspended and carried forward until you have passive income or sell the property.
The two ways a high earner actually puts rental losses against ordinary income are real estate professional status (section “Real Estate Professional Status”), which makes rental activity non-passive subject to strict hour tests, and the short-term-rental route, where materially participating in a rental whose average guest stay is seven days or less takes it outside the passive rules entirely (section “The Short-Term Rental Loophole”). Either way, the depreciation deducted now is recaptured — taxed at up to 25% — when you sell; a paper loss today represents deferral, not a permanent escape.
When you rent out real estate, you report rental income and expenses on Schedule E of your tax return. This includes costs like repairs, maintenance, and depreciation. Depreciation allows you to deduct a portion of the property’s cost over its useful life, reducing your taxable income. The net gain or loss from Schedule E flows to your Form 1040, impacting your overall tax liability. By depreciating the property, you effectively lower your taxable income, which can be particularly beneficial if you’re in a high tax bracket. This strategy leverages the IRS’s allowance for wear and tear, aligning with IRC §167 and IRC §168. Be mindful of recapture rules under IRC §1250 if you sell the property.
You must use Schedule C to report depreciation on residential rental property if you primarily provide services for your tenant’s convenience, such as regular cleaning, changing linens, or maid service. This is because these activities classify the rental as a business, not passive income, according to IRS guidelines.
You must also file Form 4562 to report depreciation if you have placed property in service during the tax year.
