Investing in rental property can prove to be a smart financial move. For starters, a rental property can provide a steady source of income while you build equity and the property (ideally) appreciates. There are also tax benefits: You can deduct your rental expenses from any rental income you earn, thereby lowering your tax liability. Most rental property expenses – including mortgage insurance, property taxes, repair and maintenance expenses, home office expenses, insurance, professional services and travel expenses related to management  – are deducted in the year you spend the money. For additional details, see Tax Deductions For Rental Property Owners.

However, another key tax deduction – the one for depreciation – works differently. Depreciation is the process used to deduct the costs of buying and improving a rental property. (For a quick primer, check out An Introduction to Depreciation.) Rather than taking one large deduction in the year you purchase (or improve) the property, depreciation distributes the deduction across the useful life of the property. The IRS has very specific rules regarding depreciation, and if you own rental property, it’s important to understand how the process works.

Which Property is Depreciable?

According to the IRS, you can depreciate a rental property if it meets all of these requirements:

  • You own the property (you are considered the owner even if the property is subject to a debt).
  • You use the property in your business or as an income-producing activity.
  • The property has a determinable useful life (meaning it is something that wears out, decays, gets used up, becomes obsolete or loses its value from natural causes).
  • The property is expected to last more than one year.

Even if the property meets all the above requirements, it cannot be depreciated if it was placed in service and disposed of (or no longer used for business use) in the same year. Because land does not wear out, decay or get used up, it is not depreciable. And, in general, you cannot depreciate the costs of clearing, planting, and landscaping, since those activities are considered part of the cost of the land.

When Does Depreciation Begin and End?

You can begin taking depreciation deductions as soon as the property is “placed in service” or ready and available to use as a rental. Here’s an example: You purchase a rental property on May 15. After working on the house for several months, you have it ready to rent on July 15, so you begin to advertise online and in the local papers. You find a tenant, and his lease begins on September 1. Since the house was placed in service (that is, ready to be leased and occupied) on July 15, you would begin to depreciate the house in July (not in September, when you start to collect rent).

You continue depreciating the property until either:

  • You have deducted your entire cost or other basis in the property
  • Or you retire the property from service, even if you have not fully recovered its cost or other basis. A property is retired from service when it is no longer used as an income-producing property – or if you sell or exchange it, convert it to personal use, abandon it, or if it is destroyed.

You can continue to claim a deduction for depreciation for property that is temporarily “idle,” or not in use. If you make repairs after one tenant moves out, for example, you can still depreciate the property while you get it ready for the next tenant.

Depreciation Method

Three factors determine the amount of depreciation you can deduct each year: your basis in the property, the recovery period and the depreciation method used. Any residential rental property placed in service after 1986 is depreciated using the Modified Accelerated Cost Recovery System (MACRS), an accounting technique that spreads costs (and depreciation deductions) over 27.5 years, the amount of time the IRS considers to be the “useful life” of a rental property.

While it’s always recommended that you work with a qualified tax accountant when calculating depreciation, the basic steps are as follows:

  1. Determine the basis of the property. The basis of property is its cost, or the amount you paid (in cash, with a mortgage or in some other manner) to acquire the property. Some settlement fees and closing costs, including legal fees, recording fees, surveys, transfer taxes, title insurance and any amount the seller owes that you agree to pay (such as back taxes), are included in the basis. Some settlement fees and closing costs cannot be included in your basis, including fire insurance premiums, rent relating to occupancy of the property pre-closing and charges connected with getting (or refinancing) a loan: points, mortgage insurance premiums, credit report costs and appraisal fees.
  2. Separate the cost of land and buildings. Since you can only depreciate the cost of the building, and not the land, you must determine the value of each to depreciate the correct amount. To determine the value, you can use the fair market value of each at the time you purchased the property, or you can base the number on the assessed real estate tax values. Say you bought a house for $110,000. The most recent real estate tax assessment values the property at $90,000, of which $81,000 is for the house, and $9,000 is for the land. Therefore, you can allocate 90% ($81,000 ÷ $90,000) of the purchase price to the house, and 10% ($9,000 ÷ $90,000) of the purchase price to the land.
  3. Determine your basis in the house. Now that you know the basis of the property (house plus land) and the value of the house, you can determine your basis in the house. Using the above example, your basis in the house – the amount that can be depreciated – would be $99,000 (90% of $110,000). Your basis in the land would be $11,000 (10% of $110,000).
  4. Determine the adjusted basis, if necessary. You may have to make increases or decreases to your basis for certain events that happen between the time you buy the property and the time you have it ready for rental. Examples of increases to basis include the cost of any additions or improvements (that have a useful life of at least one year) made before you place the property in service, money you spent to restore damaged property, the cost of bringing utility services to the property and certain legal fees.

Examples of decreases to the basis include insurance payments you receive as the result of damage or theft, casualty loss not covered by your insurance for which you took a deduction and money you receive for granting an easement.

Which System to Use

The next steps involve determining which of two Modified Accelerated Cost Recovery System (MACRS) applies: the General Depreciation System (GDS) or the Alternative Depreciation System (ADS). GDS is the most common, and in general, you must use it unless you make an irrevocable election for ADS, or the law requires you to utilize ADS. ADS is mandated when the property:

  • Has a qualified business use 50% of the time or less
  • Has a tax-exempt use
  • Is financed by tax-exempt bonds
  • Is used primarily in farming

Once you know which MACRS system applies, you can determine the recovery period for the property. The recovery period using GDS is 27.5 years for residential rental property; if you are using ADS, the recovery period for the same type of property is 40 years.

Now, you need to determine the amount that can be depreciated each year. Since most residential rental property uses GDS, we’ll focus on that calculation.

For every full year a property is in service, you would depreciate an equal amount: 3.636% each year as long as you continue to depreciate the property. If the property was in service for less than one year (for example, you bought a house in May and began renting it in July), you would depreciate a smaller percentage that year, depending on when it was put in service. According to the IRS Residential Rental Property GDS table:

























For example, take a house that has a basis of $99,000 and that was put in service on July 15. For the first year, we would depreciate 1.667%, or $1,650 ($99,000 x 1.667%). For every year thereafter, we would depreciate at a rate of 3.636%, or $3,599.64, as long as the rental was in service for the entire year. Note that this figure is essentially equivalent to taking the basis and dividing by the 27.5 recovery period: $99,000 ÷ 27.5 = $3,600. The difference stems from the first year of partial service.

The Bottom Line

Depreciation can be a valuable tool if you invest in rental properties because it allows you to spread out the cost of buying the property over decades, thereby reducing each year’s tax obligation. Of course, if you depreciate a property and then sell it for more than its depreciated value, you will owe tax on that gain through the Depreciation Recapture Tax.

Because rental property tax laws are complicated and change periodically, it is recommended that you work with a qualified tax accountant when establishing, operating and selling your rental property business. This way, you can be sure to receive the most favorable tax treatment – and avoid any surprises at tax time.
