Depreciation refers to the value of property that’s lost over time due to wear, tear, and obsolescence. In the case of improvements to a rental home, you can deduct a portion of that lost value every year over a set number of years. Carpeting and appliances in a rental home, for example, are usually depreciated over five years.
You can begin depreciating the value of the entire rental property as soon as the rental home is ready for tenants and you hold it out for rent, even if you don’t yet have any tenants. In general, you depreciate the value of the home itself (but not the portion of the cost attributable to land) over 27.5 years. You’ll have to stop depreciating once you recover your cost or you stop renting out the home, whichever comes first. Depreciation is a valuable tax break, but the calculations can be tricky and the exceptions many. Read IRS Publication 946, “How to Depreciate Property,” for additional information, and use Form 4562 come tax time. You may need to consult a tax adviser. (HOuselogic)
