What is amortization and how does it work?
Many taxpayers are familiar with depreciation, which means deducting an asset's value over time, but fewer are familiar with depreciation’s cousin, amortization.
Amortization works like depreciation for intangible (non-physical) assets, like refinance expenses, goodwill, patents, and copyrights.
Unlike depreciation, there are no accelerated or bonus options. Amortized assets are deducted evenly across their useful life using the straight-line method.
Amortization commonly happens when you refinance your home and pay points, own a small business, or rent a property.
Refinancing
The IRS lets you deduct points evenly over the life of the loan. Under certain circumstances you can deduct points in the year paid. When refinancing a mortgage, points are generally deducted over the life of the new loan.
Here’s how to deduct points paid with a refinancing:
After you have entered your Form 1098, TurboTax will ask: Did you pay points in [year] when you took out the loan?
Select I paid points when I refinanced, purchased a second home, or opened a home equity loan in [year].
On the Tell us about the points you paid screen, enter your points and the correct information about your loan.
After you answer the remaining questions, TurboTax will report your deductible points on Schedule A, Line 8c.
