Amortization: The Other Slow Write-Off

Not everything spread over years is depreciation.

Depreciation applies to physical things. Amortization is the parallel rule for costs that are not physical: loan fees, points on a rental mortgage, certain lease and organization costs. They are deducted a little each year across the life of whatever they relate to — usually the loan term.

What to know

Loan costs follow the loan
Origination fees, appraisal charges tied to the loan, and points on a rental are spread over the years of the mortgage, not deducted at closing.
Payoff accelerates the rest
Refinance or sell, and the unamortized balance of the old loan's costs generally becomes deductible at that point.
Startup and organization costs
Forming an entity to hold property creates costs with their own limited immediate deduction and a long write-off for the remainder.
Keep the schedules separate
Loan amortization of a balance and tax amortization of a cost share a name and nothing else. Muddling them corrupts both records.

The tax benefit

Costs that produced no immediate deduction still turn into deductions eventually, and a refinance often releases the remainder all at once.

Worked example

Points across a loan

$4,500 of points on a 30-year rental mortgage gives $150 a year. Refinancing in year seven frees the remaining balance of about $3,450 as a deduction that year.

Watch out for

  • Points on a rental are not treated like points on your own home.
  • Fees paid to acquire the property belong in basis, not in loan amortization.
  • Refinancing with the same lender can complicate the write-off of the old costs.
