Apply for 2018 Property Tax Reduction/Deferral by April 17

(Boise, ID) – The Ada County Assessor’s Office is now accepting applications for enrollment in the 2018 State of Idaho Property Tax Reduction and Property Tax Deferral programs.  Residents are encouraged to submit applications as early as possible, but no later than the Tuesday, April 17, 2018 deadline.


Through the Property Tax Reduction Program, qualified property owners can reduce their annual property tax bill by up to $1,320.  The State of Idaho reimburses Ada County for the reduction in property taxes, up to the claimant’s qualifying benefit amount, on their home and up to one acre of land.  Eligibility for the Property Tax Reduction Program requires that a property owner be eligible for State of Idaho Homestead (Homeowner’s) Exemption, and that they meet one or more of the following qualifications as of January 1, 2018:

  • Age 65 or older
  • Widow/Widower of any age
  • Blind
  • Fatherless or motherless child under 18 years of age
  • Former prisoner of war/hostage
  • Disabled as recognized by the Social Security Administration, Railroad Retirement Board or Federal Civil Service, or Public Employee Retirement System
  • Veteran with a 10% or more service-connected disability or receiving a pension from Veteran’s Affairs (VA) for non-service-connected disability
  • Additionally, applicants must have a 2017 net income of $30,050 or less after deducting non-reimbursed medical expenses.  (Other deductions may include funeral expenses, business/farm losses, early banking withdrawal penalties and/or alimony paid.  Applicants must provide documentation proving their wages and all sources of income.)

The Ada County Assessor’s Office recently mailed Property Tax Reduction applications to residents who qualified for the program last year.  Residents who would like to apply, or who requested an application but have not yet received it, should contact the Assessor’s office at (208) 287-7200.


FREE Application Assistance IS AVAILABLE

There is no cost to apply for the 2018 Property Tax Reduction Program, and residents should not work with someone who tries to charge an application fee.  Residents who need one-on-one assistance to complete the application are encouraged to visit locations where Assessor’s Office employees will be offering assistance free of charge.  Please see the schedule on the next page for dates and locations.

Residents can also receive assistance at the Ada County Assessor’s Office, located at 190 E. Front Street, Suite 107, directly east of the Ada County Courthouse.  Applications for this program must be submitted by April 17, 2018.



The Property Tax Deferral Program offers residents a way to defer property taxes on their home and up to one acre of land.  These deferred taxes must eventually be repaid to the State of Idaho, with 6% interest.  To qualify, you must meet the eligibility requirements of the Property Tax Reduction (Circuit Breaker) Program and have a 2017 income of $43,636 or less.  The deferred property taxes and interest must be repaid when:

  • Any part of the property is sold or the title is transferred
  • The qualified claimant or the last qualified claimant dies
  • The property no longer qualifies for the Homestead Exemption (meaning it’s no longer the primary residence)
  • The Idaho State Tax Commission determines that the property tax deferral was granted to an individual who isn’t a qualified claimant or granted for property that does not qualify

Residents interested in applying for the 2018 Property Tax Deferral Program must submit an application with notarized signatures by April 17, 2018.


The 2018 Homestead (Homeowner’s) Exemption program exempts 50% of a property’s value, up to a maximum of $100,000 for the home and up to one acre of land.  To qualify, applicants must apply to the Ada County Assessor, indicating that the dwelling is owner-occupied prior to the April 15th occupancy deadline.  Applications must be postmarked or received in the office by April 17, 2018.  There are no income or age restrictions to qualify for this program, however, the exemption can only be claimed on a primary residence.

Property owners can apply for the Homestead/Homeowner’s Exemption online via the Ada County Assessor’s website at https://adacounty.id.gov/Assessor, or by contacting the Assessor’s Office at (208) 287-7200.

For more information about each of these programs, call (208) 287-7200, or visit the Ada County Assessor’s Office at 190 E. Front Street, Suite 107 – directly east of the Courthouse, on the ground floor of the Civic Plaza Apartment Complex.
