ID Tax Extension

If you cannot file your return by the due date, Idaho allows you an automatic six-month extension of time to file. You do have to file a form to get an Idaho state tax extension. To qualify for the automatic extension, you must file your Idaho state tax return by October 15, 2015.

To avoid paying a penalty, the amount of tax withheld and other payments you have made must be at least 80% of your current year's tax liability or 100% of the total tax reported on your income tax return for the preceding tax year. File Form 51 with your payment. Even though an extension gives you additional time in which to file, the tax is due on the original due date of the return. You must pay interest on any tax not paid by the original due date of the return.

Tax brackets are adjusted annually based on the consumer price index.

ID Sales Tax:

Idaho imposes a sales tax of 6% on the sale, rental, or lease of tangible personal property and some services. For example, food is taxed, but prescription drugs are not.

Additional taxes apply to the sales of lodging at hotels, motels, and campgrounds.

Some ID resort cities, counties, and auditorium districts have a local option sales tax in addition to the state sales tax. 

Idaho also imposes a use tax of 6% on the consumption, use, or storage of goods in the state if sales tax wasn't paid on the purchase of the goods. This tax is paid directly to the state instead of the seller.

ID Personal Property Tax:

The Idaho State Tax Commission does not collect personal property tax. Personal property tax collections vary by county. If ID taxpayers participate in the Property Tax Deferral program, Property Tax Reduction program, or apply for a homeowner's exemption, they must be aware of the due dates for these programs. 

Idaho has a homeowner's exemption for primary dwellings, such as owner-occupied homes and manufactured homes. This exemption includes the value of your home and up to 1 acre of land. To qualify for the exemption, you must own and occupy your home before April 15. You must also file an application with your county assessor's office by April 15. Once your apply and qualify for the exemption, you do not have to reapply unless you move. The ID Tax Commission is required by law to recompute the homeowner's exemption each year. This is based on the federal Housing Price Index for the state. 

Participants in the Property Tax Deferral program must file an application with their county assessor's office by April 15 each year.

Participants in the Property Tax Reduction program (also known as "circuit breaker") must file an application their county assessor's office between January 1 and April 15 each year. This time frame applies even when they have not moved or changed ownership status. 

ID taxpayers should contact their county assessor for specific information about valuation. Regarding payments, they should contact the county treasurer. Some counties accept property tax payments online.

Odd Tax Fact:

Hotel/motel room occupants in the Greater Boise Auditorium District must pay a 5% sales tax. However, long-term residents who stay in their rooms for more than 30 days in a row are exempt from the tax.
