Idaho Income Taxes and ID State Tax Forms

efile Idaho tax return
Idaho
"The Gem State"

Idaho State Income Tax Return forms for Tax Year 2018 (Jan. 1 - Dec. 31, 2018) can be e-Filed in conjunction with an IRS Income Tax Return until October 15, 2019. In January 2020, you can e-File Tax Year 2019.

eFile.com makes it easy for you to e-file your IRS and Idaho State Tax Return (e.g resident, nonresident, or part-year resident returns). However, the IRS and the respective State Tax Agencies require you to e-file a Federal Income Tax Return at the same time you e-file a State Tax Return. This is not an eFile.com policy but an IRS and State Agency policy. Thus, technically you cannot e-File anywhere - not just eFile.com - a Idaho Tax Return without also e-filing the associated IRS Tax Return. But there is good news, please read on.

Detailed instructions on how you can only prepare and mail in - not eFile - a Idaho 2018 Tax Return - here via eFile.com. However, you must download/print and sign the forms and mail them to the Tax Agency.

* Due to IRS and State Tax Agency tax data sharing and validation requirements, you can only e-file a State Income Tax Return while also e-filing a Federal Income Tax Return. This is not an eFile.com created policy, but all online tax web sites have to adhere to this IRS/state issued tax data sharing policy. You can however prepare all 44 State Income Tax Returns on eFile.com if you have already e-Filed or filed your IRS return. Instructions on how you can ONLY prepare and file State Income Tax Return(s). Only on eFile.com can you prepare, file or e-file unlimited State Tax Returns for one low price and not pay for each State return like you would do on H&R Block® vs. TurboTax®. Dare to Compare Now.

Automatic Idaho 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, 2019.

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.

Idaho Tax Facts, Information

Idaho Tax Information and Contacts

ID Tax Type
Description

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.

Idaho 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.
