"The Gem State"

You can prepare and e-file your IRS and Idaho State Tax Return e.g resident, nonresident, or part-year resident returns now. Be aware that 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 an IRS and State Tax Agency policy, not an eFile.com policy. Thus, you technically cannot e-File anywhere - not just eFile.com - an 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 - an Idaho 2021 Tax Return - here via eFile.com. You can complete and sign the 2021 tax return forms online here on eFile, before you download, print and mail them to the state tax agency. The address is listed on the state tax form; find the the IRS mailing address here.

* 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.

Idaho Tax Extension

If you cannot file your return by the due date, Idaho allows you an six-month extension of time to file. You do have to file a form to get an Idaho state tax extension. To qualify for an extension, you must pay (at least) 80% of your estimated Idaho tax liability for the taxable year or 100% of your previous year’s "Total Tax" by the original deadline.

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 State Tax Payment Options
You can select one of these payment options either after you have e-filed or filed your 2021 Idaho Tax Return. Alternatively, you can pay Idaho income taxes here prior to filing (e.g in the case of an extension). Plus, you can make online Idaho tax estimate payments for next tax year. If you eFiled your taxes and pay online, you do not have to send in Idaho paper forms (e.g. payer tax return, extension form, or tax estimate form). 
Go to the Idaho State Tax Commission Site to submit your payment and select "Quick Pay" option.
Check the status of your direct payment
This is a free option if you want to pay your taxes owed via your bank account.
Use this payment option if you want to pay your tax payment via your credit or debit card. There is an additional service fee when you pay with your card.
Check or Money Order with Form ID-VP
Complete voucher Form ID-VP and attach it to your check or money order payable to "Idaho State Tax Commission". Mail them to the Form ID-VP address below.
Use this payment option if you wish to submit your payment via check or money order in the mail. 
Estimated Tax Payment Options
Choose one of these options: 1) Create an account or go to the Idaho State Tax Commission to submit your estimated payment (or if you already have an account, log into your account). 2) Pay via ACH credit by sending tax payments from your bank account to Idaho Tax's bank account. Contact your bank to make arrangements with them to credit the Idaho Tax's bank account with funds from your bank account. Your bank will inform you about the ACH services it offers and any related costs. 3) Pay via credit or debit card. Be aware that a service fee is added to each payment you submit with your card. 4) Complete voucher Form 51. Attach a check or money order for the tax period payable to "Idaho State Tax Commission". Write your Social Security numbers and the tax period on the check or money order. Mail the voucher and check/money order to the Form 51 address here.
Use one of these payment options if you want to submit estimated taxes rather than submit all your taxes owed at once. 
Many of these online IRS tax payment options can be used before or after you e-Filed your Income Taxes. You can pay tax extension and tax estimate payments. For estimate payments, you do not have to submit a form. Extension you can eFile on eFile.com for free.
These payment options are independent from you preparing and eFiling your tax returns on eFile.com. eFile.com offers these payment options for the convenience of all tax payers.
