Idaho tax payment plan: the 12-month and 24-month options
Two income tax plans are offered by the Idaho State Tax Commission. No lien is filed under the special 12-month option, while the longer 24-month option may include one.
- Income plan without a lien
- A term of 12 months
- Longer term plan
- A term of 24 months
- Interest in the year 2026
- 6% per year
Two plan lengths and why a lien matters
Two main choices are available in Idaho and they are listed on the Tax Commission’s payment arrangements page. The special 12-month plan is available for income tax only. You pay off the debt within 12 months and the state files no lien. This plan is not available when a lien is already on file. Billing letters keep arriving while you make payments.
The 24-month option gives you twice as long to pay. In return, the state may require automatic bank withdrawals and may record a lien to protect its interest until your final payment is made. No action is taken on that lien as long as you stay in good standing. From time to time you may also get a request for updated financial details.
The lien option is worth weighing. Your credit is harmed by a Notice of Lien once it is filed and it may show up on your credit report for up to seven years, even after you pay, per the forced collection actions page.
Who qualifies?
Any Idaho plan requires that every other return and payment is up to date and that you promise to take on no new tax debts, per the Tax Commission rules. An income tax plan can be requested online. If a business owes sales tax, withholding tax or some other tax, it asks for a plan using the contact shown on its billing letter.
How do I set up a plan for paying Idaho income tax?
Have your bank routing and account numbers ready, since the application steps set up automatic payments. Pick the option that fits your situation:
- Take any letter from the last two years, then open tax.idaho.gov/payplan and enter the Letter ID found in the top right corner. That Letter ID starts with an L.
- If no recent letter is on hand, register for Taxpayer Access Point (TAP). Same-day access comes through a short quiz, once one of your last two returns has been processed. Otherwise, you get a registration code by mail and that takes about 10 working days.
- Start in TAP: click More and under Payment Plans choose Request a Payment Plan.
- For a joint return, use the information of the first person named.
- Your balance for the current tax year has to post first, so hold off until after May 5.
Interest and penalties do not stop
A payment plan leaves interest and penalties in place. Both 2026 and 2027 carry 6% a year, according to Idaho’s interest rate table. Under the penalty rules, income tax penalties run 0.5% each month and stop at 25% if you file on time and pay later. With no valid extension, the charge is 2% a month. Penalties start at $10.
What if my Idaho plan gets cancelled?
A plan can end if you miss a payment, pay late, do not answer a request for financial information or fall behind on new returns. After that, the Tax Commission turns to forced collection. Idaho Code section 63-3059 allows wages or bank accounts to be levied without going to court. The state may also seize property and sell it at auction.
Idaho and the IRS run separate plans. Every plan comes with its own date and rules, so pick a figure for each that still leaves money for rent, food and new taxes.
