Idaho Sales Tax Nonpayment Risk Checklist
Introduction
Sales tax nonpayment in Idaho occurs when a registered seller fails to submit collected sales tax to the state by the deadline. This differs from owing sales tax for the first time—it means sales tax was already collected from customers but not turned over to Idaho.
The state treats nonpayment seriously because the money collected belongs to the state, not the business. Knowing what nonpayment looks like, how the state reacts, and what options are available can help lower penalties, interest, and enforcement actions. Ignoring nonpayment typically triggers escalating collection efforts, including notices, penalties, liens, and possible legal action.
Taking action early—even if payment cannot happen immediately—creates a clearer path forward than waiting for the state to contact the business. This checklist explains what nonpayment means, what usually happens next, and the step-by-step process for addressing it.
What This Issue Means
Sales tax nonpayment means that sales tax collected from customers in Idaho was not sent to the Idaho State Tax Commission by the required deadline. This typically appears as a missed return filing deadline or a failure to pay tax shown on a filed return.
Nonpayment can occur due to cash flow problems, administrative oversight, or intentional non-compliance. The state views all nonpayment the same way as a return of outstanding debt that must be collected.
Why the State Issued This or Requires This
Idaho requires sales tax to be collected and remitted because it is held in trust by the seller on behalf of the state. When a seller collects tax from a customer, that money is not the seller’s income—it belongs to Idaho. The state has a legal duty to collect unpaid sales tax to fund state services.
Nonpayment is flagged through routine filing reviews, account monitoring, or when a seller fails to submit a return altogether. The state’s collection process begins with notices and escalates if the debt remains unpaid.
What Happens If This Is Ignored
Ignoring nonpayment typically leads to additional notices from the Idaho State Tax Commission, including warning letters and formal demand notices. The state assesses penalties and interest on unpaid amounts. Interest accrues on unpaid balances, and the specific interest rate should be confirmed with the Idaho State Tax Commission.
If payment is not made after notices, the state can file a Notice of Lien at the Idaho Secretary of
State’s office, which becomes a public record. A lien is valid for five years unless a continuation is filed before it expires, extending it another five years.
The Idaho State Tax Commission can serve a Notice of Levy on bank accounts, wages, and other property. Under Idaho Code section 63-3059, the Tax Commission does not need court authorization to take levy action.
The Idaho State Tax Commission can collect taxes by levy or court action within six years from the date of assessment, with assessment generally occurring within three years from the return due date or filing date. The longer nonpayment continues, the more the total owed increases due to accumulating interest and penalties.
What This Does Not Mean
Nonpayment does not automatically mean the business license has been revoked or that a criminal case has been filed. It does not mean the state has seized assets or filed a court judgment yet.
Nonpayment also does not mean all collection options have been exhausted—the state typically exhausts administrative remedies before pursuing legal action. Nonpayment of sales tax is not the same as owing personal income tax or other state taxes; each tax type is tracked and handled separately.
Checklist: What to Do After Identifying Sales Tax
Nonpayment
Step 1: Locate Any Notices
Check mail, email, and any business account documents for notices from the Idaho State Tax
Commission. Write down the notice dates, the tax periods listed, and the amounts stated. Keep these documents in one place for reference.
Step 2: Verify Tax Periods Involved
Review records to confirm which months or quarters the nonpayment covers. Compare filed returns to the amounts stated in the notice. If returns were not filed for certain periods, note those periods separately.
Step 3: Determine Filing Status
If returns were filed but payment was not made, the issue is payment only. If returns were not filed, the issue is both filing and payment. This affects which documents are needed and the steps that follow.
Step 4: Calculate Current Total Owed
Gather the base tax amount from the notice. Note any penalties and interest listed. Understand that interest continues to accrue until paid in full. If no notice was received, contact the Idaho
State Tax Commission at (208) 334-7660 or (800) 972-7660 to request a statement of account.
Step 5: Contact the Idaho State Tax Commission
Call (208) 334-7660 in the Boise area or (800) 972-7660 toll-free. Ask to speak with a collection or compliance representative. Provide the business name, account number, and the tax periods in question. Request a current account statement showing exact amounts due. You should receive a response within five to seven business days for general inquiries.
Step 6: Ask About Payment Options
Request payment arrangements through the TAP system at tax.idaho.gov or by phone. Ask what documentation is required to set up a payment plan. Understand the terms—payment plans require regular payments and remain in effect until the full balance is paid.
Step 7: Discuss Voluntary Disclosure if Applicable
Some situations allow a taxpayer to voluntarily come into compliance by filing missing returns and paying past-due amounts. The state will explain whether this option applies to the specific situation. This step is important to take before the state initiates enforcement action.
Step 8: Gather Documentation
Prepare recent bank statements, profit and loss statements, or cash flow projections if a payment plan will be discussed. Have information about business income and expenses available. The state may request financial information to assess the ability to pay.
Step 9: Address Current Filing Requirements
Contact the state at (208) 334-7660 or (800) 972-7660 before filing new quarterly or annual returns to clarify the process. Filing new returns without resolving past nonpayment can complicate account management.
Step 10: Document All Communication
Write down dates, times, names of staff members, and a summary of what was discussed. Keep copies of all written correspondence, notices, and agreements. Maintain records of any payments made and confirmation of receipt.
Step 11: Follow Payment Plan Terms
Make payments through the TAP system at tax.idaho.gov, by phone at (208) 334-7660, or by mail at (800) 972-7660. Accepted payment methods include cash, checks, e-checks, money orders, and credit cards. Make payments on time and in the amount specified. Missing a payment plan installment typically results in the plan being canceled and the case being escalated to collection action.

Step 12: Request Written Confirmation
Once the account is paid in full, ask the state to issue a letter confirming that all outstanding liability has been satisfied. When the debt is paid in full, the Idaho State Tax Commission records a Release of State Lien at the Idaho Secretary of State’s office if a lien was filed. Keep this confirmation indefinitely.
What Happens After This Is Completed
Once you initiate communication with the state and identify a path forward, the state typically suspends collection actions while the arrangements remain active. If a payment plan is established, the state expects regular payments in accordance with the schedule.
If immediate payment brings the account current, the state closes the collection file and restores the account to its normal status. The stain is assessed in accordance with the law; these are typically included in the total amount owed calculated by the state.
Common Mistakes to Avoid
Failure to meet state communication deadlines often results in enforcement action, including liens or levies. Respond to all state notices within the timeframe specified. The state typically sends multiple notices before escalating to enforcement.
Treating each notice as necessary and responding reduces the risk of surprise enforcement action. Sending a partial payment without contacting the state at (208) 334-7660 or (800)
972-7660 first can create confusion and may not reduce the immediate enforcement risk. Filing current-period returns while past-due amounts exist can cause new filings to be held or applied to past-due balances unexpectedly.
Clarify the account status through the TAP system at tax.idaho.gov or by phone before filing new returns. Without documentation of payments, agreements, and communications, disputes can arise over what was paid or promised. Keep all records indefinitely.
The Idaho State Tax Commission can collect taxes within 6 years from the assessment, and nonpayment does not go away. If the information is incomplete or inaccurate, the state may have difficulty locating the account or making arrangements. Provide the business name, tax ID, and start and end dates clearly.
Frequently Asked Questions
How long does the state have to collect unpaid sales tax?
Under Idaho law, the Idaho State Tax Commission may pursue collection of unpaid sales tax and related tax debt through levy or court action within six years from the date the tax is assessed. In most cases, assessment must occur within three years from the tax return due date or the date the tax filings were submitted, whichever is later. These rules apply to retailers selling taxable products and tangible personal property under Idaho sales and use tax statutes.
How much interest and penalties will be added to the unpaid amount?
Interest accrues on unpaid sales tax balances from the original due date until the balance is paid in full. Civil penalties may also apply, including failure to pay penalties, depending on the type of violation, such as late payment, failure to file required returns, or failure to remit collected tax. The applicable interest rate and penalty amounts are set by state law and reflected on your official statement of account. Contact the Idaho State Tax Commission at (208) 334-7660 or
(800) 972-7660 for current figures and instructions specific to your account.
Can penalties be reduced or eliminated?
The Idaho State Tax Commission may grant penalty abatement when a taxpayer demonstrates reasonable cause, such as circumstances beyond their control. In addition, Idaho law allows offers in compromise under Idaho Code section 63-3048, which may reduce tax, penalties, or interest based on disputed liability, doubt as to collectibility, economic hardship, or effective tax administration. Requests are evaluated individually, and approval is not guaranteed. Taxpayers may wish to consult qualified tax professionals or lawyers for assistance with complex penalty relief requests.
What if I disagree with the amount the state says is owed?
If you receive a Notice of Deficiency Determination, you generally have 63 days from the mailing date to file a written protest with the Idaho State Tax Commission. The protest must include identifying information, the tax period involved, the specific item disputed, and the factual or legal basis for the objection. This process applies to disputes involving tax filings, assessed tax debt, penalties, or credits. The Commission can provide instructions on how to submit a valid protest.
Will the state accept a payment plan?
The Idaho State Tax Commission has the authority to establish payment plans for unpaid sales tax and related liabilities. Whether a payment arrangement is approved depends on the total amount owed, prior compliance history, and current financial circumstances. Payment plans do not eliminate interest but may prevent further enforcement action if maintained. Requests can be made through the TAP system at tax.idaho.gov or by contacting the Commission directly.
How do I know if my account has been referred for enforcement action?
You can confirm your account status by contacting the Idaho State Tax Commission at (208)
334-7660 or (800) 972-7660 or by reviewing your account online through the TAP system. A current statement of account will show whether the balance is still in routine collections or has progressed to enforcement. Enforcement status may affect retailers' permits, eligibility for refunds, and the state’s ability to pursue collection actions independent of federal taxes.
Closing
Sales tax nonpayment creates ongoing tax liabilities under Idaho Tax Law and places an account under active tax compliance review. If sales tax returns, use tax, or other necessary tax forms are not paid or submitted, the Idaho State Tax Commission can determine how much tax you owe, apply the correct tax rate, and take steps to collect the money according to state tax rules.
The most effective way to address failure to file or unpaid business tax obligations is to act promptly. By reviewing each tax return, correcting unfiled returns, and confirming tax payment amounts through official tax forms or tax and accounting records, you preserve your rights and reduce enforcement risk. Payment plans and other Tax Relief options may be available through the TAP system at tax.idaho.gov, depending on compliance history.
Maintaining accurate registration, exemption documentation, and transaction records supports proper reporting and audit review. Contact the Idaho State Tax Commission at (208) 334-7660 or (800) 972-7660, respond to notices, and follow agreements to resolve tax audits, prevent bank levies, and minimize disruptions due to Idaho revenue legislation.
