Wyoming taxpayers who cannot pay their full state tax bill by the due date may qualify for a payment plan that lets them spread the assessed amount over time. Instead of paying one large bill, taxpayers can make manageable monthly payments to the Department of Revenue, helping keep their account current and avoiding additional penalties. This option can be beneficial when the total amount owed, including interest and penalties, places undue strain on personal or business finances.
Under an installment agreement, you will work directly with the Wyoming treasurer’s office or the county revenue office to determine a payment schedule that fits your budget. By filing all required returns and providing information on your income, expenses, and assets, you demonstrate your commitment to resolving your tax liability. While on a plan, you still accrue interest on the unpaid balance, but you may avoid more severe enforcement actions—such as liens on property or levies—so long as you make each payment by the due date.
This guide offers detailed information on eligibility requirements, application methods, and the documentation you must submit when contacting the revenue office. You will learn how to calculate an affordable monthly payment, review your options for modifying or canceling the plan, and understand what happens if you miss a payment. Note that procedures and rates are current as of March 2025, so always verify the latest details with the Wyoming Department of Revenue before taking action.
An installment agreement is a formal arrangement with the Wyoming Department of Revenue that allows taxpayers to pay state tax debts over time in fixed monthly installments rather than in one lump sum. This agreement outlines the total balance owed, the monthly payment amount, and the plan's duration.
The Wyoming Department of Revenue recognizes that taxpayers may experience temporary financial hardships that make it difficult to pay tax bills immediately. The department promotes voluntary compliance, which is achieved by offering payment plans that help taxpayers avoid extreme enforcement actions.
Entering into a payment plan demonstrates your commitment to resolving tax debts, which generally prevents the department from filing liens or levies while you comply.
An installment agreement breaks down your total tax liability into smaller, consistent payments, making it easier to budget and plan.
Occasionally, the department may waive or credit interest and penalties for reasonable cause once you establish and maintain a payment plan.
You must have submitted all past-due Wyoming tax returns before requesting an installment agreement.
You must demonstrate that you cannot immediately pay the full tax liability without causing undue hardship.
You must make consistent, on-time payments according to the agreed schedule.
Higher balances may require more documentation or shorter repayment terms to ensure timely resolution.
Your timely filings and payment records will influence the department’s willingness to grant favorable terms.
Business-related taxes (e.g., sales or use tax) often involve trust funds collected from customers, which may trigger stricter requirements.
Compile income records, expense statements, asset and liability summaries, bank statements, and proof of other debts.
Estimate how much you can pay each month without creating undue hardship.
Ensure all required returns are filed and updated before requesting a plan.
Call (307) 777-5200 to discuss your situation and request a payment plan.
This method is best for simple cases or when you need immediate guidance.

This approach suits complex situations or when you must submit supporting documentation.
Your name, address, Social Security or FEIN, and daytime phone number.
Specify whether the debt is for individual income tax, sales tax, use tax, or other obligations.
Outline how much you plan to pay monthly and why that amount is reasonable based on your finances.
Provide documentation like pay stubs, bank statements, expense logs, and asset summaries.
This option is best for taxpayers who can pay off their debts quickly and have smaller amounts owed. If you pay off your Wyoming tax bill in six months, you can avoid making payments for a long time and lower the total interest charged. Choosing a short-term schedule speeds up getting complete control of your account back and reduces the total cost.
Manageable monthly payments over a standard repayment duration balance moderate interest costs. You can budget better if you spread your Wyoming tax bill over six to twenty-four months. This way, you don't have to pay the higher interest rates with longer plans. Most taxpayers who need more than six months but want to keep their extra interest costs low can use this middle-ground approach.
If you have a lot of trouble with money or owe many taxes, you can set up a longer payment plan. If you extend the term beyond two years, the monthly payment will be lower, but the total interest you will pay over the life of the agreement will be higher. To be eligible for more extended periods, you may need to give more paperwork, like detailed records of your income and expenses.
Wyoming Statute § 39-15-108 says that the annual interest rate on unpaid state taxes is the average prime rate set by the state treasurer each fiscal year, plus four percent. This method ensures that rates align with what is happening in the market and gives taxpayers a clear picture of what to expect. The treasurer's office publishes the updated prime rate annually, usually in March. This means that the interest rate on your plan may change a little from year to year.
Wyoming’s interest rate equals the state treasurer’s average prime rate for the previous fiscal year plus 4%, aligning tax debt costs with broader lending trends.
Interest begins accruing on each tax liability starting on the original due date and continues until the full balance is paid, so earlier payments reduce overall interest.
Although rates vary, state law caps interest at 18% annually to protect taxpayers from excessively high charges.
If the underpayment stems from disobeying rules without intending to defraud, the penalty is 10% of the deficiency.
25% of the deficiency applies when the underpayment is due to fraud, intending to evade taxes.
$10 if filed within 30 days of notice; $25 if filed after 30 days.
The department may waive or credit interest and penalties for reasonable cause under § 39-15-108(b)(iii)–(c)(xv).

Include your name, tax ID, and tax type on the payment.
Pay at the Cheyenne office during business hours.
Set up calendar alerts or automatic payments through the treasurer’s office portal to stay current on your Wyoming tax payment plan. By scheduling notifications for each payment due date, you ensure you never miss a payment and avoid additional interest or penalties. This proactive approach helps you manage your account balance and maintain good standing with the revenue office.
Keep detailed records of every payment you make, including receipts, confirmation numbers, and bank statements. Filing these documents in a dedicated folder or digital system makes it easy to verify amounts paid and address any questions from the county or state office. Maintaining accurate records also aids in monitoring your interest assessments and streamlines subsequent interactions with the Department of Revenue.
Make extra payments against your Wyoming tax debt whenever possible to reduce the total interest you pay. Even small additional amounts lower your principal balance, shorten the repayment timeline, and free up cash flow sooner. If your financial situation improves, contact the revenue office for an updated payoff statement and consider paying off the remaining bill early to save on assessed interest.
If you miss a scheduled payment on your Wyoming tax payment plan, you must contact the Department of Revenue immediately. Explaining your situation and submitting the missed amount promptly helps prevent additional assessed interest and maintains your good standing with the treasurer’s office.
After making the late payment, continue filing all required returns and paying any new tax liabilities on time. Demonstrating ongoing compliance ensures your installment agreement remains eligible and protects you from enforcement actions on your account.
Missing two or more consecutive monthly payments signals noncompliance. Repeated delinquencies may lead the revenue office to default your plan, restoring the full balance—and any accrued interest—due immediately.
Even if you keep up with payments, you must still file all Wyoming tax returns by their due dates. Failing to file new returns can trigger a default and expose you to additional penalties on top of your existing balance.
Misrepresenting income, expenses, or assets when applying for your installment arrangement may cancel the plan. The Department of Revenue may assess extra penalties or interest if you provided inaccurate data.
When a payment plan defaults, the Wyoming Department of Revenue may file a lien on your property to secure the unpaid tax amount, interest, and penalties under § 39-15-108(d). A lien notifies creditors and can affect your credit, so maintaining current payments on your installment agreement helps you avoid this enforcement action.
With board approval, the state may seize and sell real or personal property to satisfy your outstanding tax debt (§ 39-15-108(e)). This action can include vehicles, equipment, or other assets you own. Staying in good standing with the treasurer’s office and making timely payments prevents property seizure and protects your assets.
If other actions fail, Wyoming’s Department of Revenue can initiate judicial collection proceedings, adding court costs, legal fees, and additional penalties to your bill. These proceedings can further damage your credit and prolong resolution, so keeping your tax payment plan current is critical to avoid litigation.
When you recognize a missed payment or default, contact the Wyoming Department of Revenue to discuss reinstating your installment agreement. Prompt communication shows your intent to resolve the bill and helps prevent further enforcement actions by the county or state office.
To reinstate your plan, you must pay all missed amounts—including assessed interest and penalties—plus any new tax liabilities accrued. Once your account balance is current, you regain eligibility for the plan and can resume regular monthly payments.
You must file any overdue Wyoming tax returns before the department will reinstate your agreement. Submitting all required returns ensures the revenue office has complete information on the total amount owed and demonstrates your commitment to compliance.
You may request modified payment options or adjusted schedules if your financial situation changes. When you contact the treasurer’s office, provide updated income and expense documentation. Approval is at the department’s discretion, so clear communication and complete information improve your chances of obtaining favorable terms.
You may need to adjust your Wyoming tax payment plan if your income, expenses, or ability to pay changes significantly. Contact the treasurer’s office as soon as possible to discuss your situation and remain eligible for flexible payment options. Making timely requests ensures you avoid default triggers and keep your account current.
Call the Wyoming Department of Revenue at (307) 777-5200 to request a modification and provide updated financial documentation, such as recent pay stubs, bank statements, or expense records. This information helps the revenue office assess an appropriate monthly payment amount and avoid additional interest or penalties. Be prepared to file any missing tax returns before your amendment is reviewed.
You must continue paying under your existing installment agreement until the department approves your changes. Continuing on-time payments prevents new assessed interest and protects your credit. Maintaining compliance during the review period shows good faith and increases the likelihood of a favorable adjustment.
If you can now pay the remaining balance on your Wyoming tax bill, request a payoff statement listing all taxes, accrued interest, and any penalties. Paying in full allows you to cancel the installment agreement and avoid further interest charges. Contact the county or state revenue office to confirm the final amount and acceptable payment methods.
After submitting your final payment, ask the Department of Revenue for written documentation showing your tax debt is satisfied. Receiving formal confirmation protects you if any future questions arise about your account. Keep this statement with your tax records to verify that no balance remains.
Paying off your plan early can save you money by reducing the interest assessed over time. Contact the treasurer’s office in March or whenever you’re ready to receive an updated payoff amount, then submit the full payment. Early payoff frees you from monthly obligations and helps you regain control of your financial situation sooner.
Generally, once you set up a tax payment plan with the Wyoming Department of Revenue, collections like liens or levies are paused as long as your account remains current. Any lien assessed before your installment agreement may still stand until you pay the full amount owed. You must make each monthly payment on time to maintain eligibility for this option.
Enrolling in a state tax payment plan does not directly appear on credit reports. However, if the Department of Revenue files a tax lien against your property for unpaid taxes, that lien may show as a public record and hurt your credit. Staying compliant by filing returns and making timely payments helps protect your credit and avoids negative entries.
Wyoming allows consolidation of back tax amounts from multiple years and various tax types—such as income, sales, or use taxes—into one installment agreement. This streamlined option simplifies your repayment schedule and helps you track your total debt. When you contact the treasurer’s office, provide clear information on each tax year and type you wish to include.
If you have an active Wyoming payment plan, the Department of Revenue may apply any state tax refund you receive directly to your outstanding balance. This offset reduces your remaining liability and shortens the repayment timeline. If your refund exceeds the balance, the county treasurer’s office will issue you a check for the surplus once your account shows a zero balance.
Yes, you can pay off your Wyoming state tax payment plan early without incurring additional penalties. Early payoff reduces the total interest you owe. Contact the Department of Revenue to request a current payoff statement listing your remaining tax, assessed interest, and any applicable fees. Then submit the full payment according to their instructions.
Yes, the IRS and the Wyoming Department of Revenue are separate authorities, so you must establish individual payment plans for federal and state taxes. When you contact the state office, share information about your IRS agreement to provide context, but follow Wyoming’s procedures and deadlines to keep both accounts in good standing.
Approval time for a payment plan depends on your financial details and the department’s workload. Simple cases may receive same-day approval if you file all returns and provide payment options immediately. More complex requests—especially those requiring detailed income and expense documentation—can take two to four weeks. Submitting complete, accurate information helps speed up the process.
