Dealing with tax debt in Washington State can be overwhelming, especially when penalties and interest begin to add up. For individuals and small businesses unable to fully resolve their state tax liability, settling for less than the total owed might sound appealing. While many people are familiar with the IRS’s Offer in Compromise program for federal taxes, Washington State has its version: the Washington Offer in Compromise, also known as a Rule 100 Settlement.
Offered through the Washington State Department of Revenue, this compromise program allows eligible taxpayers to settle their disputes under specific circumstances. However, Washington’s approach differs significantly from the federal model. The state does not consider financial hardship a valid reason to reduce debt. Instead, it focuses on resolving disputes where the law is unclear, the situation is unlikely to happen again, or a strict interpretation of the law would lead to unusually harsh results.
This guide is designed to help you understand Washington’s Rule 100 process, determine whether your situation might qualify, and walk you through how to submit a written settlement offer to the state. Whether you're facing a legal dispute over tax rules or trying to prevent an unfair outcome, understanding your options under this program is the first step toward resolution.
The Washington Offer in Compromise program, formally known as a Rule 100 Settlement, allows qualifying taxpayers to settle certain tax disputes with the Washington State Department of Revenue for less than the full amount assessed. This is not a relief program for those who simply can’t afford to pay. Instead, it’s designed to resolve tax issues based on specific legal or administrative concerns.
Washington’s compromise program is grounded in Washington Administrative Code (WAC) 458-20-100. It provides a legal pathway to resolve disputes under certain circumstances—typically when there’s a legitimate disagreement over how the tax law applies or when strict law enforcement would result in an unfair or overly punitive outcome.
Rather than evaluating your ability to pay, the Department focuses on the nature of the dispute. For example, your case might qualify if the law changed and your tax issue is unlikely to recur, or if you received unclear or conflicting written instructions from the Department. The Department aims to resolve situations that appear debatable, factually complex, or unjust, adhering strictly to the letter of the law.
Once an offer is submitted, the Department’s Administrative Review and Hearings Division will evaluate it. The Department may sign a formal agreement to settle the dispute for a lower sum if it qualifies. But unlike many federal or financial hardship programs, such an arrangement is not a negotiation about what you can afford—it’s about whether your case meets the legal criteria for compromise.
Although the IRS and Washington State offer a compromise, the two programs serve different purposes and follow very different rules.
The IRS program is based primarily on taxpayers' inability to pay their full tax liability. It considers your income, assets, and necessary living expenses. If paying your debt creates significant financial hardship, the IRS may accept a lower amount.
Applicants must fill out detailed financial forms (like Form 433-A or 433-B), pay a $205 application fee, and often submit part of the proposed payment along with the application. The IRS evaluates whether the government will likely collect more by compromising or continuing to pursue full payment.
By contrast, the Washington State Department of Revenue does not evaluate whether you can afford to pay. Financial hardship alone is not a valid reason to settle. Instead, Washington’s compromise program looks at four specific types of situations:
Washington uses Form 50-0006, and while there’s no application fee or automatic need for financial disclosure, the Department expects a clear, well-supported legal basis for the offer.
One of the most common mistakes taxpayers make is applying Washington’s program with arguments about income or expenses. If you're struggling to afford your taxes, the better route is to request a payment plan through the Department’s Compliance Division.
In summary, the IRS offers an offer in compromise to evaluate whether you can pay. The Washington version evaluates whether a fair legal outcome is possible under unique or complex circumstances.
The Washington Offer in Compromise, or Rule 100 Settlement, is only available to taxpayers who meet specific legal or administrative criteria. Unlike federal programs that allow financial hardship as a qualifying factor, Washington’s program is not designed to address an inability to pay.
To be considered eligible, your case must meet at least one of the following standards:
These reasons are based on legal merit, not your ability to pay. Your offer must explain why your situation meets one or more of these circumstances.
The Department of Revenue will not consider a Rule 100 Settlement in the following situations:
If you're unsure whether your case qualifies, reviewing WAC 458-20-100 or consulting a tax professional can help clarify your position. Ultimately, the focus is on resolving legal disputes, not waiving taxes because they’re unaffordable.
If you believe your situation meets the legal criteria, the next step is to prepare and submit a written settlement offer to the Washington State Department of Revenue. This process is handled through the Administrative Review and Hearings Division, which evaluates whether your case qualifies for settlement under Rule 100.
Before you begin, revisit the four acceptable settlement criteria. Your request must be based on one or more of the following:
If your case is purely based on inability to pay, you’ll need to explore payment plan options instead.
You can use the Department’s official Form 50-0006 or prepare your written document. Regardless of the format, your offer must include:
If you’re working with a tax professional, ensure the Department has a Confidential Tax Information Authorization (CTIA) on file so they can speak with your representative.
There are three ways to send your offer to the Administrative Review and Hearings Division:
Keep copies of everything you send, including the offer, supporting documentation, and any confirmation.
Once your offer is received, the Department will acknowledge and review it. Your case may be referred to the settlement track, a special internal process designed to evaluate settlement offers more closely. If your offer qualifies for this track, a tax review officer will contact you to discuss it further. The department will let you know if it doesn't qualify and continue processing the case through the standard appeal or review channels.
It’s important to stay current on all ongoing tax obligations while your offer is under review. Failing to file or pay future taxes can negatively affect its evaluation.
The Department may also request additional information during the process. Responding wholly and quickly will help keep things moving.
Submitting a firm settlement offer is more than just filling out a form. To increase your chances of success, your submission must be detailed, well-organized, and directly aligned with the Department’s expectations under Rule 100.
While you can draft your written settlement offer, the Department of Revenue provides Form 50-0006, which is specifically designed for this process. It guarantees the inclusion and presentation of all necessary information. This form asks for basic information like taxpayer and representative details, the nature of the dispute, and your proposed settlement terms. Regardless of your format, the goal is to explain why your case qualifies under certain circumstances outlined in WAC 458-20-100.
Your settlement offer should address the following points:
Avoid vague or emotional arguments. The Department is not evaluating your hardship or financial stress—it’s considering legal merit and fairness under the law.
There’s no strict list of required documentation, but offering strong evidence can make a significant difference. Examples of helpful attachments include:
Be concise but thorough. The Department will likely consider your offer when you provide a clear and well-supported case.
Once received, your offer will be entered into the review process. Both parties will sign a closing agreement and settle the case if accepted. If rejected, you can continue with the standard appeal process—but you won’t be able to submit a new settlement offer for the same issue unless circumstances change.
If your situation doesn’t meet the criteria for a Rule 100 Settlement, you still have options for managing your tax debt. The Washington State Department of Revenue offers several alternative solutions—especially for those experiencing financial hardship.
For taxpayers who cannot pay their full taxes immediately, the Department offers a self-service payment plan. These plans allow you to pay off your debt over 3, 6, 9, or 12 months, depending on the total amount and your eligibility. To qualify, you must comply with your filing obligations, and you’ll need to set up the plan through the Department’s online portal. Once approved, collection actions on that portion of your debt are suspended if you follow the plan's terms.
You may benefit from working directly with the Department's Compliance Division if your situation is more complex—such as ongoing hardship, illness, or unexpected financial setbacks. They can assist with longer-term payment arrangements or help you avoid specific penalties.
While pursuing relief, it’s essential to remain current on all future tax filings and payments. Failing to do so may trigger penalties, jeopardize existing arrangements, and limit your options for resolving your debt. Even if you don’t qualify for a settlement, proactively addressing your tax obligations can protect you from additional fees and preserve future eligibility for other forms of assistance.
Working with a tax professional can make a meaningful difference when applying for a Rule 100 Settlement. While individuals can submit an offer independently, a tax representative can help clarify your legal arguments, organize your documentation, and ensure the offer is aligned with Department expectations.
This assistance is particularly valuable for businesses with complex records or multiple years of disputed tax assessments. A professional can review prior communications, identify which criteria apply to your case, and help build a persuasive narrative around those facts. It can be difficult for taxpayers to understand how the state evaluates settlement offers. A qualified advisor can help you determine whether your situation meets the required legal standards—not just whether you disagree with the tax bill. They can also help you respond if the Department requests additional information during the review.
Before the Department can discuss your account with a representative, you must file a Confidential Tax Information Authorization (CTIA) form. This allows your preparer to speak with the department on your behalf and receive updates on the status of the offer. While there’s no guarantee that your offer will be accepted, submitting a well-argued and well-documented case with the support of a knowledgeable professional can improve your chances.
Washington’s Rule 100 Settlement program offers a unique path for taxpayers facing legal or administrative tax issues. If your case involves unclear law, outdated guidance, or unusual circumstances, it may be worth pursuing a settlement through this process.
That said, it’s not the right option for everyone. If your only concern is an inability to pay, you won’t qualify. But if you're in a legal gray area or dealing with a one-time issue unlikely to recur, a review by the Administrative Hearings Division could lead to a fair resolution.
While submitting a firm and well-supported offer does not ensure a favorable outcome, it can facilitate negotiation and potentially lead to relief. The Department will make a final decision after considering whether your offer meets the program’s standards and whether it reasonably addresses the underlying dispute.
If successful, you can settle your tax obligation for less than the full amount and resolve your dispute without going through a lengthy appeal or court process. As always, staying current on all ongoing tax obligations and responding to requests from the Department can improve the likelihood of a successful outcome.
No, the Department of Revenue does not accept offers based solely on tax debt or inability to pay. If you cannot pay what you owe, your best option is to contact the Compliance Division to request a payment plan. The Rule 100 Settlement program is intended for legal or administrative disputes, not relief of financial hardship.
The settlement track is an internal review process the Department of Revenue uses to evaluate Rule 100 offers. If your case is referred to this track, a tax review officer will reach out to discuss the offer. Your dispute continues through the standard administrative review process without settlement consideration if it's not referred.
No, the Washington State Department evaluates tax liability disputes based on whether they involve non-recurring issues, harsh outcomes, or unclear law. Your dispute won't qualify for settlement if it doesn’t meet those standards. Routine objections or disagreements over what you owe are generally insufficient to be considered for compromise.
No, if you are in an open bankruptcy proceeding, you are not eligible for the Washington Offer in Compromise. Before considering any settlement offer, including Rule 100, the Department of Revenue requires the resolution of all bankruptcy matters. You may still have options through bankruptcy court or after discharge.
Yes, if your offer is accepted, you must follow the terms of the closing agreement, which may include making payments on the agreed-upon amount. The Department of Revenue will consider the case resolved only after completing the payments as outlined. Failing to meet the terms can void the agreement.
