How to catch up on multiple years of unfiled taxes across different states?

Insogna Blog 5 2

Realizing you are behind on multiple years of tax filings can feel overwhelming, but creating a systematic plan can help you regain control and confidence in fixing it. Whether you moved frequently, ran a multi-state business, or got overwhelmed, the first step to freedom is admitting there is a problem and taking organized action. The good news is that both the IRS and state authorities generally prefer that you come to them voluntarily rather than waiting to be found, which often leads to more favorable outcomes and lower penalties.


Are you feeling overwhelmed by your tax history and hoping for a fresh start? We understand how challenging that can be. Reach out to us and let’s schedule a strategy session.

How to catch up on multiple years of unfiled taxes across different states?

Step 1: Conducting a Multi-State Nexus Study

Before you start filing back returns, you must determine exactly where you were legally required to file. For example, if you ran a multi-state business with sales in [State A] and [State B], or if you moved frequently, a nexus study helps clarify your filing obligations. Many people accidentally file in states where they didn't have a legal obligation, creating unnecessary filing requirements and potential penalties.

Conducting a nexus study is a valuable step in identifying which states have the authority to tax your income. This process not only helps you minimize your tax liability but also enhances the effectiveness of your catch-up plan. It is also important to be aware of reciprocity agreements, which are arrangements between certain states that may allow you to owe taxes to only one state, even if you live in one state and work in another. Understanding these concepts can significantly impact your tax planning strategy.

Nexus Study Checklist:

Physical Presence: List every state where you lived, owned property, or had a home office.
Economic Activity: Keep a record of where your business's sales or services have taken place.
Platform Review: If you sell online, check which states are already covered by marketplace facilitator laws.

Step 2: Utilizing Voluntary Disclosure Agreements (VDAs)

One of the most powerful tools for catching up is the Voluntary Disclosure Agreement (VDA). Most states offer a VDA program for taxpayers with unfiled returns who the state's tax department has not yet contacted. In the context of a Voluntary Disclosure Agreement (VDA), states typically establish a "look-back period" of 3 to 4 years. This allows individuals or businesses who have not filed tax returns for an extended period, up to 10 years or more, to submit only returns for the most recent years within that look-back timeframe. As a result, the state may choose to waive any taxes owed for years outside this period, providing a more manageable compliance pathway.

In addition to limiting the time period for which you must file, a VDA almost always includes a waiver of penalties. Since penalties can often equal or exceed the tax owed over several years, this can save you thousands of dollars. However, the catch is that you must come forward before the state sends you a notice or starts an audit. Once they find you first, the VDA option is usually off the table.

Benefits of a VDA:

Limited Look-Back: You often only have to file the last 3 to 4 years of returns.
Penalty Waiver: States frequently waive all late-filing and late-payment penalties.
Fresh Start: After you finish your VDA, it's like hitting the refresh button; you're officially recognized as fully compliant in that state!

Step 3: Gathering Records Across State Lines

The biggest hurdle to catching up is often the lack of documentation. You will need W-2s, 1099s, bank statements, and business expense receipts for every year you are filing. If you have lost these records, you can request a "Wage and Income Transcript" from the IRS, which lists all the tax documents reported under your Social Security number. This is a vital first step, as it shows you exactly what the government already knows about your income.

For your LLC or business expenses, you may need to recreate your books. This involves going through old bank and credit card statements to identify deductible costs. Remember that states have different rules for what is deductible; for example, some states may not allow 100% bonus depreciation for certain years, requiring you to adjust your federal numbers to fit the local law.

Record Recovery Checklist:

IRS Transcripts: Order your federal transcripts to see a baseline of your reported income.
Bank Archives: Contact your banks to request archived statements if they are no longer available online.
State-Specific Rules: Identify which deductions are "decoupled" from federal law in each state where you are filing.

Step 4: Prioritizing and Filing the Returns

Once you have your data and your VDA approvals, it is time to file. We generally recommend filing your federal returns first, as many state returns use your "Federal Adjusted Gross Income" as their starting point. By getting the federal numbers right, you create a solid foundation for every state return that follows. If you owe more than you can pay, do not let that stop you from filing; getting the returns on record stops the failure-to-file penalties from growing and allows you to set up a payment plan.

After the federal returns are in, you should prioritize states based on their interest rates and the aggressiveness of their tax systems. Some states are much quicker to issue liens or levies than others. Setting up an "Installment Agreement" with each state allows you to pay off your debt over time in manageable monthly bites, protecting your bank account and your credit while you work through the backlog.

The Filing Order:

Federal First: Establish your total income base before moving to state-level filings.
High-Interest States: Focus on states with the most expensive penalties first.
Payment Plans: Negotiate monthly payments with each jurisdiction to stay in good standing.

Common Questions

How many years do I really have to file to catch up?

While the IRS generally recommends filing for the last 6 years under Policy Statement 5-133, some states may have different statutes of limitations. Using a Voluntary Disclosure Agreement can often limit your filing requirement to the last 3 or 4 years. Still, it's important to verify each state's rules to avoid missing deadlines or facing penalties.

What happens if I don't have the money to pay the back taxes?

You should still file. The penalty for "failure to file" is much higher than the penalty for "failure to pay." Once you file, you can apply for an Offer in Compromise or an Installment Agreement to pay what you can afford over time.

Can the IRS take my passport for unfiled taxes?

If you owe more than $62,000 (for 2024/2025) in "seriously delinquent" tax debt and the IRS has filed a lien or levy, they can certify that debt to the State Department, which may then deny or even revoke your passport. Catching up and setting up a payment plan prevents this certification.

Is it better to file all states at once or one by one?

It is usually best to coordinate the filings. Because many states share information with the IRS, filing a federal return can trigger state notices. By managing all filings together, you ensure your story is consistent across jurisdictions and that you are maximizing your tax credits.

Is your business audit-proof?

Catching up on unfiled multi-state taxes is not just about submitting old returns. It is about knowing where you truly had filing obligations, using VDAs before states contact you, rebuilding the right records, and sequencing the filings so penalties stop growing. We help you create a structured catch-up plan that gets you compliant while protecting as much cash flow as possible.
