Voluntary Disclosure Agreements: Fixing Years of Unfiled Sales Tax
Discovering you should have been registered in a dozen states three years ago is a common and survivable problem. A VDA is the mechanism states built for it — trading a capped look-back and waived penalties for coming forward before they find you.
Published: · Updated:
Quick answer: A VDA lets an unregistered business come forward, pay the tax it should have collected over a capped number of years, and have penalties waived. You usually approach anonymously through a representative. The option generally disappears the moment the state contacts you first.
Why Unfiled Sales Tax Does Not Age Out
There is a widespread assumption that old tax problems eventually expire. For unfiled sales tax returns, they generally do not.
A statute of limitations usually starts running when a return is filed. If you never registered and never filed, in many states nothing has started running at all — so the assessable period reaches back to the date you first established nexus, not three or four years. A company that crossed a threshold in 2021 and never registered can be looking at every quarter since.
The liability is yours, not your customers'. You cannot realistically re-invoice past customers for tax you failed to charge years ago. Whatever the assessment, it comes out of margin — which is why capping the exposed period matters more than almost anything else.
What the State Is Actually Offering
A VDA is a negotiated trade, not an amnesty. Understanding which parts are on the table keeps expectations realistic.
| Component | Typical VDA treatment |
|---|---|
| The tax itself | Payable in full for the agreed periods |
| Interest | Usually payable, occasionally reduced |
| Penalties | Commonly waived — the core benefit |
| Look-back period | Capped at a defined number of years rather than open-ended |
Two of those rows are where the money is. Penalties compound on top of an already-growing balance, and an uncapped look-back is what turns a manageable number into an existential one. A VDA addresses both.
✅ Come forward
Defined look-back, penalties generally waived, terms known before you are identified.
❌ Get found
Assessment potentially back to first nexus, penalties and interest applied, and no negotiating position left.
The Anonymous Approach
This is the feature that makes a VDA low-risk, and it is the part most people do not know exists. In most states you do not have to identify yourself to start.
A representative presents the facts — the nature of the business, when nexus arose, approximate exposure — without naming the company. The state responds with the terms it will offer. Only once those terms are agreed does the business identify itself and sign.
The consequence is that exploring a VDA costs you very little. If the terms are unattractive, you walk away and the state never learned who was asking.
The Event That Closes the Door
A disclosure is only voluntary while the state is not already looking at you. Once it has made contact, the programme is generally unavailable in that state.
Contact includes more than a formal audit notice:
- A nexus questionnaire. These look like routine information requests. They are frequently the opening move, and answering one can close your VDA option.
- An audit notice for any tax type, not only sales tax.
- Prior correspondence about registration or filing obligations.
If a questionnaire arrives, get advice before replying. The response deadline is usually short, but a reply sent without understanding its effect can forfeit a materially better outcome that was available the day before it landed.
Is a VDA Always the Right Answer?
Not necessarily. It is a negotiation with real cost, and it is worth least when:
- Exposure in that state is small. If the historic liability is minor, registering and filing forward may be simpler and cheaper.
- You collected tax but never remitted it. This is a materially different situation. Tax collected from customers is generally held in trust, states treat failure to remit far more seriously than failure to collect, and relief is narrower.
- Nexus is genuinely doubtful. If it is unclear you ever had an obligation, establishing that may be a better use of the same professional fees.
The Multistate Tax Commission also runs a programme letting a business make one coordinated disclosure across several participating states1, which reduces the overhead of negotiating each separately.
The Five-Step Process
- Quantify the exposure state by state. Reconstruct taxable sales by state from the date nexus was established, and estimate the tax that should have been collected plus interest. Without a number, you cannot judge whether a VDA is worth doing.
- Confirm no state has contacted you. Check for nexus questionnaires, audit notices or prior correspondence in every state under consideration. Contact generally disqualifies that state, and applying anyway can worsen your position.
- Approach anonymously through a representative. Have a representative present the facts to the state without identifying the business, so terms can be negotiated before you are exposed.
- Negotiate the look-back and penalty terms. Agree the number of years the state will assess and confirm the penalty waiver in writing. These terms vary by state and are the substance of the deal.
- Register, file the back periods and stay current. Sign the agreement, register, file and pay for the agreed periods, and begin filing on schedule. A VDA that is followed by late filings undoes the benefit it bought.
This is not a do-it-yourself process. The anonymous approach depends on a representative, terms vary by state, and a mishandled application can cost you the protection it was meant to secure. Engage a multistate tax professional before contacting any state.

Frequently asked questions
Quick answers to the most common questions users ask.
What is a voluntary disclosure agreement?
A formal agreement with a state in which an unregistered business comes forward, reports and pays the tax it should have collected, and in exchange receives a limited look-back period and usually a waiver of penalties. It converts an open-ended historic liability into a defined, negotiated number.
How far back does a state look under a VDA?
A VDA normally caps the look-back at a defined number of years — commonly three or four — rather than running to the date nexus was first established. Without one, many states can assess back to that original date, because the statute of limitations generally does not start until a return is filed.
Does a VDA waive the tax itself?
No. You still pay the tax you should have collected, and usually the interest. What is typically waived is the penalty layer, which is the part that grows fastest. The trade the state is offering is certainty and a shorter look-back, not forgiveness of the tax.
Can I apply for a VDA anonymously?
In most states, yes. A representative approaches the state describing the facts without naming the business, negotiates the terms, and only discloses the identity once the agreement is settled. This is what makes the process low-risk: if terms cannot be agreed, the state never learned who was asking.
When does a state refuse a VDA?
Once it has already contacted you. A nexus questionnaire, an audit notice, or any prior enquiry generally disqualifies you, because the disclosure is no longer voluntary. This is why the timing matters more than the arithmetic — the option is worth most in the period before anyone is looking.
Do I need a VDA in every state?
Each state is a separate negotiation with its own terms, so exposure has to be assessed state by state. Where the liability in a state is small, registering and filing forward may be simpler. The Multistate Tax Commission also runs a programme allowing one coordinated application across multiple participating states.
