Most businesses discover their sales tax problem at the worst possible moment. If you find it first, a Voluntary Disclosure Agreement may be the most cost-effective path to getting clean.
What You'll Learn
- What a VDA is and how the lookback limitation reduces your exposure
- How penalty and interest relief changes the economics of coming forward voluntarily
- The Multistate Tax Commission program for businesses with exposure in multiple states
- When a VDA is not the right approach: and what disqualifies you
- How ACTSOLV evaluates and manages the VDA process
The window that matters: A VDA is only available before a state contacts you. Once an audit notice, nexus questionnaire, or any related inquiry arrives, the VDA option closes for that state. Finding the problem first is what makes the option available.
Common discovery moments
Most businesses find their sales tax exposure at one of three points:
- An audit notice arrives: the least favorable scenario; VDA is no longer available
- A deal closes and a liability surfaces in escrow: discovery during due diligence
- An internal audit or advisor flags the gap: the scenario where a VDA is still possible

What Is a Voluntary Disclosure Agreement?
A VDA is a formal arrangement between a business and a state tax authority. The business comes forward voluntarily to disclose and pay sales or use tax that was never collected or remitted. In exchange, the state offers two things: a limited lookback period and a waiver of penalties.
The lookback limitation
A state audit can normally reach back to the full statute of limitations: typically three to four years where returns have been filed, but potentially indefinitely where no return was ever filed.
A VDA limits the lookback to a defined period, usually three or four years, regardless of how long the actual liability has been building. For a business with six or eight years of unregistered activity, this is the most significant financial benefit of the agreement.
Penalty and interest relief
Penalties are typically waived entirely under a VDA. Most states assess penalties of 20 to 25 percent of unpaid tax: sometimes higher for substantial underpayment.
Interest is often reduced as well, though terms vary by state. The result is a smaller, more predictable liability: and a process the business controls rather than one the state controls.
The Economics of Coming Forward
The financial difference between a VDA and a standard audit is significant. Here is what the comparison looks like for a business that has been operating without collecting sales tax in a state for six years.
| Scenario | Years of Back Tax | Penalties | Interest | Outcome |
|---|---|---|---|---|
| Standard audit discovery | Up to 6 years (or more if no returns filed) | 20–25%+ of tax due | Full interest from due date | Largest liability, adversarial process, state controls timeline |
| VDA filed before state contact | 3–4 years (state-defined lookback) | Waived entirely | Often reduced | Smaller liability, non-adversarial, business controls timeline |
For businesses preparing for a fundraise or acquisition: Unresolved sales tax exposure is a standard due diligence item. Investors and acquirers will find it. A VDA filed before the deal closes converts a liability of uncertain size into a documented, resolved obligation: which is meaningfully better than a gap discovered during due diligence at a moment when negotiating leverage has shifted.
The MTC Program for Multi-State Situations
The Multistate Tax Commission operates a voluntary disclosure program that allows businesses to apply to multiple states through a single process. Participating states agree to standard lookback periods and penalty waivers, reducing the administrative burden of managing separate VDA negotiations across 20 or 30 states at once.
What the MTC program offers
- Single application process across multiple participating states
- Standardized lookback periods and penalty waiver terms
- Reduced administrative complexity for businesses with broad multi-state exposure
- Anonymous preliminary contact to assess terms before the business is identified
Where the MTC program has limits
- Not every state participates in the MTC program
- Some states offer better terms through their own direct VDA process
- The right approach depends on where exposure is concentrated
- A tax advisor familiar with each state's terms can identify the optimal path
For a business with exposure concentrated in a handful of high-liability states, direct state VDAs may produce better outcomes than the MTC program. For a business with thin but widespread exposure across many states, the MTC program's administrative simplification is often worth more than any marginal improvement in individual state terms.
When a VDA Is Not the Right Choice
A VDA is a valuable tool, but it is not the right approach in every situation. Three circumstances disqualify it or make it impractical.
An audit notice, nexus questionnaire, or any inquiry related to the unpaid tax closes the VDA window for that state. There are no exceptions.
For minimal liability in a single state, registering going forward without a formal VDA may be more practical. The process carries administrative cost and time that can exceed the savings on small exposures.
A VDA requires disclosing the full scope of liability for the covered period. Coming forward and failing to disclose all relevant periods or jurisdictions puts the business in a worse position than not filing at all.
The incomplete disclosure risk is significant: A business that comes forward under a VDA and later has additional undisclosed exposure discovered by the state loses the benefit of the agreement: and is now dealing with a state that knows it was not given the full picture. The VDA process requires a complete liability assessment before filing, not after.
How the VDA Process Works
The VDA process is structured to allow a business to assess its exposure and negotiate terms before identifying itself to the state. Here is how it typically proceeds.
The process takes anywhere from a few weeks to several months depending on the state and the complexity of the liability. The anonymous preliminary contact is important: it preserves the business's ability to walk away if the state's terms are not acceptable before the business has been identified.
The first step is a full liability assessment. A business cannot evaluate whether a VDA makes sense: or file one correctly: without knowing the complete scope of its exposure first. Gaps discovered after filing can cost the business the protections it came forward to obtain.
Discovered sales tax exposure? Act before the state does.
If your business has found sales tax exposure through a fundraise, acquisition review, or internal audit, ACTSOLV can assess the liability, evaluate whether a VDA is the right path, and manage the process from start to finish.
Frequently Asked Questions
What is a Voluntary Disclosure Agreement for sales tax?
A Voluntary Disclosure Agreement (VDA) is a formal arrangement between a business and a state tax authority in which the business comes forward voluntarily to disclose and pay sales or use tax that was never collected or remitted. In exchange, the state offers a limited lookback period and a waiver of penalties. The lookback limitation is typically three to four years, regardless of how long the liability has been building.
What is the lookback period in a VDA?
The lookback period in a VDA is the number of years of back tax a business must pay when coming forward voluntarily. Most states limit the VDA lookback to three or four years. Without a VDA, a state audit can reach back to the full statute of limitations: typically three to four years where returns have been filed, but potentially indefinitely where no return was ever filed.
Are penalties waived in a VDA?
Yes, penalties are typically waived entirely under a VDA. Interest is often reduced as well, though terms vary by state. The result is a smaller, more predictable liability than the business would face if discovered through a standard state audit.
What is the MTC Voluntary Disclosure Program?
The Multistate Tax Commission (MTC) operates a voluntary disclosure program that allows businesses to apply to multiple states through a single process. Participating states agree to standard lookback periods and penalty waivers, reducing the administrative burden of managing separate VDA negotiations across many states at once. Not every state participates, and some states offer better terms outside the MTC program.
Can a business file a VDA after receiving an audit notice?
No. A VDA is only available to businesses that have not already been contacted by the state about the liability in question. Once a state has sent an audit notice, nexus questionnaire, or any other inquiry related to the unpaid tax, the VDA option is closed for that state.
When does a VDA not make sense?
A VDA may not be the right approach when the liability is small relative to the cost and time involved in the process. For minimal exposure in a single state, registering going forward without filing a formal VDA may be more practical. A VDA also requires disclosing the full scope of liability for the covered period: a business that fails to disclose all relevant periods or jurisdictions is in a worse position than one that never filed.
