Sales Tax VDAs: How Behind Sellers Come Clean (Without Panic)

You just realized you've owed sales tax in one or more states, possibly for years. Before you spiral, here's the single most useful thing to know: about 40 states participate in a formal multistate program, and many others run their own, that rewards you for coming forward before they find you (MTC). It's called a voluntary disclosure agreement, and the deal is straightforward. You register, file, and pay a limited window of back tax, usually three to four years. In exchange, the state waives penalties and agrees not to reach further into your past.

That trade is the difference between a scary-but-bounded cleanup project and an open-ended audit where a state can assess every year you've ever had nexus. If you haven't already, read our catch-up guide for forgotten filers for the full triage process. This post goes deep on the VDA itself: what you get, what it won't fix, and how to apply without revealing who you are until the deal is signed.

Key Takeaways

• A voluntary disclosure agreement (VDA) is a deal with a state: you come forward and pay a limited lookback of back tax, and the state waives penalties and doesn't assess earlier years.
• The standard lookback is 36 to 48 months. If your only connection to a state is economic nexus, the lookback starts no earlier than that state's economic nexus implementation date (MTC lookback chart).
• Penalties are waived; the tax itself is always owed, and interest is usually owed too. Texas is a notable exception that waives interest (Texas Comptroller Pub. 96-576).
• The big carve-out: tax you collected from customers but never remitted must be paid in full, with no lookback cap.
• You can apply anonymously. The MTC's multistate program identifies you only by case number until you sign, and about 40 states participate (MTC).
• Prior contact from the state about that tax type disqualifies you, which is why waiting is the most expensive move you can make.

What Is a Sales Tax VDA?

Voluntary disclosure agreement (VDA): a binding agreement between a taxpayer and a state tax agency in which the taxpayer voluntarily registers, files returns, and pays sales tax for a limited "lookback" period, and the state agrees to waive penalties and not assess tax for periods before the lookback. The offer exists only if the taxpayer comes forward before the state makes contact.

States created VDA programs because they'd rather collect a few years of tax voluntarily than spend audit resources hunting non-filers. You benefit because the state formally caps how far back it will go. Without a VDA, an unregistered seller in many states has little or no statute of limitations protection: California, for example, can otherwise reach back eight years, versus three under its voluntary disclosure program (CDTFA), and a state can assess penalties and interest on all of it. (For what that unmanaged path looks like, see What Happens If You Don't File Sales Tax.)

The largest program is run by the Multistate Tax Commission (MTC), whose Multistate Voluntary Disclosure Program lets you settle with multiple states through one uniform procedure. About 40 states, including D.C., participate through the MTC's National Nexus Program. Most states also run their own direct programs, like Texas's (Pub. 96-576) and California's (CDTFA out-of-state program).

What Do You Actually Get?

A VDA waives penalties and caps the lookback. It does not erase the tax, and in most states it does not erase interest. Here's the honest ledger, based on the MTC's default terms:

Two things in that table deserve emphasis. First, Texas is unusually generous: under Pub. 96-576, "statutory penalties and interest will be waived," with the sole exception of interest on tax you collected and didn't remit. Under the MTC default, interest generally survives the deal. Second, that "collected but not remitted" row is important enough to get its own section below.

How Far Back Will They Look?

The standard lookback is 36 to 48 months. Per the MTC's lookback period chart, 36 months is the most common period among participating states, while Arizona, Kentucky, Maryland, Michigan, New Jersey, Texas, and Washington use 48 months. So "three to four years" is the honest planning range.

There's a detail here that dramatically helps many online sellers. If your only connection to a state is economic nexus, meaning you crossed a sales threshold but never had physical presence there, the MTC chart states the lookback "would commence not earlier than the state's sales/use tax economic nexus implementation date." In plain terms: a state can't use a VDA to reach back before the date its own economic nexus rule took effect, no matter how long you've been selling.

Run the math before you assume the worst. Many forgotten filers imagine a decade of exposure when the actual VDA number is three or four years of tax in the states where they genuinely crossed thresholds. If you're still working out which states those are, start with I triggered nexus, now what?

The One Thing a VDA Won't Fix

If you collected sales tax from customers and never sent it to the state, a VDA will not cap that exposure. This is the sharpest edge in the whole process, so read it twice.

The MTC lookback chart is explicit: "sales/use tax collected from others must be remitted in its entirety, may involve non-waivable penalties, and may cause the lookback period to commence when such tax was first collected." Texas says the same thing in Pub. 96-576: the standard four-year lookback applies, but there is "no limit on the lookback period for taxes collected and not remitted," and interest on that tax isn't waived.

The logic is simple. States treat collected tax as their money that you were holding in trust. Not remitting it isn't a filing lapse; it's keeping funds that belonged to the state from the moment your customer paid them. This is why the first diagnostic question in any catch-up project is: did you ever have tax collection turned on in your cart or channel settings without filing returns? If yes, a VDA still helps (it resolves the situation and can waive some penalties elsewhere), but the collected amounts are owed back to day one. If you never collected at all, which describes most forgotten filers, this section doesn't apply to you and the lookback cap works as advertised.

Can You Apply Anonymously?

Yes, and this is the feature that should lower your heart rate the most. Under the MTC program, your identity stays hidden until the deal is done. The Commission "treats the applicant's identity as confidential during the voluntary disclosure process" and "will disclose an applicant's identity to a state only after the applicant has entered into a VDA with that state." Until you sign, the state knows you only as a case number (MTC MVDP).

That means you, or a professional acting for you, can describe your facts, learn exactly what a state will offer, and see the terms in writing before anyone knows your business name. If the terms are unacceptable, you can walk away without having painted a target on yourself.

Texas works the same way through representatives: Pub. 96-576 allows a representative to initiate contact with the Comptroller anonymously on your behalf (the contact point is [email protected]). California's out-of-state program similarly allows an anonymous written request for a pre-application opinion (CDTFA).

This is exactly the kind of scoping work a service can do for you without exposure. Taxero's Forgotten Filer service handles back registrations and returns, including sizing your VDA exposure state by state before your name goes on anything.

One State or Many? The MTC Multistate Program

If you're behind in several states, you don't have to negotiate separately with each one. The MTC's Multistate Voluntary Disclosure Program lets you settle with multiple states through a single uniform procedure, coordinated by National Nexus Program staff. About 40 states plus D.C. participate; check the MTC's member list for whether your states are included.

One filter to know before applying: the MTC won't process an application for a state where your good-faith estimate of tax due for the lookback period is under $500. That's a practical materiality floor. If you owe a state $300 over four years, the answer usually isn't a VDA; it's often simply registering prospectively and moving on. This is also why a rough exposure estimate, state by state, is step one before any application goes out.

The multistate route makes the most sense when the same facts (say, FBA inventory or steadily growing direct sales) created nexus in many states around the same time. One narrative, one application package, many settlements.

What Disqualifies You

Prior contact from the state kills eligibility. The MTC's rule: "Prior contact between a state and the taxpayer concerning a tax type disqualifies the taxpayer," and contact "includes filing a tax return, paying tax, or receiving an inquiry from the state regarding the tax type" (MTC MVDP). Texas applies the same principle: you're eligible only if the Comptroller hasn't already contacted you (Pub. 96-576).

Notice how low the bar for "contact" is. A nexus questionnaire in your mailbox counts. A notice about the tax type counts. You don't have to be under audit to lose the VDA option; you just have to be on the state's radar first.

This is why waiting is the enemy. Every month you sit on the problem is a month in which a marketplace data-sharing program, a state discovery unit, or a routine questionnaire can find you first, and the moment that happens, the penalty waiver and the lookback cap are off the table for that state. The forgotten filers who end up with the worst outcomes usually aren't the ones who owed the most. They're the ones who knew, waited, and got contacted before they acted.

Real Examples: Texas vs California

Concrete terms make this less abstract, so here are two big states side by side.

Texas (Pub. 96-576): You're eligible if the Comptroller hasn't contacted you. The standard lookback is four years. Penalties and interest are both waived, which is more generous than the MTC default where interest usually survives. The exceptions track everything above: no lookback limit and no interest waiver for tax collected and not remitted. A representative can open the conversation anonymously. If Texas is one of your states, our Texas sales tax nexus guide covers the thresholds that determine whether you owed tax in the first place.

California (CDTFA Out-of-State Voluntary Disclosure Program): For qualifying out-of-state sellers, the program limits assessment to three years instead of the eight-year period the CDTFA can otherwise apply, and waives late filing and late payment penalties. You must file Form CDTFA-38 within 30 days of registering, and you can request an anonymous written opinion before committing. California also runs a separate in-state voluntary disclosure program for use tax, so in-state facts aren't a dead end either.

The pattern to internalize: the deal is real in both states, the anonymity route is real in both states, and the terms differ enough (interest waived vs owed, 4 years vs 3) that state-by-state reading matters before you apply.

DIY vs Getting Help

You can do a single-state VDA yourself if your facts are simple: one state, clear nexus start date, no tax ever collected, clean sales records. The state program pages linked above spell out their own procedures, and the anonymous pre-contact options mean even a DIY applicant can ask questions safely.

Getting help earns its cost when any of these are true:

• Multiple states. The MTC multistate route, exposure estimates per state, and the $500 floor all reward someone who has run the process before.
• You collected tax somewhere. The uncapped exposure for collected-not-remitted tax changes the strategy, and you want that scoped precisely before anyone contacts a state.
• Your nexus start dates are fuzzy. The economic-nexus lookback rule can cut years off your bill, but only if you can document when thresholds were actually crossed.
• You're too anxious to be objective. A professional can run the anonymous scoping conversation while you keep running your business.

Either way, the sequence is the same: estimate exposure per state, decide VDA vs simple prospective registration per state, apply anonymously, sign, register, file the lookback returns, pay, and stay compliant going forward. Taxero's Forgotten Filer service handles back registrations and returns end to end, so the cleanup and the ongoing filings don't land back on your desk.

FAQ

Will a VDA erase the sales tax I owe?

No. A VDA waives penalties and limits how many years the state can assess, but you still pay the tax for the lookback period, and in most states interest on it too. The MTC default is that "interest is due on unpaid tax obligations incurred during the look-back period unless expressly waived by the state" (MTC). Texas is a notable exception that waives interest (Pub. 96-576).

Is a VDA the same as sales tax amnesty?

No. Amnesty programs are temporary, legislature-created windows that come and go. A VDA is a standing program available year-round in about 40 states through the MTC, plus many direct state programs, with negotiated, written terms (MTC). If you're behind now, a VDA is the tool that actually exists now; waiting for a hypothetical amnesty means risking the prior-contact disqualification in the meantime.

Can the state find out who I am if I apply and back out?

Not through the MTC process. The Commission discloses an applicant's identity to a state "only after the applicant has entered into a VDA with that state"; before that, you're a case number (MTC). Texas and California similarly allow anonymous initial contact through a representative or written request.

What if I only crossed economic nexus thresholds recently?

Your exposure may be smaller than you fear. For sellers with no physical presence, the MTC lookback starts no earlier than the state's economic nexus implementation date (MTC lookback chart). Start by pinning down when you actually crossed each state's threshold; our guide to economic nexus walks through the tests.

The Bottom Line

A VDA converts an unbounded, panic-inducing unknown into a fixed project: three to four years of back tax, penalties waived, negotiated anonymously, done once. The offer has one expiration trigger, and it isn't a date; it's the state contacting you first. If you've realized you're behind, the productive move this week is a state-by-state exposure estimate, not another month of worrying. Start with Taxero's Forgotten Filer service, or at minimum, work through the catch-up guide and put real numbers on the problem.
