Voluntary Disclosure Agreements (VDA) Guide

What Is a Voluntary Disclosure Agreement?

A Voluntary Disclosure Agreement (VDA) is a negotiated agreement between a business and a state tax authority. The business proactively discloses that it has not been collecting and remitting sales tax as required, agrees to pay the tax owed for a limited historical period, and commits to prospective compliance.

In exchange, the state limits the audit lookback period — typically to 3 to 4 years rather than the full unlimited period that applies when a state discovers the issue on its own — and waives or significantly reduces penalties.

VDA programs are available in virtually every state with a sales tax. Most are administered through the state revenue department's voluntary disclosure unit, and many states participate in the Multistate Tax Commission's Streamlined VDA program, which allows businesses to disclose to multiple states simultaneously through a single application.

When a VDA Makes Sense

A VDA is worth considering when your business has nexus in states where it has not registered or filed, and the potential historical liability is meaningful.

Specifically, a VDA makes sense when:

You have identified states where you have physical or economic nexus and have never registered. You have been collecting sales tax but not remitting it — one of the most urgent situations, as this can carry criminal exposure. You have significant historical exposure across multiple states and want to limit lookback periods and penalties before a state audit triggers discovery. You are preparing for a sale, acquisition, or investment round and need clean tax compliance across all jurisdictions. You have received an audit notice in one state and want to proactively clean up other states before the audit expands.

A VDA is generally not necessary if your nexus exposure is recent (you just crossed the economic nexus threshold), your historical liability is de minimis, or the state has already contacted you — at which point other resolution strategies apply.

The VDA Process

The voluntary disclosure process typically follows these steps:

Anonymous Pre-Disclosure Inquiry: Most states allow your representative to approach the voluntary disclosure unit anonymously to assess the terms before formally disclosing your identity. This allows you to understand the lookback period, penalty treatment, and any state-specific conditions without committing to the disclosure.

Application: Once terms are confirmed, the business submits a formal VDA application — either through the state's own program or through the MTC's multistate program. The application identifies the tax type, the period of non-compliance, and the reason for coming forward.

Liability Calculation: You calculate and submit returns for the agreed lookback period. This requires pulling historical sales data, determining taxability by state, and computing the tax owed. A professional representative manages this process to minimize the liability while ensuring accuracy.

Payment and Agreement: The state reviews your submission, confirms the agreed terms, and you pay the tax for the lookback period. In most cases, penalties are waived and interest may be reduced. The agreement is formalized in writing.

Prospective Registration: You register for a sales tax permit in the state and begin collecting and remitting going forward. The VDA is now complete.

Lookback Periods and Penalty Treatment

The lookback period is the number of years of historical liability the state can require you to pay as part of the VDA. Standard lookback periods under most VDA programs are 3 to 4 years, compared to an unlimited lookback if the state discovers the issue through audit.

Penalty treatment varies by state. Most VDA programs include a full penalty waiver, which is the primary financial benefit of coming forward voluntarily. Some states impose a reduced penalty rather than a full waiver, and a handful apply their standard penalty structure but reduce interest.

Interest is generally owed in full — VDAs do not typically eliminate interest on unpaid tax. However, interest only runs for the lookback period under the VDA rather than from the date nexus was first established, which significantly limits total interest exposure for businesses with long-standing compliance gaps.

The financial math is usually compelling: VDA tax plus reduced interest and no penalties is almost always less than the full exposure from an audit with unlimited lookback, full penalties, and compounding interest.

The Risk of Waiting

States are increasingly effective at identifying non-compliant sellers. They use third-party data from marketplace platforms, 1099-K filings, information-sharing agreements with other states, and targeted industry audit campaigns to find businesses that should be registered but are not.

If a state contacts you before you come forward, the VDA window closes. You are now subject to a full audit with unlimited lookback, full penalties, and potentially criminal exposure if you collected tax and did not remit it.

The risk calculus is straightforward: the longer you wait, the more years of liability accumulate and the greater the chance that a state finds you first. Businesses with multi-state exposure and meaningful historical liability should treat VDA analysis as urgent, not optional.

How Sales Tax Helper Can Help

Sales Tax Helper manages the full VDA process — from anonymous pre-disclosure inquiries and liability calculation through application, negotiation, and prospective registration. We have handled VDAs in every state and understand each state's program, including which states are more flexible on lookback periods and penalty treatment and which are not.

For businesses with exposure in multiple states, we coordinate multistate VDAs through the MTC program and develop a prioritization strategy based on exposure size, audit risk, and state-specific program terms. The goal is to resolve your historical exposure as efficiently as possible and position your business for clean, defensible compliance going forward.
