How do voluntary disclosure agreement negotiations actually work, state by state?

How does a VDA negotiation actually run, end to end?

A VDA is a six-stage procedural workflow, not a single negotiation event. The brands that move fastest through it treat it as such. Each stage carries different leverage, and the leverage at any given stage depends on what was preserved in the prior stage.

The six stages, in order:

1. Anonymous initial application. A CPA or tax attorney files the disclosure as the brand's representative. The submission describes the unidentified taxpayer's business, the periods at issue, the estimated tax owed, and the proposed lookback period. The state receives the disclosure without the brand's name.^[1][2][3][4]
2. State review and eligibility confirmation. The Department of Revenue confirms that no disqualifier applies (no prior written contact, no active registration in the state, no prior VDA for the same tax type) and issues preliminary terms. California typically responds within 30 to 60 days; Texas runs a similar cadence.^[1][3] Massachusetts and Pennsylvania run longer.^[5][7]
3. Agreement on lookback period and penalty waiver. California and New York cap the lookback at three years; Texas and Pennsylvania at four; Massachusetts and Illinois at three.^{[1][2][3][5][6][7]} Penalties are waived in full under the agreement. Statutory interest on the unpaid tax is generally not waived.
4. Identity disclosure and execution. The representative names the taxpayer. The agreement is signed by an authorized official of the state DOR and the brand. Until this stage, the brand can withdraw without the state holding its name on file.
5. Back-return filing. The agreement specifies a defined window (typically 30 to 90 days) for the brand to file back returns covering each period inside the capped lookback.^[1][2][3] Some states accept a consolidated return for the full period; others require period-by-period returns.
6. Payment and effective date. The brand remits base tax and statutory interest. Execution of payment triggers the effective date of the agreement and establishes a clean prospective start for compliance going forward.

End-to-end timing in well-defined programs (California, Texas) runs 60 to 120 days from initial anonymous submission to signed agreement. Moderate-predictability programs (Massachusetts, Pennsylvania) run 90 to 180 days. The MTC Joint Program adds a few weeks of front-end coordination but reduces total elapsed time when more than a handful of states are in scope.

Anonymous negotiation: where it holds and what disqualifies it

The feature that makes VDAs worth the professional cost is anonymity. In most states the brand negotiates through a representative (CPA or attorney) without naming itself until terms are agreed, so the brand can confirm the lookback cap and penalty waiver before it ever identifies. Brands that approach the state directly forfeit that leverage.

How anonymity functions in practice. The representative submits the disclosure describing the unidentified taxpayer (industry, sales channels, geographic footprint, product categories) and the periods at issue, but does not provide the brand's legal name, EIN, or registration identifiers. The state evaluates the disclosure on the facts presented and proposes terms. If the proposed terms are acceptable, the representative names the taxpayer and the agreement moves to execution. If terms are unacceptable, the representative can withdraw the application without the state having a name on file.

Anonymity is supported in California, New York, Illinois, Massachusetts, Pennsylvania, and Texas, and through the MTC Joint Program.^{[1][2][3][4][5][6][7]} The point at which identification is required varies: most programs require identification at the agreement-signing stage, not the application stage. Confirm the identification trigger with the representative before assuming anonymity persists past preliminary terms.

The single disqualifier that closes the VDA path is prior written contact from the state. A nexus inquiry letter, an audit notice, or any other written communication from the DOR regarding the brand's sales tax obligations disqualifies VDA for that state.^[1][3] The disqualifier is receipt, not response. A letter received last week, unanswered, still disqualifies. The scope is state-specific; a nexus letter from California does not close the VDA path in New York or any other uncontacted state.

Two additional eligibility gates apply per state: an active sales tax registration in the state (the brand is already on the state's rolls and faces a delinquent-return process, not VDA), and a prior VDA in the same state for the same tax type (most programs allow one VDA per taxpayer per tax type).^[4]

The sequencing implication is operationally important. A nexus letter often signals coordinated audit activity targeting a similar class of ecommerce sellers. The window for VDAs in uncontacted states compresses once one letter arrives. Brands managing a multi-state remediation portfolio treat uncontacted high-exposure states as time-sensitive and contacted states as immediate standard-registration candidates. The nexus inquiry letter response guide covers the standard-registration response path for contacted states.

The documentation package: what the state actually asks for

The documentation the state wants is the exposure schedule the brand should already have. The VDA application turns on a credible state-by-state taxable-sales-by-period schedule, so brands that quantified exposure first move fast, and brands that try to build it during negotiation stall.

What the representative submits in the initial anonymous package:

• A description of the unidentified taxpayer's business. Industry, sales channels (Shopify, Shopify Plus, BigCommerce, Amazon, Walmart, TikTok Shop), product categories, geographic footprint. Sufficient detail for the state to evaluate the nexus basis without naming the brand.
• The state-by-state taxable-sales-by-period schedule. Gross sales into the state by period, multiplied by taxable mix, multiplied by the proposed blended rate, equals base tax owed by period. Period structure follows the state's filing cadence (monthly, quarterly, or annual).
• Nexus-start evidence. The date economic nexus was triggered (threshold-crossing date with supporting sales data) or physical nexus began (first inventory placement at a 3PL, first remote hire, first contractor engagement). The basis for nexus is what supports the lookback period proposed.
• The basis for the lookback period. A statement that anchors the proposed lookback to the date nexus was triggered, bounded by the state's statutory VDA cap.
• A statement of relief requested. Penalty waiver and the contractually capped lookback window, with an estimated tax-and-interest figure the brand is prepared to remit.

Brands that built the exposure schedule for other purposes (audit committee review, deal diligence, financing event) typically arrive at the VDA package with the heavy work already done.

The documentation submitted with the application becomes part of the agreement record. Any reconciliation discrepancy that surfaces later (a missed Amazon FBA period, an unaccounted marketplace settlement adjustment, a product category that was misclassified as exempt) can reopen the conversation with the state. Brands that submit complete, source-cited schedules avoid this. The exposure schedule should reconcile back to source order data: Shopify or Shopify Plus order exports, marketplace settlement reports, ERP general ledger entries from NetSuite or QuickBooks Online. TaxCloud picks up the prospective filing chain after the agreement closes, with an audit documentation trail that ties each forward-going return back to the same source transaction data the exposure schedule was built from.

The MTC Joint VDA Program: how one application compresses multi-state work

For brands with multi-state exposure, the MTC Joint Program is the multiplier. Instead of running 15 separate state VDAs in sequence, the brand files once through the Multistate Tax Commission and the participating states process in parallel. The result is the difference between a six-month and an eighteen-month remediation.

How the program operates. The brand's representative files one anonymous application through the MTC's National Nexus Program. The MTC distributes the disclosure to a selected list of participating states (up to 37 states have participated in recent program cycles).^[4] Each state evaluates the disclosure independently and proposes terms within its own statutory framework. The MTC coordinates timing, consolidates communication, and tracks responses centrally.

What carries across states and what does not. The application is single; the lookback caps, penalty relief, and back-return filing windows are state-specific. California's three-year cap, Texas's four-year cap, and New York's AND-test threshold (NY Tax Law §1101(b)(8))^[8] all still apply when those states are in scope. The MTC does not standardize state terms; it standardizes the coordination layer.

Where the program does not reach:

• California and Texas do not participate.^[4] Both states administer their own VDA programs directly through CDTFA and the Texas Comptroller.^[1][3] A brand with exposure in either state runs a parallel direct application alongside the MTC submission.
• States outside the MTC member list. A brand's portfolio may include states that have not joined MTC's Nexus Program in a given cycle. Those states require separate direct VDA applications.
• Same disqualifiers apply per state. Prior written contact from any individual participating state still closes the VDA path for that state, even when the application is filed centrally through MTC.

The economics. MTC adds a few weeks of front-end coordination but reduces total elapsed time substantially because states process in parallel rather than sequentially. For a brand with 10 to 15 non-California, non-Texas states in scope, MTC typically resolves the portfolio in four to six months versus 12 to 18 months for the same states run individually. Representation fees through MTC are typically lower per-state than running each state separately, though the bundled engagement fee is meaningful in absolute terms.

Once MTC terms close and back returns are filed, the prospective filing chain begins. For SST states (which overlap heavily with MTC participating states), TaxCloud handles the prospective registration and consolidated filing across the 24 SST member states through Certified Service Provider infrastructure, separating the prior-period remediation from the forward-going compliance operation cleanly.

State program mechanics: California, New York, Texas, Massachusetts, Illinois, Pennsylvania

Procedural mechanics vary state by state. The table below covers the programs that most frequently appear in mid-market remediation portfolios.

California (CDTFA). The CDTFA program runs through an online application. The representative submits the disclosure describing the unidentified taxpayer, the periods at issue, and the proposed lookback. CDTFA typically responds within 30 to 60 days with preliminary terms. The three-year lookback cap is stated in program guidance and is rarely contested when nexus basis is clearly documented.^[1]

New York (DTF). The DTF program uses a three-year lookback and runs through the state's online portal. One nuance specific to New York: the state's economic nexus test (NY Tax Law §1101(b)(8)) requires both $500,000 in cumulative gross receipts AND more than 100 transactions over the immediately preceding four sales tax quarters.^[2][8] A brand below the transaction count may not have triggered nexus despite crossing the dollar threshold. Confirm nexus basis before initiating.

Texas (Comptroller). Texas runs a four-year lookback with a well-documented process. Texas does not participate in the MTC Joint Program, so a separate Comptroller application is required regardless of how many other states are handled through MTC.^[3] The Comptroller's VDA section handles the intake.

Massachusetts (DOR). Massachusetts intake is rolling. Response time varies more than California or New York. Three-year lookback applies.^[5]

Illinois (DOR). Four-year lookback. Illinois is also running a parallel if from August 1 through October 31, 2026, pursuant to P.A. 104-0006.^[6] For Illinois exposure that falls within the amnesty window, the amnesty program may provide overlapping relief; coordinate timing with the representative.

Pennsylvania (DOR). Three-year lookback. The program covers civil exposure only and does not provide criminal relief, which is not typically a concern for ecommerce brands with no fraud allegations.^[7]

After terms are agreed: back-return filing, payment, and the prospective chain

Once the agreement is signed, the procedural work shifts from negotiation to execution. The brand has a defined window (typically 30 to 90 days) to file back returns for the capped lookback period and remit the tax owed.^[1][2][3] Missing the window can void the agreement and reopen the open-ended exposure.

What execution looks like:

• Back-return filing for each period in the capped lookback. California requires period-by-period returns; the filing cadence follows the period structure that would have applied had the brand been registered. Texas, Pennsylvania, and Illinois have similar period-by-period requirements. Some states accept a consolidated return covering the full lookback; confirm format with the representative before drafting.
• Payment of base tax and statutory interest. Penalties are waived under the agreement. Interest is calculated at the state's published rate from each return's original due date through payment.
• Effective date. Payment triggers the effective date of the agreement. From that date forward, the brand is treated as a registered taxpayer in the state, with a clean record on the prior period.
• Prospective registration and filing. The standard state registration apparatus engages. For the 24 SST states, registration through a Certified Service Provider switches on consolidated filing across the SST footprint. For non-SST states, registration is direct and filing is state-specific.

The reader here has the procedural map. The decision frame (when VDA wins versus standard registration) is upstream, in VDA vs. standard registration. The work after the agreement closes is downstream: registration, prospective calculation, and a documentation trail that holds up at audit. TaxCloud is built for that downstream chain: registration across all 13,000+ jurisdictions through one API, consolidated SST filing across the 24 member states, and the audit documentation trail that ties each prospective return back to the source transaction data the exposure schedule was originally built from.
