If you’ve discovered uncollected or unremitted sales taxwhether from economic nexus, product taxability mistakes, or system errorsthis guide explains how to use a Voluntary Disclosure Agreement (VDA) to limit past exposure and get compliant with sales tax.

1) Understand what a VDA isand why it helps
A VDA is a legal agreement with a state that lets a business voluntarily disclose past sales/use tax liabilities. In return, states typically:

• Limit the lookback period (often 34 years, varies by state), and
• Waive penalties (interest is usually still due).

Why it matters: If exposure spans six years, a VDA can cap the catch-up period to the lookback window instead of the full six.

2) Act before the state contacts you
VDA eligibility is generally lost once a state initiates contact (e.g., audit notice, nexus questionnaire).
Action: If you suspect liability on your sales tax or other items, start evaluating VDA options immediatelydon’t wait for a notice.

3) Verify the lookback period for each state
Lookback periods and interest/penalty rules differ by jurisdiction.
Action: Create a state-by-state matrix noting lookback, interest, penalty waiver rules, and documentation required.

4) Consider multi-state exposure (and the MTC option)
Selling into multiple states may mean multiple VDAs. The Multi-State Tax Commission (MTC) program can streamline voluntary disclosures across participating states.
Action: Map historical sales by ship-to state and prioritize states by exposure/risk.

5) Use anonymous filing where available
Many states allow representatives (e.g., CPA/consultant) to negotiate terms without initially revealing your identity.
Action: If you’re uncertain about proceeding, start anonymously to protect eligibility while you finalize exposure and strategy.

6) Assemble complete, audit-ready records
Incomplete or inaccurate disclosures of sales tax can void a VDA. What you’ll typically need is as follows:
• Gross sales and taxable sales by ship-to address (state and local),
• Tax collected vs. tax due (by period),
• Exemption certificates (validated and on file), and
• A ballpark liability estimate over the lookback.
• Action: Before applying, confirm you can produce periodized data and local allocations; many states require them within 6090 days after approval.
• Tools used for doing taxes

7) Budget for paymentand ask about payment plans up front
Not all states offer payment plans for VDA liabilities; some require a lump-sum payment. When available, terms vary and often must be requested with the initial application.
Action: Build a cash-flow plan based on conservative assumptions (no plan, lump sum), and request any payment plan in the application when the state allows it.

8) Secure go-forward compliance on Day 1
VDAs require you to register and remain compliant prospectively.
Action:
• Register for sales and use tax (effective date per agreement),
• Configure product taxability and correct rate sourcing,
• Implement filing cadence and reminders,
• Centralize exemption certificates, and
• Schedule periodic compliance reviews or automation.

When a VDA might not be necessary
If exposure is only 612 months in a single state, it can be more efficient to register with a backdated start date, file the missing returns, and request a penalty waiverespecially if professional sales tax VDA fees would exceed the benefit. Evaluate both paths.

Pre-filing checklist
• Exposure mapped by state and period (including locals)
• Lookback, interest, waiver rules confirmed
• Data by ship-to address exportable for all periods
• Exemption certificates validated or cured
• Payment plan policy known; cash ready
• Go-forward systems configured (rates, taxability, filings)
