Direct answer
What is sales & use tax resolution?
Generally no — economic nexus is forward-looking from the date you crossed the threshold (volume or transaction count). We document the threshold-crossing date for each state.
State revenue departments are aggressive. Coordinated CPA representation prevents a single audit from cascading across jurisdictions.
Proof
Does sales & use tax resolution actually work?
Yes — here's what the IRS's own data shows about sales & use tax resolution outcomes, timelines, and acceptance.
Process
How does the sales & use tax resolution process work?
In 4 defined steps: nexus study → vda strategy → audit defense → forward compliance. Most clients see protective action within days, with full resolution measured in weeks to months.
- 01
Nexus study
We map sales by state, identify economic-nexus thresholds crossed, and quantify exposure year by year.
- 02
VDA strategy
Where appropriate, we file VDA applications (state-by-state or through MTC) to limit lookback, waive penalties, and quantify liability cleanly.
- 03
Audit defense
For states with open audits, we represent through the audit, contest assessments, and negotiate settlements.
- 04
Forward compliance
We coordinate with your sales-tax automation (Avalara, TaxJar) to ensure forward filings are clean.

Eligibility
Do I qualify for sales & use tax resolution?
Sales & Use Tax Resolution fits a specific set of taxpayer situations — and there are cases where a different strategy will get you a better outcome. Here's exactly who it's for and who it isn't.
Who this is for
- Businesses under state sales-tax audit
- Companies with multi-state exposure
- Sellers facing nexus assessments
When this isn't the right tool
- You've already received an audit notice from the state — VDA is no longer available; pivot to audit defense.
- Your exposure is single-state with minimal volume — simpler registration + back-filing may be more cost-effective than VDA.
What we handle for you
- Represent in state audits and appeals
- Negotiate voluntary disclosure agreements
- Defend against nexus and use-tax assessments
Investment
How much does sales & use tax resolution cost?
We engage on a written flat fee with no hourly billing — typical engagements range from a few thousand to mid-five figures depending on the factors below. Your initial consultation is free and you receive a written quote before any commitment.
The fee for your case depends on:
- • Number of states with exposure.
- • Whether VDA is available vs. audit defense.
- • Complexity of product taxability (SaaS, digital goods, services).
Your initial consultation is free. You'll get a written scope and flat-fee quote before any engagement.
Watch out
What mistakes should I avoid with sales & use tax resolution?
These are the four most common errors we see when taxpayers (or under-qualified preparers) handle these cases — each one can cost months of delay or trigger an outright rejection.
Registering before VDA
Voluntary registration ends VDA eligibility. Always run the VDA analysis first.
Ignoring use tax
Use tax exposure (purchased goods/services used in-state) often equals or exceeds sales-tax exposure for service businesses.
