Economic nexus thresholds
All 45 sales-tax states' thresholds ($100K or 200 transactions) are verified and mapped to the seller's transaction data — no assumptions.
The most rigorous sales-tax compliance engine a growing seller can use.
Sales Tax Nexus Compliance & VDA Engine assembles a done-for-you state-tax remediation — quantifying historical exposure, negotiating Voluntary Disclosure Agreements to cap back taxes and abate penalties, filing registrations, and filing every periodic return on time in every state forever. The customer never logs into a tax engine.

Why compliance fails
A single unregistered state can trigger a balance-sheet event.
A growing seller that ships into 30–50 states but is registered in only a handful has built up years of uncollected sales tax — owed from the company's own pocket. States assess up to 50% penalties plus interest on tax never collected, and audit activity is rising into 2026.
Most sellers run this by hand, from memory, once or twice a year. The statute has not been read end-to-end since the last time it mattered. That is exactly where compliance gaps hide.
Sales Tax Nexus Compliance & VDA Engine exists to close that gap with a single, exhaustive standard applied identically to every engagement.

The benchmark
Measured against the letter of the statute — subsection by subsection.
We do not summarize the law and hope. Every engagement is scored against a versioned rule pack tied to the exact text of each state's economic nexus law and VDA program. These are the provisions each engagement is held to.
Voluntary Disclosure Agreements
Each state's VDA look-back cap (typically 3 years) and penalty abatement terms are identified and negotiated to minimize exposure.
Every required registration
Registration in every nexus state is completed, including marketplace-facilitator carve-outs and remote-seller permits.
Periodic return filing
Monthly/quarterly returns are filed on time in every state, with data reconciled to the penny and SCRA screened.
Transaction data normalization
Raw transaction history is cleaned and normalized to state-specific taxability rules, with edge-case SKUs flagged for review.
Board-ready exposure memo
A complete diligence file is produced, including exposure quantification, VDA agreements, registration confirmations, and filing history.
How an engagement is built
Intake to specialist release, with deterministic gates the AI cannot overrule.
AI extracts and drafts. Deterministic rules — running as code, outside the model — decide what is complete. A human specialist signs every release. That order is never reversed.
01
Free Nexus Study
Upload transaction history and state list. We return a free completeness read: which states you have nexus in, which registrations are missing, and estimated exposure.
02
Data normalization & lien searches
As your authorized clerical agent, we normalize transaction data, map to state taxability rules, and order any required lien searches.
03
Grounded drafting
VDA applications, registration forms, and return templates are drafted from validated data and the state rule pack — no legal opinions, no invented facts.
04
Deterministic completeness gates
Amounts reconcile to the ledger to the penny; nexus thresholds are verified; VDA look-back is computed; SCRA is screened. Any failure blocks release.
05
Specialist release
A licensed tax professional reviews the exception queue and signs the release. High-value or complex engagements route to attorney review first.
06
Delivery
You receive the engagement: exposure memo, VDA agreements, registration confirmations, filing calendar, and ongoing return filing — ready for the company to submit under its own name.

Why Sales Tax Nexus Compliance & VDA Engine
Built to be the most thorough option a seller has.
Documentation-complete, by design
The deliverable is completeness itself — every nexus determination and filing accounted for or explicitly exception-coded. Nothing is left implicit.
Deterministic, not vibes
The gates that decide completeness are code, not a model's opinion. A drafting error cannot slip past a statutory requirement.
In its lane, on purpose
We prepare documentation and run searches as your clerical agent. We never contact the state directly, give legal advice, or conduct the sale.

Simple, predictable, and aligned with a documentation standard — not a cut of any recovery.
- A free Nexus Study before you commit — see exactly what is missing.
- One flat fee per released Compliance Engagement; disclosed pass-through search fees.

FAQ
Questions, answered precisely.
Is Sales Tax Nexus Compliance & VDA Engine a law firm?
No. Sales Tax Nexus Compliance & VDA Engine, a service of Your Deputy, Obuke LLC, provides documentation-completeness services. It is not a law firm, does not provide legal advice, and does not represent you in any legal matter. Attorney review is available and recommended for high-value or complex engagements.
Do you contact the state or collect the tax?
Never. Sales Tax Nexus Compliance & VDA Engine is not a tax collector and does not contact state departments of revenue directly. The company remains the taxpayer and the party responsible for submitting all filings.
What makes an engagement 'complete'?
Completeness is defined by the statute: all nexus thresholds verified, VDA applications drafted, registrations filed, and returns prepared. Deterministic gates enforce each one before release.
How fast is it?
The standard SLA is five business days from complete intake to a specialist-released engagement. The free Nexus Study is returned much sooner and tells you exactly what is still needed.
How are you priced?
A flat fee per released engagement, plus disclosed pass-through search costs. No contingency and no percentage of any recovered amount or sale proceeds.
