About CensusAudit
Founded by the inventor of AvaTax. 100% Navy veteran-owned. Patent pending.
The founder
Rory Rawlings founded and architected AvaTax — the original sales-tax automation engine, which processes transactions for most of the Fortune 500. He wrote the taxability-content codes that still ship with the dominant product in this category, and he understands — because he designed it — that the engine’s point-in-polygon method was a cost-control trade: resolve to the ZIP code, drop a centroid, and accept that some percentage will land on the wrong side of a jurisdiction line.
In 2026, Mr. Rawlings filed a multi-part patent that replaces the approximation with deterministic accuracy, first deployed in SALTklaw. The first part is a parcel spine: every address resolved to the actual cadastral parcel, the parcel polygon tested against the jurisdiction boundary polygon to determine whether the transaction sits inside, outside, or across the line — making jurisdiction assignment deterministic. The second part is a consistent classification system that reads the controlling statute, regulation, and court decision directly, producing the same taxability answer for the same product and the same law, every time, with the citation attached.
CensusAudit applies that invention to the state-audit side. The same parcel spine that SALTklaw uses to determine tax for sellers, CensusAudit uses to audit those determinations for states — with the statute citation attached to every line. The technology is the same. The buyer is different. The data governance is separate and verifiable.
Before founding AvaTax, Mr. Rawlings served in the United States Navy. CensusAudit is a 100% Navy veteran-owned business.
Why a separate company
SALTklaw sells compliance to sellers. CensusAudit sells the audit capability to the states that audit those sellers. Inside one brand, every seller prospect eventually asks whether their vendor is arming their auditor — and there is no good answer.
Two companies with genuinely separate data governance is the answer. And it preserves the flywheel rather than losing it: a state that adopts the census audit has a direct interest in sellers running the compliant upstream product, because “this seller uses SALTklaw, the audit is already done” is a real reduction in that state’s audit cost. Same fact, opposite optics. The separation is what allows the upside without the trust problem.
Hard commitment: CensusAudit and SALTklaw maintain no shared customer data. No seller’s transaction data can ever reach a state through a sister company. This constraint is structural, not aspirational — it is why CensusAudit is a separate company and not a SALTklaw product line. It is stated publicly so every seller can verify it independently.
The name
Census is the auditor’s own term of art — examining an entire population rather than a sample. The name states the differentiator in the buyer’s vocabulary, in one word, against the exact method it replaces.
