Citation-grounded Virginia tax research

Tax research that cites the law by name.

Avercite reads the Code, the regulations, and the Rulings of the Tax Commissioner, follows the cross-references a keyword search misses, and shows its work — then declines to answer when the authority isn’t there.

Provenance, made visible

Every statement tied to a named authority — and you can see the chain.

The answer and the authorities behind it, side by side. Inline citations link to the authority rail, ordered by Virginia’s authority hierarchy — statute, then regulation, then the Rulings of the Tax Commissioner.

Illustrative example

Question

Is cloud-based software (SaaS) subject to Virginia retail sales & use tax?

Conclusion

Generally no. Virginia’s retail sales and use tax is imposed on sales of tangible personal property[1], and access to software hosted by the provider is treated as a nontaxable service rather than a sale of tangible property[2].

The Tax Commissioner has applied that distinction to cloud-delivered software, declining to impose the tax where no tangible medium changes hands[3] — but a bundled sale that includes tangible property can change the result, so the facts of the transaction control.

Honesty

When the controlling authority isn’t in the corpus — a federal question, another state, or an issue Virginia hasn’t squarely addressed — Avercite says so and declines to answer rather than guess. It is a research aid that supports a tax professional’s review; it is not legal advice and is not authoritative on its own.

Coverage · the architecture

An authority graph built for six Virginia layers.

Avercite is built as a typed authority graph spanning the six layers a Virginia tax answer can rest on. It is live in limited testing, and coverage of these layers is still being loaded — so Avercite tells you, per question, when an answer would fall outside what it can currently cite, and declines rather than guess.
