Tax Obligation Checker
Sales tax nexus, VAT and withholding checks for each jurisdiction or client you list, with thresholds, legal basis, estimated exposure and registration steps.
Built for finance leads and founders working out where sales tax nexus or other tax registration is triggered.
Why this work is hard
Finance leads and founders working out where their sales trigger tax registration spend hours on this by hand: finding the right sources, reading them, checking them against each other and writing up what matters. The work is repetitive, it is easy to miss something, and nobody can show where a claim came from.
Tax Obligation Checker does that work as a GREP AI agent. It takes a whole list in one run and returns one row per item. Every run delivers a sourced report, with every claim linked to its source.

FAQ
What does Tax Obligation Checker need to run?
Tax Obligation Checker needs jurisdictions or clients to check (one per line), what you sell, to whom, and how and sales and transaction counts per jurisdiction (one per line); existing tax registrations (optional) is optional.
How often does Tax Obligation Checker run?
It takes a whole list in one run and returns one row per item.
What does Tax Obligation Checker deliver?
Every run delivers a sourced report, with every claim linked to its source.
Can I change what Tax Obligation Checker does?
Yes. Every GREP AI agent can be cloned into your workspace, where you can edit its instructions, add your own sources and files, and change its schedule.
How does it decide a sales tax nexus status?
It compares your figures with each official threshold and marks it triggered (meets or exceeds), approaching (80% or more), not triggered (below 80%), or registered if you already hold the matching registration. Rows with no figure are marked unchecked.
How many jurisdictions can I check at once?
Up to 25. If you list more, it processes the first 25 and states how many were skipped.
Is this tax advice?
No. It is research support. Statuses and actions are recommendations for you and a qualified tax adviser to confirm, and rows with issues such as large exposure or unclear taxability are flagged adviser needed.
