A client-side compliance terminal that tracks contractor days-in-country against Permanent Establishment (PE) thresholds, flags CRITICAL risk automatically, and isolates a 15% tax cushion on the monthly payout of every CRITICAL contractor. All data stays encrypted in your browser.
Enclave Tax Core is built for companies that pay contractors and distributed staff across borders: finance leads, people-operations teams, founders and advisers who need to see Permanent Establishment exposure before it turns into a tax liability.
How it works:
Add each contractor with their monthly payout (in any of 10 supported currencies), their days in country so far and the statutory PE threshold that applies (183 days by default).
Every contractor is measured against their threshold. At 75% or more they are classified CRITICAL, otherwise SAFE, with the days remaining shown.
Worst-case exposure: the terminal isolates a 15% tax cushion on the monthly payout of every CRITICAL contractor and sums it into a single headline figure for board-level reporting.
Payouts are converted to your chosen base currency using live exchange rates.
Privacy by design:
100% client-side engine. No server, no database, no analytics.
Data is encrypted with AES-256-GCM in an IndexedDB vault in your browser. Your passphrase is the only key.
Encrypted backup and restore lets you move your data between devices.
Every subscriber gets the full terminal, with a 30-day free trial and no card required.
Figures are indicative planning aids only and are not tax or legal advice.

This listing offers one pricing dimension: Free. You get access to the terminal at no cost through this single usage dimension. There are no tiers, instance sizes, or usage add-ons to compare. Pricing does not scale with contractors, usage volume, or term length. Every user receives the same access under this one Free dimension, so there are no incremental charges to plan around.
Top-of-mind questions for buyers
What does the Free dimension give me access to?
You get the full terminal with no feature-gating. This includes PE threshold monitoring per contractor, automatic CRITICAL/SAFE risk classification, worst-case exposure modelling, and an encrypted local vault with backup and restore. There are no locked features behind the Free dimension.
Does my cost change as I add more contractors or data?
No. The Free dimension does not meter contractors, usage volume, or term length. You can track any number of contractors without incremental charges. The engine runs entirely in your browser, so adding data does not trigger server-side usage fees.
Where is my contractor data stored under this product?
Your contractor data stays in your browser, not on vendor servers. The local vault is encrypted, and your passphrase is the only key. You can create encrypted backups and move them across devices. No analytics or server-side storage is involved.
