About Reverse Tax Hub.
Building high-fidelity calculation engines for corporate and individual accounting procedures.
Our Mission
Reverse Tax Hub was founded to address a simple deficiency in financial web tooling: slow, bloated, ad-ridden calculation interfaces. We designed our engine from the ground up utilizing edge-compiled static builds (Astro JS) and client-side instant computation scripts to guarantee sub-millisecond calculation updates with zero layout shift.
Verification Standards
All standard rates preloaded within our US State and Global VAT directories are checked and verified against official administrative sources. Our rates are audited regularly to reflect active tax legislations for 2026.
- US State tax rates are pulled directly from local Department of Revenue publications.
- Global VAT and GST presets are cross-referenced with local central taxation authorities.
- Range calculations follow standard decimal backing algorithms to avoid compounding rounding errors.
Careers
We are always looking for software developers, accountants, and taxation operations specialists who want to help automate global transactions.
