Country support
Understand the tax workflow before you depend on it.
Run invoicing in EUR, GBP, USD or INR with the relevant country configuration. Rechvix calculates supported taxes and prepares evidence for accountant review. Tax support is specific to the workflow; it is not a blanket compliance certification.
EUR document workflows
Spain
Calculate Spanish IVA and recargo de equivalencia on supported transactions. Prepare an accountant workbook and trace each figure back to source records.
Scope and limitations
The VERI*FACTU record chain, QR, AEAT XML and submission client are implemented. They have not been tested against live AEAT. Rechvix is not certified and no declaración responsable has been issued. Exports are workpapers, not filed Modelo 303/390 returns. SII, IGIC and IPSI are not supported.
VERI*FACTU implementation status
GBP document workflows
United Kingdom
Calculate supported UK VAT and prepare a nine-box VAT worksheet, source registers and review checks for your accountant.
Scope and limitations
Rechvix does not file Making Tax Digital returns or claim HMRC recognition. Your accountant uses suitable filing software. Northern Ireland goods, flat-rate and cash-accounting schemes are outside the implemented scope.

United States
Apply state base sales-tax rates in the collection regions you configure. Keep invoice, payment and accounting records, and export the supporting figures.
Scope and limitations
Local city, county and district taxes, nexus decisions, product-specific state taxability, marketplace-facilitator rules and return filing are not implemented. Confirm calculations for your jurisdiction before relying on them.
US calculation scope
INR document workflows
India
Prepare GST invoices and accountant packages containing workbooks, source registers and eligible offline-utility CSVs, with review checks before export.
Scope and limitations
Your accountant validates and files returns. e-Invoice and e-Way Bill adapters run in sandbox or mock mode unless a live provider is configured and verified. ITC and reverse-charge coverage has documented limitations.

Currency and cross-border rules
Set the legal entity's base currency and the document currency; where the workflow requires it, enter an exchange rate. Currency selection does not choose a tax jurisdiction or establish compliance. Historical rates and advanced schemes have limits documented in the tax-regime reference.
Unsupported cases, including EU cross-border consumer OSS sales and some cross-border purchases, are refused rather than silently calculated. Review your actual transaction types with your accountant.
