FAQ

Questions we hear every week

What does an accounting firm in Querétaro typically handle?
A full-service firm like HGS covers monthly bookkeeping, federal taxes (ISR, VAT, DIOT), payroll with IMSS/INFONAVIT, the Querétaro state payroll tax (ISN), statutory audits, and electronic accounting filings with the SAT.
Do you work with foreign-owned companies?
Yes. As an independent member of PrimeGlobal (300+ firms, 120 countries) we support foreign subsidiaries operating in Mexico, including USD/EUR operations and coordination with their home-country advisors.
What is REPSE and do I need it?
REPSE is Mexico’s mandatory registry for companies providing specialized services or making personnel available to clients. If you outsource or provide specialized services, you likely need it — we handle registration and quarterly compliance.
How is HGS different from other firms?
We built our own technology platform: automated CFDI surveillance, bank reconciliation, and fiscal alerts. In 16 years we have served more than 300 companies of every size.
