About Isamar
Payroll & Tax Logic Specialist | LatAm Compliance | Excel Calculators
Vina del Mar, Chile - 3:28 pm local time
✅ I turn complex labor & tax law into accurate, auditable calculations
✅ Built a tax simulator that matches official government results, exactly
✅ Building payroll logic for across LatAm
What I do:
I design payroll, severance, and tax calculators that are grounded in actual law-labor codes, official rulings, and government tax tables, not guesswork or copied formulas.
Most calculation tools on the market get the details wrong: outdated rates, incorrect legal bases, missing edge cases. I find those errors and make sure your numbers are correct, traceable, and ready to be trusted.
My work is built so your team can audit and replicate it. Every calculation step is visible and documented with its legal source - whether you need it as an Excel tool or as logic for a web application.
How I can help you:
- Custom payroll & severance calculators (Excel / Google Sheets)
-Tax calculation engines validated against official sources
-Legal logic translated into clear, replicable formulas for your dev team
-Financial reports, KPI dashboards, and bookkeeping
-Data analysis & automation (Excel, Power Query, Power BI)
I work 100% remotely, learn new tax and labor systems quickly, and document everything so you always know where each number comes from.
If you work with payroll or tax compliance in any Latin American country and you need it done right, send me a message. I'd be glad to help.
