You compare two lucrative-activity ISR regimes (same engine as the Guatemala ISR calculator):
- Profits (utilidades): annualize, subtract deductions + Q48,000 reference, 5%/7% brackets.
- Optional simplified on income: 5% up to Q30,000/month and 7% on the excess.
Not pequeño contribuyente and not employee payroll withholding.
Profits, simplified, or small taxpayer
| Path | What it taxes | Tool | |------|---------------|------| | Profits (utilidades) | Net income (income − expenses − deduction) | This page + ISR Guatemala | | Optional simplified | Gross income (5%/7%) | This page + ISR Guatemala | | Small taxpayer | 5% on gross income, SAT ceiling Q500,285 | Guatemala small taxpayer | | Salaried employee | Payroll withholding with Q51,024 in 2026 + IGSS | Guatemala net salary |
Low invoicing under the SAT ceiling? Start with small taxpayer. On a dependent salary? Go to net salary.
Results are an educational comparison. Formal election, thresholds, invoicing, and filings are defined by SAT and your accountant.
How to use it
- Reference monthly gross income (lucrative activities).
- Monthly deductions (if you model utilidades).
- Compare monthly tax and which regime is lower in the model.

FAQ
No. Pequeño contribuyente is a different track (5% on gross income and an annual SAT ceiling). This comparator faces utilidades vs optional simplified only. Use the small taxpayer calculator for the 5% quota and Q500,285 ceiling.
No. Payroll withholding (relación de dependencia, Q51,024 deduction in 2026 plus IGSS) is estimated in Guatemala net salary.
In the simplified model, tax is estimated on income with regime rates, not on net profit with detailed deductions.
