El Salvador Personal Income Tax Guide 2026
El Salvador operates a territorial tax system — only income sourced within El Salvador is taxable. The Impuesto Sobre la Renta (ISR) is progressive with 4 brackets: 0% up to USD 4,064, 10% on USD 4,064–10,000, 20% on USD 10,000–20,000, and 30% above USD 20,000. The tax year follows the calendar year (January to December). The Dirección General de Impuestos Internos (DGII) administers all income tax.
Overview — Territorial Taxation
El Salvador's territorial tax system is one of its most distinctive features. Only income generated within Salvadoran territory is subject to ISR. This means foreign-source income — including dividends, interest, capital gains, and employment income earned abroad — is exempt from Salvadoran income tax. This territorial principle applies to both residents and non-residents, making El Salvador a highly attractive jurisdiction for internationally mobile individuals and businesses. The Dirección General de Impuestos Internos (DGII) under the Ministry of Finance oversees tax administration. Residency is determined by the 183-day physical presence rule, but the territorial nature of the system means tax liability depends primarily on the source of income rather than residency status.
ISR Tax Brackets 2026 — Annual Rates
El Salvador's progressive ISR has 4 brackets for the 2026 tax year:
- 0% — on the first USD 4,064 of annual taxable income (exempt)
- 10% — on taxable income from USD 4,064.01 to USD 10,000.00
- 20% — on taxable income from USD 10,000.01 to USD 20,000.00
- 30% — on taxable income above USD 20,000.00
The brackets apply to annual taxable income (after allowable deductions). A taxpayer earning USD 30,000 per year pays approximately USD 5,193.60 in ISR — an effective rate of ~17.3%. The calculation is: (USD 10,000 − 4,064) × 10% + (USD 20,000 − 10,000) × 20% + (USD 30,000 − 20,000) × 30% = USD 593.60 + USD 2,000 + USD 3,000 = USD 5,593.60.
Allowable Deductions
Salvadoran tax law allows individuals to deduct certain expenses from gross income before applying the progressive brackets:
- Personal expenses — up to USD 2,000 per year (medical, dental, education)
- Mortgage interest — interest paid on loans for primary residence
- Health insurance premiums — fully deductible
- AFP contributions — mandatory pension contributions (7.25%) are deductible
- ISSS contributions — mandatory health contributions (3%) are deductible
- Charitable donations — up to 10% of net income, to registered organisations
Total deductions cannot reduce taxable income below the minimum exempt threshold. Receipts and supporting documentation must be maintained for DGII audit purposes.
Employment Income
Employees have ISR withheld at source by employers through the payroll system (retención en la fuente). The employer calculates the monthly ISR based on the employee's salary, applies the applicable withholding tables issued by the DGII, deducts AFP (7.25%) and ISSS (3%) contributions, and remits the net tax to the DGII by the 10th of the following month. Employees receive annual tax certificates (Constancia de Retención) from their employers for filing purposes. Bonuses, commissions, overtime, and other remuneration are all subject to ISR withholding. The aguinaldo (Christmas bonus) up to one month's salary may be partially exempt.
Self-Employed & Business Income
Self-employed individuals and professionals are taxed under the same progressive ISR brackets. They must file quarterly estimated tax returns (Declaración de Renta) using Form 310 (F-310). Estimated tax is payable in quarterly instalments in April, July, October, and January. Annual returns must be filed by 30 April of the following year. Self-employed individuals can deduct business expenses directly related to generating income, including rent, utilities, supplies, professional fees, and depreciation of business assets. Proper accounting records must be maintained. Professionals (abogados, médicos, contadores) have specific withholding rules — clients must withhold 10% of fees and remit to DGII.
FAQs
Do I pay tax on foreign income if I live in El Salvador?
No, El Salvador's territorial tax system means foreign-source income is exempt from ISR. This includes salary earned abroad, foreign dividends, interest from foreign banks, and capital gains on foreign assets. Only Salvadoran-source income is taxable.
Do I need to file a return if my only income is from employment?
If all your ISR was withheld at source by your employer and you have no other Salvadoran-source income, you are not required to file an annual return. However, you may choose to file to claim a refund if excess tax was withheld.
Is the aguinaldo (Christmas bonus) taxable?
Yes, the aguinaldo is taxable as employment income. However, the first USD 1,500 of the aguinaldo is exempt from ISR. Amounts above USD 1,500 are subject to withholding at the employee's marginal rate.
Can married couples file jointly?
El Salvador does not allow joint filing. Each individual must file their own tax return on their own income. There is no income splitting for married couples.
