Rule version
Version PT-2026-v2, approved on 2026-10-17, last validated on 2026-10-17. Rules are effective from 2026-01-01 to 2026-12-31. Published rule versions cannot be edited; corrections are released as a new version.
Calculation assumptions
- Mainland Portuguese resident ordinary private-sector employee aged 18-64, without disability, IRS Jovem or expatriate relief. This estimate is before household expense and dependant credits.
- Individual and joint assessment are supported. Joint assessment combines both entered salaries and applies the statutory two-person quotient.
- Annual gross includes all salary and holiday/Christmas payments. Only annual income entry is supported. Monthly net is an average over twelve calendar months.
- Standard social-security rates are 11% employee and 23.75% employer. Gross must be at least EUR50,000, so employee mandatory contributions exceed the standard specific deduction; those contributions replace that deduction, rather than being added to it.
- IRS is estimated before optional expense credits and municipality participation rebates. No unentered household credits or municipal reimbursement are assumed.
- The statutory lower-band average rate and marginal excess rate from Article 68 are used. Additional solidarity tax applies above EUR80,000 taxable income.
