How is net salary calculated from gross in 2026?

Quick answer

  1. 1. Start from the gross salary in the contract.
  2. 2. Withhold CAS (pension) 25% and CASS (health) 10% from the gross.
  3. 3. Compute the taxable base: gross minus CAS, CASS and the personal deduction.
  4. 4. Apply the 10% income tax on the taxable base.
  5. 5. Net = gross minus CAS, CASS and tax; roughly 57-58% of gross for an average salary.

What the law says

  • CAS (pension contribution) = 25% of gross salary, borne by the employee.
  • CASS (health contribution) = 10% of gross salary, borne by the employee.
  • Income tax = 10%, applied after deducting CAS, CASS and the personal deduction.
  • The personal deduction lowers the taxable base based on income and dependents.
  • The employer withholds and pays these amounts and files Declaration 112 monthly.

Practical examples

  • Example: on a gross salary of 5,000 lei about 1,250 lei CAS and 500 lei CASS are withheld, leaving a net of roughly 2,900-3,000 lei after tax.
  • Example: on a gross of 8,000 lei the withholdings (CAS+CASS+tax) reach ~3,400 lei, so the net is around 4,600 lei.
  • Example: the personal deduction for one dependent lowers the taxable base by a few hundred lei and slightly raises the net.

Common mistakes

  • Applying the 10% tax directly on the gross without first subtracting CAS, CASS and the personal deduction.
  • Confusing CAM (2.25%, paid by the employer) with a withholding from the employee's salary.
  • Ignoring the personal deduction and computing a lower net than the real one.
  • Using outdated rates after they change mid-year.

How 4softhr helps

  • 4softhr prepares the pre-payroll data (days worked, absences, bonuses) the net-from-gross calculation relies on.
  • It automatically computes days, bonuses and leave per employee as a starting point for payroll.
  • It generates clear payslips that separate gross, withholdings and net.
  • It exports data for the accountant or for Declaration 112.
  • It integrates with 4conta from the 4b2b ecosystem for the tax and accounting calculation.
