Employees on hourly wages and tax cards

  • OsloMet deducts all hourly wage earners by percentage, not by the tax table. Both hourly wage earners that has OsloMet as a secondary employer and as the main employer are deducted by percentage.
  • Hourly wage earners are deducted by percentage to avoid deducting too little tax. As your employer, OsloMet is responsible for the correct tax deduction.
    • Tax table deductions are made on the assumption of a fixed salary each month, which results in that the deduction becomes lower and lower the less you earn, so as not to deduct anything if the gross amount is low. In these cases, the correct tax amount is not deducted.
  • If you, as an hourly wage earner, believe that the percentage of taxation will be too high, you need to log in to and change your tax card.
  • Section for payroll can in special cases change to table deductions for hourly wage eployees. In such cases, it will be the hourly employee's own responsibility to check that the tax deduction is not too low, and OsloMet is not responsible for the possible consequences of too low tax deductions.
