Features
Austria
Income Tax
Added the exemption with progression method of double taxation relief for tax residents outbound 1) to countries whose income tax treaties with Austria include this option or 2) to countries with no tax treaty where the top or average marginal rate exceeds 15%. Double tax relief for other outbound tax residents uses the existing foreign tax credit method.
The exemption with progression method applies the effective tax rate calculated on annual income to the Austrian-sourced income. A portion of the Austrian-sourced income may also be classified as nonrecurring, which is taxed at lower rates than recurring income.
Other Employer Costs
Added payroll tax of 5.81%, which includes contributions for the following:
Family Equalization Fund of 3.90%.
Severance Fund of 1.53%.
Chamber of Commerce Levy (using the Vienna rate of 0.38%).

The lookup caption will change to Yes - Prior to 2024 after the recalculation.
