Calculation assumptions

• The order follows article 96: first set-off against interest income, then 30 % of the year's ROL, and last the ROL capacity carried forward from earlier years.
• Enter the ROL capacity carried forward as an amount already reduced to 30 %, as paragraph 7 defines it. Only include amounts generated in the last five tax years: the calculator does not check their expiry.
• Financial intermediaries and insurers, public infrastructure projects, the domestic tax group and outright non-deductible interest are not covered. You enter the ROL yourself, already worked out under the tax rules.
