Key legal question
Whether the increased social deduction for children must be applied when calculating premium subsidies for source-taxed persons.
Extracted holding
Yes. The social deduction in tax return item 35 also applies to source-taxed persons because the special regulation only defines the relevant taxable income and does not exclude ordinary income variables.
Extracted reasoning
The special regime for source-taxed persons refers back to the ordinary premium-subsidy rules unless it expressly derogates from them. Since the regulation does not state that income variables such as the higher child deduction are excluded, they remain applicable. This interpretation also matches the purpose of the ordinary subsidy scheme and avoids unequal treatment of families with children.
