Key legal question
Whether a person naturalized in Switzerland after age 25 remains liable for the military exemption tax despite having completed military obligations in the state of origin.
Extracted holding
Yes. Naturalization after the age threshold ends the duty to report for recruitment and to perform military service, but it does not remove the remaining military obligations, including the exemption tax.
Extracted reasoning
The court distinguished recruitment and military service duties from the separate obligation to pay the exemption tax. Completion of foreign military obligations does not exempt a person from Swiss tax liability under the applicable military service rules.
