Questione giuridica chiave
Whether the cantonal tax appeal and complaint were filed within time after service of the objection decision.
Decisione estratta
The decision was deemed served when placed in the taxpayer's letterbox on 2011-01-11; the deadline expired on 2011-02-10, so the filing on 2011-02-13 was late.
Motivazione estratta
For tax decisions, service is sufficient when the addressee can take cognizance; actual reading is unnecessary. A-Post-Plus allowed proof of delivery, and the taxpayer's speculative objections did not rebut it.
