Questione giuridica chiave
Whether effective property maintenance costs may again be deducted after the first five full tax years following acquisition, absent an express request for the lump-sum deduction.
Decisione estratta
Yes. After the first five full tax years, the effective-cost deduction again applies as the default rule unless the taxpayer expressly chooses the lump-sum deduction.
Motivazione estratta
Section 9 of the ordinance makes effective costs the rule, lump-sum deduction the exception. The five-year rule only temporarily restricts the taxpayer to the lump sum; once that period ends, the default effective-cost deduction returns regardless of whether the year is even or odd.
