Damage (harm) caused to the state by tax arrears is fundamentallydifferent from the harm (damage) caused to the civil order, responsibility forwhich is provided by Art. 1064 of the Russian Civil Code. Concerning the damages to stateby tax arrears, these arrears don’t affect the initial assets of the state and couldn’t be reimbursedusing to the civil order (Art. 1064 of the Russian Civil Code).Concerning property deduction on personal income tax, it can't be equaled to tax (arrears)by using the legal fiction.
