Because deductions reduce the amount of tax you would otherwise have to pay.

By donating to a municipality you want to support, money flows to that region as a donation, and part of your resident tax and income tax is deducted by the amount you donate. Since you also receive a return gift from the municipality, it allows you to save money advantageously while effectively reducing your out-of-pocket cost.
