Important Information

A 100% deduction means that 100% of an eligible expense can be deducted from taxable business profits. It does not mean a 100% reduction in the tax payable.

Important: 100% înseamnă 100% din cheltuiala eligibilă, nu o reducere de 100% a impozitului. Dacă un bun sau serviciu este utilizat și personal, se deduce numai partea profesională.
