Benefits and allowances in kind are fully taxable and valued at their cost to the employer or at market value, however items such as reimbursement of travel expenses, housing provided for the sole interest of the employer and moving expenses are considered non taxable income and are excluded from the tax calculation.
Individual taxpayers and employees are able to deduct from their taxable income interest paid during the taxable year on mortgages for acquisition and construction of lodging, pension savings and gains derived from the redemption of shares in certain investment funds and of gifts made for cultural or sport purposes (all of these with certain limits, depending on the annual gross income of the person).
