All employees must belong to a social security plan which includes insurance for work-related accidents and illness, sickness, pregnancy, disability, old age and death. Contributions as a percentage of gross salary are payable by individual employees and employers. Employee contributions are deductible in determining taxable income. Currently (2004) employees pay 14% and employers pay 19.5% up to an upper earnings level of TL 2,886,975,000 per month.

A foreign national who is covered under the compulsory social security system of his or her home country is not required to pay social security premiums, provided proof of foreign coverage is filed with the local social security office. If the employee is not subject to foreign social security, full contributions would generally be imposed.
