An individual is a Serbian tax resident if their permanent residence or center of vital interests is in Serbia, if they reside in Serbia 183 days or more (continuous or with breaks) within any 12-month period beginning or ending in the tax year, or if they are posted abroad for Serbian diplomatic/consular or international-organization work. Where Serbia has a treaty with the other relevant country, treaty tie-breaker rules govern in cases of dual residency. Residents are taxed on worldwide income; non-residents only on Serbia-source income.
Serbia has no Controlled Foreign Company rules.
Interest and related costs on loans from related parties are fully deductible up to four times the taxpayer's net equity (ten times for banks and leasing companies) - net equity measured as the average of total assets less total liabilities at year start and year end, with related-party loans measured as a daily average. Where the 4:1 (10:1) threshold is exceeded, non-deductible interest is calculated proportionally to the excess.
Serbia has concluded double tax treaties with 64 countries, including Germany, Austria, Switzerland, China, the UAE, Russia, and most Balkan and European neighbors. Notably, Serbia has no comprehensive tax treaty with the United States.
