Safe harbour for information technology services sets a five-year filing and verification framework for eligible international transactions. Safe harbour for eligible international transactions involving provision of information technology services applies for five consecutive tax years once validly exercised, with the revenue threshold tested in the first year. The assessee must file Form No. 49 electronically by the due date, after which eligibility, transaction status and validity are verified electronically. If accepted, the assessee must file returns under the safe harbour provisions for each year, furnish annual statements for the following four years, and may withdraw the option only within six months from the end of the first tax year.
