New Delhi: As signs of revival of demand in the IT sector are improving, Tata Consultancy Services (TCS) will review salary increment plans by this month-end. "There has been no hike in the current fiscal. The demand-supply situation, however, has improved over last year. We review it (wage hikes) along with the business plan for the year, which will be happening somewhere by end of February or in March," TCS Chief Financial Officer S Mahalingam. Earlier this month, TCS announced that it would hire 30,000 people next fiscal, signalling that buoyancy was back. Talking about expectations from the upcoming budget, Mahalingam said the industry, as a whole, wanted the extension of the tax holidays that are provided to IT firms under Sec 10A/10B of the Software Technology Parks (STP) Act. Mahalingam also asked the government to clear the ambiguities in various policies related to direct tax code and SEZs.
