Analysts have predicted that the supermarket giant will report pre-tax profit between £1.093bn and £1.134bn, compared with £908m the year before.
The analysts added that Tesco would report solid UK results but warned that trading in its international operations could have been hit by an economic slowdown in Hungary and expansion restrictions in Thailand.
Meanwhile, Tesco has unveiled plans to sell cut-price own-label computer software.
Tesco said that Tesco Software, which will include an office suite, antivirus, CD/DVD burning and photo editing tools, would hit 100 Tesco stores next month.
Tesco buyer Daniel Cook said: "When it comes to computer software, there is little choice and prices are high. Our new range of software changes this, bringing choice and value to a market that has offered little of either."
