An entry level (1 year exp) Software Engineer makes around Rs 1,50,000 to Rs. 5,00,000. Companies like google are extremes, they pay 8L (eight lakhs) to freshers.
3-5 years experienced s/w engineer should get something around 6 lakhs to 5 lakhs.
The general rule is, the salary = 2 x (years of experience), where experience is greater than 3. That means a 10 years experienced guy should get around 20 Lakhs.
Above figures are per-annum, before taxation.
The text for software engineers is deducted at source (TDS) through payroll. There is little chance (ie., almost no chance) of a s/w enginner not paying tax.
