While verifying IT liability using income tax calculator shown in IT portal, an error was noticed. When a person having a total income after standard deduction of Rs. 50,000 amounts to Rs. 5,60,000. As per the new Regime, person having Gross total income up to 7,50,000 does not have any tax liability. But the tax calculator shows a tax liability as per the new regime of Rs. 3,120. Is it Correct?
