penalty u/s 234F

What do you mean by non-taxable income?

Whether it exceeds 2.5 lakhs?

Whether filing of return is madatory in your case?

if your gross income before deductions U/s 80c is more than 2.5 lakh you have to pay Rs.1000 penalty

if gross income is less than 2.5 lakh then no need to pay 1000?

yes, it won't show you

No penalty under section 234F attracts if income is below the basic exemption limit (i.e.,2.5/3/5Lakhs)

so if the person is not required to file Return Of income and if he files a return of income declaring gross income below taxable limit, then 234f will not attract. this is my opinion, correct me if I am wrong
