Hello, My friend got a notice from income tax department in regards of non filing income tax return for AY2014-2015. His total taxable income was near about 236000 and he paid tds for that income but he didn't file income tax return. He has also fd deposit of 2.5 lacs where he received interest of near about 20000 which is not included in above taxable income. Means tax is not yet paid on that amount. Now my query is how he can handle this notice? How much would be penalty / interest amount? Please guide.
