Hello, I am a salaried individual. I prepared and submitted my ITR for A.Y. 2016-17 online through my account. After putting in figures for salary and TDS deducted, total tax payable was Rs. 7590. I should have paid the tax first and then submitted the return by putting paid amount as self-assessed tax. However, by mistake, I submitted the return first and then paid the amount (but before e-verifying the return). After tax-payment through Challan 280, I e-verified the tax-return through my net banking. Now, the acknowledgement I have received still shows as 'Tax Payable' of Rs. 7590. I want to know if this would be considered as faulty return? If so, the remedy thereof.
