There will be no tax fair this year and the online system is down so you have to go to the office and submit. In order to show income, bank statement, salary certificate etc. have to be submitted. A copy of the bank statement should be kept along with the account of assets as proof. If you can't submit it yourself, someone else can come and submit it. Cannot be sent by post or courier as there is no way for the receipt slip to be sent to you from the tax office.
