Dear Sir,
You are still paying loan for the business in which there is no income. First of all, business is not closed because loan is still outstanding as an liability for the business for which repayment is being done by you. It is my advise to you to repay the business loan from the business bank account if any opened separately. As the repayment is being done from your salary account and not from your business income, business is still liable to repay you the same. After repayment of all business liabilities, set-off the remaining assets and liabilities and close the business.
1) Repayment of loan is not loss of the business it is an repayment of liability therefore you cannot set off of the salary income with the EMI. You are required to show salary income under the head Salary and business loss if any under the head Profit and Gains of Business or Profession. You cannot show salary income under other head. You can claim the TDS of Rs.18K deducted on your salary income from the total tax liability. Loss or Profit is calculated from the operating income and expenses of the business. In your case, it was development/manufacture of product or income from Android App and other routine expenses. Repayment of loan is not expense. Ineterest component in EMI is an expense.
2) As I told you earlier, business is not closed if there are Assets and liabilities outstanding in the books of accounts. In your annual Income tax return, you need to show Income and losses earned during the previous year. You need to disclose the salary income and business income or loss if any.
To close down the business, you need to surrender all the registrations etc.
Thanks
