I am salaried taxpayer, intending to file it return fy 2014-15, problem - salary cash recd during yr, no appointment letter,no tds , not shown in bank

1. You can still file your ITR
2. But you need to pay income tax if the income exceeds the limit

1. Yes, salary earned by 2 or more companies can be shown in ITR
2. When you join a new organization, you need to declare your income from previous employer to the new employer
3. Once you do this, the new employer would consider the income from previous employer along with the current salary and deduct tax accordingly and issue form 16 for the total income.
4. This form can be used for filing your ITR in July

That's okay. You can declare salary paid in cash too even though there is no evidence. But if your present employer insists on evidence, then you have another option. You can declare such income (salary in cash) while you file your ITR. Whatever you declare will be considered as income but you need to pay tax on such income at the time of filing ITR. If you wish to declare such income for the purpose of ITR, then you do otherwise you may ignore.
