I have completed govt work contract of govt of maharashtra of rs 16 lakhs. work contract was of only excavation work by JCB.Last week I have received the payment from govt department and I have paid all people's via check but they have not given me the bill invoice. i have paid the bills of jcb service providers via check as per their savings account name as they don't have current account.
No goods are involved in this work.
Is there any problem in income tax filing.
is there any invoice problem??
