person is liable to get registered on 1.8.17 but he applied for reg after 30 days I. e. on 1.9.17 nd he get registration on 15.9.17 so his date of reg will be 15.9.17. .now my question is whether he can collect tax during 1.8.17 to 14.9.17? And if yes then how he can issue tax invoice without reg number?
