After filling my Gstr 7 for confirming GST TDS Credit. the credit is reflected in my CASH LEDGER.
1) can I use this cash ledger balance for RCM PAYMENT.
2) Otherwise how can I claim refund of that cash balance.
3) Is the same cash balance also possible to be utilised in INCOME TAX PAYMENT say Adv tax.
