urgent help needed

Deduct such sale in April 3B....

yes can Decrease the sale in april-18

but some experts says it is not correct as new FY starts

There is No way out , in GST while filing gstr1 for april 18 , it accepts the March18 invoices, so u can do so .moreover if its B2b invoice , it should reflect in recipient gstr2a

Just keep reco. statement for the same

hmm. thanx

my friend also suffer from one mistake
he made the mistake the on intra state supply he charges igst and mistakenly his accountant also paid igst in 3b but he files correct gstr 1 by showing cgst and sgst

now he is in problem that whether he should decrease current igst liability by same amount and Increase cgst and sgst liability , as he don't require to pay any more tax now whether he can do so
or do nothing ?

Take IGST credit with the amount wrongly charged....
