Casual taxable person advance tax net of input tax credit clarified, and ISD excess credit recovery procedures specified. Advance tax for a casual taxable person is to be computed on the estimated net tax liability after accounting for eligible input tax credit. Long-running exhibitions beyond the casual taxable person period require normal registration without advance tax and may use the allotment letter as business proof. Excess input tax credit distributed by an ISD must be recovered from recipient units with interest and penalty; recipients may voluntarily deposit via the prescribed form, otherwise recovery proceedings may be initiated, and the ISD is liable to a general penalty.
