Pick what you need. Each has its own page, its own process, its own turnaround.
Every desk runs on the same intake: send documents, get a checklist back, we file, you get the acknowledgement. No chasing.
PAN 49A
Form 49A filings, CR-01 corrections, and reissues after loss or damage — handled end to end, from KYC intake to the acknowledgement number.
GST
FORM GST REG-01 registration with correct HSN/SAC classification, plus the return filing that keeps the registration in good standing afterward.
CIBIL
A line-by-line read of your CIBIL or Experian report to catch wrong DPD marks, duplicate accounts, or incorrect limits — then a formal dispute to get them fixed.
ITR & FS
Head-wise income computed from your bank statements and broker P&L, reconciled against 26AS/AIS/TIS, then filed — plus Balance Sheet, P&L and Notes where books are needed.
Business Registration
PAN, TAN, Udyam, GST, Shop & Establishment, Gumasta, FSSAI, and the certificates lenders and tenders ask for — worked out for your specific business and tracked until each one is actually in hand.
Three steps, no office visit for most work.
