Why GST applications from Chennai get stuck, and how we prevent it
- AddressAddress proof doesn't matchThe door number, ward or PIN on the electricity bill or property papers differs from the application. We match them before filing.
- Land papersProperty in someone else's nameIf the building or land is still in a parent's or grandparent's name, add the owner's consent letter and ID. We check the patta, chitta or tax receipt before uploading.
- AadhaarAadhaar authentication skippedWithout it, the officer can order a site visit and approval can take up to 30 days. We complete it on day one.
- PhotosUnclear photos of the premisesOfficers often ask for a photo showing the name board and the building. We tell you exactly what to click.
- LimitUsing the goods limit for servicesThe ₹40 lakh limit is only for businesses selling goods. If you also supply services, the limit is ₹20 lakh, and late registration means tax, interest and penalty on past sales.
- CodesWrong HSN/SAC or business typeChoosing the wrong codes or constitution leads to queries later. We select them based on what you actually sell.
- QueriesMissing the 7-day reply windowAn unanswered query (REG-03) leads to rejection. We reply within the deadline, with no extra fee.
