### **GSTR-3B Due Date Note (State-wise / Group-wise)**

For monthly filers, GSTR-3B is due on **20 March 2026** for February transactions.

Taxpayers should reconcile input tax credit thoroughly before filing to prevent notices or reversals during year-end assessments.

### **Note on Professional Tax**

If your state mandates monthly Professional Tax, align payments with payroll processing. Due dates remain state-specific and must be verified locally.

## **Actionable planning checklist**

### **Two weeks before due dates**

- **20th:** File GSTR-3B and GSTR-5A

## **Year-End Corner Cases to Watch**
