Monthly GST Filing is mandatory for businesses under the Goods and Services Tax (GST) regime, requiring them to submit details of sales, purchases, and tax paid each month. This ensures compliance with tax laws, helps avoid penalties, and allows businesses to claim input tax credits on purchases, reducing their tax liability. Filing GST monthly improves transparency in transactions, maintains accurate financial records for smoother audits, and ensures efficient tax management. In Coimbatore, staying compliant with monthly GST filing supports businesses in tracking their liabilities and maintaining operational efficiency through proper tax management.
