Which exact GST returns do you need to file to stay out of trouble?
Government scrutiny is brought by mismatched business operations to the tax forms not meant for them. Filing late freezes your cash flow and forces you to pay strict daily fines. We process your data and submit these mandatory filings well before the deadlines to keep your compliance record clean:
- Handling your sales records on GSTR-1: Every single invoice you give to a customer needs to go onto the government system. We upload these bills every month or quarter so your clients can actually claim their tax credits back.
Â
- Sorting out the monthly GSTR-3B tax payment: You cannot guess what you owe the government. Our accountants take your total sales, subtract your purchases, and calculate the exact net tax you need to clear for accurate and timely payments.
Â
- Taking care of smaller composition scheme rules (CMP-08 and GSTR-4): If you run a smaller shop using flat-rate tax rules, we do not let you slip through the cracks. We handle the routine quarterly challans and prepare the comprehensive annual return for you.
Â
- Submitting the big year-end GSTR-9 and 9C summaries: Once the year ends, the tax department wants a giant master report matching all your past filings against your actual bank books. We run the deep audits to make sure nothing clashes.
Â
- Responding to departmental notices and resolving compliance flags: If a mismatch occurs, the tax department may issue a scrutiny letter or temporarily suspend your GST registration. We file prompt, professional replies to resolve these issues and restore your active status.
What documents must you provide to file accurate returns?
We simply cannot calculate your tax liability without looking at your actual operational records. You just hand over your paperwork, and we match your input tax credits so you never overpay the government. Before we start the filing process, you must pull these specific records from your daily operations:
- Outbound sales bills:
We need copies of every single tax invoice you sent to your buyers during the current billing cycle.
- Inbound purchase invoices:
We collect the bills you received from your suppliers. This step is critical because it allows us to claim your tax credits and lower your final bill.
- Debit and credit notes:
Provide any formal adjustments you made to previous invoices which can be customer returns or sudden pricing errors.
- Official bank statements
We look over your recent transaction history to cross-check your received payments against the invoices you issued to the public.
