GST Return Filing in Karnataka

Stay GST-Compliant Without Slowing Down Your Karnataka Business

Karnataka is among India's top contributors to GST collections, powered by Bengaluru's software, biotech, aerospace and start-up ecosystem, Mysuru's silk and sandalwood trade, Ballari and Hosapete's steel and mining belt, coffee estates across Kodagu and Chikkamagaluru, the Hubballi-Dharwad commercial corridor, and Mangaluru's port-led trade. With this much activity, the GST department's data matching is sharp — an unfiled or mismatched return gets noticed quickly.

Whether you are a software exporter issuing hundreds of invoices, a retailer in Chickpet, or a manufacturer in Peenya, your GSTR-1 and GSTR-3B must be right and on time. SetupFiling.in's Chartered Accountants take over the monthly or quarterly routine, so you do not have to track due dates or wrestle with the portal. Starting out without a GST number? We can register your business for GST online in a few days and move straight on to filing.

How We File Your GST Returns in 5 Easy Steps

  1. Select Your Plan

    Pick the 3-month, 6-month or 12-month plan and pay safely through the Razorpay link on the plan card.

  2. Upload Your Data

    Send your invoices or sales and purchase registers through WhatsApp or email when the period closes.

  3. Expert Checks and Matching

    A Chartered Accountant reconciles purchases with GSTR-2B, spots mismatches, and confirms the credit you can claim.

  4. Approve the Numbers

    We share a simple summary showing sales, ITC and tax payable. You approve it and pay any cash balance.

  5. We File and Send Proof

    GSTR-1 and GSTR-3B are filed before the deadline, and you receive filed copies and acknowledgements.

The Cost of Late or Missed GST Returns

Filing late costs money and credibility. A daily late fee applies (₹50 per day for regular returns and ₹20 per day for nil returns, within the statutory cap) along with 18% yearly interest on tax paid late. Continued default can block e-way bills, affect your buyers' ITC and invite department action, including cancellation of your GSTIN.

Many Bengaluru service exporters also need a Letter of Undertaking to export services without IGST, and growing businesses often need to update GST registration details such as address or directors. If you are winding up, we can also manage GST registration cancellation, and small traders can explore the Composition Scheme for simplified tax payment.

Frequently Asked Questions

When are GST returns due in Karnataka?

Monthly filers submit GSTR-1 by the 11th and GSTR-3B by the 20th of the following month. Under QRMP, GSTR-1 is due on the 13th after the quarter ends and GSTR-3B on the 22nd for Karnataka taxpayers.

What does GST return filing cost in Karnataka?

Our plans cost ₹1,500 for 3 months, ₹2,500 for 6 months and ₹4,500 for 12 months of GSTR-1 and GSTR-3B filing, each covering up to 200 invoices and currently at 50% off.

Is it compulsory to file GST returns when there is no turnover?

Yes. Registered taxpayers must file nil returns for periods without transactions. Skipping them leads to late fees and may eventually cause cancellation.

How much is the late fee on GST returns?

The late fee is ₹50 per day for regular returns and ₹20 per day for nil returns, up to the prescribed maximum, and interest at 18% per year is charged on any unpaid tax.

What do the GST return plans include?

Every plan includes CA-assisted GSTR-1 and GSTR-3B filing for 3, 6 or 12 months with up to 200 invoices per period. GSTR-9 annual returns, new registrations and other services are charged separately.

I run an IT company in Bengaluru. Can you handle export invoices?

Yes. We report export invoices and zero-rated supplies in GSTR-1 and GSTR-3B correctly, and can also help you obtain an LUT so you can export services without paying IGST upfront.

Can I file GST returns for earlier months I forgot?

Yes. Pending returns can be filed with applicable late fee and interest. We review your account, calculate dues and file the backlog so your GSTIN stays active.

What is the GST state code for Karnataka?

Karnataka's GST state code is 29. A Karnataka GSTIN begins with 29, followed by the PAN, an entity number, the letter Z and a check digit.

Do you serve cities outside Bengaluru?

Yes. Our filing process is fully online, so businesses in Mysuru, Mangaluru, Hubballi, Belagavi, Kalaburagi and every other Karnataka location can use it through WhatsApp and email.
