GST Filing Services in Hyderabad: GSTR-1 & GSTR-3B Monthly Filing

Hyderabad businesses file thousands of GST returns every month through the GSTN portal. GSTR-1 (sales report) is due the 11th. GSTR-3B (tax liability summary) is due the 20th. Missing either deadline triggers ₹500-₹5,000/day penalties. Missing both creates GST credit blocks and scrutiny risk.

Finding a GST filing service in Hyderabad that actively reconciles GSTR TwoB, flags mismatches, and files on time is harder than it looks. Many Hyderabad CAs treat GST filing as data entry: collect your sales and purchase figures, enter them, file the form. When ITC mismatches surface weeks later (or during GSTR Nine), the consultant is unreachable.

This guide explains what GST filing services in Hyderabad cover, what they cost, and how to choose one that stays ahead of deadlines instead of chasing penalties.

Why Hyderabad Businesses Need Dedicated GST Filing Support

GST Filing Complexity in Hyderabad

Hyderabad businesses file GST under Telangana state code 36. All supplies within Telangana (between Kondapur and Secunderabad, for example) attract CGST + SGST (9% each on taxable supplies). The moment you invoice a Maharashtra client or sell to a Karnataka retailer, the same 18% flows as IGST to the destination state. That switching between intra-state and inter-state treatment matters significantly for three types of Hyderabad businesses:

IT and software exporters operating out of HITEC City and Madhapur export services to clients abroad. These supplies are zero-rated. The firm files a Letter of Undertaking (LUT) and does not charge GST on export invoices, but simultaneously accumulates input tax credit on domestic purchases. That accumulated credit has to be refunded under Section 54, and the refund claim process is document-heavy and requires active portfolio tracking.

Pharma and medical device distributors in Hyderabad's Nacharam and Azamabad belt deal with a complex mix of GST-exempt medicines (nil-rated under Schedule 1), 5% GST items (most medicines), 12% items, and 18% items for certain devices. A single HSN classification error gets multiplied across thousands of line items in a wholesale operation. ITC reversal requirements under Rule 42 add another layer.

E-commerce and D2C businesses in HITEC City and Financial District face specific April 2026 e-invoice compliance rules and intra-state IGST treatment exceptions. These rules change quarterly; a filing service that does not proactively notify you of changes will leave your compliance outdated.

A filing service that treats all GST returns the same way (collect data, enter figures, file) misses these nuances. By the time a GSTR Nine or notice arrives, accumulated mismatches have already accrued.

What GST Filing Services in Hyderabad Actually Do (Month-to-Month)

Here is what a competent GST filing service should be doing for a Hyderabad business between the 1st and 20th of every month:

Between 1st and 11th: Collect your sales register data and verify GSTR-1 preparation. For monthly filers, GSTR-1 is due on the 11th. The filing service should flag any B2B invoices that lack the buyer's GSTIN, identify nil-rated and exempt supplies separately, and confirm HSN/SAC codes are correctly applied. For an IT firm, this means verifying that export invoices are marked "zero-rated" with the LUT reference.

On or around the 14th: Download your GSTR TwoB from the GST portal. This auto-generated statement shows ITC available from suppliers who have filed their GSTR-1 for the prior period. Any filing service that is not downloading and reviewing GSTR TwoB every single month is not reconciling. They are filing blindly.

Between 14th and 18th: Reconcile GSTR TwoB against your purchase register. Every line that appears in your books but not in GSTR TwoB represents a supplier who has not filed their return. That ITC cannot be claimed under the current hard-block regime. The filing service must identify these gaps, chase the supplier, or make the decision to defer the claim.

By the 18th: Prepare your GSTR ThreeB with the reconciled figures. This includes computing net ITC available, applying any reversal obligations (Rule 37 for payments not made to suppliers within 180 days), calculating the cash and credit ledger utilisation, and determining the final tax payable.

By the 20th: File GSTR ThreeB and make the tax payment. No exceptions. A missed 20th means ₹50/day late fee (₹25 CGST + ₹25 SGST) for nil-tax returns, and 18% interest per annum on unpaid tax for returns where tax is due.

Ongoing: Annual GSTR Nine preparation, LUT renewal for exporters, notice responses, e-invoice compliance for businesses above ₹5 crore turnover, and e-way bill support for goods movement.

Any GST filing service in Hyderabad that cannot tell you your ITC utilization for last month has not actually reviewed your books.

GST Filing Costs in Hyderabad: What Is Normal, What Is Suspicious

Pricing for GST filing services in Hyderabad varies based on business complexity, filing frequency, and turnover:

Basic GSTR-1 and GSTR-3B filing (monthly filer, single GSTIN, turnover below ₹1 crore, no reconciliation): ₹1,500 to ₹3,000 per month. This covers data collection from your tally or accounting software, GSTR-1 preparation, GSTR-3B filing, and tax payment. It does not include GSTR TwoB reconciliation, notice responses, or advisory.

Full compliance with GSTR TwoB reconciliation (turnover ₹1-5 crore, moderate B2B transactions, single GSTIN): ₹4,000 to ₹8,000 per month. This is the range where a filing service is actively matching your purchase register to GSTR TwoB, identifying supplier filing gaps, managing ITC accurately, and preparing GSTR ThreeB from reconciled data. For a Kondapur IT firm with 15-20 vendors and a handful of B2B clients, this is the minimum adequate scope.

Complex compliance (turnover ₹5-20 crore, pharma or e-commerce, multiple GSTINs, or businesses above e-invoice threshold): ₹8,000 to ₹18,000 per month. This tier typically includes e-invoice management, e-way bill support, annual GSTR Nine and GSTR NineC preparation, and proactive advisory on ITC optimization.

Large businesses (turnover above ₹20 crore, multi-state GST structure, or ongoing refund claims): ₹20,000 to ₹50,000 per month or higher for full-service compliance. The refund cycle alone for an IT exporter with a large accumulated IGST credit can justify ₹25,000 or more in filing fees.

Red flag: Any Hyderabad CA quoting below ₹1,000/month for a business with B2B transactions is offering data entry, not compliance. That price point almost always means the consultant is only looking at your sales summary and entering GSTR ThreeB figures without GSTR TwoB reconciliation. Accumulated ITC mismatches from this approach surface in GSTR Nine and create scrutiny exposure.

How to Choose a GST Filing Service in Hyderabad

Step 1: Verify the Consultant's GSTIN

A practicing CA or tax consultant in Hyderabad whose aggregate turnover exceeds ₹20 lakh must be GST-registered themselves. Their GSTIN should start with 36 (Telangana state code). If they cannot tell you their GSTIN off the top of their head, or they are not registered themselves, that is a data point about their own compliance culture.

Step 2: Ask About GSTR TwoB Reconciliation

This is the single most revealing question. Many Hyderabad filing practices include only GSTR-1 and GSTR-3B preparation in the base fee, with GSTR TwoB reconciliation charged separately or not offered at all. Since the April 2026 ITC hard block, filing GSTR ThreeB without first reconciling against GSTR TwoB means your return may be rejected at submission. Reconciliation must be explicitly included in writing in your engagement letter.

Step 3: Confirm the Filing Reminder Workflow

A well-run practice has a documented reminder workflow: WhatsApp or email by the 5th requesting data, escalation on the 8th if data is not received, and a clear protocol for what happens if a deadline is missed due to your data not being provided. If the consultant does not have a clear answer to this question, you will be calling them on the 19th asking if GSTR ThreeB was filed.

Step 4: Ask About Annual GSTR-9 Preparation

Annual GSTR-9 is the comprehensive GST return reconciling all 12 monthly filings. A competent practice with active clients will have filed dozens every year. If the answer is vague ("oh we handle many clients"), press for a specific number. Pharma distributors should specifically ask about experience with exempt-and-taxable supply reconciliation in GSTR-9.

Step 5: Ask What Happens When a Notice Arrives

A notice under Section 61 (scrutiny of returns), Section 73 (demand for non-payment), or Section 74 (suspected fraud) has a response deadline specified in the notice (often 15 to 30 days). What happens when a notice arrives for one of their Hyderabad clients? Who drafts the response? Is it the CA directly, or a junior who drafts for sign-off? How long does turnaround take? A practice that cannot answer clearly is one where your notice will sit in a queue.
