Why GST SOPs Matter for Tech Companies

If you’re running an IT services company or software business in India, chances are you’re juggling client deadlines, export invoices, and foreign SaaS subscriptions — all while trying to stay GST compliant. Sound familiar?

Here's the thing: missing even one step in your GST compliance (like filing a Letter of Undertaking on time or accounting for import services under Reverse Charge) can invite penalties, notices, and ITC rejections.

This is where a clear, practical GST Standard Operating Procedure (SOP) becomes your secret weapon.

In this blog, we’ll walk you through sector-specific GST SOPs for IT and software companies — written in plain English, with real-world relevance.

Who Is This For?

This guide is perfect for:

• IT Services Providers

• Software Development Firms

• Tech Startups & SaaS Companies

• Businesses with exports and foreign subscriptions

Whether you're a freelancer scaling up or a mid-size tech LLP, these SOPs will help streamline your GST game.

1. GST SOP for Invoicing & E-Invoicing

Why it matters: Wrong invoice formats or late e-invoice generation can delay ITC for clients and attract notices.

Step-by-Step:

• Raise invoices with correct SAC (e.g., 998313 for Software Dev).

• For B2B, generate e-invoices with IRN and Ack No. using the NIC portal or your ERP.

• For exports, mark the invoice “Under LUT without payment of IGST”.

• Maintain a proper e-invoice register (Date, GSTIN, IRN, Export flag).

Pro Tip: Reconcile your e-invoice data with GSTR-1 every month to avoid mismatches.

2. SOP for Export of Services & LUT Compliance

Why it matters: Forgetting to file LUT = You pay GST on exports and claim refund later. Not ideal.

What to Do:

• File LUT before March 31 every year on the GST Portal.

• Add attachments: Previous LUT, Authorization Letter, DSC.

• Mention LUT details on export invoices.

• Keep FIRC/BRC as proof of foreign exchange received.

Pro Tip: Set a calendar reminder in March to avoid missing your LUT renewal.

3. SOP for Input Tax Credit (ITC) – Tools, Subscriptions & Expenses

Why it matters: ITC is your money. Claiming it right = saving lakhs over time.

Your ITC Checklist:

• Ensure vendors upload invoices correctly (watch out for mismatches in GSTR-2B).

• Classify purchases:

  • Eligible ITC: Laptops, rent, cloud subscriptions

  • Blocked ITC: Food, gifts, employee travel (per Sec 17(5))

• Maintain a clean RCM ledger for imported services.

• Review ITC monthly and reconcile with GSTR-2B.

Pro Tip: Use tools like Tally, Zoho Books, or ClearTax for auto-matching ITC.

4. SOP for Reverse Charge Mechanism (RCM) – Imported Services

Why it matters: IT companies often miss GST on foreign tools (like AWS, Zoom, or Adobe). This triggers audit issues.

Stay Compliant:

• Maintain an Import Register with:

  • Vendor, Invoice No., Value (in INR), Service Type

• Use RBI exchange rate on invoice date.

• Calculate GST @18% and pay using PMT-06 Challan.

• Claim this GST back in the same GSTR-3B return.

Pro Tip: RCM applies even if the foreign vendor doesn’t charge GST — it’s your duty as the importer.

5. Monthly & Annual Return Filing SOP

Monthly:

• File GSTR-1 by 11th (outward supplies)

• File GSTR-3B by 20th (tax payment + ITC claim)

Annually:

• File GSTR-9 (Annual Return)

• If turnover > ₹5 Cr, file GSTR-9C (Audit Reconciliation)

Pro Tip: Don’t wait till December. Start annual reconciliations in October using a proper checklist.
