    Key takeaways
    • IT / SaaS Companies filers: GSTR-1 by the 10th, GSTR-3B by the 20th, GSTR-9 by 31 December — miss and pay ₹50/day + 18% interest.
    • ITC eligibility for IT / SaaS Companies is dictated by GSTR-2B; blocked credits under Section 17(5) must be reversed monthly.
    • Correct HSN/SAC and place-of-supply are the two errors IT / SaaS Companies businesses lose most ITC on.
    • E-invoicing is mandatory above ₹5 Cr turnover; missing IRN blocks buyer's ITC.
    • Taxpex files 3 days early, CA-signs every return and defends notices on filed periods free of charge.

    Definition

    GSTR-1

    Monthly outward supplies return (or IFF under QRMP) listing every invoice, credit note and export raised by the taxpayer.

    Definition

    GSTR-3B

    Monthly summary return declaring supplies, ITC and net tax payable — the return that settles GST liability with the government.

    Definition

    Input Tax Credit (ITC)

    GST paid on inward supplies used for business; claimable only when the invoice appears in GSTR-2B and payment is made within 180 days.

    Definition

    Reverse Charge (RCM)

    Situations where the recipient (not the supplier) pays GST — common for import of services, GTA and lawyer fees relevant to many sectors.

    Why GST return filing matters for IT / SaaS Companies

    • LUT renewal on 1 April — no LUT means 18% IGST upfront on exports.
    • FIRC and BRC are mandatory for RFD-01 refund claims.
    • Foreign SaaS RCM declaration in 3B 3.1(d) is non-negotiable.
    • Multi-state GSTINs (dev centre in Bangalore, sales office in Delhi) need separate returns.
    • ESOP allotment triggers cross-charge GST implications.

    When do I need reverse GST?+

    When a supplier gives you a GST-inclusive price and you need to break it into base + GST for invoicing or ITC reconciliation.

    How is CAGR different from absolute return?+

    Absolute return ignores time; CAGR normalises the return to a per-year compounded rate — the standard measure for comparing multi-year returns.

    What if I miss a GST deadline?+

    ₹50/day late fee (₹20 for nil returns) plus 18% p.a. interest. After 6 months of non-filing, GSTIN can be cancelled.

    Do I need GST to register?+

    GST is mandatory only if your turnover exceeds the GST threshold. Otherwise PAN is enough.
