Direct Answer
Exports are zero-rated under section 16 of the IGST Act: you either export under a LUT/bond without paying IGST and claim a refund of unutilised input tax credit, or pay IGST and claim a refund of the tax paid. Export invoices are reported in Table 6A of GSTR-1 with shipping-bill details, and for tax-paid exports the shipping bill itself serves as the refund application. Zero-rating refunds the whole chain's tax, unlike an exemption.
Calculation / Legal / Decision Framework
Use an invoice-led reconciliation: books → GSTR-1/1A → GSTR-2B → GSTR-3B → electronic credit/cash ledgers → payment. Classify every difference as timing, amendment, credit note, RCM, import, blocked/ineligible credit or error instead of forcing totals to match.
Six-step reproducible control
| Step | Control | What to record |
|---|---|---|
| 1 | Period / date | FY/AY/tax year, deposit date, sanction date, trade date or valuation date |
| 2 | Scope / eligibility | Taxpayer/product/instrument/category and governing source |
| 3 | Inputs | Amount, rate, unit, date and evidence source |
| 4 | Calculation | Reproducible formula / return / ledger working |
| 5 | Exception | Fact that changes or invalidates the answer |
| 6 | Action | Filing, payment, documentation, comparison or monitoring step |
Worked Example
If books show ₹10 lakh outward supplies but portal data shows ₹9.8 lakh, locate the invoice/timing/amendment reason. Correct the relevant return period rather than forcing a ₹20,000 adjustment without invoice evidence.
The worked numbers are illustrative unless identified as a current official value. Replace them with the actual dated rate, return, policy quote, sanctioned loan terms, transaction history or statutory input before acting.
Step-by-Step Practical Workflow
Step 1 — Freeze the governing period
Write the exact period at the top of the working: AY/FY, tax period, financial year, investment horizon, loan sanction date, policy year, trade date or scheme-rate quarter. This prevents an old rule or rate from being silently carried into a current article.
Step 2 — Identify the controlling source
Prefer the exact Act/rule/circular/Government notification/regulator page/exchange page/product document. A search result, aggregator, broker blog or social post can help discovery but should not override the primary source.
Step 3 — Reconcile the inputs
Match portal data, statements, contract notes, invoices, bank schedules, policy documents or tax records to your own working. Differences should be explained by cause—timing, classification, amendment, fee, tax, rounding or missing transaction—not hidden by a balancing entry.
Step 4 — Calculate the base case
Keep formulas visible. If a calculator is used, preserve inputs and the methodology date. A reviewer should be able to reproduce the result without guessing what the tool did.
Step 5 — Run an adverse case
Change the rate, return, cost, inflation, payment timing, filing position, liquidity assumption or tax eligibility. If a modest adverse change reverses the decision, that sensitivity is part of the answer.
Step 6 — Preserve the evidence
Store the source, calculation, transaction/filing proof and a short decision note. For YMYL topics, the review date matters almost as much as the publication date.
Common Mistakes
- Treating a keyword's number as an official current rate, limit or due date.
- Mixing periods, products or legal regimes because they use similar terminology.
- Publishing one calculator output without its input dates, units and assumptions.
- Using a secondary summary where an exact current regulator/Government source exists.
- Optimising a headline metric while ignoring cash flow, evidence and downside.
What to Keep in the Evidence File
- Exact official/regulator/Government/exchange source used.
- As-of/effective date.
- Calculation inputs and units.
- Relevant statements, invoices, contract notes, payslips, policy schedules, loan offers or tax records.
- Reconciliation of any portal/pre-filled value to underlying records.
- Filing/payment/transaction acknowledgement where applicable.
- A note of the main exception and adverse scenario.
Official Sources
Current Primary Sources
- GST Portal — Form GSTR-1 guidance: https://tutorial.gst.gov.in/userguide/returns/GSTR_1.htm
Why it matters: Invoice-level outward-supply reporting and amendments; use current portal due-date/calendar for the taxpayer's filing frequency. - GST Portal — Form GSTR-3B User Guide: https://tutorial.gst.gov.in/userguide/returns/GSTR3B.htm
Why it matters: GSTR-3B is a summary return; monthly due date ordinarily 20th, quarterly 22nd/24th as notified by State/UT; auto-population does not shift responsibility from taxpayer. - Finin2min Editorial Policy: https://finin2min.com/editorial-policy.html
