Returns under GST for CA Intermediate: Chapter Guide

GST returns are periodic statements that registered persons file under the CGST Act, 2017 to report sales, purchases, tax and credit. To solve questions, identify the type of person, pick the right return, check the due date, then work out tax, interest and late fee step by step, and state your conclusion.

What this chapter covers

This chapter covers how a registered person reports and pays GST. You study the main returns: GSTR-1 (outward supplies), GSTR-2B (auto-drafted credit statement), GSTR-3B (summary return with payment), the annual return GSTR-9 and the reconciliation statement GSTR-9C. You also study the returns for special persons: composition taxpayers, non-resident taxable persons, Input Service Distributors, and those who deduct or collect tax at source.

The chapter ties together almost everything else in GST. Your supply, value and rate knowledge decides what goes in GSTR-1. Your input tax credit knowledge decides what you claim in GSTR-3B. Your payment and registration knowledge decides when, and by whom, a return must be filed. Think of returns as the place where all other chapters finally appear on one form.

Questions in this chapter are usually of three kinds. First, factual MCQs on which return, who files it and by when. Second, small case-based questions on late fee or interest. Third, short written answers on matching of credit or annual return rules. Due dates and thresholds can be changed by notification, so learn the rule and the logic, and follow the dates in your study material for your attempt.

Returns is a compact chapter with many clear, fact-based points, which makes it good for MCQs, where there is no negative marking and no reasoning is needed. It also gives you easy written marks, because interest and late fee questions follow a fixed method that earns step marks when you show the working. Since it links to input tax credit, time of supply and payment of tax, revising it also strengthens those chapters. Students who learn the returns as a connected flow, not as a list of form names, tend to answer faster and more accurately.

Returns: topics in the order to study them

  1. 1Returns Under GST: Types and Basic ProvisionsStart with the map: which return is for which person, and the basic rules in the CGST Act, 2017, so every later form has a place.
  2. 2GSTR-1: Details of Outward SuppliesSales are reported first, and they feed the buyer's credit, so this is the natural starting point of the flow.
  3. 3GSTR-2A, GSTR-2B and Input Tax Credit MatchingYour sales appear in the buyer's statement, so you now see the credit side. Reflection of the supplier's details in GSTR-2B is one condition for credit. The other Section 16 conditions must also be met: tax invoice or debit note, receipt of the goods or services, tax paid to the government, and the return filed.
  4. 4GSTR-3B: Monthly and Quarterly Summary ReturnHere outward tax and eligible credit meet and tax is paid, so you need GSTR-1 and GSTR-2B clear before it.
  5. 5Composition, TDS, TCS and ISD ReturnsThese are special-person returns. They are easier once you know the regular returns to compare them with.
  6. 6Annual Return GSTR-9 and Reconciliation GSTR-9CThe annual return sums up the whole year's monthly returns, so study it after you know each monthly return.
  7. 7Late Fee, Interest, Nil Returns and Return ComplianceEnd with consequences of default, which apply to every return above and are best learned last for numerical practice.

How to prepare Returns

Learn this chapter as one flow from sale to annual return, then add dates, penalties and numbers. Work in short sessions that suit articleship days, and use your phone for table-style revision.

  1. Draw a one-page chart with columns: return, who files, what it reports, and due date. Fill it from your study material and keep it updated for your attempt.
  2. Read the section behind each return (Sections 37, 38, 39 and 44 of the CGST Act, 2017) and write in one line what each section requires.
  3. Trace one sample invoice from the seller's GSTR-1 to the buyer's GSTR-2B and then into GSTR-3B. This makes credit matching easy to understand.
  4. Practise interest and late fee questions with a fixed layout: state the due date, the actual date, the days of delay, the rate or per-day amount, then the final figure.
  5. Solve MCQs by topic and look for traps in wording: monthly or quarterly, turnover limit, who files, and which return a threshold applies to (for example, the limit for GSTR-9 and the limit for GSTR-9C are different).
  6. In written answers use provision, facts, conclusion. Name the return, apply the rule to the facts given, and end with a clear answer.
  7. In the last week, revise only your chart, your list of thresholds and your error log of past mistakes.

Common mistakes in Returns

  • Mixing up GSTR-2A and GSTR-2B

    Fix: Remember: 2B is fixed for a month and is the statement you check when claiming credit; 2A keeps updating. Link 2B with Section 16(2)(aa): credit is available only if the supplier has furnished the details in GSTR-1/IFF and they are communicated to you in GSTR-2B. Reflection in 2B is one condition. The other Section 16 conditions must also be met: tax invoice, receipt of the goods or services, tax paid to the government, and the return filed.

  • Confusing the return with the payment of tax

    Fix: Tax must be paid by the due date of the return. Filing without paying the cash liability still attracts interest on the unpaid tax.

  • Applying the wrong due date or frequency to special persons

    Fix: Keep your chart of persons, forms and dates. In an answer, first name the person type, then the return.

  • Wrong day count in interest and late fee

    Fix: Count from the day after the due date to the date of payment or filing. Show each step: days, rate, amount.

  • Treating GSTR-9C as filed by everyone

    Fix: Note the condition: GSTR-9C is a self-certified reconciliation statement, filed only by taxpayers whose aggregate turnover exceeds the notified limit, currently ₹5 crore for the years notified. Check the notification for the relevant year. Do not mix this limit with the optional-filing limit for GSTR-9 (₹2 crore for specific notified years) or with the QRMP limit.

  • Skipping nil returns and applying zero consequence

    Fix: Remember that a nil return is still a return. Delay leads to late fee, though at a lower rate.

Last-day revision: Returns

  • GSTR-1 reports outward supplies under Section 37; GSTR-3B is the summary return with payment under Section 39.
  • GSTR-2B is a static auto-drafted credit statement; GSTR-2A is dynamic and changes as suppliers file.
  • Section 16(2)(aa) allows credit only if the supplier has furnished the invoice or debit note details in GSTR-1 or IFF and they are communicated to you in the statement under Section 38 (GSTR-2B). This is one condition. The other Section 16 conditions must also be met: tax invoice or debit note, receipt of the goods or services, tax paid to the government, and the return filed.
  • Composition taxpayers pay tax quarterly through CMP-08 and file GSTR-4 annually. GSTR-9A was earlier the annual return for composition taxpayers, but it was discontinued from FY 2019-20.
  • TDS return is GSTR-7 and TCS return is GSTR-8; ISD return is GSTR-6.
  • Non-resident taxable persons file GSTR-5; OIDAR service providers outside India file GSTR-5A.
  • The QRMP scheme is optional. It is available to registered persons who are required to file GSTR-1 and GSTR-3B and whose aggregate turnover in the preceding financial year was up to ₹5 crore. Those who opt in file GSTR-1 and GSTR-3B quarterly and pay tax monthly through PMT-06. They may use the optional IFF to report supplies for the first two months of the quarter.
  • Annual return GSTR-9 is under Section 44. For certain specific years, filing GSTR-9 was made optional by notification for taxpayers with aggregate turnover up to ₹2 crore. This is not a general rule for every year, so check the notification for the relevant year in your question.
  • GSTR-9C is a self-certified reconciliation statement. It is filed only by taxpayers whose aggregate turnover exceeds the notified limit, currently ₹5 crore for the years notified. Check the notification for the relevant year. This is a different limit from the QRMP limit, even though both figures are ₹5 crore. Since FY 2020-21, certification by a CA/CMA is no longer required.
  • Late fee under Section 47 is a per-day amount under the CGST Act, with an equal amount levied under the SGST/UTGST Act. No IGST late fee applies. It has a maximum cap, so check the rates and cap against the notification for your attempt.
  • Interest on late payment of tax under Section 50 is 18% per annum, counted from the day after the due date to the date of payment. For a delayed GSTR-3B, interest under the proviso to Section 50(1) is charged on the net cash tax liability, meaning the amount payable after input tax credit is utilised. This proviso applies retrospectively from 1 July 2017. A higher rate of 24% per annum applies to undue or excess input tax credit claimed and utilised, and to undue or excess reduction in output tax liability. Interest is not charged on input tax credit wrongly availed but not utilised.
  • Nil returns must still be filed, and the late fee for them is lower than for returns with tax.
  • Due dates and limits can be changed by notification, so confirm them against the study material for your attempt.

Returns: frequently asked questions

Which GST returns are most important for CA Intermediate?

Focus first on GSTR-1, GSTR-2B and GSTR-3B, then GSTR-9 and GSTR-9C. Composition, TDS, TCS and ISD returns are shorter, but they give easy MCQ marks.

Do I need to memorise due dates?

Learn the main dates and the logic behind them, such as which returns come early in the month and which are quarterly. Use the chart in your study material for your attempt, because dates can change by notification.

How are interest and late fee questions solved?

Find the due date and the actual date, count the days of delay, and then apply the per-day late fee or the interest rate. Show each step, since step marks are given in written answers.

Is GSTR-9C required for every taxpayer?

No. GSTR-9C is a self-certified reconciliation statement, and it is filed only by taxpayers whose aggregate turnover exceeds the notified limit, currently ₹5 crore for the years notified. Check the notification for the relevant year. Certification by a CA/CMA is no longer required. Read the turnover condition in the question carefully before saying it applies.
