GST Services Online for Every Stage of Your Business

GST is a tax on the supply of goods and services. It replaced VAT, service tax, central excise and several other indirect taxes from 1 July 2017. The law sits in the Central Goods and Services Tax Act, 2017 (CGST Act), the Integrated Goods and Services Tax Act, 2017 (IGST Act), the GST Act of each state and the rules made under them.

Paying the tax is only one part of GST. The law also asks you to register, issue proper invoices, report every sale, claim input tax credit (ITC) correctly, file returns on time and answer the department when it writes to you. GST services are the professional help that covers these duties, so you can run the business while the paperwork stays on track.

GST work comes in three kinds:

• One-time work: new registration, change of registration details, cancellation, revocation of a cancelled GSTIN and reply to a specific notice.
• Recurring work: GSTR-1 and GSTR-3B every month or quarter, ITC matching, the yearly GSTR-9 and GSTR-9C, and a fresh LUT every financial year for exporters.
• Advice on demand: GST rates and HSN codes, place of supply, reverse charge, e-invoice and e-way bills, refunds and appeals.

All GST filings happen on the common portal, gst.gov.in, run by the Goods and Services Tax Network (GSTN). Acts, rules, notifications and circulars are published on the CBIC GST website (cbic-gst.gov.in). We work only on these official systems, using your own login.

Think of GST as a set of duties that change as your business grows. Here is what the law asks at each stage, and which TaxCaller service covers it.

Most small businesses need only the first three rows in a normal year. Exporters add the LUT. Notices and cancellation come up less often, but they carry the tightest deadlines, so it helps to know about them before they arrive.

TaxCaller charges a professional fee for each GST service. The government charges almost nothing to file, but tax, interest and late fees are separate. The two are shown apart below.

Starting professional fee (+ GST), government fee extra

These are starting fees for the simplest case. Higher plans cover more invoices, more months or harder work. Our expert tells you the exact fee in writing before work starts. Every TaxCaller fee is + GST, because our service is itself a taxable supply.

What the government charges

GST has very few government filing fees. Most of what you pay the government is tax, and only defaults cost extra. Here is the split.

All government dues are paid by you directly from your own electronic cash ledger, using a challan created on the GST portal. They never pass through us, and they are paid at actual.

GST is one tax with four parts. Which part you charge depends on where the supply starts and where it ends, called the place of supply.

Delhi and Puducherry have their own legislatures, so they charge SGST, not UTGST. Exports and SEZ supplies are zero-rated under section 16 of the IGST Act.

Rates after the September 2025 reset. From 22 September 2025, most goods and services moved to two main rates, 5% and 18%, under Notification 9/2025-Central Tax (Rate) and the matching notifications for services. A 40% rate applies to a short list of luxury and sin items. A few special rates continue, for example on gold and precious stones. The old 12% and 28% slabs were largely removed.

Rates change only by notification. Check the rate for your HSN or SAC code before you price a new product or sign a contract. Our free tools page has a GST calculator for quick checks.

Many GST duties depend on your aggregate turnover. Under section 2(6), this is the total value of taxable, exempt, export and inter-state supplies of all your GSTINs under one PAN, across India, without the GST itself. These are the limits that matter most in November 2026.

Two points people often miss. First, the registration limit counts exempt sales too, so a business selling mostly exempt goods can still cross it. Second, once you are registered, every return is due even if your turnover later falls, until the GSTIN is cancelled.

After registration, you choose how you will pay and report GST. The choice decides your forms, your due dates and whether your buyers get ITC.

Composition tax rates are low, 1% for traders and manufacturers and 5% for restaurants, but you lose ITC and cannot charge GST to buyers. Section 10(2) and Notification 14/2019-Central Tax also bar some businesses, such as makers of ice cream, pan masala and tobacco products. Service providers use the separate section 10(2A) scheme at 6%.

QRMP cuts the number of returns from 24 to 8 a year. Tax is still paid every month, either by a fixed sum based on the last return or by working out the actual tax. If your B2B buyers want ITC monthly, you can upload their invoices through IFF in the first two months of the quarter.

Not sure which suits you? Our expert compares tax cost, ITC and paperwork on your actual numbers before you opt in. You can then move on to return filing under the chosen option.

Here are the GST dates a business tracks through the year. Dates fall in the month after the tax period unless the table says otherwise. The government extends a date only by notification, so always check the news section of gst.gov.in near a due date.

A practical rhythm: send sales data by the 5th and purchase data by the 10th. That leaves time to match ITC in IMS and GSTR-2B before GSTR-3B is due.

Good GST compliance is more than avoiding fines. It changes how buyers, banks and the department see your business.

• Your buyers get ITC. A business buyer can claim ITC only if your invoice shows in their GSTR-2B (section 16(2)(aa)). Late or wrong GSTR-1 filings cost them money, and soon cost you the customer.
• Lower tax cost. Correct ITC claims reduce the cash you pay. Missed claims after 30 November of the next year are lost for good.
• Loans and tenders. Banks, NBFCs and government buyers often ask for GSTR-3B and GSTR-1 copies and a clean filing record.
• Selling online and across states. E-commerce platforms and inter-state supplies of goods need an active GSTIN.
• Smooth exports. An LUT lets you export without blocking cash in IGST, and clean returns speed up refunds.
• Fewer notices. Most scrutiny notices come from mismatches between GSTR-1, GSTR-3B, GSTR-2B and the annual return. Matching them each month keeps them away.
• Fewer surprises. No blocked e-way bills, no surprise suspension of your GSTIN and no interest piling up in the background.

Keep these ready for the service you need. We confirm the exact list on the first call, because it changes with the type of business and premises.

Rule 26 asks companies to verify GST applications and filings with a Class 3 Digital Signature Certificate (DSC). Most other taxpayers can sign with an Aadhaar OTP (EVC). Share documents as clear PDF scans or photos. Our expert flags anything that looks likely to draw a query before it goes to the portal.

Every GST service at TaxCaller follows the same simple path. You deal with one expert from the first call to the filed acknowledgement.

1. Free first call. Fill in the "Talk to a GST Expert" form or call us. Our expert asks what has happened and which dates are close.
2. Right service, clear fee. We tell you which service fits, what is in scope and the fee, before any work starts. Our fee is charged + GST. Government dues are separate.
3. Documents online. You share documents by email or WhatsApp. We check them against the portal's rules and list anything missing.
4. Preparation. We draft the application, return, LUT or reply. For returns, we match your ITC with GSTR-2B and IMS first.
5. Your approval. You see the draft and the tax payable before anything is filed.
6. Filing and OTP. We file on gst.gov.in. You confirm with an Aadhaar OTP (EVC) or DSC, as the portal requires.
7. Proof. You receive the ARN, acknowledgement or filed return as a PDF for your records.
8. Follow-up. We track queries, notices and next due dates, and remind you before each one.

Everything happens online, so you do not need to visit our office or any GST office. Where an officer orders a physical check of your premises, we tell you what to keep ready.

Some timelines are set by law. Others depend on how fast documents come in and how the officer responds. Here is what to expect.

Our own turnaround is quick once documents are complete. We usually file within one to two working days for registration, LUT and routine returns. Notice replies take longer, because each one needs a reconciliation, and we agree a date with you on the first call.

GST defaults cost money in three ways: late fee, interest and penalty. The amounts below are as on November 2026.

Other consequences of not filing:

• A GSTR-3A notice, and then an assessment of your tax by the officer (sections 46 and 62).
• E-way bills blocked after two or more tax periods of missed returns (Rule 138E).
• Suspension and then cancellation of the GSTIN (section 29(2)).
• Your buyers lose ITC on your bills, which hurts business relationships.

Example: a regular GSTR-3B filed 10 days late costs ₹500 in late fee. If ₹1,00,000 of tax was also paid 30 days late, interest adds about ₹1,479. Late fee must be paid in cash. ITC cannot be used for it.

Every GST notice carries its own deadline. If the date passes, the officer can decide without hearing you. These are the notices businesses see most, with the time the law gives to respond.

Which demand section applies? For FY 2017-18 to FY 2023-24, demands are raised under section 73 (no fraud) or section 74 (fraud or suppression). From FY 2024-25, both cases fall under one section, 74A. The notice must be issued within 42 months from the due date of the annual return, and the order within 12 months after that. Where there is no fraud, paying the tax with interest within 60 days of the notice means no penalty.

If the order goes against you:

• First appeal: to the Appellate Authority in APL-01 within 3 months of the order, plus 1 month for sufficient cause. You pay the admitted tax and 10% of the disputed tax, capped at ₹20 crore under the CGST Act (section 107).
• Second appeal: to the GST Appellate Tribunal within 3 months of the appeal order, with a further 10% pre-deposit, also capped at ₹20 crore under the CGST Act (section 112). The tribunal was launched on 24 September 2025 and takes appeals online.

Our GST notice reply service handles the reply, the reconciliation behind it and the hearing.

Most GST trouble starts with small errors that repeat month after month. These are the ones we see most often.

• Address proof mismatch. The rent agreement, electricity bill and the address typed in REG-01 do not match. This is the top reason for registration queries and rejection.
• Missing the REG-03 reply. If the query is not answered within 7 working days, the application can be rejected.
• Claiming ITC not in GSTR-2B. Section 16(2)(aa) allows ITC only for invoices your supplier has reported. Claiming more invites a DRC-01C intimation or a notice.
• Wrong buyer GSTIN or B2B shown as B2C. Your buyer then loses ITC, and the fix has to be made through GSTR-1A or an amendment.
• Wrong place of supply. Charging CGST and SGST instead of IGST, or the other way round, means paying again and claiming a refund.
• Skipping nil returns. A nil return is still due. Late fee runs even when there is no tax.
• Not paying suppliers within 180 days. ITC must then be reversed with interest, under the second proviso to section 16(2).
• Forgetting the yearly LUT. Exports made without a valid LUT for that year may need IGST paid on them.
• Closing the business but not the GSTIN. Returns and late fees keep running until cancellation, and GSTR-10 is still due after it.
• Ignoring the portal. Notices are served on the portal and by email under section 169. Many owners see them only after the reply date has passed.

Each of these can be avoided with a monthly check. That is the main reason businesses hand GST to an expert rather than filing in a rush on the last day.

Registration is the start. These duties run every day after that, in the background of your business.

• Tax invoices. Each invoice must carry the details listed in section 31 and Rule 46: GSTIN of both parties for B2B sales, invoice number, date, HSN or SAC code, taxable value, rate and tax amount, and place of supply.
• E-invoice. If your aggregate turnover crossed ₹5 crore in a previous financial year, B2B invoices must be reported to the Invoice Registration Portal to get an IRN and QR code (Rule 48(4)).
• E-way bill. Goods worth more than ₹50,000 per consignment need an e-way bill before they move (Rule 138).
• ITC matching. Each month, accept, reject or keep pending your purchase invoices in IMS, then check GSTR-2B before claiming ITC. ITC on items listed in section 17(5), such as most motor cars and food, is blocked.
• Reverse charge. On some purchases, such as legal services from an advocate or goods transport from a GTA, you pay the GST instead of the supplier (section 9(3) and 9(4)).
• Records. Keep books and invoices for 72 months from the due date of the annual return for that year (section 36).
• Display. Show your GSTIN and certificate at your place of business (Rule 18).

Most of this is easier with good books. Our accounting and bookkeeping service keeps your ledgers GST-ready, so return filing becomes a monthly routine rather than a scramble.

The same law lands differently on each kind of business. Here is what usually matters most, and which service tends to fit.

If your work spans several of these, such as a shop that also sells online, the stricter rule applies. Our expert sets this out on the first call.

These changes come from CBIC notifications, GSTN advisories and the GST Council website. We list only what has been officially notified or announced, and we flag what is still a recommendation.

Already notified

• New registration, amendment and cancellation rules (from 1 November 2026). The CGST (Amendment) Rules, 2026, notified by Notification 05/2026-Central Tax dated 26 October 2026, revised REG-01 and substituted Rules 19 and 20. Most changes in registration details, other than the principal place of business, now take effect on submission. Where returns are filed, dues are paid and set conditions are met, such as monthly output tax within ₹2.5 lakh, the portal now cancels a REG-16 application itself and confirms it in REG-38.
• Rule 14B for online sellers. A seller registered in one state can register in another state using an e-commerce operator's warehouse as the place of business, if its tax on supplies to registered buyers stays within ₹2.5 lakh a month and the operator consents within 7 working days.
• Faster refunds. The officer must issue the refund acknowledgement or deficiency memo within 10 days instead of 15 (Rule 90). Otherwise, the application is treated as acknowledged.
• Finance Act, 2026 changes (from 1 November 2026). Notification 03/2026-Central Tax brought sections 153 to 155 of the Finance Act, 2026 into force. Post-sale discounts can now be given through a credit note, with the buyer reversing ITC (sections 15(3) and 34). Provisional refund of 90% now covers inverted duty claims (section 54(6)). The ₹1,000 minimum refund limit no longer applies to exports made with IGST paid (section 54(14)).
• GSTR-3B portal changes. GSTN advisories in early 2026 made the portal compute interest in Table 5.1 and required the tax liability breakup to be saved before filing. Auto-filled liability from GSTR-1 stays locked, so corrections go through GSTR-1A.
• Annual return for FY 2025-26. GSTR-9 and GSTR-9C opened on the portal on 8 October 2026 and are due on 31 December 2026. The ₹2 crore exemption continues.
• Notified for 1 April 2027. The same notification substitutes Rules 21A and 22 and adds a new Rule 23A from 1 April 2027: system-based suspension and cancellation for non-filing, and revocation of such cancellation on an application in REG-21 within 180 days.
• Three-year bar in action. Returns cannot be filed three years after their due date. GSTR-9 for FY 2022-23, due on 31 December 2023, cannot be filed after 31 December 2026.

Recommended by the 57th GST Council (8 October 2026), not yet law

• Waiver of late fee on GSTR-3B (returns under section 39(1)) for previous-year turnover up to ₹5 crore, if filed by the end of the month in which it was due.
• No show cause notice where the tax involved is below ₹10,000.
• Cut in the general penalty under section 125 from ₹25,000 to ₹10,000.
• Removal of arrest powers by omitting section 69, and a higher money threshold for prosecution, from ₹1 crore to ₹5 crore.

The Council's press release itself says that its recommendations take effect only through notifications, circulars or law amendments. We update this page as each one is notified.

GST is one law, but some parts change from state to state.

• Limits differ. Registration limits are lower in some North-Eastern and hill states, as shown in the thresholds table.
• One GSTIN per state. Under section 25, you need a separate registration in each state from which you supply. Each GSTIN is treated as a distinct person under section 25(4), with its own returns.
• Quarterly GSTR-3B dates. QRMP filers in states such as Maharashtra, Gujarat, Karnataka, Tamil Nadu and Telangana file by the 22nd. Those in states such as Uttar Pradesh, Delhi, Haryana, Punjab, Rajasthan, Bihar and West Bengal file by the 24th.
• Jurisdiction. Your GSTIN is allotted to either a central or a state tax office. Notices come from that office, and replies go to it on the portal.

TaxCaller works from Ghaziabad, Uttar Pradesh, and serves clients online across India. Since all GST work happens on the common portal, a business in Mumbai, Bengaluru or Guwahati gets the same service as one in Noida or Delhi. Where a hearing needs someone in person, we tell you in advance what that involves.

• One team for the whole GST journey. From the first registration to the final GSTR-10, the same team knows your history. You do not start from scratch for each notice or filing.
• Tax experts, reviewed content. Our tax experts handle the work. This page is reviewed by Abhinay Rai, Advocate, and every rule here is checked against official sources.
• Clear fees. Each service shows its fee. Our fee is + GST. Government fees and taxes are separate and paid by you directly at actual.
• Online, with your control. You approve every draft and confirm with your own OTP. Nothing is filed without you seeing it.
• Reminders before due dates. We track the calendar for you and ask for data early, not on the last day.
• Working since 2018. TaxCaller has helped businesses with tax and compliance work since 2018, from its office in Ghaziabad.

Doing GST yourself or with an expert

You can do every GST filing yourself on the portal. The government charges nothing for it. So when does an expert make sense?

Under section 48, you can authorise a GST practitioner to file on your behalf. Section 48(3) is clear, though: the responsibility for correct details stays with you, the registered person. So pick help that explains each return to you, shows you the tax before filing and keeps you in control of the OTP.
