GST Advisory

GST Advisory: complete guide

Introduction

Goods and Services Tax touches almost every commercial decision a business makes: how a contract is written, where an invoice is raised from, which rate applies to a product, whether input tax credit can be claimed on a purchase, and how a transaction with a related party or an overseas customer should be treated. The law is spread across the Central Goods and Services Tax Act, 2017, the Integrated Goods and Services Tax Act, 2017, the state GST laws, the GST rules, and a steady flow of notifications, circulars, clarifications and court rulings. Getting a single position wrong can mean tax, interest and penalty years later, after the money has already been spent.

GST advisory is professional guidance on how GST applies to your specific business, transactions and documents. It is different from routine return filing. Filing is about reporting what has already happened. Advisory is about deciding the correct treatment before or while it happens, so that the returns you later file are right and defensible. It covers questions such as classification and rate, place of supply, time and value of supply, eligibility of input tax credit, exports and zero-rated supplies, reverse charge, registration structure across states, and the GST impact of new business models.

The GST framework has also changed substantially since it began. Rate structures have been rationalised, compensation cess has been phased out on most goods, invoice management and e-invoicing requirements have widened, returns have become more automated and locked, and the department now uses data analytics to compare your returns with your suppliers' filings, e-way bills and income tax records. A position that went unnoticed a few years ago may now be flagged automatically. Advisory helps you take positions that are supported by the law and documented properly from the start.

Our team of chartered accountants and GST professionals studies your facts, reviews the relevant provisions and rulings, and gives you clear written guidance on what to do and why. Where the law is genuinely unsettled, we explain the options, the risk attached to each, and the documents you should keep. We do not promise outcomes, but we help you make informed decisions and avoid avoidable disputes.

Who Needs It

GST advisory is useful for any registered business, but it is especially valuable in the following situations:

• Businesses starting or changing operations. A new product line, a new state, a new warehouse or a shift from goods to services can change your registration needs, rates and credit position.
• Businesses unsure about classification. Products and services that sit between two tariff headings or service codes, such as composite products, food items, software, packaged goods or bundled services, often attract disputes about the correct rate.
• Exporters and service providers dealing with overseas clients. Whether a supply qualifies as an export of services, whether to export under a letter of undertaking or with payment of tax, and how to claim refunds all need careful handling.
• E-commerce sellers and operators. Tax collection at source, place of supply for online sales, and registration in multiple states raise specific questions.
• Companies with group or related-party transactions. Supplies between distinct persons, such as branches in different states with the same PAN, and transactions between related parties, have special valuation rules and may require cross-charge or Input Service Distributor arrangements.
• Real estate, construction and infrastructure businesses. Rates, credit restrictions and the treatment of development rights and works contracts are complex and fact-specific.
• Businesses facing large input tax credit mismatches. Differences between the credit you claim and what appears in your auto-drafted statements need to be understood and resolved before they turn into notices.
• Businesses planning restructuring. Mergers, demergers, slump sales, transfer of a business as a going concern and changes in constitution all have GST consequences.
• Startups and growing businesses. Founders who want to set up GST correctly from the first invoice, rather than fix it after a notice, often use advisory early.

Key Benefits

• Correct tax treatment from the start. Advice before you sign a contract or launch a product means invoices, rates and credit claims are right from day one.
• Lower risk of notices and demands. Positions taken with proper reasoning and documentation are easier to defend if the department raises a query.
• Better use of input tax credit. Many businesses either miss eligible credit or claim credit that is blocked. Advisory helps you claim what the law allows and avoid what it does not.
• Clarity on rate changes. When rates or exemptions change, we help you understand which supplies are affected and from what date, including treatment of advances and supplies that straddle the change.
• Cash flow planning. Choosing the correct export route, reverse charge treatment and refund strategy can significantly reduce the working capital locked up in GST.
• Well-drafted contracts. GST clauses in contracts, such as who bears the tax, how rate changes are handled and how credit is protected, avoid commercial disputes with customers and vendors.
• Informed decisions on advance rulings. Where the issue is significant and unclear, we help you decide whether seeking an advance ruling is worthwhile and how to frame the application.
• Written opinions for your records. A reasoned written note supports your position with auditors, investors, due diligence teams and the department.

Advisory compared with return filing. Return filing records the tax position after the month closes. Advisory decides what the tax position should be. A business can file every return on time and still accumulate large exposure if the underlying treatment is wrong, for example by applying a lower rate to a product or by claiming credit on items that the law blocks. Many of our clients combine monthly filing with periodic advisory reviews so that both the numbers and the positions behind them are sound.

How advisory works in practice. Most engagements begin with a specific question, such as "what rate applies to this product" or "is this supply an export". We collect the facts and documents, study the law, and give a written answer with the reasons. Larger engagements, such as a health check of the full GST position or advice on a restructuring, involve a review of returns, contracts and books over a period and a report with findings and corrective steps.

Eligibility and Legal Requirements

There are no formal eligibility conditions to take GST advisory. Any business, whether registered or planning to register, can seek it. The advice itself, however, is based on the legal framework, which includes:

• The Central Goods and Services Tax Act, 2017, the state and union territory GST Acts, and the Integrated Goods and Services Tax Act, 2017 for inter-state supplies, imports and exports.
• The GST rules, which cover registration, valuation, input tax credit, invoicing, returns, refunds and e-way bills.
• Rate notifications and exemption notifications issued on the recommendations of the GST Council, along with the classification rules based on the customs tariff and the scheme of classification of services.
• Circulars and clarifications issued by the Central Board of Indirect Taxes and Customs, which explain the department's view on specific issues.
• Advance rulings by the state Authorities for Advance Ruling and appellate authorities. These bind only the applicant and the jurisdictional officer, but indicate how an issue may be viewed.
• Judgments of High Courts and the Supreme Court, which interpret the law and can override departmental positions.

For an advance ruling, the applicant must be registered or seeking registration, and the question must relate to a matter permitted under the law, such as classification, applicability of a notification, time and value of supply, admissibility of input tax credit, liability to pay tax, or whether a particular activity is a supply. Advance ruling cannot be sought on a question already pending or decided in proceedings involving the applicant.

GST law changes frequently through notifications and circulars. Our advice is based on the law in force at the time it is given, and we recommend a fresh check before acting on it later.

Step-by-Step Guide

1. Initial discussion. We understand your business, the question you need answered, and the decision that depends on it, such as pricing, a contract or a filing.
2. Fact collection. We request the relevant documents, such as contracts, purchase orders, invoices, product descriptions, technical literature, process flows and previous returns.
3. Clarifying the facts. GST outcomes often depend on small details. We ask follow-up questions about how goods move, who receives services, where the contract is signed and who bears costs.
4. Identifying the issues. We set out the specific legal questions, such as classification, place of supply, time of supply, valuation or credit eligibility.
5. Legal research. We study the Acts, rules, notifications, circulars, advance rulings and court decisions that apply to those questions.
6. Analysis of options. Where more than one view is possible, we analyse each, with the supporting and opposing arguments and the risk attached.
7. Draft advice. We prepare a written note with our conclusions, reasons, assumptions and the documents you should keep.
8. Discussion and clarification. We walk you through the advice and answer follow-up questions from you, your accounts team or your auditor.
9. Implementation support. We help you apply the advice, for example by updating invoice formats, rate masters in billing software, contract clauses or credit tracking.
10. Final note and follow-up. We issue the final advice and, where useful, flag future events such as rate reviews or pending court cases that may require the position to be revisited.

Documents Checklist

For a specific transaction or question:

• A short description of the question and the business decision it affects
• Copies of contracts, agreements, quotations or purchase orders
• Sample invoices issued or received
• Product descriptions, technical specifications, catalogues or process notes for classification questions
• Details of the parties involved, their locations and their GST registration status

For an input tax credit question:

• Purchase invoices and the nature of the goods or services bought
• Details of how the purchase is used in the business
• Extracts from the auto-drafted input tax credit statements for the relevant months

For exports and overseas transactions:

• Export contracts or service agreements with overseas clients
• Proof of receipt of payment in foreign exchange
• Shipping bills, letters of undertaking or refund filings, where relevant

For a GST health check or review:

• GST registration certificates for all states
• Returns filed for the period under review
• Sales and purchase registers and the general ledger
• Previous notices, replies and orders, if any
• Details of e-way bills and e-invoices, where applicable

For restructuring advice:

• Draft scheme, business transfer agreement or term sheet
• List of registrations, assets and pending credits in each state

How Long It Takes

The time needed depends on the scope of the question and how quickly documents are available:

• A focused question with clear facts, such as the rate on a product or the place of supply for a service: usually three to five working days after we receive complete documents.
• Multi-issue advice, such as a new business model or a set of contracts: typically one to two weeks.
• A GST health check of returns and records: two to four weeks, depending on the period covered, the number of registrations and the volume of transactions.
• Advance ruling applications: drafting takes about one to two weeks. The authority's decision takes longer and depends on its schedule and hearings.

Urgent questions, such as a contract that must be signed by a deadline, can often be prioritised if we receive the facts early. Delays usually arise when facts are incomplete or change during the review.

Pricing

Our professional fee for GST Advisory is ₹ 4,999.

This covers:

• An initial discussion to understand your question and the facts
• Review of the documents you share for the issue
• Research of the relevant provisions, notifications, circulars and rulings
• A written advisory note with conclusions and reasons
• A follow-up discussion to clarify the advice

This fee applies to a defined advisory query. Larger engagements, such as a full GST health check, restructuring advice, advance ruling applications, and representation before the department, are quoted separately after we understand the scope. Where an advance ruling or other application needs a government fee, it is payable at actual.

Common Mistakes to Avoid

• Copying a competitor's rate. Another business using a particular rate does not make it correct for your product. Classification depends on the actual nature and use of the goods or services.
• Assuming credit is available on everything. The law blocks credit on several items, such as certain motor vehicles, food and beverages, club memberships and works contracts for immovable property, subject to exceptions.
• Ignoring place of supply rules. Charging the wrong type of tax, such as central and state tax instead of integrated tax, means paying again in the correct head and claiming a refund of the wrong payment.
• Treating all foreign payments as exports. An export of services must satisfy every condition in the law, including the place of supply being outside India and the parties not being merely establishments of the same person.
• Not documenting positions. Even a correct position is hard to defend years later without a note explaining the reasoning and the facts at the time.
• Overlooking cross-state branch transactions. Supplies between registrations of the same PAN in different states can be taxable and need valuation under special rules.
• Acting on outdated advice. Advice given before a rate change, a new circular or a court ruling may no longer hold. Positions should be reviewed periodically.
• Waiting for a notice. Correcting a position voluntarily, with tax and interest, is usually far less costly than facing a demand with penalty.

What Happens After

Once you receive our advice, the next steps depend on the issue:

• Implementing the advice in your billing system, invoice formats, contracts and credit tracking.
• Correcting past filings where the advice shows an error, through amendments in later returns or payment of tax and interest through the appropriate form.
• Keeping records of the advisory note, the facts and supporting documents, which can be shared with auditors or the department when needed.
• Monitoring changes in rates, notifications and court decisions that could affect the position.
• Applying for an advance ruling, where the issue is significant and you want a binding answer.
• Responding to queries or notices from the department with a reply based on the documented position.

Our team can continue to support you through monthly return filing, periodic GST reviews, notice replies and representation before GST authorities.

FAQs

What is the difference between GST advisory and GST return filing?

Return filing reports transactions that have already taken place. Advisory decides how GST should apply to a transaction, product or arrangement, so that what you file is correct and defensible.

Can you tell me the correct GST rate for my product?

Yes. We look at the nature, composition, use and packaging of the product, apply the classification rules and the rate notifications, and give you a reasoned view. Where the classification is genuinely unclear, we explain the options and risks.

Is your advice binding on the GST department?

No. Professional advice is not binding on the department. Only an advance ruling binds the applicant and the jurisdictional officer, and court decisions bind according to their level. Our advice helps you take and support a well-reasoned position.

When should I apply for an advance ruling?

An advance ruling is useful when an issue has a significant tax impact, the law is unclear, and you want certainty before committing to a long-term arrangement. We help you assess whether it is worth applying and draft the application.

Can advisory help me reduce my GST liability?

Advisory helps you pay the correct tax, claim all credit the law allows and use available routes such as exports without payment of tax. It does not involve aggressive or artificial arrangements that the law does not support.

Do you advise on exports of services?

Yes. We review whether your supply meets the conditions for an export of services, the correct place of supply, whether to export under a letter of undertaking or with payment of tax, and how to claim refunds.

What if your advice shows I have been applying the wrong treatment?

We explain the exposure and the options to correct it, such as amending future returns or paying the shortfall with interest. Correcting voluntarily usually reduces the risk of penalties.

Can you review contracts for GST clauses?

Yes. We review clauses on tax inclusion or exclusion, rate change protection, credit matching, invoicing obligations and indemnities, and suggest wording that protects your position.

Do you advise on input tax credit mismatches?

Yes. We reconcile your purchase records with the auto-drafted credit statements, identify the reasons for gaps, and advise on follow-up with suppliers and the correct credit to claim.

Can I get advice on a one-time basis, or do I need a retainer?

Both are possible. Many clients seek advice on a single question. Businesses with frequent questions often prefer a periodic arrangement so that issues are addressed as they arise.

Do you advise on GST in restructuring and business transfers?

Yes. We advise on the GST impact of mergers, demergers, slump sales, transfer of a going concern and change in constitution, including transfer of unutilised credit and new registrations.

How do I share documents with you?

You can share documents electronically after the initial discussion. We only ask for what is needed to answer the question and handle all information confidentially.

Will you represent me if the department disputes the position?

Representation before GST authorities is a separate service. Our advisory note forms the base for any reply, and our team can prepare replies and appear on your behalf where you engage us for it.

How current is the advice you give?

Our advice reflects the law, notifications and rulings in force on the date it is given. Because GST rules change often, we recommend checking again before acting on advice after a significant gap.
