Blocked Input Tax Credits (ITC) under Section 17(5) for Agencies

Understanding Blocked Credits under GST

While exporters can claim refunds on unutilized Input Tax Credit (ITC), Section 17(5) of the CGST Act blocks credit on specific goods and services, even if they are used for business operations.

Common Blocked Expenses

• Food, beverages, and catering services.
• Employee motor vehicle expenses (unless used for transport of goods).
• Personal consumption purchases.

Avoid claiming refunds on these blocked expenses to prevent GST audit penalties. Review the RFD-01 claims guide to clean up submissions.

Ensure your accounting team marks blocked items correctly to avoid input claim flags.

Statutory Compliance & GST Export Framework

Under Section 16 of the Integrated Goods and Services Tax (IGST) Act, 2017, export transactions are categorized as Zero-Rated Supplies. This legal position allows exporters to conduct business operations without tax liability. However, to maintain this tax-exempt status, businesses must adhere strictly to the rules laid down in Rule 96A of the CGST Rules, 2017. Under this rule, you must either export under a Letter of Undertaking (LUT) in Form GST RFD-11 or pay the applicable integrated tax (IGST) upfront and later claim a refund of the paid tax. Read more on filing and invoicing in our LUT Witness & Invoice Setup Guide.

Filing the Letter of Undertaking (LUT) is a mandatory step that must be completed prior to the commencement of export operations for each financial year. Exporters often make the mistake of issuing invoices with zero tax before filing the LUT. This omission is flagged during tax audits, resulting in demand notices from the department. The LUT is valid only for a single financial year (from April 1 to March 31), and a fresh application must be submitted online on the official GST Portal (gst.gov.in) at the start of every new fiscal period to prevent compliance disruptions.

Additionally, the place of supply for cross-border services must be determined in accordance with Section 13 of the IGST Act. In most cases involving remote consultancy, software development, and digital marketing, the Place of Supply is the location of the recipient outside India. However, if the services are classified as intermediary services (where the exporter merely facilitates a supply between two parties), the Place of Supply shifts to India, making the transaction subject to 18% IGST. Understanding this distinction is vital for digital agencies to avoid audit assessments, as discussed in our analysis of the GST Place of Supply rules.

Step-by-Step GST Portal Navigation for RFD-11

To file the Letter of Undertaking on the GST portal, follow this precise navigation pathway:

1. Log into the GST Portal using your registered tax credentials.
2. Navigate to the top menu and select Services > User Services > File LUT (RFD-11).
3. Select the correct Financial Year for which you are submitting the LUT from the drop-down menu.
4. If you have previously filed an LUT for the prior financial year, upload the previous LUT ARN receipt as supporting evidence.
5. Fill in the declaration check-boxes confirming that you will realize export proceeds within the mandated timeline.
6. Enter the details (Name, Address, PAN, and signatures) of two independent witnesses. Ensure their details match their official tax records. You can download the template from our LUT Witness affidavit guide.
7. Sign the application using your Digital Signature Certificate (DSC) or through Electronic Verification Code (EVC) OTP, then click submit.

Once submitted, the portal will generate an Application Reference Number (ARN) receipt. You must print this ARN number on all your commercial export invoices to satisfy customs and bank compliance officers during audits.

DTAA & Withholding Tax Exemption Framework

Double Taxation Avoidance Agreements (DTAA) are bilateral treaties signed between India and other countries (such as the US, UK, and Germany) to prevent taxpayers from being taxed twice on the same income. When Indian freelancers or agencies bill international clients, the foreign tax department typically requires the client to deduct Withholding Tax (WHT) of up to 30% from the payment. However, under DTAA rules, these rates can be reduced to 0% for independent services, provided you submit the necessary tax documentation. Refer to our DTAA No-PE Declaration Guide.

The most critical document required to claim DTAA benefits is the Tax Residency Certificate (TRC), which is issued by the Indian Income Tax Department. The TRC proves that you are a tax resident of India and are subject to Indian tax codes. Alongside the TRC, foreign clients will request a signed No Permanent Establishment (No-PE) Declaration. This declaration confirms that your business does not have a physical office, branch, or dependent agent in the client's country, exempting your professional profits from local taxes.

For US clients, Indian individuals must submit Form W-8BEN, while corporate entities must complete Form W-8BEN-E on the US IRS website (irs.gov). These forms contain treaty claims referencing specific articles (such as Article 15 for independent personal services). Filing these forms correctly ensures that you receive your export payments in full, avoiding complex tax recovery procedures.

TRC Application Procedure (Form 10FA and 10FB)

To obtain a Tax Residency Certificate (TRC) from the Indian Income Tax Department, follow this procedure:

1. Log into the official Income Tax e-filing portal (incometax.gov.in) using your PAN credentials.
2. Navigate to e-File > Income Tax Forms > File Income Tax Forms.
3. Select Form 10FA (Application for Tax Residency Certificate) for the relevant assessment year.
4. Fill in your business details, address, and the specific countries for which you require the DTAA treaty benefits.
5. Submit the application online. The Assessing Officer (AO) will review the application and issue the TRC in Form 10FB.
6. Download the issued TRC and provide it to your overseas clients along with the signed No-PE declaration sheet. Read our Form 10F online filing guide for portal details.

Reverse Charge Mechanism (RCM) & SaaS Import Rules

Under Section 9(3) and 9(4) of the CGST Act, 2017, the liability to pay GST shifts from the supplier to the recipient in specific transactions. This is known as the Reverse Charge Mechanism (RCM). When an Indian business imports services from an overseas provider (such as Slack, GitHub, Amazon Web Services, or OpenAI), the foreign vendor does not charge Indian GST. Instead, the importing business in India must self-assess the 18% IGST and pay it to the government. Read our Startup RCM Checklist.

A common mistake made by startups and digital agencies is failing to declare and pay RCM on foreign SaaS tool purchases. During audits, tax officers review bank statements and credit card logs to identify payments made to overseas entities. If they detect non-payment of RCM, they issue notices demanding the tax amount plus 18% interest under GST Section 50. Paying the RCM tax is mandatory even if the business is eligible to claim the paid amount back as Input Tax Credit (ITC), as explained in our Google & Meta Ads RCM Guide.

Under GST rules, the recipient of RCM services must issue a **Self-Invoice** under Section 31(3)(f) of the CGST Act. The self-invoice details the supplier's address, transaction value, and the applicable IGST rate. Once the tax is paid in the monthly GSTR-3B return, the business can claim the matching input credit in Table 4 of the same return, completing the compliance loop.

Step-by-Step RCM Reporting in GSTR-3B

To declare and reconcile RCM payments in your monthly GSTR-3B return, complete these steps:

1. Reconcile credit card statements and bank wires to identify payments made to foreign software or service providers.
2. Generate self-invoices for each RCM transaction and charge the 18% IGST.
3. Declare the total RCM taxable value and IGST liability in Table 3.1(d) (Inward supplies liable to reverse charge) of GSTR-3B on the GST Portal.
4. Pay the tax amount using the cash ledger (RCM liabilities cannot be settled using input tax credits).
5. Claim the paid IGST as Input Tax Credit in Table 4(A)(3) (Inward supplies liable to reverse charge) of the same return.
6. Ensure all entries match your purchase ledger to pass GSTR-9 annual audits.
