Goods and Services Tax (GST) reshaped how service-based businesses in India handle invoicing, quoting and financial planning, and web design agencies sit right in the middle of it. Whether you are a startup commissioning your first site or an established brand managing a large web project, understanding how GST on web design services in India applies to every invoice you receive will save you from surprise costs, compliance gaps and lost Input Tax Credit. This guide walks through what you need to know, from classification and HSN codes to practical tips for budgeting your next project with confidence.

How Web Design Services Are Classified Under GST

The GST Council places web design, web development, website maintenance and related digital services under Service Accounting Code (SAC) 998314, which falls broadly within “information technology design and development services.” This classification matters because it triggers specific invoicing rules, place-of-supply determinations and, in most cases, the standard GST rate.

Most web design and web development projects delivered by Indian agencies attract 18% GST, the same slab that applies to most professional and technical services. Some components of a larger project may sit at different rates. For example, domain registration and web hosting services, when billed separately, can attract 5% GST under telecom or data services classifications. Printed design collateral such as business cards, brochures or signage carries 5% or 12% GST depending on the material. Keeping these distinctions clear on your invoice prevents mismatches that your tax auditor will flag later.

At Monk Creatives, we issue GST-compliant invoices for every project, from logo and brand identity work to full-scale website development, so that our clients can file their returns with complete transparency. We treat every line item with the correct SAC classification and make the applicable GST explicit, because a clean invoice is the foundation of a smooth filing season for everyone involved.

HSN or SAC Codes Every Business Owner Should Look For

When you receive an invoice from a web design agency, the document must display the relevant HSN or SAC code for each service rendered. For pure design and development work, you will see SAC 998314. If the agency bundles domain registration or hosting, those lines may carry different codes. Here is a quick reference table covering the most common codes you will encounter on web project invoices.

Ask your agency to share the codes upfront in the proposal stage. If they cannot, that is a signal to double-check the invoice when it arrives. A well-structured proposal should include a cost breakdown with SAC codes clearly listed so there are no surprises when the GST liability is calculated on top of your base quotation.

Place of Supply Rules for Cross-Border and Interstate Web Projects

GST is a destination-based tax, which means the rate and liability depend on where the service is “supplied.” For a business commissioning a website from an Indian agency, the default rule is that the place of supply is the location of the client, the business receiving the service. If the client is registered under GST, the agency bills GST and the client claims Input Tax Credit (ITC). If the client is not GST-registered, the agency still charges GST and remits it to the government, but the client cannot claim ITC on that portion.

When the client is located outside India, as with The Roots Company, a US-based brand that partnered with Monk Creatives for website development, the supply is treated as an export of services. Export of services is zero-rated under GST, provided the agency has a valid export declaration and the payment is received in convertible foreign exchange. This distinction is important: a cross-border web project does not attract Indian GST, but it requires proper documentation (foreign inward remittance certificate, export declaration) to claim that exemption.

How GST Affects Your Project Quotation and Budget

Most businesses focus on the base price when evaluating a web design or development proposal. GST sits on top of that, and for an 18% slab it is a material addition. A project quoted at ₹3,00,000 becomes ₹3,54,000 after GST. If you are managing a quarterly or annual creative budget, that difference needs to be built in from the start, not bolted on as a last-minute line item.

Here is where agencies and clients sometimes miscommunicate. An agency might say “the project costs ₹3 lakh” and the client hears “₹3 lakh all in.” If GST is not discussed explicitly in the proposal, the client’s finance team may challenge the invoice or hold up payment. The best practice is for agencies to present proposals in two figures: the base service fee and the estimated GST liability, making it clear which figure is the contract value and which is the tax component.

For retainer-based relationships, such as social media management or ongoing website maintenance, GST applies to every billing cycle. A monthly retainer of ₹25,000 plus 18% GST is ₹29,500 per month. Over a year that is ₹3,54,000, not ₹3,00,000. Budget planning for ongoing services requires the same discipline: always gross up the base fee by the applicable GST rate when forecasting cash outflows.

Winnies, a Chennai bakery, saw their Instagram following grow significantly through our social media management service. The monthly management fee carried 18% GST, which the client factored into their monthly marketing budget from the outset. This transparency helped keep the relationship smooth and the content pipeline uninterrupted. You can review that work on our Winnies portfolio page.

Invoicing Best Practices for Web Project Payments

A GST-compliant invoice for web design or development services must include several mandatory fields: the supplier’s and recipient’s legal names and GSTINs (if registered), a unique invoice number and date, SAC codes, the value of goods or services, the applicable GST rate and amount, and the total invoice value. For inter-state supplies, the invoice must also carry the words “Supply Meant for Inter-State Supply” where applicable.

Project-based web work often spans weeks or months, and many agencies use milestone billing. Each milestone invoice must stand on its own with complete GST details, you cannot issue one consolidated invoice at the end and retroactively allocate GST. If a project has four milestones, each milestone is a separate supply event and each invoice must show the SAC code, the applicable rate and the tax breakup (CGST and SGST for intra-state, IGST for inter-state).

Payment terms should also account for GST. A standard net-30 arrangement means the client has 30 days to pay the full invoice amount including GST. Late payment of GST by the supplier, even if the client has already paid, attracts interest under GST law. Choose agencies that have reliable processes for collecting and remitting GST on time; it protects you as much as it protects them.

Input Tax Credit, What You Can and Cannot Claim

One of GST’s core benefits is Input Tax Credit: the ability to set off the GST you pay on business inputs against the GST you collect on outputs. If your business is GST-registered, here is how it applies to web design agency costs.

You can claim ITC on GST paid for web development services used in the course of your business, a new website for your company, for example. You can also claim ITC on GST paid for ongoing website maintenance, digital marketing services, and design work such as logo design and packaging if those services are used for furtherance of business. However, ITC is not available on certain categories of expenditure, and the rules around blocked credits are worth knowing.

Web hosting and cloud infrastructure services generally qualify for full ITC if used for business purposes. Design and branding services qualify as well. If you use a portion of a website for personal or non-business purposes, you must apportion the ITC accordingly. Keep records of invoices, both those you receive and those you issue, because the GST department can request them during an audit, and the input credit claim is only as good as the documentation behind it.

Our website development service at Monk Creatives includes GST-compliant invoicing and the provision of all documentation you need to support your ITC claims. Whether it is a one-time build or an ongoing maintenance engagement, every invoice is structured to give your finance team what they need.

Budget Planning Tips for Your Next Web Project

Planning a web design or development project involves more than choosing a design direction and signing a contract. From a financial standpoint, here are the steps that keep your budget accurate and your compliance clean.

First, request a detailed cost breakdown from your agency before the project starts. Every line, design, development, content writing, stock photography, hosting setup, should carry an estimated cost and the applicable GST rate. This breakdown becomes your reference point for budget approval, internal cost allocation and, later, tax filing.

Second, clarify whether the quoted price is inclusive or exclusive of GST. Many Indian agencies quote exclusive of GST, which means you need to add 18% on top. Some quote inclusive. Both are legitimate, but the expectation must be aligned before you sign.

Third, factor in recurring costs. A website is not a one-time investment. Annual hosting, domain renewal, security certificates, content updates and performance optimisation all carry GST. Budget for these as operating expenses, not capital expenditure.

Fourth, if you are a GST-registered business, work with your chartered accountant early in the project. Confirm which project costs qualify for ITC and set up the accounting codes in your ERP or billing system before invoices start arriving. Retroactive reclassification at year-end is time-consuming and can lead to mismatches in your GSTR filings.

Finally, keep your agency informed of your GST registration status. If you register for GST mid-project, the agency will need to issue future invoices under the GST regime. If you deregister, they will need to adjust accordingly. A change in your GST status is a material detail that should trigger a conversation with your agency’s account manager, not sit unnoticed until the next invoice cycle.

Common GST Mistakes in Web Project Invoicing

Web design and development agencies in India make a handful of recurring GST errors, and clients who know what to look for can catch them before they become problems. The most frequent mistake is under-billing or omitting GST on services that clearly fall under the 18% slab. Another common error is applying the wrong SAC code, for example, using a generic professional services code instead of the specific SAC for IT design and development, which can lead to classification disputes during assessment.

Some agencies also fail to distinguish between intra-state and inter-state supplies when billing clients across state lines, leading to incorrect CGST/SGST splits instead of a single IGST charge. For agencies serving clients in multiple states, this requires careful tracking of each client’s state of registration. On the client side, the most common mistake is failing to claim eligible ITC simply because the supporting invoice is incomplete or because the expense was miscategorised in the accounting system.

Real project experience underlines why this matters. Pt Demolition, a building demolition firm based in Chennai, engaged Monk Creatives for a full website with a 400% profit increase within three months post-launch, a milestone that amplified the financial stakes around every invoice detail. Dharshan Adss, a signboard manufacturer, saw a similar outcome: after launch, their business recorded a 400% profit increase within three months. Both projects required precise invoicing, and both clients needed clean documentation to support their financial records as those results came in.

Working with a GST-Compliant Web Agency

The practical takeaway for business owners and marketing managers is this: your web design agency’s GST compliance is part of your compliance. A sloppy invoice from your agency becomes a problem in your books. Before engaging an agency, ask whether they are GST-registered, whether their invoices carry complete details including SAC codes and GSTINs, and whether they can provide a cost estimate that separates the base fee from the tax component.

Agencies that take GST seriously tend to take project management seriously as well. At Monk Creatives, every invoice for our website development service includes the full set of required fields, and our project proposals include a transparent cost breakdown so there are no ambiguities at billing time. This approach has served clients across industries, from healthcare trusts like Baros Trust to food brands like Kabab Corner, who rely on clean, compliant documentation for their own financial operations.

Budgeting for a web project with GST in mind is straightforward once you have the right information. Get a detailed proposal with SAC codes, confirm the GST rate, gross up the base fee by that rate, build in recurring costs for hosting and maintenance, and keep your chartered accountant in the loop. That process turns GST from a source of end-of-year surprises into a predictable line in your project budget.

Frequently asked questions

What GST rate applies to web design and website development services in India?

Web design and website development services generally attract 18% GST under SAC 998314. This applies to custom website development, UI/UX design, coding and front-end or back-end development work delivered by an Indian agency. Certain bundled components, such as domain registration or web hosting, may carry a different rate, typically 5% or 18%, depending on the service provider’s classification. Always check the specific line items on your invoice to confirm which rate applies to each component.

Can I claim Input Tax Credit on GST paid for a new business website?

Yes, if your business is registered under GST. The GST paid on website development services used for the furtherance of your taxable business is eligible for Input Tax Credit, provided the agency has issued a valid GST-compliant invoice showing your GSTIN, the SAC code and the tax breakup. Keep that invoice in your records. ITC is not available if your business is not GST-registered, or if the website is used partly for non-business purposes without proper apportionment.

Do I need to pay GST if my web design agency is based in a different state?

Yes. If the agency is in a different state, the supply is classified as inter-state and Integrated GST (IGST) applies rather than CGST plus SGST. The rate remains 18% in most cases, but the tax is collected and administered centrally through IGST rather than being split between the two states. The agency’s invoice must reflect IGST and carry both parties’ GSTINs.

How does GST apply to ongoing website maintenance and retainer contracts?

GST applies to every billing cycle of a maintenance or retainer contract. If you pay a monthly retainer of ₹25,000 for website maintenance, social media management or ongoing design support, the agency must charge 18% GST on each monthly invoice. Budget for this recurring tax component in your monthly or quarterly marketing and technology budgets, not just in the initial project cost.

What happens if my web agency does not mention GST on the invoice?

An invoice that does not include GST details, including the SAC code, applicable rate, CGST/SGST/IGST breakup and the supplier’s GSTIN, is not a valid tax invoice under GST law. You should request a revised, compliant invoice before processing payment. Using an invalid invoice in your own GST returns can lead to disallowance of Input Tax Credit, which effectively increases your tax liability. Ask for compliance upfront and keep a record of the corrected invoice.

Is GST applicable on website hosting and domain name registration?

Domain registration and web hosting services are typically classified under SAC 998429 and may carry 5% or 18% GST depending on the service provider’s classification and the nature of the service. If these are bundled into a web design package and not itemised separately, the entire package generally follows the 18% rate under SAC 998314. Ask your agency to itemise hosting and domain costs on the invoice so you can apply the correct rate and claim the appropriate ITC.
