GST & Income Tax for Architects: Registration, TDS on Professional Fees, and ITR Filing

Unlike healthcare or (partially) legal services, architectural and design services carry no special GST exemption — a practising architect is taxed like most other professional service providers, which makes the compliance pattern more straightforward, if not lighter.

GST Registration for Architects

Architectural, engineering, and interior design services are taxable at 18% GST (SAC 9983 or the relevant sub-heading depending on the exact service — architectural services, urban planning, or engineering advisory). Registration becomes mandatory once aggregate turnover crosses ₹20 lakh in a financial year (₹10 lakh in special category states). There's no profession-specific exemption reducing this threshold or the rate.

Common triggers that push registration earlier than turnover alone would suggest:

• Inter-state project work — an architect based in one state taking on a project in another state typically needs registration regardless of total turnover, since the inter-state supply exemption is narrower than the intra-state one
• Working with real estate developers as a registered vendor — many developers require GST-compliant invoicing from all consultants for their own input tax credit chain, effectively requiring voluntary registration even below the threshold

Invoicing and Input Tax Credit

Once registered, an architect's practice can claim input tax credit on GST paid for business inputs — software licences (CAD, BIM tools), office rent, equipment, and subcontracted structural/MEP consultancy. This is one of the practical upsides of registration that partly offsets the compliance overhead: a design practice with meaningful software and subcontracting costs recovers a real amount through ITC rather than treating GST paid on inputs as a straight cost.

TDS on Architectural Fees

Clients paying professional fees above ₹30,000 in a financial year to an architect must deduct TDS at 10% under Section 194J (professional/technical services). For larger commercial projects, this can be a meaningful amount withheld against each milestone payment — architects should track TDS certificates (Form 16A) from each client through the year and reconcile them against Form 26AS before filing their return, since mismatches are a common source of processing delay.

Income Tax Filing for Architects

Situation	Form & approach
Gross receipts up to ₹75 lakh, opting for presumptive taxation	ITR-4, Section 44ADA — 50% of receipts presumed as taxable income
Receipts above ₹75 lakh, or maintaining full books	ITR-3, with tax audit required above the applicable threshold if not on presumptive basis
Practising as a partnership/LLP firm rather than individually	ITR-5 for the firm; partners file individually on their share of profit

Architecture is a notified profession under Section 44AA and 44ADA, so the presumptive scheme is available on the same terms as other professionals — worth evaluating year to year against actual expense ratios, since a practice running significant staff and software costs may genuinely have real profit margins below the 50% presumptive figure.

Practical Compliance Checklist

• Register for GST once turnover approaches ₹20 lakh, or immediately if taking on inter-state or developer-mandated work
• Issue GST-compliant invoices with SAC code, and claim input tax credit on software, rent, and subcontracted consultancy
• Track Form 16A from each client paying above ₹30,000/year, and reconcile against Form 26AS before filing
• Decide presumptive (ITR-4) vs full-books (ITR-3) filing based on your actual expense ratio each year

If you're setting up a design practice for the first time and unsure whether to register immediately or wait for the threshold, our GST registration service starts with an assessment of your specific client mix and project locations, and our ITR filing service handles both presumptive and full-books returns for design professionals.
