Professionals in India, including doctors, lawyers, accountants, and consultants, must register for GST once their annual aggregate turnover exceeds ₹20 lakhs, or ₹10 lakhs in special category states. Crossing this threshold triggers mandatory compliance under the CGST Act, including filing GSTR-1 and GSTR-3B returns. Accurate turnover calculation, timely registration, and adherence to GST migration procedures are critical to avoid penalties and interest. TaxBuddy streamlines this process by monitoring turnover, pre-filling forms, and reconciling ITR and GST data. Its AI-assisted platform ensures professionals can transition smoothly, reducing compliance time and mitigating the risk of errors during GST migration.

Understanding GST Turnover Limits for Professionals
In India, service-based professionals such as doctors, lawyers, accountants, and consultants must register for GST when their annual aggregate turnover crosses ₹20 lakhs. In special category states like the Northeast, the threshold is ₹10 lakhs. This requirement applies specifically to services, differentiating it from goods suppliers whose threshold is ₹40 lakhs. Crossing these limits makes GST registration mandatory under the CGST Act, and professionals must comply with filing GSTR-1 and GSTR-3B returns. Failure to register promptly can trigger penalties of up to 100% of the tax due, along with interest at 18% per annum. Proper understanding of these limits ensures timely registration and avoids non-compliance risks.
Calculating Aggregate Turnover Accurately
Aggregate turnover includes all taxable supplies, exempt supplies, exports, and inter-state supplies, but excludes inward supplies under the reverse charge mechanism. For professionals, this often means consultation fees, retainers, reimbursements treated as supplies, and other service income. Turnover calculation uses the PAN across all business verticals, so all services under the same PAN are aggregated. Monitoring quarterly turnover via GST portal dashboards helps professionals anticipate threshold breaches. Accurate tracking ensures that registration and filing are completed on time, preventing penalties and interest. TaxBuddy automates this calculation, reconciling GST and ITR data for precise turnover monitoring.
Steps for GST Migration After Crossing Threshold
Upon crossing the GST threshold, professionals must register online via the GST portal using Form GST REG-01. Required documents include PAN, Aadhaar, bank details, and digital signatures. A provisional ID is issued within three days, followed by Aadhaar authentication or e-sign for approval in 3–7 working days. Professionals transitioning from the composition scheme must submit Form GST CMP-04. Once registration is approved, a 15-digit GSTIN is generated. Immediate updates to client invoices with the correct HSN codes are necessary to maintain compliance. TaxBuddy simplifies this process by pre-filling forms and tracking the registration status in real time.
Is Aadhaar Authentication Mandatory for GST Migration?
Yes, Aadhaar authentication is mandatory for professional GST migration. It provides identity verification and speeds up registration to three days in most cases. However, professionals can use alternatives like e-sign or electronic verification codes (EVC) if biometric authentication is not feasible. TaxBuddy supports all authentication methods, guiding professionals through the verification process and ensuring timely completion. This reduces delays and minimises the risk of late registration penalties.
How TaxBuddy Simplifies GST Migration for Professionals
TaxBuddy streamlines GST migration with AI-driven automation. The platform monitors turnover, flags threshold breaches, and pre-fills GST registration forms. It cross-references ITR and GSTR-3B data, identifying discrepancies that could trigger audits or penalties. Professionals with complex income structures can leverage TaxBuddy’s CA-assisted filing options. Auto-reviews every quarter reduce compliance time by up to 70%, allowing professionals to focus on their services rather than paperwork. Bulk invoice uploads and OCR scanning make post-migration filings efficient. TaxBuddy ensures that migration is seamless, accurate, and penalty-free.
Updating Invoices and HSN Codes Post-Registration
After GST registration, professionals must update all invoices to reflect the new GSTIN and accurate HSN codes. Incorrect HSN classification can trigger scrutiny from tax authorities. TaxBuddy automatically synchronises client and service data, generating invoices compliant with GST rules. This ensures that each transaction is accurately reported in GSTR-1 filings. Professionals can upload multiple invoices in bulk, saving time and minimising human errors. Maintaining updated invoices is crucial for smooth GST reconciliation and audit readiness.
Common Compliance Challenges During Migration
Migration challenges include inaccurate turnover calculation, missing documentation, delayed Aadhaar verification, and invoice mismatches. Professionals moving from a composition scheme face additional steps, requiring Form CMP-04 submission. Late registration or underreported turnover attracts penalties and interest. TaxBuddy mitigates these challenges by automating monitoring, providing alerts for missing documents, cross-checking ITR and GST schedules, and offering CA guidance for complex cases. Early detection of discrepancies ensures compliance and reduces audit risks.
Monitoring Turnover and Quarterly Reporting
Quarterly monitoring is essential for professionals to avoid unplanned GST registration or late filings. Aggregate turnover should be tracked continuously, including exempt and interstate supplies. TaxBuddy integrates turnover tracking with AI alerts, predicting when thresholds may be breached. It also prepares GSTR-1 and GSTR-3B drafts for each quarter, reducing manual work and ensuring timely submissions. This proactive approach helps professionals stay compliant without administrative stress.
Avoiding Penalties and Interest on Late Registration
Penalties for late GST registration can be up to 100% of the tax due, plus 18% annual interest. Non-compliance not only attracts fines but may trigger scrutiny during audits. Professionals should register immediately upon crossing thresholds. TaxBuddy helps avoid such penalties by alerting users when turnover is nearing the threshold, auto-preparing registration forms, and assisting with prompt filing. Ensuring correct bank details and Aadhaar verification further reduces the risk of errors.

It identifies discrepancies arising from exempt supplies, reimbursements, or misclassified transactions and provides actionable suggestions to reconcile the differences.

CA-assisted reviews further certify that mismatches are resolved according to regulatory standards.
Q6: Is Aadhaar mandatory for GST migration?

TaxBuddy supports all verification methods and guides professionals through each step, ensuring a seamless and compliant registration experience while reducing the risk of delays caused by missing or incorrect Aadhaar authentication.
Q7: How quickly is GST registration processed after submission?
After submission of Form GST REG-01, a provisional GST ID is usually issued within three days. Final approval is completed within 3–7 working days after Aadhaar or e-sign authentication. Timely submission of complete and accurate documents ensures faster processing. Platforms like TaxBuddy streamline this workflow by pre-checking documents, verifying details, and monitoring approval status, keeping professionals informed at each stage of the registration process and avoiding unnecessary delays.

Combined with AI-based verification, TaxBuddy ensures invoices are accurate, compliant, and ready for quarterly GST submissions.
Q9: What if a professional crosses ₹20 lakhs mid-quarter?
When a professional’s turnover exceeds ₹20 lakhs mid-quarter, GST registration must be completed within 30 days from the date of crossing the threshold.
