GST, TDS & Tax Compliance
Tax Compliance Operations That Stay Reconciled and Deadline-Ready
5th Quadrant organises the data, reconciliations and documentation behind your GST, TDS and income-tax compliance — so filings are prepared on a calendar, not assembled the night before a deadline.
Disciplined preparation and reconciliation, on a calendar you can see in advance.

Frequently Asked Questions
Can 5th Quadrant prepare and manage GST returns?
Yes — we prepare return data, reconcile GSTR-2B and input tax credit, and manage the filing workflow against an entity-wise compliance calendar.
Who is legally responsible for confirming a GST submission?
You, as the registered taxpayer (or your appointed GST practitioner where applicable), remain legally responsible for what is submitted. We prepare reconciled, review-ready data before every filing.
What is GST input-tax-credit reconciliation?
Matching the credit you've claimed against what's reflected in GSTR-2B, so eligible credit isn't missed and ineligible credit isn't claimed by mistake.
Can 5th Quadrant handle TDS calculations and returns?
Yes, including applicability mapping, calculations, payment and return preparation, and reconciliation against Form 26AS and AIS.
Does 5th Quadrant sign tax-audit reports or Form 15CB?
No. We prepare the underlying data and reconciliations; the tax-audit report or certificate itself is reviewed and signed by your independently engaged practising Chartered Accountant.
Can 5th Quadrant help organise a response to a tax notice?
Yes, we compile and organise the supporting data and documentation for a notice response, coordinating with your CA where the response requires professional certification or representation.
