Tax & Regulatory Compliance
Compliance is easier to manage when records, reconciliations and deadlines run as one process instead of separate last-minute tasks. We handle the monthly and annual cycle, and the reconciliations that keep it clean.

Who this is for
Businesses handling GST, TDS and income tax across multiple deadlines; companies where books and returns do not agree; businesses that receive notices and lack the reconciliations to answer them; smaller businesses that want one point of responsibility for the whole compliance cycle. We work with businesses across Tamil Nadu, and handle suitable engagements remotely.

Review
Findings and outputs are reviewed by the proprietor before anything is issued.
Report
Conclusions in plain language, with the decisions or filings they support.
Scope, deliverables and timelines are confirmed in a written engagement letter before work begins.
Common questions
Can a Cost Accountant handle our GST and income tax work?
Yes, for registration, returns, reconciliations, replies to notices and representation. Cost Accountants are recognised as authorised representatives under the GST law, and may appear before income-tax authorities as an authorised representative. Reports the law reserves for a Chartered Accountant, such as the tax audit report, are not undertaken; we prepare the workings and coordinate with your CA where one is required.
Our GSTR-2B never matches our purchase register. What is the fix?
Usually a monthly process rather than a one-time correction. Invoices are matched at document level, and differences are sorted into causes: supplier not filed, filed in a later period, wrong GSTIN, wrong value, or a purchase recorded but not received. Each cause has a different action. Left to the annual return, the same differences take far longer to trace.
We received a GST notice. What do you need from us?
The notice itself, the returns for the periods concerned, the books for those periods, and the supporting invoices. The first step is establishing what the department's figure is based on and reconciling it to your records. Most notices arise from a mismatch that can be explained with documents.
What changed in GST rates, and does it affect our invoicing?
From 22 September 2025, the 12% and 28% slabs were removed, leaving 5% and 18% as the main rates, with a 40% band for specified luxury and demerit goods. Rate masters, price lists and billing software needed updating from that date, and credit notes for earlier supplies carry the original rate.
Do you file returns for small businesses and individuals?
Yes. Proprietorships, partnership firms, LLPs, companies and individuals. Small businesses often need the reconciliation discipline more than large ones, because there is no one internally to catch a missed credit.
Can you take over compliance mid-year?
Yes. We review what has been filed for the year so far, reconcile it with the books, and list anything pending or incorrect. Corrections are handled through the available route, then the regular cycle continues from the current period.
Which MCA forms can you certify and file?
Several forms may be pre-certified by a Cost Accountant in whole-time practice, including INC-22, INC-28, PAS-3, SH-7, CHG-1, CHG-4, CHG-9, MGT-14, DIR-6, DIR-12, ADT-1 and GNL-3. Certification of AOC-4 is reserved for a Chartered Accountant in practice, and certification of the annual return for a Company Secretary in practice. We prepare and file the returns and coordinate on the certifications reserved for others.
What happens if we pay a small supplier late?
Where the supplier is a registered micro or small enterprise, payment must be made within the agreed period, capped at 45 days, or within 15 days where there is no written agreement. Late payment shifts the deduction to the year of actual payment and attracts interest under Section 16 of the MSMED Act at three times the RBI bank rate, compounded. From 1 April 2026 the provision sits in Section 37(2)(g) of the Income-tax Act, 2025. A year-end review of MSME payables usually pays for itself.
Filing requirements, forms and due dates change from time to time, and the position applicable to a business is assessed on its own facts. Certifications reserved by law for other professionals are coordinated with them rather than undertaken by the firm.
