We Analyse. We Calculate. We Correct.
A Chartered Accountancy practice for businesses that actually get audited — across India and sixty countries.
“Years signing returns, audit reports and reconciliations — for the businesses that actually get audited.”
Before we file, model, or sign, we understand the business. Numbers without context are noise; we begin with the conversation most firms skip.
Complex laws, simply applied. Whether it’s an Ind-AS adjustment or a TDS reconciliation, the working should make sense to a non-accountant.
When we find something off — in a return, an audit, a disclosure — we tell you, fix it, and tell you again. No surprises in the next inspection.
The full ledger of work a serious business actually needs in a year.
ITR Filing
Personal, HUF, partnership and corporate returns — prepared, reviewed and filed by qualified CAs. Every deduction caught, every disclosure in order, well before the statutory due date.
Tax Planning
Year-round strategy that lowers liability strictly within the law. We model scenarios — capital gains, ESOPs, dividend structures, family transitions — before they become problems on a return.
GST Returns
Monthly, quarterly and annual returns reconciled with your books and the GSTN portal. Reverse-charge, ITC matching, e-invoicing, departmental queries — handled in one quiet pipeline.
TDS / TCS Reconciliation
26AS, AIS, TRACES and your own books — matched line by line. Defaults closed, notices answered, certificates issued. The unglamorous work that keeps assessments uneventful.
Expat Tax & Transfer Pricing
DTAA relief, residency determination, equalisation levy, ALP studies and Form 3CEB — the cross-border work most firms decline. We do it for clients across the US, UK, Canada, Australia and the GCC.
Statutory Audit
Companies Act and Ind-AS compliant audits with audit trails clean enough to face any inspection. Led by partners, not by interns — with UDIN, CARO and internal-control reporting throughout.
A boutique CA firm built for the businesses that actually get audited.
Mercurius is a Chartered Accountancy practice headquartered in India, serving promoters, CFOs and global teams in more than sixty countries.
We exist for a specific kind of client — the founder who needs an audit signed without a sleepless quarter, the CFO carrying three jurisdictions on their balance sheet, the family office that wants its returns done once, properly, every year.
We are not a volume practice. Every engagement is led by a partner whose name is on the report. Every working is reviewable by a second pair of eyes. Every notice is answered in writing — never deferred, never forwarded to a junior.
The work is unglamorous and the deadlines are non-negotiable. That is why our clients stay with us for fifteen years and recommend us to people whose opinion they care about.
Twelve practitioners whose names are on every report we issue.
Ankit Jain

Siddhartha Havelia
Leads international tax, transfer pricing and cross-border audit. Built the firm’s outsourced accounting practice serving CPAs and CFOs across the US, UK, Canada and Australia.
