Buying an Old Company in Kolkata? Due Diligence Checklist to Avoid Shell Company and Tax Traps

Kolkata has a very large number of old private limited companies, and some people buy them hoping to use their “vintage” for bank loans, tenders or credibility. But Kolkata was also at the centre of the shell company crackdown, in which the Registrar struck off lakhs of inactive companies across India and investigators traced accommodation entries and share capital routed through paper companies. A company you buy comes with all its past: unfiled returns, tax demands, bogus share capital, disqualified directors and criminal exposure. Thorough due diligence before signing is the only protection. Often, incorporating a fresh company is cheaper and safer.

Why buyers want an old company

• Tender conditions asking for years of existence or turnover.
• Bank limits or vendor registrations already in place.
• An existing trade name, licences, or property held by the company.
• Carried-forward losses (which may lapse; see below).

Red flags of a shell company

Red flag	What it suggests
No real business, staff or premises, but large share capital or share premium	Possible accommodation entries
Investments in other unlisted companies at high premiums, circular holdings	Layering of funds
Directors who are employees, drivers or relatives with no business role	Dummy directors
Registered office at a common address used by dozens of companies	Paper company network
Years of unfiled returns, struck-off or “active non-compliant” status	Regulatory exposure
Income tax reassessments, searches, or PMLA references	Serious liabilities

The due diligence checklist

MCA and corporate records

1. Company master data, filing history and status on the MCA portal.
2. Charges registered and satisfied (CHG forms).
3. Directors’ DIN status and disqualification; past companies of the directors.
4. Share capital history: every allotment, the money trail, valuation reports and FC-GPR for foreign investment.
5. Statutory registers, minutes, and the shareholding pattern.

Income tax

1. Returns and assessments for at least 6 years, outstanding demands, pending appeals.
2. AIS and Form 26AS; check for unexplained credits.
3. Reassessment notices and search history.

GST and other taxes

1. GST returns, notices, demands, ITC claims and suppliers.
2. TDS defaults on TRACES.
3. Profession tax, EPF and ESI dues.

Banking and assets

1. Bank statements for 3 years; large round-tripping entries.
2. Title of any property, encumbrances and KMC dues.
3. Licences, contracts and litigation.

Loss carry-forward lapses on change of control

For a closely held company, business losses of earlier years can be carried forward only if at least 51% of the voting power is held by the same persons at the end of the year of loss and the year of set-off. Buying more than 49% of an old loss-making company usually wipes out its carried-forward business losses (startups have a limited relaxation). Unabsorbed depreciation survives.

Tax on buying the shares

• Buyer: if you buy unlisted shares below their fair market value as per the valuation rules, the difference can be taxed as your income.
• Seller: capital gains on the sale, with fair market value deemed as the sale price if the agreed price is lower.
• Stamp duty on the share transfer, and demat requirements if the company is covered.

Protecting yourself in the agreement

• Detailed representations and warranties by sellers.
• Indemnity for pre-closing liabilities, with an escrow or deferred payment.
• Resignation of old directors and appointment of new ones on closing.
• A clean-up of filings before closing, not after.

Alternatives

• Incorporate a new company and build history; for tenders, form a consortium or use the promoters’ own experience where allowed.
• Buy the business assets rather than the company (slump sale or asset purchase), leaving old liabilities behind.
• See our private limited company registration in Kolkata.

Example: what a review found

A Delhi buyer was offered a 2009-incorporated Kolkata company “with clean records” for a tender. The review found ₹4 crore of share premium received in 2012 from three other Kolkata companies that were later struck off, a reassessment notice for that year questioning the share capital, two directors disqualified for non-filing in other companies, and GST registration cancelled in 2023. The buyer walked away and incorporated a new company, using the promoters’ own experience for the tender’s technical criteria.

Who should be on the review team

• A chartered accountant for books, income tax and GST.
• A company secretary for MCA records, registers and share capital history.
• A lawyer for litigation, property title and contracts.
• Where property is involved, a valuer and a title search at the registration office.

Quick checklist before signing

1. MCA status, filings and charges checked.
2. Directors’ DIN status and history checked.
3. Six years of income tax and GST records reviewed.
4. Share capital trail traced to bank statements.
5. Bank statements reviewed for round-tripping.
6. Litigation and notices searched.
7. Indemnities and escrow agreed in the share purchase agreement.

FAQs

Is it legal to buy an old company in Kolkata?

Yes, buying shares of a company is legal, but you inherit its past liabilities, so due diligence is essential.

Do carried-forward losses survive a change of ownership?

For closely held companies, business losses usually lapse if more than 49% of voting power changes hands.

How can I tell if a company is a shell?

Look for large share capital without business, dummy directors, common addresses, circular investments and unfiled returns.
