Quick Answer

What investors check in due diligence on an Indian startup: GST reconciliation, TDS defaults, FC-GPR, MSME dues under 43B(h), cap table and red flags.

A term sheet is not a deal. Between signing and money in the bank sits due diligence, where the investor's accountants and lawyers go through your company looking for reasons to renegotiate the valuation or walk away. Most founders treat this as a document-gathering exercise. The investors treat it as a risk hunt. The gap between those two views is where deals die.

This checklist is written from the investor's side of the table. It tells you what they actually look for, and which findings cause a discount, a delay, or a dead deal.

The Documents Every Diligence Team Will Demand

Before any analysis begins, the investor's team asks for a data room. If you cannot produce these quickly and cleanly, the process stalls and confidence drops before the numbers are even reviewed.

  • Audited financial statements for the last three years, plus the latest management accounts.
  • All GST returns (GSTR-1, GSTR-3B, GSTR-9) and a reconciliation against the books.
  • TDS returns, challans, and Form 26AS or the TRACES compliance record.
  • Income tax returns and assessment or notice history.
  • ROC filings: AOC-4, MGT-7, board resolutions, and statutory registers.
  • The cap table, share certificates, ESOP scheme documents, and all prior funding agreements.
  • Material contracts, IP assignment agreements, and a litigation summary.

The Red Flags That Move Valuation

Here is what the diligence team is genuinely scanning for, ranked by how badly each one hurts.

The Compliance Items Founders Most Often Miss

A few of these deserve a closer look because they are recent or commonly misunderstood.

MSME dues, Section 43B(h). From FY 2023-24, any amount owed to a registered micro or small enterprise that is not paid within the time limit agreed (capped at 45 days) is disallowed as an expense until actually paid. Diligence teams now test this directly because it both inflates taxable profit and reveals how a company treats its small suppliers.

Foreign investment, FC-GPR. If your startup has ever issued shares to a non-resident, you were required to report it to the RBI by filing Form FC-GPR within 30 days of allotment. Many early-stage founders raised a foreign angel round and never filed. This surfaces immediately in diligence and requires compounding with the RBI before a fresh foreign round can close.

Angel tax, Section 56(2)(viib). The angel tax, which taxed share premium above fair market value as income, was abolished for all classes of investors from April 2025. This removed a long-standing diligence headache for startups that raised at a premium. Valuation reports still matter for governance, but the specific angel-tax exposure is gone.

Cash and related-party hygiene. Section 269ST disallows cash receipts of Rs 2 lakh or more in aggregate from a person in a day. Diligence teams look for cash transactions near these limits and for any commingling of personal and business funds, which is one of the most common findings in founder-run companies.

How to Be Ready Before You Need to Be

You cannot manufacture clean compliance in the fortnight before a term sheet. The companies that sail through diligence do four things continuously:

The investor is not looking for perfection. They are looking for evidence that you run a disciplined company whose numbers mean what they say. Build that evidence over years and diligence becomes a formality instead of a threat to your raise.

Frequently Asked Questions

How long does financial due diligence usually take for an early-stage startup?

It depends mostly on how ready your data room is. If audited accounts, GST and TDS reconciliations, ROC filings and the cap table are available on day one, diligence can move in weeks. Missing filings, unreconciled returns or FEMA gaps typically add weeks or months while they are fixed or regularised.

What if we never filed Form FC-GPR for an earlier foreign investment?

Form FC-GPR is due within 30 days of allotting shares to a non-resident. A missed filing does not have to kill the deal, but it has to be regularised with the RBI, usually by filing with a late submission fee or through compounding, before a new foreign round closes. Start this early because it takes time.

Is angel tax still a diligence risk for startups raising at a premium?

The angel tax under Section 56(2)(viib) was abolished by the Finance (No. 2) Act, 2024, so share premium received above fair market value is no longer taxed as income for new issues. Investors may still check older rounds and valuation reports, and a registered valuer's report remains important under FEMA for foreign investment.

Why do investors check payments to MSME suppliers?

Under Section 43B(h), from FY 2023-24 an amount owed to a registered micro or small enterprise is deductible only when paid, unless it is paid within the agreed period, capped at 45 days. Late payments inflate taxable profit and signal weak payables discipline, so diligence teams test the creditor ageing directly.

Will small GST mismatches reduce our valuation?

Minor, well-explained differences between the books and GST returns rarely move valuation. What worries investors is unexplained mismatches, unpaid tax or ITC that may be reversed, because that becomes a contingent liability. Expect such amounts to be covered by an indemnity, escrow or price adjustment unless you reconcile and fix them before diligence.
