What is Turkish BSMV?
Banka ve Sigorta Muameleleri Vergisi (BSMV) is Turkey’s tax on financial transactions undertaken by banks, insurance companies, and certain financial intermediaries, governed by 6802 sayılı Gider Vergileri Kanunu (1956). BSMV applies to interest income, banking fees, insurance premiums, and brokerage commissions. It is a turnover-based tax (not KDV-style net VAT), so financial institutions cannot recover BSMV paid on their own purchases — creating a tax-cascade effect across financial value chains.
Standard BSMV rates
- 5% — most banking transactions: loan interest, deposit interest spreads, fees and commissions, FX trading spreads.
- 1% — interbank money market and certain repo transactions; some derivatives.
- 0% (exempt) — export financing, certain insurance lines.
- 10% — non-life insurance premiums (separate Insurance Tax mechanism with BSMV-like structure).
BSMV mechanics and KDV relationship
- BSMV is not KDV: banking and insurance services are KDV-exempt; BSMV is the substitute tax.
- No input recovery: unlike KDV, financial institutions cannot deduct BSMV they pay on their own inputs.
- Customer-side: BSMV is typically passed through to customers via loan rates, fees, or premiums.
- Declarations: monthly BSMV beyanname filed by financial institutions.
BSMV in fintech economics
The 5% transactions tax quietly reshapes Turkish fintech unit economics: it attaches to bank and insurer revenues — interest, fees, service charges — and licensed payment institutions’ fee income falls within its orbit, so pricing models imported from BSMV-free markets overstate margin by exactly that slice. Structuring questions follow: which entity in the value chain books the fee (a licensed institution’s revenue versus a technology provider’s SaaS fee changes the tax character), how interchange and scheme fees flow, and whether exemptions (notably some FX and capital-markets items) apply. In financial models and term sheets for Turkish fintechs, revenue lines should state whether figures are gross or net of BSMV — a one-word ambiguity that moves valuations.
