Investment banking fees — underwriting, M&A advisory and structuring — are generally not immediately deductible for business. They are usually treated as capital costs that reduce the proceeds of the transaction. Here is what to know.
Fees and Their Tax Treatment
Fees connected to raising capital (IPOs, secondary offers, debt issuance) are typically capitalised: they reduce the capital raised rather than offsetting operating income. This affects how and when tax benefit appears.
Common Rules
- Capital-raising fees: deducted against the proceeds, lowering the net capital received.
- M&A advisory fees: often capitalised into the cost basis of the acquisition.
- Ordinary services (recurring advice not tied to a transaction) may be deductible depending on structure.
Why They Are Not Deductible Upfront
Tax rules treat deal costs as related to the capital asset or transaction itself, so they surface over time (for example through amortisation or on sale) rather than as an immediate deduction.
Planning Considerations
Document every fee and its purpose, separate one-off transaction fees from recurring services, and check your jurisdiction's rules — they differ.
