    • There may be exemptions or reductions under double taxation treaties.

• • Detention ≥ 10%.

Despite all these costs, selling a well-prepared company tends to generate a higher return. A rigorous valuation, professional negotiation, and a proper tax structure can substantially increase the final value of the transaction. In many cases, investing in consultants and specialists is not just a cost, but a way to protect the seller and maximize the result.
