20%? Is this even real ? Most of the companies not related to gambling pay lower than 10% but not the same in Kenya when it comes to the sports gambling. Now the biggest football clubs have joined hands to oppose this rule.
I find it bizarre that you find 20% strange. It is the norm for most developed countries right now and seems like a fair amount to pay. That tax money should be going to fund everything that support the business - from maintaining the road network, to the medical/police/fire services, to the courts which prosecute violent thugs or thieves that may attack the casinos, to help the transport infrastructure that patrons use, paying for civil servants who should be keeping everything running with minimal corruption and many more things. It is very easy to forget that tax is meant to be a collective pool for the best interests of the public, especially if you come from countries where you struggle to trust those around you to be playing on the same level.
For people who are just aware about 10-15% tax percentage then they would really be finding that 20% or more would really be unusual but we know that each government is really different when it comes to that decision.
Important thing here is that tax should be used properly because this is the blood of the economy for countries progress.This doesn't only limit on gambling business but also other business as well.
If they do react on how much taxation deduction had been set out then they would most usually patch it up into their users but you cant still feel the difference.
