I dunno if someone noticed it before or not. But, I did notice it.. Or if have been talked on previously.
Well, businesses have been paying tax on money that was already taxed after 5th of Jan, 2018.
/income is now subjected to the same tax rate that /deposit is.
Most of the transactions made are through bank accounts (or atleast some of them), which are already taxed while depositing.
For example : If an item costs $3000 in a store and a player buys it through his bank account. Let's say the current tax rate is 20%. So the money used to buy the item was already taxed 20% (i.e $750), but when the income is collected, it is again taxed 20%. So, as a result, an extra tax worth $600 on it is paid, which isn't a small amount. Considering that everyday 2 items like that are bought of which one through bank account, resulting into enormous extra tax of $4200/week.
As to reduce this, half of this tax should automagically be refunded back to the owner while doing /income. It would make game feel more realistic.
