Those really just seem like ways of diversifying wealth and investments. Not an isk sink. All the isk bounties and NPC payouts input into the game will still be stacking up. Just changing hands a few more times. The only way to remove isk from the game is to either pay an NPC, frozen in cancelled accounts, or deleted punatively by the gamemasters.

More sales and broker taxes are a really bad idea. All it will do is make small single step outfits totally unprofitable. Instead, you will have to take something all the way from gathering inputs to final product since every step along the way adds cost. When taxes are low the cumulative additional cost isn't so terrible for a 5 step process, but if taxes were say 10% at each step it would be a 46% increase in cost from inputs to final product. It is impossible to compete when your costs are so out of line from big outfits who don't pay those costs.

Trying to entice ratters to become manufacturers to decrease the amount coming in from the bounty faucet? Probably not going to be very effective. They will just rat *and* have something on the side as well. Probably no effect on the net flow of the bounty faucets. Taxes will be more effective.

Another thought is tax on direct ISK transfers between characters. This could be in around the 7-8% margin and be applied to the sender when the ISK is transferred.

Doesn't surprise me that there are ways around it easily thought of, but I don't think that is really a concern. Tax evasion is possible in rl; why not in a game?

Another possibility would be to charge a monthly fee for alliance / corporation registration with the authorities. Maybe even a per-member tariff and per-corp tariff. The problem with that is "how do you enforce it?". Do you require the monthly fee to be paid in order to keep your station offices open? What happens if the fee is not paid? Disbanding the corp/alliance?
