Having one part of your corporation able to tax another part of it is actually incredibly useful for implementing separation of duties within a corporation.

For example, under the current system you can nominate your starbase maintenance team to use the master wallet for all starbase expenses. The starbase team then sets their desired slot fees based on running costs of the starbase.

A different wallet division is set up for use by the blueprint copying team. The blueprint copying team places their jobs into the starbase lab arrays, and the appropriate slot fees are automatically deducted from the blueprint copying wallet division and paid into the master wallet division.

When the starbase maintenance team needs to buy more fuel, they are able to use the slot fees that have accumulated in the master wallet to do so. It is then very easy to see whether the takings are sufficient to run the starbase or not, and to manage the funding of the starbase separately from the profitability of the blueprint copying.

Without the ability to set taxes at a starbase, maintaining this separation of duties would require a significant amount of manual accounting work to calculate the appropriate apportionment of starbase operating costs and manually transfer the appropriate amounts of ISK between wallet divisions.

If the tax is taken from one wallet and put into another it DOES make sense. Eg, industry guys putting money into the master wallet, through tax, to help pay their bit for the fuel.

To illustrate how it would be used (and how I have personally seen it used in the past)

You set up a wallet division called research.

You give the people doing research access to the wallet division research - this means they can put in money when they want to do research.

You set a cost for the research (current process - would be a tax rate under new method).

When someone wants to do research they put the bpo in a lab, they put the isk into the research wallet, they start research.

At present with this arrangement the cost goes into the master wallet, it can then be used to pay for say fuel. What people are suggesting is you should be able to set tax rates on your own pos which would mean the tax part of the cost of a job would go into the master wallet in the same way costs do now.

Thanks for the earlier reply to my other post.

Now a question;
We now have the facility to anchor a POS in high sector space but do I take it we will not be able to harvest moons?

I did try and set up a Moon Harvesting Array but got a long winded message about it had to be in 0.4 or less (I think). The message vanishes far too quickly to read it all and because it has multiple lines itGÇÖs very difficult to read all of it in one go.

No idea how viable it is, but:

Add a 20 minute online time (but not offline, preferably) to all arrays and labs. Then sure, you can play online/offline shenanigans, but it'd be annoying as hell to do regularly, with large times to do (as you can't online two things at the same time)
