They are efficient at not consuming too many resources while producing a lot of value? Probably shouldn't pay much then.
But this applies not only to big tech companies but to individuals too - they shouldn't pay much if they don't consume or extract from others.
Taxes are only a last-resort mechanism to raise money in absence of proper funding model.
If you can price government provided services appropriately then you don't need taxes.
Eg. to build infrastructure (roads, networks) you can predict that it'll benefit owners of nearby properties. They will benefit by landfall increase to the value of their property because the land on which it stands becomes more valuable.
So you collect the money for the infrastructure project by land "tax" before you begin with construction.
("tax" because it's not a tax but payment for exclusive land ownership rights)
