Park a few wagons with some cheap goods in nearby native villages (say, with 50 horses or so on board). Save your game at the end of each turn. If the next turn gets you a favorable outcome (the goods you buy in Europe get cheaper, or the goods you sell get more expensive), save and keep on playing!
If you get a bad outcome (the king raises your tax rate, or the goods you buy in Europe get more expensive, or the goods you sell get cheaper), reload the saved game, and try buying or selling goods in a native village using the parked wagons. This usually changes the "trigger" for good or bad things happening, likely getting you at least a neutral outcome. You can also save up known "triggers" (combat, buying goods in Europe, etc.) for the end of the turn, and refrain from doing one or more of them that turn if the outcome for the next turn goes awry.
You should be trading extensively with the natives anyway, since they will offer some goods for sale (especially fur) at prices that are a fraction of what you can sell them for in Europe. I've gotten fur for about 1.5 to 2 gold apiece.
Using this technique, at turn 73 in a Pilgrim game, I've got a tax rate of only 1%. (The 1% raise happened on a turn where I got about 2000 gold in ancient treasure from a goody hut, so I wasn't going to forgo that just to keep the tax rate at 0%.)
