Why the heck do you need tax rates to be so high at 69%?
You need to build up your economy, I recommend going for Star federation, you will be rolling in dough, even with amazingly low tax rates. |
The reason I go with such high tax rates is twofold:
1) Lower PQ and population colonies pretty much always have 100% approval. I crank up the tax rate to maximize the revenue:approval ratio of each planet. If 90% of my planets are at 100% approval, in effect, I am creating wasted morale with a lower tax rate. I milk every penny I can from colonies and keep them happy.
2) I do use the higher government types ASAP. Coupled with the increased economy bonus from the better government, I can amass a huge pool of reserve cash. Using this pool, when I decide to make my offensive actions, I can easily and quickly create cutting edge fleets in short amounts of time by simply buying the newly designed ships by the dozen.
When I am in the middle of my colony rush, I am usually looking at an incredible surplus of money. This allows me to either continue to expand, and buy lots of techs from other races, or simply start pooling up my money. The extra cash flow also aids in quickening my social project buildup by at least a few weeks.
It's also nice to be able to flat out buy trade goods and super projects, rather than spending the weeks and production points to build them, and instead use them to either solidify my economy, or start/continue military production.
This additional revenue also helps me maintain larger fleets. With 20 or so colonies at 15B pop a piece, generating on average 350BC per turn at 69% tax rate, my tax income alone is 7k BC. Add in trade and tourism and I'm sitting around 7.5-8k. If I nab economy resources... well, then my economy just really takes off.
As far as I can tell, tax rates are not linear; i.e. 20B people will not generate twice the amount of tax revenue that 10B generate. I'm am still investigating this, as there is no mouse-hover summary of tax income per planet.
To me, I find I have a much stronger and stable economy by keeping tax rates high, not wasting tiles on morale buildings. Instead, I take those tiles (which I would have used morale buildings) and use stock exchanges (which also serve as weak morale buildings themselves). 6 Stock exchanges are as good as 1 VR center as far as morale is concerned. But in addition, I get a 180% bonus to my base tax revunue, and 30% to my influence. On high PQ planets I can an income upwards of 600+ BC per turn for a single planet.
