I think I'm mistaken on how I'm viewing this as I just did some more reading. I originally thought the income you get for writing calls is immediately taxable for that tax year. However, it appears that the income is not taxable until the call has been closed (ie., bought back, expired, etc). So, at the time the call has expired or bought back by the call writer, then it's a taxable event and the gains/losses are usually considered short-term capital gains/losses (but this appears more complicated for covered and qualified covered calls).
So, on the previous example of buying Jan15 100 calls and writing Jan15 110 calls, if you held both for more than a year and then closed position the person's Jan15 100 call profit would be long-term capital gains, while the loss for the Jan15 110 call would be short-term capital loss. This would actually be advantageous for tax purposes.
Anyway, there seems to be a lot of various scenarios and I'll defer to others who know more on this than me. But there's a good chapter on taxes (chapter 42) in Options as a Strategic Investment: Lawrence G. McMillan: 9780735204652: Amazon.com: Books

I think that would be the case if you bought and then sold the same call. But if you bought a Jan15 $100 call and then wrote a Jan15 $110 call, then I think you'd have both calls open.

I guess we're talking about a different example. The portion I quoted has exactly 2 activities: buy call, sell call. There are no future activities and thus no additional taxable events in question.
Let's say your tax rate is 50%. Buy a call at $10. Sell call "soon" after for $11. That's $1 profit per call. That's $100 profit for the whole transaction. I'd expect $50 net profit after the $50 taxes. I'm not seeing how that's "down" or why there are other tax implications.
