re: If I use points for a business trip, can I still deduct the cost from my taxes?

Ok cool.

2 questions
1) are you supposed to pay taxes on points (I presume the answer is yes)
2) do most people actually do this? (I suspect no)

The answer is a No. You do not owe any taxes on points or cashback earned from credit cards because these are treated as rebates. You owe no taxes on rebates. Straight from an IRS officer btw.

You can't write these off as expenses either. As far as points go (not cb), another reason that it can't be taxes is because it is impossible to assign monetary value to points. You may redeem your points for 0.8c per point while I may redeem the same points for 9c.

As far as paying for business trips with points, here is a relevant article on one of the blogs I enjoy: Hacking Business Travel

ETA: Like others, my suggestion would be to just pay for your business travel in cash and save the points for leisure that you can't write off anyway. Depending on your tax bracket, this could translate to upto 25-30% off on your business trips (Tax shield). And potentially lot more on your leisure trips (subsidized through points).
