Is a Roth 401k an option through your employer? With a Roth 401k you pay post-tax so you won't reduce you're taxable income but it will grow and be tax free when you pull it in retirement. It also allows you to contribute up to $17,500 per year, $12,000 more than a regular Roth IRA.

Edit 2: With my employer, I can elect my contributions to go into a Roth 401k instead of the regular 401k. They still do a company match, however their funds I believe have to go into the 401k plan and they need to do some extra math to determine the correct match amount due to how taxes affect the amounts.

Edit 3: Because most HNer's have high incomes, it might make more sense to contribute to a regular 401k and reduce your taxable income today. If you plan on saving lots of money and remaining in the same or going up in tax bracket in the future then Roth 401k might make more sense. The question is, do you think, generally, taxes and tax brackets will go up, down, or stay the same and how much money do you plan or hope to withdraw from your accounts in retirement?

Edit 4: I split my and my employer contributions about 50/50 between regular 401k and Roth 401k.
