Since we're talking finances, funding an HSA should also be considered. Chances are one day you will be glad you did.
But I think HSA contributions are tax deductible? So yes they are a good idea but just like charitable donations and mortgage interest they will reduce your taxes, so you need to take them into consideration as you try and generate $7,500 of tax liability for the year.
Interesting. But I’ll be turning 70 1/2 next year, upon which partial withdrawals will be mandatory anyway. But likely not enough to generate $7,500 in tax liability. Not sure if it’s worth the hassle of converting to the ROTH at this late date. I guess I could always withdraw more than the minimum to get to that $7,500 tax liability without converting, but that IRA needs to last (hopefully) at least another 20 to 30 years.
You aren't really taking money from your retirement savings, it's just that your IRA has built up a tax liability over the years from any profits that were made and you are choosing to pay some of those taxes now. The method to do this is simple in concept, take money out of the IRA and you will owe some amount of tax. But withdrawing doesn't mean the same thing as spending, unless of course you use it to go on a cruise

but if you just move it into another savings or investment account, then from a retirement savings viewpoint it is just a transfer. Now when the funds are withdrawn they will possibly take withholding for taxes out at that time, which means you wouldn't be transferring the full amount into the new account. But next year when you file your taxes and take the $7,500 credit you should get most of that back as a refund depending on what else is going on with your taxes. You could then take the $7,500 refund or whatever amount it is and put it into the new account along with the other money.
The nice thing about IRA's and 401K's is that after you reach 55 1/2 you can pick and choose when you pay the taxes, by withdrawing specific amounts in a particular year and paying just that amount of tax. A year when you have a potential $7,500 deduction would in most cases be a very good year to pay some of your IRA or 401K tax.
What you do with the withdrawn IRA or 401K funds is the same decision as any investment decision, short term long term goals etc. If you weren't' really planning on changing anything, then whatever type of fund the IRA money was in, say a stock fund, you could move the money into the same or a similar fund, and keep going. But this also means that you will continue to generate tax liability on any profits generated in the new account from that point forward. This is why a Roth IRA is usually a better choice to move the money into, because the profits generated in a Roth IRA won't be taxable when you later withdraw it. Normally there are limits on how much you can invest in a Roth IRA each year, but the Roth conversion is sort of a loophole if you will that has no limit (that I know of) on how much you can transfer from a traditional IRA or 401K.
