A Roth IRA can be a great idea — but not in all situations

Q: With all the debt our country is piling up, taxes have to rise. Doesn’t that make Roth contributions and conversions and avoiding pretax contributions no brainers?

A.: Ted,

Getting money into a Roth account is a great tax strategy for a lot of people but I can’t quite label it a no -brainer for everyone.

I think tax rate increases due to several factors are a very reasonable assumption but that alone should not dictate whether to fund a Roth account over a traditional retirement account with pretax funds. More important than increases in rates generally is the difference between the rate that applies to you at the time the Roth account is funded and the rate applicable to you when money is withdrawn.

Roth accounts are funded with after-tax money. You pay tax now, to avoid paying later. This is smart tax strategy if the rate you pay now is lower than the rate the rate that would be paid later. Figuring out the rate you pay now is straight forward but predicting future rates is more challenging because you will have multiple rates at play.

Congress can and likely will change the rates in the future. In fact, if new legislation isn’t passed rates revert to the pre-2018 schedules. However, even if no legislation were ever passed, the future tax rates that apply to you can still vary.

For instance, if you are married you face the rates that apply to married couples. At some point one of you will pass away. The survivor of the two of you then pays on the scale of a single filer. Ultimately when the last of the two of you passes, your beneficiaries pay at whatever rate applies to them. Meanwhile, if any of the parties receiving distributions moves to a new state, the difference in state income-tax rates would be a factor.
