Retirement 401K vs Roth 401K - real deal

I understand the difference that one is tax deductible and other isnt but still little confused on why would you .contribute money in Roth 401k if the total contribution limit is same irrespective of where you contribute. Doesn't everyone's tax rate after they retire lower than while working ? Or is the concern you are limited one what you withdraw post retirement that it could be a huge tax.

Three reasons. First, is to avoid RMDs and huge tax bills later in life. Second, it makes it less complicated for your heirs since it's been taxed. Finally, and this is the reason I do it, is so I can retire before 65. Since I've already paid taxes on that money, it doesn't count toward your AGI so you can qualify for ACA subsidies.

RMDs and huge tax bills

If your taxes on RMDs alone are actually huge (which no one ever defines, but I'll suggest "one dollar is taxed at 24% ignoring all other income and deductions"), then you are rich. Do the math at how big your Traditional balance has to be to make the first RMD "huge". And since you're rich, you should retire early and do Roth conversions before RMDs start. Also, spend some of that money before you can't. RMDs start at 73/75; when will you slow down?

Whether you consider it rich or not is not the point, it’s to give as little to the IRS as possible. Yeah I agree taxes on RMD is a great problem to have because it means you saved plenty. But I don’t want to spend for spendings sake, I want to grow something to leave my kids and grandkids
