Traditional and Roth IRAs are two versions of the same idea, a tax-advantaged retirement account, that differ mainly on one axis: when you pay the tax. Getting the distinction clear is the foundation of most retirement-saving decisions.
A traditional IRA generally lets you contribute pre-tax dollars, potentially deducting the contribution now, and your money grows tax-deferred. You pay ordinary income tax when you withdraw in retirement. The appeal is a tax break today; the tradeoff is a taxable income stream later, plus required minimum distributions that force withdrawals at a certain age.
A Roth IRA works in reverse. You contribute after-tax dollars, no deduction today, but qualified withdrawals in retirement are tax-free, and there are no required minimum distributions during the original owner's life. The appeal is tax-free growth and withdrawals; the tradeoff is no tax break now. Roth contributions also have income limits, which is where the backdoor Roth comes in for higher earners.
The choice largely turns on whether you expect your tax rate to be higher now or in retirement, which no one can know for certain. Broadly, paying tax now, Roth, tends to favor those who expect higher future rates or have a long horizon for tax-free growth; deferring, traditional, favors those who expect lower rates later or want the deduction now. Many people use both. This is a decision to weigh with your tax advisor.
Now or later. The answer depends on a future you estimate.
