You can contribute to multiple IRAs within one year, but the total amount contributed can’t exceed the annual limit set by the IRS. Use Publication 590-A to calculate this limit, which will be the smaller of either your earned income for the year or the annual contribution limit, and subtract any deposits you made to your Roth IRA account. Then, contribute to a traditional IRA, up to the limit, and report the deductible amount on Form 1040 or Form 1040-SR when you file your taxes. This deduction reduces your AGI, making your IRA contribution funds pre-taxed.
