IRA Contribution Rules

Contribution amounts for Traditional and Roth IRA’s are the same; however, the age limits differ. IRA contribution rules may vary from year to year. You should periodically check both the contribution rules and the income rules to ensure your eligibility to participate and contribute. With TD Ameritrade, you have tools to help you see the value of regular contributions, such as our Cost of Waiting Calculator, which shows you the lost savings from waiting to contribute.

Catch-Up Contributions

While the age limits for making a contribution differ for the Traditional and Roth IRAs, both contain provisions for participants who are over age 50. You are allowed to make catch-up contributions once you reach age 50. Typically, the catch-up amount is $1,000 above the normal contribution amount.

Prior Year Contributions

If you did not maximize your contributions in the prior year, the IRS allows you to make a contribution in the current year and apply it to the prior year, provided you make the contribution by the tax deadline, normally April 15. 

Traditional IRA Contribution Rules

Traditional IRA contribution rules are based on your age, not on income. Deducting your contributions from your taxes is based on income.


The Traditional IRA contribution rules are categorized into three phases based on age:

  • Regular contributions are allowed up to age 50
  • Catch-up contributions are allowed between ages 50 - 70½
  • No contributions are allowed after age 70½

Roth IRA Contribution Rules

  • Regular contributions are allowed up to age 50
  • Catch-up contributions are allowed after age 50
