Total annual contribution limits for individual retirement accounts are set by the IRS. For traditional and Roth self-directed IRAs, the 2022 tax year limit is $6,000 for individuals under 50 years of age, and $7,000 for those over 50 years of age. The IRS increased traditional and Roth contribution limits to $6,500 (and $7,500 for those 50 and older) for 2023. SEP IRA contribution limits are considerably higher but depend on several key factors. More information can be found on the IRS website here.
