Does an 457 plan contribution affect an IRA contribution?

Yes, contributions to a 457 plan can affect your ability to contribute to an IRA, but they do not directly reduce your IRA contribution limit. However, if you exceed the income limits for traditional or Roth IRA contributions due to high earnings from your 457 plan, your ability to contribute to a Roth IRA may be phased out. Additionally, if you're covered by a retirement plan like a 457, it could affect the deductibility of traditional IRA contributions based on your modified adjusted gross income (MAGI).
