Roth Conversion vs. Roth Contribution

A conversion moves existing retirement money into Roth; a contribution adds new annual savings. The eligibility, limits, tax treatment, and records differ.

The short answer

Direct answer

A Roth contribution is new money contributed for a tax year and is subject to annual contribution, compensation, and income rules. A Roth conversion moves existing eligible retirement money into Roth and is not the same as an annual contribution.

Conversion income limits and annual contribution limits are different concepts. A person may be unable to make a direct Roth IRA contribution because of income yet still be permitted to convert eligible Traditional IRA money, subject to tax and other rules.

What are the main differences?

Contributions depend on compensation, filing status, modified adjusted gross income, and the annual IRA limit. They use current cash and do not produce a deduction for a Roth IRA contribution. A conversion starts with money already inside an eligible retirement account.

The previously untaxed conversion amount is generally included in income. A contribution is not income because it is funded with money already outside the Roth account. Each transaction also has distinct ordering and five-year-rule considerations.

  • Source of money: new savings versus an existing retirement account
  • Limits: annual contribution rules versus eligible amount available to convert
  • Income effect: no deduction for a Roth contribution; taxable conversion amounts add income
  • Records: contribution history versus conversion and basis reporting

Do Roth IRA income limits prevent a conversion?

The income limits for direct Roth IRA contributions do not operate as a general ban on conversions. IRS guidance states that a person may be able to convert Traditional IRA amounts regardless of adjusted gross income.

That does not make every related strategy simple. Existing IRA basis, aggregation rules, employer-plan rollovers, transaction sequencing, and current tax law can change the result.

Are the five-year rules the same?

No single “five-year rule” covers every Roth situation. Qualified-distribution rules, conversion amounts, earnings, age, and the timing of each conversion can matter. Treating contributions and conversions as interchangeable can lead to incorrect assumptions about access to money.

A person expecting to withdraw converted funds soon should verify the applicable ordering and additional-tax rules before converting.

Which records should be kept?

Keep annual contribution confirmations, Forms 5498 and 1099-R, Forms 8606, conversion statements, and records of the first Roth IRA contribution year. Custodian labels alone may not preserve every tax fact needed later.
