So I am a single filer and my MAGI is above the limit for direct Roth IRA contribution so I perform a Backdoor Roth on a monthly DCA cycle throughout the year. In the 2025 year I did not max out my Roth IRA as I was focused on paying down debt. I get an end of year bonus but it is not paid out until March of the 2026 new year.
My plan was to use a portion of this bonus to max out my Roth IRA for the 2025 year. I wanted to continue to contribute to the prior year on a dca up until my bonus gets paid out. However, I do not get the option via Fidelity to contribute to the prior via Backdoor method as this is a conversion? I have the understanding that there is no limit on IRA conversions.
Can someone explain this to me? Am I not able to max out my 2025 Roth IRA via a backdoor after the year ends before April 15 new year? How do I go about contributing to the prior year?
