RMD Correction

[CHAS25]

I received an RMD calculation from the TSP that is incorrect and Is 10% larger than it should be, as the TSP refuses to use the Joint and Last Survivor Life Expectancy Table when appropriate as required by IRS rules.  I calculated my correct 2025 RMD and will file taxes using Tubo-Tax Deluxe. Is there a way for me to provide documentation of the correct RMD with my return so the IRS has the correct information?

You can’t attach a statement to your efliled return. You would have to print and mail your return. Or just explain your situation if audited.

@CHAS25 can you please be more specific and detailed on why you believe you are right and the TSP administrator is wrong?  what is your current circumstance? Married? widowed? etc. 

when is this joint and survivorship table appropriately used per IRS rules?  can you please explain? 

see this link. I see nothing stating that the Joint and Survivorship table is to be used to determined RMD.

@NCperson is correct. I found this on the web:

The TSP does not allow for the use of the Joint Life and Last Survivor Expectancy Table in RMD calculations. Participants are required to use the Uniform Lifetime Table, which may not be the most advantageous option for all individuals, particularly those with younger spouses
