Do you pay taxes on money reported on 1099R form?

1099-R reports many different types of things...generally, distributions from pension and retirement plans, certain investments...and many others.

Depending on your plan and what is being reported, it may or may not, or normally, some portion of it is or isn't, taxable.

The form has a cell that shows taxable distributions compared to all distributions. That would be the amount already reported to the IRS as taxable to you.

It is also what you would need to show is at least your Required Minimum Distribution (RMD) for the plan noted, or risk making the whole amount in it immeadiately taxable.
