am doing this for a deceased person. I don't have the start amount of his annuity 30+ yr ago. Is this a problem or flag? I have the funds to pay what he owes.

It is in the ball park of what he pays every year. The annuity cannot be inherited by anyone if that makes a difference. He died in January so will only be 3 weeks worth of pension to report next year. Do I have to file that

For the current year's income tax return, you are computing the value of an annuity for the deceased.  If you do not have access to the previous year's income tax returns, there may be no one to contact or to ask a question.

Compute the best annuity valuation that you can with the information that is available to you.  Retain with the tax return papers, any explanation or computation should a tax authority have a question at a later time.

The income earned in 2025 will be reported on the 2025 Federal 1040 income tax return.  Use the same assumptions to compute the annuity values on the 2025 Federal 1040 income tax return.
