will 417e table affect lump sum payment from DB plan

I'm 65.  I was offered a lump sum pension payment of $89,000.  I understand the amount will be recalculated when the new 417e table is released in June 2024.  Should I take the lump sum now or wait till after the new calculations are made in July 2024?

Likely 2 things are changing for your calculation.  One maybe the mortality table - generally speaking the update mortality table will result in a slightly lower lump sum.  Read your information carefully as they may also mention a change in the interest rates used to determine the lump sum.  Depending what rates they are using for the basis, the change in interest rates could be going either direction - up or down.  Generally, higher rates means lower lump sum.  If the interest rate is changing along with the mortality table in June, the change in interest rates could have a significant impact.

In addition,

• Timing is important:  Very likely, any change that applies would take effect at the beginning of the next plan year.  You should ask your HR rep (assuming that exists) what changes might apply and when.   
• And take into account that some plans require participants who are no longer employed to begin their payment (in whatever form they choose) at Normal Retirement Date (often, age 65) so that your proposed delay may not be permissible under the Plan provisions.

When the new 417e table is released, you will have your answer. But not until then. 

As Dirty, Harry would ask, 'Do you feel lucky?"

To clarify my OP, I assume in Bob's case the lump sum calculation he was given expires on June 30th and he was told that if he waits until after June 30th, the new value will be based on an updated mortality table, and I assume likely a new set of interest rates. The 2024 table was released last fall, and we know it will result in a slight decrease in the lump sum value.  

As fmsinc notes, we don't know when the 2025 table will be released, or if it will result in an increase or decrease.  Generally, the new tables are released in the fall.  I do not expect to see any new mortality tables released in June of 2024.
