How much can I contribute to a SEP-IRA through my LLC while having a 401K through a W-2 employer

I currently work full time at a employer as a W-2 employee with a 401K. I also run a small business LLC that I opened a SEP IRA for as well.

 

I maxed out my W-2 Employer 401k contribution of $23,000 for the 2024, and employer match is $4,344.

 

I am looking to max out my SEP-IRA as well.  For 2024 I have $201, 354 in profits from my LLC.  

 

Shouldn't I be able to  deduct 25% of $201,354 = $50,388?

 

Instead it is telling me the maximum i can contribute is as follows: $62,731

                                          401K - $23,000

                                       SEP-IRA  - $39,731

 

Where / How is this $62,731 being calculated from? 

 

Employer match - $4344 - is not counted towards the total. 

 

THANK YOU!!!

Your maximum combined contribution for your SEP and your 401k is $69,000 for 2024.  The system seems to think you will have hit that limit if you contribute more than $39,731 to your SEP.  Do you have any other IRA contributions that are listed anywhere else in the return?

i checked my form 1040 and the $23,000 was already subtracted from outside employer W-2 salary.  

 

I think the $69,000 maximum is related to the self employed maximum? 

 

I have now removed any self employed 401K contribution and it now says that I have to contribute $62,731 to the SEP-IRA.  I am not sure how they got to this number bc 25% of $201,354 is $50,388?

Just to confirm.  One can contribute $23,000 through an outside employer sponsored 401k. 

IN ADDITION one can contribute up to $69,000 through a self employed IRA

 

thank you as I am a noobie

Nothing about additions to the 401(k) has any bearing on the maximum SEP contribution from your LLC.  SEP contributions are employer contributions ad employer contributions are unaffected by contributions at a different employer (as long as the two companies are not considered to be a controlled group that is required to be treated as a single employer for the purpose of a retirement plan).
