Hi, wife and I decided to switch from Married Filing Jointly (“MFJ”) to Married Filing Separately (“MFS”) for Tax Year 2024. Our 2023 MFJ return showed a Loss Carry Over balance of $30k from our jointly owned investment account (registered in both names). How do we split/allocate this $30k evenly to our new MFS returns? My MFS return is a rollover/transfer from 2023’s MFJ file. Wife’s MFS return is a newly created return. Kindly advise how I can manually reduce $15k of Loss Carry Over on my return and input the same $15k to my wife’s return. TIA

After reading prior community posts, I searched Capital Loss Carryover on TurboTax Assistant. Clicked on prompt “Add/edit capital loss carryover info” and hype-linked to an Investment screen “Info from your 2023 tax return” with 8 amounts (Net short-term capital gain/loss, Net long-term capital gain/loss, Allowable loss, Income before exemptions, Net AMT short-term capital gain/loss, Net AMT long-term capital gain/loss, AMT allowable loss, AMT taxable income).

To do a manual transfer - is it just a simple edit (divide by 2) of the above 8 amounts on my 2024 return and then input the balancing differences to my wife’s 2024 return?

Also am I approaching this MFJ to MFS switch correctly on TurboTax?

Thanks again for your time and assistance. Much appreciated!

good evening Mike9241, thanks for your msg ... i am aware it's a 50/50 split between the 2 MFS returns ... i need to know how to go about to amend the $30k currently on my MFS return down to $15k - do I just edit all 8 figures with a 50/50 split? TIA

Yes. As stated by Mike9241, you split it evenly between you and there's nothing to amend for 2023. An amended return is not required in this situation.

Note: You can amend a return to change from Married Filing Separately to Married Filing Jointly but not from Married Filing Jointly to Married Filing Separately unless you do so prior to the original filing deadline without extensions. So, once you file a joint return you cannot change it to a separate return if the filing deadline has already passed.
