What's the best sequence? Timing?

[BTRR]

I'm ready to file the following 3 returns.  What's the best sequence and timing for filing?

Amended 2023 Return - The 8606 (for a distribution) was missing; it's now included.

Amended 2024 Return - The 8606 (for a distribution) was missing; it's now included.

2025 Return - It includes the 8606 (for a distribution).

Please advise.  Many thanks!

Steps to file amended returns for 2024 and 2024, and file an original 2025 with adjusted IRS Form 8606, "Nondeductible IRAs,"

• They should be filed in chronological order.
• Pay any taxes that you owe for 2025.
• Amended returns require manual processing,
• File the 2023 amende return and wait 2 weeks (or until it shows Processing)
• Then file the 2024 amended return and wait until both are completely processed.
• You can now E-file your 2025 tax return.
• Since you've paid the tax, there should not be a penalty.

Thanks! Very helpful!

For both my 2025 Federal and State returns, I'm getting refunds.  Since April 15th is less than 2 weeks away, how do I follow your sequence without missing the 2025 deadline?  Am I allowed to file my 2025 return after April 15?  Please help me understand.  Many thanks!

Yes, you can file after April 15th, but you will have to file an extension.   This will extend the time you have to file your taxes until October 15th, 2026.  

1. On the left rail menu in TurboTax Online Select Tax Tools  (You may have to scroll down on the left rail menu.)
2. On the drop-down select Tools 
3. On the Pop-up menu titled “Tools Center,” select File an extension
4. Follow the instructions to start the extension process 

Also, you may have to file your state taxes:

 Do I need to file an extension for my personal state taxes?

I don't think that there is any benefit to waiting to file your 2025 tax return.  I have never seen any evidence that the IRS tracks your IRA basis or compares Forms 8606 between years outside of an audit, instead relying on the taxpayer to provide accurate information on an individual Form 8606.  As long as your 2025 From 8606 is accurate relative to the amendments for 2023 and 2024, that should be sufficient.
