Solo 401k - how to I claim the $500 tax credit?

Hi,

I set up a solo 401k (self-employed, no employees) with auto-enrollment option, in February 2026 and I will make contributions for 2025.

Can I claim the $500  ($1500 spreed over 3 years) auto-enrollment option tax credit for 2025, or only for 2026 and forward (2027 and 2028)? Form 8881 Part II.

 

Thanks
