Get your taxes done using TurboTax

The 2023/2024 tax results are the same either way.  However, the law requires that nondeductible contributions be reported, so reporting on the 2024 tax return only $500 of an actual $8,000 nondeductible contribution for 2024 would technically be a violation of section 408(o)(4)  of the tax code.  It's your choice.
