Form 8606 (Nondeductible IRAs) Instructions: Traditional IRA Deduction Limits vs. Roth IRA Contribution Phase-Outs
“Can I deduct my Traditional IRA contributions on my taxes if I also have a 401(k) at work?”
Official Procedural Summary & Rules
Traditional IRA contributions are deductible unless phased out by workplace plan coverage; Roth IRAs are non-deductible but grow 100% tax-free.
Key Statutory Rules & Exceptions
If you or your spouse has a 401(k) at work, Traditional IRA deduction phases out based on modified AGI. • High earners blocked from direct Roth contributions can use the "Backdoor Roth" strategy. • Failing to file Form 8606 for nondeductible contributions causes your own post-tax money to be taxed again upon withdrawal.
