SEP IRA and Trad IRA -- can you contrib to both?

Hi – I am self employed and annually max my contributions to my SEP IRA. It was suggested to me that I can do that and make the annual $6000 contribution to a trad IRA too. After some searching, I can’t find where that is allowed or not? Does anyone know the rule on that?

Thank you.

Yes, you can contribute to a SEP IRA and a Roth/Traditional IRA, but subject to income limitations.
