Your brokerage account is only taxable when you sell anything. Gains inside the account aren't realized until that point. If you do sell any securities you should receive a 1099-B showing the sales and that would need to be entered into your tax return.
You don't need to submit any forms with your tax return related to income inside a self-directed IRA. If you have generated Unrelated Taxable Business Income (UBTI) then your IRA custodian must file a 990-T and pay taxes on that income. You are also responsible for reporting to your custodian actual values in your SDIRA.
Here is a good discussion on the topic.
ok thank you! to clarify further, I do not pay taxes on any gains from contributions within my SDIRA, BUT do I pay taxes on gains from contributions in my self-directed brokerage account? Neither account has been withdrawn from, just contributed to.
