Roth IRA/Traditional IRA/SEP-IRA

[Mappocalypse]

Long time lurker, first time poster here.

I've been trying to read up on the rules regarding contributions to Traditional IRA/Roth/SEP-IRA and the IRS site is not that clear on my situation.
So without giving too much information, I have a regular job that issues W-2 and multiple side jobs with 1099s.
I already contribute 15% of my pay from my regular job to the company 401k (which matches 3%), and I contributed 25% of what I made from my combined 1099s into a SEP-IRA.

The question I have is that, even with the above contributions going on, would I still be allowed to contribute 5500 into a Roth IRA?

I get conflicting answers in numerous places, and seeing that many people here would probably have multiple jobs, they would be knowledgeable about this situation.

See 403B, Traditional IRA, HSA, and SEP IRA and
SEP Plan FAQs - Contributions.

In short, "yes".

Thank you!

I was confused since last year, my CPA had told me that I was disallowed from contributing to my Roth, but looking back, my income was above the allowable threshold.
