My income is increasing and I won’t qualify for a ROTH IRA. Is there a way around this? (Backdoor ROTH IRA)

Hi,

My income is increasing and I won’t qualify for a ROTH IRA. Is there a way around this?

I have heard that there is "Backdoor ROTH IRA" method to do that. But, I am not sure how to do it.

Currently, I have a Traditional IRA account to which I have transferred my previous 401K money.

Would you help me? Particularly, how to pay taxes during the process.
