Yes, you can. However, regardless of the number of Roth IRA accounts you maintain, the total amount of contributions must not exceed the maximum contributions for any given year. Here are the 2020 limits for Roth IRA contributions - if you are under the age of 50, you can contribute a maximum of $6,000 per year, while those aged 50 or older can contribute $7,000 annually using catch-up contributions.
