Excess money into taxable brokerage or HYSA to max out Roth IRA next year?

Excess money into taxable brokerage or HYSA to max out Roth IRA next year? Looking for some opinions. I have my Roth IRA maxed for 2026. I am currently setting aside a fixed amount of money from my monthly income to go directly towards my taxable brokerage account. I have some excess money that I am left with a month after budging my spending (excluding investments I’ve budgeted). I am trying to decide whether to put this excess directly into my taxable brokerage, or put this into a HYSA in order to max my Roth IRA on Jan 1st next year. Curious to what people think.
