Calculating combined federal/state capital gains taxes on California home sale

Hello!

My wife and I have two dependent children, 11 and 14.

In 2024, we only had about $50,000 of income.

In May 2025, my wife and I sold our house in San Mateo County, California after 22 years as our primary residence. We have a capital gain of $980,000 (*after* the $500k deduction for married couple filing jointly, $686k for improvements/repairs, and $150k selling commissions/fees/taxes).

I'm confused as to how our combined federal & state capital gains tax for 2025 will be calculated or what our rate(s) will be.

In 2025, our regular income will consist entirely of approximately $100,000 in QUALIFIED dividends from Wells Fargo preferred stocks. I've read that 2025 qualified dividends will be taxed at 0% for up to $96,700 (married couple filing jointly).

When we file our 2025 taxes in April 2026, what will be our total taxable income? What will be our combined federal & state tax amount?

Thanks in advance for your expert help!
