Co Own - Who would be taxed on capital gains?

Sorry I am sort of new to this. Need advice!

I co own my primary residence with my brother 75/25 (On title). I’ve been living there for 2 years and he lives elsewhere at his primary residence. We want to sell the property (I’ll move back with my parents) and buy another a year from now.

If we were to sell, would he be taxed on capital gains? If so how can we avoid that?
