in most cases itemized deductions of which donations are a part offset ordinary income. because of the way the tax on long-term capital gains and qualifying dividends is computed ordinary income can push the tax on these from 0% to 20%. and then there can be the NIIT and or AMT taxes. so first you need to be able to itemize and then you need ordinary income other than qualifying dividends because those are treated just like net long-term capital gains. net short-term capital gains are just like ordinary income. too much in the way of itemized deductions could push you into the alternative minimum tax AMT. too much investment income can push you into the NIIT tax. just trying to point out that the answer to your question really depends on the numbers. your best option would be to buy the desktop software and then you can do all sorts of what-ifs admittedly these would be 2021 computations but it should be close to what 2022 would look like.
