Note/Warning: These are all ESTIMATES based on what I understand the 2025 tax code covers built with the help of AI.  Both myself and the AI make many errors and are not perfect or any approximations of tax experts. For example, the AI often "forgets" Trumps BBB increased the SALT deduction to $40K for certain income levels, retroactive to the start of 2025. I tried to get this included but am not sure it calculates the roll-off of this "benefit" for higher incomes correctly. I find these calculations useful to ESTIMATE the effects of taking more capital gains or maybe paying a property tax bill before 2025 ends even if it is due in 2026.  At the bottom of the"2025 Tax & IRMAA Estimator for CA", I have a summary staring with "Detailed Tax Breakdown (Trace)" that you can highlight with your mouse and print out to compare different cases.
