Daniel earns 130,000 dollars as a single filer in California. Before planning, his numbers were roughly 20,447 dollars of federal income tax and 8,117 dollars of California income tax, on top of Social Security and Medicare.
His top federal dollars sat in the 24 percent bracket, and California added over 9 percent on the same slice. Every pre tax dollar he moved therefore saved him more than 33 cents.
He filled two accounts in order. First the 401k up to the employer match, because the match is free money before any tax argument. Then the health savings account, which is the only account that is deductible going in, untaxed while invested, and untaxed coming out for medical costs.
Between the two he moved 12,000 dollars out of taxable income. Federal tax fell by about 2,880 dollars and California tax by about 1,100 dollars, so the same paycheque left him roughly 4,000 dollars better off before any investment growth.
Two details mattered. Contribution limits are set per year and per account type, so he checked the current figures before setting the payroll deduction. And California does not follow the federal treatment of health savings accounts, so he kept a note for the state return rather than assuming the two matched.
The lesson: in a high tax state, a pre tax dollar is worth far more than the federal rate alone suggests.
