The 2026 cycle brings several stackable breaks: the new overtime and tips deductions, an enlarged standard deduction, and the usual retirement and HSA contributions that lower taxable income.
HSA contributions are triple-advantaged (deductible in, tax-free growth, tax-free for medical out), which often makes them the highest-value line for those with eligible plans.
Because deductions interact with brackets, the order and combination matter — modelling them together shows your real effective rate rather than each break in isolation.
