Frequently asked questions

Apply the marginal brackets to taxable income, then subtract credits. Deductions reduce taxable income; credits reduce the tax itself.
No. Brackets are marginal, so only the income inside each band is taxed at that band's rate. Your effective rate is always lower than your top rate.
Tax credits, because they cut the bill dollar for dollar. Retirement contributions and HSA payments come next by lowering taxable income.
