Federal tax rules change every year, and even small adjustments to brackets, standard deductions, or the estate exemption can move a plan by thousands of dollars. This category pulls together the tax calculators most useful for personal planning, all updated to the 2026 IRS figures from Rev. Proc. 2025-32. Use the tax bracket calculator to see your marginal and effective rates at a given taxable income. The capital gains calculator handles short versus long term treatment and the 3.8 percent net investment income tax. Estate and QCD tools cover legacy and charitable planning, and the IRMAA calculator shows how Medicare Part B and Part D surcharges track modified adjusted gross income. These are planning aids, not tax preparation software; use them to understand the shape of your return, then confirm the final numbers with a qualified tax professional.
