About TaxSaveIQ
Free, educational tax calculators built on current U.S. tax law — and kept honest by a qualified Chartered Accountant.
Our mission
Most people meet their tax situation once a year, under deadline pressure, through software designed to upsell. TaxSaveIQ exists to flip that: give anyone a clear, accurate estimate of what they owe and why — federal, state, capital gains, self-employment, and retirement contributions — for free, with no account required and no advice you didn't ask for. The goal is understanding, not a sale.
Methodology
Every calculator is built on the figures published in current law and adjusted for inflation by the IRS:
- IRS Rev. Proc. 2025-32 — the 2026 inflation adjustments for federal brackets, the standard deduction, and contribution limits.
- The One Big Beautiful Bill Act (OBBBA) — the 2026 SALT cap, the new tip and overtime deductions, the enhanced senior deduction, and related changes reflected on IRS Schedule 1-A.
- Official state Departments of Revenue— state income tax rates, brackets, exemptions, and treatment of retirement income, each cited on its state page with a “last verified” date.
Where a state has not yet published its 2026 figures, we use the latest enacted values and flag them clearly so you know an update is pending.
Editorial standards
- Tax data and calculator methodology are reviewed by Deepak Middha, a Chartered Accountant (ICAI) with 18 years in hedge fund accounting and tax.
- Each calculator shows its assumptions and a last-reviewed date, and links to its primary sources.
- We separate facts (rates, brackets, limits) from estimates (your projected tax), and we never present an estimate as a filing or as personalized advice.
- Corrections are made promptly when the law changes or an error is found.
