Our verdict on Tax Foundation 2026 OBBBA Tax Calculator
Tax Foundation’s 2026 OBBBA Tax Calculator is a free web tool for people comparing illustrative federal individual income tax liability in tax year 2026. It puts liability under OBBBA provisions alongside a scenario in which the scheduled TCJA expiration had occurred. Users can explore sample taxpayer profiles or create a custom taxpayer scenario, making it relevant to filers who want to see how selected policy assumptions affect an estimate rather than calculate a complete return.
The comparison is the tool’s defining strength. It includes most aspects of federal individual income tax and accounts for certain OBBBA deductions, including qualifying tip and overtime income deductions, senior deductions, and qualifying auto loan interest deductions. That focus makes it useful for examining how those provisions may change an illustrative outcome. The scope remains federal, and it does not cover every tax scenario, so people needing state tax calculations or a comprehensive view of their circumstances should look for a broader calculator.
There is no charge to access the calculator, and it runs on the web. Its role is educational: Tax Foundation says it should not be used for tax preparation. Choose it to compare the two 2026 federal scenarios or explore the selected deductions in a sample or custom profile. Do not rely on it to prepare a filing or settle a tax bill; anyone who needs calculations beyond the covered assumptions should use a more comprehensive tax-preparation option.
