The 2026 tax brackets are set to change dramatically if Congress doesn’t act to extend current tax laws. When the Tax Cuts and Jobs Act (TCJA) expires at the end of 2025, taxpayers will face significant changes in their tax obligations. Understanding these projected 2026 tax brackets is crucial for financial planning, as more than 62 percent of tax filers are expected to experience tax increases in 2026. The upcoming changes to the 2026 tax brackets will affect everything from standard deductions to tax rates, making it essential to prepare for these potential modifications.
What Happens When the TCJA Expires
The Tax Cuts and Jobs Act transformed the tax landscape when it was passed in 2017, but many of its key provisions are set to sunset after 2025. When this happens, the tax system will largely revert to pre-2017 rules with some adjustments for inflation.
Key Changes Coming in 2026
1. Tax Brackets Will Shift
The current seven tax brackets (10%, 12%, 22%, 24%, 32%, 35%, and 37%) will change when the TCJA expires. The tax rates themselves will generally increase, and the income thresholds that determine which bracket you fall into will be adjusted.
2. Standard Deduction Gets Cut in Half
One of the biggest changes affects the standard deduction. The standard deduction will be cut in half when the TCJA provisions expire. This means:
- Single filers will see their standard deduction drop significantly from current levels
- Married couples filing jointly will also face a reduced standard deduction
- This will likely result in more filers choosing to itemize their deductions instead
3. Personal Exemptions Return
The personal exemption will be $2,000 per taxpayer and qualified dependents, adjusted for inflation when the TCJA sunsets. This provision was eliminated under the current tax law but will come back in 2026.
4. Itemized Deductions Expand
While the standard deduction shrinks, taxpayers will gain access to more itemized deductions:
- The $10,000 cap on state and local tax (SALT) deductions will be removed
- Limitations on the mortgage interest deduction, moving expenses, and the miscellaneous deduction are set to sunset
- More taxpayers may benefit from itemizing rather than taking the standard deduction
5. Child Tax Credit Changes
Child Tax Credit decreases 50% and phaseouts tighten when the TCJA expires. This means families with children will receive less tax relief than they do under current law.
6. Estate Tax Exemption Drops
Estate exemption drops from $13.99M to approximately $7M (inflation adjusted), which will affect wealthy families’ estate planning strategies.
Impact on Different Income Groups
The changes won’t affect everyone equally:
- Middle-income taxpayers are likely to see the biggest impact from reduced standard deductions
- High-income earners may benefit from the removal of SALT deduction caps
- Families with children will face reduced child tax credits
- Business owners will lose the qualified business income deduction entirely
What This Means for Your Tax Planning
The potential changes require proactive planning:
- Review whether you should accelerate income into 2025 or defer it to 2026
- Consider whether Roth IRA conversions make sense before rates potentially increase
- Evaluate your itemized deduction strategy as the calculation changes
- Reassess estate planning if you have substantial assets
The Role of Congress
It’s important to remember that these changes aren’t guaranteed. Congress can act to extend some or all of the TCJA provisions before they expire. Political discussions about tax policy will likely intensify as 2026 approaches, and the final outcome may differ from what current law dictates.
Preparing for Uncertainty
Given the uncertainty around which provisions might be extended, the best approach is to:
- Stay informed about legislative developments
- Work with a tax professional to model different scenarios
- Focus on tax strategies that provide benefits regardless of which rules apply
- Avoid making irreversible decisions based solely on projected changes
Bottom Line
The 2026 tax year could bring significant changes that affect most American taxpayers. While the exact details depend on congressional action, understanding the potential impacts of TCJA expiration helps you make informed financial decisions. The key is staying flexible and prepared for multiple scenarios while monitoring developments in tax policy as 2026 approaches.
