Planning Ahead: Important Tax Updates for 2026

Written by Alex M. Velazquez | Dec 11, 2025 2:00:02 PM

The IRS recently announced several updates that will shape tax and financial planning in both 2025 and 2026. These include higher retirement plan contribution limits, adjustments to tax brackets, and increases to the standard deduction. These changes give you more room to save and more opportunities to manage your tax bill. 

2026 Highlights at a Glance 

  • Higher standard deductions 
  • Additional deductions for adults age 65+
  • Increased retirement plan contribution limits 
  • Higher HSA and FSA limits 
  • Updated 2026 tax brackets

 

Key OBBBA Tax Rules  

The One Big Beautiful Bill Act (OBBBA) introduced new rules beginning in 2025. The standard deduction increases to $15,750 for single filers and $31,500 for married couples filing jointly. 

In 2026, the standard deduction will rise to $16,100 for single filers and $32,200 for married couples filing jointly. Taxpayers who are 65 or older can take an additional inflation-adjusted deduction of $2,050 if single or $1,650 per qualifying spouse if married. 

Note: A new temporary $6,000 bonus deduction is also available for taxpayers age 65 and older with income up to $75,000 (single) or $150,000 (married). This deduction runs from 2025 to 2028 and supplements the existing additional standard deduction.

*Please note, since the tax brackets above are for the 2026 tax year, they will generally apply to tax returns filed in 2027; 2025 tax rates will apply to returns filed in 2026. 

Making the most of the higher 2026 contribution limits 

One of the simplest ways to take advantage of the new limits is to increase your contribution percentage. If you have been contributing the same rate for years, even a small increase can meaningfully boost your long-term savings. Raising your 401(k) contribution by just 1 percent each year can add tens of thousands of dollars to your retirement balance over the long run without significantly changing your take-home pay. 

You should also make sure you are contributing enough to receive your full employer match. Many companies match between 3 and 6 percent of salary, and that extra money can make a substantial difference over time, especially as the combined employee and employer limit rises in 2026. 

Why these tax changes matter 

With higher contribution limits, updated tax brackets, and expanded deductions for seniors, 2026 offers several opportunities to strengthen your financial plan. It is worth revisiting your savings levels, making sure you take advantage of tax-advantaged accounts, and confirming that you are capturing every employer benefit available to you.
