How do OBBBA tax savings work?
The One Big Beautiful Bill Act reduces your tax burden through exclusions, increased deductions, and expanded credits. Each provision targets different taxpayer groups. Understanding the flow helps you maximize savings.
Step 1: Exclusions (Reduce AGI)
Tips and overtime are excluded from gross income before any deductions. This lowers your AGI and can push you into a lower tax bracket. Exclusions are more valuable than deductions because they reduce income at the top.
Step 2: Deductions (Standard vs Itemized)
You take the higher of standard deduction or itemized (SALT + charitable + auto loan interest). OBBBA increases SALT cap from $10K to $40K and adds auto loan interest โ so more people benefit from itemizing.
Step 3: Tax Calculation & Credits
Tax is calculated on taxable income using 2026 brackets. Child Tax Credit ($2,200/child) reduces tax dollar-for-dollar. Credits are more valuable than deductions โ a $2,200 credit saves $2,200 in tax.
Senior Bonus Deduction
If you are 65+ and income is under $75,000, you get an additional $6,000 deduction. This stacks with your standard or itemized deduction for extra savings.
๐ฏ Expert Tips
๐ก Track Tips Separately
Keep records of tip income โ the exclusion only applies to reported tips. Use our Tax-Free Tips Calculator for detailed analysis.
๐ก Itemize When SALT > Standard
If SALT + charitable + auto loan interest exceeds your standard deduction, itemizing saves more under OBBBA.
๐ก Overtime Documentation
Employers must report overtime separately for the exclusion. Verify your W-2 shows overtime in the correct box.
๐ก Combine Provisions
Tipped workers who also work overtime can stack both exclusions โ maximum tax relief for service industry workers.

Frequently asked questions about OBBBA
When did OBBBA take effect?
The One Big Beautiful Bill Act was signed July 4, 2025. Most provisions apply to tax year 2025 and beyond. This calculator uses 2026 inflation-adjusted brackets.
Who benefits most from the tips exclusion?
Servers, bartenders, delivery drivers, and other tipped workers. Single filers can exclude up to $25,000; married couples up to $50,000. The exclusion reduces taxable income, potentially lowering your bracket.
Is the overtime exclusion the same as tips?
No. Overtime pay is separate โ up to $12,500 (single) or $25,000 (married) can be excluded. You can claim both tips and overtime exclusions if you have both types of income.
How does the SALT cap increase help?
The old $10,000 cap limited deductions for state and local taxes. OBBBA raises it to $40,000. If you pay $35,000 in SALT, you can now deduct all of it (vs only $10,000 before), saving thousands in high-tax states.
What is the auto loan interest deduction?
OBBBA introduces a new deduction for interest paid on auto loans for personal vehicles. It works similarly to the mortgage interest deduction โ you deduct the interest, reducing taxable income.
Do I qualify for the senior deduction?
You must be 65 or older and have income under $75,000. The deduction is $6,000, reducing taxable income. It phases out above the income limit.
How is the Child Tax Credit different?
OBBBA increases the CTC from $2,000 to $2,200 per qualifying child under 17. Credits reduce tax dollar-for-dollar, so a family with 2 kids gets $400 more.
Should I use standard or itemized deduction?
Compare both. If SALT + charitable + auto loan interest exceeds your standard deduction ($16,100 single / $32,200 married), itemizing saves more. This calculator assumes the higher of the two.
