2025 Tax Brackets (Filed in 2026)

Tax brackets adjusted upward for inflation—you may owe less even if income stayed the same.

Standard Deduction vs. Itemizing

Filing Status2025 Standard Deduction
Single$15,750
Married Filing Jointly$31,500
Head of Household$23,625

When to itemize: Your deductions must exceed the standard deduction.

  • Mortgage interest
  • State & local taxes (SALT) — capped at $40,000 (income limits apply)
  • Charitable contributions
  • Medical expenses (over 7.5% of AGI)

Tip: Many DFW homeowners take the standard deduction due to SALT limits and the higher deduction amounts.

Retirement Contribution Limits

Account Type2025 LimitCatch-Up (50+)
401(k) / 403(b) / 457$23,500+$7,500

Note: IRA deductibility phases out at higher incomes if you have a workplace plan.

Texas-Specific Considerations

  • No state income tax — but affects your federal strategy
  • No state estate tax — federal applies to estates over $13.99M
  • TX Franchise Tax: File every year; tax is due only if revenue is over $2.65M.
    • Retail/wholesale: 0.375%
    • Other businesses: 0.75%

Texas has no state income tax, but federal planning is still essential for high earners.

Year-End Tax Planning Strategies

The best planning happens before December 31st, not April 15th.

For Everyone:

  • Max out retirement contributions
  • Harvest investment losses
  • Bunch charitable donations
  • Review withholding (W-4)
  • Qualified charitable distributions (70½+)

For Business Owners:

  • Section 179 equipment purchases
  • Bonus depreciation
  • Employee bonus timing
  • Defer income / accelerate expenses
  • Review entity structure

We recommend a Q3 tax planning review while there's still time to act.

Pro Tips

Don't Wait Until April

The earlier you gather documents and consult with a CPA, the more planning options you have. Last-minute filing often means missed deductions.

Track Estimated Payments

If you make quarterly payments, keep records of each payment date and amount. These credits are sometimes overlooked or misapplied.

Review Withholding

Major life changes (marriage, new job, home purchase) warrant a W-4 review. Proper withholding prevents surprises at tax time.

Frequently Asked Questions

When is the deadline to file my 2025 tax return?
Your 2025 individual tax return (Form 1040) is due April 15, 2026. If you need more time, file Form 4868 by April 15 for an automatic 6-month extension until October 15, 2026. Important: an extension to file is NOT an extension to pay. You must estimate and pay any taxes owed by April 15 to avoid penalties and interest.
What are the penalties for filing late or paying late?
The failure-to-file penalty is 5% of unpaid taxes per month, up to 25% maximum. The failure-to-pay penalty is 0.5% per month, also capped at 25%. Interest accrues on unpaid taxes at the federal short-term rate plus 3%. The key takeaway: if you can't pay, file anyway. The filing penalty is 10 times higher than the payment penalty. We can also help you set up IRS payment plans.
Should I itemize deductions or take the standard deduction?
With the 2025 standard deduction at $15,750 (single) or $31,500 (married filing jointly), roughly 90% of taxpayers benefit from the standard deduction. You should itemize only if your mortgage interest, state/local taxes (SALT cap $40,000 with income limits), charitable contributions, and qualifying medical expenses (above 7.5% of AGI) together exceed these amounts. We run both calculations to ensure you take the larger deduction.
How do quarterly estimated tax payments work?
If you have income without withholding (self-employment, investments, rental income), you may need to make quarterly estimated payments using Form 1040-ES. The 2026 due dates are April 15, June 15, September 15, 2026, and January 15, 2027. To avoid penalties, pay at least 90% of your current year tax liability OR 100% of last year's tax (110% if your AGI exceeded $150,000). We help clients calculate safe harbor amounts.
What tax documents should I keep and for how long?
Keep W-2s, 1099s, receipts for deductible expenses, charitable contribution records, mortgage statements (Form 1098), property tax bills, investment statements, and prior tax returns. The general rule: keep records for 3 years from filing date. However, keep records for 6 years if you underreported income by more than 25%, and 7 years if you claimed a loss from worthless securities. We recommend keeping records for 7 years to be safe.
What's the difference between a tax credit and a tax deduction?
A tax deduction reduces your taxable income—if you're in the 22% bracket, a $1,000 deduction saves you $220 in taxes. A tax credit directly reduces your tax bill dollar-for-dollar—a $1,000 credit saves you $1,000. Credits are more valuable. Common credits include the Child Tax Credit, Earned Income Credit, education credits, and energy credits. We identify all credits you qualify for.
Can I still contribute to my IRA for 2025?
Yes, you have until April 15, 2026 to make IRA contributions for the 2025 tax year. This applies to both traditional and Roth IRAs. The contribution limit is $7,000 ($8,000 if you're 50+). For traditional IRAs, your contribution may be tax-deductible depending on your income and whether you have a workplace retirement plan. Roth contributions are never deductible but grow tax-free.
What if I made a mistake on a previous tax return?
File an amended return using Form 1040-X. To claim a refund, you generally have 3 years from the date you filed the original return or 2 years from the date you paid the tax, whichever is later. Common reasons to amend include missed deductions, incorrect filing status, or unreported income. If the IRS finds errors first, penalties may apply. If you discover a mistake, it's usually better to amend proactively.
