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
Traditional / Roth IRA$7,000+$1,000

HSA (Individual)$4,300+$1,000 (55+)
HSA (Family)$8,550+$1,000 (55+)

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: Businesses with revenue over $2.47M
    • 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

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.
