Frequently Asked Questions

Do I need to pay estimated quarterly taxes in Texas?
Texas does not have a state income tax, so no state estimated quarterly payments are required. However, if you are self-employed or have income not subject to withholding, you still must make federal estimated tax payments to the IRS if you expect to owe $1,000 or more in federal tax.
What federal estimated taxes do Texas residents owe?
Self-employed Texas residents owe federal self-employment tax (15.3% on the first $184,500 of net earnings for Social Security + 2.9% Medicare on all earnings) plus federal income tax. If you expect to owe $1,000+ after withholding, make quarterly payments by April 15, June 15, September 15, and January 15.
Why doesn't Texas require estimated tax payments?
Texas is one of the states that does not levy a personal income tax. Without a state income tax, there is no state tax liability to prepay through estimated quarterly installments. Self-employed residents only need to plan for federal estimated payments.
