Planning for self-employment taxes in Texas
Texas has no individual state income tax, but self-employed people can still owe federal income tax plus Social Security and Medicare taxes. Estimated payments are normally divided across four payment periods during the year, but the amount due for any one period depends on when income arose, withholding and the safe-harbor rule that applies. This tool shows the reserve still to set aside, not your next required payment.
Use net profit, not gross revenue. If revenue is $100,000 and deductible business expenses are $20,000, enter $80,000.
This model covers ordinary sole-proprietor income. Ordinary self-employment tax generally starts when net earnings from self-employment reach $400; special rules may apply. If you also receive wages, enter your own wages so they count against the 2026 Social Security wage base. Additional Medicare Tax depends on filing status and covered wages as well as business earnings. It is separate from the deduction for one-half of ordinary self-employment tax.
