Don't know why you didn't owe last year if you had self employment income. How old is your dependent?
You should send in quarterly estimated payments to cover the income tax and self employment tax (FICA) unless you have other tax withholding that will cover the SE Tax.

For SE self employment tax - if you have a net profit (after expenses) of $400 or more you will pay 15.3% SE Tax on 92.35% of your net profit in addition to your regular income tax on it. So if you have other income like W2 income your extra business income might put you into a higher tax bracket.
You must make quarterly estimated tax payments for the current tax year if both of the following apply:
- 1. You expect to owe at least $1,000 in tax for the current tax year, after subtracting your withholding and credits.
- 2. You expect your withholding and credits to be less than the smaller of:
90% of the tax to be shown on your current year’s tax return, or
100% of the tax shown on your prior year’s tax return. (Your prior year tax return must cover all 12 months.)
The 1040ES quarterly estimates are due April 15, June 16, Sept 15 and Jan 15, 2026. Your state will also have their own estimate forms.
