كيف تعمل الضرائب الفصلية التقديرية
The US tax system is pay-as-you-go. Employees have taxes withheld from each paycheck automatically. If you're self-employed or have untaxed income, you must pay the IRS directly four times a year using Form 1040-ES.
If you underpay, the IRS charges an underpayment penalty (currently ~8% annualized). To avoid it, your total payments must be at least 90% of your current year tax or 100% of last year's tax, whichever is smaller (the "safe harbor" rule).

حول Quarterly Tax Calculator
If you are self-employed or have income not subject to withholding, the IRS requires you to pay estimated taxes four times a year — not once at tax time. Missing or underpaying quarterly estimates triggers a penalty even if you pay in full by April 15. Our quarterly tax calculator estimates each payment based on your net self-employment income, filing status, and applicable deductions so you can set aside exactly the right amount.
كيفية الاستخدام
- Enter your estimated annual net self-employment income (gross minus business expenses).
- Select your filing status and whether you have other W2 income.
- Enter any deductions you plan to claim (QBI deduction, retirement contributions).
- The calculator splits your total estimated tax liability into four quarterly payments.
الصيغة والمنهجية
SE tax = Net SE income × 0.9235 × 0.153. Federal income tax = Taxable income × Applicable bracket rates. Total estimated tax = SE tax + Federal income tax − Credits. Each quarterly payment ≈ Total / 4 (equal installments, safe harbor method).
