Self-Employment Tax Estimator
Uses actual 2026 federal tax brackets — not a flat rate estimate. Results update instantly.
Planning estimate only. Applies the standard deduction, a simplified QBI deduction below the threshold, the W-2 Social Security wage-base interaction, Additional Medicare Tax, and the deductible employer-equivalent SE tax. It does not cover QBI phase-ins, tax credits, AMT, NIIT, multiple businesses, community-property rules, or annualized-income installments. Consult a CPA or EA before filing or setting payment amounts.
2026 Quarterly Payment Calendar
Roughly reserve $3,701 by each deadline. Withholding, safe-harbor rules, and uneven income can change the actual payment.

这个计算器做了什么
SE Tax(自雇税)
净自雇收入×92.35%后,社会安全部分受2026年$184,500工资基数及W-2工资影响;Medicare无上限,高收入还可能有0.9% Additional Medicare Tax。
联邦所得税(区间估算)
按2026税率区间计算,并应用标准扣除和简化QBI估算。QBI阶段限制、SSTB、多业务和其他特殊规则未完整覆盖。
季度粗略预留
把估算剩余税额均分为四份,并用上年税额、上年AGI和预扣估算安全港参考。收入不均匀者仍需研究Form 2210年化分期法。
