计算器界面为英文。结果为教育和规划估算,不是报税结果、法律意见或专业税务建议; 多业务、QBI阶段限制、AMT/NIIT、抵免或多州情况请咨询CPA/EA。

这个计算器做了什么

1

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。

2

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。

3

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。
