我厌倦了为我的有限责任公司（LLC）选择S-Corp时，在餐巾纸上进行粗略的计算，所以我在周末搭建了一个计算器。我发现的大多数工具要么忽略州/市税，要么向你收费才能得到答案，或者需要创建账户才能看到任何有用的东西。TakeHome完全在你的浏览器中运行（无需注册，没有分析，没有服务器端存储），并且在你拖动滑块时实时更新每个数字。它模拟的内容： - LLC自雇税与S-Corp W-2工资的FICA税- QBI扣除额（第199A条），附带SSTB逐步淘汰- Solo 401(k)，符合SECURE 2.0规则（传统/Roth/拆分，按年龄段划分的补足限额）- 自雇健康保险扣除额- S-Corp管理/合规成本比较- 纽约州所得税、特许经营税、PTET- 纽约市UBT（LLC），GCT（S-Corp），PIT，附带IT-219抵免额你可以保存方案，并排比较任意两个方案（它会准确显示哪些输入不同以及对美元的影响），并运行多维度的“假设”实验。还有一个AI模式，你用通俗易懂的英语描述一个场景，它会为你生成实验。税务引擎大约有2000行TypeScript代码，没有任何外部依赖。技术栈是React 19、MobX、Tailwind v4，部署在Cloudflare Workers上。AI功能使用Claude Haiku。注意事项：纽约/纽约市的税收已完全建模；对于其他司法管辖区，它在联邦层面是方向性的正确的（SE vs. FICA，QBI，401k分析与地点无关）。假设标准扣除额。假设QBI的SSTB。这不是财务建议，请将其视为与你的注册会计师（CPA）讨论的准备工作。我在每个计算出的项目上都添加了详细的工具提示，包括公式、IRS代码参考和源链接。每个数字都显示了计算过程。有兴趣听取反馈，特别是如果你发现了税务逻辑错误。也很好奇我是否应该优先考虑其他州（加利福尼亚州、德克萨斯州、佛罗里达州？）或下一步支持分项扣除。<a href="https://takehome.money" rel="nofollow">https://takehome.money</a>

I got tired of doing rough napkin math on whether to elect S-Corp for my LLC, so I built a calculator over the weekend.Most tools I found either ignore state/city taxes, charge you for the answer, or require creating an account to see anything useful. TakeHome runs entirely in your browser (no sign-up, no analytics, no server-side storage) and updates every number in real time as you drag sliders.What it models: - LLC self-employment tax vs. S-Corp FICA on W-2 salary- QBI deduction (Section 199A) with SSTB phase-out- Solo 401(k) with SECURE 2.0 rules (traditional/Roth/split, catch-up limits by age bracket)- Self-employed health insurance deduction- S-Corp admin/compliance cost comparison- NY State income tax, franchise tax, PTET- NYC UBT (LLC), GCT (S-Corp), PIT with IT-219 creditYou can save scenarios, compare any two side by side (it shows exactly which inputs differ and the dollar impact), and run multi-dimensional "what-if" experiments.There's also an AI mode where you describe a scenario in plain English and it generates the experiment for you.The tax engine is ~2,000 lines of TypeScript with no external dependencies. Stack is React 19, MobX, Tailwind v4, deployed on Cloudflare Workers. AI feature uses Claude Haiku.Caveats: NY/NYC taxes are fully modeled; for other jurisdictions it's directionally correct at the federal level (SE vs. FICA, QBI, 401k analysis are location-independent). Standard deduction assumed. SSTB assumed for QBI. Not financial advice, treat it as prep for a conversation with your CPA.I've added detailed tooltips on every computed line item with formulas, IRS code references, and source links. Every number shows its work.Interested in feedback, especially if you spot tax logic errors. Also curious whether I should prioritize other states (CA, TX, FL?) or itemized deduction support next.<a href="https://takehome.money" rel="nofollow">https://takehome.money</a>
