Tax Calculators for Independent Businesses

Independent income rarely arrives with taxes already withheld. If you wait until April to think about liability, cash that felt like profit in October can vanish into a payment you were not ready for. The goal of this category is not to replace a CPA—it is to give you clear planning numbers so you can reserve money on purpose.

Use these tools when you are freelancing or running a pass-through business, when quarterly estimates are coming due, or when you want a rough sense of self-employment tax and take-home pay. They are built around common US planning questions: what SE tax looks like on net earnings, how much to set aside, and what remains after a simple tax estimate.

Start with the Self-Employment Tax Calculator to see Social Security and Medicare-style SE tax on your net earnings from self-employment. Pair it with the Estimated Tax Calculator when you are thinking about federal estimated payments more broadly. The Quarterly Tax Reserve Calculator helps turn an annual tax picture into a per-quarter set-aside so cash stays available when vouchers are due.

When you care about lifestyle math—“what do I actually keep?”—use the After-Tax Income Calculator. It will not model every credit, state rule, or entity nuance. It will give a transparent estimate you can compare against your books and your advisor’s guidance.

Tax rules change, and your facts matter (entity type, state, filing status, deductions). Treat every result as educational planning, verify with IRS publications or a qualified professional before you file or send money, and update inputs when your income swings.
