Estimate business tax owed from revenue and expenses — flat rate or progressive brackets, using your own rates.
Our Business Tax Calculator estimates tax owed on your business profit — right in your browser, completely free, with no sign-up. It supports two modes: a simple flat rate (common for corporate/company tax) and fully customizable progressive brackets (common for sole proprietors and self-employed individuals taxed at personal income tax rates).
How your business is taxed usually depends on its legal structure:
Use whichever tab matches how your business is actually taxed.
A common misconception is that moving into a higher tax bracket means all your income gets taxed at the higher rate. It doesn't. Only the portion of profit that falls within each bracket is taxed at that bracket's rate — everything below it is still taxed at the lower rates. For example, with brackets of 10% up to 50,000 and 20% above that, someone with 60,000 in profit pays 10% on the first 50,000 and 20% only on the remaining 10,000 — not 20% on the full 60,000.
Tax rates and brackets vary by country, change with each budget cycle, and often depend on factors this simple calculator can't account for (deductions, credits, filing status, industry-specific rules). Rather than risk showing you an outdated or incorrect figure, this tool asks for your own rates — look up your current bracket structure from your country's tax authority, enter it once, and reuse the calculator for future estimates.

No, this is an estimate for planning purposes only. Always file through your official tax authority or with a qualified accountant, who can account for deductions and rules this calculator doesn't cover.
Check your country's official tax authority website (e.g. FBR in Pakistan, IRS in the US, HMRC in the UK). Enter the published thresholds and rates into the Progressive Brackets tab.
This varies by country and industry, but commonly includes costs directly related to running the business — supplies, rent, software, marketing, and similar. Check your local tax rules or use our Expense Tracker to keep a categorized log throughout the year.
