US Business Tax Calculator for Profit, Expenses, QBI, and Estimated Payments
In simple words
This free calculator estimates business profit and tax, from expenses and entity type to credits, payments, and amount due.
The US Business Tax Calculator estimates business profit and tax. It works for small business owners, LLC owners, sole proprietors, S corporation owners, and more. Business tax is not based on gross sales alone. The estimate includes expenses, entity type, tax rates, credits, and payments.
The calculator starts with gross receipts. It subtracts returns and allowances to find net revenue. Then it subtracts cost of goods sold. Cost of goods sold is what you paid for the goods you sell. The result is gross profit.
Next come operating expenses. These include payroll, rent, marketing, vehicle costs, depreciation, and interest. The result is business profit before QBI. QBI is the qualified business income deduction for pass-through businesses.
Entity type matters for tax. A sole proprietorship reports income on the owner's return. Partnerships and S corporations pass income to owners. A C corporation pays tax on its own. LLCs can be taxed in different ways. Pick the model that fits your business.
QBI planning is for pass-through businesses. The deduction can be valuable, but it has limits. QBI has income thresholds and other rules. This calculator uses a simplified QBI rate. It does not decide your final eligibility.
A C corporation uses a corporate tax rate. It does not get the QBI deduction. Corporate tax also involves dividends and other issues. This tool gives a simple corporate-level estimate. It is not a full corporate return.
Expenses can reduce profit, but not all are fully deductible. Some expenses are limited or spread over time. This calculator uses the amounts you enter. It does not judge whether each expense is legal. Keep your records and review them before filing.
You can set your own federal tax rate and state tax rate. State business tax varies a lot. Some states use income tax. Others use franchise tax or gross receipts tax. Enter the rate that fits your situation.
Credits and payments change the final result. Tax credits lower your tax. Estimated payments are taxes you already sent in. If payments cover the tax, you may see an overpayment. If not, you may see an amount due. Use this tool for planning, then check with a tax professional.
