Free US tax calculators for federal, payroll, business, sales, and import planning.

The US Tax Calculators page is a dedicated hub for people who need quick, practical, and easy-to-understand tax estimates for the United States. It brings together calculators for federal income tax, state income tax, tax refunds, paycheck tax, payroll tax, self-employment tax, business tax, capital gains tax, sales tax, and customs duty. The page is designed for employees, freelancers, independent contractors, employers, small business owners, investors, shoppers, importers, bookkeepers, accountants, and anyone who wants a simple tax planning estimate before making a financial decision.

United States tax planning can involve many different tax systems at the same time. A worker may need to estimate federal income tax, state income tax, Social Security, Medicare, and paycheck deductions. A freelancer may need to estimate self-employment tax and quarterly payments. A business owner may need to check business profit, payroll taxes, credits, and estimated payments. An investor may want to estimate capital gains tax before selling an asset. An importer may need to estimate customs duty, MPF, HMF, tariffs, broker fees, and landed cost. This US tools page organizes those needs in one clear directory.

The US Federal Income Tax Calculator is useful for estimating taxable income, federal tax, credits, withholding, refund, or amount owed. Federal income tax depends on filing status, income, standard deduction, deductions, credits, and payments already made. Users often search for federal income tax calculator, income tax calculator USA, tax bracket calculator, taxable income calculator, or federal refund calculator because they want a direct estimate. The calculator gives a planning result, but final tax should always be verified with complete return information and official sources.

The US State Income Tax Calculator is useful because state tax rules vary widely. Some states have flat income tax rates, some have progressive rates, some have local tax rules, and some do not impose broad wage income tax. Because state tax varies by location and taxpayer situation, this calculator uses custom planning inputs so users can estimate state tax using a rate and deductions they choose. It is useful for people comparing jobs, moving between states, estimating withholding, or planning a state tax balance.

The US Tax Refund Calculator helps users estimate whether they may receive a refund or owe additional tax. A refund estimate is usually based on tax liability, withholding, estimated payments, credits, and state tax assumptions. Many people search for refund calculator, tax return estimator, tax refund estimator, or amount owed calculator because they want to know whether their payments during the year were enough. A refund is not extra income; it usually means payments or withholding exceeded the estimated tax amount.

The US Paycheck Tax Calculator is built for employees who want to estimate take-home pay after taxes and deductions. Gross pay can look very different from net pay because federal withholding, state withholding, Social Security, Medicare, pre-tax deductions, post-tax deductions, and pay frequency can all affect the final paycheck. This calculator is helpful for comparing job offers, checking payroll deductions, estimating biweekly or monthly net pay, and planning personal budgets around realistic take-home income.

The US Payroll Tax Calculator is useful for employers, payroll teams, bookkeepers, and small business owners. Payroll tax planning is different from paycheck planning because an employer may need to consider both employee withholding and employer payroll costs. Social Security, Medicare, FUTA, SUTA, employee deductions, and employer contributions can all affect payroll cost. This calculator helps users estimate payroll tax components in a simplified way so they can understand the difference between gross wages and total payroll cost.

The US Self Employment Tax Calculator is designed for freelancers, independent contractors, gig workers, consultants, creators, and small business owners who receive 1099 or non-W-2 income. Self-employed taxpayers generally need to plan for Social Security and Medicare tax through self-employment tax, and they may also need to set aside money for federal and state income tax. The calculator helps estimate self-employment tax, deductible portion, Additional Medicare tax planning, amount remaining after payments, and quarterly tax planning amount.

The US Business Tax Calculator is useful for business owners who want a simplified estimate of profit and tax after revenue and expenses. Business tax planning may involve gross receipts, returns, cost of goods sold, payroll expense, rent, marketing, vehicle costs, depreciation, interest, other expenses, QBI planning, credits, and estimated payments. The calculator supports common planning scenarios such as sole proprietorships, partnerships, S corporations, C corporations, LLC pass-through structures, and custom business assumptions. Actual business tax can be much more complex, but a calculator can help with early planning.

The US Capital Gains Tax Calculator is built for investors and sellers who want to estimate tax before selling stocks, crypto, real estate, or other assets. Capital gains tax can depend on sale price, cost basis, selling expenses, capital loss carryovers, holding period, filing status, other taxable income, and optional Net Investment Income Tax. Short-term gains are usually estimated differently from long-term gains because short-term gains generally follow ordinary income tax treatment, while long-term gains may qualify for preferential capital gains rates.

The US Sales Tax Calculator helps shoppers, e-commerce sellers, finance teams, and invoice creators estimate sales tax and final price. Sales tax can involve purchase amount, discount, shipping, exempt amount, state rate, local rate, custom combined rate, and tax-included pricing. Because state and local sales tax can vary by location and product category, this calculator is designed as a practical estimate rather than a compliance engine. Users can enter their own combined rate for more specific planning.

The US Customs Duty Calculator is useful for importers, e-commerce sellers, purchasing teams, and businesses that buy goods from overseas. Import cost is not only the product price. A shipment may involve merchandise value, freight, insurance, duty rate, additional tariffs, Merchandise Processing Fee, Harbor Maintenance Fee, brokerage fees, and other handling charges. The calculator estimates government charges and landed cost, helping users evaluate whether a product remains profitable after import costs.

Each US calculator page is designed to be useful beyond the initial calculation. The pages include calculator inputs, result cards, detailed breakdowns, related tools, educational text, FAQs, and disclaimers. This structure helps users understand what each result means and which assumptions may affect the estimate. For example, a paycheck calculator can lead to a federal income tax calculator, a payroll calculator can lead to a business tax calculator, and a capital gains calculator can lead to a tax refund calculator.

TaxCalculators.tools is an independent website and is not the IRS, SSA, CBP, a state tax agency, a tax filing company, a law firm, an accounting firm, or a financial adviser. Results shown by these calculators are estimates for education and planning only. Actual tax can differ because of official forms, filing status, deductions, credits, exemptions, state rules, local rules, payroll rules, import classification, customs valuation, business structure, investment details, penalties, interest, and updated government guidance. Users should verify final results with official sources, tax software, accounting records, or qualified professionals.
