Taxes & Levies Calculators
Calculate how much income tax, sales tax, or capital gains tax you'll owe — based on your income and location.
US Federal & State Income Tax Calculator
The United States tax system integrates progressive federal income tax schedules administered by the Internal Revenue Service (IRS), mandatory payroll contributions under the Federal Insurance Contributions Act (FICA), and state-level income taxes spanning progressive brackets, flat taxes, or zero-income-tax frameworks. This calculator projects your precise federal and state tax burden for the 2026 tax year, identifying your effective tax rate, marginal bracket tier, pre-tax savings impacts, and net annual take-home pay.
US Sales Tax Calculator
Sales tax in the United States is levied at state, county, municipal, and special transit district levels, creating combined sales tax rates ranging from 0% in states like Oregon and Delaware to over 10% in major metropolitan areas such as Chicago, Seattle, and Los Angeles. This calculator determines the precise breakdown of state and local sales taxes on any transaction, supports forward calculations (adding tax to price) and reverse calculations (extracting sales tax from a gross receipt), and accounts for statutory exemptions on groceries, prescription medicines, and apparel.
US Capital Gains Tax Calculator
Profits from the sale of capital assets — including stocks, bonds, mutual funds, cryptocurrency, real estate, and private business equity — are subject to federal and state capital gains taxes. The tax rate depends critically on holding period: assets held for one year or less trigger short-term capital gains taxed at ordinary income rates (up to 37%), whereas assets held for more than one year qualify for preferential long-term capital gains brackets (0%, 15%, or 20%). In addition, high earners are subject to the 3.8% Net Investment Income Tax (NIIT) and applicable state capital gains taxes. This calculator provides an exact calculation of your taxable capital gain, statutory federal tiers, surtaxes, and net in-pocket proceeds.
California Sales Tax Calculator
California imposes a 7.25% statewide base sales and use tax rate, comprising a 6.00% state rate plus mandatory 1.25% local county and city operational funds under the Bradley-Burns Uniform Local Sales and Use Tax Law. On top of this base, local voters in individual cities, counties, and transit authorities have approved district taxes that push combined rates as high as 10.25% in cities like Long Beach, Los Angeles, and South Gate. This calculator calculates exact California sales taxes and item exemptions.
Texas Sales Tax Calculator
Texas levies a 6.25% state sales and use tax rate under Texas Tax Code Title 2. Local taxing jurisdictions — including cities, counties, special purpose districts, and transit authorities — may impose additional local sales and use taxes up to a statutory cap of 2.00%, resulting in a maximum combined sales tax rate of 8.25% throughout the Lone Star State. This calculator computes exact Texas sales tax breakdowns, forward and reverse receipt calculations, and tax exemptions.
Washington Capital Gains Tax Calculator
Washington State enacted a 7% excise tax on long-term capital gains under RCW 82.87, which took effect for gains realized on or after January 1, 2022 and was upheld by the Washington Supreme Court in 2023. The tax applies strictly to long-term capital gains from the sale of financial assets like stocks, bonds, crypto, and business equity exceeding a statutory standard deduction ($262,000 for 2026). Real estate, retirement accounts, and small family businesses are statutorily exempt. This calculator computes your exact Washington excise tax alongside federal capital gains brackets.
US Self-Employment Tax Calculator
Self-employed individuals, independent contractors, freelancers, and sole proprietors pay federal self-employment tax under the Self-Employment Contributions Act (SECA, IRC §1401). Unlike W-2 employees where the employer pays half of FICA taxes, self-employed taxpayers are responsible for both the employer and employee portions — totaling 15.3% (12.4% Social Security and 2.9% Medicare). However, the tax code provides critical relief: only 92.35% of net profit is subject to SE tax, Social Security is capped at $184,500 for 2026, and exactly half of your SE tax is deductible above-the-line on Form 1040 Schedule 1. This calculator computes your exact Schedule SE tax, quarterly estimated payment obligations (1040-ES), and federal income tax savings.
US Tax Withholding Calculator
Federal income tax withholding from your paycheck is governed by IRS Publication 15-T and employee withholding certificates on IRS Form W-4. The redesigned W-4 eliminated confusing 'allowances' in favor of a five-step transparency framework that accounts for multiple jobs, working spouses, dependent credits, non-wage income, and itemized deductions. Getting your withholding right ensures you avoid unpleasant tax bills or IRS underpayment penalties (IRC §6654) without giving the government an interest-free loan through excessive refunds. This calculator simulates the percentage method used by employer payroll software to project your exact per-paycheck withholding, annual tax liability, and line-by-line W-4 adjustments.
US Tax Refund Calculator
Whether you anticipate a substantial federal tax refund or want to know if you'll owe the IRS in April, estimating your tax return before filing allows you to optimize deductions and plan your finances with confidence. A tax refund is not free bonus money — it is the return of your own overpaid income taxes that were withheld from your paychecks throughout the calendar year or remitted via quarterly estimated vouchers. This calculator models the full architecture of IRS Form 1040: starting from gross compensation, applying above-the-line adjustments to determine AGI, applying 2026 standard deductions ($16,100 Single / $32,200 MFJ), calculating progressive tax across statutory brackets (10% to 37%), applying refundable and non-refundable tax credits (such as the $2,000 Child Tax Credit), and reconciling your final tax liability against total pre-paid withholdings.
