Frequently Asked Questions
Answers about estimate accuracy, tax coverage, privacy, and supported countries.
Can I use the results for tax filing?
No. Results are estimates for planning and comparison. They are not tax advice and cannot be used to prepare or file a tax return. For guidance based on your circumstances, consult a qualified tax professional.
How accurate are the estimates?
Estimates use the tax rules and calculation coverage available for the selected country, location, tax year, and period. Accuracy depends on the information you enter and the coverage shown by the calculator.
Why can my estimate differ from my actual net pay?
Actual net pay can differ because employers use payroll records, benefit deductions, contribution bases, plan selections, withholding elections, and payroll timing that are not fully reflected in an estimate. Review the calculation details and disclosures shown with your result and compare them with your payroll statement.
What taxes and contributions are included?
The U.S. calculator estimates federal income tax, state income tax, Social Security, Medicare, and supported local taxes. The China calculator estimates individual income tax and, where supported, employee social insurance and housing fund contributions. Each calculator shows what is included in the result.
Which countries and locations are supported?
GlobalSalaryTax currently provides calculators for the United States and China. The U.S. calculator covers all 50 states and Washington, D.C. The China calculator covers 60 cities. Automatic estimates for local contributions are available when the required rules for the selected city and period are verified.
Will you add more countries?
Yes. GlobalSalaryTax plans to support more countries over time. Countries marked Coming Soon are not yet available. Subscribe in the site footer to receive launch updates.
Which tax year or calculation period is used?
The U.S. calculator uses the selected tax year. The China calculator uses the selected tax year and calculation period, including the selected month where applicable. Check the selected period and coverage information before reviewing the result.
Does GlobalSalaryTax support income from self employment?
No. The calculators are designed for employment income. They do not estimate income from self employment, business taxes, corporate taxes, or related filing obligations.
Do you store my salary inputs?
Calculator inputs are processed locally in your browser and are not sent to GlobalSalaryTax as part of the calculation. The U.S. and China calculators can save up to five recent calculations on your device so you can review them later. Google Analytics is enabled only if you allow analytics in Privacy Preferences. Newsletter subscriptions and messages you send us are handled separately as described in our Privacy Policy.
