## Tax glossary

Plain-English definitions for key income tax terms — covering concepts, country-specific terms, and international tax:

- [Capital Gains Tax](https://taxatlas.app/glossary/capital-gains-tax/): Tax on profit from selling assets like shares or property; rates and exemptions vary significantly by country — from 0% in Singapore to 33% in Ireland.
- [Double Taxation Agreement](https://taxatlas.app/glossary/double-taxation-agreement/): A treaty between two countries preventing the same income from being taxed twice; determines which country taxes which type of income and at what withholding rate.
- [Effective Tax Rate](https://taxatlas.app/glossary/effective-tax-rate/): Total income tax paid divided by gross income — the actual percentage of income going to tax; always lower than the marginal rate in a progressive system.
- [Expat Tax](https://taxatlas.app/glossary/expat-tax/): Tax obligations for individuals living or working outside their home country — covering residency, double taxation, foreign income exclusions, and exit taxes.
- [Fiscal Drag](https://taxatlas.app/glossary/fiscal-drag/): The automatic tax rise that occurs when inflation pushes wages into higher brackets without a real increase in purchasing power; also called bracket creep.
- [GST and VAT](https://taxatlas.app/glossary/gst-vat/): Consumption taxes charged at each stage of production; rates range from 5% (Canada federal GST) to 23% (Ireland VAT); the US has no federal equivalent.
- [ISA Allowance](https://taxatlas.app/glossary/isa-allowance/): The UK annual limit (£20,000 for 2026/27) for tax-free savings and investment; interest, dividends, and capital gains inside an ISA are permanently exempt from UK tax.
- [Marginal Tax Rate](https://taxatlas.app/glossary/marginal-tax-rate/): The rate of tax applied to your next dollar of income; the key number for evaluating extra work, deductions, and retirement contributions — not the rate on all income.
- [National Insurance](https://taxatlas.app/glossary/national-insurance/): UK payroll contribution (8% on £12,570–£50,270; 2% above) funding the State Pension and NHS; effectively a second income tax adding ~10 percentage points to marginal rates.
- [Personal Allowance](https://taxatlas.app/glossary/personal-allowance/): The income you can earn before paying UK income tax — £12,570 for 2026/27, tapering to zero above £100,000; equivalent concepts exist in Ireland, India, and other countries.
- [RSU Taxation](https://taxatlas.app/glossary/rsu-taxation/): Restricted Stock Units are taxed as ordinary employment income at vesting; only subsequent appreciation is a capital gain — the most common RSU tax misconception.
- [Section 80C](https://taxatlas.app/glossary/section-80c/): India's most-used deduction — up to ₹1,50,000/year on EPF, PPF, ELSS, life insurance, and more; available under the old tax regime only; saves up to ₹46,800 at the 30% rate.
- [Section 87A Tax Rebate](https://taxatlas.app/glossary/section-87a/): India's direct tax rebate making income up to ₹7,00,000 (new regime) effectively tax-free; combined with the ₹75,000 standard deduction, salaried employees earning up to ₹7,75,000 pay zero tax.
- [Self-Employment Tax](https://taxatlas.app/glossary/self-employment-tax/): US term for the 15.3% FICA equivalent paid by self-employed individuals — covering both employer and employee shares of Social Security and Medicare.
- [Standard Deduction](https://taxatlas.app/glossary/standard-deduction/): The fixed amount US taxpayers subtract from income before calculating federal tax — $14,600 for single filers in 2026; taken by approximately 89% of Americans.
- [Superannuation](https://taxatlas.app/glossary/superannuation/): Australia's compulsory retirement savings system; employers contribute 11.5% of ordinary earnings (2026-27) taxed at 15% inside the fund; tax-free withdrawals after age 60.
- [Take-Home Pay](https://taxatlas.app/glossary/take-home-pay/): Net income after income tax, social security contributions, and other withholdings — the amount deposited to your account; always lower than gross salary.
- [Tax Bracket](https://taxatlas.app/glossary/tax-bracket/): An income range taxed at a specific rate in a progressive system; only income within each bracket faces that rate — crossing into a higher bracket never reduces net pay.
- [Tax Credits vs Tax Deductions](https://taxatlas.app/glossary/tax-credits-vs-deductions/): Credits reduce tax liability dollar-for-dollar; deductions reduce taxable income at your marginal rate — a $1,000 credit is always worth more than a $1,000 deduction.
- [Tax-Free Threshold](https://taxatlas.app/glossary/tax-free-threshold/): Australia's $18,200 zero-tax band for 2026-27; claimed via TFN declaration; non-residents cannot claim it and pay 32.5% from the first dollar of Australian-source income.
- [Tax Residency](https://taxatlas.app/glossary/tax-residency/): The legal status determining which country taxes your worldwide income — distinct from citizenship; each country has its own tests, and dual residency triggers double-taxation treaty tie-breakers.
- [Tax Year](https://taxatlas.app/glossary/tax-year/): The 12-month period for calculating income tax; varies by country — US and Canada use January–December; India uses April–March (Financial Year); UK uses 6 April to 5 April.
- [TDS (Tax Deducted at Source)](https://taxatlas.app/glossary/tds/): India's withholding system where payers deduct tax before payment across salary, interest, professional fees, rent, and dozens of other categories; credits appear in Form 26AS.
- [Withholding Tax](https://taxatlas.app/glossary/withholding-tax/): Tax collected at the source of income by the payer before it reaches the recipient; covers employment income (PAYE, PAYG, TDS) and investment income paid to foreign investors.
