Payroll tax is a tax imposed on employers or employees, typically calculated as a percentage of the salaries that employers pay their staff. It is used primarily to fund social insurance programs like Social Security and Medicare in the United States, ensuring a safety net for retirees, the disabled, and other eligible beneficiaries.
The Physical Presence Test is used by the IRS to determine if a U.S. citizen or resident alien has spent enough time abroad to qualify for the foreign earned income exclusion. To meet this test, the individual must be physically present in a foreign country or countries for at least 330 full days during any 12-month period, which can be consecutive or non-consecutive days.
The Substantial Presence Test is a criterion used by the United States to determine if a foreign national qualifies as a resident for tax purposes based on their physical presence in the country. It involves calculating the number of days present in the U.S. over a three-year period, with a weighted formula applied to prior years to assess residency status.
