Totalization agreements are international tax treaties that seek to eliminate dual taxation with regards to Social Security and Medicare taxes in the United States. These agreements are made in order to accommodate foreign workers who pay FICA taxes but receive no Social Security or Medicare benefits after reaching age 65. The agreements are made between the U.S. and other individual countries, and govern international taxpayers who earn money in the U.S. The goal of totalization agreements is to eliminate dual taxation on a foreigner's income made in the U.S. as well as provide proportional Social Security benefits for the same foreign workers. Issues considered to determine if a worker is covered under either Social Security and Medicare in the United States, or the social security system in a foreign country include where the worker resides and whether the employment in a foreign country is short-term or long-term. As of January 2025, the U.S. has 30 active totalization agreements.
In 1935, Congress passed the Social Security Act. The act established a taxpayer-funded old-age pension. [1] In the 1960s, Congress established Medicare, which provides taxpayer-funded health insurance to the elderly. [2] [3] In order to finance Social Security and Medicare, Congress passed the Federal Insurance Contributions Act, also known as FICA. [4] Under FICA tax policy as of December 2017, the act mandates 3 different types of payroll taxes that employees have withheld from their paychecks: a 6.2% Social Security tax, a 1.45% Medicare tax, and, starting in 2013, a 0.9% Medicare tax for workers who make over $200,000 a year. [5] Additionally, employers have to match any Social Security and Medicare taxes that their employees pay. [5] All that totals to roughly a 12% Social Security tax and a 3% Medicare tax as a percentage of an employee's base paycheck. [4]
A problem with the system of payroll taxes to fund old-age benefits is the effects of those taxes on foreign nationals. If someone from a foreign country works for a U.S. company in the U.S., that employee would have to pay FICA taxes. However, given that the worker is a foreign national, that worker is not eligible for U.S. old-age benefits, which only U.S. citizens or U.S. permanent residents are eligible for. [6] [7] That would be an unfair situation in that a foreign national would be paying into a system that they cannot derive benefit from. In addition, these nationals may also be subject to their home country's pension taxes, resulting in double taxation on the same income. Foreign residence can also result in gaps in pension benefits. [8] [9] The same problem of double taxation and a lack of benefits can also occur with U.S. citizens or permanent residents working abroad. [9] Totalization agreements seek to remedy this problem of double taxation, as well as to fill in gaps in multiple country's old-age benefit programs. [10] [8] [9] As of January 2025, the U.S. has entered into totalization agreements with 30 countries. [11]
Totalization agreements that the U.S. enters into with other countries generally all have a few key components. Overall, totalization agreements eliminate dual social security coverage of workers in the U.S. and the other country they are from or work in. This involves exempting a worker from either the U.S. or the other country's taxation and benefits program. Many rules govern which nation's social security system covers a worker. One rule, the territoriality rule specifies that a worker is subject to the laws of the country in which he/she is working in. This rule is active in all U.S. agreements. Under this rule, a German citizen working and residing in the U.S. would pay FICA taxes and would eventually be eligible for Social Security and Medicare benefits from the United States. [9]
Another rule, the detached-worker rule, governs foreign workers who are only temporarily stationed in the United States. A worker who has been temporarily transferred to work in the United States, for a period of up to five years, will remain subject to the social security system of his/her home country. This rule also applies if a worker goes from one foreign country to a different foreign country for an additional five years. The detached-worker rule is in all U.S. agreements with other countries except for its agreement with Italy. For example, if a worker from Germany is only temporarily stationed in the United States for a period of five years, that worker would not pay FICA taxes to the U.S. and would instead pay into the German social security system and eventually receive benefits from that system. [9]
Workers who are self-employed in a foreign country are also subject to totalization agreements. These workers are usually subject to social security coverage of their place of residence. For example, a self-employed U.S. citizen living in Sweden will be covered by the Swedish social security system. However, exceptions do exist with regards to this part of the system. [9]
Totalization agreements tolerate exceptions to the above rules in determining what social security system should govern a specific worker. If both countries agree to make an exception for an individual worker, then the country that agreed to cover the specific worker will accordingly cover that worker. An example of an exception would be if a short-term stay in a country was extended a few months over the five-year maximum allotted for the application of the detached-worker rule. An agreement between the two countries could be made to ignore the extra three months the worker spent in the foreign country. That would prevent the worker in question from being subject to taxes from the country he/she works in. Instead, that worker would continue to be subjected to the social security system of his/her home country. [9]
The U.S. determines what totalization benefits a foreign national can receive based on how long that foreign national has been in the country and how long that foreign national has worked in his/her home country. The U.S. has a threshold for the time needed to work in order to receive full Social Security and Medicare benefits. With countries it has entered into a totalization agreement with, the U.S. will count foreign time worked towards the threshold. If the combined total exceeds the threshold, the U.S. will then pay partial payments to the recipients. [9]
While the United States uses tax treaties in order to manage the social security coverage with foreign nations, other regions of the world do things differently. For example, the European Union has a system in which workers may pay taxes to a multitude of member nations' systems. The system will then total all the contributions a worker made into the system. A worker will then be granted full social security benefits based on total contributions made throughout the continent. [10]
The United States has separate federal, state, and local governments with taxes imposed at each of these levels. Taxes are levied on income, payroll, property, sales, capital gains, dividends, imports, estates and gifts, as well as various fees. In 2020, taxes collected by federal, state, and local governments amounted to 25.5% of GDP, below the OECD average of 33.5% of GDP.
In the United States, Social Security is the commonly used term for the federal Old-Age, Survivors, and Disability Insurance (OASDI) program and is administered by the Social Security Administration (SSA). The Social Security Act was passed in 1935, and the existing version of the Act, as amended, encompasses several social welfare and social insurance programs.
The Federal Old-Age and Survivors Insurance Trust Fund and Federal Disability Insurance Trust Fund are trust funds that provide for payment of Social Security benefits administered by the United States Social Security Administration.
A regressive tax is a tax imposed in such a manner that the tax rate decreases as the amount subject to taxation increases. "Regressive" describes a distribution effect on income or expenditure, referring to the way the rate progresses from high to low, so that the average tax rate exceeds the marginal tax rate.
A pay-as-you-earn tax (PAYE), or pay-as-you-go (PAYG) in Australia, is a withholding of taxes on income payments to employees. Amounts withheld are treated as advance payments of income tax due. They are refundable to the extent they exceed tax as determined on tax returns. PAYE may include withholding the employee portion of insurance contributions or similar social benefit taxes. In most countries, they are determined by employers but subject to government review. PAYE is deducted from each paycheck by the employer and must be remitted promptly to the government. Most countries refer to income tax withholding by other terms, including pay-as-you-go tax.
Payroll taxes are taxes imposed on employers or employees. They are usually calculated as a percentage of the salaries that employers pay their employees. By law, some payroll taxes are the responsibility of the employee and others fall on the employer, but almost all economists agree that the true economic incidence of a payroll tax is unaffected by this distinction, and falls largely or entirely on workers in the form of lower wages. Because payroll taxes fall exclusively on wages and not on returns to financial or physical investments, payroll taxes may contribute to underinvestment in human capital, such as higher education.
The Federal Insurance Contributions Act is a United States federal payroll tax payable by both employees and employers to fund Social Security and Medicare—federal programs that provide benefits for retirees, people with disabilities, and children of deceased workers.
An independent contractor is a person, business, or corporation that provides goods or services under a written contract or a verbal agreement. Unlike employees, independent contractors do not work regularly for an employer but work as required, when they may be subject to law of agency. Independent contractors are usually paid on a freelance basis. Contractors often work through a limited company or franchise, which they themselves own, or may work through an umbrella company.
Double taxation is the levying of tax by two or more jurisdictions on the same income, asset, or financial transaction.
Three key types of withholding tax are imposed at various levels in the United States:
The Social Security debate in the United States encompasses benefits, funding, and other issues. Social Security is a social insurance program officially called "Old-age, Survivors, and Disability Insurance" (OASDI), in reference to its three components. It is primarily funded through a dedicated payroll tax. During 2015, total benefits of $897 billion were paid out versus $920 billion in income, a $23 billion annual surplus. Excluding interest of $93 billion, the program had a cash deficit of $70 billion. Social Security represents approximately 40% of the income of the elderly, with 53% of married couples and 74% of unmarried persons receiving 50% or more of their income from the program. An estimated 169 million people paid into the program and 60 million received benefits in 2015, roughly 2.82 workers per beneficiary. Reform proposals continue to circulate with some urgency, due to a long-term funding challenge faced by the program as the ratio of workers to beneficiaries falls, driven by the aging of the baby-boom generation, expected continuing low birth rate, and increasing life expectancy. Program payouts began exceeding cash program revenues in 2011; this shortfall is expected to continue indefinitely under current law.
Tax withholding, also known as tax retention, pay-as-you-earn tax or tax deduction at source, is income tax paid to the government by the payer of the income rather than by the recipient of the income. The tax is thus withheld or deducted from the income due to the recipient. In most jurisdictions, tax withholding applies to employment income. Many jurisdictions also require withholding taxes on payments of interest or dividends. In most jurisdictions, there are additional tax withholding obligations if the recipient of the income is resident in a different jurisdiction, and in those circumstances withholding tax sometimes applies to royalties, rent or even the sale of real estate. Governments use tax withholding as a means to combat tax evasion, and sometimes impose additional tax withholding requirements if the recipient has been delinquent in filing tax returns, or in industries where tax evasion is perceived to be common.
The United States federal government and most state governments impose an income tax. They are determined by applying a tax rate, which may increase as income increases, to taxable income, which is the total income less allowable deductions. Income is broadly defined. Individuals and corporations are directly taxable, and estates and trusts may be taxable on undistributed income. Partnerships are not taxed, but their partners are taxed on their shares of partnership income. Residents and citizens are taxed on worldwide income, while nonresidents are taxed only on income within the jurisdiction. Several types of credits reduce tax, and some types of credits may exceed tax before credits. Most business expenses are deductible. Individuals may deduct certain personal expenses, including home mortgage interest, state taxes, contributions to charity, and some other items. Some deductions are subject to limits, and an Alternative Minimum Tax (AMT) applies at the federal and some state levels.
The United States budget comprises the spending and revenues of the U.S. federal government. The budget is the financial representation of the priorities of the government, reflecting historical debates and competing economic philosophies. The government primarily spends on healthcare, retirement, and defense programs. The non-partisan Congressional Budget Office provides extensive analysis of the budget and its economic effects. CBO estimated in February 2024 that Federal debt held by the public is projected to rise from 99 percent of GDP in 2024 to 116 percent in 2034 and would continue to grow if current laws generally remained unchanged. Over that period, the growth of interest costs and mandatory spending outpaces the growth of revenues and the economy, driving up debt. Those factors persist beyond 2034, pushing federal debt higher still, to 172 percent of GDP in 2054.
The marriage penalty in the United States refers to the higher taxes required from some married couples with both partners earning income that would not be required by two otherwise identical single people with exactly the same incomes. There is also a marriage bonus that applies in other cases. Multiple factors are involved, but in general, in the current U.S. system, single-income married couples usually benefit from filing as a married couple, while dual-income married couples are often penalized. The percentage of couples affected has varied over the years, depending on shifts in tax rates.
The history of taxation in the United States begins with the colonial protest against British taxation policy in the 1760s, leading to the American Revolution. The independent nation collected taxes on imports ("tariffs"), whiskey, and on glass windows. States and localities collected poll taxes on voters and property taxes on land and commercial buildings. In addition, there were the state and federal excise taxes. State and federal inheritance taxes began after 1900, while the states began collecting sales taxes in the 1930s. The United States imposed income taxes briefly during the Civil War and the 1890s. In 1913, the 16th Amendment was ratified, however, the United States Constitution Article 1, Section 9 defines a direct tax. The Sixteenth Amendment to the United States Constitution did not create a new tax.
Due to the absence of the tax code in Argentina, the tax regulation takes place in accordance with separate laws, which, in turn, are supplemented by provisions of normative acts adopted by the executive authorities. The powers of the executive authority include levying a tax on profits, property and added value throughout the national territory. In Argentina, the tax policy is implemented by the Federal Administration of Public Revenue, which is subordinate to the Ministry of Economy. The Federal Administration of Public Revenues (AFIP) is an independent service, which includes: the General Tax Administration, the General Customs Office and the General Directorate for Social Security. AFIP establishes the relevant legal norms for the calculation, payment and administration of taxes:
Taxation in Puerto Rico consists of taxes paid to the United States federal government and taxes paid to the Government of the Commonwealth of Puerto Rico. Payment of taxes to the federal government, both personal and corporate, is done through the federal Internal Revenue Service (IRS), while payment of taxes to the Commonwealth government is done through the Puerto Rico Department of Treasury.
In general, the United States federal income tax is progressive, as rates of tax generally increase as taxable income increases, at least with respect to individuals that earn wage income. As a group, the lowest earning workers, especially those with dependents, pay no income taxes and may actually receive a small subsidy from the federal government.
In the United States, the combination of payroll taxes withheld from a household employee and the employment taxes paid by their employer are commonly referred to as the nanny tax. Under US law, any family or individual that pays a household employee more than a certain dollar amount per year must withhold and pay Social Security and Medicare taxes, also known as FICA. The law mandates that all domestic workers, such as cooks, nannies, housekeepers and gardeners, are subject to the nanny tax. Federal unemployment insurance taxes must also be paid if the household pays any number of employees a total of $1,000 or more in a calendar quarter. State unemployment insurance taxes have the same requirement with the exceptions of California ($750), New York ($500), and Washington, D.C. ($500), which have lower thresholds.
