Understanding Social Security Numbers: Who Requires Them and Why

Social Security numbers (SSNs) are a critical component of the United States' social and economic infrastructure. This article delves into who is required to have a Social Security number, why it is necessary, and the implications of not having one.

Who is Required to Have a Social Security Number?

Many individuals in the United States either born here or in the process of obtaining residency are required to have a Social Security number. This includes:

Newborns and Non-U.S. Born Citizens: US hospitals typically assign SSNs to children born there, regardless of their parents' citizenship status. The mother is usually provided with the necessary paperwork shortly after the child's birth. Non-U.S. Citizens on a Green Card: Those with a green card who intend to work for pay in the US must obtain an SSN to become legally employed. Spouses and children accompanying them may also need SSNs or Individual Taxpayer Identification Numbers (ITINs) for tax purposes. Non-Immigrant Visa Holders: Anyone on a non-immigrant visa that permits work under certain conditions, such as an H-1B visa (only for the sponsoring employer) or an F-1 visa (limited to 20 hours a week on-campus employment), must obtain an SSN for legal employment. Similarly, their accompanying spouses and children will usually need SSNs or ITINs to be claimed as dependents.

Why Having an SSN is Important

Having a Social Security number for employment is crucial. Employers are required to minimize payroll taxes by withholding a portion of earned income from employees who have an SSN. Additionally, declaring dependents on tax returns necessitates the use of an SSN. Therefore, individuals with children born into their household should apply for an SSN as soon as possible.

Implications of Not Having a Social Security Number

The lack of a Social Security number can have significant implications:

Employment Barriers: Without an SSN, individuals are unable to secure lawful employment in the United States. Tax Filing Limitations: Individuals may face difficulties when attempting to file taxes, especially when claiming dependents. The IRS requires an SSN for tax purposes. Government Services: SSN is often required for government-issued services such as social security benefits, Medicaid, unemployment insurance, and official documentation.

Conclusion

Understanding who needs a Social Security number and why it is essential is crucial for individuals living in the United States. Whether you are a newborn, a non-U.S. citizen with a green card, or a non-immigrant visa holder, having an SSN is fundamental for employment, tax purposes, and access to various government services and benefits.
