Yes, Non-US citizens may need to report US Social Security benefits, but the tax rules vary. How Social Security benefits are taxed and reported depends on whether the individual is considered a resident alien or nonresident alien for US tax purposes. In some cases, tax treaties between the United States and another country may reduce or eliminate US tax on these benefits.
So if your US Social Security benefits are subject to US tax, and not enough tax was withheld, or the opposite, too much tax was withheld, a tax return may be needed

How Social Security Benefits Are Taxed for Nonresident Aliens
If a non-US citizen is classified as a nonresident alien for US tax purposes, special rules apply to Social Security benefits. Nonresident aliens generally report income using Form 1040-NR.
Under US tax law, 85% of Social Security benefits are treated as US-source Fixed, Determinable, Annual, or Periodical (FDAP) income. This amount may be subject to a 30% withholding tax unless an applicable tax treaty provides a reduced rate or exemption.
For example, if a nonresident alien receives $10,000 in Social Security benefits, up to $8,500 of those benefits may be subject to withholding.
How Social Security Benefits Are Taxed for Resident Aliens
A non-US citizen who qualifies as a resident alien follows different rules. Resident aliens generally report income using Form 1040, the same tax return used by US citizens.
Resident aliens report Social Security benefits on a standard US tax return using the same rules that apply to US citizens. Depending on their income, 0%, 50%, or up to 85% of Social Security benefits may be taxable.
Tax residency status, not citizenship, determines which rules apply.
How Tax Treaties Affect Social Security Benefits
The United States has income tax treaties with over 60 countries worldwide that may reduce or eliminate US tax on Social Security benefits.
Depending on the treaty, Social Security benefits may:
- Remain subject to standard withholding rules
- Be taxed at a reduced rate
- Be exempt from US tax
Because treaty provisions vary by country, taxpayers should review the treaty that applies to their country of residence or citizenship.
