Under U.S. income tax treaties with Canada and Germany, social security benefits paid by those countries to U.S. residents are treated for U.S. income tax purposes as if they were paid under the U.S. social security legislation. This means that such benefits are subject to the same rules for taxation as U.S.-issued Social Security benefits.
Tax Treatment for U.S. Residents
- Canadian or German social security benefits received by U.S. residents must be included in your total income for determining whether any portion is taxable.
- These benefits are reported on Form SSA-1099 or RRB-1099, and you must include the full amount from Box 5 on line 1 of Worksheet 1 in Publication 915 to determine if any portion is taxable.
- The taxable portion is determined by comparing your combined income (one-half of your benefits plus all other income, including tax-exempt interest) to your base amount for your filing status.
Base Amounts for 2025
- Single: $25,000
- Married filing jointly: $32,000
- Married filing separately (if lived apart for entire year): $0
- Head of household: $32,000
If your combined income exceeds the base amount, up to 85% of your benefits may be taxable. If it does not exceed the base amount, none of your benefits are taxable.
