Itemized Deductions Schedule A for Expats

What Are Itemized Deductions?

When filing your U.S. taxes, you have two main options: the standard deduction or itemized deductions. For U.S. citizens living abroad, itemized deductions can unlock significant savings — especially when your expenses exceed the standard deduction.
Common deductions include mortgage interest, charitable contributions, medical expenses, and state/local taxes (where applicable). But for expats, there are additional considerations, like foreign taxes paid and unreimbursed business expenses. Understanding which deductions you can claim is the first step toward minimizing your U.S. tax liability.

How U.S. Expats Can Claim Schedule A

To itemize deductions as an expat, you’ll need Schedule A of Form 1040. Key steps include:

Track all eligible expenses abroad

Keep detailed records of charitable donations, medical expenses, and any foreign taxes paid.

Consider FEIE and foreign tax credits

Some expenses may interact with the Foreign Earned Income Exclusion or credits, so plan carefully.

Maximize deductions unique to expats

Certain unreimbursed moving expenses, home office deductions, or foreign state taxes (if applicable) can make a difference.

Example: An expat paying foreign property taxes can potentially deduct these on Schedule A, lowering overall taxable income.

Common Mistakes to Avoid

Even seasoned expats sometimes misstep. Avoid these pitfalls:

  1. Forgetting to convert foreign currencies correctly 
  2. Claiming expenses not actually deductible under U.S. tax law
  3. Failing to track documentation for charitable contributions or medical expenses abroad

Correct documentation is essential — missing receipts can lead to denied deductions and IRS scrutiny.

Maximize Your Tax Savings

The best strategy is proactive:

Plan deductions before filing

Track throughout the year to ensure no opportunities are missed.

Combine deductions with credits strategically

Use FEIE, foreign tax credits, and itemized deductions together for maximum benefit.

Consult an expat tax professional

Navigating foreign deductions can be tricky, and the right guidance ensures compliance while minimizing your tax bill.
