How should I approach U.S. expat tax planning to reduce what I owe while living abroad?

Effective U.S. expat tax planning starts with matching your situation to the best double-taxation relief (FEIE vs FTC), tracking foreign taxes paid, timing income and deductions strategically, and coordinating U.S. rules with your country of residence. Small structural choices often matter more than the rate differential.

Core planning moves to evaluate every year:

• FEIE vs FTC decision: FEIE is simpler for low-tax countries; FTC is usually better in high-tax countries and preserves retirement contribution capacity
• Foreign Housing Exclusion: stacks with FEIE to shelter additional income in expensive cities
• Income timing: delay bonuses or capital gains into a year when you expect a lower U.S. bracket
• Retirement contributions: only possible with FTC (or partial-FEIE) plus taxable compensation
• Entity structure: U.S. LLC vs foreign corporation vs sole proprietor affects SE tax and international forms

Structural planning is worth revisiting annually:

Documents to maintain year-round:

• Day count log for FEIE
• Foreign tax paid records by income category
• Foreign account statements for FBAR and 8938
• Receipts and records for business expenses, housing costs
• Property basis records with currency conversion notes

Bringing a year-end review together with a CPA familiar with your country of residence is typically the highest-leverage move.
