Estimated Tax Calculator for US Expats
This calculator is designed to help you estimate payments under the safe harbor rules—generally 100% of your prior year’s US tax liability (or 110% if your adjusted gross income was over $150,000). If you meet one of these safe harbors, you won’t owe any penalties or interest, even if your estimated payments fall short of your actual tax liability for the year.
