This calculator is for educational and tax-estimation purposes only, such as using in planning for withholding via IRS forms 673 or W-4. It does not constitute tax, legal, or financial advice. It is not a substitute for consulting IRS publications, using full-featured tax software (for example, TurboTax), or obtaining advice from a qualified tax professional. U.S. international tax rules are complex and subject to change. However, this tool can be very helpful in checking against anything you received from an accountant or tax software. The target audience is an individual who may use the Foreign Earned Income Exclusion, such as a contractor for a US company that is based in Japan and meets FEIE criteria.

Why did I include some tax situations and not others? I aimed to create a simple interface that still addresses the most significant issues expats face when using the FEIE. I’ve seen tens of thousands of dollars in IRS overpayments and costly decisions driven by misunderstandings of individual tax situations. My hope is that this tool helps you build the knowledge needed to make better, more informed decisions well before tax preparation time.

In December 2025, the IRS published tax brackets, standard deductions, and various limits for tax years 2025 and 2026. However, most individual forms and instructions were not released yet. When a form does not exist, this estimator follows previous tax year procedures, incorporating any known tax law changes (OBBB). Note that because of variations in rounding styles and differences across IRS tax forms, tax tables, and worksheets, you can expect results from this estimator to vary by approximately by a few tens of dollars compared to other methods (for example, TurboTax). However, it's going to get the big things accurate and its purpose is education.
