Paying Taxes on Foreign Income and US Income in 2025

Factually stating, living as a US citizen abroad does not prevent you from your US tax duties. All in all, you must file an annual tax return if you are over the filing threshold – it’s obligatory. Additionally, you may be liable to pay US taxes, which we’ll get into below.

Any foreign-sourced income you make can be taxed at the same marginal rate as any other regular income being earned within the country.

To avoid double taxation – when the US and foreign country you live in both place tax on your income – the IRS allows expat tax benefits. $126,500 of foreign earned income for tax season 2024 (filing in 2025). Furthermore, the Foreign Tax Credit can be used as a credit for specific types of income – unique to each foreign country, allowing you to offset US income taxes with the income tax you paid to a foreign country

What Happens if You Made a Mistake when Filing?

The IRS Form 1040X can be your saving grace to amend a mistake via your federal tax form. Thus, this form can correct forms 1040, 1040-A, 1040-EZ, 1040-NR, or 1040-NR EZ. Plus, you can change the income amounts previously adjusted by the IRS and claim a carryback from a loss or unused credit.

Form 1040X allows you to file for an amendment within three years from the original due date you submitted your return. For example, if you made an error on your last tax return, you have until 2025 to make the necessary changes.

Additionally, the IRS uses a technological system to process tax returns. It can identify missing income, mathematical errors, required schedules, and more. So, if your tax forms have a mistake or two, the IRS system can adjust the income/numbers accordingly, and you will receive a notification that changes have been made. 

Then, let’s say you’ve missed filing a tax schedule. The IRS will notify you in two ways: It will send you a request to file the program or ignore your missing plan and process your return.
