Form 1040 is the most common tax form for all US citizens—whether living in the US or abroad. In this post, we’re going to look at the basic details of Form 1040 that every expat should know.
Form 1040 is the standard tax return for US individuals, regardless of where they live. This form is used to report:
There are a few variations of Form 1040, each with its own purpose.
Depending on the types of income you have to report, you may have to attach additional forms to your Form 1040, known as schedules. For example, self-employed taxpayers must attach Schedule C to their tax return to report any self-employment income.
Virtually every US citizen is required to file a Form 1040 tax return every year regardless of where they live. Whether you live in Tampa or Tokyo, you still have to report your income to Uncle Sam if it exceeds certain thresholds.
So what are those thresholds? That depends on your age and filing status. See the table below for the minimum income to file for 2022. (All amounts refer to traditional employment income.)
*Standard deductions generally increase a little each year.
If you are married and filing jointly, and one spouse is under 65 while the other is 65 or older, the minimum income to file is $26,450. (And no, that $5 for married filing separately isn’t a typo. That really is the filing threshold!)
As mentioned, the table above refers only to traditional employment income. If you receive $400 or more in self-employment income, you must file Form 1040 to report it. Self-employment income is income earned as a business owner and includes work done as a freelancer and contractor.
You may also have to file Form 1040 if you receive other non-traditional types of income, such as:
In other cases, you may need to file Form 1040 to claim certain tax benefits, such as a refund, even if you wouldn’t otherwise be required to file.
For most US citizens, Form 1040 is due on April 15 (April 18 in 2023). However, expats are granted an automatic two-month extension to June 15. If necessary, you can also request an additional filing extension to October 17.
An extension to file Form 1040 is not an extension to pay. Regardless of your extension, you will still have to estimate and pay your annual taxes by the original April deadline to avoid potential penalties.
Failing to file Form 1040 can result in severe penalties. These penalties vary depending on a few factors.
In addition to these penalties, you will also face penalties if you file Form 1040 but do not pay the taxes you owe by the April deadline. These penalties are much lower than a failure-to-file penalty, so it is always best to file even if you don’t think you can pay all of what you owe right away.
When you live in the US, tax day is simple: April 15th! When you move abroad, it’s not so straightforward! Learn about all the expat deadlines and extensions you need to know to file.
Before beginning the process of completing Form 1040, you will want to gather all relevant documents.
Once you have the right documents, it’s time to start on Form 1040 itself. Look at the example below.
Once you’ve gotten all the income and deductions associated with your return, you’ll be ready to start filling out Form 1040 for your US expat taxes. To better demonstrate the process of completing the form, let us introduce you to Brian Expat. Brian and his wife, Sarah, are US citizens and have lived in Pennsylvania all their lives. They got married in 2022 and have been living in Thailand ever since. They also have two small children, Kevin and Audra Expat.
Brian works for a Thai company that handles American clients and has been working there since January 1, 2022. Brian has been earning just over THB 4,000,000, which translates into $125,012 at the year’s average annual exchange rate. Sarah, on the other hand, does freelance writing from her home office while taking care of their young children, which earned Sarah $10,000. They have a savings account back in the US that generated $1,000 in interest income. Their last source of income in 2022 was the sale of their second property back in the US, which landed a gain of $30,000.
For deductible business expenses, Sarah completed an online Thai course that was administered by the US Department of Education. This cost $300 for six weeks and was work-related, as she is attempting to have articles published in Thai. She also has other expenses from her business, that total $1,000. Lastly, Brian is still paying back his loans for his education back in Pittsburgh, allowing him to deduct the $39 in interest that he paid.
With this information, we can successfully prepare their Form 1040 for their 2022 US expat taxes.
The first part of how to fill out 1040 is going to be completing the information section. This includes your name, spouse’s name (if filing jointly), and any dependents you may be claiming. Since Brian and Sarah are filing jointly this year, they will both be included in their section. Their children’s information is also provided in this 1040 example.
Assuming for the Tax Year 2022; they
Next, Brian and Sarah will report their income on their US expat taxes by using the appropriate tax documents from Brian’s employer, Sarah’s accountant, the sale of their property, and the bank statement proving the interest they earned.
Most of the income earned will be reported directly on the first page of Form 1040. Brian’s wages will be listed on Line 1, Wages salaries, tips, etc. Their interest income will be listed on Line 2b, Taxable Interest.
Because Brian and Sarah are both US citizens who have lived abroad the entire year, they are eligible for the Foreign Earned Income Exclusion (FEIE). The FEIE will apply to each of them separately. For 2022, the maximum amount of FEIE is $112,000 per qualifying person. Because of this, Brian will be eligible to exclude $112,000 of his $125,012 in wages, and Sarah will be able to exclude the entire $8,700 she earned from freelance writing. They will reflect this total ($120,700) FEIE on line 9 of Schedule 1 and also attach individual Forms 2555 to their return, which flows to their Form 1040 Line 8 reducing their income. In the same manner, Sarah’s deductible portion of self-employment tax (Schedule 1 Line 15), and Brian’s student loan interest (Schedule 1 Line 21), will flow to their Form 1040 Line 10, reducing their income as well.
Since Brian and Sarah are filing jointly in the 1040 tax form example, they are allowed a standard deduction of $25,100. This reduces their taxable income to $21,558 (line 15 of Form 1040).
Calculating your taxes owed on your US expat taxes can be intimidating, but the IRS provides you with useful tools to identify how much you owe. If you made less than $100,000, you can find your tax rate on pages 65 – 76 of the IRS’s Instructions for Form 1040. If you earned more than $100,000, use the tables found on page 77 of the IRS’s Instructions for Form 1040.
It is important to note that when you are claiming the Foreign Earned Income Exclusion, there is a special worksheet to complete to calculate your tax due for the year. This can be found on page 35 of the IRS’s Instructions for Form 1040.
For their total amount owed, Brian and Sarah can reduce their taxes with certain credits. As expats, they could claim a credit for foreign taxes on foreign source income. When the foreign earned income exclusion is claimed, the amount of foreign tax paid or accrued must be scaled down to reflect the portion of foreign source income that was excluded from income. Brian and Sarah paid $301 of Thai tax; however, after taking into account the foreign earned income exclusion and deductions, Brian and Sarah have no amounts of foreign tax credits to utilize for 2022. Although there is no available foreign tax credit, Brian and Sarah may utilize the child tax credit, a child tax credit of $3,234, to reduce their tax (shown on Form 1040, line 19).
Sarah is responsible for self-employment tax on her net business profits, which are accounted for on Schedule 2 (and calculated on Schedule SE).
After considering these additional credits and other taxes, their total amount due is $1,229, as seen on line 37 of Form 1040.
The last steps in finishing Form 1040 for US expat taxes are signing the form, filling out the preparer’s information (if necessary), and sending it to the appropriate agency with the necessary payment
Now that Brian and Sarah have completed their taxes for 2022, they only need to focus on staying compliant with the IRS moving forward. The best way to do so is to stay aware of deadlines for expats, keep up to date on information for completing the returns to come in the future (including prior-year tax returns), and keep up to date on annual changes in tax policies.
Form 1040 is a notoriously complicated tax form, and even a minor mistake could have major implications for your tax bill—especially as an expat. We recommend always consulting a qualified expat tax professional rather than attempting to complete and file this form on your own.
