If you are a U.S. citizen or resident living or traveling outside the United States, you are generally required to file income tax returns in the same way as those residing in the United States. However, the special rules explained in the following discussions may apply to you.
Most individual tax returns cover a calendar year, January through December. The regular due date for these tax returns is April 15 of the following year. If April 15 falls on a Saturday, Sunday, or legal holiday, your tax return is considered timely filed if it is filed by the next business day that is not a Saturday, Sunday, or legal holiday. If you get an extension, you are allowed additional time to file and, in some circumstances, pay your tax. You must pay interest on any tax not paid by the regular due date.
Your return is considered filed on time if it is postmarked by the U.S. Postal Service, or dated by a designated delivery service, on or before the due date (including extensions). See your tax form instructions for a list of private delivery services that have been designated by the IRS to meet this “timely mailing as timely filing/paying” rule for tax returns and payments.
If your return is filed late, the postmark or delivery service date does not determine the date of filing. In that case, your return is considered filed when it is received by the IRS.
You may be able to get an extension of time to file your return and pay your tax.
You must file Form TD F 90-22.1 if at any time during the year you had an interest in, or signature or other authority over, a bank account, securities account, or other financial account in a foreign country. This applies if the combined assets in the account(s) were more than $10,000. Do not include accounts in a U.S. military banking facility operated by a U.S. financial institution.
File the completed form, by June 30 of the following year, with the Department of the Treasury at the address shown on that form. Do not attach it to Form 1040. If you are required to file Form TD F 90-22 but do not do so, you may have to pay a penalty of up to $10,000 (more if the failure to file is willful).
If you are a U.S. citizen or resident with income from sources outside the United States, you must report all that income on your tax return unless it is exempt by U.S. law. This applies to earned income (such as wages) as well as unearned income (such as interest, dividends, and capital gains).
Most payments received by U.S. Government civilian employees for working abroad, including pay differentials, are taxable. However, certain foreign areas allowances, cost of living allowances, and travel allowances are tax free. The following discussions explain the tax treatment of allowances, differentials, and other special pay you receive for employment abroad.
-
Post differentials,
-
Special incentive differentials, and
-
Danger pay.
-
Title I, chapter 9, of the Foreign Service Act of 1980.
-
Section 4 of the Central Intelligence Act of 1949, as amended.
-
Title II of the Overseas Differentials and Allowances Act.
-
Subsection (e) or (f) of the first section of the Administrative Expenses Act of 1946, as amended, or section 22 of that Act.
-
Certain repairs to a leased home,
-
Education of dependents in special situations,
-
Motor vehicle shipment,
-
Separate maintenance for dependents,
-
Temporary quarters,
-
Transportation for medical treatment, and
-
Travel, moving, and storage.
-
If you are a volunteer leader, allowances paid to your spouse and minor children while you are training in the United States.
-
The part of living allowances designated by the Director of the Peace Corps as basic compensation. This is the part for personal items such as domestic help, laundry and clothing maintenance, entertainment and recreation, transportation, and other miscellaneous expenses.
-
Leave allowances.
-
Readjustment allowances or “termination payments.”
Example.
Gary Carpenter, a Peace Corps volunteer, gets $175 a month during his period of service, to be paid to him in a lump sum at the end of his tour of duty. Although the allowance is not available to him until the end of his service, Gary must include it in his income on a monthly basis as it is credited to his account.
Some other income items that may apply to U.S. Government civilian employees stationed abroad are discussed in this section.
Deductions that may be of special interest to you are discussed here. They include travel expenses, transportation expenses, and other expenses connected to your employment.
Subject to certain limits, you can deduct your unreimbursed ordinary and necessary expenses of traveling away from home in connection with the performance of your official duties. These expenses include such items as travel costs, meals, lodging, baggage charges, local transportation costs (such as taxi fares), tips, and dry cleaning and laundry fees.

-
Your duties require you to be away from the general area of your tax home substantially longer than an ordinary day's work.
-
You need to get sleep or rest to meet the demands of your work while away from home. This requirement is not satisfied by merely napping in your car.
| Year | Percentage | |||
| 2004–2005 | 70 | |||
| 2006–2007 | 75 | |||
| 2008 and later | 80 |
-
Certain air transportation workers (such as pilots, crew, dispatchers, mechanics, and control tower operators) who are under Federal Aviation Administration regulations.
-
Interstate truck operators and bus drivers who are under Department of Transportation regulations.
-
Certain railroad employees (such as engineers, conductors, train crews, dispatchers, and control operations personnel) who are under Federal Railroad Administration regulations.
-
Certain merchant mariners who are under Coast Guard regulations.
You can deduct allowable transportation expenses that are directly related to your official duties. Transportation expenses include the cost of transportation by air, rail, bus, or taxi, and the cost of driving and maintaining your car. They do not include expenses you have when traveling away from home overnight. Those expenses are deductible as travel expenses and are discussed earlier.
You may be able to deduct other unreimbursed expenses that are connected with your employment.
-
Maintains or improves skills needed in your present position, or
-
Meets the express requirements of your agency to keep your present position, salary, or status.
-
Is needed to enable you to meet minimum educational requirements for qualification in your present position,
-
Is a part of a program of study that can qualify you for a new position, or
-
Is for travel as a form of education.

-
You have a certificate from the Secretary of State attesting that the expenses were incurred for the benefit of the United States, and would be reimbursable under appropriate legislation if the agency had sufficient funds for these reimbursements.
-
The expenses, while specifically not reimbursable under State Department regulations, were ordinary and necessary business expenses incurred in the performance of your official duties.

If you claim a deduction for unreimbursed business expenses, you must keep timely and adequate records of all your business expenses.
For example, you must keep records and supporting evidence to prove the following elements about deductions for travel expenses (including meals and lodging while away from home).
-
The amount of each separate expense for travel away from home, such as the cost of your transportation, lodging, or meals. You may total your incidental expenses if you list them in reasonable categories such as daily meals, gasoline and oil, and taxi fares.
-
For each trip away from home, the dates you left and returned and the number of days spent on business.
-
The destination or area of your travel, described by the name of the city, town, or similar designation.
-
The business reason for your travel or the business benefit gained or expected to be gained from your travel.


As a U.S. Government employee, your business expense reimbursements are generally paid under an accountable plan and are not included in your wages on your Form W-2. If your expenses are not more than the reimbursements, you do not need to show your expenses or reimbursements on your return.
However, if you do not account to your employer for a travel advance or if you do not return any excess advance within a reasonable period of time, the advance (or excess) will be included in your wages on your Form W-2.

-
You are not reimbursed by your employer for any expenses. (Amounts your employer included in your wages on your Form W-2 are not considered reimbursements.)
-
If you claim car expenses, you use the standard mileage rate.
In addition to deductible business expenses, you may be entitled to deduct certain other expenses.
If you changed job locations or started a new job, you may be able to deduct the reasonable expenses of moving yourself, your family, and your household goods and personal effects to your new home. However, you cannot deduct any expenses for which you received a tax-free allowance as a U.S. Government employee.
To deduct moving expenses, your move must be closely related to the start of work and you must meet the distance test and the time test.
-
Moving household goods and personal effects (including packing, crating, in-transit storage, and insurance) of both you and members of your household, and
-
Transportation and lodging for yourself and members of your household for one trip from your former home to your new home (including costs of getting passports).

You may be able to claim other itemized deductions not connected to your employment.
Example.
Adam is an IRS employee working overseas who receives a $6,300 tax-free housing and utility allowance. During the year, Adam used the allowance, with other funds, to provide a home for himself. His expenses for this home totaled $8,400 and consisted of mortgage principal ($500), insurance ($400), real estate taxes ($1,400), mortgage interest ($4,000), and utility costs ($2,100). Adam did not have any other expenses related to providing a home for himself.
Adam must reduce his deductions for home mortgage interest and real estate taxes. He figures a reasonable way to reduce them is to multiply them by a fraction: its numerator is $6,300 (the total housing and utility allowance) and its denominator is $8,400 (the total of all payments to which the housing and utility allowance applies). The result is ¾. Adam reduces his otherwise allowable home mortgage interest deduction by $3,000 (the $4,000 he paid ×¾) and his otherwise allowable real estate tax deduction by $1,050 (the $1,400 he paid × ¾). He can deduct $1,000 of his mortgage interest ($4,000 - $3,000) and $350 of his real estate taxes ($1,400 - $1,050) when he itemizes his deductions.
-
The amount of each type of tax-free income you received, such as a tax-free housing allowance or tax-free representation allowance.
-
The amount of otherwise deductible expenses attributable to each type of tax-free income.
-
The amount attributable to each type of tax-free income that was not directly attributable to that type.
-
An explanation of how you determined the amounts not directly attributable to each type of tax-free income.
If you pay or accrue taxes to a foreign government, you generally can choose to either claim them as a credit against your U.S. income tax liability or deduct them as an itemized deduction when figuring your taxable income.

-
Your only foreign income is passive income, such as interest, dividends, and royalties.
-
The total of all your foreign taxes is not more than $300 ($600 for joint tax returns).
-
The foreign income and taxes are reported to you on a payee statement, such as Form 1099-DIV, Dividends and Distributions, or 1099-INT, Interest Income.
Example.
Dennis and Christina are married and live and work in Country X. Dennis works for the U.S. Government and Christina is employed by a private company. They pay income tax to Country X on Christina's income only.
Dennis and Christina file a joint tax return and exclude all of Christina's income. They cannot claim a foreign tax credit or take a deduction for the taxes paid to Country X.
