Estimated Taxes for Expats – How To Make Payments Online and When

IRS Estimated Taxes

The United States income tax system is a pay-as-you-go tax system, which means that you must pay income tax as you earn or receive your income during the year. You can do this either through withholding or by making payments for estimated taxes.

Estimated taxes are quarterly payments made to the IRS during the year. These payments cover U.S. tax on income that does not have enough federal tax withheld.

For expats, this issue often comes up when you earn money from foreign employers, freelance work, rental properties, investments, or business profits. If no U.S. employer withholds federal income tax from that income, you may need to make estimated tax payments yourself.

The IRS uses Form 1040-ES, Estimated Tax for Individuals, to help individual taxpayers calculate and pay estimated tax. You do not always need to mail the form. In many cases, you can make the payment online and select Form 1040-ES as the payment type.

Who Needs To Pay Estimated Taxes As An Expat?

The Internal Revenue Service (IRS) generally requires you to make quarterly estimated tax payments if both of the following apply:

• You expect to owe at least $1,000 in federal tax for the year after subtracting federal tax withholding and refundable credits; and
• You expect your federal withholding and refundable credits to be less than the smaller of:
  • 90% of the tax shown on your current-year federal tax return; or
  • 100% of the tax shown on your prior-year federal tax return, as long as that return covered all 12 months.

Please note: These percentages may be different if you are a farmer, fisherman, or higher income taxpayer.
You do not have to pay estimated tax for the current year if you meet all three of the following conditions.

1. You had no tax liability for the prior year,
2. You were a U.S. citizen or resident for the whole year and
3. Your prior tax year covered a 12 month period.

Common situations where expats may need to pay estimated taxes include:

• You work as a freelancer or independent contractor abroad.
•  You own a business or receive pass-through income.
• You work for a foreign employer that does not withhold U.S. tax.
•  You receive rental income from U.S. or foreign property.
• You earn dividends, interest, or capital gains.
• You receive pension, retirement, or Social Security income without enough withholding.
• You claim the Foreign Earned Income Exclusion but still owe self-employment tax or tax on other income.

Do Expats Get Different Estimated Tax Rules?

No. Expats follow the same federal estimated tax rules as U.S. taxpayers living stateside.

What changes is the calculation.

As an expat, you may qualify for tax benefits that reduce your U.S. income tax. The two most common benefits are the Foreign Earned Income Exclusion and the Foreign Tax Credit.

The Foreign Earned Income Exclusion lets qualifying taxpayers exclude a set amount of foreign earned income from U.S. income tax. The Foreign Tax Credit can reduce U.S. tax when you pay income tax to a foreign country on the same income.

These benefits can reduce or remove your need for estimated tax payments. However, they do not solve every case. You may still owe U.S. tax if you earn more than the exclusion amount, live in a low-tax country, receive investment income, own rental property, or work for yourself.

Why Self-Employed Expats Need Special Attention

Self-employed expats often face the biggest estimated tax risk.

The reason is simple. The Foreign Earned Income Exclusion can reduce regular federal income tax, but it does not remove self-employment tax. Self-employment tax covers Social Security and Medicare tax.

For example, you may qualify to exclude most or all of your foreign earned income from income tax. But if you report net self-employment income, you may still owe U.S. self-employment tax on that profit unless a totalization agreement or other rule changes the result.

How To Calculate The Amount of Federal Quarterly Estimated Tax Payments

To calculate your estimated tax, estimate your adjusted gross income, taxable income, deductions, credits, exclusions, and total tax for the year. Your prior-year federal tax return can serve as a starting point, but update the numbers for any major changes, such as new freelance income, rental income, investment gains, foreign taxes paid, or expat tax benefits.

The Form 1040-ES includes an Estimated Tax Worksheet that can help you calculate your payment amount. You do not need a perfect estimate, but you should pay enough during the year to reduce the risk of underpayment penalties.

The IRS offers two common safe harbor methods.

The prior-year method often works well because you already know last year’s total tax. However, the current-year method may fit better if your income dropped or your tax situation changed.

For expats, the calculation should also include foreign income, self-employment tax, rental income, investment income, and any expected Foreign Earned Income Exclusion or Foreign Tax Credit.

What If Your Income Changes During The Year?

Many expats do not earn income evenly. Freelancers may have strong and slow months. Business owners may receive large payments in one quarter. Investors may sell assets later in the year.

If your income changes during the year, equal quarterly payments may not match your actual tax exposure. In that case, you may use the annualized income installment method. This method calculates the required payment for each period based on the income you actually earned during that period. It can help reduce penalties when your income arrives unevenly.

You report this calculation on Form 2210 when needed. Form 2210 helps determine whether you owe an underpayment penalty and whether an exception or waiver may apply.

When Are Estimated Tax Payments Due?

For estimated tax purposes, the year is divided into four payment periods. Each period has a specific payment due date. If you do not pay enough tax by the due date of each of the payment periods, you may be charged a penalty even if you are due a refund when you file your income tax return.

Below is a table that lists the filing due dates for quarterly estimated tax payments for each of these payment periods:

Payment	Payment Period	Due Date
Q1	January 1 to March 31, 2026	April 15, 2026
Q2	April 1 to May 31, 2026	June 15, 2026
Q3	June 1 to August 31, 2026	September 15, 2026
Q4	September 1 to December 31, 2026	January 15, 2027

If a due date falls on a weekend or federal holiday, the deadline moves to the next business day.

The second payment period covers only two months. That often looks odd, but it follows the IRS estimated tax schedule.

Do Expats Get Extra Time To Pay Estimated Taxes?

No. The automatic two-month filing extension for U.S. taxpayers abroad does not extend estimated tax payment deadlines.

Many expats know they may have until June 15 to file their federal income tax return. That filing extension does not move the April estimated tax deadline, and it does not remove interest or penalties for late or insufficient payments.

You should treat estimated tax deadlines as separate from filing deadlines. If you owe estimated tax, pay by the quarterly due date.

How To Pay Estimated Taxes Online As An Expat

You have several ways to pay estimated taxes online. The best method depends on whether you have a U.S. bank account, how close you are to the deadline, and whether you need payment history inside an IRS account.

When paying estimated taxes IRS online, always check three details before submitting:

• Payment reason: Estimated Tax
• Form: 1040-ES
• Tax year: The year you are paying toward

Selecting the wrong tax year can cause problems. For example, a 2026 estimated tax payment applies to your 2026 tax liability, which you file in 2027. It does not apply to your 2025 return unless you choose that year for a different payment reason.

Option One: Pay With IRS Direct Pay

IRS Direct Pay works well if you have a U.S. checking or savings account. You do not need to create an account. You enter your identity information, choose the payment type, enter your bank details, and submit the payment.

To pay Form 1040-ES through IRS Direct Pay:

1. Go to IRS Direct Pay.
2. Choose “Estimated Tax” as the reason for payment.
3. Select “1040-ES” as the form.
4. Choose the correct tax year.
5. Enter the payment amount.
6. Enter your U.S. bank routing and account numbers.
7. Review the payment details before submitting.
8. Save the confirmation number.

Direct Pay works best for expats who still maintain a U.S. bank account and want to avoid card processing fees.

Option Two: Pay Through An IRS Online Account

An IRS Online Account gives you more payment visibility than Direct Pay alone. You can view balances, check payment history, make payments, and manage certain account details. This option helps if you want a clearer record of your IRS payments.

However, you need to verify your identity before using the account. Some expats find this step slower from abroad, especially if their phone number, mailing address, or identification documents do not match the IRS verification process easily.

Once set up, the account can help you track payments and reduce recordkeeping mistakes.

Option Three: Pay By Debit Or Credit Card

A debit or credit card payment can help if you do not have a U.S. bank account. The IRS uses approved payment processors for card payments. Fees apply, and the fee depends on the processor and card type. The IRS does not keep that processing fee.

Card payments can work well for last-minute payments or expats who cannot access Direct Pay. However, the fee can become expensive on larger balances.

Before paying, confirm that you selected the right payment type, form, and tax year. Save both the IRS or processor confirmation and your card receipt.

Option Four: Pay By International Wire

An international wire may work if you do not have a U.S. bank account or a usable card. This method requires more care. Your bank must send the payment in U.S. dollars and include the correct IRS payment information. Processing delays, bank cutoffs, currency conversion, and intermediary bank issues can all affect timing.

Use this method only when you understand the wire instructions and can send the payment early enough to meet the deadline.

For expats, wire transfers work better for larger payments than small quarterly amounts, because bank fees can add up quickly.

Option Five: Pay By Mail With Form 1040-ES

You can still mail a check or money order with a Form 1040-ES payment voucher. For expats, this method usually creates the most risk. International mail can run slowly, and tracking can prove difficult. If the payment arrives late, the IRS may treat it as late even if you mailed it before the deadline.

If you mail a payment, use the current Form 1040-ES voucher and the correct IRS address for your location. Keep proof of mailing and a copy of the voucher. In most cases, online payment works better.

Can Expats Still Use EFTPS?

Some taxpayers can still use the Electronic Federal Tax Payment System, known as EFTPS.

However, this option changed for individuals. New individual taxpayers can no longer create new EFTPS accounts. Individual taxpayers who already enrolled before the cutoff may still use the system for now, but most new individual users should use IRS Direct Pay or an IRS Online Account instead.

Businesses may still use EFTPS for certain payments.

Payment Methods For Expats Compared

There are a variety of options for making quarterly estimated tax payments:

What Happens If You Miss An Estimated Tax Payment?

If you miss an estimated tax payment, pay as soon as you can. The IRS calculates underpayment penalties by payment period. That means a late Q1 payment can still create a penalty even if you pay more in Q2. A later payment may reduce the amount that continues to accrue, but it does not automatically erase the earlier shortfall.

Do not wait until you file your return if you already know you underpaid. Paying late usually costs less than waiting several months. You may also need Form 2210 when you file your tax return. This form can help calculate the penalty or show that you qualify for an exception.
