Equity Compensation Abroad: U.S. Tax, Sourcing, and Reporting

What this guide covers

Equity compensation is not a single tax event. Depending on the instrument and the facts, it can involve grant, vesting, exercise, settlement, shares withheld, transfer, sale, employer withholding, foreign tax, and prior U.S. reporting — each with potentially different tax consequences.

This guide walks through the complete grant-to-sale timeline for U.S. taxpayers with equity awards earned across countries. It covers RSUs and restricted stock, statutory and nonstatutory stock options, ESPP shares, and private-company awards. It explains sourcing by work location rather than employer location, the distinction between compensation income and sale gain, and the separate questions of FEIE eligibility, foreign tax credit, withholding, and information reporting.

Use the equity compensation abroad consultation to organize your specific facts before filing.

Start with the instrument, not the employer's country

The first step is identifying what kind of award you have. The label matters because different instruments trigger different rules.

RSU (Restricted Stock Unit): A promise to deliver shares at vesting, subject to service or performance conditions. Ordinary income generally arises at vesting in the fair market value of the shares. No taxable event occurs at grant.

Restricted stock: Actual shares transferred to the employee but potentially subject to forfeiture or other restrictions. If the stock is substantially nonvested, compensation generally is recognized when the stock becomes substantially vested, based on its fair market value at that time minus any amount paid for it. A timely Section 83(b) election can instead cause the employee to include the property's value, less any amount paid, in income when the property is transferred.

ISO (Incentive Stock Option) / NSO (Nonqualified Stock Option): An option to purchase shares at a fixed price. A qualifying ISO generally does not create regular federal income tax at grant or exercise, although exercise can create an alternative minimum tax adjustment. A nonstatutory option can create compensation income when exercised if it did not have a readily determinable fair market value when granted. For cross-border employees, compensation attributable to an option must be analyzed separately from any later capital gain, including where the services that earned the compensation were performed.

ESPP (Employee Stock Purchase Plan): An employee stock purchase plan can allow employees to acquire shares through an option, often at a discount. For a qualifying Section 423 plan, exercising the option generally does not itself create regular taxable income. The later disposition of the shares can create ordinary compensation income as well as capital gain or loss, and the result depends in part on whether the statutory holding-period requirements are satisfied.

Phantom equity, SARs, carried interest: These instruments are not stock and do not give rise to the same events. Each requires separate analysis of when income arises, how it is characterized, and what reporting applies.

The employer's country of incorporation, the broker's location, or the grant currency does not change which instrument rules apply to a U.S. person.

The grant-to-sale timeline

Equity compensation earned across countries creates a sequence of events. Track each one separately. Each event can have a different tax consequence, source, withholding obligation, and reporting requirement.

Section 83(b) exception: If eligible substantially nonvested property is transferred and the taxpayer makes a timely Section 83(b) election, compensation is generally measured at transfer rather than waiting until the property substantially vests. Keep the election and proof of timely filing with the award records.

Sourcing compensation by work location

The U.S. does not source equity compensation income based on where the employer is incorporated, where the payroll is processed, or which currency the grant is denominated in. It sources by where the services that earned the compensation were performed.

For equity awards tied to a service or vesting period, compensation sourcing generally requires identifying the services that earned the compensation and where those services were performed. The relevant service period and allocation method can differ by instrument, including for options, RSUs, restricted stock, and ESPP compensation. When services are performed partly inside and partly outside the United States, the compensation may require allocation rather than being assigned entirely to the employer's country.

For options, the same principle applies: the income from a stock option is sourced by where the services were performed during the service period that gave rise to the option benefit.

If your work location changed during a vesting period — you moved from one country to another, or you traveled extensively — the sourcing may need to reflect that split. The specific allocation method depends on the facts and the applicable year.

This is one of the most common errors in cross-border equity reporting: treating the employer's location as the source rather than tracking where the work was actually performed.

Compensation income vs. sale gain and basis

A critical distinction runs through the entire equity timeline: the amount included as compensation income and the basis created by that inclusion are not the same as the proceeds from a later sale.

Example: You vest 1,000 RSUs when the shares are worth $50 each. Ordinary income of $50,000 is reported on your Form W-2. Your cost basis in those 1,000 shares is $50 per share. When you sell the shares later for $80 each, the gain is $30,000 — a capital gain, not compensation. The character of that gain (long-term or short-term) depends on your holding period from vest date.

This distinction matters across every stage: vesting creates compensation income; a sale creates capital gain or loss. The sale of shares acquired through employment is not earned income merely because the underlying instrument was granted as compensation.

The basis created at vesting or exercise becomes the cost basis for calculating gain or loss on a subsequent sale. A foreign broker's location or a foreign custodian does not change how basis is calculated or how sale gain is determined.

FEIE and equity compensation

Equity compensation that constitutes earned income may be considered for the Foreign Earned Income Exclusion, but only if it meets the requirements: the income must be for services performed abroad, the taxpayer must have a foreign tax home, and the applicable qualification test must be satisfied.

A stock sale gain — the appreciation between vesting value and sale proceeds — is not earned income and cannot be excluded under FEIE, regardless of how the underlying shares were received.

Equity compensation from a U.S. employer for services performed partly in the U.S. and partly abroad may require allocation. A foreign employer or a foreign payroll may create different facts than a U.S. employer, but the core question remains: where were the services performed that earned the award?

For detailed FEIE qualification analysis, see the FEIE Guide.

Foreign Tax Credit and equity income

If foreign tax was withheld or paid on equity compensation income — through payroll withholding, a local tax on vesting proceeds, or withholding on sale — that tax may be creditable on Form 1116, subject to source, category, timing, and limitation rules.

Whether a foreign levy qualifies for the foreign tax credit depends on the applicable U.S. creditability rules. Social insurance contributions, pension levies, and other local charges require separate analysis, and foreign withholding does not automatically establish that a tax is creditable.

When equity income is sourced partly to the U.S. and partly to a foreign country, the creditable foreign taxes must be allocated consistently with the income sourcing. The FTC limitation may apply differently to equity compensation than to wage income.

For FTC mechanics, see the Foreign Tax Credit Guide.

Forms and information reporting

Employer / corporation information returns:

• Form 3921: A corporation generally files Form 3921 when it transfers stock to a person pursuant to that person's exercise of an incentive stock option described in Section 422(b). The form reports information including the grant date, exercise date, exercise price, fair market value at exercise, and number of shares transferred. The corporation also furnishes the required statement to the employee.
• Form 3922: A corporation generally files Form 3922 for certain first transfers of legal title to shares acquired through the exercise of an option under a Section 423 employee stock purchase plan. The corporation furnishes the required statement to the employee.

These are corporation-filed information returns, not forms that an employee ordinarily attaches to Form 1040. Employees should retain Forms 3921 and 3922 they receive because the information can be important for determining basis, holding periods, AMT consequences, and the tax treatment of a later disposition.

Employee-side forms:

• Form W-2: Wages from equity compensation are reported in Box 1, 3, 5 (and Box 12 with appropriate codes) of the Form W-2 received from the employer. This is the primary reporting vehicle for compensation income.
• Form 8949 and Schedule D: Report the sale or exchange of stock. The basis from vesting or exercise is carried to these forms.
• Form 6251: Alternative minimum tax may apply to ISO exercises and certain other equity events.
• Form 1116: If claiming FTC for foreign taxes on equity income.
• Form 2555: If FEIE is claimed on any portion of equity compensation.
• Form 8938: Depending on the applicable filing threshold and the taxpayer's facts, foreign financial accounts and certain other specified foreign financial assets may have to be reported on Form 8938. When foreign stock or securities are held through a reportable foreign financial account, the account generally is reported rather than separately listing each security held inside it.
• FBAR (FinCEN 114): A U.S. person generally must file an FBAR when the aggregate value of foreign financial accounts in which the person has a financial interest or signature or other authority exceeds $10,000 at any time during the calendar year. A securities or brokerage account maintained at a foreign financial institution can be a reportable foreign financial account. The account is reported; securities held inside the account are not separately reported on the FBAR.

A foreign broker does not automatically create an FBAR or Form 8938 obligation. The analysis depends on account ownership, maximum value, asset type, and whether the arrangement meets the definition of a foreign financial account or a specified foreign financial asset.

Private-company awards

Awards in private companies — stock options, phantom equity, or restricted stock in a company whose shares are not publicly traded — add complexity.

No market price exists for valuation. The company may provide a 409A valuation or a recent round valuation. The IRS may challenge the valuation if it appears artificially low or if the 409A is stale.

Restrictions on transfer, vesting conditions, repurchase rights, and buy-sell agreements can affect when income is recognized and how basis is established. When eligible substantially nonvested property is transferred, a timely Section 83(b) election generally causes the employee to include the property's fair market value at transfer, less any amount paid for it, in compensation income rather than waiting until the property substantially vests. The election has important basis, holding-period, forfeiture, and cash-tax consequences and should not be described simply as a way to "lock in" a low valuation.

Liquidity events — a sale, IPO, or redemption — create the sale event and determine gain or loss. Before a liquidity event, the award may have no readily determinable fair market value.

Records checklist

Bring the following to an equity compensation consultation:

• Plan document and summary plan description
• Award agreement and grant notice (option type, strike price, vesting schedule, expiration)
• Vesting schedule and confirmation of each vest event (dates and share counts)
• Exercise confirmations (dates, shares, strike price, fair market value at exercise)
• Sell-to-cover or share withholding records
• Form W-2 and Form 1099 for each year of vest, exercise, and sale
• Form 3921 and Form 3922 if received
• Broker statements showing cost basis and proceeds for each sale
• Foreign tax records: pay slips, withholding statements, or tax assessments for vest or sale events in each country
• Currency conversion rates or records for each event if compensation or proceeds involved foreign currency
• Section 83(b) election filings, if made
• 409A valuations (for private-company awards)
• Prior U.S. tax returns, particularly if FEIE or FTC was claimed on equity income
• Work-location calendar or travel records for the vesting period, if multicountry sourcing applies

What this guide does not do

This guide does not provide investment advice, securities valuation opinions, employer payroll instructions, foreign employment-law guidance, or a definitive calculation for any specific award. The analysis for your specific instrument, plan terms, work history, and tax years requires a written engagement and review of actual documents.
