Nearly 85,000 American citizens live in Hong Kong (U.S. Department of State). While you benefit from local salaries tax capped at 17%, you still need to file a U.S. federal return and a Hong Kong tax return each year. When it comes to Hong Kong tax compliance for americans, understanding both systems keeps you on track, helps you claim credits, and avoids steep penalties. Key takeaway, you must juggle U.S. forms and territory-based filings to stay compliant and optimize your tax position.
Understand dual filing duties
As a U.S. citizen, the IRS taxes your worldwide income. At the same time, Hong Kong applies a territorial system, taxing only income sourced within its borders. No tax treaty exists between the U.S. and Hong Kong, so you can’t defer U.S. taxes on Hong Kong earnings (see Hong Kong tax treaties with the U.S. for more). Good news, you can often offset local taxes against your U.S. bill.

Explore Hong Kong tax system
Hong Kong’s tax year runs April 1 to March 31. The Inland Revenue Department issues returns—usually in May—and you must file within one month of issue. There’s no withholding, so you calculate and pay directly.
| Tax type | Rate or basis | Key point |
|---|---|---|
| Salaries Tax | Progressive 2%–17% | On Hong Kong–sourced salaries |
| Profits Tax | 8.25% on first HK$2 million, then 16.5% | On trade or business profits |
| Property Tax | 15% on net assessable rental | After 20% statutory deduction |
Benefit from the 60-day rule
If you work in Hong Kong fewer than 60 days in a tax year, you’re generally exempt from salaries tax (foreigners only). That can save you up to 17% on short-term assignments. See Hong Kong tax residency rules for U.S. expats for details.
Track residency and domicile
Your tax status depends on days spent and intent to stay. A longer stay or declared domicile triggers full liability. Learn more in our guide to Hong Kong tax residency and domicile rules.
Meet US reporting duties
Your Hong Kong accounts and investments often trigger extra IRS forms. Missing deadlines can cost you dearly—penalties for failing to file an FBAR can reach $10,000 per violation (IRS).
Report foreign bank accounts
If your combined non-U.S. financial accounts exceed $10,000 at any point, file FinCEN Form 114 (FBAR).
- Deadline: April 15 with automatic extension to October 15
- Penalty: Up to $10,000 per non-willful violation
Declare specified assets
Form 8938 (FATCA) covers foreign stocks, bonds, mutual funds, ETFs, pensions, and more, if totals exceed:
- $200,000 on December 31 or $300,000 at any time (single filers)
- $400,000 on December 31 or $600,000 at any time (married filing jointly)
A 2023 IRS report found 35% of expats missed Form 8938 deadlines, risking penalties up to $10,000 plus 5% of asset value.
Claim foreign tax credits
You can offset Hong Kong tax paid against your U.S. liability using Form 1116. That reduces double taxation on salaries and business profits. For help, see U.S. expat tax credits in Hong Kong.
Disclose foreign trusts
If you own or receive distributions from a foreign trust, file Forms 3520 and 3520-A. These filings are complex, so plan ahead or work with a specialist.
Apply planning best practices
A little foresight can trim your bills and ease compliance stress.
Use available deductions
Explore Hong Kong reliefs and allowances—such as dependent deductions and charitable contributions. See Hong Kong specific tax deductions for expats.
Coordinate deadlines
Align your U.S. and Hong Kong filings to avoid surprises. Hong Kong returns are due one month after issue (usually June), while U.S. returns go out by mid-April (extended to October). Learn more at Hong Kong tax return deadlines for expats.

Frequently asked questions
Do I need to file a U.S. return if I live in Hong Kong?
Yes, as a U.S. citizen you file Form 1040 regardless of residence. You’ll report worldwide income and can use credits or exclusions to lower your U.S. tax.
Can I avoid double taxation on my Hong Kong salary?
Generally yes. You can use the Foreign Earned Income Exclusion (up to $120,000 in 2024) or claim a foreign tax credit on Form 1116 to offset Hong Kong tax paid.
What happens if I miss a Hong Kong filing deadline?
Late filing can incur penalties and interest. You can request an extension from the Inland Revenue Department, but it’s best to file on time to avoid assessments. See Hong Kong tax filing requirements for U.S. expats for guidance.
