US green‑card holders face essentially the same tax rules as US citizens. Even if you live abroad, the IRS taxes your worldwide income, unless a qualifying tax‑treaty exemption applies.
Tax obligations for permanent residents
- Worldwide income – You must file a U.S. tax return (Form 1040) and report all income, regardless of where it is earned.
- Treaty relief – If you reside in a country that has an income‑tax treaty with the United States, you may be able to claim treaty benefits (e.g., reduced withholding, exemption of certain income). This requires filing the appropriate treaty‑based forms (e.g., Form 8833) with the IRS.
- Limited treaty network – The U.S. treaty portfolio is narrower than that of many other nations, so treaty relief is not guaranteed.
The “8‑year rule” and exit tax
If you have been a green‑card holder for 8 of the last 15 years, you may be classified as a covered expatriate when you voluntarily surrender the card. The criteria are:
| Criterion | Threshold (adjusted for inflation) |
|---|---|
| Net worth | $2 million (fair‑market value of worldwide assets) |
| Average annual U.S. tax liability (last 5 years) | ≈ $170 000 (inflation‑adjusted) |
Meeting either threshold triggers an exit tax:
- The IRS treats all of your assets as if they were sold on the day you give up the green card.
- You owe tax on the unrealized gains, similar to the “mark‑to‑market” regime applied to U.S. citizens who renounce citizenship.
- The process mirrors the standard expatriation filing (Form 8854) but the underlying liability can be substantial, especially for high‑value portfolios.
Practical considerations
- Assess treaty options early – If you plan to relocate, compare the tax treaty landscape of potential host countries. A favorable treaty can reduce or eliminate U.S. tax on certain income streams (e.g., pensions, dividends).
- Track residency duration – Keep a clear record of the years you hold a green card. Approaching the 8‑year threshold may warrant a review of your long‑term tax exposure.
- Evaluate net‑worth and tax‑liability thresholds – Calculate your worldwide asset base and recent U.S. tax bills. If you are near or above the $2 million or $170 000 marks, an exit tax is likely.
- Timing of relinquishment –
- Before the 8‑year mark: surrendering the green card may avoid the exit tax, but you will still be subject to regular U.S. filing requirements while you remain a resident.
- After the 8‑year mark: you will face the exit tax regardless of when you give up the card, so consider whether obtaining U.S. citizenship (which carries the same tax consequences) might be more advantageous than remaining a permanent resident with no additional benefits.
- Dual‑citizenship implications – If relinquishing the green card requires giving up another citizenship, weigh the personal and legal costs of that loss against any tax advantage.
Bottom line
- Green‑card holders are taxed like U.S. citizens on worldwide income; treaty relief is limited and must be claimed formally.
- Holding a green card for 8 of the past 15 years can trigger an exit tax if your net worth exceeds $2 million or your average U.S. tax liability exceeds roughly $170 000.
- Strategic planning—including early assessment of treaty benefits, careful tracking of residency duration, and proactive calculation of net‑worth thresholds—can help you avoid unexpected tax liabilities when you decide to give up permanent residency.
