Why Many People Should “Sell” Everything Before Moving to the United States
One of the most expensive tax mistakes people make when moving to the United States happens before they even arrive.
If you become a U.S. tax resident while holding highly appreciated assets, the United States may later tax you on gains that built up long before you ever lived here. Many people assume U.S. tax only applies going forward. That is often not true.
With proper timing, some people can effectively reset the value of their assets before U.S. residency begins. Missing that window can mean paying capital gains tax on decades of appreciation.
What does “basis” mean in simple terms?
Your tax basis is generally what you paid for an asset.
When you sell an asset, capital gains tax is usually calculated as:
- Sale price minus
- Your basis
If your basis is very low and the asset has grown significantly in value, the taxable gain can be large.
Why moving to the U.S. creates a hidden tax risk
The U.S. taxes residents on worldwide income.
Once you become a U.S. tax resident, this generally includes:
- Foreign stocks and investments
- Business interests
- Real estate outside the U.S.
- Funds and portfolios held abroad
If you later sell those assets, the U.S. may tax the entire gain from your original purchase price, even if most of the growth occurred before you moved.
The core idea behind the “basis step up” strategy.
In many cases, if you sell an asset before becoming a U.S. tax resident, the U.S. is not involved in that transaction.
If you then repurchase the asset before U.S. residency begins:
- The new purchase price becomes your new basis
- Future U.S. tax may apply only to gains after that point.
In simple terms, you are resetting the clock before entering the U.S. tax system.
Why do people say “sell everything” even if you do not really want to
This strategy is often described casually as selling everything, but it does not always mean permanently giving up assets.
In some cases:
- Assets are sold and immediately repurchased
- Holdings are restructured before the move.
- Gains are recognized under foreign tax rules instead of U.S. rules
.
The goal is not to exit investments, but to reset values before U.S. tax residency begins.
Assets where this strategy is commonly considered
This approach is often reviewed for:
- Publicly traded securities
- Investment portfolios
- Closely held business interests
- Certain foreign funds or partnerships
Each asset type has its own complications, and not all assets are suitable.
Common mistakes people make
People often miss this opportunity because they:
- Assume U.S. tax starts only after arrival
- Focus on visas or green cards instead of tax residency.
- Do not realize residency can begin mid-year
- Discover the issue only when they later sell an asset.
By then, the window will have closed.
Important limitations and warnings
This strategy is not automatic and not risk-free.
Important points to understand:
- Foreign taxes may apply to the pre-move sale
- Some countries have exit taxes or anti-avoidance rules.
- Transaction costs and market risk must be considered.
- Wash sale or similar rules may apply, depending on jurisdiction.
- Timing is critical and fact-specific
What works for one person may not work for another.
Simple pre-move checklist
Before becoming a U.S. tax resident, consider asking:
- Do I own assets with large unrealized gains?
- When will my U.S. tax residency begin?
- Would selling before that date reset my basis?
- What taxes apply in my current country if I sell?
- Can assets be repurchased without losing economic position?
These questions are best addressed before the move, not after.
Why this matters for long-term planning
Failing to plan before U.S. residency can result in:
- Higher capital gains taxes years later
- Complicated reporting obligations
- Reduced flexibility in future asset sales
In contrast, thoughtful pre immigration planning can significantly reduce long term tax exposure.

The “Basis Step Up” Strategy: A Costly Tax Mistake Many New U.S. Residents Make
When you move to the U.S., the IRS may tax you on gains that were built up long before you arrived.
In some cases, selling and repurchasing assets before U.S. tax residency begins can reset values and limit future capital gains tax. Miss that window, and the opportunity may be gone forever.
Pre-move tax planning matters more than most people realize.
