Estate & Legacy Planning

What Happens When a Trust Beneficiary Moves to the United States?

John’s estate plan was designed to divide his wealth equally among three children who were living in Canada at the time. 

However, when one son permanently moved to the United States, the estate plan wasn’t updated. What had previously been an “equal” inheritance was suddenly disrupted by cross-border tax implications that reduced one beneficiary’s inheritance.

Case Study: When a Family Trust Faces Cross-Border Complexities

Summary of Key Points

  • John created a family trust while every beneficiary lived in Canada.
  • One beneficiary later became a permanent US resident.
  • The trust distributions created Canadian and US tax obligations for the beneficiary who lived in the United States.
  • Equal distributions didn’t produce equal results.
  • The unresolved complexity contributed to family tension.
  • This situation could have been avoided if the estate plan had been reviewed each year and a tax strategy had been developed. 

How a Family Trust Failed to Provide Equal Outcomes

John created a family trust in Canada as part of his estate plan, naming his three children as beneficiaries.

At the time, all three children lived in Canada, and the trust structure worked well. It was aligned with his goals. The plan was straightforward: preserve wealth and divide it equally among his children.

Several years later, one of his sons, Bobby, moved to the United States for university. He eventually married, started a family, and decided to remain in the US permanently.

Unfortunately, the trust was not reviewed after Bobby became a US resident.

When income was distributed to Bobby, Canadian withholding tax applied because he was a non-resident. At the same time, he was required to report that income on his US tax return. This created additional reporting obligations and potential double taxation issues.

No changes were made to address the cross-border implications of the trust. 

When John passed away, the trust distributed capital equally to all three children. What seemed simple on paper became complicated in practice. Two children were Canadian residents. One was a U.S. resident.

The family struggled with difficult questions:

  • Should the estate be divided equally before tax or after tax?
  • How should currency differences and tax burdens be handled?
  • Was Bobby effectively receiving less because of cross-border tax costs?

The children wanted to honour their father’s wish for fairness. 

But without prior planning, the financial and tax complexity created tension during an already emotional time.

In this case, it would have been helpful if John had received advice from a tax professional who understood cross-border trusts. It’s truly unfortunate when adult kids have to deal with the grief of losing a parent while also trying to sort out cross-border trust complexities. 

This story illustrates how important every aspect of planning is when creating a trust.

Whether or not you have beneficiaries in the US, you should look at every aspect of the trust and its tax implications. You should also review your estate planning each year so that everything stays up to date.

Why This Matters

Families rarely remain at a stand still. 

Children move, marry, build careers abroad, and become subject to different tax systems. They may get divorced, remarry, and have kids. Their kids may have grandchildren. If any one of your beneficiaries moves across the border or to another country, their inheritance may be affected. 

John’s story shows why estate planning must be treated as an ongoing process. 

Regular reviews can identify new cross-border issues before they affect distributions, family relationships, or the intended fairness of an inheritance.
