Yes, if relatives are joining. Each joining spouse and each unmarried child under 21 must be considered in the initial application and carries an additional US$15,000 processing fee plus an additional US$1 million gift. A family of four therefore involves four sets of amounts. Calculate the total against net proceeds, not the headline sale price.
Decide the household composition before filing
Because joining relatives must be considered in the initial application, the family list is an early decision rather than a later addition. Write down who intends to move, each person's relationship and age, and whether anyone plans to follow afterwards. Then compare the arithmetic with the funds actually available after taxes and costs.
If the proceeds cover fewer people than intended, discuss that with counsel before the application is started rather than after fees are paid. Add one further check to that arithmetic: what happens if the household changes while the plan is being executed. A marriage, a birth, a child reaching an age threshold, or a separation each alters who may be included, and a calculation built around a fixed list will not answer the question when it arises.
Raise every borderline case with a qualified adviser at the point the list is drawn rather than when a payment schedule already depends on it. Hypothetical example: a household includes a twenty-year-old whose circumstances are likely to change within the year, and the question of what that would mean, and by when, belongs in the first conversation rather than in the tenth month when the position has hardened.
