What are the tax implications if a seller changes their state of residency or moves internationally during an active Section 453 installment sale?

Question

Tyler Smith · Accepted Answer

Changing your residency while an active **Section 453 installment sale** is in progress can introduce significant tax complexities, particularly concerning state and international tax obligations.

## State Tax Implications

When a seller moves across state lines, the original state of residency may still claim the right to tax the income from the installment note payments. This is primarily based on the **source** of the income, which refers to where the property initiating the sale was located.

Key considerations for state taxes include:

*   **Source of Income Rules**: Many states consider the income from the installment sale to be sourced to the state where the property was located at the time of sale, regardless of the seller's current residency.
*   **Recapture Provisions**: Some states have specific provisions that allow them to continue taxing income from sources within their borders, even for non-residents.
*   **New State Taxation**: The new state of residency may also attempt to tax the installment income as it is received. This can lead to **double taxation** if not properly managed.
*   **Tax Credits**: To mitigate double taxation, sellers may need to utilize tax credits for taxes paid to other states.

## International Tax Implications

Moving internationally while holding an **installment note** introduces even greater challenges.

*   **Worldwide Income Taxation**: U.S. citizens and permanent residents are generally subject to taxation on their **worldwide income**, regardless of their place of residence. Therefore, installment payments remain taxable by the U.S.
*   **Foreign Country Taxation**: The new country of residence may also impose income tax on the installment payments received by its residents.
*   **Tax Treaties**: To avoid or reduce double taxation, sellers must navigate complex tax treaties between the U.S. and their new country of residence. These treaties often dictate which country has the primary right to tax certain types of income.
*   **Expatriation Taxes**: If a U.S. citizen renounces their citizenship or a long-term resident abandons their green card, they may be subject to **expatriation taxes**. This could trigger an acceleration of gain recognition on the outstanding installment note.
