State Tax After Moving: Installments, Earnouts and Business Sales

The wire date is not always the tax date that matters.

The governing question is:

What created the right to the money?

Moving before payment is not the same as moving before the transaction

A taxpayer who sells stock before moving and later receives an installment payment can face a different state result from someone who moves first and sells passive stock afterward.

California's installment example

California guidance addresses a former resident who sold stock on installment while still resident and then moved to Florida.

The later gain component remains California taxable because the taxpayer was a resident when the stock was sold, while the later interest component is treated separately.

The precise rule is not “California taxes every installment after you leave.” The original transaction matters.

Connecticut can accelerate the issue at departure

Connecticut special-accrual rules can include deferred gain on installment obligations when the right to receive the income is fixed and the amount reasonably determinable.

New York can continue sourcing former-business income

New York rules can reach certain income connected with a business, trade, profession or occupation previously carried on in New York, including specified covenant and termination payments.

Earnouts need character before source

An earnout can represent additional purchase price, compensation, covenant payments, business income, disposition proceeds, or a combination.

The purchase agreement and employment terms matter.

The PRISM principle

Do not source the bank deposit.

Source the transaction that created it.
