如果有一大笔capital loss， federal 反正可以每年抵消3k或者新的capital gain， but 州税， 如果搬去别的州， 是不是这笔carryover就没了.
要看州的 大部分州你capital loss from other states是可以被carry over的 比如你从NY搬到加州
For taxable years beginning on or after January 1, 2002, if you have capital loss carryovers and were a nonresident of California in prior years, the capital loss carryovers need to be restated as if you had been a California resident for all prior years.

Most states treat new residents for tax purposes as if they had always been residents. Thus, if you bought stock for $5K in state A, it was worth $7K when you moved to state B, and you sold it for $10K in state B, your capital gain would be $5K to state B (and state A has no right to tax the $2K.) Similarly, you would be able to carry over any capital loss, if your state allows capital loss carryovers.
And if you pay non-resident tax to a state, you would report a capital loss, which could be either resident or non-resident sourced. Capital losses on stocks are sourced to your state of residence at the time, so you would carry over a NY-sourced capital loss on your NY tax form, and could offset any NY-sourced income. If the original capital loss was realized before you moved to NY, or was sourced to another state (say you sold a rental property in another state for a capital loss), then you would report it on your NY non-resident tax form as a non-NY capital loss, so it would offset your total income (reducing your tax rate) but not your NY source income.
