법이 바뀌어서 이번에 아래에 해당하고 16년도 세금리턴 신고할 예정인 사람은 10월1일부터 ITIN을 renew 해야한다는데요.

• Unused ITINs. ITINs not used on a federal income tax return in the last three years (covering 2013, 2014, or 2015) will no longer be valid to use on a tax return as of Jan. 1, 2017. ITIN holders in this group who need to file a tax return next year will need to renew their ITINs. The renewal period begins Oct. 1, 2016.
• Expiring ITINs. ITINs issued before 2013 will begin expiring this year, and taxpayers will need to renew them on a rolling basis. The first ITINs that will expire under this schedule are those with middle digits of 78 and 79 (Example: 9XX-78-XXXX). The renewal period for these ITINs begins Oct. 1, 2016. The IRS will mail letters to this group of taxpayers starting in August to inform them of the need to renew their ITINs if they need to file a tax return and explain steps they need to take. The schedule for expiration and renewal of ITINs that do not have middle digits of 78 and 79 will be announced at a future date.
