I am here in US on L1 Visa. My family joined me on 24th Dec 2015 and are planning to return India before end of this Year i.e. 2016.
For the year 2016, I have submitted W-4 claiming deduction for Family. ==========> The IRS recommends that employees consider submitting a W-4 each year or as often as necessary to reflect current personal and financial circumstances .Your employer uses that information to calculate the amount of federal income tax withholding to deduct from your payroll checks.You should periodically adjust their withholding to match their expected income tax liability
My doubt is, can I submit my return for 2016 claiming deduction for family. Though my wife has got SSN, kids don't have TIN#.==>>I assume that you are a US resident for tax purposes, then, on your 2016 return, you can claim your spouse with her SSn and your kids; You must provide more than half of the kids?(whether or not they were in US or INDIA) total support during the calendar year.
you may use the latest revision of Form W-7 to apply and just put "applying ITIN" in depednents' SSN field on your return unles you receive ITINs for your kids before you file 2016 return ; You should complete Form W-7 as soon as you are ready to file your federal income tax return, since you need to attach the return to your application.
