Yes, if you are otherwise qualified to claim the children as dependents, then you may claim them on your tax return. If are ever unsure, you can go thru the steps at the IRS webpage Who is my
dependent?.
You should consider all the things SweetieJean mentioned as well as being aware of all the credits that are reduced or lost when you file Married Filing Separately instead of Married Filing Jointly.
The following come from Tax
Products IRS Tax Map 2015
If you choose married filing separately
as your filing status, the following special rules apply. Because of
these special rules, you usually pay more tax on a separate return than
if you use another filing status you qualify
for.
-
Your tax rate generally is higher than on a joint return.
-
Your exemption amount for figuring the alternative minimum tax is half that allowed on a joint
return.
-
You cannot
take the credit for child and dependent care expenses in most cases, and
the amount you can exclude from income under an employer's dependent
care assistance program is limited to $2,500 (instead of $5,000).
However, if you are legally separated or living apart from your spouse,
you may be able to file a separate return and still take the credit. For
more information about these expenses, the credit, and the exclusion,
see Pub 17, chapter 32.
-
You cannot take the earned income credit.
-
You cannot take the exclusion or credit for adoption expenses in most cases.
-
You cannot
take the education credits (the American opportunity credit and lifetime
learning credit) or the deduction for student loan
interest.
-
You cannot exclude any interest income from qualified U.S. savings bonds you used for higher education expenses.
-
If you lived with your spouse at any time during the tax year:
-
You cannot claim the credit for the elderly or the disabled,
and
-
You must
include in income a greater percentage (up to 85%) of any social
security or equivalent railroad retirement benefits you
received.
-
The following credits and deductions are reduced at income levels half those for a joint
return:
-
The child tax credit,
-
The retirement savings contributions credit,
-
The deduction for personal exemptions, and
-
Itemized deductions.
-
Your capital loss deduction limit is $1,500 (instead of $3,000 on a joint return).
-
If your
spouse itemizes deductions, you cannot claim the standard deduction. If
you can claim the standard deduction, your basic standard deduction is
half the amount allowed on a joint
return.
For those who may still feel they need to file separately because they or their spouse owes a debt that results in the IRS offsetting (keeping) their tax refund to pay the bill, review the Injured Spouse information here -> IRS
Injured Spouse Info and here -> Injured
