You must enter your taxpayer identification number (generally your
social security or employer identification number) on all returns,
statements, or documents you must file. For example, you must enter it
on your federal income tax return, your estimated tax payment voucher,
and all information returns, such as Forms 1096 and 1099. You may be
subject to a penalty of $50 for each failure to enter the number.
Schedule F.
Enter your social security number (SSN) in the space provided on
the first line of Schedule F. You need an employer identification
number (EIN) if you have a Keogh plan or must file an employment,
excise, estate, trust, partnership, or alcohol, tobacco, and firearms
tax return. Enter that EIN on line D of Schedule F.
Other forms and schedules.
On your individual income tax return (Form 1040), schedule of
self-employment tax (Schedule SE), and estimated tax payment voucher
(Form 1040-ES), you should enter your SSN, regardless of which
number you entered on your business returns.
If you are married, enter the SSNs for you and your spouse on your
Form 1040, whether you file jointly or separately. If you are filing a
joint return, list the SSNs in the same order as the names are shown
on your label. Also enter both SSNs on your Form 1040-ES if you
make joint estimated tax payments. Enter them in the same order as
they appear on the joint return.
Applying for a social security number.
To apply for a social
security number (SSN), use Form SS-5. You can get the form from
any social security office or by calling
1-800-772-1213. If you are under 18 years
of age, you must furnish evidence of age, identity, and U.S.
citizenship (or lawful alien status) with your Form SS-5. If you
are 18 or older, you must appear in person with this evidence at a
social security office. It usually takes about 2 weeks to get an SSN.
Applying for an employer identification number.
To apply for an
employer identification number, use Form SS-4. See chapter 21
for information about ordering this form.
