What is Form W9 and backup withholding?
|
Your investment income is generally not subject to regular
tax withholding, however, it
may be subject to backup withholding to ensure that income tax is collected on this taxable income. Backup withholding can be taken
by the IRS from your investment income if:
 | you fail to furnish your taxpayer identification number
on Form
W9, Request for
Taxpayer Identification Number and Certification, to payers of interest or
dividend income; |
 | you give them the wrong number; or |
 | you ignore notices from the IRS claiming that you have
under reported interest or
dividend income on your tax return. |
Under backup withholding, when you open up a new account you must certify under
penalties of perjury that your social security number is correct and that you are not
subject to backup withholding on Form
W9, Request for
Taxpayer Identification Number and Certification.
The backup withholding tax rate is
28%.
Additionally, if you don't give the payer your taxpayer identification number the
following can be subject to backup withholding:
 | money you earn as an independent contractor if your fees are $600 or more; |
 | payments from brokers; |
 | royalty payments; and |
 | gambling winnings. |
Form
W9, Request for
Taxpayer Identification Number and Certification, is used to certify under penalties
of perjury that your social security number is correct and that you are not subject to
backup withholding. If you fail to make this certification on a Form W-9, or similar
statement, backup withholding may begin immediately on your new account, and
28% of the
interest or payments paid on your account will be withheld for income tax.
There are both civil and criminal penalties if you provide false information to avoid
backup withholding.
