Publication 505
taxmap/pubs/p505-003.htm#en_us_publink10007272The value of certain noncash fringe benefits you receive from
your employer is considered part of your pay. Your employer generally must
withhold income tax on these benefits from your regular pay.
Although the value of your personal use of an employer-provided car, truck, or
other highway motor vehicle is taxable, your employer can choose not to withhold
income tax on that amount. Your employer must notify you if this choice is made.
taxmap/pubs/p505-003.htm#en_us_publink10007273Your employer can choose to treat a fringe benefit as paid by
the pay period, by the quarter, or on some other basis as long as the benefit is
considered paid at least once a year. Your employer can treat the benefit as
being paid on one or more dates during the year, even if you get the entire
benefit at one time.
taxmap/pubs/p505-003.htm#en_us_publink10007274Your employer can choose to treat a benefit provided during November
or December as paid in the next year. Your employer must notify you if this rule
is used.
taxmap/pubs/p505-003.htm#en_us_publink10007275Your employer considers the value of benefits paid from November
1, 2009, through October 31, 2010, as paid to you in 2010. To determine the
total value of benefits paid to you in 2011, your employer will add the value of
any benefits paid in November and December of 2010 to the value of any benefits
paid in January through October of 2011.
taxmap/pubs/p505-003.htm#en_us_publink10007276Your employer cannot choose when to withhold tax on the transfer
of either real property or personal property of a kind normally held for
investment (such as stock). Your employer must withhold tax on these benefits at
the time of the transfer.
taxmap/pubs/p505-003.htm#en_us_publink10007277Your employer can either add the value of a fringe benefit to
your regular pay and figure income tax withholding on the total or withhold a
flat percentage of the benefit's value.
If the benefit's actual value cannot be determined when it is
paid or treated as paid, your employer can use a reasonable estimate. Your
employer must determine the actual value of the benefit by January 31 of the
next year. If the actual value is more than the estimate, your employer must pay
the IRS any additional withholding tax required. Your employer has until April 1
of that next year to recover from you the additional income tax paid to the IRS
for you.
taxmap/pubs/p505-003.htm#en_us_publink10007278Your employer must report on Form W-2 the total of the taxable
fringe benefits paid or treated as paid to you during the year and the tax
withheld for the benefits. These amounts can be shown either on the Form W-2 for
your regular pay or on a separate Form W-2. If your employer provided you with a
car, truck, or other motor vehicle and chose to treat all of your use of it as
personal, its value must be either separately shown on Form W-2 or reported to
you on a separate statement.
