to social security tax is $97,500.
● You are now required to report the employer identification
number and tip information that applies to each employer

based on the information shown on Form 4137.
Purpose of form. Use Form 4137 only to figure the social
security and Medicare tax owed on tips you did not report to
your employer, including any allocated tips shown on your
Form(s) W-2 that you must report as income. You must also

If you believe you are an employee and you
received Form 1099-MISC, Miscellaneous Income,
instead of Form W-2, Wage and Tax Statement,
CAUTION
because your employer did not consider you an
employee, do not use Form 4137. Instead, use Form 8919,
Uncollected Social Security and Medicare Taxes on Wages.
Who must file. You must file Form 4137 if you received cash
and charge tips of $20 or more in a calendar month and did
not report all of those tips to your employer. You must also
file Form 4137 if box 8 of your Form(s) W-2 shows allocated
tips that you must report as income.
Allocated tips. You must report as income on Form 1040,
line 7, or Form 1040NR, line 8, or Form 1040NR-EZ, line 3, at
least the amount of allocated tips shown in box 8 of your
Form(s) W-2 unless you can prove a smaller amount with
adequate records. If you have records that show the actual
amount of tips you received, report that amount even if it is
more or less than the allocated tips. Although allocated tips

are shown on your Form W-2, they are not included in the
wages, tips, and other compensation box (box 1) on that
form and no income tax, social security tax, or Medicare tax
has been withheld from these tips.
Tips you must report to your employer. You must give
your employer a written report of cash and charge tips if you
received $20 or more in tips during a month. If, in any month,
you worked for two or more employers and received tips
while working for each, the $20 rule applies separately to the
tips you received while working for each employer and not to
the total you received. You must report your tips to your
employers by the 10th day of the month following the month
you received them. If the 10th day of the month falls on a
Saturday, Sunday, or legal holiday, give your employer the
report by the next business day.
Employees subject to the Railroad Retirement Tax Act.
Do not use Form 4137 to report tips received for work
covered by the Railroad Retirement Tax Act. In order to get
railroad retirement credit, you must report these tips to your
employer.
Payment of tax. Tips you reported to your employer are
subject to social security and Medicare tax (or railroad
retirement tax) and income tax withholding. Your employer
collects these taxes from wages (excluding tips) or other
funds of yours available to cover them. If your wages were not
enough to cover these taxes, you may have given your
employer the additional amounts needed. Your Form W-2 will
include the tips you reported to your employer and the taxes
withheld. If there was not enough money to cover the social
security and Medicare tax (or railroad retirement tax), your
Form W-2 will also show the tax due in box 12 under codes A
and B. See the instructions for line 63 of Form 1040, or line 58
of Form 1040NR, to find out how to report the tax due. If you
worked in American Samoa, Guam, Puerto Rico, or the U.S.
Virgin Islands, the amount of uncollected tax due should be
identified with codes A and B in box 12 of Form W-2AS,
W-2GU, or W-2 VI; or entered in boxes 22 and 23 of Form
499R-2/W-2PR. See the instructions for line 5 of Form
1040-PR or 1040-SS to find out how to report the tax due.
Penalty for not reporting tips. If you did not report tips to
your employer as required, you may be charged a penalty
equal to 50% of the social security and Medicare tax due on
those tips. You can avoid this penalty if you can show
reasonable cause for not reporting these tips to your
employer. To do so, attach a statement to your return
explaining why you did not report them.
Additional information. See Pub. 531, Reporting Tip
Income.

Specific Instructions
Line 1. Complete a separate line for each employer. If you
had more than 5 employers in 2007, attach a statement that
contains all of the information (and in a similar format) as
required on Form 4137, line 1, or complete and attach line 1
of additional Form(s) 4137. Complete lines 2 through 13 on
only one Form 4137. The line 2 and line 3 amounts on that
Form 4137 should be the combined totals of all your Forms
4137 and attached statement.
Column (a). Enter your employer’s name exactly as it is
entered in box c of your Form W-2.

Column (b). For each employer’s name you entered in
column (a) enter the employer identification number or the
words “applied for” exactly as shown in box b of your Form
W-2.
Column (c). Include all cash and charge tips you received.
This includes the following:
● Total tips you reported to your employer. Tips you
reported, as required, by the 10th day of the month following
the month you received them are considered income in the
month you reported them. For example, tips you received in
December 2006 that you reported to your employer after
December 31, 2006, and before January 11, 2007, are
considered income in 2007 and should be included on your
2007 Form W-2 and reported on line 1 of Form 4137.
However, tips you received in December 2007 that you
reported to your employer after December 31, 2007, and
before January 11, 2008, are considered income in 2008. Do
not include these tips on line 1.
● Tips you did not report to your employer on time or did not
report at all. These tips are considered income to you in the
month you actually received them. For example, tips you
received in December 2007 that you reported to your
employer after January 10, 2008, are considered income in
2007 because you did not report them to your employer on
time.
● Tips you received that you were not required to report to
your employer because they totaled less than $20 during the
month.
● Allocated tips you must report as income (see page 1).
Line 5. Enter only the tips you were not required to report to
your employer because the total received was less than $20
in a calendar month. These tips are not subject to social
security and Medicare tax.
Line 10. If line 6 includes tips you received for work you did
as a federal, state, or local government employee and your
pay was subject only to the 1.45% Medicare tax, subtract
the amount of those tips from the line 6 amount only for the
purpose of comparing lines 6 and 9. Do not reduce the
actual entry on line 6. Enter “1.45% tips” and the amount
you subtracted on the dotted line next to line 10.
