General Instructions
Future Developments
For the latest information about developments
related to Form 4137 and its instructions,
such as legislation enacted after they were
published, go to www.irs.gov/Form4137.
What’s New
For 2018, the maximum wages and tips
subject to social security tax increases to
$128,400. The social security tax rate an
employee must pay on tips remains at 6.2%
(0.062).
Reminder
A 0.9% Additional Medicare Tax applies to
Medicare wages, Railroad Retirement Tax Act
compensation, and self-employment income
over a threshold amount based on your filing
status. Use Form 8959, Additional Medicare
Tax, to figure this tax. For more information
on the Additional Medicare Tax, see “What is
the Additional Medicare Tax?” at
www.irs.gov/AdMT.
Purpose of form. Use Form 4137 only to
figure the social security and Medicare tax
owed on tips you didn’t report to your
employer, including any allocated tips shown
on your Form(s) W-2 that you must report as
income. You also must report the income on
Form 1040, line 1; Form 1040NR, line 8; or
Form 1040NR-EZ, line 3. By filing this form,
your social security and Medicare tips will be
credited to your social security record (used
to figure your benefits). Don’t use Form 4137
as a substitute Form W-2.
!
CAUTION
If you believe you’re an employee
and you received Form 1099-
MISC, Miscellaneous Income,
instead of Form W-2, Wage and
Tax Statement, because your
employer didn’t consider you an employee,
don’t use this form to report the social
security and Medicare tax on that income.
Instead, use Form 8919, Uncollected Social
Security and Medicare Tax on Wages.
For Paperwork Reduction Act Notice, see your tax return instructions.

Who must file. You must file Form 4137 if
you received cash and charge tips of $20 or
more in a calendar month and didn’t report all
of those tips to your employer. You also must
file Form 4137 if your Form(s) W-2, box 8,
shows allocated tips that you must report as
income.
Allocated tips. You must report all your tips
from 2018, including both cash tips and
noncash tips, as income on Form 1040, line 1;
Form 1040NR, line 8; or Form 1040NR-EZ,
line 3. Any tips you reported to your employer
in 2018 are included in the wages shown on
your Form W-2, box 1. Add to the amount in
box 1 only the tips you received in 2018 and
didn’t report to your employer. This should
include any allocated tips shown on your
Form(s) W-2, box 8, unless you have
adequate records to show that your
unreported tips are less than the amount in
box 8. Although allocated tips are shown on
your Form W-2, they aren’t included in box 1
on that form and no tax is 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. Your reportable
tips include cash tips received from
customers, charged tips (credit and debit card
charges) distributed to you by your employer,
and tips received from other employees under
any tip-sharing arrangement. You must report
your tips to your employer 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.
For example, because March 10, 2019, is a
Sunday, you must report your tips received in
February 2019 by March 11, 2019.
Employees subject to the Railroad
Retirement Tax Act. Don’t use Form 4137 to
report tips received for work covered by the
Railroad Retirement Tax Act. 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),
Additional Medicare 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 weren’t 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
wasn’t enough money to cover the social
security and Medicare tax (or railroad
retirement tax), your Form W-2 also will show
the uncollected tax due in box 12 with codes
A and B. See the instructions for Schedule 4
(Form 1040), line 62, or Form 1040NR, line 60,
to find out how to report the tax due. If you
worked in American Samoa, Guam, or the
U.S. Virgin Islands, the amount of uncollected
tax due is identified in box 12 on Form
W-2AS, W-2GU, or W-2VI with codes A and
B. If you worked in Puerto Rico, Form 499R-2/
W-2PR, boxes 22 and 23, show the
uncollected tax due. Unlike the uncollected
portion of the regular (1.45%) Medicare tax,
the uncollected Additional Medicare Tax isn’t
reported on Form W-2, box 12, with code B.
Penalty for not reporting tips. If you didn’t
report tips to your employer as required, you
may be charged a penalty equal to 50% of
the social security, Medicare, and Additional
Medicare Taxes due on those tips. You can
avoid this penalty if you can show (in a
statement attached to your return) that your
failure to report tips to your employer was due
to reasonable cause and not due to willful
neglect.
Additional information. See Pub. 531,
Reporting Tip Income. See Rev. Rul. 2012-18
for guidance on taxes imposed on tips, and
the difference between tips and service
charges. You can find Rev. Rul. 2012-18,
2012-26 I.R.B. 1032 at www.irs.gov/
irb/2012-26_IRB#RR-2012-18.
Specific Instructions
Line 1. Complete a separate line for each
employer. If you had more than five
employers in 2018, 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 statements. Include your name,
social security number, and calendar year
(2018) on the top of any attachment.
Column (a). Enter your employer’s name
exactly as shown on your Form W-2.
Column (b). For each employer’s name you
entered in column (a), enter the employer
identification number (EIN) or the words
“Applied For” exactly as shown on your Form
W-2.
Column (c). Include all cash and charge
tips you received. This includes the following
tips.
• Total tips you reported to your employer on
time. 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 2017 that you
reported to your employer after December 31,
2017, but by January 10, 2018, are
considered income in 2018 and should be
included on your 2018 Form W-2 and
reported on Form 4137, line 1. However, tips
you received in December 2018 that you
reported to your employer after December 31,
2018, but by January 10, 2019, are
considered income in 2019. Don’t include
these tips on line 1.
• Tips you didn’t report to your employer on
time or didn’t report at all (include any
allocated tips shown in box 8 on your Form(s)
W-2 unless you can prove that your
unreported tips are less than the amount in
box 8). These tips are considered income to
you in the month you actually received them.
For example, tips you received in December
2018 that you reported to your employer after
January 10, 2019, are considered income in
2018 because you didn’t report them to your
employer on time.
• Tips you received that you weren’t required
to report to your employer because they
totaled less than $20 during the month.
• Allocated tips you must report as income
(see Allocated tips above).
Line 5. Enter only the tips you weren’t
required to report to your employer because
the total received was less than $20 in a
calendar month. These tips aren’t subject to
social security and Medicare tax.
Line 6. Enter this amount on Form 8959, line
2, if you’re required to file that form.
Line 8. For railroad retirement (RRTA)
compensation, don’t include an amount
greater than $128,400, which is the amount
subject to the 6.2% rate for 2018.
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. Don’t reduce the actual entry on
line 6. Enter “1.45% tips” and the amount you
subtracted on the dotted line next to line 10.
Line 11. Multiply the amount on line 10 by
0.062 (the social security rate for 2018).
Line 13. Form 1040-SS and Form 1040-PR
filers, include the amount from line 13 on
Form 1040-SS or Form 1040-PR, line 6. See
the instructions for Form 1040-SS or Form
1040-PR for more information.
