any taxable and nontaxable amounts.
Box 11. This amount is (a) reported in box 1 if it is a distribution made to you
from a nonqualified deferred compensation or nongovernmental section
457(b) plan, or (b) included in box 3 and/or 5 if it is a prior year deferral under
a nonqualified or section 457(b) plan that became taxable for social security
and Medicare taxes this year because there is no longer a substantial risk of
forfeiture of your right to the deferred amount. This box shouldn’t be used if
you had a deferral and a distribution in the same calendar year. If you made a
deferral and received a distribution in the same calendar year, and you are or
will be age 62 by the end of the calendar year, your employer should file
Form SSA-131, Employer Report of Special Wage Payments, with the Social

Box 12. The following list explains the codes shown in box 12. You may
need this information to complete your tax return. Elective deferrals (codes
D, E, F, and S) and designated Roth contributions (codes AA, BB, and EE)
under all plans are generally limited to a total of $18,500 ($12,500 if you only
have SIMPLE plans; $21,500 for section 403(b) plans if you qualify for the
15-year rule explained in Pub. 571). Deferrals under code G are limited to
$18,500. Deferrals under code H are limited to $7,000.
However, if you were at least age 50 in 2018, your employer may have
allowed an additional deferral of up to $6,000 ($3,000 for section 401(k)(11)
and 408(p) SIMPLE plans). This additional deferral amount is not subject to
the overall limit on elective deferrals. For code G, the limit on elective
deferrals may be higher for the last 3 years before you reach retirement age.
Contact your plan administrator for more information. Amounts in excess of
the overall elective deferral limit must be included in income. See the
instructions for Form 1040.
Note: If a year follows code D through H, S, Y, AA, BB, or EE, you made a
make-up pension contribution for a prior year(s) when you were in military
service. To figure whether you made excess deferrals, consider these
amounts for the year shown, not the current year. If no year is shown, the
contributions are for the current year.
