Publication 571
taxmap/pubs/p571-006.htm#en_us_publink1000239625Generally, you do not report contributions to your 403(b) account
(except Roth contributions) on your tax return. Your employer will report
contributions on your Form W-2. Elective deferrals will be shown in box 12 and
the
Retirement plan
box will be checked in box 13. If you are a self-employed minister or chaplain,
see the discussions next.
taxmap/pubs/p571-006.htm#en_us_publink1000239626If you are a self-employed minister, you must report the total
contributions as a deduction on your tax return. Deduct your contributions on
line 28 of Form 1040.
taxmap/pubs/p571-006.htm#en_us_publink1000239627If you are a chaplain and your employer does not exclude contributions
made to your 403(b) account from your earned income, you may be able to take a
deduction for those contributions on your tax return.
However, if your employer has agreed to exclude the contributions from your
earned income, you will not be allowed a deduction on your tax return.
If you can take a deduction, include your contributions on line
36 of Form 1040. Enter the amount of your deduction and write "403(b)" on the
dotted line next to line 36.
