Box 6. For a taxable covered security, shows the amount of acquisition
premium amortization for the year that reduces the amount of OID that is
included as interest on your income tax return . If an amount is reported in this
box, see the Instructions for Schedule B (Form 1040 or 1040-SR). If an amount
is not reported in this box for a covered security acquired with acquisition
premium, the payer has reported a net amount of OID that reflects the offset of
OID that is included in income. If the payer has reported a net amount of OID in
box 1 or box 8, you must report the net amount of OID on Schedule B (Form
1040 or 1040-SR) and you must not make an adjustment to this amount for
acquisition premium on Schedule B (Form 1040 or 1040-SR).
If there is an amount in both boxes 6 and 11, for a tax-exempt obligation that
is a covered security acquired on or after January 1, 2017, and is issued with
OID, the amount in box 6 shows the amount of acquisition premium
amortization for the year that reduces the amount of your tax-exempt OID for
the year. The payer may, but is not required to, report the acquisition premium
for a tax-exempt obligation that is a covered security acquired before January 1,
2017, and issued with OID. See the instructions above for a covered security
acquired with acquisition premium
Box 11. For a tax-exempt obligation that is a covered security acquired on or
after January 1, 2017, shows the tax-exempt OID on the obligation for the part
of the year you owned it. The payer may, but is not required to, report the OID
for a tax-exempt obligation that is a covered security acquired before January 1,
2017. In general, report the amount of tax-exempt OID on Form 1040 or
1040-SR. See the instructions above for a covered security acquired with
acquisition premium.
If appropriate, I have entered a 2nd line with a negative number for these income lines to clearly show the adjustment.
