Based on the instruction booklet for OK
individual income tax returns, the filing requirement for OK is determined by
your residency status.
If you are
a resident and you are required to
file a Federal tax return, then you must file an OK tax return.
If you are
a part-year resident, you are under
the same filing requirements as a resident during the period of time that you
were a resident. For the period of time
of non-residency (as a part-year resident), you must file an OK return if your
gross income from OK sources is $1,000 or more.
If you are
a non-resident, you must file an OK
return if your gross income from OK sources is $1,000 or more.
