You should only be paying MO state income taxes on your
MO-source income only. Just make sure that you are doing a MO part-year state
income tax return and only reporting your MO-source income on this MO
part-year resident state income tax return.
MO taxes all the
income reported when calculating MO state income taxes (whether resident,
part-year resident or nonresident) but you will only be required to paid a
portion of the total MO state income taxes calculated (your percentage of the
total MO tax that relates to your MO source income only)
The way that the MO
state income tax return works is that MO looks at all of your income from all
sources and generates a total MO state income tax on all income. When MO
is determining the actual MO state income taxes that you owe, MO multiples
the total MO taxes on all income by the percentage of MO source income over all
source income. So if all your income is $10,000 but MO source income is $8,000,
MO will calculate the MO state income tax on $10,000 then multiply this
total tax by your MO source income over total income ($8,000/$10,000) to get
your percentage of MO state income taxes on your MO source income. So in this
instance, your MO state income tax liability would be 80% of the total amount
of MO taxes generated (on all income). That is why all your income is
being reported on your MO state tax return.
