True, but the original post did not ask about this.
I'm confused. Suppose the original poster is a CA resident. Suppose
the CA marginal tax rate is 10% and AZ is 2.5%. Suppose the profit is
10k. There are 2 ways.
(1) Since this is AZ real property, AZ gets 2.5% of 10k or $250. In
fact, they might impose witholding on the sale of the property -- at
least CA does this for nonresidents. CA taxes 10% of 10k or $1000
minus the credit paid to AZ, so net to CA is $750.
(2) Since the person is a CA resident, CA first gets their $1000. AZ
tax is $250 but minus the $1000 paid to CA, the net AZ tax is $0.
In both cases the person pays $1000, but each method pays to different
states. I'm sure the states have a rule they follow. From what you
wrote above it seems like you're saying it is method (2). Where is
this in the rules?

A little further explanation:
In general, states tax their residents on all income, regardless of
its source. States also tax nonresidents on income from sources
within the state. As a result, if you are a resident of State A and
have income from a source in State B, both State A and State B will
tax that income. (Of course there are exceptions; some states have no
individual income taxes, and a few states exempt a resident's business
income from out-of-state sources.)
The resulting double taxation may be mitigated by a credit granted by
one state for the tax paid to the other, or by a reciprocal agreement
between two states. Reciprocal agreements generally apply only to
income from employment (wages), so that a resident of one state
working in the other pays tax on his or her earnings only to the state
of residence. Thus the source state cedes the tax to the residence
state. California has no reciprocal agreement with any other state.
Credits for taxes paid to other states generally are allowed to
residents of the state granting the credit. As a rule the credit is
limited to the lesser of (a) the tax actually paid to the source state
or (b) the proportion of the resident state tax liability that relates
to the "double taxed" income. As a result the taxpayer's total net
state income tax on that income is at the higher of the two states'
average rates for that taxpayer's filing status, income level, number
of dependents, etc. When the residence state grants the credit it is
in effect cediing the tax to the source state -- the source state
keeps the money.
A few states stand in a reverse credit relationship whereby the source
state grants a credit for the tax paid to the state of residence.
Arizona, Indiana, Virginia, Oregon, and California have such a reverse
credit relationship with one another. Thus a resident of one of those
states with income sourced in another of them looks to the source
state for a credit for the tax paid to the residence state. In this
case the source state is ceding the tax to the residence state.
Again, the credit is limited to the lesser of (a) the actual tax
liability to the source state or (b) the proportion of the residence
state tax liability that relates to that income, and the net state tax
on the "double taxed" income is at the higher of the two states'
average rates applicable to that taxpayer.
The OP in this thread must pay California tax on the gain on the sale
of his Arizona property, and file an amended return with Arizona to
claim credit for the California tax (assuming the statute of
limitations on the AZ return is still open).
Note that the credit and reciprocal agreement mechanisms that mitigate
(but do not always eliminate) the double taxation of income appear to
be a matter of legislative grace. They are not required by any
constitutional or federal statutory provision. Sometimes credits are
not allowed. For example, many states allow credit for tax paid to
another state only if the tax was paid in the same year; if an item of
income was taxed in one year by State A and in a different year by
State B, no credit may be allowed. Also, many states limit the credit
to taxes paid to the other state on income FROM SOURCES WITHIN THAT
STATE -- and states differ in their definitions of source income. For
example, if you are a California resident and sell real property in
Massachusetts on an installment basis, Massachusetts will tax both the
gain element and the interest income that you receive on the
installment note, because both are considered Massachusetts source
income. California will give you credit for the tax you pay to
Massachusetts on the gain element, because that is Massachusetts
source income by California's lights; but California will not allow
credit for the tax paid to Massachusetts on the interest, because by
California's lights that is income from an intangible (the note) and
is sourced at your residence -- California.
