through December 31, 2025
, a multistate
service provider may elect to treat sales from services as being in this state

sales.� If the election under this subsection is made pursuant to subsection
C

F
of this section, the sales of
services that are in this state shall be determined for taxable years beginning

is made at the time of the original agreement without regard to subsequent
substitutions of collateral.

not secured by real property, the market is in this state if the borrower is
located in this state.

state if the asset is properly assigned to a regular place of business of the
taxpayer in this state. An asset is properly assigned to a regular place
of business in this state if the trading policies or guidelines with respect to
the asset or activity are established in this state. The market for the
