Wis. Admin. Code § Tax 3.10
(2) Definitions. In this section and in ss. 71.05 (1) (i) and 71.26 (1) (i), Stats.:
(b) “Business purpose” means activities undertaken for an industrial, commercial, or professional purpose. “Business purpose” does not include any of the following:
5. Activities conducted by nonprofit organizations, unless one of the following apply:
(e) “Financial institution” means a financial institution, as defined in s. 69.30 (1) (b), Stats., that is authorized to do business under state or federal laws relating to financial institutions and is one of the following:
(j) “Residing in this state” means any of the following, determined for the person’s taxable year in which the loan origination occurs:
(4) Proceeds used in this state. In order for a commercial loan to qualify for the exemption in ss. 71.05 (1) (i) and 71.26 (1) (i), Stats., the loan proceeds must be used primarily for a business or agricultural purpose in this state.
Example: Financial Institution A issues a loan to Business B for $4,000,000. Business B uses $3,000,000 of the loan proceeds to expand their manufacturing facility in Wisconsin and $1,000,000 to renovate their headquarters office in Illinois. The loan is used primarily for a business purpose in Wisconsin since 75% of the loan proceeds ($3,000,000 / $4,000,000) were used to expand the Wisconsin facility.
(5) Commercial loan limitation. In order for a commercial loan to qualify for the exemption in ss. 71.05 (1) (i) and 71.26 (1) (i), Stats., the commercial loan must be $5,000,000 or less. All of the following apply to the $5,000,000 limitation:
(a) General.
3. Charge-offs or amounts not expected to be recoverable from a borrower do not reduce the original loan obligation.
Example 1) A borrower is issued a commercial loan with an obligation of $4,900,000 and incurs costs and fees of $150,000 on that loan. The borrower does not pay the $150,000 up front but instead rolls the amount into the loan. Since the loan obligation and costs and fees equal an original loan obligation of $5,050,000, income from the loan does not qualify for the exemption.
Example 2) A bank lends a borrower $6,000,000 on an original commercial loan but charges off $2,000,000 and keeps track of the charged-off balance. Since the original borrowed obligation is $6,000,000, income from the loan does not qualify for the exemption.
(c) Loan participation and assignment. A commercial loan with an original loan obligation over $5,000,000 to a single borrower does not qualify for the exemption, regardless of whether the loan is sold or assigned, in whole or in part, to another financial institution for $5,000,000 or less. A financial institution that acquires a commercial loan through a purchase, assignment, or participation agreement may not exempt the income derived from the acquired loan if the original loan obligation is more than $5,000,000.
Example 1) Bank A issues a commercial loan of $7,000,000. Bank B purchases a loan participation of $3,000,000 in the commercial loan. The income derived from the commercial loan does not qualify for the exemption for Bank A or Bank B because the original loan obligation is over $5,000,000.
Example 2) Assume the same facts as Example 1, except that $3,000,000 of the original loan obligation is assigned by Bank A to Bank B. The income derived from the commercial loan does not qualify for the exemption for Bank A or Bank B because the original loan obligation is over $5,000,000.
Example 3) A commercial loan of $5,000,000 is issued by Bank A. Bank B purchases a loan participation of $3,000,000 in the commercial loan from Bank A. The income derived from the commercial loan may qualify for the exemption for Bank A and Bank B because the original loan obligation was for $5,000,000 or less.
(d) Loan syndication. If one or more financial institutions enter a loan syndication where both financial institutions will be originating the loans, the total loan amount provided to the borrower is used to determine the original loan obligation, not each financial institution’s portion of the syndicated loan. If the original loan obligation is $5,000,000 or less, each financial institution may qualify for the exemption in proportion to the financial institution’s interest in the syndicated loan.
Example: Four financial institutions pool their resources to fund a loan syndication to a borrower for a total original loan obligation of $20,000,000. Although each financial institution funds $5,000,000 of the loan, income derived from the $20,000,000 loan does not qualify for the exemption.
(e) Aggregating multiple commercial loans. All of the following apply to aggregating multiple commercial loans:
3. A commercial loan over $5,000,000 does not qualify, regardless of whether a portion of the loan is used for purposes outside this state.
Example: A commercial loan is issued for $15,000,000 and 33% or $4,950,000 of the proceeds are used for a business purpose in Wisconsin and 67% outside Wisconsin. The income derived from the commercial loan does not qualify for the exemption because the original loan obligation is over $5,000,000.
(6) Record keeping.
(a) A financial institution shall keep electronic records in easily accessible and usable form to substantiate the exemption from income for each loan, including electronic data that can be queried and analyzed for each of the following data elements:
