B1. When do I have to include foreign sourced income in a combined report?

The answer depends on whether the corporation earning the income is a domestic corporation (i.e. incorporated in the U.S.) or a foreign corporation.

Any income excluded from a combined report but which is still taxable under the Internal Revenue Code as modified for Wisconsin purposes must be reported to Wisconsin on a separate entity basis if the corporation has nexus in Wisconsin.

Also, the Department of Revenue has authority to require this income to be included in the combined report in cases where excluding it would result in an avoidance or evasion of tax (sec. 71.255(2)(f), Wis. Stats.).

B2. When do I have to include income of a foreign corporation in a combined report?

It depends on whether the foreign corporation meets the water's edge test described in question A6. If a foreign corporation does not meet the water's edge test (in other words, if 80% or more of its income is active foreign business income), it can be considered to be on the "foreign side of water's edge."

Any income excluded from a combined report but which is still taxable under the Internal Revenue Code as modified for Wisconsin purposes must be reported to Wisconsin on a separate entity basis if the corporation has nexus in Wisconsin.

Also, the Department of Revenue has authority to require this income to be included in the combined report in cases where excluding it would result in an avoidance or evasion of tax (sec. 71.255(2)(f), Wis. Stats.).

B3. How do I know if income is U.S. sourced or foreign sourced?

The combined reporting statute uses sections 861 through 865 of the Internal Revenue Code to distinguish U.S. sourced income from foreign sourced income.

B4. Are intercompany transactions between members of the combined group eliminated for purposes
      of determining the combined group's income?

In general, yes. Since the incomes of the corporations are combined before apportionment, intercompany transactions generally "wash out" in the same manner they would in a federal consolidated return.
