How does an electing tax-option (S) corporation determine the situs of income?
The situs of income for an electing tax-option (S) corporation is determined as if the election under sec.
71.365(4m)(a), Wis. Stats., was not made. Therefore, an electing tax-option (S) corporation must determine income attributable to Wisconsin for each shareholder according to secs.
71.04 and
71.362, Wis. Stats., and use that method for determining the situs of income to the corporation.
Example:
Facts
- Shareholders A and B each own 50 percent of Tax-Option (S) Corporation
- Shareholder A was a Wisconsin resident for the entire year in 2024
- Shareholder B was a nonresident of Wisconsin for the entire year in 2024
- In 2024, 25 percent of Tax-Option (S) Corporation's income is earned in Wisconsin and 75 percent is earned in other states
- Tax-Option (S) Corporation has $100,000 of net ordinary business income for 2024
- Tax-Option (S) Corporation makes an election under sec.
71.365(4m)(a), Wis. Stats., to pay tax at the entity level for 2024
Computation of income attributable to Wisconsin
| | Shareholder A (resident) | Shareholder B (nonresident) |
|---|
| Portion of business income from the tax-option (S) corporation | $50,000 | $50,000 |
|---|
| Wisconsin apportionment % (situs of income) | 100% | 25% |
|---|
| Shareholder's Wisconsin income from the tax-option (S) corporation | $50,000 | $12,500 |
|---|
The electing tax-option (S) corporation's Wisconsin income is $62,500 ($50,000 + $12,500).

Yes. According to sec.
71.365(1)(b), Wis. Stats., the adjusted basis of a shareholder in the stock and indebtedness of a tax-option (S) corporation that has made the entity-level tax election is determined as if the election was not made. According to sec.
71.365(4m)(b), Wis. Stats., it is the intent of the entity-level tax election that the tax-option (S) corporation shall pay tax on items that would otherwise be taxed if this election was not made. Since basis limitations affect the amount of income that would otherwise be taxed on the shareholder's return, such limitations also affect the amount of net income of the tax-option (S) corporation that is subject to tax when the corporation elects to pay tax at the entity level. See Example below.
Facts:
- Tax-Option (S) Corporation AB is 100% owned by Individual Z
- Tax-Option (S) Corporation AB is a calendar-year filer
- Tax-Option (S) Corporation AB makes the entity-level tax election under sec. 71.365(4m)(a), Wis. Stats.

- Beginning stock basis in AB: $5,000
- Ordinary business income from AB: $40,000
- Cash distribution from AB: $50,000
- Section 179 expense from AB: $30,000
- No other items of income, gain, loss, or deduction
At the end of the calendar year, Individual Z has the following:
- $0 of Wisconsin basis in AB
- $5,000 of capital gains reportable to Wisconsin for excess distributions:
- $5,000 (beginning stock basis) + $40,000 (ordinary business income) = $45,000
- $50,000 (distributions from AB) - $45,000 = $5,000 of excess distributions
At the end of the calendar year, electing Tax-Option (S) Corporation AB has the following:
- $40,000 of ordinary business income reportable to Wisconsin
- $30,000 of section 179 expenses to carry forward. The $30,000 of section 179 expenses are suspended until such time that Tax-Option (S) Corporation AB may use them to offset income in a subsequent year in which the election is made.
Note: If the entity-level tax election had not been made, the $30,000 of section 179 expense would have been suspended for Individual Z due to a lack of basis in AB.

Is withholding tax paid by an electing tax-option (S) corporation in another state (e.g., Illinois) on behalf of its members considered a "composite return" for purposes of the Wisconsin entity-level credit for taxes paid to another state?
A tax-option (S) corporation may claim a credit for withholding taxes paid to another state on behalf of a Wisconsin resident shareholder as provided in sec.
71.07(7)(b)3., Wis. Stats., if all of the following apply:
- The law in the other state provides that the Wisconsin resident is not required to file an individual income tax return because the individual's net income tax liability is considered paid in full because of the withholding tax paid by the entity on the Wisconsin shareholder's income attributable to the other state.
- The Wisconsin resident does not file an individual income tax return in the other state.
Caution: Although the individual is not required to file an Illinois income tax return, the individual may file such return with Illinois.
- The income taxed by the other state is attributable to amounts that would be reportable to Wisconsin if the entity-level tax election was not made.
- The tax-option (S) corporation pays the liability shown on the other state's withholding tax return. Amounts paid to the other state are considered paid to that other state only in the year in which the withholding tax return for that state was required to be filed.
- The tax-option (S) corporation includes a copy of the other state's withholding tax return with its Wisconsin Form 5S.
- The credit is claimed within four years of the unextended due date of the entity's return.
For example, Illinois law provides that a nonresident of Illinois who has had Illinois income tax withheld by a tax-option (S) corporation is not required to file an Illinois individual income tax return if the nonresident's income tax liability is paid in full after allowing credit for the withholding.
-
Can a tax-option (S) corporation making the election to pay tax at the entity level exclude income at the entity level if the income is attributable to a tax-exempt shareholder (e.g., employee stock ownership plan)?

71.34(1g), Wis. Stats. According to sec.
1363(b), IRC, taxable income of a tax-option (S) corporation is computed in the same manner as an individual as provided under the IRC.
-
For Wisconsin purposes, how will the tax-option (S) corporation entity-level tax election affect the deductible amount of a shareholder's interest expense related to a debt-financed acquisition of stock of the electing tax-option (S) corporation?
The interest paid by the shareholder is an expense incurred by the shareholder; it is not an expense of the tax-option (S) corporation. The deductibility of the interest expense on the shareholder's Wisconsin income tax return is determined under the Internal Revenue Code (IRC) in effect for Wisconsin. The shareholder may deduct the interest expense to the extent allowable under Internal Revenue Service
Treas. Reg. sec. 1.163-8T and secs.
163(d) and
469, IRC, in effect for Wisconsin, regardless of whether the tax-option (S) corporation makes an election under sec.

-
Where does an electing tax-option (S) corporation report taxable federal, state, and municipal government interest that would have been reported on line 1 of Form 5S if the entity-level tax election was not made?

-

An electing tax-option (S) corporation is allowed to deduct health insurance premiums paid on behalf of a greater than 2-percent shareholder as part of their wage expense. However, the electing tax-option (S) corporation may not claim the self-employed health insurance deduction. The self-employed health insurance deduction is allowed on the shareholder's tax return, and only the shareholder's tax return, just as though the election to pay tax at the entity level was not made. The shareholder does not have an option to forego claiming the self-employed health insurance deduction on the individual return to allow the tax-option (S) corporation to claim the deduction at the entity level.
-
If a shareholder of an electing tax-option (S) corporation had a suspended loss from a prior year due to basis limitations, can the electing tax-option (S) corporation use the shareholder's suspended loss to reduce its Wisconsin taxable income in the current year?
No, an electing tax-option (S) corporation may not use a shareholder's suspended loss from prior years when computing Wisconsin taxable income. Suspended loss due to a basis limitation occurs when a shareholder is disallowed business loss passed-through from a tax-option (S) corporation because the shareholder does not have enough tax basis in the entity.
Note: According to sec. 71.365(1)(b), Wis. Stats., a shareholder's adjusted basis of the shareholder's stock in an electing tax-option (S) corporation is determined as if the election was not made. Therefore, a shareholder with prior year suspended losses due to basis limitations may be able to deduct a portion of the suspended losses in a year the shareholder's basis in the stock of the tax-option (S) corporation increases, regardless of whether the tax-option (S) corporation makes the entity-level tax election.
