SB70,1519 18Section 1519. 71.52 (7) of the statutes is amended to read:
SB70,934,1619 71.52 (7) “Property taxes accrued" means real or personal property taxes or
20monthly municipal permit fees under s. 66.0435 (3) (c), exclusive of special
21assessments, delinquent interest and charges for service, levied on a homestead
22owned by the claimant or a member of the claimant's household. “Real or personal
23property taxes" means those levied under ch. 70, less the tax credit, if any, afforded
24in respect of such property by s. 79.10. If a homestead is owned by 2 or more persons
25or entities as joint tenants or tenants in common or is owned as marital property or

1survivorship marital property and one or more such persons, entities or owners is not
2a member of the claimant's household, property taxes accrued is that part of property
3taxes accrued levied on such homestead, reduced by the tax credit under s. 79.10,
4that reflects the ownership percentage of the claimant and the claimant's household,
5except that if a homestead is owned by 2 or more natural persons or if 2 or more
6natural persons have an interest in a homestead, one or more of whom is not a
7member of the claimant's household, and the claimant has a present interest, as that
8term is used in s. 700.03 (1), in the homestead and is required by the terms of a will
9that transferred the homestead or interest in the homestead to the claimant to pay
10the entire amount of property taxes levied on the homestead, property taxes accrued
11is property taxes accrued levied on such homestead, reduced by the tax credit under
12s. 79.10. A marital property agreement or unilateral statement under ch. 766 has
13no effect in computing property taxes accrued for a person whose homestead is not
14the same as the homestead of that person's spouse. For purposes of this subsection,
15property taxes are “levied" when the tax roll is delivered to the local treasurer for
16collection. If a homestead is sold or purchased during the calendar year of the levy,
17the property taxes accrued for the seller and the buyer are the amount of the tax levy
18prorated to each in proportion to the periods of time each both owned and occupied
19the homestead during the year to which the claim relates. The seller may use the
20closing agreement pertaining to the sale of the homestead, the property tax bill for
21the year before the year to which the claim relates or the property tax bill for the year
22to which the claim relates as the basis for computing property taxes accrued, but
23those taxes are allowable only for the portion of the year during which the seller
24owned and occupied the sold homestead. If a household owns and occupies 2 or more
25homesteads in the same calendar year, property taxes accrued is the sum of the

1prorated property taxes accrued attributable to the household for each of such
2homesteads. If the household owns and occupies the homestead for part of the
3calendar year and rents a homestead for part of the calendar year, it may include both
4the proration of taxes on the homestead owned and rent constituting property taxes
5accrued with respect to the months the homestead is rented in computing the amount
6of the claim under s. 71.54 (1). If a homestead is an integral part of a multipurpose
7or multidwelling building, property taxes accrued are the percentage of the property
8taxes accrued on that part of the multipurpose or multidwelling building occupied
9by the household as a principal residence plus that same percentage of the property
10taxes accrued on the land surrounding it, not exceeding one acre, that is reasonably
11necessary for use of the multipurpose or multidwelling building as a principal
12residence, except as the limitations of s. 71.54 (2) (b) apply. If the homestead is part
13of a farm, property taxes accrued are the property taxes accrued on up to 120 acres
14of the land contiguous to the claimant's principal residence and include the property
15taxes accrued on all improvements to real property located on such land, except as
16the limitations of s. 71.54 (2) (b) apply.
