“Property taxes accrued” means real property taxes or monthly municipal permit fees under s. 66.0435 (3) (c), exclusive of special assessments, delinquent interest and charges for service, levied on a homestead owned by the claimant or a member of the claimant’s household. “Real property taxes” means those levied under ch. 70, less the tax credit, if any, afforded in respect of such property by s. 79.10. If a homestead is owned by 2 or more persons or entities as joint tenants or tenants in common or is owned as marital property or survivorship marital property and one or more such persons, entities or owners is not a member of the claimant’s household, property taxes accrued is that part of property taxes accrued levied on such homestead, reduced by the tax credit under s. 79.10, that reflects the ownership percentage of the claimant and the claimant’s household, except that if a homestead is owned by 2 or more natural persons or if 2 or more natural persons have an interest in a homestead, one or more of whom is not a member of the claimant’s household, and the claimant has a present interest, as that term is used in s. 700.03 (1), in the homestead and is required by the terms of a will that transferred the homestead or interest in the homestead to the claimant to pay the entire amount of property taxes levied on the homestead, property taxes accrued is property taxes accrued levied on such homestead, reduced by the tax credit under s. 79.10. A marital property agreement or unilateral statement under ch. 766 has no effect in computing property taxes accrued for a person whose homestead is not the same as the homestead of that person’s spouse. For purposes of this subsection, property taxes are “levied” when the tax roll is delivered to the local treasurer for collection. If a homestead is sold or purchased during the calendar year of the levy, the property taxes accrued for the seller and the buyer are the amount of the tax levy prorated to each in proportion to the periods of time each both owned and occupied the homestead during the year to which the claim relates. The seller may use the closing agreement pertaining to the sale of the homestead, the property tax bill for the year before the year to which the claim relates or the property tax bill for the year to which the claim relates as the basis for computing property taxes accrued, but those taxes are allowable only for the portion of the year during which the seller owned and occupied the sold homestead. If a household owns and occupies 2 or more homesteads in the same calendar year, property taxes accrued is the sum of the prorated property taxes accrued attributable to the household for each of such homesteads. If the household owns and occupies the homestead for part of the calendar year and rents a homestead for part of the calendar year, it may include both the proration of taxes on the homestead owned and rent constituting property taxes accrued with respect to the months the homestead is rented in computing the amount of the claim under s. 71.54 (1). If a homestead is an integral part of a multipurpose or multidwelling building, property taxes accrued are the percentage of the property taxes accrued on that part of the multipurpose or multidwelling building occupied by the household as a principal residence plus that same percentage of the property taxes accrued on the land surrounding it, not exceeding one acre, that is reasonably necessary for use of the multipurpose or multidwelling building as a principal residence, except as the limitations of s. 71.54 (2) (b) apply. If the homestead is part of a farm, property taxes accrued are the property taxes accrued on up to 120 acres of the land contiguous to the claimant’s principal residence and include the property taxes accrued on all improvements to real property located on such land, except as the limitations of s. 71.54 (2) (b) apply.
