Wisconsin Security Deposit
Return Calculator

Wisconsin does not impose a statutory limit on the amount a landlord can collect as a security deposit. However, the state does regulate the return process: landlords must return deposits within 21 days and provide an itemized list of any deductions.

The state does not require landlords to pay interest on deposits. The governing statute is Wis.

Stat. § 704.28; ATCP 134.06.

While the lack of a deposit cap gives Wisconsin landlords more flexibility in setting deposit amounts, tenants still have important protections during the return process. Landlords who fail to return deposits on time or who make improper deductions face penalties: tenant may recover double the deposit wrongfully withheld plus attorney fees.

The absence of a deposit limit makes it especially important for Wisconsin tenants to understand what constitutes a lawful deduction and how to dispute excessive charges.

Wisconsin's Security Deposit Rules (Wis. Stat.

§ 704.28 and ATCP 134.06) expressly provide that landlords cannot deduct for 'normal depreciation' or 'normal wear and tear of carpets and other flooring' — one of the most explicit prohibitions in the nation. Wisconsin's Rental Unit Energy Disclosure requirement (ATCP 134.04) requires landlords to provide energy cost information — non-compliance can be raised in deposit disputes as evidence of regulatory violations.

Milwaukee and Madison do not have local rent control modifying state deposit rules, though both have active tenant advocacy. Wisconsin's small claims limit is $10,000.

Wisconsin's ATCP 134 rules, enforced by the Wisconsin Department of Agriculture, Trade and Consumer Protection, allow tenants to file administrative complaints as an alternative to civil litigation.

Wisconsin is one of the states that does not impose a statutory cap on security deposit amounts. Landlords have discretion to set the deposit at whatever amount they choose, though market forces and competition for tenants typically keep deposits in the range of one to two months' rent.

Unlike the roughly half of states that limit deposits to a specific number of months' rent, Wisconsin leaves this to negotiation between landlord and tenant.

Even without a statutory cap, Wisconsin tenants can negotiate deposit amounts. A strong rental history, good credit score, or willingness to sign a longer lease can provide leverage for a lower deposit.

Tenants should always get the deposit amount in writing as part of the lease agreement and request a receipt showing the exact amount paid and the date of payment.

Wisconsin tenants should be aware that security deposits are separate from other move-in costs. Application fees, pet fees, cleaning deposits, and last month's rent are distinct charges that may or may not be subject to separate regulations.

Read your lease carefully to understand exactly what each payment covers and whether it is reimbursable.

Wisconsin law requires landlords to return security deposits within 21 days after the tenant vacates the rental unit. This deadline is strict — Wisconsin's return window is shorter than the national average, which falls around 30 days.

The clock typically starts when the tenant surrenders possession of the unit and returns all keys.

Along with the deposit (or any remaining balance after deductions), the landlord must provide an itemized written statement listing each deduction. Wisconsin law specifically requires this itemization, and failure to provide it within the statutory window can result in the landlord forfeiting the right to retain any portion of the deposit.

Each deduction must be documented — vague entries like "cleaning" or "damages" without specifics are generally insufficient.

To protect your rights as a tenant in Wisconsin, always provide your landlord with a forwarding address in writing when you move out. Some states require the forwarding address before the return deadline begins to run.

Take date-stamped photos or video of the unit at both move-in and move-out to document the property's condition. If the landlord fails to return the deposit or provide an itemization within 21 days, send a written demand letter via certified mail before pursuing legal action.

Under Wisconsin law, landlords may deduct from the security deposit for the following: unpaid rent, physical damage beyond normal wear and tear (not cleaning or carpet wear). These deductions must be reasonable, documented, and itemized in the statement provided to the tenant.

Landlords cannot deduct for normal wear and tear — this is a critical distinction that is frequently disputed between landlords and tenants.

Normal wear and tear in Wisconsin generally includes minor scuffs on walls, worn carpet from everyday foot traffic, small nail holes from hanging pictures, faded paint due to sunlight exposure, and minor door or window wear. Damage beyond normal wear includes large holes in walls, stained or burned carpet, broken windows, unauthorized modifications, pet damage, and excessive filth requiring professional cleaning.

The line between wear and damage is not always clear, which is why move-in and move-out condition documentation is critical.

While Wisconsin does not require a formal walk-through inspection before move-out, tenants can request one. A pre-move-out inspection gives you the chance to fix any issues the landlord identifies, potentially saving deductions from your deposit.

Even without a formal requirement, conducting your own thorough inspection with date-stamped photos on the day you move out creates a strong evidence trail if you need to dispute deductions later.

Wisconsin does not require landlords to pay interest on security deposits. No interest requirement.

This places Wisconsin in the majority — only 14 of 51 jurisdictions require deposit interest. While tenants do not earn interest on their deposits in Wisconsin, they still have full rights to the return of the principal amount, less any lawful deductions.

Even without an interest requirement, Wisconsin tenants should be aware that their deposit money is being held for the duration of the lease. This represents a real opportunity cost, particularly for larger deposits.

When negotiating a lease in Wisconsin, consider whether the deposit amount is reasonable relative to the monthly rent and whether any of the upfront costs can be reduced.

Wisconsin does not require landlords to hold security deposits in a separate or escrow account. This means a landlord may commingle the deposit with personal or business funds, which carries some risk for tenants if the landlord faces financial difficulties.

Approximately 16 jurisdictions require separate accounts for deposit funds. Wisconsin tenants may want to ask their landlord where the deposit is being held, even though disclosure is not always required by law.

The penalties for security deposit violations in Wisconsin are significant. Under Wis.

Stat. § 704.28; ATCP 134.06: tenant may recover double the deposit wrongfully withheld plus attorney fees.

These penalties apply when a landlord fails to return the deposit within the statutory deadline, makes improper deductions, or fails to provide the required itemized statement.

Wisconsin's double-damages provision means that a landlord who wrongfully withholds a $2,000 security deposit could owe $4,000 to the tenant, plus any attorney fees and court costs awarded. This penalty applies when the landlord's withholding is found to be willful or in bad faith — an honest mistake in calculating deductions may not trigger the penalty multiplier, but failing to return the deposit at all almost certainly will.

To pursue a security deposit claim in Wisconsin, tenants typically file in small claims court, which handles disputes up to a specified dollar amount without requiring an attorney. The process involves filing a complaint, paying a small filing fee, and presenting evidence at a hearing.

Key evidence includes the lease, proof of deposit payment, move-in and move-out photos, the landlord's itemized deductions statement (or lack thereof), and any correspondence about the deposit. Many Wisconsin courts also offer mediation services that can resolve deposit disputes faster than a full hearing.

Security deposit disputes are often part of a broader landlord-tenant conflict. If the dispute escalates to eviction, the Wisconsin Eviction Timeline Calculator shows notice periods and court timelines by cause of action.
