Late fees are a necessary evil for landlords aw we often need some type of “hammer” to hold over the heads of tenants who pay rent late. With this post I want to provide you with some additional information on the requirements that must be met with regard to late fees as specified in ATCP 134 of the Wisconsin Administrative Code.
A Bit of History:
In the past – prior to ATCP 134 and when the administrative rules pertaining to residential rental housing were called Ag 134 — late fees were not allowed. Because of this creative landlords came up with the idea of offering discounts for the prompt payment of rent. For example, if the tenant pays rent by the 1st of the month the rent will be discounted to $650, however if rent is not received by the 1st of the month then the rental amount will remain at the regular rate of $700. By doing this landlords still were able to obtain a form of late fee without calling it a late fee.
I still see this “discount rent” option on a few of my client’s rental agreements but it has become rare as there is no need to disguise a late fee anymore since late fees are no longer prohibited.
ATCP 134.09(8) Rules Regarding Late Fees:
While late fees are no longer illegal, there are some rules that have been imposed regarding how and when late fees can be used. In the revised Ag Rules (now referred to as ATCP 134) the rules regarding late fees are as follows:
1. You cannot charge a late fee or late penalty unless it is specifically stated in the rental agreement.
2. You may not charge a late fee for the non-payment of a late fee.
3. Before charging a late fee you must apply all rent prepayments received to offset the amount of rent owed by the tenant.
The first two rules are pretty straightforward. However the third rule is a bit confusing. In essence, the third rule is basically saying that you cannot apply a tenant’s rent payment to a past owed late fee so that the tenant would now be considered late in paying the current month’s rent thus allowing you to charge an additional late fee.
Here is an example: Joe Tenant fails to pay you rent for the month of June in the amount of $500. After the 6th of the month you charge Joe a $50 late fee. On or about June 10th Joe pays his rent of $500 for the month of June but fails to pay the $50 late fee. So while Joe has now paid June’s rent in full he still owes you a $50 late fee. When July 1st comes around Joe promptly pays you his July rent of $500. You are not allowed to take Joe’s July rent payment of $500 and apply $50 of that payment to the outstanding $50 late fee for June. This is not allowed because by doing so your actions would now make Joe responsible for paying a late fee for July as well because he would have only paid you $450. You cannot do this.
In the example above you would need to apply the $500 July rent payment to July’s rent and then continue to keep the $50 late fee from June “on the books” and either collect it from Joe in the future or at the end of Joe’s rental term or tenancy deduct the June $50 late fee from Joe’s security deposit (assuming your nonstandard rental provisions allow you to do so).
While it may be tempting to ignore this administrative rule you must remember that by ignoring the rule you will be in violation of ATCP 134 which would allow Joe Tenant, under §100.20(5) Wis Stats., to recover twice the amount of the loss (in this case $100) plus his costs in filing the lawsuit and his attorney’s fees (and trust me these will be more than the $100 ; )
The three rules mentioned above are administrative rules and apply statewide. You must also be aware that many municipalities have created additional rules regarding late fees. An example would be the City of Madison which specifies that a late fee cannot exceed more than 5% of the rent amount. So be sure and check the local administrative ordinances where you own your rental property.

Hi Tristan, I love your blog. Could you weigh in on the legality of late fees assessed against unpaid “last month’s rent” or unpaid “security deposits”?
I think requiring “last month’s rent” is a bit like a security deposit, it’s not true rent. Can late fees be charged on this if it’s not paid?
Let’s not get into how the tenant was able to move in
Thanks!

Hi Kate — Thanks for your question. I would not charge a late fee for an unpaid security deposit. I have never had that issue before a court so I can’t give you any past experience on that issue. I personally never let a tenant move into my rental property until I received a full security deposit. I don’t even let them sign a rental agreement until I know they are prepared to pay the security deposit in full.
You are correct that in Wisconsin anything over and beyond the first month’s rent is considered to be a security deposit. So while you can require a tenant to post 1st and last month’s rent and security deposit. If they would break the lease mid-term, you would need to treat the last month’s rent as security deposit and comply with ATCP 134 re same.

If rent is due on the first, can I charge a late fee on the second or is there a legal grace period that I have to abide by? In my lease, it states that rent is due on the first and that there is a $5/day late fee charge. I’ve never had a problem with this until my current tenant objected. I’ve read ATCP 134 and didn’t see anything about a grace period, but I could have overlooked it. Thanks!

Tommy — Thanks for your question. No there is no statutory prrescribed grace period. You can have a late fee “kick in” on the 2nd if you want. Most landlords seem to have a late fee commence on the 5th. I personally have mine start on the 3rd of the month for my tenants. But your tenant is wrong — you can have your late fee commence on the 2nd if you wish.

Hi, I love your blog and thanks for having it. I have a question, in my lease from WI legal blank I have late fees that occur if rent is not paid on the 6th. If paid of the 7th then they are charged a $20 fee and then $3 per day thereafter. Well lets say I accept a portion of the rent, can I instead of giving them a 5 day charge them a proprated late fee on the unpaid portio? I think this then would encourage them to pay as much as they can which in turn is beneficial to me. Also as I understand late fees are considered rent in the updated 2010 lease from Wi legal blank, so my question is I can withhold late fees from their security deposit correct? Thanks so much!

Marsha — I draft teh Wisconsin LEgal Blank leases. There is no Wisconsin case, statute or regulation that limits the amount of a late fee, however if your rental is in Milwaukee COunty I can tell you that the Milw. Co. court commissioners will not give you more than $50 late fee. they frown upon daily late fees.
I’m not sure that I understand your questiosn about pro-rating late fee instead of giving a 5 day notice. Please note however that in Milwaukee County again (even though late fees are considered rent) the court commissioenrs have not been allowing you to include late fees onthe 5 day notice. I did add that clause to the revised lease however to assist landlords who may want to challenge that.
Late fees can be deducted from a tenant’s security deposit as long as (1) the late fee in written in the rental agreement, and (2) you list the late fee in the nonstandard rental provisions document (which lists items that can be deducted from a tenant’s security deposit.
Thanks for the kind words about the blog. I am glad that is has been helpful.
