An applicant has a dog. You want $500 for it. There are three completely different ways to collect that $500, and landlords routinely pick one, write a different one on the lease, and book a third.
- A pet deposit — refundable, held against damage
- A pet fee — non-refundable, charged once for the privilege
- Pet rent — a recurring monthly amount added to rent
Same dog, same $500, three different lines on your books, three different tax answers. Only one of them is money you might have to give back.
The three, side by side
| Refundable? | Books as | Taxable | |
|---|---|---|---|
| Pet deposit | Yes | Liability (money you hold) | Not on receipt — only when forfeited or applied |
| Pet fee | No | Income on receipt | The year you collect it |
| Pet rent | No | Recurring income | Each month, as billed |
If you take nothing else from this: a deposit is not income and a fee is not refundable. Every mistake below is some version of blurring those two.
The pet deposit
A pet deposit is a security deposit that happens to be about an animal. The accounting is identical — cash goes up, and so does what you owe:
Dr 1200 Security Deposits Held (asset) 500.00
Cr 2100 Security Deposits Liability 500.00
Nothing touches income. Your P&L doesn't move, because you're not any richer — you're holding someone else's money and you may well be handing it back.
Two consequences people miss. First, in most states a pet deposit counts against the statutory cap on total deposits. If your state limits deposits to one month's rent and you already hold a full month, there's no room left for a pet deposit — the charge you're allowed to make is a fee or pet rent instead. Second, if you're required to hold deposits in a separate trust account, the pet portion goes there too. It isn't operating cash.
A "non-refundable pet deposit" is not a thing in every state, and where it isn't, calling it one doesn't help you. Some states hold that anything named a deposit is refundable by definition, no matter what the lease says. If you mean a fee, write fee.
The pet fee
A non-refundable pet fee is ordinary rental income the moment it lands:
Dr 1000 Cash 300.00
Cr 4250 Pet Fee (income) 300.00
It goes on Schedule E as rents received in the year you collect it — see the Schedule E walkthrough for where. There's no liability, no trust account, no return obligation, and nothing to reconcile at move-out.
That last point cuts both ways. A fee is clean, but it is not a reserve. Having collected $300 in pet fees does not entitle you to keep $300 of the security deposit at move-out — the fee bought the privilege of having the animal, not a prepaid allowance for what it chews. Damage still comes out of the deposit, itemized, with the burden of proof on you.
Pet rent
Pet rent is a recurring charge on the lease — same as a parking space or a utility bundle. Each month it bills alongside rent and posts as income:
Dr 1100 Accounts Receivable 25.00
Cr 4250 Pet Fee (income) 25.00
Set it up as a real recurring line, not by quietly raising the rent number. Two reasons: the tenant can see what they're paying for, and when the animal leaves mid-lease you can stop one charge instead of renegotiating rent. It also keeps your rent roll honest — a unit that rents for $1,200 with $25 of pet rent is a $1,200 unit, and blending them makes every per-unit comparison you run slightly wrong.
Substance beats the label
The recurring theme in every audit and every deposit dispute: what you called it doesn't decide what it is. A "deposit" you never intend to return is a fee, and if you booked it as a liability you have understated income. A "fee" your state requires you to refund is a deposit, and if you booked it as income you have both an overstated tax bill and a liability you can't produce a number for.
Pick the treatment first, then name the charge to match, then write the lease to match that. In that order.
The charge you cannot make
Under the Fair Housing Act, an assistance animal is not a pet. That covers service animals and support animals alike, and HUD's guidance on it — Notice FHEO-2020-01, on assessing a request to have an animal as a reasonable accommodation — is the document to read before you write a pet policy.
When a request is granted, you may not charge a pet deposit, a pet fee, or pet rent. You also may not apply pet weight limits or breed restrictions to the animal. The handler remains fully liable for any damage the animal actually causes, which you handle at move-out like any other damage — through the regular security deposit, with an itemized statement.
This is where bookkeeping becomes evidence. If a fair-housing complaint is filed, one of the first things asked for is the ledger — and a Pet Fee line against a tenant with an approved accommodation is not something you can explain away in a deposition. Conversely, a clean ledger showing the charge was never billed, or was reversed on the date the accommodation was approved, is the strongest exhibit you have.
So when you approve an accommodation mid-lease, close the recurring charge and reverse anything already billed that day, and let the dated entry stand as the record. "We stopped collecting it eventually" is a much worse answer than a reversal with a timestamp.
At move-out
Nothing about a pet changes the disposition rules, and that trips people up. The pet deposit and the regular deposit are both deposits: you itemize actual damage, you depreciate rather than charging full replacement, and you return the balance inside your state's deadline — commonly 14 to 30 days.
Pet damage is where the wear-versus-damage line gets argued most. Traffic-lane wear on a carpet is wear. Urine through to the pad is damage — but if that carpet had a seven-year life and was five years old, you're owed the remaining two years of value, not a new carpet. Photograph the unit at move-in and again at move-out; in most disputes it's the landlord who has to prove the deduction was justified.
Doing this without a ledger
The spreadsheet failure here is specific. Pet money arrives in three shapes, gets deposited in one account, and a year later nobody can say which part of the balance is refundable. Then a tenant moves out, you refund what feels right, and the deposits you think you hold stop matching the trust account with no way to reconstruct why.
Corbica's default chart ships this already separated — 2100 Security Deposits Liability as a trust liability for anything refundable, 4250 Pet Fee for anything that isn't, and pet rent as a named recurring charge on the lease so it bills itself and reads correctly on the rent roll. The trust reconciliation then answers the only question that matters: does what you owe match what's in the account?
Whatever you use, the principle is the one from the deposit post: money you may have to give back is a liability, and your books should say so on the day it arrives.
