Security Deposit Basics for Landlords: What to Know Before You Collect a Dime
Limits, holding the money, documenting condition, lawful deductions, return deadlines, and tax treatment. Plus a checklist of what to look up in your state.
Security deposits cause more landlord-tenant disputes than almost anything else, and most of those disputes are avoidable. The rules aren't complicated once you know them. The catch is that they're set mostly by state (and sometimes city) law, and they vary widely.
This guide covers the concepts every small landlord should understand, then gives you a checklist of exactly what to look up for your property's location.
Not legal or tax advice. Check your state law. Security deposit rules differ by state and sometimes by city or county, and penalties for getting them wrong can be steep (some jurisdictions allow tenants to recover a multiple of the deposit). Read your state's statute, check local ordinances, and consult a local attorney if you're unsure.
What a security deposit is (and isn't)
A security deposit is money a tenant gives you at the start of a tenancy to secure their obligations under the lease, typically unpaid rent and damage beyond normal wear and tear. It's still the tenant's money until you have a lawful reason to keep some or all of it.
That framing explains most of the rules: you're holding someone else's money, so the law sets standards for how you hold it, what you can take, and how fast you give the rest back.
1. How much you can charge
Many states cap security deposits, often as a multiple of monthly rent (for example, one or two months' rent). Others have no cap. Some caps differ for furnished units, tenants with pets, or older tenants, and some cities set stricter limits than their state.
Also check whether your state treats "last month's rent," pet deposits, or non-refundable fees as part of the deposit for cap purposes. Some states don't allow non-refundable deposits at all.
2. Where and how you hold it
Depending on your state, you may be required to:
- Keep deposits in a separate account (sometimes a separate account per tenant, sometimes in an in-state bank)
- Tell the tenant in writing where the deposit is held
- Pay interest on the deposit, at a rate set by statute or tied to what the account earns, either annually or at move-out
Even where none of this is required, a separate account is good practice. It keeps tenant money out of your operating cash and makes your records clean.
3. Document condition at move-in
The deposit fight is usually won or lost on move-in day. Do a move-in inspection with the tenant if you can:
- Go room by room with a written checklist covering walls, floors, appliances, fixtures, windows, and so on
- Take dated photos and video of every room, including close-ups of existing damage
- Have the tenant sign and date the checklist, and give them a copy
Some states require a written move-in condition report or a specific statement given to the tenant. The move-in/move-out checklist in the Landlord Operations Kit (see the Toolkit) gives you a starting structure.
4. What you can (generally) deduct
The usual lawful categories are:
- Unpaid rent and other amounts owed under the lease
- Damage beyond normal wear and tear
- Sometimes cleaning needed to return the unit to its move-in condition. Some states limit this.
Normal wear and tear generally can't be deducted. The line isn't always crisp, but here's the general idea:
| Usually normal wear and tear | Usually damage |
|---|---|
| Faded paint, minor scuffs | Large holes, unapproved paint colors |
| Carpet worn from normal walking | Pet stains, burns, tears |
| Loose door handle from use | Broken door or frame |
| A few small nail holes | Broken windows or blinds |
Age matters, too. Carpet that was already near the end of its useful life when it was damaged usually can't be charged at full replacement cost. Charge reasonable, documented amounts and keep invoices.
5. Returning the deposit: deadlines and itemization
After move-out, most states require you to return the deposit, or the balance plus an itemized statement of deductions, within a set number of days. That deadline commonly runs anywhere from a couple of weeks to a month or more depending on the state. Some states also require:
- Sending it to the tenant's forwarding address (ask for one in writing)
- Receipts or estimates for repairs over a certain amount
- Advance notice of a pre-move-out inspection
Missing the deadline or skipping the itemization can cost you your right to keep any of the deposit, and in some places it adds penalties. Put the deadline on your calendar the day the tenant gives notice.
6. When you sell the property
If you sell a rental, the deposits usually need to be transferred to the new owner (with notice to the tenants) or returned. Check your state's rule and make sure it's handled in your closing.
7. Taxes on security deposits
Under IRS guidance in Publication 527, Residential Rental Property:
- A security deposit you plan to return generally isn't included in income when you receive it.
- If you keep part or all of it because the tenant didn't meet the lease terms, the amount you keep is generally income in the year you keep it.
- If the "deposit" is really advance rent (for example, it'll be applied to the final month's rent), it's generally income when you receive it.
That's why your books should track deposits as a liability (money you owe back), not as rent. See our expense tracking spreadsheet guide and Schedule E categories for how to set that up. Confirm the treatment with your tax preparer.
Your state-law checklist
Look up each of these for your property's state and city or county:
- Is there a maximum deposit? Does it differ for furnished units or pets?
- Are non-refundable fees or deposits allowed?
- Must deposits be held in a separate or specific account, and must you disclose where?
- Do you have to pay interest? At what rate, and how often?
- Is a move-in condition report required?
- What's the return deadline after move-out?
- What must the itemized statement include, and how must it be delivered?
- Is a pre-move-out inspection required or allowed on request?
- What are the penalties for non-compliance?
- What happens to deposits when you sell?
Good places to start: your state's landlord-tenant statute, your state attorney general's or housing agency's tenant/landlord guide (many publish free ones), and a local landlord association.
The bottom line
Collect only what's allowed, hold it properly, document condition thoroughly, deduct only for lawful, documented reasons, and return it on time with an itemized list. Do that, and deposit disputes become rare and winnable.
