Security Deposit Basics for Landlords: Collecting, Holding, Returning and Record-Keeping

A security deposit is the tenant’s money that you’re holding. You don’t earn it, and you can only keep part of it for reasons the lease and state law allow. Most deposit disputes come from two avoidable problems: missing documentation of the unit’s condition, and missed state deadlines for returning it. This guide covers the full lifecycle and the record-keeping that prevents both.

State and local law controls almost everything about deposits, and penalties for getting it wrong can be several times the deposit in some places. Look up your state’s landlord-tenant statute or official handbook (often from the attorney general or housing agency), check city rules too, and ask a local attorney if anything is unclear. This guide is educational, not legal advice.

The six things that vary by state

Before you collect a dollar, find your jurisdiction’s answer to each of these and write it on a one-page cheat sheet in your property folder:

Question Why it matters
Is there a maximum deposit? (often expressed as a number of months’ rent) Collecting more than allowed can trigger penalties
Where must the deposit be held? (separate account, trust account, interest-bearing account) Some states require a separate or interest-bearing account and written notice of where it’s held
Is interest owed to the tenant? Some states and cities (Massachusetts and New Jersey among them, plus a number of cities) require interest. Rules on rates and timing vary
What receipts or notices are required at move-in? Some states require a written receipt, a condition statement, or disclosure of the bank holding the funds
How soon must it be returned after move-out? Deadlines vary widely, roughly from two weeks to two months depending on the state
What must the itemized statement include, and how must it be delivered? Missing the format or deadline can forfeit your right to deduct anything

Also check whether your state treats “last month’s rent” collected upfront differently from a security deposit, and whether non-refundable fees (pet fees, cleaning fees) are allowed at all.

At lease signing: collect it cleanly

  • Deposit amount stated in the lease, within any legal cap
  • Payment received in a traceable form (bank transfer, platform payment, check, or cash with a written receipt)
  • Written receipt given, with any required disclosures (account location, interest terms)
  • Move-in inspection completed and signed. Use our inspection checklist
  • Deposit recorded in your books as a liability, not as rent income

While you hold it: keep it separate

Even where the law doesn’t require a separate account, keeping deposits separate is good practice:

  1. A dedicated deposit savings account (one for all units is fine if your state allows it) with nothing else in it.
  2. A deposit register, a simple table listing each tenant, unit, amount, date received, account, any interest owed and date returned.
  3. Never use deposits for repairs or mortgage payments during the tenancy. If you have to pay it back and the money is gone, that’s a cash crunch and possibly a legal problem.
Unit Tenant Amount Received Held in Interest terms Returned Amount returned Deductions
123 Main #1 J. Doe $1,800 2026-08-01 Deposit savings Per state rule — — —

Tax note: a deposit you plan to return generally isn’t rental income when you receive it. If you keep some or all of it, for unpaid rent or damages, that amount is generally income in the year you keep it. A deposit that’s really last month’s rent is generally income when received. See IRS Publication 527 and check with a tax professional about your situation.

At move-out: the four-step process

1. Inspect against the move-in record

Walk the unit with your move-in checklist and photos, shoot the same angles, and note differences. Separate normal wear and tear (generally your cost) from damage and unpaid charges (potentially deductible). Our inspection guide has a table of common examples.

2. Price deductions with evidence

For each deduction, have one of these: an invoice for work done, a written contractor quote, or a documented reasonable charge for your own labor where your state allows it. Prorate replacements by age. A carpet near the end of its useful life isn’t worth its full replacement cost.

3. Write the itemized statement

A clear statement prevents most disputes. A simple format:

Security Deposit Itemization Property: 123 Main St, Unit 1 · Tenant(s): J. Doe · Lease end: 2026-07-31 · Keys returned: 2026-07-31 Forwarding address on file: [address]

Item Description / evidence Amount
Deposit held $1,800.00
Interest owed (if applicable) Per [state/city] rule +$0.00
Unpaid rent July utility reimbursement per lease §7 −$64.20
Wall repair, bedroom 2 Three 2-inch holes; invoice #1043 attached −$145.00
Cleaning Oven and refrigerator; move-in photos show clean; invoice attached −$90.00
Refund due $1,500.80

Refund sent [date] by [method]. Questions: [contact].

Attach photos and invoices, or state that they’re available on request, depending on what your state requires.

4. Deliver on time, with proof

  • Calendar the state deadline the day the tenant gives notice.
  • Send the statement and refund to the forwarding address by a method you can prove: certified mail, a tracked carrier, or an electronic method if your lease and state law allow it.
  • Keep the proof of mailing with the statement.

Records to keep for every deposit

Document When created
Lease clause and receipt for the deposit Move-in
Signed move-in checklist, photos, video Move-in
Deposit register entry and bank account statement Move-in, monthly
Any interest calculations and payments Annually or at move-out
Move-out checklist, photos, video Move-out
Invoices or quotes for each deduction Move-out
Itemized statement, refund record, proof of delivery Move-out

Store them all in the tenant’s folder within the property’s records (see how to organize rental records), and keep them for several years after the tenancy ends, or longer if your attorney recommends it.

Common mistakes

  • Treating the deposit as income and spending it during the lease.
  • Deducting for normal wear and tear, like repainting after a multi-year tenancy or replacing old carpet at full price.
  • Missing the return deadline because nobody calendared it.
  • No move-in documentation, which leaves you with nothing to compare at move-out.
  • Vague statements (“cleaning: $300”) with no evidence attached.

Handled well, the deposit process is mostly paperwork done at the right time.
