A tenant sends you first month's rent plus a $1,200 security deposit. Most small landlords deposit the whole amount, categorize it as "rental income," and move on.
That's wrong twice: it overstates your taxable income, and it quietly destroys the record you'll need if the deposit is ever disputed.
The deposit isn't yours
A security deposit is money you're holding on someone else's behalf. You have possession; the tenant still has a claim on it. In accounting terms that's a liability — something you owe — not income.
The moment the money arrives, your books should say two things at once:
- Cash went up by $1,200 (asset increases)
- You now owe a tenant $1,200 (liability increases)

Cr 2300 Security Deposits Held (liability) 1,200.00
Nothing hits income. Your P&L doesn't move. That's correct — you're no richer than you were an hour ago.
Book it as income instead and you've inflated your revenue by $1,200, overstated your tax bill for the year, and created a number you'll have to unwind later.
Why "I'll just remember" fails
Deposits are held for years. Over a five-unit portfolio and a few tenant turnovers, "which of this cash is mine and which is theirs" stops being answerable from memory, and the bank balance alone can't tell you.
The test that matters: at any moment, can you produce a number for total deposits held, and does it match what's actually in the account? If those two figures disagree, you have a problem — and you want to find it on a Tuesday afternoon, not in a small-claims hearing.
That reconciliation is trivial when deposits are a liability account. It's essentially impossible when they were booked as income eighteen months ago.
Trust accounts and state rules
Many states require deposits be held in a separate account, and a good number require the account be interest-bearing with interest credited to the tenant. Requirements vary widely — some states specify the bank must be in-state, some cap what you may deduct, most impose a hard deadline (commonly 14–30 days after move-out) for returning the balance with an itemized statement.
Miss the deadline and the penalty in many states isn't just returning the deposit — it's two or three times the deposit, plus the tenant's legal fees. This is one of the few areas where sloppy bookkeeping converts directly into statutory damages.
Check your own state's rule and diary the deadline the day the tenant gives notice. Don't rely on remembering it during a turnover.
If you're required to hold deposits separately, your books should mirror that: a dedicated trust asset account that maps to the real bank account, reconciled like any other.
Move-out: where the entries actually happen
At move-out you're doing three things — determining what's owed, applying the deposit to it, and returning the rest.
Say the $1,200 deposit meets $450 in damage beyond normal wear and $300 in unpaid rent.
1. Record what the tenant owes you. Damage recovery is income; unpaid rent was likely already billed.
Dr 1300 Accounts Receivable — Tenant 450.00
Cr 4200 Damage Recovery Income 450.00
2. Apply the deposit against those charges. This is where the liability finally comes off your books — you no longer owe that portion back.
Dr 2300 Security Deposits Held 750.00
Cr 1300 Accounts Receivable — Tenant 750.00
3. Return the balance.
Dr 2300 Security Deposits Held 450.00
Cr 1200 Security Deposit Trust (asset) 450.00
The liability is now zero for that tenant, the trust account is down by the full $1,200, and $450 of damage recovery shows up as income in the year you actually earned it — not the year the deposit arrived.
Normal wear and tear is not damage
The most litigated question in this whole area. The general line: wear is what happens when a reasonable tenant lives somewhere normally; damage is what happens when they don't.
| Usually wear (not deductible) | Usually damage (deductible) |
|---|---|
| Faded paint, minor scuffs | Holes in drywall, crayon murals |
| Carpet worn in traffic lanes | Burns, pet stains through to pad |
| Loose door handles | Broken doors, missing fixtures |
| Minor nail holes from pictures | Anchors ripped out of the wall |
Two practical rules. Depreciate, don't charge full replacement — if carpet has a seven-year life and the tenant ruined it in year five, you're owed the remaining two years of value, not a whole new carpet. And document with dated photos at move-in and move-out, because in most disputes the landlord carries the burden of proving the deduction was justified.
The forfeiture case
When a tenant abandons the unit or the deposit is fully applied to what they owe, the deposit converts to income at that point — and only that point. The entry is the same as step 2 above: the liability comes down, offset against the receivable. What you must not do is quietly reclassify the whole deposit to income and skip recording the charges, because then you've got income with no supporting detail and no itemized statement to send.
Doing this without a ledger
If you're tracking deposits in a spreadsheet, the failure mode isn't dramatic — it's slow. A tenant moves out, you refund from whichever account had the cash, the spreadsheet doesn't get updated, and two years later the total you think you hold and the total actually sitting in the trust account differ by a few hundred dollars, with no way to reconstruct why.
Held as a real liability account against a real trust asset account, the answer is one report: deposits held per tenant, total, versus the bank. Corbica keeps that as a first-class thing — deposits post to their own liability account, move-out deductions run through the entries above, and the trust reconciliation tells you whether book and bank agree.
Whatever you use, the principle doesn't change: that money is the tenant's until you can prove otherwise, and your books should say so.
General information, not legal or tax advice. Security deposit law is state-specific and the penalties for getting it wrong are real — check your state's statute or ask a local attorney.
