Tenant Security Deposit Accounting & Tax Rules
Security deposits are one of the most misunderstood items in rental property accounting. Sometimes they're income, sometimes they're not, and some states require you to pay interest on them. Here's how to handle them correctly.
In This Guide
1. When Security Deposits Are Income
Per IRS Publication 527, a security deposit is taxable income in these situations:
Applied to last month's rent
If the lease states the deposit will be used as the final month's rent, it's income in the year received — not the year applied. This is because you have unrestricted use of the funds.
Deposit forfeited for damages
When a tenant moves out and you keep all or part of the deposit for damages beyond normal wear and tear, the amount retained becomes income in the year you keep it.
Applied to unpaid rent
If you use the deposit to cover months where rent wasn't paid, the amount used becomes rental income in the year applied.
Non-refundable "deposits"
Any upfront payment labeled as a "deposit" but which is non-refundable (move-in fee, pet fee, cleaning fee) is income in the year received. The label doesn't matter — the refundability does.
Key Rule: A deposit is income when you gain unrestricted use of the funds OR when the tenant loses the right to get it back. If you're simply holding it as security and must return it when the lease ends, it's NOT income.
2. When They're NOT Income
A refundable security deposit held in trust for the tenant is not taxable income because you have an obligation to return it. This applies when:
- The deposit is held as security against potential damages
- The tenant has a right to receive it back (subject to damage deductions)
- You haven't applied it to rent or forfeited it for damages
- You maintain it in a separate account (required in many states)
Think of it as a liability on your books — you owe it back to the tenant. It only converts to income when the obligation to return it is extinguished.
3. Damage Offsets & Deductions
When a tenant moves out and you retain part of the deposit for repairs, here's how the tax math works:
Example: $2,000 Security Deposit
Tenant caused $800 in damage (broken blinds, stained carpet, hole in wall).
You keep $800 and return $1,200 to the tenant.
Tax Treatment:
- - Report $800 as rental income (Line 3, Schedule E)
- - Deduct $800 in repair expenses (Line 14, Schedule E)
- - Net tax impact: $0 (income and deduction cancel out)
Important: You must report BOTH the income (deposit retained) AND the expense (repair cost). Don't just net them. Even though the net effect is zero, failing to report the income could trigger an IRS notice if the deposit shows on a 1099 or bank record. The deduction offsets it.
If the actual repair cost exceeds the deposit retained (e.g., $1,500 in repairs but only kept $800), you still deduct the full $1,500 in repair expenses and only report $800 in income. The excess repair cost reduces your net rental income.
4. State Interest Requirements
Many states require landlords to pay interest on security deposits held for more than a specified period. Failure to pay interest can result in penalties, forfeiture of the deposit, or liability for damages.
| State | Interest Required? | Notes |
|---|---|---|
| California | No (statewide) | Some cities require it (SF, LA, Berkeley) |
| Illinois | Yes (25+ units) | Rate set annually by state comptroller |
| Maryland | Yes | 3% or US Treasury rate, whichever is higher |
| Massachusetts | Yes | 5% annually or actual bank rate earned |
| New Jersey | Yes | Must be in interest-bearing account |
| New York | Yes (6+ units) | Prevailing bank rate minus 1% admin fee |
| Texas | No | No separate account required either |
| Florida | Optional | 75% of annualized rate or 5% simple interest |
Tax treatment of interest paid: Interest you pay to tenants on their security deposits is a deductible expense (Schedule E Line 13 — Other Interest). Interest earned on the deposit account is reportable income to you (even if you pass it to the tenant).
5. Proper Bookkeeping Treatment
Security deposits should be tracked as a liability, not income, until disposition. Here's the correct accounting:
When Received
Debit: Security Deposit Bank Account ... $1,500
Credit: Security Deposit Liability ... $1,500
When Returned (No Damage)
Debit: Security Deposit Liability ... $1,500
Credit: Security Deposit Bank Account ... $1,500
When Partially Retained ($400 Damage)
Debit: Security Deposit Liability ... $1,500
Credit: Security Deposit Bank Account ... $1,100 (returned)
Credit: Rental Income ... $400 (retained)
6. Common Mistakes
Reporting deposits as income when received
Refundable deposits are NOT income until forfeited or applied. Recording them as Year 1 income overstates your tax liability.
Forgetting to report forfeited deposits
When you keep a deposit for damages and don't report it as income, you're understating income — even if you offset it with repair deductions.
Not maintaining separate deposit accounts
Over 20 states require deposits in separate accounts. Commingling can mean forfeiture of your right to keep the deposit AND penalties.
Missing state interest payments
In states that require interest, failing to pay it can result in penalties of 2-3x the deposit amount.
Calling non-refundable fees "deposits"
Non-refundable move-in fees, pet fees, and cleaning fees are income when received — regardless of what you call them on the lease.
7. How SheltrIQ Handles Deposits
SheltrIQ properly accounts for security deposits as liabilities and automatically converts them to income when the right events occur:
Liability Tracking
Deposits are held as liabilities per tenant, per property. Never incorrectly reported as income until disposition.
Move-Out Workflow
When a tenant moves out, record damages and SheltrIQ auto-generates the income entry and offsetting repair expense.
State Compliance
Tracks interest requirements by state and calculates interest owed to tenants. Alerts you before deadlines.
Return Timeline Alerts
Get reminders for state-specific deposit return deadlines (14-60 days depending on state) to avoid penalties.
