Security Deposit Accounting: Taxable Now, Later, or Never?

The first security deposit I ever collected went into my checking account, where it quietly stopped being the tenant's money and started being my money, at least in my head. Then the lease ended, I owed it back, and I got to learn a lesson about spending money that was never mine.

The second thing I did differently, on my first place, was open a separate bank account just for security deposits. I'll be honest about where that idea came from: I read it in a Nolo landlord's legal guide and just did it. No mentor, no CPA, no horror story that forced my hand. And here's the part that matters: in the years since, that account has never once saved me. No dispute, no audit, no "prove where the money went" moment. It has been completely, boringly immaterial.

That's the point. The whole reason to hold deposit money correctly is so it never becomes a story.

Quick answer: a security deposit is not rental income when you collect it, as long as you genuinely plan to return it. It becomes income in the year you keep some or all of it, for damages, unpaid rent, or a broken lease. And if the "deposit" is really the tenant's last month's rent, it was never a deposit at all. It's advance rent, taxable the day you receive it.

Three outcomes. One of them happens every time. The trick is knowing which one you're in.

Is a security deposit rental income?

Not while you might have to give it back.

Per IRS Publication 527, you don't include a security deposit in income when you receive it if you plan to return it to the tenant at the end of the lease. While it's refundable, the deposit is a liability sitting on your books, not revenue. It's the tenant's money. You're the one holding it.

That one fact breaks the most common mistake I see: landlords count the deposit as income the day it lands, then count the refund as an expense when it leaves. Both halves are wrong. If you collect $1,500 you plan to return, nothing hits your income. If you return all $1,500 a year later, nothing hits your expenses. The deposit never touches your tax return at all.

That's the "never" in the title. It's the outcome most tenancies end in, and it's the easiest one to get right, as long as you didn't spend the money.

When does a security deposit become taxable?

The year you keep it. Not the year you collected it, and not the year you spent it on repairs. The year the decision gets made that some of it is yours.

Per IRS Topic 414, if you keep part or all of a security deposit because the tenant broke the lease by leaving early, include what you keep in income that year. Same when you keep it for damage the tenant caused. The tax event is the keeping.

Say a tenant's lease ends in June and you keep $400 of a $1,000 deposit for wall damage, returning $600. The $400 is rental income for that year. The $600 was never income. Same deposit, same year, two different treatments on one line item.

This is also where the separate account earns its keep. At any given time I'm holding about $5,000 in deposits across my units. That's $5,000 sitting in an account with my name on it that is not my money, not income, and not mine to spend. If it lived in my operating account, I'd be reconstructing which dollars were the deposit and which were rent, months later, from memory. I've done the second version. It's exactly as fun as it sounds.

What if the "deposit" is really last month's rent?

Then it was never a deposit, and the IRS doesn't care what your lease calls it.

Per Publication 527, if an amount called a security deposit is to be used as a final payment of rent, it's advance rent. Advance rent is income in the year you receive it, regardless of the period it covers and regardless of your accounting method.

This is the trap in "first, last, and security" move-in packages. Three checks at signing, three different tax treatments:

What you collected	What it actually is	When it's income
First month's rent	Rent	The year you receive it
Last month's rent	Advance rent	The year you receive it (up front, not when the last month arrives)
Security deposit	A liability, while refundable	Only in the year you keep some or all of it

Collect all three in November and two of them are income that November. The deposit is the only one that waits. Landlords get this wrong in both directions: some pay tax on the refundable deposit (over-reporting), and some let the last-month's-rent piece ride until the end of the lease (under-reporting). The label in the lease matters less than the substance, but the IRS will read the label, so make sure the lease says what the money actually is.

I withheld deposit money for repairs. Do I report it and deduct the repair?

This is the fork nobody explains, because the IRS gives you two legitimate paths and they don't wash out to the same bookkeeping.

Per Topic 414, when you keep deposit money for damages and your practice is to deduct the repair cost as an expense, you include the kept amount in income and deduct the repair separately. But to the extent the deposit reimburses you for those repair costs, you can skip both sides: don't count the kept amount as income, and don't deduct the repair.

Two doors:

• Report both sides. Keep $400 for damage, spend $400 fixing it. Line 3 picks up $400 of income, the repairs line picks up $400 of expense. Net effect on your taxable income: zero.
• Report neither side. Keep $400 for damage, spend $400 fixing it. No income, no deduction. Net effect: also zero.

The tax bill is identical either way. What's not identical is the paper trail, and your ability to answer "where did this $400 come from" two years from now. My preference is the first path, because the income and the expense each get their own record instead of vanishing into a wash I have to re-explain to my accountant. But it's a practice choice, not a loophole, and it belongs in the "ask your CPA which way your books run" pile. Which is most of what a CPA is for: not filling in the grid, but making the judgment calls the form can't make for you.

Where do security deposits go on Schedule E?

Nowhere, while they're refundable. That's the point.

Refundable deposits never appear on the form. When you keep part of one, the kept amount lands in rental income on line 3 of Schedule E, in the year you kept it, right alongside the month's rent. Per the Schedule E instructions, line 3 is simply rents received, which is where forfeited deposit money ends up. The full breakdown of what else belongs there (late fees, pet rent, the prorated first month at a turnover) is in Schedule E for Rental Income: Line by Line.

One related line item that does show up, and surprises people: interest. Some states require landlords to hold deposits in interest-bearing accounts and pay the tenant the interest. That part is state landlord-tenant law, not federal tax law, and it varies enough that you should check your own state's rules rather than trust any blog post, including this one. If you do owe the tenant interest, it doesn't change the deposit's tax treatment; the refundable principal is still a liability.

How do you keep deposit money straight all year?

The same way you keep every other rental number straight: decide what the money is the moment it moves, not in April.

My setup on the first place was two habits, both borrowed straight from the Nolo guide. Every deposit went into its own account the day it arrived, so the money physically could not get spent. And every deposit got logged as what it was: deposit, not income, this property, this tenant, this amount. When the tenant moved out, the log already knew what I'd collected, so the return or the withholding was arithmetic, not archaeology.

The honest postscript: that account has never once bailed me out. No dispute, no audit, no moment where I had to prove a thing. And I'm glad. Deposit money done right is invisible, which is exactly what you want from money that was never yours. The version of this that goes wrong is the one you find out about later, in a disagreement or on a tax form, when the reconstruction is the punishment.

That's the whole discipline. A deposit is a promise with a date on it, and the recordkeeping question is just "can you prove, per tenant, what you're holding and what became of it?" If you can answer that off a log instead of off your bank statements, tax time stops caring about deposits entirely.

It's also why Doortrackr treats a forfeited deposit as its own income category. The day you decide to keep $400, you log it as income in about ten seconds, tied to the property, with the note about what it covered. At tax time it's already on the right line of the Schedule E report instead of hiding in a bank memo from June. Your accountant will love you, mostly because "I kept part of a deposit and here's the record" is a much better conversation than "I think I kept part of a deposit?"

However you track it, the rule is the same as it is for every receipt: capture what the money was for while you still remember. Future you will thank current you.

Frequently asked questions

Is a security deposit considered taxable income?

Not when you receive it, if you plan to return it. Per IRS Publication 527, a refundable security deposit is excluded from income. It becomes taxable only in the year you keep part or all of it.

Do I report a security deposit on Schedule E?

Only the part you keep. A refunded deposit never appears on Schedule E. An amount you keep for damages or unpaid rent goes on line 3 as rental income for that year.

Is last month's rent collected up front a security deposit?

No. Money designated as the final month's rent is advance rent, and per Publication 527 advance rent is taxable in the year you receive it, not the year it applies to.

If I keep a deposit for damages, do I also deduct the repair?

If your practice is to deduct repair expenses, include the kept amount in income and deduct the repair. Alternatively, per IRS Topic 414, to the extent the deposit reimburses the repairs, you can leave both sides off. Either way the net is zero; pick a practice with your CPA and stay consistent.

What if I keep the deposit because the tenant broke the lease early?

That's income in the year you keep it, the same as keeping it for damages. Topic 414 is explicit: amounts kept because the tenant didn't live up to the lease go into income that year.

Does the deposit count as income if it's in a separate account?

No, and the account doesn't decide anything. Tax treatment follows the refund obligation, not the bank location. A separate account is a discipline tool: it keeps you from spending money that was never yours and makes the eventual return or forfeiture easy to document.
