Is a kept security deposit taxable income? When it hits your Schedule E

Collecting a security deposit does not create taxable income. The IRS treats money you hold with the intent of returning it as money that is not yours yet, so a $2,000 deposit can sit in your account for five years without ever touching a tax return. Most landlords know that half of the rule.

The half that trips people up is move-out. The moment you withhold part of that deposit for unpaid rent or damage, the withheld portion becomes rental income, reportable in that year, on the same Schedule E line as your rent. And the repair you paid for with it becomes a deductible expense in the year you pay it. Both entries have to land, in the right year, or your return is wrong in one direction or the other. Here is how the pieces fit, with a filled-in example.

The rule: taxed when kept, not when collected

IRS Publication 527 states the rule in two sentences. Do not include a security deposit in your income when you receive it if you plan to return it to your tenant at the end of the lease. But if you keep part or all of it during any year because your tenant does not live up to the terms of the lease, include the amount you keep in your income for that year.

Two consequences follow directly. First, a deposit held across December 31 is invisible to that year's taxes; holding is not a taxable event, however long it lasts. Second, the income lands in the year of the forfeiture, not the year of the original payment. A deposit collected in 2022 and kept in 2026 is 2026 income.

There is one carve-out worth knowing before it bites. If the lease designates the deposit, or part of it, as the last month's rent, the IRS calls that amount advance rent, and advance rent is taxable in the year you receive it. Labeling money “deposit” does not change what it is. What the lease says it covers does.

Three endings, three treatments

Every deposit resolves in one of three ways, and each has a different tax answer.

• Returned in full. Nothing is income, nothing is deductible, and the deposit never appears on your return. The whole transaction is tax-neutral from collection to refund.
• Partially kept. The kept portion is rental income in the year you keep it; the returned portion remains a non-event. Withhold $1,400 of a $2,000 deposit and exactly $1,400 enters income. The $600 refund never does.
• Fully forfeited. The entire deposit is income that year, even when most of it covers rent you never received. On a cash-basis return, rent you billed but never collected was never income, so the kept deposit standing in for it is the first time that money gets taxed.

What you may withhold in the first place, the deadline for the itemized statement, and the documentation that survives a challenge are separate questions from the tax treatment. The security deposit guide covers deductions, deadlines, and returns, and the wear-and-tear line decides what a defensible withholding even is. Tax law takes your forfeiture as it finds it: if you kept the money, it is income, whether or not a judge would have let you keep it.

A filled-in Schedule E example

Say you rent a unit for $1,800 a month and hold a $2,000 deposit. The tenant short-pays October by $600, then moves out October 31 leaving two damaged doors and a bedroom wall that needs repainting beyond ordinary scuffing. You document the condition, pay a contractor $800 ($550 for the repaint, $250 for the doors), and send an itemized statement withholding $1,400: $600 for the rent shortfall and $800 for the repairs. A check for the remaining $600 goes back with the letter.

On Schedule E for that year, line 3, rents received, takes both the rent and the kept deposit:

Line 3 = rent collected + deposit kept = $17,400 + $1,400 = $18,800

The $17,400 is nine full payments of $1,800 plus the $1,200 partial in October. There is no separate line for forfeited deposits; the kept $1,400 rides along as ordinary rents received. Line 14, repairs, then picks up the $800 you paid the contractor. The net effect on taxable income is $1,400 in and $800 out, a $600 increase, which is exactly the rent shortfall you recovered. The forfeiture did not create new tax. It made you whole, and the return reflects that. For the rest of the form at the same altitude, the line-by-line Schedule E guide walks every entry.

The repair side: where the offset lands

The deduction is what keeps a kept deposit from becoming a tax problem, so classify it carefully. Repainting, patching drywall, rehanging a door, cleaning: these are repairs, deductible in full on line 14 in the year you pay them. A full replacement is different. New carpet throughout the unit, or a replaced appliance, is generally an improvement, capitalized and depreciated rather than deducted, even when a tenant's damage forced the decision. The repairs versus improvements guide classifies 20 common expenses, and the depreciation calculator shows what the multi-year recovery looks like in dollars.

Two details soften this for small landlords. The de minimis safe harbor lets you elect to expense items costing $2,500 or less per invoice, which covers most appliance swaps and many flooring jobs. And note the asymmetry on the rent side of the withholding: the $600 you kept for unpaid rent has no offsetting deduction at all, because you spent nothing to earn it. Income with no deduction attached is the part of a forfeiture that actually raises your tax bill.

Timing traps

• December move-out, January decision. The income belongs to the year you keep the money. A tenant who leaves December 28 while you finish the walk-through and itemization in January pushes the income into the new year. Record the dates; they decide the tax year.
• Last month's rent in deposit clothing. A lease that applies the deposit to the final month makes that amount advance rent, taxable on receipt, possibly years before move-out. If you have been treating it as a held deposit, the income was due earlier than you think.
• Refunds after a dispute. If you keep $1,400, report it, and later return $500 to settle a claim, the repayment is generally deductible in the year you pay it back rather than a rewrite of the earlier return. Keep the settlement paperwork with the deposit file.
• State interest and separate accounts. Some states require deposits to sit in a dedicated account, sometimes earning interest that belongs to the tenant. That interest is not your income, and the holding rules vary widely, so read your state's statute and the escrow and commingling guide before assuming anything about the account.

Getting it into your records

The bookkeeping problem with deposits is that one story spans years and lives in two halves of your books. The deposit arrives in one tax year as a liability, not income. The forfeiture happens in another year as income. The repair hits expenses that same year, unless it became an improvement on a depreciation schedule. I close my own books on the 5th of each month, and deposit forfeitures are the entries I check twice, because everything else in a rental ledger repeats monthly and this one never does.

So at move-out, record three things while the file is still open: the kept portion as rent income dated the day you withheld it, the contractor invoice as a repair (or an improvement), and the itemized statement attached as evidence. I built rents.ai because my spreadsheet kept dropping exactly this kind of one-off thread. It tracks each deposit from held through returned, partially returned, or forfeited, with itemized deduction lines behind the math, and once you record the kept portion as income and the repaint as a repair, its per-property Schedule E rollup places each on the lines described above. It will not classify repair versus improvement for you, and its tax view is an estimate to hand your CPA, not something it files. A deposit return letter that matches those entries to the dollar closes the loop with the tenant. One forfeiture, three entries, one year: that is the whole discipline.
