Security deposits, advance rent, and what counts as income

A first year of letting a property has one tidy mistake waiting in it: everything that landed in the account gets treated as the year’s rent. It is not. Some of that money is not income at all yet, and some of it is income sooner than the calendar suggests.

Two rules do most of the work, and they point in opposite directions. A security deposit is generally not income while you intend to return it. Advance rent is income in the year you receive it, whatever period it covers. Money that looks identical arriving in the same week can fall on either side, and what decides it is what the money is for — not what the lease calls it.

A deposit is money you are holding

Publication 527 puts it plainly: do not include a security deposit in income when you receive it if you plan to return it to your tenant at the end of the lease.

Note what is doing the work in that sentence. It is the intention to return it — not the account it sits in, not the word “deposit” in the lease. While that intention holds, the money is a liability. You are holding someone else’s money against a condition that has not happened yet.

Landlord-tenant law in your state may have its own rules about deposits — separate accounts, interest, deadlines for returning them. That is a different body of law from the federal income question, and it does not decide the tax treatment. It does happen to point the same way, which is useful: a jurisdiction that makes you hold the money separately is telling you the same thing your books should say.

Advance rent is income when it arrives

Advance rent is any amount you receive before the period it covers, and Publication 527 is unusually firm about the timing: include it in rental income in the year you receive it, regardless of the period covered or the method of accounting you use.

That last clause is worth reading twice. Accrual accounting normally matches income to the period it belongs to. Here it does not. A landlord on the accrual method gets no more spreading than one on cash.

So last month’s rent collected up front is income now, even where the month it pays for is years away. Publication 527 works the example directly: sign a ten-year lease, receive the first year’s rent and the final year’s rent in the same year, and both amounts go into that first year’s income.

And the crossover that catches people: if an amount called a security deposit is to be used as the final payment of rent, it is advance rent — include it when you receive it. The label on the line of the lease does not decide it. What the money is contracted to do decides it.

The day a deposit turns into income

A deposit you intended to return stops being a liability the moment you keep it. Publication 527: if you keep part or all of a security deposit during any year because the tenant does not live up to the terms of the lease, include the amount you keep in income in that year.

That is the year you keep it, which is not always the year the tenancy ended. Where a deposit is still in dispute at the turn of the year, which year it falls in depends on the facts — a question worth putting to your preparer rather than settling in your own ledger.

Both of the common reasons for keeping a deposit produce income. Where they differ is on the expense side, and this is the half people net away:

• Applied to damage. The amount kept is income. The repair work is a separate item with its own treatment: an expense for repairing or maintaining the property may generally be deducted if you are not required to capitalize it, while work that is a betterment, a restoration, or an adaptation of the property to a new or different use must be capitalized and recovered over time instead. Two entries, not one net figure — and which of the two the repair is can genuinely go either way.
• Applied to unpaid rent. For a landlord on the cash method the amount kept is income, and no offsetting deduction turns up anywhere: Publication 527 says that because you have not included the uncollected rent in income, it is not deductible. The forfeited deposit is simply that rent, finally collected. On the accrual method the rent may already have gone into income, which changes where the entry belongs rather than whether it exists — one more reason to record what a kept deposit was applied to rather than the net.

The mirror of all this is quiet and worth stating: returning a deposit in full is not a deductible expense. It was never income, so giving it back is not a loss. It is a liability being settled, and it should leave your books the way it entered them.

Rent that does not arrive as money

Rent does not have to be a transfer to be income, and three situations come up often enough to plan for.

• Your tenant pays one of your expenses. Those payments are rental income. Because the amount goes into income, you can also deduct the expense where it is a deductible rental expense — so it is recorded twice, gross, rather than disappearing into a smaller rent figure.
• You receive property or services instead of rent. Include the fair market value in rental income. Where services are provided at an agreed or specified price, that price is the fair market value — but Publication 527 qualifies it with unless there is evidence to the contrary. An agreed price set well away from what the work is worth is not shelter, and a rent-for-labour arrangement is a place to get a professional view before the year closes rather than after.
• A tenant pays you to cancel the lease. That payment is rent, included in the year you receive it.

One more that changes which column money lands in entirely: under a lease that gives the tenant the right to buy, payments received are generally rental income — but if the tenant exercises that right, payments for the period after the date of sale are treated as part of the selling price. At that point the money stops being income and becomes part of the sale calculation, where basis is the whole story.

How this overstates a year

Here is a simplified, hypothetical illustration — the situation is made up to show the shape of the error, not to describe anyone’s return.

A tenant moves in on October 1 and, in the same week, pays the first month’s rent, the last month’s rent, and a security deposit equal to one month. Three identical amounts, one bank statement. On the rules above, the first month is rent, the last month is advance rent and therefore income now, and the deposit is not income at all while you intend to return it.

Total the bank statement and you have overstated the year by a month’s rent on a single unit. Do it across a few doors and it is a material figure on a document somebody hands a preparer as though it were settled. The error is not caught by anything downstream, because nothing downstream knows the deposit was a deposit.

Deposits held are a liability, not income you have earned. If the only record is the bank balance, the deposit and the rent are indistinguishable by the following April — and the money you owe back to a tenant looks exactly like money you earned.

The netting habit does the same damage from the other end. Offsetting a repair against a forfeited deposit shows a smaller income figure and a smaller expense figure; both move together, so nothing looks wrong, and neither number is the one the return asks for. Where you report the rental directly, rents received belong on Schedule E line 3, Rents received, with expenses reported on their own lines — the form is built to be told both halves. A rental held through a partnership or an S corporation, or one where you provide significant services to the occupant, reports somewhere else entirely, which is a question for your preparer before it is a bookkeeping one.

What to keep

None of the above is difficult while the facts are in front of you. All of it is guesswork eighteen months later. Per property, per year, the file wants:

• Rent received, with dates, kept apart from everything else that arrived
• Deposits held, as a running balance — date received, and date returned or kept, and when kept, what it was applied to, because damage and unpaid rent lead to different expense treatment
• Anything received as advance rent, marked as such, together with the period it covers — the period is not the year it belongs to, and in a few years nobody will remember which was which
• Non-cash rent: the fair market value you used, and how you arrived at it
• Expenses your tenant paid for you, with the underlying bill, since the amount is reported on both sides
• The lease itself, because what the money is for is a lease question before it is a tax question
• Separately from income altogether: improvements as against repairs, with dates and costs, plus the land value and the date the property was placed in service — property is placed in service when it is ready and available for its specific use, and land is not depreciated at all (Publication 527)

On a property marked as a rental, the Investor add-on carries part of this for you: rent received; deposits held tracked as their own thing rather than folded into income; operating expenses booked against Schedule E lines; and a downloadable file per tax year that lists every Schedule E line, including the ones that came to zero, so the gaps are visible instead of implied. Improvements are grouped by depreciation class with a subtotal each, and the property carries its land value and placed-in-service date.

The rest of the list it does not have a field for. An entry for money received takes an optional free-text note, which is where the period a payment of advance rent covers, or how you arrived at a fair market value, can go. An expense or an improvement takes an attached receipt rather than a note, so the bill behind an expense your tenant paid has somewhere to sit. The lease itself has no field at all. Those are yours to keep alongside.

What it does not do is depreciation. It totals what you entered and nothing else: there is no depreciation schedule and no depreciation figure anywhere — Schedule E line 18 is deliberately absent from every report. The depreciation class shown against an improvement is the conclusion you and your preparer reached, written down so it is not re-litigated every year. Recovery periods and the calculation itself live in Publication 946 and belong to the person preparing the return.

That division is the honest one. Whether a deposit was returned, when the advance rent arrived, and what a forfeited amount was applied to are facts only you can record, and only at the time. What they mean on a return is somebody else’s job — and a far easier job when the facts are already sorted.
