Which security deposit interest and separate account rules should a landlord check before drafting a statement?

The account rules decide what you can even say you hold

In many states the security deposit is not really your money while the tenant lives there. It is the tenant's money that you are holding, and the law often tells you where to hold it: a separate account, sometimes described as a trust or escrow account, kept apart from the operating account you pay the mortgage and the plumber from. Mixing deposits in with rent income is called commingling, and in the states that ban it the consequence is not about accounting neatness. It can affect what you are allowed to keep at the end of the tenancy. Related: What deductions can a landlord legally take from a tenant security deposit?

Practically, that means the account question comes before the deduction question. If you are a small landlord with one or two units and every dollar lands in the same checking account, the fix is cheap and takes an afternoon at the bank. Open a second account, move the deposits into it, and never pay a bill out of it. Do that now rather than at move-out, because the paper trail is what makes the story credible later. A statement that says a deposit was held properly is far easier to defend when the bank record shows it sitting untouched.

How deposit interest usually works, and who ends up owing it

Interest on deposits is a patchwork. Some states require it everywhere, some leave it to city ordinances, some tie it to how many units you own or how long the tenancy lasted, and plenty do not require it at all. Where it applies, the rate is normally set by statute or published each year by a state or city agency rather than chosen by the landlord, and it typically starts accruing from the month the deposit was received. Do not guess at a rate. Look up the figure that applied during the years you actually held the money.

Timing matters as much as the rate. In some places interest is paid out annually, either as a check or as a rent credit, and in others it simply accumulates until move-out and gets added to whatever you refund. Either way, unpaid interest does not disappear because a tenancy ended. If you bought a building and the previous owner never paid it, the obligation can follow the deposit to you, which is one more reason to ask for the full deposit and interest history in writing whenever a property changes hands.

Disclosures you may owe long before anyone moves out

Several states require a landlord to tell the tenant where the deposit is being held, sometimes including the name and address of the institution, and often within a short window after receiving the money. Others require a written receipt at the start of the tenancy. These obligations are easy to forget because nothing goes wrong at the time, and easy to regret because a missed disclosure tends to surface at exactly the moment a tenant is already unhappy about a deduction.

If you are behind on a disclosure, sending it late is generally better than never sending it, and it is worth asking a local attorney what curing it looks like where you rent. Going forward, attach the disclosure to the lease packet so it cannot be skipped. The version we see work best is one short paragraph at signing that names the institution, states whether interest accrues, and gets initialed right next to the deposit amount. That paragraph removes an entire category of argument two years before it would have happened. Related: Why should landlords attach evidence to every security deposit deduction they claim?

Putting account and interest facts on the statement itself

The statement should open with plain arithmetic, not with deductions. Start with the deposit received and the date you received it, add any interest owed through the move-out date, and only then list what you are withholding. Presenting it in that order shows the tenant you tracked their money as an obligation rather than as revenue, and it lets the final refund number reconcile without anyone reverse engineering it from a pile of charges.

Keep the supporting detail short but real. One line for where the deposit was held, one line showing the interest calculation with the rate and the period used, and a closing line with the refund amount and how it is being sent will usually cover it. If interest is not required where your property sits, say nothing rather than printing a line that reads zero, which mostly invites questions. Every figure on that page should be one you could back up with a bank record if someone asked.
