Purpose of a Security Deposit

Idaho Stat. 6-321 states that security deposits are amounts given by a tenant to a landlord for any purpose other than the payment of rent. The purpose of a security deposit is to serve as a safety net for landlords if they suffer financial losses that may be caused by damages to the rental property, unpaid rent or other breaches of the lease agreement. A security deposit ensures that a landlord is compensated for losses and may also incentivizes tenants to adhere to their lease obligations in order to have their security deposit returned at the end of the lease term.

Allowable Security Deposit Charge in Idaho

Idaho Stat. 6 -321 doesn’t establish a limit on the amount of security deposit that a landlord can charge a tenant. There is no statute related to pet deposits or non-returnable fees. Landlords are also not required to provide tenants with a receipt for the security deposit.

Security Deposit Rules & Regulations for Landlords in Idaho

  • Interest Payment: Landlords are not required by law to hold the security deposit in an interest-bearing account, nor in escrow, but the name of the banking institution where it is being held should be included in the lease agreement.
  • Allowable Deductions From Security Deposit: Landlords are allowed to only make deductions for reasons that have been established in the lease agreement and cannot deduct for normal wear and tear.
  • Applying Security Deposit as Last Month’s Rent: A security deposit is not intended to be used as the tenant’s last month’s rent. The security deposit is not rent money and wouldn’t simply be used to cover tenants’ last month’s rent if they vacate without paying. It’s meant to cover damages/losses.
  • How to Get a Full Refund: At the end of the tenancy, a full security deposit can be returned to the tenant if there is no damage to the rental property, rent is paid in full and all charges in the rental agreement are covered.
  • New Property Owner’s Responsibility: If the property changes ownership during the period of a tenant’s rental agreement, the new owner becomes responsible for the security deposit and returning it to the tenant. It is also possible for the current landlord to refund the security deposit if the transaction occurs at the end of the tenancy.

Returning Security Deposits in Idaho

Prior to signing a lease agreement, landlords should clear up with tenants any potential issues surrounding security deposits, such as when they can get their security deposit back.


If any portion of the security deposit is being withheld by the landlord, a signed statement itemizing the amounts that is being withheld, the reason for the withholding and a detailed list of the charges made from the deposit should accompany the remaining security deposits (Idaho Stat. 6 -321).

  • Time Frame: Idaho landlords are required to return security deposits to tenants within 21 days if there is no fixed time written in the lease agreement, and in any case, 30 days after the tenant has surrendered the rental unit.

  • Failure to Return Security Deposit as Required: If a Idaho landlord fails to return the deposit and provide an itemized list of damages and the charges within the required time period, the tenant has the right to take legal action against the landlord to have the deposit returned.
  • Failure to Pay Interest: A landlord who willfully fails or refuses to pay the interest required and is found to have done so by a circuit court will be liable to the tenant for an amount equal to the amount of the security deposit, together with court costs and reasonable attorneys fees (765 ILCS 715/2).

“Normal Wear and Tear” vs. Damage in Idaho

  • Idaho Stat. 6 -321 defines “Normal wear and tear” as deterioration that occurs as a result of use for which the rental unit is intended and without negligence, carelessness, accident, or misuse or abuse of the premises or contents by the tenant or members of his household, or their invitees or guests.
    It can include minor issues, such as gently worn carpets, loose door handles, fading wall paint and flooring, stained bath fixtures, lightly scratched glass and dirty grout that occur naturally as a result of the tenant using the property as it’s designed to be used.
  • Damage” refers to destruction to the rental unit that occurs because of abuse or negligence by a tenant during the course of the tenancy and can affect usefulness, value, normal function of the rental unit. Pet damage (heavily stained and ripped carpet), broken tiles, hole in the wall, broken windows and missing fixtures are all examples of damage.

Security Deposits and Tax Filing in Idaho

A security deposit can either be held to cover losses suffered by the landlord or refunded to the tenant, all or in part. How security deposits are treated for tax purposes depends on whether or not a landlord retains or provide the tenant with a refund when the lease is terminated.

  • Accounting for Security Deposits : Security deposits are treated as either assets or liabilities when filing taxes. It is not automatically rental income when first received. Tenants shouldn’t deduct security deposits as expenses when filing their taxes and landlords shouldn’t declare them as income when in escrow intended to be returned to the tenant at the end of the tenancy. Security deposits are not income until they become as such.
  • Security Deposit Write-off : Usually, landlords cannot deduct security deposits when filing taxes as expenses before they are used for one purpose or another. If a landlord withholds part or all of the security deposit for unpaid rent, then that amount should be included as income for that year when filing taxes. Forfeited deposits should be declared as income on a landlord’s tax return. A deposit is taxable income only if and when a landlord has no obligation to refund the tenant.

  • Withhold security deposits for any financial losses, damage or other expenses
