How to bookkeep a security deposit from a tenant

When you receive a security deposit from a tenant, it is important to bookkeep it as a liability, not income. This money still belongs to the tenant until certain conditions are met, such as move-out and damage assessment.

Understanding security deposits as a liability

A security deposit is money a tenant gives you to hold against potential damages or unpaid rent. It is not your money to keep or spend until the tenant moves out and you assess the property. Therefore, in accounting terms, it is a liability, specifically a 'current liability' on your balance sheet.

This means you owe that money back to the tenant, either in full or in part, at the end of his or her tenancy. Treating it as income prematurely would misrepresent your financial position and could lead to issues with your bookkeeping and potential tax implications. This is not tax advice; consult with a tax professional.

Setting up a separate bank account for deposits

Many states and municipalities have specific legal requirements regarding how security deposits must be held. Often, this includes keeping them in a separate bank account, sometimes an interest-bearing escrow account, distinct from your operating funds. Even if not legally required, it is a best practice for clarity and to prevent commingling funds.

A separate account makes it clear that these funds are not available for your regular business expenses. It simplifies tracking and ensures the money is readily available for refunding to the tenant when the time comes. This separation protects both you and your tenant.

Recording the initial receipt of the deposit

When you receive the security deposit, you will make a journal entry to reflect this. You would typically debit your 'Cash' or 'Bank' account (specifically, the separate security deposit account if you have one) to increase the asset. Then, you would credit a 'Security Deposit Liability' account to increase the liability.

For example, if you receive a 1,000 security deposit, your entry would be: Debit Cash (or Security Deposit Bank Account) 1,000; Credit Security Deposit Liability 1,000. This shows the cash came in, but you now have an obligation to return it.

Handling deductions and refunds at move-out

At the end of the tenancy, after the tenant moves out and you complete your property inspection, you will determine any deductions for damages beyond normal wear and tear or unpaid rent. Document these deductions thoroughly with photos, receipts, and a detailed breakdown.

If you deduct from the deposit, you will debit the 'Security Deposit Liability' account to reduce the liability. You will then credit the appropriate income accounts, such as 'Repair Income' or 'Rental Income,' for the amounts withheld. The remaining balance, if any, is then refunded to the tenant. If the entire deposit is refunded, you simply debit 'Security Deposit Liability' and credit 'Cash'.

Accounting for interest on security deposits (if applicable)

Some jurisdictions require landlords to pay interest on security deposits. If this applies to you, the interest earned on the separate security deposit account is typically considered an expense to you, as it belongs to the tenant. You would accrue this interest as an additional liability.

When you pay out the interest to the tenant, or apply it to his or her refund, you would debit the 'Security Deposit Liability' account and credit 'Cash' or 'Interest Expense.' Ensure you comply with all local laws regarding interest on deposits. This is not financial advice; consult with a local professional.

Annual reconciliation of deposit accounts

It is good practice to reconcile your 'Security Deposit Liability' account with the actual balances in your separate security deposit bank account periodically, at least annually. This ensures that the amounts match and that all deposits are accounted for correctly.

Reconciliation helps catch any discrepancies, ensures compliance, and provides an accurate snapshot of your financial obligations. This systematic check maintains the integrity of your bookkeeping records.

Impact on tax reporting

Since security deposits are liabilities, they are generally not considered taxable income when initially received. Only the portion of the deposit that you legitimately withhold for damages or unpaid rent at the end of the tenancy becomes taxable income in the year it is applied. Refunds are not expenses, they are a reduction of a liability.

Keeping clear, separate records for security deposits makes tax reporting much simpler and helps avoid potential audit issues. Always remember that this information is for bookkeeping purposes and does not constitute tax advice; please consult a qualified tax professional for specific tax guidance.

Questions people ask

Can I use a tenant's security deposit for repairs during the tenancy?

Generally, no. Security deposits are typically held until the tenant moves out to cover damages beyond normal wear and tear or unpaid rent at the end of the lease. Using it mid-tenancy is often against lease terms and local laws.

Do I need a separate bank account for every tenant's deposit?

Most jurisdictions that require separate accounts allow you to commingle all tenants' security deposits into one dedicated escrow or trust account, as long as detailed individual records are kept for each tenant.

What if the deposit isn't enough to cover damages?

If the damages exceed the security deposit, you can pursue the tenant for the remaining balance. This process would involve sending an itemized bill for the additional costs and potentially taking legal action, depending on your jurisdiction.

How long do I have to return a security deposit?

The timeframe for returning a security deposit varies by state and local laws, but it is typically between 14 and 60 days after the tenant vacates the property. Always check your local landlord-tenant laws for specific requirements.
