Colorado Security Deposit Refund Never Arrived: Deadlines, Reissue & the 7-Day Demand in 2026
A Colorado security-deposit statement is not the same as receiving the refund balance. Learn the 30/60-day deadline, 2026 payment rules, returned-payment provision and 7-day demand process.
The short answer
For conduct occurring on or after January 1, 2026, Colorado Revised Statutes section 38-12-103 generally requires a landlord to return the security deposit within 30 days after termination of the lease or surrender of the premises, whichever occurs last, unless the lease specifies a longer period that does not exceed 60 days. If the landlord retains part of the deposit, the written statement must list the exact reasons and the landlord must also deliver the difference between the deposit and the amount retained.
A statement showing that a refund is due and the refund payment itself are related but separate parts of that process. The 2026 version of the statute expressly treats failure to return the difference within the applicable deadline as wrongful withholding. Whether a particular landlord complied can still depend on the actual deadline, what payment method was used, where it was sent, whether it was returned to the landlord, and what happened after the tenant made a written demand.
Colorado's default deadline is 30 days, but the lease can extend it to 60
The 2026-effective version of section 38-12-103(1)(a) uses a 30-day default measured from the later of lease termination or surrender of the premises. A written lease can specify a longer security-deposit return period, but the statute caps that period at 60 days.
Do not calculate the deadline from the move-out date alone without checking the lease-end and surrender dates. Preserve the signed lease, key-return or possession evidence, and any written move-out confirmation so the controlling start date and any valid 60-day lease provision can be identified.
An itemized statement does not replace the required refund balance
When a landlord has actual cause to retain part of a deposit, the 2026 statute requires a written statement listing the exact reasons for the retention and requires the landlord to deliver the difference between the deposited amount and the amount retained. Section 38-12-103(2.5)(c) separately identifies failure to return that difference within the subsection (1) deadline as wrongful withholding.
That means a tenant should preserve both records: the accounting and evidence of the payment or nonpayment of the stated refund balance. If management says a check was mailed, ask for the check number, issue date, mailing address, mailing date, current status, and whether it was ever returned or negotiated. Conflicting mailing dates should also be kept in writing rather than resolved from memory.
How Colorado allows a security-deposit refund to be sent in 2026
Section 38-12-103(10), effective January 1, 2026, allows a landlord to send a required security-deposit refund by mailing the payment to the tenant's last-known address or, with the tenant's consent, by using a secured electronic transfer of funds.
If a tenant selected ACH or another electronic option on move-out paperwork, keep that consent and any confirmation. The statute permits a secured electronic transfer with the tenant's consent, but this guide does not assume that merely selecting an electronic option automatically eliminates the statutory mailing option or changes a separate lease term. The actual agreement and payment record still matter.
A refund payment returned to the landlord has a specific 15-day rule
Section 38-12-103(9), effective January 1, 2026, addresses a specific situation: a payment refunding all or part of the security deposit is returned to the landlord after it was sent to the tenant's last-known address. In that event, the landlord must hold the payment for at least one year after receiving it and disburse the payment to the tenant within 15 calendar days after the tenant requests it.
Do not stretch that rule beyond its text. If management says the payment was mailed but never reached the tenant and also says it was never returned to the landlord, subsection (9) may not describe that exact fact pattern. Document whether the payment was actually returned, lost, cancelled, stale-dated, or simply unaccounted for before relying on the 15-day provision.
What about a stop-payment or reissue fee?
The Colorado official sources reviewed for this guide do not cleanly state that a landlord may or may not charge a separate stop-payment or check-reissue fee when a security-deposit refund never reaches the tenant. Section 38-12-103 does limit the reasons for retaining security-deposit money and requires timely delivery of the refund balance, but that does not justify inventing a categorical answer about every bank or reissue fee.
Ask the landlord in writing to identify the lease provision and legal basis for the fee, whether the original payment was actually returned or merely not received, and documentation of any actual bank charge. Keep the fee question separate from the undisputed refund balance. A tenant should not assume the fee is automatically valid, and a landlord should not assume a bank charge automatically becomes a lawful security-deposit deduction.
The 7-day demand matters before a treble-damages action
Under the 2026-effective version of section 38-12-103(3), a tenant seeking to bring a court action for treble damages, reasonable attorney fees, and court costs must first notify the landlord of the demand for return of the security deposit and the intention to file legal proceedings at least seven days before filing. Subsection (3)(c) says the tenant may bring that action only if the landlord fails to return the entire security deposit or withheld portion within seven days after receiving the demand and notice.
Do not describe treble damages as an automatic payment simply because a deadline was missed or a check did not arrive. The statute defines wrongful withholding and allocates burdens in a court action, but the facts, the amount actually withheld, compliance with the demand prerequisite, and the court's application of the statute still matter.
Build a written timeline before disputing a missing refund
Keep the lease and security-deposit clause, move-out and surrender dates, forwarding-address notice, any ACH or electronic-transfer consent, the final itemized statement, the amount stated as refundable, the original deposit record, emails or portal messages about when payment was supposedly sent, any check number or image, proof that the check was not negotiated if available, and every response to a reissue request.
If sending a seven-day demand, preserve the signed or saved demand itself and reliable evidence showing when and how the landlord received it. A clean timeline lets the parties separate four different questions: the statutory deadline, the amount lawfully retained, what happened to the refund payment, and whether any proposed reissue fee has an independent basis.

Common questions
How long does a Colorado landlord have to return a security deposit in 2026?
For conduct on or after January 1, 2026, C.R.S. § 38-12-103 generally uses a 30-day deadline after the later of lease termination or surrender. The lease may specify a longer period, but not more than 60 days.
If the final statement says I am owed a refund, is the statement itself enough?
The statute requires the landlord to deliver the difference between the deposit and any amount lawfully retained. The 2026 version separately identifies failure to return that difference within the applicable deadline as wrongful withholding.
Can a Colorado security-deposit refund be sent electronically?
Yes. Effective January 1, 2026, subsection (10) permits a secured electronic transfer with the tenant's consent. Mailing the payment to the tenant's last-known address is also an authorized method.
What if a security-deposit refund check is returned to the landlord?
If the payment is returned to the landlord after being sent to the tenant's last-known address, subsection (9) requires the landlord to hold it for at least one year and disburse it within 15 calendar days after the tenant requests it.
Can a Colorado landlord charge a stop-payment or reissue fee for a missing deposit check?
The official sources reviewed here do not cleanly provide a categorical authorization or prohibition for a separate stop-payment or reissue fee in every missing-check situation. Ask for the lease and legal basis and documentation of the claimed cost, and keep that issue separate from the required refund balance.
Are treble damages automatic if a Colorado security deposit is late?
Do not treat treble damages as automatic. The 2026 statute requires a demand for return plus notice of intent to file at least seven days before suit, and the court action depends on wrongful retention and the facts of the case.
