Why You Need a Quarterly Contribution and Wage Report
All Denver employers are legally required to file a Quarterly Contribution and Wage Report with the Colorado Department of Labor and Employment (CDLE) to comply with the Colorado Employment Security Act (C.R.S. Title 8, Articles 70-82). This report is the primary mechanism for the state to calculate your unemployment insurance (UI) tax liability, which is based on the total taxable wages you pay to employees each quarter. Failure to file, even if you have no wages to report for a given period, is a violation of your employer registration and can trigger an immediate audit. The CDLE uses this data to determine your business's experience rating, which directly impacts your future UI tax rate.
Not filing or filing late carries significant financial and operational penalties. Based on ApronPrep's analysis of enforcement actions, the most common consequences include:
- Monetary penalties: The CDLE imposes penalty assessments for late filing and/or late payment, which accrue on top of the owed contributions. Interest is charged on all unpaid amounts from the original due date.
- Increased audit risk: Late or missing reports flag your account for a higher probability of a full wage audit, requiring you to produce years of payroll records.
- Business operation impacts: A history of non-compliance can affect your standing with lenders or landlords during compliance checks, and in cases of suspected fraud, the state can pursue liens or other collection actions that jeopardize your business license.
Legal code: State unemployment insurance act, employer registration requirements
Recent update: As of 2026, the Colorado Department of Labor and Employment now mandates that all new employers must file their initial Quarterly Contribution and Wage Report electronically through the state's MyUI+ Employer portal, phasing out paper submissions for first-time filers.
Who Needs a Quarterly Contribution and Wage Report?

|---|---|---|
| Restaurant (Full-Service) | Required | Required because it operates within Denver city limits and has employees, making it liable for Denver Occupational Privilege Tax, which is reported via this quarterly wage filing. |
| Bar / Nightclub | Required | Required as it employs staff within Denver and is subject to the city's Occupational Privilege Tax, mandated under Denver Revised Municipal Code (DRMC) § 24-67. |
| Food Truck | Required | Required if the truck is based or regularly operates within Denver, employs staff, and thus incurs Denver Occupational Privilege Tax liability on wages paid within the city. |

1. Misreporting Employee Wages & Tips
Submitting gross wages without including employee-reported tips, or incorrectly categorizing overtime, is the most frequent error. The Denver Auditor's Office cross-references wage data with tip declarations from employee W-2s. A mismatch triggers a verification request, adding 2-3 weeks to your processing timeline. To avoid: Use the exact figures from your final quarterly payroll register, ensuring all cash and credit card tips reported by staff are included in the total 'wages subject to tax' field.
2. Using an Incorrect Reporting Quarter
Filing for Q1 (Jan-Mar) on a form labeled for Q4 (Oct-Dec) causes immediate rejection. The form's header and the online portal's filing period must match the calendar quarter for which you are reporting wages. Filing under the wrong quarter complicates your account history and can lead to penalties for a missed filing. To avoid: Triple-check the report year and quarter (e.g., '2026, Quarter 1') before submitting, and confirm your payroll dates fall entirely within that period.
3. Leaving the 'Denver Work Address' Field Blank or Incomplete
Entering only a P.O. Box or a headquarters address outside Denver when employees worked at a Denver location is a common oversight. The Denver Occupational Privilege Tax (OPT) is based on work location. An incomplete address prompts a manual review to determine tax jurisdiction, delaying processing by 1-2 weeks. To avoid: Provide the full physical street address, suite number, and ZIP code for the Denver location where your employees performed work, even if your business is headquartered elsewhere.

Gather Quarterly Payroll Records
Compile your restaurant's complete payroll data for the quarter: employee names, Social Security numbers, gross wages paid, and tax withholdings (federal, state, and unemployment insurance). You'll need pay stubs, payroll reports from your accounting software (QuickBooks, Gusto, ADP), and any separation notices for employees who left during the quarter. Most restaurants complete this in 1–2 hours if payroll records are organized; delayed data from late timekeeping entries is the #1 cause of submission delays.
Verify Colorado Unemployment Insurance Account Number
Confirm your Colorado Department of Labor and Employment (CDLE) Unemployment Insurance account number — this is required on the wage report and is different from your FEIN. You can find this on previous quarterly reports or by logging into the CDLE Online Services portal at https://www.colorado.gov/cdle. If this is your first report, contact the CDLE Employer Services line at (303) 318-8800 to confirm your account number was activated.
Complete the Quarterly Contribution and Wage Report (Form UI-3)
Fill out Colorado's UI-3 form with your company information, the reporting quarter, total wages paid, and employee-level wage details. Most employers now file electronically through the CDLE Online Services portal (https://www.colorado.gov/cdle/uiconnect), which has built-in validation to catch common errors like mismatched Social Security numbers or wage totals that don't reconcile. The form itself takes 30–45 minutes if your payroll data is organized; electronically filed reports typically process faster than paper submissions.

See All RequirementsThe timeline for submitting a quarterly contribution and wage report varies depending on your payroll complexity and data accuracy. Most restaurants complete the filing within 1–2 business days of the quarterly deadline (typically the last day of the month following each quarter), though processing by the Colorado Department of Labor and Employment may take an additional 5–10 business days for verification. To avoid penalties, file by the deadline posted on the department's website — contact the Colorado Department of Labor and Employment to confirm current deadlines for your filing quarter.
There are no government filing fees charged by the Colorado Department of Labor and Employment for submitting a quarterly contribution and wage report — the filing itself is required as part of your employer obligations at no charge. However, failure to file or filing late triggers penalties: the state assesses interest on unpaid contributions at the rate set by the department (typically 10% annually), plus potential civil penalties ranging from $25 to $500 per quarter depending on the reason for non-compliance, per Colorado Department of Labor and Employment enforcement guidelines. Verify current penalty amounts by contacting the department directly or checking their official website. Not legal advice.
A quarterly contribution and wage report is tied to your employer identification number (EIN) and business entity, not a physical location. If you're opening a second restaurant location or relocating, you'll need to file separate contribution and wage reports for each location if each has its own EIN — this requires registering with the Colorado Department of Labor and Employment under a new employer account. Before opening a new location, you should also complete your City Business License/Registration for Denver and your Colorado Employer Registration for Unemployment Insurance for the new entity. Contact the Colorado Department of Labor and Employment to confirm whether your existing quarterly filing can cover multiple locations under one EIN or if separate filings are required.
The quarterly contribution and wage report is not a 'renewal' in the traditional sense — it's a mandatory filing requirement that must be submitted every quarter (four times per year) as long as you have employees on payroll. Quarters end on March 31, June 30, September 30, and December 31, and most filings are due by the last day of the month following the quarter (e.g., April 30 for Q1). If you have no employees in a given quarter, you may still be required to file a zero-report — contact the Colorado Department of Labor and Employment to confirm whether null filings are required in your situation.
The quarterly contribution and wage report is not subject to a physical inspection — it is a document-based filing reviewed by the Colorado Department of Labor and Employment for accuracy and compliance. The department's compliance team verifies that wages reported match your payroll records, that employer and employee contributions are calculated correctly, and that all employee information (names, Social Security numbers, hours worked) is complete and matches other state filings like your Colorado Employer Withholding Tax Registration. If discrepancies are found, the department may request documentation (payroll registers, timesheets, tax records) or issue a compliance notice — contact the Colorado Department of Labor and Employment if you receive a notice or audit request to understand your next steps.
