Chapter 2 - Assessment Operations

Introduction

This  chapter is intended to illustrate the general workflow of the assessor’s office, and provide an overview of the duties that the assessor’s staff must accomplish on an annual basis. The first section of this chapter, entitled Nondate-Specific Statutory Duties, reflects tasks that must be accomplished daily or intermittently throughout the year. The remainder of this chapter is devoted to a monthly breakdown of tasks associated with statutory deadlines and recommended nondate-specific statutory tasks. Detailed procedures for accomplishing many duties are shown in Chapter 3, Specific Assessment Procedures

Areas of responsibility were divided among the following three teams:

  • Management Team: Assessor and top-level supervisors.
  • Administration Team: Staff assigned to perform administrative duties such as transferring ownership, mapping, certifying values, completing the abstract, maintaining the assessment roll, etc.
  • Appraisal Team: Staff assigned to perform real and personal property appraisal duties such as data gathering, appraising, data analysis, and building appraisal models, as well as supporting the values for protest and appeal hearings.

The procedures detailed in this chapter are based on the standard protest and appeal period, and should be reviewed and modified as necessary for each office depending upon the county’s parcel count, staff size, computer system and mapping capabilities, geographic location, etc.

Nondate-Specific Statutory Duties

Many duties must be accomplished before statutory deadlines or requirements can be met. This section deals with duties that are not tied to a specific deadline, but must be completed at various times throughout the year.

Management Team Tasks

  • Monitor completion of duties detailed for the Administration and Appraisal Teams, review status of each and reassign or redefine priorities as necessary.
  • Manage personnel issues.
  • Review status of budget regularly.

Administration Team Tasks

  • Process recorded title conveyance documents. Copies of conveyance documents that transfer commercial and industrial property should be routed to the individual(s) responsible for personal property records. (Refer to Title Conveyance in Chapter 3, Specific Assessment Procedures.)
  • Sales Confirmation:

    Review Real Property Transfer Declarations (TD-1000s) filed with deeds bearing a documentary fee and Manufactured Home Transfer Declarations (MHTD) filed with title applications.

    Send penalty notifications to grantees of deeds filed with incomplete or missing TD-1000s.

    Send penalty notifications to buyers of titled manufactured homes who have not submitted or have not completed MHTDs.

    Enter sales information from TD-1000s and MHTDs into sales database.

    Code sales with the appropriate valid or invalid sales code. (Refer to ARL Volume 3, REAL PROPERTY VALUATION MANUAL, Chapter 3, Sales Confirmation and Stratification.)

    Enter the appropriate invalid sales codes for deeds that are exempt from the documentary fee. (Refer to ARL Volume 3, REAL PROPERTY VALUATION MANUAL, Chapter 3, Sales Confirmation and Stratification.)

  • Process annexations, disconnections, inclusions and exclusions. (Refer to Boundary Changes for Taxing Entity in Chapter 3, Specific Assessment Procedures.)
  • Process subdivision, re-subdivision, townhome, condominium, and planned unit development plats. (Refer to Processing Plats, Chapter 3, Specific Assessment Procedures.)

  • Track and code changes when property goes from taxable to exempt or from exempt to taxable.
  • Process real property value prorations for:

    Changes in taxable status
    Movement of titled manufactured homes into or out of the state
    Destruction of improvements
    (Refer to Chapter 4, Assessment Math.)

  • Process Special Notices of Valuation for omitted property, titled manufactured homes moving into the county from out of state, and property that changed taxable status due to a forfeiture or revocation of tax exempt status or termination of a lease by the state, a political subdivision, or a state supported institution of higher education. (Refer to Circumstances Requiring a Special NOV and Procedures for Issuing a Special NOV in Chapter 3, Specific Assessment Procedures.)

    NOTE: When exempt property is sold, the tax exempt status is revoked upon deed recordation. For example, if exempt property owned by the ABC Church is deeded to the XYZ Church, the tax exempt status of the property is lost until such time as the XYZ Church applies for exemption, even if the XYZ Church has other property in the county that is exempt. The Division recommends sending a blank application for exemption along with the Special Notice of Valuation to the new owner. A copy of the deed should be sent to the Division’s Exemption section.

  • All fees collected by the assessor’s office shall be deposited with the treasurer’s office each month, § 30-1-112(1), C.R.S. Possible sources of revenue include personal property filing extension fees, § 39-5-116(1), C.R.S., or copy fees § 24-72-205(5), C.R.S. A full, true, and accurate accounting of the fees collected shall be entered into a ledger book each day, § 30-1-113, C.R.S. Any assessor who fails to make monthly deposits and/or maintain accurate records may be found guilty of a misdemeanor, and if convicted, may be removed from office, § 30-1-117, C.R.S.

  • Track and process leases and rental agreements submitted by the state, a political subdivision, or a state-supported institution of higher education that create an exemption under § 39-3-124(1)(b), C.R.S. (Refer to Real Property Leased to the State or Political Subdivision in Chapter 10, Exemptions.) The lessee is required to file a copy of the lease or rental agreement with the assessor’s office. The assessor must send a notice to the landlord acknowledging receipt of the lease or rental agreement. The notice must identify the property, the property address, and the parties to the lease or rental agreement, § 39-3-124(1)(b), C.R.S.

Assessment Date/Tax Lien Attaches

Property is assessed according to its taxable status, use, and condition on the assessment date. The tax lien attaches, and all property (taxable and exempt) located in the county on January 1, is listed on the assessment roll for the current year.

Beginning of County Fiscal Year

Colorado counties’ fiscal years run from January 1 through December 31. In other words, the current year’s budgeted funds become available on January 1. However, if funds were committed to pay for items and services before December 31 of the previous year, but the items, services or bill(s) were not received until January of the following year, the bill(s) must be paid from the previous year’s budget.

The unexpended balance of the assessor’s budget as of December 31 does not accrue to the assessor’s budget for the following fiscal year. Any unexpended balances revert back to the county’s general fund and may be used to fund other county services.

Management Team Tasks

  • Ensure that funds committed in the previous fiscal year are expended by January 31.
  • Conduct current year performance evaluation plans for employees, review job descriptions and work plans, and update as necessary. If performance evaluations are conducted on employees’ anniversaries, prepare a schedule for the year.
  • Chart appraisal license expiration dates for employees to ensure timely renewal, and to aid in budgeting for continuing education and license renewal fees.
  • Chart National USPAP Update course completion dates, as the course is required every other year.
  • Compile all approved contracts from external service providers, including: printing and mailing vendors, software vendors, consultants, MLS subscriptions and other data providers.
  • Chart approved pay raise dates and leave accruals.
  • Complete certification of values forms (DLG57) for each entity. Mail certification of values forms to cities, counties, and special districts to the Division of Local Government by January 3, for 2024 only. Mail certification of values forms for school districts to the Department of Education by January 3, for 2024 only.

Calculate the Estimated Aggregate Value of Exempt Business Personal Property

Beginning with the 2022 tax year, assessors must calculate the aggregate value of exempt business personal property for the county and each local governmental entity. This total is calculated by multiplying the applicable baseline exemption amount by the growth factor published by the Property Tax Administrator.

Declaration Schedules Mailed

By statute, declaration schedules are to be mailed as soon after January 1 as possible. Each year, the Division of Property Taxation develops and disseminates the approved declaration schedule forms to be used by property owners to report taxable personal property, oil and gas production, and mine production. (Refer to ARL Volume 5, Personal Property Valuation Manual.)

Management Team Tasks

  • Monitor completion of tasks detailed for the Administration and Appraisal Teams, review the status of each task, and reassign or redefine priorities as necessary.

  • Determine the number of Vacant Land Questionnaires required, and order an adequate supply of the most current form. The questionnaire is developed by the Division, and can either be photocopied or produced by a printing company.
  • Prepare the questionnaires for mailing (print labels, fold, sort).

Tax Warrant

The assessor delivers the tax warrant to the treasurer no later than January 10. (Refer to Chapter 7, Abstract, Certification, and Tax Warrant.)

Management Team Tasks

  • Monitor completion of tasks detailed for the Administrative Team, review the status of each task, and reassign or redefine priorities as necessary.
  • Certify the tax warrant to the county treasurer. (Refer to Chapter 7, Abstract, Certification, and Tax Warrant.)

Management Team Tasks

  • Monitor completion of tasks detailed for the Administration and Appraisal Teams, review the status of each task, and reassign or redefine priorities as necessary.
  • Remit to the treasurer all fees collected to date, and an itemized statement of the fees. Reconcile the statement with the assessor’s collection register.
  • Update the county’s personal property audit plan as needed, and determine the current status of physical audit inspections. The State Board of Equalization, mandates an assessor-defined 12-month audit period. The county plan is reviewed by the auditor each year. (Refer to ARL Volume 5, Personal Property Valuation Manual, Chapter 5, Addendum 5-A, Audit Standards.)
  • Review the status of the physical inspection of real property in accordance with the county’s re-inspection cycle. (Refer to Chapter 8, Assessment Planning Guidelines.)
  • Any real property leased or rented for at least a year by the State of Colorado, a political subdivision, or a state-supported institution of higher education is subject to an exemption if the lease is submitted to the assessor by the aforementioned political subdivision. Review newly submitted leases and previously submitted leases to determine the current year’s exemptions.
  • Pursuant to § 39-2-109(1)(d), C.R.S., submit forms for Division approval. Once the forms are approved, order the appropriate quantity of each form.
  • Write media releases detailing appraiser’s activities and the need for market-based data to accurately value property in the county.
  • See Nondate-Specific Statutory Duties at the beginning of this chapter.

Administration Team Tasks

  • For the most recent version of the taxpayer information brochures, please contact the Division. 
  • Exempt Property Master Record:

    Review the Exempt Property Master Record sent to the assessor by the Division in January. This report lists properties that are exempt because they are used solely and exclusively for religious, strictly charitable, or private school purposes. Compare the Master Record to the county records to identify any inconsistencies. Inconsistencies should be reported to the Division’s Exemptions Section. Correct abstract codes as necessary.

    If title to property granted exemption by the Division is transferred to a new owner, place the property on the assessment roll in the name of the new owner effective as of the date of such transfer. Notify the Division and provide the names of the grantor and grantee, the legal description, the parcel identification number, and the date of the transfer. Notify the new owner that in order to claim exemption for the property, a new application for exemption must be filed, even if the new owner is affiliated with the previous owner. Because of the change in taxable status, a proration of value is necessary, and a Special Notice of Valuation must be mailed. (Refer to Chapter 4, Assessment Math; Chapter 3, Specific Assessment Procedures; and Chapter 9, Forms Standards.)

    (Refer to Exemptions Determined by the Administrator in Chapter 10, Exemptions.)

  • Severed minerals:

    Create new accounts or activate existing accounts for mineral interests that were severed from the surface estate or from an existing mineral estate during the previous year.

    Deactivate accounts for severed mineral interests which expired in the previous year (time reservations).

    Create new accounts or activate existing accounts for severed mineral interests that are no longer a part of a producing mineral interest.

    Deactivate accounts for severed mineral interests that are now a part of a producing mineral interest.

    (Refer to Severed MineralsAdministrative Procedures in Chapter 3, Specific Assessment Procedures.)

  • Change tax area codes for titled manufactured homes that moved within the county in the previous year.
  • Prorate values:

    Raise to full value the titled manufactured homes that moved into the county from out of state during the previous year.

    Remove prorated value of structures that were destroyed in the previous year, and confirm the correct land classification with appraiser.

    If the proration of value of the structure is due to a natural disaster, the value removed from the tax roll will need to be tracked in order to report the amounts to the treasurer for reimbursement from the state.

    Adjust value of real property that changed taxable status after January 1 of the previous year.

    NOTE: This task requires close collaboration with the appraisal team, especially if the property is changing from exempt to taxable. An inspection may need to be made to confirm inventory, use, and the corresponding value. This new value comes from the appraisal side, and if occurring in an intervening year, constitutes an unusual condition. The Notice of Value must accurately reflect the change in class and value from the prior year. (Refer to Prorating Values in Chapter 4, Assessment Math.)

  • Annexation orders:

    Process any annexation orders that were filed in the previous year. (Refer to Boundary Changes for Taxing Entity in Chapter 3, Specific Assessment Procedures.)

    Notify appropriate personnel of new tax areas.

    Verify proper coding of annexed properties on assessment records and computer tables.

  • Change abstract classification code on parcels that changed use after January 1 of the previous year, i.e., formerly vacant parcels that are now improved, formerly improved parcels that are now vacant, etc.
