Chapter 9 - Form Standards

#FFFFFF

Introduction

By law, the Property Tax Administrator must approve all personal property schedules, forms, and notices furnished or sent by assessors to owners of taxable property, the form of petitions for abatement or refund, the form of all field books, plat and block books, maps, and appraisal cards, and other forms and records used and maintained in the office of the assessor, §§ 39-2-109(1)(d) and (h), C.R.S.

This chapter includes information that provides the required content of many of the forms that are used in the assessor’s office. Additionally, form templates are provided on the Division's website under Forms Templates. The information in this chapter and the form templates are based on the statutory dates and deadlines used for the standard protest and appeal procedures. The statutory dates and deadlines may be changed to reflect the alternate protest procedure, or adjusted to dates that do not conflict with weekends or holidays. Refer to Addendum 9-A, Statutory and Adjusted Dates for Standard and Alternate Protest and Appeal Procedures.

Each county may develop forms that differ from the form templates in design or content (except Senior Citizen and Veteran With a Disability Property Tax Exemption applications and manufactured home forms). However, county-developed forms that differ in content must be submitted to the Division for review and approval. This centralized form approval system helps achieve statewide uniformity of the forms and ensures that the information requested of taxpayers and reported by assessors is consistent.

Form Approval Procedures

County-developed forms may be submitted to the Division for approval between January 1 and March 31. The form review process typically takes less than 10 business days. Following the procedures outlined below will expedite the approval process:

  1. Prior to developing a new form, review the form templates provided on the division website to ensure that the required content is incorporated into the county’s form. Any additional information that appears on the form must not conflict with or detract from the required content.
  2. Assign a number to the form that uniquely identifies the form. The form numbering system developed by the Division is shown in Addendum 9-B, Form Numbering System.
  3. The Division recommends submitting the form for approval prior to having it typeset or entered into the county’s computer program in an effort to reduce costs.
  4. Notification of form approval will typically be communicated within 10 working days.
  5. Any changes that must be made to the form prior to approval will typically be communicated within 10 working days.
  6. If changes are required, the revised form is submitted to the Division for a second review. (Steps four and five will continue until the form meets the required criteria.)

Availability of Forms

The forms referenced in this chapter are available on the Division's website. The availability of the forms that are in Microsoft Word format, or on the Division’s website, are shown below. Forms that are available in Microsoft Word format will be e-mailed to you upon request. The year in the templates are formatted as “20__” in order to provide greater flexibility in use. The assessor’s office will be required to fill in the appropriate year before making the form available to the public.

Notice of Valuation – Real Property

Specific Requirements

The sample Real Property Notice of Valuation illustrates the form content required by the Property Tax Administrator and § 39-5-121(1), C.R.S. While the majority of the data that must be inserted in each section of the form is self-explanatory, items that may require additional explanation are addressed below.

Date of Notice/Mailing Deadline: A Notice of Valuation (NOV) must be mailed annually to each owner of real property no later than May 1. Upon taxpayer’s request, the NOV may be sent electronically. During intervening years, the Real Property NOV may be mailed with the tax bill when the value of the property has not changed, § 39-5-121(1.2), C.R.S.

Property Classification: The property must be listed by its class or subclassification description, e.g., Single Family Residence, Offices, Warehouse/Storage, etc.

Reclassification of Agricultural Property: Subject to the availability of funds under the assessor's budget for such purpose, no later than May 1 of each year, the assessor shall inform each person whose property has been reclassified from agricultural land to any other classification of property of the reasons for such reclassification including, but not limited to, the basis for the determination that the actual use of the property has changed or that the classification of such property is erroneous, § 39-1-103(5)(c), C.R.S. The reasons for the reclassification may appear in the Property Classification section of the NOV.

Property Values: Property values must be stated in the form of actual values. Listing the assessed value on the NOV is prohibited by law. For agricultural property, land and improvements must be LISTED and valued separately. For all other property, the total property value must be listed, § 39-5-121(1)(a), C.R.S.

Commercial Property Approach to Value Statement: Any NOV sent to the owner of commercial property must include contact information for the relevant county assessor along with the following statement: "If you would like information about the approach used to value your property, please contact your county assessor."§ 39-5-121(4)(b), C.R.S.

Timely Objection Statement: Any notice of valuation required by subsections (1) and (1.5) of this section sent to the owner of any real property must include the following statement: "if a property owner does not timely object to their property's valuation by June 8 under section 39-5-122, C.R.S., they may file a request for an abatement under section 39-10-114, C.R.S., by contacting the county assessor.".

Spanish Language Requirements: On October 21, 1985, the State Board of Equalization issued an order requiring certain counties to print a Spanish language statement on their NOVs. A second order, issued July 10, 1986, modified the Spanish language statement. The orders were issued pursuant to an action filed against the state board in Denver District Court by a group of Conejos County taxpayers. One of the points argued by the group was that county taxpayers were denied their right of due process by receiving NOVs written solely in English when a majority of county residents speak Spanish. The parties stipulated, and the court remanded the matter back to the state board to issue orders consistent with the stipulation.

The Director of the Census Bureau determines which counties must comply with the minority language assistance provisions of Section 203 of the voting rights act of 1965, as amended in 1982, 42 US CONST. 1973 et seq. Based on the results of the 2015 American Community Survey, the following counties must comply: Costilla, Denver, Rio Grande, and Saguache. Refer to Addendum 9-C, Spanish Language Requirements, for the required Spanish language that must be included on the NOV.

Notice of Senior Citizen and Veteran with a Disability Property Tax Exemptions: Notice for the senior exemption must be included with the treasurer’s tax bill in January. If the notice for the veteran with a disability exemption is not also included in the treasurer’s tax bill in January, the assessor must include it with the assessor’s Real Property Notice of Valuation, or send it as a separate mailing, § 39-3-204, C.R.S. Refer to Addendum 9-D, Notice of Senior Citizen and Veteran with a Disability Property Tax Exemptions for required content.

Protest Form: A form that may be completed by the property owner to initiate a protest of the classification or valuation of the property must be included with the Real Property NOV. A Real Property Protest Form is available on the Division's website under Forms Templates.

Required Alternative Protest Period Criteria

Property owners who are protesting the value of rent producing commercial real property, in accordance with § 39-5-122(2), C.R.S., shall provide the county assessor’s office on or before July 15 the following information pursuant to § 39-5-122(2.5), C.R.S.:

  • Actual annual rental income for two full years including the base year for the relevant property tax year;
  • Tenant reimbursements for two full years including the base year for the relevant property tax year;
  • Itemized expenses for two full years including the base year for the relevant property tax year; and
  • Rent roll data as of the valuation date, including the name of any tenants, the address, unit, or suite number of the subject property, lease start and end dates, option terms, base rent, square footage leased, and vacant space for two years including the year of the valuation date and the prior year.

Counties using the alternative protest period shall provide information about this requirement on their NOVs in order to inform taxpayers in a timely fashion. Refer to Alternate Protest Period Real Property Notice of Valuation in this chapter for required content.

Required Reappraisal Year Criteria

Property Characteristics: An itemized listing of the land and improvements, as well as the property characteristics that are germane to value must be included, §§ 39-5-121(1)(b)(I) and (II), C.R.S. To satisfy the first requirement, assessors may choose to provide a count and a total square footage or acreage for each subclassification comprising the subject property. To satisfy the second requirement, the physical characteristics relied upon to determine the actual value of the property (characteristics “germane to value”) must be listed. Each assessor must determine the categories of data to be included to satisfy the requirements set forth in §§ 39-5-121(1)(b)(I) and (II), C.R.S.

Required Intervening Year Criteria

Increase in Value of Land or Improvement Greater than 75%: If the difference between the actual value of the land or improvement in the reappraisal year and the actual value of the land or improvement in the intervening year increases by more than 75%, the assessor shall mail together with the NOV an explanation for the increase in value, § 39-5-121(1)(a), C.R.S. Note that the explanation is required when either the land or the improvement value increases by more than 75% – not simply when the total actual value increases by more than 75%.

County Discretion

Data Gathering Period: In the last two sentences of the Valuation Information section shown on the reverse side of the NOV, the references to the 18-month data gathering period may be changed to reflect the data gathering period used by the county, e.g. a 24-month data gathering period.

Protest Form: In lieu of sending a separate Real Property Protest Form with the NOV, an abbreviated version of the protest form may be printed below the Protest Procedures section on the reverse side of the NOV. Refer to the Real Property Protest Form standards shown in this chapter.

If an abbreviated version of the protest form is incorporated into the Real Property NOV, the sentence following the dates, time and location of hearings should be changed to:

To assist you in the protest process, you may elect to complete and submit the Real Property Protest Form shown below.

Alternate Protest and Appeal Procedure: If the county is utilizing the alternate protest and appeal procedure set forth in § 39-5-122.7, C.R.S., the dates that appear on the NOV must be changed as shown in Addendum 9-A, Statutory and Adjusted Dates for Standard and Alternate Protest and Appeal Procedures.

Special Notices of Valuation

Assessors are allowed under statute to change property values after regular Notices of Valuation have been mailed, but only in the following circumstances:

  • Omission of property from the tax warrant
  • New construction added to assessment roll after May 1
  • Titled manufactured home moved into the county from out of state
  • Titled manufactured home not exempt as inventory
  • Forfeiture of exempt status of property
  • Revocation of exempt status by the Property Tax Administrator
  • Loss of exempt status due to transfer of property
  • Loss of exempt status because property is no longer leased by the state or political subdivision of the state
  • Under-reported oil and gas volume

If values are changed based on one of the reasons above, the taxpayer must be given due process to challenge the new value. The Division of Property Taxation recommends that the assessor send the taxpayer a Special Notice of Valuation that gives the taxpayer notice of the new value and the opportunity to challenge the value.

For a more detailed discussion of the circumstances under which a Special Notice of Valuation should be issued, as well as the procedures for issuing a Special Notice of Valuation, refer to Chapter 3, Specific Assessment Procedures, and to ARL Volume 3, REAL PROPERTY VALUATION MANUAL, Chapter 6, Valuation of Natural Resources.

Sections 39-5-125 and 39-10-101(2)(a), C.R.S., authorize retroactive assessments only against “omitted property” not against “omitted value.”

Section 39-8-102(1), C.R.S., authorizes the county board to correct any errors made by the assessor. Such errors should be brought to the attention of the county board of equalization. A sample memo from an assessor notifying the county board of an error in valuation is shown in Addendum 9-E, Memo to CBOE Requesting Change in Value or Classification. If the county board determines that an adjustment is warranted, the county board issues a resolution to effect the change and mails a notice to the property owner that explains the board’s decision and advises the property owner of his/her appeal rights. A sample notice from the county board of equalization to an owner whose property was valued in error is shown in Addendum 9-H, Sample Notice from CBOE to Property Owner Regarding Change in Value or Classification.

Section 39-10-101(2)(d), C.R.S., authorizes retroactive assessments of omitted property or production of mines and oil and gas leaseholds and lands.

Special Notice of Valuation – Real Property

Specific Requirements

The sample Real Property Special Notice of Valuation illustrates the form content required by the Property Tax Administrator and § 39-5-121(1), C.R.S. While the majority of the data that must be inserted in each section of the form is self-explanatory, items that may require additional explanation are addressed below.

Property Classification: The property must be listed by its class or subclassification description. For agricultural property, land and improvements must be listed and valued separately.

Property Values: Property values must be stated in the form of actual values. Listing the assessed value on the NOV is prohibited by law. For agricultural property, land and improvements must be listed and valued separately. For all other property, the total property value must be listed, § 39-5-121(1)(a), C.R.S.

Prior Actual Value: This section should be completed using the value that appeared on the last NOV that was issued for the property.

Actual Value for Tax Year _____: The appropriate tax year must be inserted.

Full Year: If the property is being assessed for the full year, the actual value should be listed in this section of the form.

Partial Year: If the property is being assessed for a portion of the year, the prorated value of the property should be listed in this section of the form.

Spanish Language Requirements: On October 21, 1985, the State Board of Equalization issued an order requiring certain counties to print a Spanish language statement on their NOVs. A second order, issued July 10, 1986, modified the Spanish language statement. The orders were issued pursuant to an action filed against the state board in Denver District Court by a group of Conejos County taxpayers. One of the points argued by the group was that county taxpayers were denied their right of due process by receiving NOVs written solely in English when a majority of county residents speak Spanish. The parties stipulated, and the court remanded the matter back to the state board to issue orders consistent with the stipulation.

The Director of the Census Bureau determines which counties must comply with the minority language assistance provisions of Section 203 of the voting rights act of 1965, as amended in 1982, 42 US CONST. 1973 et seq. Based on the results of the 2010 census, the following counties must comply: Costilla, Denver, and Rio Grande. Refer to 9-C, Spanish Language Requirements, for the required Spanish language that must be included on the Special NOV

Special Protest Form: A form that may be completed by the property owner to initiate a protest of the classification or valuation of the property must be included with each Special NOV. Refer to the Real Property Special Protest Form shown in this chapter.

Property Characteristics: An itemized listing of the land and improvements, as well as the property characteristics that are germane to value must be included, § 39-5-121(1)(b)(I) and (II), C.R.S. To satisfy the first requirement, assessors may choose to provide a count and a total square footage or acreage for each subclassification comprising the subject property. To satisfy the second requirement, the physical characteristics relied upon to determine the actual value of the property (characteristics “germane to value”) must be listed. Each assessor must determine the categories of data to be included to satisfy the requirements set forth in § 39-5-121(1)(b)(I) and (II), C.R.S.

Although this information is only required by law to appear on the Special NOV if the tax year at issue was a reappraisal year, the Division recommends supplying an itemized listing of the land and improvements, as well as the property characteristics that are germane to value on all Real Property Special NOVs.

Commercial Property Approach to Value Statement: Any NOV sent to the owner of commercial property must include contact information for the relevant county assessor along with the following statement: "if you would like information about the approach used to value your property, please contact your county assessor."§ 39-5-121(4)(b), C.R.S.

The value of the property will be entered on the tax warrant for the following reason(s):

  • The exempt status of the property was revoked by the Property Tax Administrator.
  • The property no longer qualifies for exemption due to transfer of ownership. If you think the property may qualify for exemption for religious purposes, private schools, or strictly charitable purposes, please contact the Division of Property Taxation at 303-864-7780 to apply for an exemption.
  • The property no longer qualifies for exemption as the lease or rental agreement with the state, political subdivision or state-supported institution of higher education has been vacated.

Data Gathering Period: The year of the 18-month data gathering period and the year of the five-year data gathering period applicable to the tax year at issue must be completed.

Intervening Year Criteria

Increase in Value of Land or Improvement Greater than 75%: If the tax year at issue was an intervening year and the difference between the actual value of the land or improvement in the reappraisal year and the actual value of the land or improvement in the intervening year increased by more than 75%, an explanation for the increase in value must be provided, § 39-5-121(1)(a), C.R.S. Note than the explanation is required when either the land or the improvement value increases by more than 75% - not simply when the total actual value increases by more than 75%.

County Discretion

Data Gathering Period: In the last two sentences of the Valuation Information section shown on the reverse side of the NOV, the references to the 18-month data gathering period may be changed to reflect the data gathering period used by the county, e.g. a 24-month data gathering period.

Spanish Language Requirements: On October 21, 1985, the State Board of Equalization issued an order requiring certain counties to print a Spanish language statement on their NOVs. A second order, issued July 10, 1986, modified the Spanish language statement. The orders were issued pursuant to an action filed against the state board in Denver District Court by a group of Conejos County taxpayers.

The parties stipulated, and the court remanded the matter back to the state board to issue orders consistent with the stipulation.

The Director of the Census Bureau determines which counties must comply with the minority language assistance provisions of Section 203 of the voting rights act of 1965, as amended in 1982, 42 US CONST. 1973 et seq. Based on the results of the 2010 census, the following counties must comply: Costilla, Denver, and Rio Grande. Refer to Addendum 9-C, Spanish Language Requirements, for the required Spanish language that must be included on the Special NOV.

Addendum 9-C, Spanish Language Requirements

On October 21, 1985, the State Board of Equalization issued an order requiring certain counties to print a Spanish language statement on their NOVs. A second order, issued July 10, 1986, modified the Spanish language statement. The orders were issued pursuant to an action filed against the state board in Denver District Court by a group of Conejos County taxpayers. One of the points argued by the group was that county taxpayers were denied their right of due process by receiving NOVs written solely in English when a majority of county residents speak Spanish. The parties stipulated, and the court remanded the matter back to the state board to issue orders consistent with the stipulation.
