... All statutory tax levies ... shall be so reduced as to prohibit the levying of
a greater amount of revenue than was levied in the preceding year plus five
and one-half percent (5.5%)...


The statutory "5.5%" Property Tax Revenue Limit, also known as the "Annual Levy Law" (Section 29-1-301, et seq., C.R.S.), applies to most statutory local governments that levy for property taxes. It does not apply to home-rule municipalities.


For subject governments, the "5.5%" limit restricts the amount of property tax revenue that may be collected each year. The local government's limit is calculated by using information found on the Certification of Valuation (CV) sent by the county assessor by August 25 of each year. A final CV may be sent by December 10th for valuation information that the assessor may have changed.


A worksheet is available to assist in calculating the statutory property tax revenue limitation, however, the Division of Local Government (DLG) also calculates the government's "5.5%" limit. This is done in September and again in December following the county assessors re-certification of valuation. Local governments should compare the 5.5% limit with the TABOR property tax limit to determine which one is the most restrictive property tax revenue limitation.

* Note: The 5.5% Property Tax Revenue Limit Calculations on the DLG53 do NOT take into account any other limits that may apply to your property tax revenue, such as statutory mill levy caps, voter-approved limitations, the TABOR property tax revenue limit, or the TABOR prohibition against increasing the mill levy without voter authorization.




The Division of Local Government calculates each "subject" local government's 5.5% Property Tax Limit Calculation (DLG 53) two times each year. In August a preliminary DLG53 calculation is done which corresponds to the "preliminary certification of value" for each local government which is completed by the county assessor. In December the assessors complete the "final certifications of value" and the Division then completes a second calculation utilizing those updated numbers.


Links to the calculations above are provided by tax entity name either in alphabetical order or by county. Tax entities that are located in multiple counties will have a second page detailing the values provided by each county assessor. These reports will update each day with any changes processed by DLG staff.





The worksheets can be used to calculate the limits on local government property tax revenue. Much of the data used in these worksheets can be found on the Certification of Valuations (CV) sent by the county assessor. Other data for the worksheets comes from the local governments' records. If you use any DOLA spreadsheets, please verify the results and if any problems are found, contact us to ensure use of the right data. 


The Certification of Levis for Non-School Governments, Form DLG 70 can be used to certify mill levies to the Board(s) of County Commissioners.

The blank Certification of Valuation (Form DLG 57) may be used by the county assessor to certify a local taxing entity's values for property taxation purposes. Assessors must certify valuation to each local taxing entity by August 25th of each year and then are permitted to re-certify valuation once by December 10th. The Property Tax Administrator requests that assessors provide the re-certification by December 1st to allow local governments time to finalize their budgets and certify their mill levies to the county commissioners by the December 15th deadline.
