Frequently Asked Questions

What is the statutory “5.5%” Property Tax Revenue Limit?

The statutory "5.5%" Property Tax Revenue Limit, also known as the "Annual Levy Law" (Section 29-1-301, et seq., C.R.S) restricts the amount of total property tax revenue that a local government may collect each year. The limit applies to the amount of property tax revenue that is collected on a local government’s entire tax base.

Which local governments are subject to the “5.5%” limit?

The limit applies to most statutory local governments that levy for property taxes. It does not apply to home-rule municipalities. The limit also does not apply to local governments that have successfully held a vote to waive the limit. A list of waived local governments is available here: https://dola.colorado.gov/lgis/dlg53EntityAlpha.jsf.

Is the “5.5%” limit the same thing as TABOR?

No. The "5.5%" Property Tax Revenue Limit is not a TABOR limit found in Article X, Section 20 of the Colorado Constitution. The Division of Local Government (the Division) does not calculate or enforce TABOR limits.

A local government is “de-Bruced”; does this mean the "5.5%" limit does not apply to that local government?

“De-Brucing” is a broad term that describes a large variety of ballot languages that voters can approve to remove some TABOR spending and revenue limits from a local government. Each local government’s TABOR history and status can be unique and requires case-by-case legal review (usually by a local government or bond attorney). In many cases, the same voter-approved ballot language might also waive the “5.5%” limit for the local government, but this depends on the ballot language. The Division cannot make a determination on the local government’s TABOR status.

I am a homeowner/property owner and my tax bill increased. Does the “5.5%” limit apply to my tax bill?

No. The limit does not apply to the tax bills of individual property taxpayers because the limit applies to the total property tax revenue collected on all property taxpayers in a local government.

Calculation of the Revenue Limit

A spreadsheet is available to assist in calculating the statutory property tax revenue limitation, however, the Division also calculates the government's "5.5%"limit. This is done in August/September and again in November/December following the county assessors’ re-certification of valuation.

These reports will update each day with any changes processed by Division staff.

Local governments should compare the "5.5%" limit with TABOR limits to determine which is the most restrictive property tax limitation.

Contact program staff listed below for assistance calculating the "5.5%" limit.

The preliminary calculations will be essential to the budget building process, however, the final calculations may require some adjustments prior to budget adoption and certification of mill levies.



The Division has a statutory role in determining compliance with the "5.5%" limit (C.R.S. 29-1-301(6)). The Division sends annual notice in April or May to the taxing entities that appear to exceed the "5.5%" revenue limit. Where a taxing entity exceeds the limitation, the Division shall order a reduction in the authorized revenue of the taxing entity for the subsequent year in an amount which offsets the revenue in excess of the "5.5%" limit (CRS 29-1-301(6)).

If a taxing entity’s electors have voted to “waive” the "5.5%" limit (CRS 29-1-302(2)(b)), Division staff will review the ballot language and certified election results. After being deemed a sufficient waiver, the taxing entity will be notified that Division will no longer calculate the "5.5%" revenue limit. This determination is not above legal challenge and does not find a taxing entity to be exempt from TABOR limitations or other limitations to the operating mill levy. A taxing entity must request that the Division review election results. Contact staff listed below for assistance.​

Assessor Certification of Valuation

The Certification of Valuation (Form DLG 57) is used by the county assessor to certify a local taxing entity's values for property taxation purposes.
