Important Information

Due Date for Return: The use tax amount computed from the table must be remitted with a copy of this return within 90 days of the date the equipment is first located in the City of Boulder. Late returns are not eligible for the 30-day proration and are subject to penalty and interest.

Amended Declaration Required: An amended declaration must be filed every 90 days or within 20 days of the date the equipment is moved out of the City of Boulder, whichever occurs first. Additional declarations are required if equipment not listed herein is used in the City.

  • Column a – Equipment Description & Identification Number. List a general description for the piece of equipment along with an identification number that may be used to trace the equipment to the taxpayer’s purchase records such as a serial number or asset tag number.
  • Column b – Date moved into city. List the date that CE is first brought into the city for use on the current project. This date will be used to determine the date that use tax is due (see Due Date above).
  • Column c – Date moved out of the city. List the date that CE is moved out of the city. For projects less than 90 days in duration, this date will be used to determine the date that use tax is due (see Due Date above).
  • Column d – Days in city. List the total number of consecutive days the equipment was located in the city.
  • Column e – Purchase price - List the full original purchase price of the equipment as per taxpayer’s records.
  • Column f – Date of purchase – List the date that equipment has been purchased as per taxpayer’s purchase records.
  • Column g – Value of Equipment – If purchased within five years of the date in column b, list the full original purchase price of the equipment (same as column e). If the equipment was purchased more than five years but less than 10 years before the date in column b, list the book value or fair market value, whichever is greater. If the equipment was purchased more than 10 years before the date in column b, enter zero (0).
  • Column h – Tax Credit. Credit may be taken against Boulder use tax for legally imposed sales or use taxes previously paid to Boulder, to other Colorado municipalities or to other states in accordance with section 3-2-9 B.R.C., 1981. Such credit may not exceed the Boulder use tax due. If no municipal or other state sales or use tax has been paid on the equipment, enter a zero in this column (h).
  • Column i – Net Equipment Value. If the amount in column (h) is greater than or equal to the amount in column g, enter a zero in this column (i).

    If the amount in column (h) is less than the amount in column (g), subtract the amount in column (h) from column (g) and enter the difference in this column (i).
  • Column j – Taxable Amount. Use tax may be prorated for equipment which is located in the city for 30 consecutive days or less provided that it is declared no later than 20 days from the removal of the equipment from the city.

    If the number in column (d) is greater than 30, enter the amount in column (i) in column (j). If the number in column (d) is less than or equal to 30, divide the amount in column (i) by 12 and enter the result in column (j).

    Complete each column for each piece of equipment. If additional lines are needed for more than seven pieces of equipment, attach additional schedules with the same information. For audit purposes, do not summarize all equipment in a single line.

Colorado Municipal Credit Amount

  • To compute a Colorado municipal credit amount, take the total of any previously paid, legally imposed municipal sales or use tax and divide this amount by 0.0386. Enter the result in this column (h).
  • Do not include State of Colorado, RTD, cultural district (CD), football district (FD), county, or other special district sales or use taxes. Credit is allowed only for legally imposed sales or use tax previously paid to other Colorado municipalities.
  • Example:
    • If a piece of equipment was purchased for $125,000 and a sales tax of 6.1% (consisting of 2.9% State tax, 1.2% RTD/CD/FD tax, and 2.0% city tax) was legally imposed (consisting of $2,500 in city sales tax; $7,625 in total sales tax),
    • The municipal credit amount would be $64,766.84 - ($2,500 city sales tax divided by 0.0386).

Other State Credit Amounts

  • To compute another state credit amount, take the total of any previously paid, legally imposed state sales or use tax and divide this amount by 0.08845. Enter the result in this column (h).
  • Example:
    • If a piece of equipment was purchased for $100,000 and a total state sales tax of 7.0% ($7,000) was legally imposed, the credit amount would be $79,140.76 - ($7,000 sales tax divided by 0.08845).
  • Note: Proof of payment of any taxes for which a credit is claimed must be submitted with the declaration.
