Return Filing Guide

 GENERAL QUESTIONS 

 How often must I file? 

 Depending on your filing schedule, your business will receive a sales and use tax form on a 
 regular basis. 

   Average tax due is more than $100/month: at the end of each month. 
   Average tax due is between $20 and $100/month: at the end of each quarter. 
   Average tax due is less than $20/month: at the end of each year. 

 Why is filing required? 

   It’s the law:  City Code section 22-40. 
   Sales taxes collected by retailers are public funds held in trust – they NEVER belong to 
    the collector. 

 Complete returns are important! 

 Gross sales data aids in determining the City’s gross production for economic analysis and 
 development purposes. 

   Deductions data tells us more about the makeup of the City’s economy. 
   Based on this information and other input, the City determines projects, programs and 
    service needs. 

 Hey, I don’t sell things! 

 Everyone is familiar with sales tax, which is recognized as public money that must be paid to the 
 City. However, use tax is also required 

   City Code section 22-66(a) 
   Service businesses might have a use tax liability, which is a tax paid on items used in 
    business or rendering services if no local sales tax was paid on their purchase. 
   Use Tax Made Simple: The City offers via email, web, CD, hard copy or classes, 
    instruction on use tax as it applies to businesses in Wheat Ridge. 
   Watch for notice of classes or contact us for a copy of the material if you don’t use the 
    web:

Line 1: Gross Sales and Service 

 On this line report the total sales by your business, even if they’re not taxable: 

                 Retail sales of tangible personal property; 
                 Rentals of tangible personal property; 
                 Leases of tangible personal property; 
                 Service and labor sales; 
                 Sales shipped or delivered out of the City; 
                 DO NOT INCLUDE TAX COLLECTED. 
                 Gross sales if coin operated 
                 Sales via vending machines are taxable, be they food, beverages or use of 
                  equipment such as games, vacuums, car wash equipment or laundry 
                  equipment.  
                 Gross sales/taxable sales is calculated by the gross receipts method (this 
                  presumes city tax only): 
                   o Gross sales = Gross receipts x (1 – tax rate)   
                   o Currently:  gross sales = gross receipts /1.035 
                   o Tax = (gross receipts – gross sales)  or(gross sales x 3.5%) 

Line 2 A: Bad Debts Collected: This applies to businesses using accrual-based accounting. 

  Because bad debts are allowed as a deduction, collections on them must be added back in 
   to current business. 
  If you didn’t take a deduction previously, do not add bad debts back in. 

Line 2B: Total Gross Sales 

Sum Lines 1 and 2A 

Line 3: These are the itemized deductions from gross sales to arrive at taxable sales as allowed 
by the City Code. 

 Line 3A: Non-Taxable Service Sales Included in Line 1

 Line 3B:  Sales to Other Licensed Dealers for Resale Purposes 

  City Code section 22-58(20) 
  Good faith in allowing the exemption is required:   
            o Example:  an auto repair shop does not sell steak in the ordinary course of 
              business; don’t make an exempt sale of steaks to an auto repair shop. 
            o Items to be used by a reseller in conducting his business are subject to sales 
              tax. 

 Line 3C: Sales Shipped Out of the City and/or State 

  Code section 22-58(15) 
  Keep shipping terms documentation to prove where title passed. 
  Invoices must bear a “shipped to” address and method of delivery consistent with it. 
            o Example:  If an invoice indicates shipping address outside the City, but 
              delivery is marked “customer pick up,” the exemption will be disallowed if no 
              shipping documents prove delivery outside the City. 
  This can be a complex area; if in doubt, ask for City assistance. 

 Line 3D: Bad Debts Charged Off 

  City sales tax was previously remitted. 
  You use accrual basis accounting. 
  Report the amount of uncollected accounts that was written off during the reporting 
   period. 

 Line 3E: Trade-Ins for Taxable Resale 

  The value allowed on trade-ins that will be sold in the ordinary course of business, 
   including sale as scrap, is equivalent to a purchase for resale and is a deduction to 
   gross sales. 
  If a trade-in is later used in your business before being sold or otherwise disposed of, 
   its trade-in value at the time it was traded is subject to use tax. 

 Line 3F: Sales of Gasoline and Cigarettes 

  All motor fuels on which gasoline or special fuels tax has been paid or accrued under 
   CRS 39-27-102 are exempt. 
  Other tobacco products, such as chew and loose leaf tobacco, are taxable. Do not

 Line 6: Add Excess Tax Collected 

      All tax collected must be remitted. 
      Add up all the tax you collected during the reporting period and allocate it between the 
       State and City.  Here’s how: 
         o  If your business is in Jefferson County, Colorado 
                    State’s share = tax collected x .60 (.045/.08)    
         o  If your business is not in Jefferson County, Colorado 
                    State’s share = all tax collected x .57 (.04/.08) 
         o  City’s share = all tax collected – State’s share 
      Is the City’s share amount larger than the sales tax you calculated on line 5? 
         o  Yes:  subtract the amount on line 5 from this amount, the remainder is excess tax 
            due to the City.  Enter it on Line 6. 
         o  No:  enter 0 on line 6 
      You must still pay what’s owed even if you did not collect enough.   

 Line 7: Adjusted City Tax 

      The sum of calculated tax and excess tax collected is adjusted City tax. 
      Add Lines 5 and 6 
      This ensures all money people paid as tax is remitted to taxing authorities.   
      Remember, funds collected as tax are never the property of the business! 

 Line 8: Vendor Fee 

      The vendor fee (commission you keep) is available only if the return is postmarked by 
       the due date. 
      The vendor fee is 2 percent of adjusted sales tax only, including excess sales tax 
       collected. 
      The vendor fee is limited to $100 per return.   

 Line 9: Total City Tax 

 Subtract line 8 (vendor fee) from line 7.
