Q & A on Sales and Use Taxes for a New Business

This publication has been modified and superseded by IP 92(1.5)

INTRODUCTION:  Although most Connecticut residents are familiar with the fact that the state has a sales tax, very few people know much about the tax. Lack of knowledge can be costly for the owner of a small business. State law requires businesses to collect sales tax in exchange for the privilege of doing business in Connecticut. A retailer that fails to collect the tax can lose its permit to do business in Connecticut and owe penalty and interest in addition to the tax.  Basic information is provided in this publication to help businesses and individuals avoid the most obvious and potentially costly errors.  For more detailed information, request IP 94(5.1), Getting Started in Business:  Understanding Connecticut Taxes, from the DRS Forms Unit.

WHAT IS THE SALES TAX?

The sales tax is a levy imposed on the sale, rental or lease of most goods and certain services at a rate of 6%. The tax is collected by the retailer and remitted directly to the state. There is also a 12% room occupancy tax on the rental of rooms in hotels, motels or lodging houses.

MUST I MAKE A MINIMUM AMOUNT OF SALES BEFORE I AM REQUIRED TO REGISTER FOR COLLECTION OF SALES TAX?

No. You are required to register before you start your business.

HOW DO I REGISTER MY BUSINESS?

You can register for a Sales and Use Tax Permit either by mail or in person at the Department of Revenue Services, 25 Sigourney Street, Hartford, CT 06106-5032. You can also register at DRS regional offices located in Bridgeport, Hamden, Waterbury and Norwich. Check the blue pages of your telephone book for the address of the office nearest to you.

Use Form REG-1, Application For Tax Registration Number, to register for a Sales and Use Tax Permit as well as to register for:

  • Room occupancy tax
  • Cigarette tax (over the counter retail)
  • Admission, dues and cabaret tax
  • Unrelated business income tax
  • Connecticut income tax withholding
  • Corporation business tax
  • Tourism account surcharge on the rental or leasing of passenger motor vehicles
  • Business use tax
  • Tire fee (scheduled for repeal July 1, 1997)
  • Dry cleaning establishment surcharge

FOR WHAT OTHER TAXES IS A BUSINESS BE LIABLE FOR?

A business may be liable for state taxes administered by another state agency or for federal taxes.  Request a copy of IP 92(6.2), Business Taxes, from the Forms Unit for information about state taxes administered by other state agencies.  

The Internal Revenue Service (IRS) should also be contacted to determine your federal tax requirements.  The Internal Revenue Service telephone number is 1-800-829-1040.  Walk-in assistance is available at the IRS office at 135 High Street in Hartford and other locations throughout Connecticut.  Check the blue pages of your telephone book.

ONCE I HAVE A SELLER'S PERMIT, WILL I EVER NEED TO GET ANOTHER ONE?

A seller's Sales and use Tax Permit is issued for two years for a fee of $20.  The permit may be renewed at the end of that period without an additional fee.

Each new business location must have its own Sales and Use Tax Permit. If your  business expands and you open a second location, you must obtain a new permit for the new location.

Also, if the ownership or structure of the business changes for federal tax purposes (for example, if a sole proprietorship becomes a partnership or corporation), a new permit must be obtained.

I PERFORM A TAXABLE SERVICE AND SELL TAXABLE GOODS FROM THE SAME LOCATION. DO I NEED MORE THAN ONE SALES AND USE TAX PERMIT?

No. Only one permit is required. It allows you to collect tax for sales of goods and services, as well as rentals and leases made at the same business location.

WHAT IF MY BUSINESS IS LOCATED OUT-OF-STATE AND I INTEND TO MAKE SALES INTO CONNECTICUT THROUGH THE MAIL OR BY COMMON CARRIER?

You may register to collect Connecticut use tax on your sales in this state. Request SN 92(19), Effect of Quill Corp. v. North Dakota on the Collection of Use Tax by Retailers Who Engage in Business in Connecticut Only by Selling Items Through Mail Order Catalogs With Delivery by Common Carrier, from the DRS Forms Unit for further information concerning sales by mail order companies.   

If you wish to register, complete Form REG-7, Application For Authority To Collect Connecticut Use Tax.  However, if you come into Connecticut to conduct business or you have a business location in this state, you must obtain a Connecticut Sales and Use Tax Permit.  

WHAT IF MY BUSINESS IS LOCATED OUT-OF-STATE BUT I INTEND TO COME INTO CONNECTICUT AND SELL (FOR EXAMPLE, AT A CRAFT SHOW OR FLEA MARKET)?

You must complete a Form REG-1. You will be issued a Connecticut Sales and Use Tax Permit and will be required to collect Connecticut sales tax. You must obtain a Connecticut Sales and Use Tax Permit if you will perform any taxable services in this state.

HOW DO I OBTAIN A NEW COPY OF MY SALES AND USE TAX PERMIT IF I CHANGE MY ADDRESS OR LOSE THE PERMIT?

Notify DRS in writing at the following address:

Department of Revenue Services
Registration Section
25 Sigourney Street 
Hartford Connecticut 06106

There is no fee for this service.

HOW OFTEN ARE SALES AND USE TAX RETURNS FILED?

Generally, sales and use tax returns must be filed on a quarterly basis. The quarterly periods and due dates are as follows:

Periods Due Dates
January 1 - March 31 
 April 30
April 1 - June 30
 July 31
July 1 - September 30
October 31
October 1 - December 31
January 31

If your sales and use tax liability exceeds $4,000 per year, you must file monthly. Monthly returns are due at the end of the following month. You may request to file on an annual basis if your sales and use tax liability is less than $1,000 per year.

SHOULD I FILE A RETURN IF I HAVE MADE NO SALES ?

Yes. The return must be completed by showing "zero sales" and "zero taxes due."

ON WHAT PRICE DO I COMPUTE THE SALES TAX?

The tax is computed on the price of the sale, rental or lease (not your cost) of the  goods or service.  The tax must be billed to your customers in one of two ways:

1. Tax included, in which case the bill must be marked "tax included,"
    or  2. The tax is added to the sales price, and separately stated on the bill.

If you bill your customers "tax included", you must keep records showing the cost of the sale price of the goods or services and the tax charged.

IF I BILL MY CUSTOMERS "TAX INCLUDED," HOW DO I REPORT MY GROSS RECEIPTS ON LINE 1 OF THE SALES AND USE TAX RETURN?

Multiply the amount you billed your customer by 94.3% (.943). The result is your gross receipts, which must be reported on the gross receipts line of your tax return.

Example:

Billed amount (tax included) $100.00
Multiplication factor(94.3%) x  0.943
Gross receipts (Line 1)   $94.30

WHEN DO I REPORT SALES THAT I MAKE?

In general, sellers of goods and taxable services must report sales on the accrual basis. This means that all sales you make must be reported during the filing period in which the sale is made, not when the customer renders payment.

WHEN MAY A SELLER REPORT SALES TAX ON THE CASH BASIS?

Sellers of certain services who file with the IRS on the cash basis, may be able to file sales and use tax returns on the cash basis. Contact the DRS Taxpayer Services Division for further information on those who may file on the cash basis.

HOW DO I PURCHASE MY INVENTORY OR GOODS FOR RESALE WITHOUT PAYING SALES TAX?

Complete a Connecticut Sales and Use Taxes Resale Certificate, and give it to the vendor from whom you make a purchase of goods or services which you intend to resell in the regular course of business.  For further information, request a copy of IP 93(4.2), Notice to Retailers Regarding Sales and Use Tax Resale Certificate.

A certificate may not be used to purchase items for used to purchase items for use by yourself or your business, such as office supplies, furniture and fixtures. Such purchases are subject to use tax if you do not pay Connecticut sales tax.  Request a copy of IP 93(3.1), Q & A on Use Tax for Businesses and Professions, for further information..

WHAT MUST MY CUSTOMERS PROVIDE TO ME TO DEMONSTRATE THAT THEY ARE EXEMPT FROM PAYING SALES TAX?

The customer must give you a completed Connecticut Sales and Use Tax Resale Certificate or other approved exemption certificate.   Retailers making sales in Connecticut should not accept exemption certificates issued by other states.  See IP 94(5.1), Getting Started in Business:  Understanding Connecticut Taxes, for a list of exemptions and certificates.  If you have a question about the validity of an exemption claimed by a customer contact DRS Taxpayer Services.

IF I MAKE A SALE AND DELIVER THE GOODS OUTSIDE CONNECTICUT, DO I COLLECT CONNECTICUT SALES TAX?

No. If the title to the goods transfers to the purchaser outside Connecticut, Connecticut sales tax does not apply.  An example of this is when a Connecticut mail order catalog company mails its goods or has them shipped to a customer outside Connecticut but the title to the goods remains with the catalog company until delivery to the customer.  However, depending upon your activities in the other state, you may be required to register and collect sales tax for that state. 

Connecticut businesses may elect to collect tax on behalf of New York State if they participate in the New York/Connecticut Sales Tax Agreement. Contact the DRS Taxpayer Services for information about this agreement. 

If you make a sale in Connecticut, you must collect Connecticut sales tax, even if the buyer lives in another state.  If you make a sale outside of Connecticut but you deliver the goods in Connecticut, you are also required to collect Connecticut sales tax. 

WHAT ARE THE PENALTIES AND INTEREST FOR LATE FILING OF A SALES AND USE TAXES RETURN?

There is a penalty of $50 or 15% of the tax due (whichever is greater) for the late payment of the tax. Interest of 1% per month or a fraction of a month is calculated on the underpayment of tax.

WHAT RECORDS MUST I KEEP TO VERIFY THE FIGURES ON MY SALES AND USE TAXES RETURN?

The following records must be kept at least three years:

  • Sales receipts
  • Purchase invoices
  • Cash register tapes
  • State and federal tax returns
  • Documents that show price changes
  • Exemption certificates

Under certain circumstances, you may be required to produce records for more than three years.

I AM CLOSING MY BUSINESS. WHAT SHOULD I DO?

You must cancel your sales and use tax permit by doing the following:

  1. File your monthly, quarterly or annual return and enter the last business date in the block provided
  2. Write the word "FINAL" prominently across the top of the return, and
  3. Complete the back of the permit and enclose your permit card with the return.

IF I PURCHASE A BUSINESS, AM I OBLIGATED FOR THE PREVIOUS OWNER'S SALES TAX LIABILITY?

Yes. To avoid this, obtain a Sales Tax Certificate of Clearance by calling DRS Sales Tax Office Audit at (860) 541-7520 prior to paying the purchase price to the seller. The purchaser of a business is liable for the taxes of the previous owner to the extent of the purchase price unless a Sales Tax Certificate of Clearance is obtained from this Department.
