Sales and Use Tax Refund Policy

This Policy Statement has been cited in PS 2001(1)


PURPOSE: The purpose of this Policy Statement is to explain the Department’s policies on issuing refunds of sales and use taxes.


EFFECTIVE DATE: Effective upon issuance and applicable to all open tax periods, except that the procedures for filing protests of refund disallowances are applicable to refund claims filed on or after July 1, 1997.


STATUTORY AUTHORITY: Conn. Gen. Stat. §12-39s; §12-415; §12-418; §12-425, as amended by 1997 Conn. Pub. Acts 243, §56; and Conn. Gen. Stat. §12-431, as amended by 1997 Conn. Pub. Acts 243, §31.


RELEVANT LAW:

Conn. Gen. Stat. §12-39s(b) provides that if the Commissioner of Revenue Services determines that any tax, penalty or interest has been paid more than once or has been erroneously or illegally collected or computed, the Commissioner may either credit the amount against tax amounts then due and payable, or may refund it. The statute provides further that if a person is required to collect tax from another person and has collected the tax from the other person, any amount credited or refunded by the Commissioner shall be credited or refunded to the other person.

Conn. Gen. Stat. §12-425 sets out the specific procedures and requirements for refunds of sales and use taxes. No refund or credit will be allowed unless a claim is filed with the Commissioner within three years from the last day of the month next succeeding the period for which the overpayment was made. However, if the refund or credit relates to tax paid for an assessment made under §12-415 or §12-416, the refund claim must be made within six months after the assessment becomes final. Every claim must be in writing and must state the specific grounds on which the claim is founded.

Thus, a written refund claim that is timely and that states the specific legal and factual reasons for the claim will be considered properly filed for purposes of the statute. However, the Department will require additional documentation to substantiate a refund claim. These additional requirements are described in this Policy Statement.

There is no statutory provision for interest to be paid by the Department on sales and use tax refunds. 


WHO MAY SUBMIT SALES AND USE TAX REFUND CLAIMS:

  • The Department will accept refund claims filed by retailers on behalf of their purchasers, when the retailers can prove that they have collected the tax from the purchasers and remitted it to the Department, and when the retailers refund the tax to their purchasers as provided in this Policy Statement.
  • The Department will accept refund claims filed by purchasers: (a) when purchasers have self-assessed use tax and have not paid sales tax to retailers or (b) when purchasers have paid sales tax to retailers and have receipts for tax paid and submit copies of Form AU-524, Assignment of Retailer’s Rights for Refund, signed by retailers to which they paid tax, certifying that tax was collected from the purchasers and remitted to the Department, and that the retailers waive their right to claim refunds of the same amounts.

REFUND CLAIMS BY RETAILERS: Retailers may submit refund claims on behalf of purchasers using the following procedures:

A. When the Retailer is not Under Audit.

A retailer that is not under audit must file its refund claim in writing with the Audit Division, Refunds, Clearance and Adjustments Unit, 25 Sigourney Street, Hartford, CT 06106.

1. Required Documentation.

  • The retailer must provide proof that it collected the sales tax from its purchasers and remitted the tax to the Department. Proof will consist of copies of invoices to purchasers showing that tax was charged, and information satisfactory to the Department showing that the sales tax charged was reported on the retailer’s sales and use tax returns and that the tax was paid to the Department.
  • The retailer must submit amended sales and use tax returns for the periods with respect to which the refund is claimed.
  • The retailer must prove that the sales were not subject to sales and use taxes or that sales tax was otherwise paid in error. This proof may consist of properly completed exemption certificates, where appropriate.

2. Refunds by Retailers to Purchasers. If the Department determines that a retailer’s documentation is adequate, and that a refund claim should be allowed:

  • The retailer must prove that it has refunded the tax to its purchasers before the Department will issue a refund or credit to the retailer. This proof will consist of canceled checks from the retailer or receipts showing that the refund amounts have been credited to the purchasers’ accounts against amounts currently due and payable by the purchasers to the retailer.
  • Alternatively, the retailer must provide the Department with copies of letters or memoranda issued to its purchasers in which it promises either to refund the tax to them; or, for current, active customers of the retailer, to credit the refund amounts against amounts due from the purchasers.
  • If the retailer has not refunded the tax to its purchasers before the Department issues the refund to the retailer, then within 120 days after the Department issues the refund the retailer must prove that it has refunded or credited the refund amounts to its purchasers. This proof will consist of canceled checks from the retailer to the purchasers, or receipts showing that the refund amounts have been credited to the purchasers’ accounts against amounts currently due and payable by the purchasers to the retailer.
  • A retailer must immediately return to the Department any amounts not refunded or credited to the retailer’s purchasers within 120 days after the Department issues a refund. Retailers are subject to audit, and will be assessed under Conn. Gen. Stat. §12-415 for amounts not properly refunded to purchasers or returned to the Department.

B. When the Retailer is Under Audit. A retailer that is under audit must file its refund claim in writing with the Audit Division’s Revenue Examiner assigned to the audit.

1. Required Documentation.

  • The refund claim must be filed before the Department issues Form AU-100, Tax Determination Report. Any refund claim filed after the Department issues Form AU-100 will not be considered by the Revenue Examiner, and must be filed in writing with the Refunds, Clearance and Adjustments Unit of the Audit Division.
  • A retailer under audit must submit to the Revenue Examiner the same information and documentation required of retailers not under audit (see above). However, the retailer need not file amended sales and use tax returns, since the refund, if allowed, will be incorporated into the audit.

2. Refunds by Retailers to Purchasers. If the Revenue Examiner determines that a retailer’s documentation is adequate, and that a refund should be allowed:

  • The retailer must provide to the Revenue Examiner the same documentation and proof that tax has or will be refunded or credited to purchasers that is required of retailers not under audit (see above).
  • No audit projections for retailers. Refund claims filed by retailers on behalf of purchasers must be accompanied by fully detailed documentation with respect to every sale. The Department will not project or otherwise estimate such refunds using sampling methods.
  • No interest offsets for retailers. The Department will not use refunds issued to retailers on behalf of purchasers to offset audit assessments for purposes of reducing interest or penalties on such assessments.

C. Calculation Errors. A retailer may sometimes make calculation errors or otherwise erroneously overpay tax, where the retailer has not incorrectly charged tax to its purchasers. If this occurs, the retailer should amend its sales and use tax returns, and if the Department confirms that errors were made, sales tax will be refunded to the retailer. If the retailer has claimed the refund during an audit, a refund of tax overpaid because of a calculation error may be used to offset the audit assessment for purposes of reducing the interest or penalty on the assessment.


REFUND CLAIMS BY PURCHASERS: Purchasers may submit refund claims using the following procedures:

A. When the Purchaser is not Under Audit. A purchaser that is not under audit must file its refund claim in writing with the Audit Division, Refunds, Clearance and Adjustments Unit, 25 Sigourney Street, Hartford, CT 06106.

1. When the Purchaser has Paid Tax to a Retailer.

a. Required Documentation.

  • The purchaser must prove that it paid tax to a retailer registered to collect Connecticut sales and use taxes. This proof will consist of receipts or invoices from retailers, canceled checks or other information satisfactory to the Department showing that the retailer billed and received the tax.
  • The purchaser must prove that the purchases were not subject to sales and use taxes or that sales and use taxes were paid in error. This proof may consist of properly completed exemption certificates, where appropriate.
  • The purchaser must prove that the retailer remitted the tax to the Department, and satisfy the Department that the retailer will not independently seek a refund of the same tax for which the purchaser is requesting a refund.

b. Certification Requirement. This proof will consist of a completed Form AU-524, Assignment of Retailer’s Rights for Refund, or subsequent form issued by the Department. Form AU-524 provides detailed information about the purchaser’s purchases from the retailer, and requires the retailer to certify under penalties of false statement (a) the accuracy of the information, (b) that the retailer paid the tax it collected to the Department, and (c) that the retailer disclaims any interest in the refund and assigns its right to the refund to the purchaser.

  • The Department will not consider any claim for refund from a purchaser that paid tax to a retailer unless the purchaser provides a completed Form AU-524 from the retailer to which the purchaser paid the tax.
  • The only exception to the requirement of a Form AU-524 from a retailer is if the retailer is out of business.

2. When the Purchaser has not Paid Tax to a Retailer.

  • When the purchaser has not paid tax to a retailer, but has self-assessed use tax on purchases, the purchaser must prove that it paid tax to the Department. This proof will consist of copies of the purchaser’s tax returns and canceled checks, with invoices or receipts for the purchases and worksheets that correlate to the amount of use tax paid with the returns.
  • The purchaser must prove that the purchases were not subject to sales and use taxes, or that use tax was otherwise paid in error.

B. When the Purchaser is Under Audit. A purchaser that is under audit must file its refund claim in writing with the Audit Division’s Revenue Examiner assigned to the audit.

1. Required Documentation.

  • The refund claim must be filed before the Department issues Form AU-100, Tax Determination Report. Any refund claim filed after the Department issues Form AU-100 will not be considered by the Revenue Examiner, and must be filed in writing with the Refunds, Clearance and Adjustments Unit of the Audit Division.
  • A purchaser under audit must submit to the Revenue Examiner the same information and documentation required of purchasers not under audit (see above). However, the purchaser need not file amended sales and use tax returns, since the refund, if allowed, will be incorporated into the audit.

2. Audit Projections and Offsets. If the Revenue Examiner determines that a purchaser’s documentation is adequate, and that a refund should be allowed:

  • No audit projections when tax paid to retailer.

Refund claims by purchasers of tax paid to retailers must be accompanied by fully detailed documentation with respect to every sale. The Department will not project or otherwise estimate such refunds using sampling methods.

  • Audit projections allowed for self-assessed use tax. Refund claims by purchasers of self-assessed use tax that was paid directly to the Department may be projected over the audit using sampling methods, if the Revenue Examiner is satisfied that the sampling method accurately reflects the correct refund. If the Department does project a refund of self-assessed use tax, the purchaser must waive its right to any other refunds of self-assessed use tax with respect to the same audit period.
  • Interest offsets when tax paid to retailers. The Department will allow purchasers that have paid tax to retailers to use refunds to offset audit assessments for purposes of reducing interest or penalties on such assessments.
  • Interest offsets allowed for self-assessed use tax. The Department will allow purchasers that have self-assessed use tax to use refunds to offset audit assessments for purposes of reducing interest or penalties on such assessments.

REFUNDS OF USE TAX PAID ON MOTOR VEHICLES, SNOWMOBILES, VESSELS AND AIRCRAFT: Conn. Gen. Stat. §12-431(a), as amended by 1997 Conn. Pub. Acts 243, §31, provides that purchasers of motor vehicles, snowmobiles, vessels and aircraft other than from licensed motor vehicle dealers or lessors, snowmobile dealers, licensed marine dealers or retailers of aircraft will not pay sales tax to the sellers, but must pay use tax on such items, unless the purchases are exempt under the statute.

Conn. Gen. Stat. §12-431(b) and Conn. Agencies Regs. §12-431(b)-1 provide that the value of a motor vehicle in the current month’s N.A.D.A. Official Used Car Guide, Eastern Edition, is presumed to be the total purchase price of the vehicle. When the motor vehicle is registered, the Department of Motor Vehicles will collect use tax on the greater of the N.A.D.A. book value or the amount paid for the motor vehicle. If the purchaser can prove to the satisfaction of the Commissioner that the purchase price was lower than the N.A.D.A. book value, the purchaser may claim a refund of the excess use tax paid, using CERT-106, Claim for Refund of Use Tax Paid on Motor Vehicle Purchased from Other than a Motor Vehicle Dealer, and following the instructions on the form.

A purchaser claiming any other refund of use tax paid on the purchase of a motor vehicle, or a refund of use tax paid on the purchase of a snowmobile, vessel or aircraft, must file the claim with the Audit Division, Refunds, Clearance and Adjustments Unit, 25 Sigourney Street, Hartford, CT 06106.


TIME LIMITS FOR FILING REFUND CLAIMS: Conn. Gen. Stat. §12-425(1) has two different time limits for filing refund claims. A refund claim is considered to be "filed" on the date the claim is postmarked or hand delivered and date stamped by the Department.

In general, a refund claim must be filed within three years from the last day of the month next succeeding the period for which the refund claim is made. For example, a refund claim filed on July 31, 1998, may apply to tax paid with respect to the monthly or quarterly return for the period ending June 30, 1995. Tax periods held open by waiver under Conn. Gen. Stat. §12-415(8) will also be held open for purposes of filing refund claims.

If a refund claim relates to tax paid for an assessment made under Conn. Gen. Stat. §12-415 or §12-416, the claim must be filed within six months after the assessment becomes final. Section 12-418 provides that an assessment becomes final 60 days after service of the notice of assessment on the taxpayer, unless a petition for reassessment (protest) is filed. If a protest is filed, the assessment becomes final one month after service on the taxpayer of the Department’s final determination of the protest. For example, a refund claim that relates to tax paid for an assessment under Conn. Gen. Stat. §12-415 must be filed within 60 days plus six months from the date of the first billing of the audit assessment. However, if the taxpayer pays the tax and protests the assessment, the refund claim must be filed within seven months (one month plus six months) from the date of the Appellate final determination letter.

A taxpayer filing a refund claim with respect to tax paid for an assessment made under Conn. Gen. Stat. §12-415 or §12-416 must file it in writing with the Audit Division, Refunds, Clearance and Adjustments Unit, 25 Sigourney Street, Hartford, CT 06106.


DISALLOWANCE OF REFUND CLAIMS: Conn. Gen. Stat. §12-425(5), as amended by 1997 Conn. Pub. Acts 243, §56, sets out the procedures to be followed by the Department and taxpayers in connection with the disallowance of refund claims.

The Department’s notice of disallowance of a refund claim will be in writing and will be mailed to the taxpayer. Service of the notice is complete at the time of deposit in the United States post office or mail box.

In the case of a refund disallowance by the Refunds, Clearance and Adjustments Unit of the Audit Division, the taxpayer may file a written protest of the disallowance, setting forth the grounds on which the protest is based, within 60 days of the Department’s mailing of the notice of disallowance to the taxpayer.

In the case of a refund disallowance by a Revenue Examiner when the taxpayer is under audit, the taxpayer may file a written protest of the disallowance, setting forth the grounds on which the protest is based, within 60 days of the Department’s mailing of the written notice of disallowance to the taxpayer. (NOTE: In some cases, the notice of refund disallowance may be mailed to the taxpayer before an audit assessment bill is sent, thereby setting a different 60-day period within which to protest the refund disallowance than the period within which to protest the audit assessment.)

A taxpayer should address its protest of a refund disallowance to the Commissioner of Revenue Services, Appellate Division, 25 Sigourney Street, Hartford, CT 06106.

Within one month of the Department’s mailing of a notice of final determination following a protest of a refund disallowance, the taxpayer may appeal the determination to the Superior Court, under the procedures set forth in Conn. Gen. Stat. §12-422.


THE "BUY CONNECTICUT" REFUND PROVISION: The "Buy Connecticut" provision, 1997 Conn. Pub. Acts 243, §48, contains special rules to be followed to obtain refunds of sales and use taxes paid on tangible personal property to be transported outside Connecticut by businesses for exclusive use outside the state. See Special Notice 98(10), The "Buy Connecticut" Provision, for details.


EFFECT ON OTHER DOCUMENTS: This Policy Statement supersedes Policy Statement No. 91-3, Procedures Followed in Allowing or Disallowing Claims for Refund of Sales and Use Taxes that Purportedly Have Been Overpaid.


EFFECT OF THIS DOCUMENT: A Policy Statement is a document that explains in depth a current Department policy or practice affecting the liability of taxpayers. Unlike a Ruling, a Policy Statement does not apply a policy or practice to a specific set of facts but it may be referred to for general guidance by taxpayers. Unlike a Special Notice, it does not announce a new policy or practice in response to changes in state or federal laws or regulations or to judicial decisions.
