Conn. Gen. Stat. § 31-225a
(b)
(1) The administrator shall maintain for each employer, except reimbursing employers, an experience account in accordance with the provisions of this section. (2) With respect to each benefit year commencing on or after July 1, 1978, regular and additional benefits paid to an individual shall be allocated and charged to the accounts of the employers who paid the individual wages in his or her base period in accordance with the following provisions: The initial determination establishing a claimant's weekly benefit rate and maximum total benefits for his or her benefit year shall include, with respect to such claimant and such benefit year, a determination of the maximum liability for such benefits of each employer who paid wages to the claimant in his or her base period. An employer's maximum total liability for such benefits with respect to a claimant's benefit year shall bear the same ratio to the maximum total benefits payable to the claimant as the total wages paid by the employer to the claimant within his or her base period bears to the total wages paid by all employers to the claimant within his or her base period. This ratio shall also be applied to each benefit payment. The amount thus determined, rounded to the nearest dollar with fractions of a dollar of exactly fifty cents rounded upward, shall be charged to the employer's account.
*(c) (1) (A) Any week for which the employer has compensated the claimant in the form of wages in lieu of notice, dismissal payments or any similar payment for loss of wages shall be considered a week of employment for the purpose of determining employer chargeability. (B) No benefits shall be charged to any employer who paid wages of five hundred dollars or less to the claimant in his or her base period. (C) No dependency allowance paid to a claimant shall be charged to any employer. (D) In the event of a natural disaster declared by the President of the United States, no benefits paid on the basis of total or partial unemployment which is the result of physical damage to a place of employment caused by severe weather conditions including, but not limited to, hurricanes, snow storms, ice storms or flooding, or fire except where caused by the employer, shall be charged to any employer. (E) If the administrator finds that (i) an individual's most recent separation from a base period employer occurred under conditions which would result in disqualification by reason of subdivision (2), (6) or (9) of subsection (a) of section 31-236, or (ii) an individual was discharged for violating an employer's drug testing policy, provided the policy has been adopted and applied consistent with sections 31-51t to 31-51aa, inclusive, section 14-261b and any applicable federal law, no benefits paid thereafter to such individual with respect to any week of unemployment which is based upon wages paid by such employer with respect to employment prior to such separation shall be charged to such employer's account, provided such employer shall have filed a notice with the administrator within the time allowed for appeal in section 31-241. (F) No base period employer's account shall be charged with respect to benefits paid to a claimant if such employer continues to employ such claimant at the time the employer's account would otherwise have been charged to the same extent that he or she employed him or her during the individual's base period, provided the employer shall notify the administrator within the time allowed for appeal in section 31-241. (G) If a claimant has failed to accept suitable employment under the provisions of subdivision (1) of subsection (a) of section 31-236 and the disqualification has been imposed, the account of the employer who makes an offer of employment to a claimant who was a former employee shall not be charged with any benefit payments made to such claimant after such initial offer of reemployment until such time as such claimant resumes employment with such employer, provided such employer shall make application therefor in a form acceptable to the administrator. The administrator shall notify such employer whether or not his or her application is granted. Any decision of the administrator denying suspension of charges as herein provided may be appealed within the time allowed for appeal in section 31-241. (H) Fifty per cent of benefits paid to a claimant under the federal-state extended duration unemployment benefits program established by the federal Employment Security Act shall be charged to the experience accounts of the claimant's base period employers in the same manner as the regular benefits paid for such benefit year. (I) No base period employer's account shall be charged with respect to benefits paid to a claimant who voluntarily left suitable work with such employer (i) to care for a seriously ill spouse, parent or child or (ii) due to the discontinuance of the transportation used by the claimant to get to and from work, as provided in subparagraphs (A)(ii) and (A)(iii) of subdivision (2) of subsection (a) of section 31-236. (J) No base period employer's account shall be charged with respect to benefits paid to a claimant who has been discharged or suspended because the claimant has been disqualified from performing the work for which he or she was hired due to the loss of such claimant's operator license as a result of a drug or alcohol test or testing program conducted in accordance with section 14-44k, 14-227a or 14-227b while the claimant was off duty.
(e)
(1) As of each June thirtieth, the administrator shall determine the charged tax rate for each qualified employer. Said rate shall be obtained by calculating a benefit ratio for each qualified employer. The employer's benefit ratio shall be the quotient obtained by dividing the total amount chargeable to the employer's experience account during the experience period by the total of his or her taxable wages during such experience period which have been reported by the employer to the administrator on or before the following September thirtieth. The resulting quotient, expressed as a per cent, shall constitute the employer's charged tax rate. If the resulting quotient is not an exact multiple of one-tenth of one per cent, the charged rate shall be the next higher such multiple, except that if the resulting quotient is less than five-tenths of one per cent, the charged rate shall be five-tenths of one per cent and if the resulting quotient is greater than five and four-tenths per cent, the charged rate shall be five and four-tenths per cent. The employer's charged tax rate will be in accordance with the following table:
