For purposes of section 3304(a)(6)—

(1) except as otherwise provided in subsections (b) and (c), the services to which this paragraph applies are—

(A) service excluded from the term "employment" solely by reason of paragraph (8) of section 3306(c), and

(B) service excluded from the term "employment" solely by reason of paragraph (7) of section 3306(c); and

(2) the State law shall provide that a governmental entity, including an Indian tribe, or any other organization (or group of governmental entities or other organizations) which, but for the requirements of this paragraph, would be liable for contributions with respect to service to which paragraph (1) applies may elect, for such minimum period and at such time as may be provided by State law, to pay (in lieu of such contributions) into the State unemployment fund amounts equal to the amounts of compensation attributable under the State law to such service. The State law may provide safeguards to ensure that governmental entities or other organizations so electing will make the payments required under such elections.

This section shall not apply to service performed—

(1) in the employ of (A) a church or convention or association of churches, (B) an organization which is operated primarily for religious purposes and which is operated, supervised, controlled, or principally supported by a church or convention or association of churches, or (C) an elementary or secondary school which is operated primarily for religious purposes, which is described in section 501(c)(3), and which is exempt from tax under section 501(a);

(F) as an election official or election worker if the amount of remuneration received by the individual during the calendar year for services as an election official or election worker is less than $1,000;

(4) in a facility conducted for the purpose of carrying out a program of—

(A) rehabilitation for individuals whose earning capacity is impaired by age or physical or mental deficiency or injury, or

by an individual receiving such rehabilitation or remunerative work;

(5) as part of an unemployment work-relief or work-training program assisted or financed in whole or in part by any Federal agency or an agency of a State or political subdivision thereof or of an Indian tribe, by an individual receiving such work relief or work training; and

(6) by an inmate of a custodial or penal institution.

(c) Nonprofit organizations must employ 4 or more
This section shall not apply to service performed during any calendar year in the employ of any organization unless on each of some 20 days during such calendar year or the preceding calendar year, each day being in a different calendar week, the total number of individuals who were employed by such organization in employment (determined without regard to section 3306(c)(8) and by excluding service to which this section does not apply by reason of subsection (b)) for some portion of the day (whether or not at the same moment of time) was 4 or more.

(d) Election by Indian tribe
The State law shall provide that an Indian tribe may make contributions for employment as if the employment is within the meaning of section 3306 or make payments in lieu of contributions under this section, and shall provide that an Indian tribe may make separate elections for itself and each subdivision, subsidiary, or business enterprise wholly owned by such Indian tribe. State law may require a tribe to post a payment bond or take other reasonable measures to assure the making of payments in lieu of contributions under this section. Notwithstanding the requirements of section 3306(a)(6), if, within 90 days of having received a notice of delinquency, a tribe fails to make contributions, payments in lieu of contributions, or payment of penalties or interest (at amounts or rates comparable to those applied to all other employers covered under the State law) assessed with respect to such failure, or if the tribe fails to post a required payment bond, then service for the tribe shall not be excepted from employment under section 3306(c)(7) until any such failure is corrected. This subsection shall apply to an Indian tribe within the meaning of section 4(e) of the Indian Self-Determination and Education Assistance Act (25 U.S.C. 5304(e)).
