 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


 To the Board of Trustees
 Jack Henry & Associates, Inc.
 401(k) Retirement Savings Plan:

 We have audited the accompanying statements of net assets available for
 benefits of Jack Henry & Associates, Inc. 401(k) Retirement Savings Plan
 (the "Plan") as of December 31, 2005 and 2004 and the related statement of
 changes in net assets available for benefits for the year ended December 31,
 2005. These financial statements are the responsibility of the Plan's
 management. Our responsibility is to express an opinion on these financial
 statements based on our audits.

 We conducted our audits in accordance with standards of the Public Company
 Accounting Oversight Board (United States). Those standards require that we
 plan and perform the audit to obtain reasonable assurance about whether the
 financial statements are free of material misstatement. The Plan is not
 required to have, nor were we engaged to perform, an audit of its internal
 control over financial reporting. Our audits included consideration of
 internal control over financial reporting as a basis for designing audit
 procedures that are appropriate in the circumstances, but not for the
 purpose of expressing an opinion on the effectiveness of the Plan's internal
 control over financial reporting. Accordingly, we express no such opinion.
 An audit also includes examining, on a test basis, evidence supporting the
 amounts and disclosures in the financial statements, assessing the
 accounting principles used and significant estimates made by management, as
 well as evaluating the overall financial statement presentation. We believe
 that our audits provide a reasonable basis for our opinion.

 In our opinion, the financial statements present fairly, in all material
 respects, the net assets available for benefits of Jack Henry & Associates,
 Inc. 401(k) Retirement Savings Plan as of December 31, 2005 and 2004, and
 the changes in its net assets available for benefits for the year ended
 December 31, 2005, in conformity with accounting principles generally
 accepted in the United States of America.

 Our audits were conducted for the purpose of forming an opinion on the
 basic financial statements taken as a whole. The supplemental schedule is
 presented for the purpose of additional analysis and is not a required part
 of the basic financial statements but is supplementary information required
 by the Department of Labor's Rules and Regulations for Reporting and
 Disclosure under the Employee Retirement Income Security Act of 1974. The
 supplemental schedule is the responsibility of the Plan's management. The
 supplemental schedule has been subjected to the auditing procedures applied
 in our audit of the basic 2005 financial statements and, in our opinion, is
 fairly stated in all material respects in relation to the basic financial
 statements taken as a whole.

 JACK HENRY & ASSOCIATES, INC.
 401(k) RETIREMENT SAVINGS PLAN


 NOTES TO FINANCIAL STATEMENTS
 AS OF DECEMBER 31, 2005 AND 2004 AND FOR THE YEAR ENDED DECEMBER 31, 2005
 ----------------------------------------------------------------------------

 1. DESCRIPTION OF PLAN

    The following description of Jack Henry & Associates, Inc. 401(k)
    Retirement Savings Plan (the "Plan") provides only general information.
    Participants should refer to the Plan Agreement for a more complete
    description of the Plan's provisions.

    General-The Plan is a defined contribution, 401(k) plan covering
    employees of Jack Henry & Associates, Inc. (the "Company") who have
    attained the age of 18. To be eligible to receive the Company match
    and discretionary contribution employees must complete six months of
    service. The Company is the Plan Administrator and has appointed a
    trustee to hold and invest Plan assets. Diversified Investment Advisors
    is the Plan administrator and Investor's Bank and Trust is the Plan
    trustee. The Plan is subject to the Employee Retirement Income Security
    Act of 1974 ("ERISA"), as amended.

    Investments-Participants direct the investment of their contributions
    and employee contributions into various investment options offered by
    the Plan. The Plan currently offers Jack Henry & Associates, Inc. common
    stock, a money market fund, fourteen mutual funds, and a guaranteed
    separate account fund as investment options for participants.

    Contributions-Participants may contribute up to the maximum contribution
    allowable under section 401(k) of the Internal Revenue Code. The Company
    matches 100% of participant contributions up to a maximum match of the
    lessor of 5% of the participant's annual compensation or $5,000. The
    total amount which a participant could elect to contribute to the Plan
    on a pre-tax basis in 2005 could not exceed $14,000. However, in 2005,
    if a participant reached age 50 by December 31, 2005, they were able to
    contribute an additional $4,000 "catch up" contribution to the Plan on a
    pre-tax basis.

    In addition, the Company may make a special discretionary contribution.
    The amount of the discretionary contribution is determined by the
    Company. Participants must have 1,000 hours of service during the year
    to share in any discretionary contributions. There were no discretionary
    contributions in 2005.

    Vesting-Participants are immediately vested in their voluntary
    contributions, the employer's matching contribution and the earnings on
    these contributions. Vesting in the employer's discretionary portions of
    their accounts is based on years of continuous service with an employee
    vesting 20% after two years of service and subsequently vesting 20% each
    year until becoming fully vested with six years of continuous service.

    Benefits-Upon termination of service due to death, disability, or
    retirement, a participant may elect to receive a lump-sum amount equal
    to the value of his or her account at either the time of termination or
    at the end of the Plan year. An employee may also elect to receive the
    value of his or her account in installment payments or have the balance
    rolled over into an Individual Retirement Account.

    Participant Loans-Participants may borrow for qualifying reasons as
    defined in the Plan, from their fund accounts a minimum amount of $1,000
    up to a maximum of, the lesser of $50,000 less the amount of highest
    outstanding loan balance in the previous 12 months or 50% of their
    vested account balances. Loan terms range from one to five years, unless
    the loan is going to be used to purchase the participant's principal
    residence, in which case the term may extend beyond five years. The
    loans are secured by the balance in the participant's account and bear
    interest at a rate commensurate with local prevailing rates (ranging
    from 4.25% to 12.15% as of December 31, 2005), as determined by the
    Plan administrator. Principal and interest are paid through payroll
    deductions. Participants may elect to maintain their loan subsequent
    to their termination.

    Benefits Payable-Benefits are recorded when paid. As of December 31,
    2005 and 2004, distributions payable to Plan participants was zero.

    Forfeited Accounts-At December 31, 2005 and 2004, forfeited nonvested
    accounts totaled $14,600 and $5,934, respectively. These accounts will
    be used first as restoration of participant's forfeitures, then as
    offset to Plan expenses, then as a reduction to future discretionary
    contributions.

 2. SIGNIFICANT ACCOUNTING POLICIES

    Basis of Accounting-The financial statements of the Plan are prepared
    on the accrual basis.

    Investment Valuation and Income Recognition-Investments are stated
    at fair value, which is determined using public market quotations if
    available. Non-publicly traded investments (Diversified Investment
    Advisors-Managed Stability-Stable 5 Fund) have been reported based on
    values provided by the Plan trustee. Participant loans are reported at
    cost, which approximates fair value.

    The Plan invests in various securities including common stock and mutual
    funds. Investment securities, in general, are exposed to various risks,
    such as interest rate, credit, and overall market volatility. Due to the
    level of risk associated with certain investment securities, it is
    reasonably possible that changes in the values of investment securities
    will occur in the near term and that such changes could materially
    affect the amounts reported in the statements of net assets available
    for plan benefits.

    Purchases and sales of securities are recorded on a trade-date basis.
    Interest income is recorded on the accrual basis. Dividends are recorded
    on the ex-dividend date.

    Basis of Allocation-Investment income and gain or loss on investments
    are allocated to the participants based on the participant's account
    balance. Discretionary contributions, if any, are allocated based on
    eligible compensation. Unless directed otherwise by participants,
    employer matching and discretionary contributions will be allocated
    in the same manner as employee contributions.

    Use of Estimates-The preparation of financial statements in conformity
    with accounting principles generally accepted in the United States of
    America requires management to make estimates and assumptions that
    affect the reported amounts of net   assets available for benefits and
    changes therein. Actual results could differ from those estimates. The
    Plan utilizes various investment instruments. Investment securities, in
    general, are exposed to various risk, such as interest rate, credit, and
    overall market volatility. Due to the level of risk associated with
    certain investment securities, it is reasonably possible that changes in
    the values of investment securities will occur in the near term and that
    such changes could materially affect the amounts reported in the
    financial statements.

 3. INVESTMENTS

    The Plan's deposits are maintained in money market accounts until the
    deposits are allocated to the participant-directed funds based on the
    participant's percentage allocation election. The participant can elect
    direction of investments upon entering the Plan and may change the
    direction of investment options on a daily basis.

    The components of the Plan's individual investments which represent 5%
    or more of the Plan's net assets available for benefits at December 31,
    2005 and 2004, are as follows:

                                                         2005         2004
