                      SENIOR EXECUTIVE INCENTIVE BONUS PLAN

1.    Purpose

      This Senior Executive Incentive Bonus Plan (the "Incentive Plan") is
intended to provide an incentive for superior work and to motivate eligible
executives of DealerTrack Holdings, Inc. (the "Company") and its subsidiaries
toward even higher achievement and business results, to tie their goals and
interests to those of the Company and its stockholders and to enable the Company
to attract and retain highly qualified executives. The Incentive Plan is for the
benefit of Covered Executives (as defined below).

2.    Covered Executives

      From time to time, the Compensation Committee of the Board of Directors of
the Company (the "Compensation Committee") may select certain key executives
(the "Covered Executives") to be eligible to receive bonuses hereunder.

3.    Administration

      The Compensation Committee shall have the sole discretion and authority to
administer and interpret the Incentive Plan.

4.    Bonus Determinations

      (a) A Covered Executive may receive a bonus payment under the Incentive
Plan based upon the attainment of performance objectives which are established
by the Compensation Committee and relate to financial, operational or other
metrics with respect to the Company or any of its subsidiaries (the "Performance
Goals"), including but not limited to: (i) net income (loss) (either before or
after interest, taxes, depreciation and/or amortization), (ii) sales or revenue,
(iii) acquisitions or strategic transactions, (iv) operating income (loss), (v)
cash flow (including, without limitation, operating cash flow and free cash
flow), (vi) return on capital, (vii) return on assets (including, without
limitation, return on net assets), (viii) return on stockholders' equity, (ix)
economic value added, (x) stockholder returns, (xi) return on sales, (xii) gross
or net profit margin, (xiii) productivity, (xiv) expenses, (xv) margins, (xvi)
operating efficiency, (xvii) customer satisfaction, (xviii) working capital,
(xix) earnings (loss) per share, (xx) price per share of equity securities,
(xxi) market share, and (xxii) number of customers, any of which may be measured
either in absolute terms or as compared to any incremental increase or decrease,
or as compared to results of a peer group.

      (b) Except as otherwise set forth in this Section 4(b): (i) any bonuses
paid to Covered Executives under the Incentive Plan shall be based upon
objectively determinable bonus formulas that tie such bonuses to one or more
performance objectives relating to the Performance Goals, (ii) bonus formulas
for Covered Executives shall be adopted in each performance period by the
Compensation Committee and (iii) no bonuses shall be paid to Covered Executives
unless and until the Compensation Committee makes a certification with respect
to the attainment of the performance objectives. Notwithstanding the foregoing,
the Company may pay bonuses (including, without limitation, discretionary
bonuses) to Covered Executives under the Incentive

Plan based upon such other terms and conditions as the Compensation Committee
may in its discretion determine.

      (c) The payment of a bonus to a Covered Executive with respect to a
performance period shall be conditioned upon the Covered Executive's employment
by the Company on the last day of the performance period; provided, however,
that the Compensation Committee may make exceptions to this requirement, in its
sole discretion, including, without limitation, in the case of a Covered
Executive's termination of employment, retirement, death or disability.

5. Amendment and Termination

      The Company reserves the right to amend or terminate the Incentive Plan at
any time in its sole discretion. Any amendments to the Incentive Plan shall
require stockholder approval only to the extent required by any applicable law,
rule or regulation.

6. Stockholder Approval

      No bonuses shall be paid under the Incentive Plan unless and until the
Company's stockholders shall have approved the Incentive Plan. The Incentive
Plan will be submitted for the approval of the Company's stockholders after the
initial adoption of the Plan by the Board of Directors of the Company.

7. Term of Plan

      The Incentive Plan shall become effective as of May 26, 2005. The
Incentive Plan shall expire on the earliest to occur of: (a) the first material
modification of the Incentive Plan (as defined in Treasury Regulation Section
1.162-27(h)(1)(iii)); (b) the first meeting of the Company's stockholders at
which members of the Board of Directors of the Company are to be elected that

which occurred the first registration of an equity security of the Company under

date required by Section 162(m) of the Code and the rules and regulations
promulgated thereunder (including without limitation Treasury Regulation Section

                                                                   EXHIBIT 10.26

                           DEALERTRACK HOLDINGS, INC.

                      STOCK OWNERSHIP AND RETENTION PROGRAM

      This Stock Ownership and Retention Program of DealerTrack Holdings, Inc.
(the "Company") was adopted by the Company's Board of Directors (the "Board") on
May 26, 2005, to be effective upon the Public Trading Date (the "Effective
Date"). In the event that the Public Trading Date does not occur on or prior to
the first anniversary of the Effective Date, this Program will be void ab
initio.

      1.    PURPOSE

      It is the policy of the Board that each Covered Individual, consistent
with his or her responsibilities to the stockholders of the Company as a whole,
hold a significant equity interest in the Company.

      2.    SHARE OWNERSHIP AND RETENTION REQUIREMENTS

      (a) Minimum Share Requirement. The Board expects that all Covered
Individuals will make a good faith effort, depending on the circumstances, to
attain a level of Share ownership equal to the Minimum Share Requirement, as
applicable.

      (b) Counting. Shares that count toward the satisfaction of the Minimum
Share Requirement include Shares owned outright by the Covered Individual or by
his or her spouse or minor children, Shares held in trust for the benefit of the
Covered Individual or for the benefit of his or her spouse or minor children, or
Restricted Stock held pursuant to the DealerTrack Holdings, Inc. 2005 Incentive
Award Plan (the "2005 Incentive Plan") or other equity compensation plan of the
Company. Unexercised options (whether or not vested) or held pursuant to any
Company equity compensation plan will not count towards satisfaction of the
Minimum Share Requirement.

      3.    INITIAL COMPLIANCE, REPORTING AND RESTRICTIONS

      (a) Initial Compliance. Covered Individuals must attain a level of Share
ownership equal to the Minimum Share Requirement by the fifth (5th) anniversary
of the later of (i) the Effective Date or (ii) the date that such Covered
Individual commences services as an employee or director of the Company.

      (b) Reporting. Once in compliance with the Minimum Share Requirement, each
Covered Individual must sign an attestation, in such form as shall be provided
by the Company, that he or she has achieved the ownership requirement in
compliance with this Program.

      (c) Retention of Share Acquisitions. Until the Minimum Share Requirement
is achieved, and thereafter whenever the Minimum Share Requirement is not
complied with, a Covered Individual must retain twenty-five percent (25%) of all
Shares acquired by such Covered Individual pursuant to the exercise of a stock
option (net of Shares surrendered for payment, as applicable, of any option
exercise price and taxes). Once the Covered Individual achieves, and for so long
as such Covered Individual remains in compliance with, the Minimum

<PAGE>

Share Requirement, the Covered Individual does not need to comply with this
retention restriction.

      (d) Maintaining Share Ownership. Once a Covered Individual satisfies the
Minimum Share Requirement, such Covered Individual must continue to satisfy such
requirement for as long as he or she remains a Covered Individual.

      4.    COMPLIANCE AND ENFORCEMENT

      (a) Determination of Share Ownership. Each Covered Individual's
satisfaction of the Minimum Share Requirement will be determined annually as of
December 31st in any given year, subject to Section 3(a), by the Committee.

      (b) Enforcement of Minimum Share Requirement. At the sole discretion of
the Committee of the Board, a failure of a Covered Individual to satisfy the
Minimum Share Requirement may result in the reduction of, limitation in or
cancellation of Shares such Covered Individual shall receive in subsequent
grants or awards.

      (c) Exceptions. The Minimum Share Requirement and other requirements of
this Program may be waived, at the sole discretion of the Committee, for a
Covered Individual (i) if compliance would create severe hardship, (ii) if
compliance would prevent the Covered Individual from complying with a court
order, as in the case of a divorce settlement, or (iii) when such Covered
Individual attains the age of 62. A Covered Individual may file notice with the
Company's Secretary to be presented to the Committee, advising the Committee of
the circumstances and describing the extent of the waiver requested. It is
expected that these instances will be rare.

      5.    ADMINISTRATION OF THE PROGRAM

      (a) Authority. The Committee shall conduct the general administration of
the Program in accordance with its provisions. The Committee shall have full
power and authority to interpret the Program and to adopt such rules for the
administration, interpretation and application of the Program as are consistent
therewith and to interpret, amend or revoke any such rules. The Committee may
delegate administrative duties under the Program to one or more agents as it
shall deem necessary or advisable. Any decision or action taken by the Committee
with respect to the administration or interpretation of the Program shall be
conclusive and binding on all persons.

      (b) Liability. No member of the Board shall be personally liable for any
action or determination made in good faith with respect to the Program or to any
settlement of any dispute between a Covered Individual and the Company. The
Board shall be entitled to rely upon the advice, opinions or valuations of any
attorneys, consultants, accountants, appraisers, brokers or other persons.

      6.    AMENDMENT, MODIFICATION, AND TERMINATION

      This Program may at any time or from time to time be amended, modified or
terminated by the Board.
