Social Security Solvency and Modernization Act of 2003 - Amends title II (Old Age, Survivors and Disability Insurance) (OASDI) of the Social Security Act (SSA) to require the Personal Retirement Account Board to: (1) establish a federally-administered personal retirement account (PRA) for each eligible individual in the Personal Retirement Account Fund (PRAF); and (2) credit to the eligible individual's PRA the contributions transferred from the Federal Old-Age and Survivors Insurance Trust Fund (Trust Fund) that result from reduced Federal Insurance Contributions Act (FICA) tax rates (provided for in this Act), as well as other specified contributions involving certain tax overpayments treated as contributions and certain rollovers. Requires investment of a PRA in a manner similar to that under the Thrift Savings Plan for Federal employees.

Establishes in the Treasury a Personal Retirement Account Fund composed of all established PRAs, and managed by a Personal Retirement Account Board established in the Social Security Administration.

Provides for an alternative PRA privately-administered by a certified investment firm, credit union, insurance company, or other certified institution.

Prescribes rules for: (1) distribution of an eligible individual's PRA's funds; (2) off-budget treatment of the PRAF and any federally-administered PRAs within it; and (3) privately-administered PRAs.

Amends the Internal Revenue Code to reduce FICA tax rates on the income of every eligible individual, and to impose a PRA contribution on such income, to be credited to the eligible individual's PRA. Entitles each qualified eligible individual to a specified limited PRA tax credit for the taxable year involved, treated as a tax overpayment, to be transferred by the Secretary of Health and Human Services for crediting by the Commissioner of Social Security, as a contribution equal to the tax overpayment, to such eligible individual's PRA.

Establishes the Commission on the Review of Federal Agencies and Programs to evaluate all agencies and programs and recommend to Congress realignment or elimination of any that has wasted Federal funds.
