REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM



To the President and Chief Financial Officer

BCTC IV Assignor Corp.

We have audited the accompanying balance sheets of BCTC IV Assignor Corp. as of December 31, 2009 and 2008. These balance sheets are the responsibility of the Corporation'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 Corporation has determined that it is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audit 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 Corporation's internal control over financial reporting. Accordingly, we express no such opinion. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes 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 balance sheets referred to above present fairly, in all material respects, the financial position of BCTC IV Assignor Corp. as of December 31, 2009 and 2008 in conformity with accounting principles generally accepted in the United States of America.

December 31, 2009 and 2008











NOTE A - ORGANIZATION

BCTC IV Assignor Corp. (the "Corporation") was organized on October 12, 1993 under the laws of the State of Delaware to act as the assignor limited partner of, and to acquire and hold a limited partnership interest in, Boston Capital Tax Credit Fund IV L.P. (the "Limited Partnership"). The Corporation will assign units of beneficial interest in its limited partnership interest to persons who purchase Beneficial Assignee Certificates (BACs), on the basis of one unit of beneficial interest for each BAC. The Corporation will not have any interest in profits, losses or distributions on its own behalf.

NOTE B - INVESTMENT IN LIMITED PARTNERSHIP

On October 12, 1993, the Corporation was admitted as the assignor limited partner in Boston Capital Tax Credit Fund IV L.P. The Limited Partnership was formed to invest in real estate by acquiring, holding, and disposing of limited partnership interests in operating partnerships which will acquire, develop, rehabilitate, operate and own newly-constructed, existing or rehabilitated low-income apartment complexes. The Corporation has recorded its $100 investment at cost.

NOTE C - RECENT ACCOUNTING PRONOUNCEMENTS

In May 2009, the FASB issued guidance regarding subsequent events, which was subsequently updated in February 2010. This guidance established general standards of accounting for and disclosure of events that occur after the balance sheet date but before financial statements are issued or are available to be issued. In particular, this guidance sets forth the period after the balance sheet date during which management of a reporting entity should evaluate events or transactions that may occur for potential recognition or disclosure in the financial statements, the circumstances under which an entity should recognize events or transactions occurring after the balance sheet date in its financial statements, and the disclosures that an entity should make about events or transactions that occurred after the balance sheet date. This guidance was effective for financial statements issued for fiscal years and interim periods ending after June 15, 2009, and was therefore adopted by the Company for the quarter ended June 30, 2009. The adoption did not have a significant impact on the subsequent events that the Corporation reports, either through recognition or disclosure, in the financial statements. In February 2010, the FASB amended its guidance on subsequent events to remove the requirement to disclose the date through which an entity has evaluated subsequent events, alleviating conflicts with current SEC guidance. This amendment was effective immediately and therefore the Corporation did not include the disclosure in this Form 10-K.

NOTE C - RECENT ACCOUNTING PRONOUNCEMENTS - (continued)

In June 2009, the FASB issued the Accounting Standards Codification (Codification). Effective July 1, 2009, the Codification is the single source of authoritative accounting principles recognized by the FASB to be applied by non-governmental entities in the preparation of financial statements in conformity with GAAP. The Codification is intended to reorganize, rather than change, existing GAAP. Accordingly, all references to currently existing GAAP have been removed and have been replaced with plain English explanations of the Fund's accounting policies. The adoption of the Codification did not have a material impact on the Fund's financial position.
