Organization

BCTC IV Assignor Corp., a Delaware corporation (the "Assignor Limited Partner") was formed for the sole purpose of serving as an assignor for Boston Capital Tax Credit Fund IV L.P. (the "Fund") and will not engage in any other business. Units of beneficial interest in the limited partnership interest of the Assignor Limited Partner will be assigned by the Assignor Limited Partner by means of beneficial assignee certificates ("BACs") to investors and investors will be entitled to all the rights and economic benefits of a limited partner of the Fund, including rights to a percentage of the income, gains, losses, deductions, credits and distributions of the Fund. The Assignor Limited Partner is wholly-owned by John P. Manning.

A Registration Statement on Form S-11 and the related prospectus, as supplemented (the "Prospectus") were filed with the Securities and Exchange Commission and became effective December 16, 1993 in connection with a public offering ("Offering") in one or more series of a minimum of 250,000 BACs and a maximum of 30,000,000 BACs at $10 per BAC.

On April 2, 1998 an amendment to Form S-11, which registered an additional 25,000,000 BACs for sale to the public in one or more series, became effective. On August 31, 1999 an amendment to Form S-11, which registered an additional 8,000,000 BACs for sale to the public became effective. On July 26, 2000 an amendment to Form S-11, which registered an additional 7,500,000 BACs for sale to the public became effective. On July 23, 2001 an amendment to Form S-11, which registered an additional 7,000,000 BACs for sale to the public became effective.

As of December 31, 2013, subscriptions had been received and accepted by the General Partner in Series 20, Series 21, Series 22, Series 23, Series 24, Series 25, Series 26, Series 27, Series 28, Series 29, Series 30, Series 31, Series 32, Series 33, Series 34, Series 35, Series 36, Series 37, Series 38, Series 39, Series 40, Series 41, Series 42, Series 43, Series 44, Series 45 and Series 46 for 83,651,080 BACs representing capital contributions of $836,177,880.

Description of Business

The Assignor Limited Partner's sole purpose is to act as a conduit through which all of the economic and tax benefits of an investment in the Fund are passed along to the investor BAC holders. The Assignor Limited Partner does not charge any fees for its services and has no income.

The Fund's principal business is to invest as a limited partner in other limited partnerships (the "Operating Partnerships") each of which will own or lease and will operate an apartment complex exclusively or partially for low- and moderate-income tenants. Each Operating Partnership in which the Fund will invest will own apartment complexes which are completed, newly-constructed, under construction or rehabilitation, or to-be constructed or rehabilitated, and which are expected to receive government assistance. Each apartment complex is expected to qualify for the low-income housing tax credit under Section 42 of the Internal Revenue Code (the "Federal Housing Tax Credit"), providing tax benefits over a period of ten to twelve years in the form of tax credits which investors may use to offset income, subject to strict limitations, from other sources. Some apartment complexes may also qualify for the historic rehabilitation tax credit under Section 47 of the Internal Revenue Code (the "Rehabilitation Tax Credit"). Section 236 (f) (ii) of the National Housing Act, as amended, and of the Housing and Urban Development Act of 1965, as amended, each provide for the making by The Department of Housing and Urban Development ("HUD") of rent supplement payments to low income tenants in properties which receive other forms of federal assistance such as tax credits. The payments for each tenant, which are made directly to the owner of their property, generally are in such amounts as to enable the tenant to pay rent equal to 30% of the adjusted family income. Some of the apartment complexes in which the Fund has invested are receiving such rent supplements from HUD. HUD has been in the process of converting rent supplement assistance to assistance paid not to the owner of the apartment complex, but directly to the individuals. At this time, the Fund is unable to predict whether Congress will continue rent supplement programs payable directly to owners of the apartment complex.

As of December 31, 2013, the Fund has investments in 8 Operating Partnerships on behalf of Series 20, 4 Operating Partnership on behalf of Series 21, 9 Operating Partnerships on behalf of Series 22, 11 Operating Partnerships on behalf of Series 23, 8 Operating Partnerships on behalf of Series 24, 7 Operating Partnerships on behalf of Series 25, 24 Operating Partnerships on behalf of Series 26, 10 Operating Partnerships on behalf of Series 27, 19 Operating Partnerships on behalf of Series 28, 17 Operating Partnerships on behalf of Series 29, 16 Operating Partnerships on behalf of Series 30, 24 Operating Partnerships on behalf of Series 31, 14 Operating Partnerships on behalf of Series 32, 8 Operating Partnerships on behalf of Series 33, 13 Operating Partnerships on behalf of Series 34, 10 Operating Partnerships on behalf of Series 35, 9 Operating Partnerships on behalf of Series 36, 7 Operating Partnerships on behalf of Series 37, 10 Operating Partnerships on behalf of Series 38, 9 Operating Partnerships on behalf of Series 39, 16 Operating Partnerships on behalf of Series 40, 19 Operating Partnerships on behalf of Series 41, 21 Operating Partnerships on behalf of Series 42, 23 Operating Partnerships on behalf of Series 43, 9 Operating Partnerships on behalf of Series 44, 29 Operating Partnerships on behalf of Series 45 and 15 Operating Partnerships on behalf of Series 46.

The business objectives of the Fund are to:
(1)	provide current tax benefits to investors in the form of Federal Housing Tax Credits and, in limited instances, a small amount of Rehabilitation Tax Credits, which an investor may apply, subject to various strict limitations, against the investor's federal income tax liability from active, portfolio and passive income;
(2)	preserve and protect the Fund's capital and provide capital appreciation and cash distributions through increases in value of the Fund's investments and, to the extent applicable, equity buildup through periodic payments on the mortgage indebtedness with respect to the apartment complexes;
(3)	provide tax benefits in the form of passive losses which an investor may apply to offset his passive income (if any); and
(4)	provide cash distributions (except with respect to the Fund's investment in some non-profit Operating Partnerships) from capital transaction proceeds. The Operating Partnerships intend to hold the apartment complexes for appreciation in value. The Operating Partnerships may sell the apartment complexes after a period of time if financial conditions in the future make sales desirable and if sales are permitted by government restrictions.

Item 9.	Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

Item 9A.	Controls and Procedures
(a)	Evaluation of Disclosure Controls and Procedures
	As of the end of the period covered by this report, the Assignor Limited Partner, under the supervision and with the participation of the Principal Executive Officer and Principal Financial Officer, carried out an evaluation of the effectiveness of the Assignor Limited Partner's "disclosure controls and procedures" as defined in the Securities Exchange Act of 1934 Rules 13a-15 and 15d-15. Based on that evaluation, the Assignor Limited Partner's Principal Executive Officer and Principal Financial Officer have concluded that as of and for the year ended December 31, 2013, the Assignor Limited Partner's disclosure controls and procedures were adequate and effective in timely alerting them to material information relating to the Assignor Limited Partner required to be included in the Assignor Limited Partner's periodic SEC filings.
(b)	Management's Annual Report on Internal Control over Financial Reporting
	Management of the Assignor Limited Partner is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act). The Assignor Limited Partner's internal control system over financial reporting is designed to provide reasonable assurance to the Assignor Limited Partner's management regarding the reliability of financial reporting and the preparation of financial statements for external purposes of accounting principles generally accepted in the United States. Due to inherent limitations, an internal control system over financial reporting may not prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance of achieving their control objectives. The Assignor Limited Partner's management, under the supervision and with the participation of the Principal Executive Officer and Principal Financial Officer, assessed the effectiveness of the Assignor Limited Partner's internal controls and procedures over financial reporting as of December 31, 2013. In making this assessment, the Assignor Limited Partner's management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control - Integrated Framework. Based on this assessment, management believes that, as of December 31, 2013, the Assignor Limited Partner's internal control over financial reporting was effective.
(c)	Changes in Internal Controls
	There were no changes in the Assignor Limited Partner's internal control over financial reporting that occurred during the quarter ended December 31, 2013 that materially affected, or are reasonably likely to materially affect, the Assignor Limited Partner's internal control over financial reporting.

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, 2013 and 2012. BCTC IV Assignor Corp.'s management is responsible for these financial statements. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the 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 balance sheets are free of material misstatement. The Corporation 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 Corporation'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 statements presentation. We believe that our audits of the balance sheets provide a reasonable basis for our opinion.

In our opinion, based on our audits, the financial statements referred to above present fairly, in all material respects, the financial position of BCTC IV Assignor Corp. as of December 31, 2013 and 2012 in conformity with accounting principles generally accepted in the United States of America.
