Boston Capital Tax Credit Fund IV L.P.

(Name of registrant as specified in charter)

Has caused this notification to be signed on its behalf by the undersigned thereunto duly authorized.

Date: August 15, 2002	/s/ John P. Manning

ATTACHMENT TO FORM 12b-25

The results from operations for the quarters ended June 30, 2002 and 2001 will be significantly different because some of the Operating Partnerships formerly under construction or in lease-up are now at full operations. Estimating the statement of operations for those which we have not yet received information is not possible. Additionally, the Fund has continued to offer BAC's and acquire new Operating Partnerships. As of June 30, 2001 BAC's had been issued in Series 20 through 40, while BAC's have been issued in Series 41 and 42 since. We have been told that the missing Operating Partnership statements will be received over the next week, enabling the fund to file within the extension period.
