The budget related documents can be found in the website of Tamil Nadu government here.  The budget papers for this year have not been updated as yet in this site, but the budget speech can be read here. The webcast of the speech is available here.  The speech is conveiniently divided by sections, so incase you are interested in just one section (e.g. Tax, education, social welwafe, etc.), you can easily spot it and read your two or three paragraphs quickly.
