Forty-one sections on deduction and collection at source, advance tax, and recovery — the chapter with the most compliance deadlines in the Act.
Sections 390 to 402 carry TDS and TCS: section 393 is the single consolidated deduction section that absorbs what the 1961 Act spread across sections 192 to 195, section 394 collection at source, section 395 certificates, section 397 compliance and reporting, and section 398 the consequences of failure. Sections 403 to 411 carry advance tax. Sections 412 to 422 carry recovery, including the Tax Recovery Officer, other modes of recovery and recovery in pursuance of agreements with foreign countries. Sections 423 to 430 carry interest and fees for default.
