Corporate Tax Rules For Mat
1. Overview of MAT
Minimum Alternate Tax (MAT) is a provision under Section 115JB of the Income Tax Act, 1961, designed to ensure that companies pay a minimum amount of tax even if they report zero or low taxable income due to exemptions, deductions, or losses.
Key Features:
Applies to all companies, including foreign companies operating in India.
Book profit is calculated as per accounting profit under Companies Act, adjusted for certain items to arrive at MAT.
MAT rate: 15% of book profit (plus surcharge and cess as applicable).
Carry forward of MAT credit: If MAT paid exceeds normal tax, excess can be carried forward for 15 years under Section 115JAA.
