The requirement to file a business income tax return depends on the type of business structure:

  • Companies, partnerships, and Limited Liability Partnerships (LLPs) must file a tax return regardless of profit or loss. Even if no operations were undertaken, a return is still required.
  • Companies, partnerships, and LLPs are taxed at a rate of 30%.

Deductions and Allowances

Businesses can leverage various deductions from their gross income to reduce taxable income, which includes:
