It is illegal to evade taxes in India, and the government has measures in place to detect and prosecute tax evaders. However, there are ways in which the wealthy may minimize their tax liabilities through legitimate means, such as taking advantage of tax exemptions and deductions, investing in tax-friendly instruments, and structuring their financial affairs in a tax-efficient manner.

Additionally, some wealthy individuals may resort to illegal means such as hiding their income, misreporting their income, or evading taxes by shifting their wealth offshore or through shell companies. The government has enacted laws and regulations to detect and penalize such activities, but enforcing these laws can be challenging.

In conclusion, tax avoidance is different from tax evasion, and individuals should always make sure that their financial affairs are in compliance with the law.
