Linking PAN with Aadhaar is now compulsory for most taxpayers because the Indian government has introduced this requirement to simplify the tax system and curb tax evasion. This linkage ensures that a taxpayer’s identity is verified through two major documents. Aadhaar, being a biometric-based ID, helps the government make sure that no fraudulent PAN cards are being used for financial transactions. This bolsters the tax system's security.
Linking PAN with Aadhaar also makes sense from an administrative viewpoint, as these documents consolidate various records under a single identity. This makes it easier for the government to monitor financial activities.
What’s in it for you? You experience fewer discrepancies and errors when filing tax returns. Moreover, if you fail to link Aadhaar with PAN, you might end up with an inactive PAN card, which will impact your ability to open bank accounts, invest in mutual funds, or file tax returns.
