To save on taxes, invest in tax-advantaged accounts like retirement accounts (401(k), IRA, EPF, PPF) and Health Savings Accounts (HSAs). Utilize deductions and credits, such as standard/itemized deductions and education credits. Invest in tax-efficient vehicles like tax-free bonds or Equity-Linked Savings Schemes (ELSS). Optimize capital gains by holding investments long-term and offsetting gains with losses. Use Flexible Spending Accounts (FSAs) for pre-tax healthcare expenses.
