Tax-advantaged retirement accounts, like IRAs and 401(k)s, help with tax planning by allowing you to contribute pre-tax income, which reduces your taxable income for the year. The growth in these accounts is tax-deferred, meaning you don’t pay taxes on the earnings until you withdraw in retirement. Roth accounts, on the other hand, let you contribute after-tax income, but qualified withdrawals are tax-free. These accounts provide valuable tools for managing your taxable income and reducing tax liabilities.
