What is a key tax feature of the cash value growth inside a permanent life insurance policy?

The cash value in a permanent life insurance policy generally grows on a tax-deferred basis, meaning the policyowner does not pay income tax on the gains as they accumulate inside the policy. Taxes may apply later depending on how the value is accessed: withdrawals up to the cost basis (premiums paid) are typically tax-free, while gains withdrawn beyond basis can be taxable, and policy loans are generally not taxed unless the policy lapses or is surrendered. This tax-deferred growth is a notable advantage of permanent insurance. (Tax treatment can change and depends on individual circumstances, so this is the general rule.)
