What is Tax Deferral?

Tax deferral allows a taxpayer to delay recognizing income or paying taxes until a future period, typically upon withdrawal or sale. The primary benefit is compounding: money that would have been paid in taxes continues to grow in the account. Common tax-deferred vehicles include traditional 401(k) and 403(b) plans, traditional IRAs, deferred annuities, and deferred compensation plans. When funds are eventually withdrawn, they are taxed as ordinary income. Tax deferral differs from tax exemption—deferred taxes are eventually owed, whereas tax-exempt income is never taxed.

Example

Example

An investor contributes $10,000 to a traditional 401(k) annually over 30 years, earning a 7% average annual return. Without deferral, taxes reduce each year's growth. With tax deferral, the full $10,000 compounds to roughly $944,000 before withdrawal—compared to approximately $712,000 after a 25% annual drag on returns—illustrating the powerful compounding benefit of deferral.
