Understanding Tax on Lump Sum Payments

When you receive a lump sum payment, particularly from a qualified retirement account, there are several tax implications to consider. Here’s how to calculate the taxes:

  1. Federal Income Taxes: Determine your tax bracket based on your total income, including the lump sum. Apply this percentage to the lump sum to estimate the federal tax.
  2. State Income Taxes: Similar to federal taxes, apply your state’s income tax rate to the lump sum. This varies by state.
  3. Early Withdrawal Penalty: If you’re under 59.5 years and withdrawing from a qualified retirement account, add a 10% penalty to the taxable amount.

Using Deferred Annuity with GLWB

A more efficient option to manage taxes on a lump sum, especially from retirement accounts, is using a deferred annuity with a Guaranteed Lifetime Withdrawal Benefit (GLWB).

  • Spreads Taxes Over Years: This approach defers the tax liability, spreading it over several years instead of incurring a large tax bill in one year.
  • Guaranteed Income for Life: GLWB ensures a steady stream of income throughout your lifetime.
  • Lump Sum Death Benefit: Provides a lump sum to your beneficiaries upon your death.

Example Calculation

Suppose you receive a $50,000 lump sum from a retirement account at age 57. Assume you’re in a 22% federal tax bracket and your state tax rate is 5%.

  1. Federal Tax: $50,000 x 22% = $11,000
  2. State Tax: $50,000 x 5% = $2,500
  3. Early Withdrawal Penalty: $50,000 x 10% = $5,000
  4. Total Tax and Penalty: $11,000 (Federal) + $2,500 (State) + $5,000 (Penalty) = $18,500


Calculating tax on a lump sum requires considering federal and state taxes and any penalties for early withdrawal from retirement accounts. Opting for a deferred annuity with GLWB can be a tax-efficient strategy, providing lifelong income and tax spread. The total tax impact will depend on your specific tax bracket and state tax rates.
