A West Coast insurer is promoting use of a new retirement savings tool.

Pacific Life Insurance Company, Newport Beach, Calif., has started offering a Roth 401(k) option within its Individual(k) retirement plan program for small businesses.

The Roth 401(k) program gives participants a chance to contribute to retirement accounts with income that has already been taxed. Some taxpayers are interested in the program because the government is promising not to impose additional income taxes once participants begin drawing on the accounts for retirement income.

In addition, contribution limits are higher for Roth 401(k) contributions than for Roth individual retirement account options, and taxpayers can participate in the Roth 401(k) program even if their incomes exceed the income maximum for the Roth IRA program, Pacific Life says.

The Pacific Life Roth 401(k) program offers participants access to 5 asset-allocation funds.

A unit of BISYS Group Inc., Roseland, N.J., will handle recordkeeping and administrative services.
