Reduce Your Business Taxes with SECURE Act Tax Credits

The SECURE Act offers businesses the ability to establish a retirement plan and lower their tax liability. Your business may take advantage of retirement plan tax credits of up to $5,500 per year, which includes a $500 credit for implementing automatic enrollment in the plan, for three years, if you meet eligibility requirements. These startup tax credits go toward the costs of starting a new 401(k) plan as well as educating employees about the plan. Only new plans are eligible for these tax credits.

California Company Makes Retirement Plan a Fixture

With California mandating certain-sized companies offer a retirement plan for their employees, Plumbing M.D. embraced the opportunity and turned to Paychex.

"We feel like having the PEO partnership has helped us provide our employees with an experience that they probably won't get at other similar types of employers. That has been very helpful for retention and it's been a very positive and beneficial feature for everybody."

Retirement Services FAQs

  • What Are Retirement Services?

    What Are Retirement Services?

    Retirement services cover the full range of services needed over a plan’s life, particularly for a business or organization managing multiple plans. These can include plan design, investment, conversion, setup, enrollment, administration, and compliance testing.

  • What Is a 401(k) Retirement Plan?

    What Is a 401(k) Retirement Plan?

    A 401(k) retirement plan is a type of retirement account that allows employees to contribute a defined amount of pretax or Roth (after tax) dollars each pay period. Employers also have the opportunity to match part or all of the employee's tax-deferred retirement contributions, or provide a profit sharing contribution, although those contributions are not required. A 401(k) plan is a great option for entrepreneurs, small businesses, and large corporations to offer, particularly since pension plans are not as common as they once were and the future of Social Security benefits is unpredictable. Learn more about different types of retirement plans, 401(k) options, and 401(k) benefits.

  • What Are the Most Common Retirement Plans?

    What Are the Most Common Retirement Plans?

    Employers most commonly use 401(k) plans because of their flexible plan designs and the ability to save much more than other retirement plans such as IRAs.

  • What Are the Different Types of 401(k) Plans?

    What Are the Different Types of 401(k) Plans?

    There are many types of 401(k) retirement plans, with different rules that govern each: 

    • Traditional 401(k): An employer-sponsored retirement plan that allows employees to make pre-tax contributions via payroll deduction. Investment earnings and 401(k) contributions are tax-deferred until they are withdrawn. Businesses can choose to make matching or profit sharing employer contributions to the plan, although employer contributions are not required as part of a traditional 401(k) plan.
    • Safe Harbor 401(k): This plan exempts an employer from most annual nondiscrimination testing that is required with traditional 401(k) plans if the employer provides specific contributions to employees' accounts.
    • SIMPLE 401(k): Built specifically for small businesses with 100 employees or fewer, SIMPLE 401(k) plans are not subject to annual nondiscrimination testing that applies to traditional 401(k) plans. With this type of small business 401(k) retirement plan, the employer is required to make employer contributions that are fully vested.
    • Pooled Employer Plan: A professionally administered retirement plan that allows employers of any size to pool assets into a 401(k) plan. Since resources are pooled, there's reduced fiduciary liability, simplified plan administration for employers, and potential cost savings for participating employers.
    • 403(b): A tax-sheltered annuity or TSA plan offered by public education systems and certain 501(c)(3) tax-exempt organizations.

    There are pros and cons to each, but businesses tend to use 401(k) plans because they are flexible and enable employees to save more. A retirement specialist can review the different plan descriptions and help you decide which one is best for your business.
