| Meta Description | The basic actions that must be taken to establish a 401(k) plan. |
| Meta Canonical | null |
| Boilerpipe Text | When you establish a 401(k) plan you must take certain basic actions. For instance, one of your decisions will be whether to set up the plan yourself or consult a professional or financial institutionĀ - such as a bank, mutual fund provider, or insurance companyĀ - to help you establish and maintain the plan.
Initial actions
Here are four basic actions necessary to have a tax-advantaged 401(k) plan:
Adopt a written plan,
Arrange a trust fund for the planās assets,
Develop a recordkeeping system, and
Provide plan information to participants.
Adopt a written plan
Plans begin with a written document that serves as the foundation for day-to-day plan operations.Ā If you have hired someone to help with your plan, that person likely will provide it.Ā If not, consider obtaining assistance from a financial institution or retirement plan professional. In either case, you are bound by the terms of the plan document.
Before beginning a plan document, however, you will need to decide on the type of 401(k) plan that is best for youĀ - a traditional 401(k), a safe harbor 401(k), or a SIMPLE 401(k) plan.
A
traditional 401(k) plan
offers the maximum flexibility of the three types of plans.Ā Employers can choose to make contributions on behalf of all participants, match employeesā deferrals, or do both.Ā These contributions can be subject to a vesting schedule (which provides that an employeeās right to employer contributions becomes nonforfeitable only after a period of time).Ā In addition, a traditional 401(k) allows participants to make pre-tax contributions through payroll deductions.Ā Annual testing ensures that benefits for rank-and-file employees are proportional to benefits for owners/managers.
A
safe harbor 401(k) plan
is similar to a traditional 401(k) plan, but, among other things, must provide for employer contributions that are fully vested when made. However, the safe harbor 401(k) is not subject to many of the complex tax rules that are associated with a traditional 401(k) plan, including annual nondiscrimination testing.
An
automatic enrollment 401(k) plan
PDF
Ā allows an employer to automatically deduct a fixed percentage or amount from an employeeās wages and contribute that amount to the retirement plan unless the employee has affirmatively chosen to contribute nothing or a different amount. These automatic enrollment contributions qualify as
elective deferrals
.
Revenue Ruling 2009-30
PDF
demonstrates ways a 401(k) plan sponsor can include automatic contribution increases in its plan.
Notice 2009-65
PDF
provides sample automatic enrollment plan language that a 401(k) plan sponsor can adopt with automatic IRS approval.
The traditional, safe harbor and automatic enrollment 401(k) plans are for employers of any size and can be combined with other retirement plans.
A
SIMPLE 401(k) plan
was created so that small businesses could have an effective, cost-efficient way to offer retirement benefits to their employees.Ā A SIMPLE 401(k) plan is not subject to the annual nondiscrimination tests that apply to the traditional plans. Similar to a safe harbor 401(k) plan, however, the employer is required to make employer contributions that are fully vested.Ā This type of 401(k) plan is available to employers with 100 or fewer employees who received at least $5,000 in compensation from the employer for the preceding calendar year.Ā In addition, the employer canāt maintain any other retirement plans.
Once your have decided on the type of plan for your company, you will have flexibility in choosing some of the planās features -- such as which employees can contribute to the plan and how much.Ā Other features written into the plan are required by law.Ā For instance, the plan document must describe how certain key functions are carried out, such as how contributions are deposited in the plan.
Arrange a trust fund for the planās assets
A planās assets must be held in trust to assure that assets are used solely to benefit the participants and their beneficiaries.Ā The trust must have at least one trustee to handle contributions, plan investments, and distributions to and from the 401(k) plan.Ā Since the financial integrity of the plan depends on the trustee, this is one of the most important decisions you will make in establishing a 401(k) plan.Ā If you set up your plan through insurance contracts, the contracts do not need to be held in trust.
Develop a recordkeeping system
An accurate recordkeeping system helps track and properly attributeĀ contributions, earnings and losses, plan investments, expense and benefit distributions in participantsā accounts.Ā If you have a contract administrator or financial institution assist in managing the plan, that entity typically will help in keeping the required records. In addition, a recordkeeping system will help you, your plan administrator, or financial provider prepare the planās annual return/report that must be filed with the Federal government.
Provide plan information to employees
As you put your 401(k) plan in place, you must notify employees who are eligible to participate in the plan about your planās benefits and requirements.Ā A summary plan description, or SPD, is the primary vehicle to inform participants and beneficiaries about the plan and how it operates.Ā The SPD typically is created with the plan document.Ā You will need to send it to all plan participants.Ā In addition, you may want to provide your employees with information that emphasizes the advantages of joining your 401(k) plan. Employee perksĀ - such as pre-tax contributions to a 401(k) plan (or tax-free distributions in the case of Roth 401(k)s), employer contributions (if you choose to make them), and compounded tax-deferred earningsĀ - help highlight the advantages of participating in the plan. |

Here are four basic actions necessary to have a tax-advantaged 401(k) plan:
- Adopt a written plan,
- Arrange a trust fund for the planās assets,
- Develop a recordkeeping system, and
- Provide plan information to participants.
### Adopt a written plan
Plans begin with a written document that serves as the foundation for day-to-day plan operations. If you have hired someone to help with your plan, that person likely will provide it. If not, consider obtaining assistance from a financial institution or retirement plan professional. In either case, you are bound by the terms of the plan document.
Before beginning a plan document, however, you will need to decide on the type of 401(k) plan that is best for you - a traditional 401(k), a safe harbor 401(k), or a SIMPLE 401(k) plan.
A **traditional 401(k) plan** offers the maximum flexibility of the three types of plans. Employers can choose to make contributions on behalf of all participants, match employeesā deferrals, or do both. These contributions can be subject to a vesting schedule (which provides that an employeeās right to employer contributions becomes nonforfeitable only after a period of time). In addition, a traditional 401(k) allows participants to make pre-tax contributions through payroll deductions.

However, the safe harbor 401(k) is not subject to many of the complex tax rules that are associated with a traditional 401(k) plan, including annual nondiscrimination testing.
An **[automatic enrollment 401(k) plan PDF](https://www.irs.gov/pub/irs-pdf/p4674.pdf "1120 Publ 4674 (PDF)")** allows an employer to automatically deduct a fixed percentage or amount from an employeeās wages and contribute that amount to the retirement plan unless the employee has affirmatively chosen to contribute nothing or a different amount. These automatic enrollment contributions qualify as [elective deferrals](https://www.irs.gov/retirement-plans/plan-participant-employee/retirement-plans-definitions "Retirement plans definitions").

The traditional, safe harbor and automatic enrollment 401(k) plans are for employers of any size and can be combined with other retirement plans.
A **[SIMPLE 401(k) plan](https://www.irs.gov/retirement-plans/choosing-a-retirement-plan-simple-401k-plan "Choosing a retirement plan: SIMPLE 401k plan")** was created so that small businesses could have an effective, cost-efficient way to offer retirement benefits to their employees. A SIMPLE 401(k) plan is not subject to the annual nondiscrimination tests that apply to the traditional plans. Similar to a safe harbor 401(k) plan, however, the employer is required to make employer contributions that are fully vested. This type of 401(k) plan is available to employers with 100 or fewer employees who received at least \$5,000 in compensation from the employer for the preceding calendar year. In addition, the employer canāt maintain any other retirement plans.

Other features written into the plan are required by law. For instance, the plan document must describe how certain key functions are carried out, such as how contributions are deposited in the plan.
### Arrange a trust fund for the planās assets
A planās assets must be held in trust to assure that assets are used solely to benefit the participants and their beneficiaries. The trust must have at least one trustee to handle contributions, plan investments, and distributions to and from the 401(k) plan. Since the financial integrity of the plan depends on the trustee, this is one of the most important decisions you will make in establishing a 401(k) plan. If you set up your plan through insurance contracts, the contracts do not need to be held in trust.
### Develop a recordkeeping system
An accurate recordkeeping system helps track and properly attribute contributions, earnings and losses, plan investments, expense and benefit distributions in participantsā accounts. If you have a contract administrator or financial institution assist in managing the plan, that entity typically will help in keeping the required records. In addition, a recordkeeping system will help you, your plan administrator, or financial provider prepare the planās annual return/report that must be filed with the Federal government.
### Provide plan information to employees
As you put your 401(k) plan in place, you must notify employees who are eligible to participate in the plan about your planās benefits and requirements. A summary plan description, or SPD, is the primary vehicle to inform participants and beneficiaries about the plan and how it operates. The SPD typically is created with the plan document. You will need to send it to all plan participants. In addition, you may want to provide your employees with information that emphasizes the advantages of joining your 401(k) plan. Employee perks - such as pre-tax contributions to a 401(k) plan (or tax-free distributions in the case of Roth 401(k)s), employer contributions (if you choose to make them), and compounded tax-deferred earnings - help highlight the advantages of participating in the plan.

| Readable Markdown | When you establish a 401(k) plan you must take certain basic actions. For instance, one of your decisions will be whether to set up the plan yourself or consult a professional or financial institution - such as a bank, mutual fund provider, or insurance company - to help you establish and maintain the plan.
## Initial actions
Here are four basic actions necessary to have a tax-advantaged 401(k) plan:
- Adopt a written plan,
- Arrange a trust fund for the planās assets,
- Develop a recordkeeping system, and
- Provide plan information to participants.
### Adopt a written plan
Plans begin with a written document that serves as the foundation for day-to-day plan operations. If you have hired someone to help with your plan, that person likely will provide it. If not, consider obtaining assistance from a financial institution or retirement plan professional. In either case, you are bound by the terms of the plan document.
Before beginning a plan document, however, you will need to decide on the type of 401(k) plan that is best for you - a traditional 401(k), a safe harbor 401(k), or a SIMPLE 401(k) plan.
A **traditional 401(k) plan** offers the maximum flexibility of the three types of plans. Employers can choose to make contributions on behalf of all participants, match employeesā deferrals, or do both. These contributions can be subject to a vesting schedule (which provides that an employeeās right to employer contributions becomes nonforfeitable only after a period of time). In addition, a traditional 401(k) allows participants to make pre-tax contributions through payroll deductions. Annual testing ensures that benefits for rank-and-file employees are proportional to benefits for owners/managers.
A **safe harbor 401(k) plan** is similar to a traditional 401(k) plan, but, among other things, must provide for employer contributions that are fully vested when made. However, the safe harbor 401(k) is not subject to many of the complex tax rules that are associated with a traditional 401(k) plan, including annual nondiscrimination testing.
An **[automatic enrollment 401(k) plan PDF](https://www.irs.gov/pub/irs-pdf/p4674.pdf "1120 Publ 4674 (PDF)")** allows an employer to automatically deduct a fixed percentage or amount from an employeeās wages and contribute that amount to the retirement plan unless the employee has affirmatively chosen to contribute nothing or a different amount. These automatic enrollment contributions qualify as [elective deferrals](https://www.irs.gov/retirement-plans/plan-participant-employee/retirement-plans-definitions "Retirement plans definitions").
- [Revenue Ruling 2009-30 PDF](https://www.irs.gov/pub/irs-drop/rr-09-30.pdf "RR-2009-30") demonstrates ways a 401(k) plan sponsor can include automatic contribution increases in its plan.
- [Notice 2009-65 PDF](https://www.irs.gov/pub/irs-drop/n-09-65.pdf "n-09-65") provides sample automatic enrollment plan language that a 401(k) plan sponsor can adopt with automatic IRS approval.
The traditional, safe harbor and automatic enrollment 401(k) plans are for employers of any size and can be combined with other retirement plans.
A **[SIMPLE 401(k) plan](https://www.irs.gov/retirement-plans/choosing-a-retirement-plan-simple-401k-plan "Choosing a retirement plan: SIMPLE 401k plan")** was created so that small businesses could have an effective, cost-efficient way to offer retirement benefits to their employees. A SIMPLE 401(k) plan is not subject to the annual nondiscrimination tests that apply to the traditional plans. Similar to a safe harbor 401(k) plan, however, the employer is required to make employer contributions that are fully vested. This type of 401(k) plan is available to employers with 100 or fewer employees who received at least \$5,000 in compensation from the employer for the preceding calendar year. In addition, the employer canāt maintain any other retirement plans.
Once your have decided on the type of plan for your company, you will have flexibility in choosing some of the planās features -- such as which employees can contribute to the plan and how much. Other features written into the plan are required by law. For instance, the plan document must describe how certain key functions are carried out, such as how contributions are deposited in the plan.
### Arrange a trust fund for the planās assets
A planās assets must be held in trust to assure that assets are used solely to benefit the participants and their beneficiaries. The trust must have at least one trustee to handle contributions, plan investments, and distributions to and from the 401(k) plan. Since the financial integrity of the plan depends on the trustee, this is one of the most important decisions you will make in establishing a 401(k) plan. If you set up your plan through insurance contracts, the contracts do not need to be held in trust.
### Develop a recordkeeping system
An accurate recordkeeping system helps track and properly attribute contributions, earnings and losses, plan investments, expense and benefit distributions in participantsā accounts. If you have a contract administrator or financial institution assist in managing the plan, that entity typically will help in keeping the required records. In addition, a recordkeeping system will help you, your plan administrator, or financial provider prepare the planās annual return/report that must be filed with the Federal government.
### Provide plan information to employees
As you put your 401(k) plan in place, you must notify employees who are eligible to participate in the plan about your planās benefits and requirements. A summary plan description, or SPD, is the primary vehicle to inform participants and beneficiaries about the plan and how it operates. The SPD typically is created with the plan document. You will need to send it to all plan participants. In addition, you may want to provide your employees with information that emphasizes the advantages of joining your 401(k) plan. Employee perks - such as pre-tax contributions to a 401(k) plan (or tax-free distributions in the case of Roth 401(k)s), employer contributions (if you choose to make them), and compounded tax-deferred earnings - help highlight the advantages of participating in the plan. |
