Why a Low Cost 401k for Small Business Is Worth Getting Right

Finding a low cost 401k for small business is one of the smartest financial moves you can make as a business owner. It helps you attract and keep good employees, cut your tax bill, and build your own retirement at the same time.

Here are the most affordable 401(k) options available for small businesses right now:

The bottom line: Many small businesses can start a 401(k) for under $100 per month. And thanks to SECURE Act 2.0 tax credits, your net cost for the first three years could be close to zero.

But costs vary a lot depending on the fee model, plan type, and how many employees you have. Picking the wrong plan can mean paying far more than you need to.

Most business owners are surprised to learn that the real cost of a 401(k) is not just the monthly fee. There are investment fees, recordkeeping fees, and sometimes hidden administrative markups that quietly add up. Knowing what to look for before you sign up can save you thousands each year.

I'm Daniel Delaney, Founder of Seek & Find Financial, and throughout my career in financial services I've helped business owners navigate exactly these kinds of decisions, including finding the right low cost 401k for small business that fits their goals without overpaying. In the sections below, I'll walk you through how to compare plans, avoid common fee traps, and make the most of available tax incentives.

Understanding the Real Cost of a Small Business 401k

When you look for a retirement plan, you need to understand where the fees go. Setting up a plan is a big step. It is a key part of Retirement Savings Plans for Small Business Owners.

Many business owners only look at the setup fee. This is a mistake. A 401(k) plan has three main types of costs.

First, there are employer administration fees. These are the fees you pay to keep the plan running. They cover recordkeeping, compliance testing, and government reporting.

Second, there are employee participant fees. These are often monthly fees charged to each worker who joins the plan.

Third, there are investment fees. These are also called expense ratios. They are paid out of the money your employees invest. If these fees are too high, they will eat away at your employees' savings over time.

Flat-Fee vs Asset-Based Pricing Models

How you pay these fees matters. Providers usually charge you in one of two ways. They use flat fees or asset-based fees.

A flat-fee model means you pay a fixed dollar amount. It does not matter how much money is in the plan. You might pay $100 per month plus $5 per employee. This model is very predictable. As your business grows and your employees save more money, your fees stay the same.

An asset-based fee model is different. The provider takes a percentage of the total money saved in the plan. This is often called an Assets Under Management (AUM) fee. For example, they might charge 0.50% of all plan assets every year.

At first, an asset-based fee looks cheap. If your plan has $50,000 in it, a 0.50% fee is only $250 a year. But what happens when your team saves $1,000,000? That same 0.50% fee becomes $5,000 a year. The provider is not doing any extra work, but you are paying them much more money.

If you want a low cost 401k for small business, flat-fee models are usually the best choice for the long run. They keep your costs predictable.

Hidden Fees to Avoid in a Low Cost 401k for Small Business

You must look closely at the fine print. Some providers claim to be low cost but hide fees in other places.

Here are some common hidden fees to watch out for:

• Transaction Fees: Some plans charge employees every time they move money, take a loan, or change their investments.
• Termination Fees: You might have to pay a large fee if you decide to close the plan or move to a new provider.
• Form 5500 Filing Fees: Filing this annual tax form is required by law. Some providers charge extra to prepare and file it for you.
• Fund Markups: Some providers force you to use their own expensive mutual funds. They make money on these funds instead of charging you a clear administrative fee.

To keep your costs low, look for providers that offer transparent pricing. You can learn more about how these plans are managed by reading about the role of a 401k Plan Administrator.

How to Choose a Low Cost 401k for Small Business

Choosing a plan takes a few steps. You want a plan that fits your business size, budget, and goals. For business owners in Northwest Indiana places like Valparaiso, Chesterton, or Crown Point, as well as Chicago, this choice is a major part of your Small Business Owner Financial Planning.

Key Features of an Affordable Plan

An affordable plan should still have great features. You do not have to sacrifice quality to get a low price. Look for these key features:

• Seamless Payroll Integration: The plan should sync directly with your payroll provider. This includes systems like Gusto, ADP, or QuickBooks. When payroll runs, employee contributions should upload automatically. This saves you hours of manual work and prevents mistakes.
• Automated Compliance: The provider should handle annual compliance testing and IRS filings.
• 3(16) and 3(38) Fiduciary Support: A 3(16) fiduciary takes on the daily administrative liability. A 3(38) fiduciary takes on the investment liability. Having these services protects you from legal mistakes.
• Easy Online Portals: Both you and your employees should have simple dashboards to track savings and change settings.

Comparing Contribution Limits and Matching Options

A 401(k) plan offers much higher saving limits than other retirement accounts.

For 2025:

• Employees can contribute up to $23,500 per year.
• If they are 50 or older, they can make a catch-up contribution of $7,500, for a total of $31,000.
• The total limit for all contributions (employee plus employer) is $70,000 (or $77,500 if age 50+).

For 2026:

• Employees can contribute up to $24,500 per year.
• The catch-up limit for age 50 and older is $8,000.
• The total combined contribution limit is $72,000 (or $80,000 with catch-up).

As an employer, you can choose how to match employee savings. You can offer a matching contribution, like matching 100% of what they save up to 3% of their pay. Or you can make a non-elective contribution, where you give every eligible employee a set percentage of their pay, even if they do not save any of their own money.

You can also set a vesting schedule. Vesting determines when employees fully own the matching money you give them. With immediate vesting, they own it right away. With a graded or cliff vesting schedule, they must work for you for a certain number of years before they own the match. This is a great tool to keep your best workers.

Maximizing Tax Credits and Benefits under SECURE Act 2.0

The SECURE Act 2.0 makes starting a 401(k) incredibly cheap. The federal government wants small businesses to offer retirement plans, so they are paying for a large portion of the costs. This is highly beneficial for business owners looking at Retirement Plans for High Earners.

Here are the main tax credits available for businesses with 50 or fewer employees:

1. The Startup Tax Credit: This credit covers 100% of your qualified startup and administration costs for the first three years. You can claim up to $5,000 per year, for a total of $15,000.
2. The Auto-Enrollment Credit: If you add an automatic enrollment feature to your new plan, you get an extra $500 per year for three years. That is another $1,500 in tax credits.
3. The Employer Contribution Credit: The government will help pay for the matching contributions you make to your employees. For businesses with up to 50 employees, you can get a tax credit of up to $1,000 per eligible employee annually for the first five years. This credit slowly phases out over five years.

If you add these up, a small business with ten employees could get up to $16,500 in administrative tax credits over three years, plus thousands more to offset the cost of matching contributions.

Safe Harbor Plans for Simplified Compliance

Standard 401(k) plans must pass strict IRS nondiscrimination tests every year. These tests make sure that business owners and high earners do not save way more than their everyday employees. If your plan fails these tests, the IRS can force you to return contributions or pay penalties.

A Safe Harbor 401(k) Plans | Simplify Compliance & Save More plan is a fantastic way to avoid this headache.

By offering a mandatory contribution to your employees, your plan automatically passes these annual tests. This allows business owners and high earners to maximize their personal savings up to the full limit without worry.

To get safe harbor status, you must choose one of these contribution options:

• Basic Match: Match 100% of employee contributions up to 3% of their pay, plus 50% of the next 2% of their pay.
• Enhanced Match: Match 100% of employee contributions up to 4% of their pay.
• Non-Elective Contribution: Give 3% of pay to every eligible employee, whether they save money or not.

All safe harbor contributions must be 100% vested immediately.

Alternative Low Cost 401k for Small Business Options

If a traditional or safe harbor 401(k) still feels too complex, there are other low-cost options you can consider.

• SIMPLE IRA: This is a great option for businesses with fewer than 100 employees. It has lower administrative costs and no annual Form 5500 filing. However, the contribution limits are lower. For 2025, the employee contribution limit is $16,500. For a deep dive, read our Simple IRA Complete Guide 2026.
• SEP IRA: A SEP IRA is very easy to set up. Only the employer can contribute to this plan. You can contribute up to 25% of an employee's pay, up to a maximum of $70,000 for 2025. It is highly flexible because you do not have to contribute every year. This is ideal if your business cash flow goes up and down.
• Solo 401(k): If you are self-employed and have no employees other than your spouse, a Solo 401(k) is often the best choice. It gives you the high contribution limits of a standard 401(k) without the complex compliance testing.

Frequently Asked Questions About Small Business 401ks

What is the cheapest 401k option for a very small business?

The cheapest option is usually a digital-first 401(k) provider like 401GO or Gusto/Guideline. These platforms use modern technology to automate recordkeeping and compliance. This keeps their costs very low. For example, 401GO's starter plan costs just $25 per month plus $2 per participant. If you have no employees, a Solo 401(k) from a provider like Fidelity is often free of administrative fees.

How do tax credits offset the cost of starting a 401k?

Under the SECURE Act 2.0, the government offers tax credits that directly reduce the taxes you owe. The startup credit covers 100% of your administrative fees up to $5,000 per year for the first three years. This means if your provider charges you $1,200 a year to run the plan, your tax bill is reduced by $1,200. Your net out-of-pocket cost for running the plan becomes $0.

Can a business owner contribute to their own small business 401k?

Yes. As a business owner, you are also an employee of your company. You can make elective deferrals up to the annual limit. You can also receive the same matching contributions that you offer to your team. If you set up a safe harbor plan, you can maximize your personal savings without worrying about nondiscrimination testing.
