Figures are illustrations, not a quote. They assume a business owner with no employees who has worked in the business for at least ten years and earns enough to support the contribution. What you can contribute depends on your age, pay, years in business and other retirement plans.

Pay yourself first, then the IRS.

Money you put into the plan comes off this year’s taxable income. It sits in an account you control and is taxed when you take it out in retirement.

Explore the example plan

It’s your plan. We do the paperwork.

You are the plan administrator, which means you stay in charge of the plan and its money. We do the calculations, prepare every form the plan needs, and tell you when each one is due.

You

  • Decide how much to contribute within your range each year
  • Apply for your plan's tax ID (about ten minutes, we walk you through it)
  • Open the plan's brokerage account and choose the investments
  • Sign your plan documents and annual filings
  • Serve as plan administrator and trustee

Maxed

  • Design the plan and calculate your contribution range
  • Provide IRS pre-approved plan documents
  • Fill in your brokerage and tax ID paperwork for you to sign
  • Run the annual valuation, certified by an enrolled actuary
  • Prepare Form 5500-EZ and every other required filing, and remind you of each deadline

One price, everything included.

$2,499a year

$499 today to reserve your plan, refundable until you sign. The remaining $2,000 is due when your plan documents are ready. No setup fee, no charge per form, no percentage of your assets.

Get my estimate

Every year, that covers

  • Plan design and IRS pre-approved plan documents
  • Your contribution range, recalculated each year
  • Certification by an enrolled actuary
  • Form 5500-EZ and every other required filing, prepared for you
  • Pre-filled paperwork for your tax ID and brokerage account
  • Help from a person when you want it

Built for a business of one.

We only set up plans for businesses without employees. That keeps the rules simple and the price low. If that is not you yet, the estimate will say so and we will add you to the waitlist.

A good fit

  • You work for yourself: sole proprietor, LLC, S corporation, C corporation or partnership
  • The only people working in the business are owners and spouses
  • You earn more than you need to live on, and expect to for the next few years
  • You are already filling a 401(k) or SEP and want to put away more

Not yet

  • You have employees, or plan to hire in the next year or two
  • You own most of another business that has employees, or part of a firm your business works for
  • Your income swings so much that a required yearly contribution would be a strain

Questions

What is a cash balance plan?

It is a pension plan that your own business sponsors for you. Each year the plan credits your account with a contribution and with what the plan's investments earned, and the business takes a tax deduction for the money it puts in.

A 401(k) has a flat dollar cap on what goes in. A cash balance plan is capped by what may come out at retirement, so the closer you are to retirement, the more you are allowed to contribute each year.

Can I keep my Solo 401(k)?

Yes, and most people do. Your own salary deferrals are not affected. The employer profit-sharing contribution is generally limited to 6% of your pay in years when you also fund a cash balance plan.

Your estimate shows both plans together. We don't set up Solo 401(k) plans ourselves yet, but we account for yours in every calculation.

Is there still time to open a plan for 2026?

Yes. A new plan can be adopted for 2026 up to the due date of your business's 2026 tax return, including extensions, and funded by that same date.

If you run an S or C corporation, the benefit is based on the W-2 wages you were paid during 2026. Payroll cannot be changed after December 31, so it is worth getting your estimate while you can still adjust your salary.

What happens in a year when my income drops?

Each year you get a range with a minimum and a maximum. In a lean year you contribute the minimum. If the minimum itself is too much, the plan can be amended to reduce future benefits, frozen, or closed.

Timing matters: a change that lowers the benefit for a year usually has to be made early in that year. This is a real commitment, and it suits people who expect steady income for at least the next three to five years.

Where is my money held?

In a brokerage account that you open in the plan's name at Schwab or Fidelity. You are the trustee and the only person who can move money. If you connect the account, Maxed can read its value and holdings but can never move money.

When you retire or close the plan, the balance can usually be rolled into an IRA without tax.

How should the account be invested?

That is your decision as trustee. It helps to know how the plan works: your account is credited with the actual return on the plan's investments, gains and losses alike. When the money is paid out, it can never be less than the total of the pay credits made to your account; if losses take it below that, the business makes up the difference.

The rules also require the plan's investments to be diversified, so a single stock or cryptocurrency is out. Many owners invest plan money more conservatively than the rest of their savings. Maxed does not give investment advice.

What does being the plan administrator involve?

You are responsible for the plan, in the same way you are responsible for your tax return even when someone else prepares it. In practice it means reviewing and signing the documents and filings we prepare, filing them on time, and keeping copies.

We prepare everything the plan needs, including Form 5500-EZ once plan assets pass $250,000, and we remind you before each deadline.

Who checks the numbers?

Your contribution range is calculated by our software and then reviewed and certified by an independent enrolled actuary, a professional licensed by the federal government to sign pension valuations. The law requires that certification every year, and it is included in your fee.

What if I hire an employee later?

Once an employee meets the plan's age and service requirements they generally have to be covered, and the plan falls under rules we don't support yet. Tell us before you hire. We will help you either move the plan to a provider that handles employees or close it and roll your balance into an IRA.

Can I close the plan?

Yes. The IRS expects a plan to be set up with the intention of keeping it, so closing one after only a year or two without a business reason can raise questions. After a few years, or when your circumstances change, the plan can be terminated and the balance rolled over to an IRA.

Find your number for 2026.

You can open a plan for 2026 up to the day your tax return is due. If you pay yourself through payroll, your salary has to be set before December 31, so sooner is better.
