Quick answer
DIY is usually cheapest if you know your state filing portal, have a usable address, and are comfortable reading state instructions. A filing service may be worth it if you want one checkout flow, registered agent options, reminders, and less form-hunting.
The state filing fee is not avoided either way. Whether you file yourself or use a service, the state still charges its required filing fee.
| Cost item | DIY filing | Filing service |
|---|---|---|
| State filing fee | Required | Required |
| Service fee | $0 if you file directly | Often low-cost to premium, depending on package |
| Registered agent | Optional only if you can serve or have another eligible agent | Often offered as an add-on or first-year bundle |
| EIN help | Free directly through the IRS | Often a paid convenience add-on |
When DIY makes sense
- You are forming in your home state and understand the state filing portal.
- You have a stable in-state address or registered agent plan.
- You want to keep service costs as low as possible.
- You are willing to track annual reports and state deadlines yourself.
When a filing service can be worth it
- You are a first-time founder and want a simpler process.
- You need a registered agent in the formation state.
- You want reminders for compliance deadlines.
- You prefer bundled documents such as an operating agreement template.
Some packages look cheap in year one because registered agent service or compliance features are discounted. Check the renewal price before buying.
What to avoid
Do not pay for items you can easily handle yourself unless the convenience is worth it. For example, the IRS EIN application is free when you apply directly.
Also avoid choosing a state only because a service provider promotes it. The cheapest state for marketing may not be the cleanest state for your real business operations.
Recommended path
Start by estimating state cost. Then decide whether you need registered agent service. If yes, compare filing-service bundles against buying registered agent service separately.
