What is the cost of an amendment?

The standard fees for amendments can be found in Namely's Add-On Pricing Guide.

Please note that most states have two returns to file per quarter: 1) a withholding return and 2) an unemployment return. If both returns need to be amended for a single quarter, the fee would only reflect the 
cost of the amendment.

Note: The example above does not include the additional fee per hour.

If the amendments cover previous quarters, the fee depends on how many quarters the amendment goes back; for example, if you were amending a state with both returns mentioned above for the previous three quarters, the fee would be 3 x cost of the amendment.

Note: The example above does not include the additional fee per hour.
