This text explains how to use Form CT-1 X to correct employment tax errors on Form CT-1. The form is used for both underreported and overreported tax amounts, but the process depends on when the form is filed. Underreported tax amounts require the adjustment process, while overreported tax amounts may use either the adjustment or claim process if filed more than 90 days before the period of limitations expires. If filing within 90 days, both the adjustment and claim processes must be used.
Form CT-1 X requires information about the amount of COBRA premium assistance provided and the related Tier 1 Employer Medicare tax, as well as any nonrefundable credits used against the Tier 1 Employer Medicare tax that affect the calculation of the COBRA premium assistance credit.
You should file Form CT-1 X with the Connecticut Department of Revenue Services. You can file electronically through the BizFile Online system or by mailing a paper copy to the address provided in the form instructions.
The estimated average time to complete and file Form CT-1 X is approximately 5 hours, 38 minutes.
Form CT-1 X is an informational return filed with the Connecticut Department of Revenue Services to reconcile any adjustments made to the employer's quarterly unemployment tax returns (Forms CT-1). It reports various adjustments, such as nonrefundable credits and refundable credits, that affect the employer's Tier 1 Employer Medicare tax liability.
A nonrefundable credit reduces the amount of tax owed, but if the credit exceeds the tax liability, any excess is not refunded to the taxpayer. A refundable credit, on the other hand, reduces the amount of tax owed and may result in a refund to the taxpayer if the credit exceeds the tax liability.
Form CT1-X is one of Tax forms that are documents used to report information related to taxes to the relevant tax authority. There are various types of tax forms, including federal, state, and local tax forms, which can vary depending on the taxpayer's circumstances and location.
