The employer bears the ultimate responsibility for complying with their contribution obligation, even if they use a third-party administrator to act on their behalf. Interest and penalties for late or missed payments will be assessed against the employer.
To verify that your third-party administrator is complying with your contribution obligation, sign in to your My Account and view your filing history. If you do not see an invoice and payment in COMPLETED status, contact your third-party administrator for a status update.
If you have not already registered, register your business.
