Some steps in Atto Payroll require a company signatory — an individual authorized by the IRS to sign official documents on behalf of your business.
Your business structure determines who can serve in this role. Below are general IRS guidelines for selecting the correct signer:
Who Can Sign Based on Business Type
Sole Proprietorship
The individual who owns the business.
Corporation (including LLCs treated as corporations)
An officer with legal authority to bind the corporation.
A person designated by the board of directors.
An officer or employee authorized by a principal officer.
Anyone authorized to access IRS tax information for the company.
Partnership (including LLCs treated as partnerships) or Unincorporated Organization
Any member of the organization during the tax period covered by the form.
Single Member LLC (treated as a disregarded entity)
The individual who owns the LLC.
Trust or Estate
The fiduciary overseeing the trust or estate.
Why This Matters
The signer’s job title and legal authority must match what’s declared in your Atto Payroll setup. If the signer is not correctly identified, your authorization documents may be rejected, causing delays in payroll processing.
