Identify the service being purchased
An owner may use the phrase “payroll company” for a software platform, a reporting agent, a professional employer organization or an agent appointed through Form 2678. These arrangements are not interchangeable. Before signing a service agreement, ask the provider to identify its legal role and the forms it will file. A dashboard that says taxes are handled does not reveal whose EIN will appear on the return or who remains responsible if a deposit fails.
The IRS Form 2678 instructions describe a request for approval to appoint an agent for specified employment-tax duties. Approval and the scope of the appointment matter. The business should keep the actual authorization record with its payroll setup documents, rather than assuming that paying a provider’s invoice created an approved federal tax agency relationship.
Trace a sample payroll from start to finish
Suppose the corporation authorizes a $20,000 gross owner payroll. Employee deductions total $5,000 and employer taxes total $1,500 in this hypothetical, leaving $15,000 of employee net pay and $6,500 of combined tax funding. If the provider withdraws $21,500, the company should be able to trace that withdrawal into a $15,000 payment and $6,500 assigned to the proper tax accounts. A single withdrawal confirmation proves only that cash left the bank.
Ask for a sample reconciliation that identifies the return period, deposit date, tax type and reporting EIN for each amount. If the provider instead collects $22,000 because it includes a $500 service fee, the fee should remain visible. Do not reconcile tax funding by treating every difference as payroll expense. The owner needs enough information to distinguish compensation, withheld funds, employer taxes and the provider’s compensation.
Make the authorization file usable
Retain the signed appointment request, approval evidence, service agreement and list of covered tax forms. Record the effective date and identify payroll periods outside the appointment. If the owner adds household payroll, a different corporation or another payment type, ask whether the existing authorization covers that work. The convenience of a shared login does not extend the legal appointment. Give the bookkeeper a concise scope sheet so that a new employee does not send unrelated returns to the wrong party.
Specify who supplies wage information, who approves payroll, who monitors notices, and who can view deposit confirmations. Require prompt notice of failed withdrawals or rejected submissions. A provider cannot correct missing cash by filing an otherwise accurate return. Likewise, an employer cannot assume that a bank transfer satisfied a deposit if the provider applied it to another client period. Build an exception procedure that identifies the specific liability and directs the correction to the proper account.
Reconcile the employer’s continuing exposure
Have the responsible person compare the provider’s reports with the company’s wage ledger at least quarterly. Review the reporting arrangement against the applicable IRS rules rather than assuming all employer liability shifted to the provider. Access to tax-account information should be part of the operating setup, not something requested only after the provider stops responding. A founder who signs paychecks but never sees notices may discover a mismatch long after the underlying cash was available.
Keep compensation approval separate from filing authorization. The agent may process the owner’s salary, but it does not establish reasonable compensation, classify a shareholder distribution or approve a reimbursement policy. Send clear earning codes and supporting instructions. If a taxable benefit is entered through an ordinary cash-pay code, the resulting error can survive even when the agent files every form on time. Accurate source instructions remain an employer task.
Plan termination before switching providers
When changing arrangements, assign the last payroll date, final deposit responsibility, year-end wage statements and any correction work. Determine whether a revocation or replacement appointment is needed and preserve proof of its effective date. The old provider’s termination invoice and the IRS authorization timeline may differ. Do not allow both providers to file the same period because each believes it owns the entire year. Keep one transition ledger showing wages and deposits by responsible filer.
The useful outcome is a verifiable chain from compensation authorization to employee payment and tax reporting. This article does not resolve every kind of payroll outsourcing arrangement, establish that a particular provider qualifies as an agent, or promise release from employer liability. Those questions require the approved documents and governing procedure. If a provider cannot explain the role it performs, resolve that uncertainty before giving it additional payroll funding or assuming it will answer government notices.
