The clock that starts on the hire date, not the first paycheck

Hiring starts three clocks at once in Detroit: I-9 verification, new-hire reporting to Illinois, and the first deposit for that employee. The reporting deadline and its penalty are below with the state source.

Two free marketplace paths: one form brings back multiple vetted payroll providers who know they are competing for the account.

Illinois requires new hires to be reported to the state directory Within 20 days of hire date, a clock that starts on the hire date rather than the first payroll - which is exactly why fast-hiring Detroit employers miss it.

The county around Detroit holds 349 business establishments, of which 315 employ fewer than 20 people - the size band where payroll is bought as a service rather than staffed, per Census County Business Patterns 2023.

Detroit, Illinois has about 74 residents, and its payroll costs are set by headcount, pay frequency and state rules rather than by geography - the list price is national; the compliance bill is local.

Compliance paperwork is the part of payroll that providers automate best and buyers evaluate least. Ask exactly which filings a provider makes on your behalf in Illinois - new-hire reports, state withholding, unemployment wage reports - and which ones stay on your desk.

Hiring in Detroit starts three clocks: Form I-9 verification, new-hire reporting to Illinois's directory, and the first payroll deposit for that employee. The reporting deadline is the one owners miss, because it runs from the hire date rather than from the first paycheck.

What a provider files - and what stays with you

  • Ask which returns the provider signs and files: Form 941 quarterly, Form 940 annually, Illinois withholding and unemployment wage reports
  • Ask for sample filing confirmations from a recent client month - on-time filers produce them without hesitation
  • Confirm whether the provider is a reporting agent, a certified professional employer organization, or software only - the liability differs and the IRS publishes the distinction
  • Confirm the error policy in writing: who pays interest and penalties on a provider-caused late deposit, and up to what limit
  • Check that the provider registers you correctly in every state where you have an employee, including new states mid-year
  • Confirm data portability: full payroll history export in a usable format, at any time, at no charge
  • Verify the renewal price and the notice window required to cancel, then calendar the notice date the day you sign

What this means in Detroit

A late deposit costs 2% to 15% of the deposit; a full year of payroll processing for a small Detroit employer costs less than one such penalty on a modest payroll. Price the service second and the failure mode first.

Common questions

How much does a payroll service cost for a small business?

In 2026 published pricing, payroll services charge a monthly base fee of roughly $20-$150 dollars plus $4-$15 dollars per employee per month. A ten-employee business commonly lands between $70 and $250 dollars a month before add-ons. Full outsourced processing is often quoted per person instead, at roughly $30-$100 dollars per employee per month. These are directional market ranges, not quotes.

If my payroll provider files late, who pays the IRS penalty?

The employer is responsible to the IRS regardless. The IRS states that outsourcing payroll duties does not relieve an employer of the responsibility to deposit and report employment taxes - the notice follows your EIN. Many providers offer a contractual guarantee to cover penalties they cause, but that is a private contract, not a change in tax liability. Get the guarantee, its limits and its claim process in writing.

What is the penalty for depositing payroll taxes late?

The federal failure-to-deposit penalty runs 2% for deposits up to 5 days late, 5% for 5-15 days, 10% beyond 15 days, and 15% if the tax remains unpaid more than ten days after the IRS issues a notice. Filing Form 941 late adds a separate penalty of about 5% of the unpaid tax per month, capped near 25%.

What is state unemployment tax and why does my rate change?

Every employer pays state unemployment insurance tax on each employee's wages up to a state taxable wage base. New employers are assigned a starting rate; after enough history, the rate moves within a statutory band based on claims experience. Two identical payrolls can owe very different amounts because both the rate and the wage base are set state by state - the Illinois figures are published on this site's state page.

Is payroll priced per employee or per payroll run?

Both models exist. The common structure is a monthly base fee plus a per-employee fee, which is predictable regardless of how often you run payroll. A per-run model charges each time you process, which favors businesses paying monthly and penalizes weekly payrolls. Ask for the all-in annual total under your actual pay frequency - that single number makes the two models comparable.
