Unemployment rate, taxable wage base, minimum wage and withholding
Federal payroll rules are identical everywhere; the money differs by state. What Illinois assigns a new Diamond employer, what wage base it applies, and what its minimum wage requires are below with state sources.
Two free marketplace paths: one form brings back multiple vetted payroll providers who know they are competing for the account.
Illinois assigns new employers a state unemployment tax rate of 3.35% on wages up to a taxable base of $14,250 per employee per year, which is the state-set portion of every Diamond payroll and moves with claims experience over time.
Illinois sets its minimum wage at $15.00, the floor every Diamond hourly rate has to clear before overtime, tip credits and local ordinances are applied on top.
Employers in Diamond's county pay about $60,715 a year per employee on average across 17,169 covered jobs (Census County Business Patterns 2023) - the wage base every unemployment rate and withholding schedule is applied to locally.
Federal payroll rules are identical in every state; the expensive differences are local. Illinois assigns a state unemployment tax rate and a taxable wage base, sets a minimum wage that may sit above the federal floor, and runs its own withholding registration and deposit schedule. Any Diamond payroll quote that does not account for those is a quote for a different business.
Two Diamond businesses with identical payrolls can owe materially different amounts because of Illinois's unemployment tax alone: new employers are assigned a starting rate, experience moves it within a statutory band, and the taxable wage base decides how much of each salary the rate applies to. Both figures are published by the state and shown below with sources.

What Illinois adds to every payroll
| Question | Illinois answer |
|---|---|
| State unemployment tax - new employer rate | 3.35% (range 0.75% - 7.05%) |
| Taxable wage base per employee | $14,250 - PARTIALLY primary-confirmed |
| State minimum wage | $15.00 - Tipped employees may be paid 60% of the minimum wage ($9.00) provided tips bring them to $15.00 |
| State income tax withholding | flat 4.95% |
Illinois recomputes a statewide 'State Experience Factor' every year (102% for 2026) that scales every employer's rate, and it charges staffing/waste-management employers (NAICS sector 56) a higher new-employer rate of 3.45% instead of the standard 3.35%.

Why two identical Diamond payrolls owe different amounts
Unemployment tax is charged as a rate against a capped amount of each employee's wages, and both halves of that formula are state decisions. A new Diamond employer is assigned a starting rate; once there is claims history the rate moves within the state's statutory band. The wage base decides how much of a salary the rate touches - which is why a state with a high base and a low rate can cost more than the reverse. Neither number is negotiable, but both are worth knowing before comparing payroll quotes that quietly assume one state.
What this means in Diamond
Cheap payroll and expensive payroll fail in the same direction: a filing that did not happen. What you are buying, at any price, is verifiable proof that deposits and returns went out on time in Illinois - if a provider cannot produce that proof on request, the discount is not a discount.

Common questions
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.
Is it worth switching payroll providers?
Switching costs are lower than most owners assume - the practical constraints are having complete year-to-date wage data, timing the move at a quarter boundary where possible, and confirming the new provider registers you in every state. The savings case is rarely the base fee; it is usually the elimination of per-state, per-form and off-cycle charges that accumulated with a legacy plan.
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.
What hidden fees do payroll companies charge?
The recurring surprises are year-end W-2 and 1099 filing at roughly 4-8 dollars per form, additional state tax filings at 6-20 dollars per state per month for remote employees, off-cycle or bonus runs at 5-50 dollars each, setup or implementation fees, charges for mailed paper checks, and per-employee fees that continue for terminated staff. Ask for the full fee schedule in writing, not the pricing page.
Do I have to file W-2s and 1099s electronically?
Almost certainly yes. The threshold dropped to 10 returns: if you file 10 or more information returns of all types combined in a calendar year, they must be filed electronically. Articles still citing the old 250-return threshold are out of date. Any full-service payroll provider files electronically as standard - confirm it is included rather than billed per form.
