What payroll costs in Fontana - and what a late deposit costs
A Fontana business with ten employees typically pays $70-$250 a month for payroll processing in 2026. That figure tells you almost nothing about your risk: this guide prices the service, then prices the mistakes - federal deposit penalties, Kansas's unemployment tax, its minimum wage, and its final-paycheck rule - with the official sources next to each.
Two free marketplace paths: one form brings back multiple vetted payroll providers who know they are competing for the account.
Payroll services quoted to Fontana businesses in 2026 run $20-$150 a month in base fees plus $4-$15 per employee per month, which puts a ten-person Fontana payroll at roughly $70-$250 a month before year-end filing and add-on charges.
The federal penalty for depositing employment taxes late runs 2% up to 5 days late, 5% through 15 days and 10% beyond that, rising to 15% after an IRS notice goes unanswered - percentages applied to the deposit, not to the monthly fee a Fontana business is comparing.
Kansas assigns new employers a state unemployment tax rate of 1.75% (base rate on wages up to a taxable base of $15,100 per employee per year, which is the state-set portion of every Fontana payroll and moves with claims experience over time.
Payroll pricing is quoted per month and consumed per employee, which is why the same provider can look cheap to a three-person shop in Fontana and expensive to a thirty-person one. Multiply the base fee by twelve, add the per-employee fee times your headcount times twelve, add the year-end filing charge, and only then compare providers.
The reason payroll gets outsourced is rarely the arithmetic - it is the calendar. Federal deposits run on a schedule set by your prior-year tax liability, Form 941 is due the month after each quarter closes, Kansas adds its own unemployment filings, and every deadline carries a percentage penalty. A Fontana owner doing this alone is not saving money if a single deposit slips.

What payroll services cost in 2026
| What you are buying | 2026 published range | The number that actually matters |
|---|---|---|
| Monthly base fee | $20-$150/month | Meaningless alone - always price it with your headcount attached |
| Per employee, per month | $4-$15/employee/month | At 10 employees this is most of the bill: $70-$250/month all in |
| Fully outsourced processing | $30-$100/person/month | Quoted per person rather than base plus fee - bundles compliance work |
| Year-end W-2 and 1099 filing | $4-$8/form | Included at some tiers, billed at others - ask before January |
| Additional state filings (remote staff) | $6-$20/state/month | One remote hire in a new state can change the plan you need |
| Off-cycle or bonus runs | $5-$50 each | Bonus season is when this line shows up on the invoice |
| Setup / implementation | $0-$200 | Commonly waived at small-business tiers - ask, it is negotiable |
| A late federal deposit | 2%-15% of the deposit | The reason the monthly fee is the second-most important number (IRS IRC 6656) |

What Kansas adds to every payroll
| Question | Kansas answer |
|---|---|
| State unemployment tax - new employer rate | 1.75% (range 0.00% - 6.95%) |
| Taxable wage base per employee | $15,100 - STALE-FIGURE WARNING: payroll-vendor tables commonly still publish a $14,000 Kansas wage base - that value is outdated; the US DOL figure effective January 2026 is $15,100 |
| State minimum wage | $7.25 - K.S.A |
| State income tax withholding | graduated, roughly 5.2%–5.58% |
Kansas can assign a 0.00% rate to entire rate groups when a credit or solvency schedule is in force, meaning a qualifying Kansas employer can owe no state unemployment tax at all for the year.

What a Fontana quote should contain
- Employee count, split into salaried, hourly and contractors - contractors are usually priced separately or per 1099
- Every state where an employee physically works, including remote staff - each one commonly adds 6-20 dollars a month
- Pay frequency, and how many off-cycle or bonus runs you expect in a year at 5-50 dollars each
- Whether full-service tax filing and deposits are included at the quoted tier or sold as an add-on
- Year-end W-2 and 1099 filing: included, or 4-8 dollars per form
- Implementation or setup fee, and whether prior-year payroll history is migrated at no charge
- Benefits, garnishments, time tracking and workers' comp integration - each is commonly its own line
- The renewal price, in writing, alongside the first-year price
Why only these two paths
Withheld income tax and the employee share of FICA are trust funds - money that was never the company's. That is why the Trust Fund Recovery Penalty can reach an owner or officer personally, and why 'the company can't pay' is not an exit from this particular bill.
Hard bar, verifiable by anyone: free to the buyer, and structurally multi-vendor - one request produces several competing quotes, which is the check against over-quoting that no single sales relationship provides. Marketplaces that charge buyers or route to a single seller are not listed, and any listed path that drops below the bar gets removed. We list no individual payroll brand as a recommendation: this site does not rank providers it cannot audit filings for.

|---|---|---|
| BuyerZone | B2B quote marketplace covering payroll services and other business categories | One form, multiple vetted providers respond with competing quotes - free to buyers |
| 360Connect | B2B quote marketplace with local service-area matching for payroll solutions | Matches up to five suppliers per request, 100% free to buyers |
The Fontana decision path
A late deposit costs 2% to 15% of the deposit; a full year of payroll processing for a small Fontana employer costs less than one such penalty on a modest payroll. Price the service second and the failure mode first.

Common questions
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 Kansas figures are published on this site's state page.
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.
Can I do payroll myself instead?
Yes, and for a single-state business with a handful of salaried employees, software plus discipline is genuinely cheaper. The variables that change the answer are multi-state employees, hourly overtime, tipped wages, garnishments and turnover - each multiplies the number of deadlines. For scale, an in-house payroll specialist averages about $64,865 dollars a year in 2026 wage data, so the real comparison for most small employers is software plus your own hours versus a service.
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 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.
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.
