What payroll costs in Groton - and what a late deposit costs
Payroll in Groton, CT is sold on a monthly price and settled on a penalty schedule. Providers quote a $20-$150 dollar base plus $4-$15 per employee; the IRS charges 2% to 15% for deposits that land late, and Connecticut sets its own unemployment-tax rate, minimum wage and final-paycheck deadline on top. All three layers are on this page with sources.
Two free marketplace paths: one form brings back multiple vetted payroll providers who know they are competing for the account.
Payroll services quoted to Groton businesses in 2026 run $20-$150 a month in base fees plus $4-$15 per employee per month, which puts a ten-person Groton 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 Groton business is comparing.
Connecticut assigns new employers a state unemployment tax rate of 1.9% on wages up to a taxable base of $27,000 per employee per year, which is the state-set portion of every Groton 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 Groton 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, Connecticut adds its own unemployment filings, and every deadline carries a percentage penalty. A Groton 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 Connecticut adds to every payroll
| Question | Connecticut answer |
|---|---|
| State unemployment tax - new employer rate | 1.9% (range 1.1% - 9.9% (includes the 1.0% Fund Solvency Tax added to each employer's charged rate)) |
| Taxable wage base per employee | $27,000 - Confirmed on CTDOL's own 'Information on Unemployment Tax Rate for Calendar Year 2026' page: taxable wage base rises from $26,100 to $27,000 |
| State minimum wage | $16.94 - A 2026 adjustment DID occur: effective January 1, 2026 the rate rose from $16.35 to $16.94/hr, a 3.6% increase |
| State income tax withholding | graduated 2%–6.99% |
Connecticut adds a flat 1.0% Fund Solvency Tax to every employer's charged rate, so no employer - however clean its claims history - can pay less than 1.1% in 2026.

What a Groton 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
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 Connecticut - if a provider cannot produce that proof on request, the discount is not a discount.
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.
| Path | What it is | Why it made the bar |
|---|---|---|
| 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 Groton decision path
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.

Common questions
How much does payroll cost per employee per month?
Per-employee fees cluster at $4-$15 dollars per month on top of the base fee for standard payroll software and services. Fully outsourced processing and PEO-style arrangements are quoted differently - commonly $30-$100 dollars per person per month or a percentage of gross payroll - and bundle benefits administration and compliance work that standard payroll does not include.
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 Connecticut 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.
What do I need to give a payroll company to get a quote?
Employee count split into salaried, hourly and contractors; every state where someone physically works; pay frequency; expected off-cycle runs; and whether you need benefits, time tracking, garnishments or workers' comp integration. Providing all of it up front is what makes competing quotes genuinely comparable - and it is exactly what a marketplace form collects once and sends to several providers.
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.
How fast do I have to report a new hire?
The federal baseline is 20 days from the date of hire, reported to your state's new-hire directory, and a number of states set shorter deadlines. Rehires generally count, and some states also require reporting independent contractors. Confirm which filing your payroll provider makes for you - new-hire reporting is commonly included, but not universally.
