Unemployment rate, taxable wage base, minimum wage and withholding
Federal payroll rules are identical everywhere; the money differs by state. What Washington assigns a new Hamilton 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.
Washington sets the new-employer unemployment tax rate by state formula rather than as one flat number, and applies it to the first $78,200 of each employee's wages per year - the state-set portion of every Hamilton payroll, shown in full in the table below.
Washington sets its minimum wage at $17.13, the floor every Hamilton hourly rate has to clear before overtime, tip credits and local ordinances are applied on top.
Employers in Hamilton's county pay about $60,690 a year per employee on average across 44,636 covered jobs (Census County Business Patterns 2023) - the wage base every unemployment rate and withholding schedule is applied to locally.
The state layer is where payroll compliance stops being generic. Washington sets the unemployment rate and wage base your account is billed on, the minimum wage your rates must clear, the deadline for reporting every new hire, and the rule that decides when a departing Hamilton employee's final check is legally late.
Federal payroll rules are identical in every state; the expensive differences are local. Washington 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 Hamilton payroll quote that does not account for those is a quote for a different business.

What Washington adds to every payroll
| Question | Washington answer |
|---|---|
| State unemployment tax - new employer rate | 115% of the average rate for all businesses in the employer's industry, with a floor of 1.00% (range 0.27% - 6.02% total for qualified employers) |
| Taxable wage base per employee | $78,200 - STALE-FIGURE WARNING: industry tables widely republish $72,800 for Washington - that is the 2025 value and is outdated; the state ESD figure for 2026 is $78,200 |
| State minimum wage | $17.13 - $17.13/hr for 2026 (L&I) |
| State income tax withholding | none — no state individual income tax on wages (a 7% tax applies to certain long-term capital gains, not wages) |
| Local payroll or income taxes | No local income tax, but Seattle levies a JumpStart payroll expense tax on large employers based on compensation paid to high earners — rates/thresholds not verified in this pass |
Washington has the highest UI taxable wage base in the country at $78,200 for 2026 - over eleven times the federal $7,000 floor - and adds a separate delinquency rate schedule that penalizes late filers with a permanently higher rate.

Why two identical Hamilton 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 Hamilton 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 Hamilton
The most expensive payroll service is the one whose mistake you sign for. The IRS states plainly that outsourcing payroll does not transfer the employer's responsibility to deposit and report employment taxes - which means a Hamilton business comparing a $20 dollar plan against a $150 dollar plan is comparing the wrong two numbers if either provider misses a deposit.

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.
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.
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 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 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.
