The honest threshold, in deadlines rather than headcount
Software plus discipline genuinely beats a service for some Zachary businesses and quietly loses for others. The dividing line is not headcount - it is how many deadlines your payroll generates. Both sides are costed below.
Two free marketplace paths: one form brings back multiple vetted payroll providers who know they are competing for the account.
Running payroll in-house in Zachary is cheaper on paper - payroll software costs a fraction of full service, and a dedicated payroll specialist averages about $64,865 a year in 2026 wage data - right up until one deposit lands late and the 2%-15% federal penalty applies.
The county around Zachary holds 12,542 business establishments, of which 10,380 employ fewer than 20 people - the size band where payroll is bought as a service rather than staffed, per Census County Business Patterns 2023.
Employers in Zachary's county pay about $60,945 a year per employee on average across 244,574 covered jobs (Census County Business Patterns 2023) - the wage base every unemployment rate and withholding schedule is applied to locally.
Most Zachary owners who move to a full-service provider are not buying time back - they are buying a named party who files on schedule. That is worth paying for, with one permanent caveat this guide will keep repeating: the IRS still holds the employer responsible, so the provider you pick has to be one whose filings you can verify.
Doing payroll in-house is genuinely cheaper right up to the moment it is not. Payroll software costs a fraction of a full-service provider; a payroll specialist costs about $64,865 dollars a year in 2026 wage data; and the arithmetic changes completely on the first late deposit, which carries a 2% to 15% federal penalty on the deposit itself.
Put a payroll options comparison out to competing quotes before you compare prices

The three ways to run payroll, costed
| Option | 2026 cost | What it assumes about you |
|---|---|---|
| Do it manually | Your hours plus filing time | One state, salaried staff, no turnover, and a calendar you never miss |
| Payroll software | $20-$150/mo plus $4-$15/employee | You still own the deadlines; the software does the arithmetic |
| Full-service payroll | $70-$250/mo at 10 employees | A named party files on schedule - you verify that it happened |
| In-house payroll specialist | $64,865/year | Enough volume and complexity to justify a salary line |
The complexity test for a Zachary business
- Employees in more than one state - each adds a registration and a filing schedule
- Hourly staff with overtime, or tipped wages with a tip credit
- Wage garnishments, child-support orders or benefit deductions
- Contractors alongside employees, with 1099s at year end
- Turnover - every departure triggers a state final-paycheck deadline
- Bonus or commission runs outside the normal cycle
Two or more of those and the error probability climbs faster than the fee difference between doing it yourself and hiring it out. One or none, and software is a defensible choice for a Zachary employer - provided the deposit calendar is somebody's explicit job.
What this means in Zachary
A late deposit costs 2% to 15% of the deposit; a full year of payroll processing for a small Zachary employer costs less than one such penalty on a modest payroll. Price the service second and the failure mode first.

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.
When does a final paycheck have to be paid?
That is set by state law, and it differs for employees who are fired versus employees who quit. Several states require immediate payment on termination; others allow the next regular payday; a few add a penalty that accrues per day until the check is delivered. Unused vacation payout is likewise state-specific. The rule for Louisiana is on this site's final-paycheck page with its source.
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.
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%.
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.
