Outsourcing pay comes in 2 depths. A payroll provider turns hours into paychecks and sends the tax money where it belongs, yet the business remains the sole employer. A Professional Employer Organization (PEO) co-employs your staff, so it can also run benefits, workers’ comp, and HR paperwork. Maryland counts 696,710 small businesses employing 1.2 million people. Many of those owners shop for payroll services, Maryland being a state with unusually layered paychecks.
Those rules start with 2 income taxes on every check, state and county. Paid leave contributions begin on January 1, 2027, and 2 counties pay above the state minimum. Benefits differ too: a Maryland PEO cannot move a small employer into its large group health plan.
Payroll and PEO Support for Maryland Employers
The state income tax runs from 2% up to 6.5% on income above $1 million. Each county or Baltimore City adds 2.25% to 3.30%, set by the employee’s home address on Form MW507, the state withholding certificate. Anyone who skips the form is withheld at 3.30%. FAMLI deductions arrive in 2027, and Montgomery and Howard counties set higher hourly minimums. Payroll solution services Maryland employers buy earn their fee by getting each rate right.
INSIGHT: What comes out of a Maryland paycheck?
Maryland withholds state and county income tax from the same paycheck. A FAMLI deduction joins them in 2027.
- State income tax: 2% up to 6.5%, with new 6.25% and 6.5% brackets for high earners (2026).
- County income tax: 2.25% in Worcester up to 3.30% in Dorchester and Kent (2026).
- FAMLI: 0.9% of wages from January 1, 2027, split evenly at 15 or more employees.
- Minimum wage: $15.00 an hour statewide (October 2026).
Then come the charges only the business pays. Maryland’s jobless insurance (UI) is charged on the first $8,500 of each employee’s wages, and workers pay none of it. Rates run from 1.0% to 2.6% for new firms in 2026 and from 0.30% to 7.50% for others. BEACON, the state’s online system, reports UI wages each quarter. Each new or rehired worker must reach the state directory within 20 days. Federal FICA and FUTA come on top, and Maryland payroll services file all of it on schedule.
Workers’ compensation is required for almost every employer with 1 or more employees, and a PEO can cover staff under its own program. Sick and safe leave must be tracked and paid for 15 employees. On health plans, the Maryland Insurance Administration (MIA) found that small employers cannot join a PEO’s large group plan. A 2026 bill to change that stalled. Bundled HR and payroll services Maryland PEOs sell add value through administration, plan choice, and HR help. A PEO 401(k) also meets the MarylandSaves rule.
INSIGHT: What does a Maryland employer have to provide?
Workers’ comp and sick and safe leave reach even small employers. Many firms without a retirement plan must also offer the state program.
- Workers’ compensation: required for employers with 1 or more employees, with few exceptions (WCC, 2018 guidance).
- Sick and safe leave accrues at 1 hour for every 30 worked, capped at 40 a year; paid from 15 staff (2026).
- MarylandSaves: expected of employers in business for 2 years with automated payroll and no qualified plan.
- Affordable Care Act (ACA) duties: begin once you hit 50 full-time equivalents (IRS, 2026).

Most owners weigh 3 models. Plain payroll covers checks and tax returns, nothing more. A PEO in Maryland becomes a co-employer and folds benefits, workers’ comp, and HR into the same contract, yet you still hire and steer the work. HR outsourcing without shared employment sits between them, and my note on what a PEO is explains the contract. The state licenses no PEOs, so check the IRS Certified PEO (CPEO) list and the voluntary ESAC directory. Then ask how a small Maryland group’s health plan is rated.
I reviewed 15 options for owners who already employ people here, from local payroll firms and PEOs to national providers. Each entry shows what it covers, how it prices, and who it suits, making it faster to choose a PEO for Maryland staff. Owners curious about nationwide providers can browse my list of the best PEO companies.
Top 15 PEO Maryland Providers and Payroll Companies
The PEO companies in Maryland and payroll firms below solve different problems, so start with 3 questions. Do you need pay and tax filing only, a full PEO, or HR help without co-employment? What is your headcount? Paid sick leave and the FAMLI employer share both switch on at 15, and the ACA mandate at 50.
The third question is distance. A firm in Rockville, Columbia, or Frederick may know your county better, while a national PEO brings a bigger HR team. No single best payroll service for Maryland businesses fits every size and industry.
I scored every payroll service provider in Maryland on the same points. They start with state and county withholding, FAMLI readiness, county wage floors, and leave records. Then come the workers’ comp model, how health plans are sourced, CPEO or ESAC status, and pricing clarity.
All 15 providers appear in A-to-Z order. The sequence says nothing about quality, preference, or ranking.

How Much Payroll Services and PEOs Cost in Maryland
Payroll services in Maryland are cheaper. Most charge per pay run or per employee per month, and Maryland Employer Services charges a flat fee per check. PEOs pick 1 of 2 billing methods. Some, like Nextep, charge a set amount per worker each month; others take a share of gross payroll. None of the 15 providers here publish a PEO rate, so every figure comes on quote. The PEO fee normally covers pay runs, benefits enrollment, injury-policy paperwork, and an HR adviser.
Other costs sit outside the fee. Insurance premiums, retirement plan fees, and setup charges come on separate invoices. When comparing PEO services in Maryland, add the statutory costs too. They include UI on the first $8,500 of wages, the FAMLI employer share (starting in 2027 for employers with 15 or more employees), and federal FICA and FUTA. Small group health premiums often decide the total, so compare cost per employee per year.
INSIGHT: What should HR and payroll services in Maryland handle for you?
Maryland payroll has a county layer and a new leave program. Have every candidate walk you through its process for each.
- County income tax: 2.25% to 3.30%, by employee residence (2026).
- Jobless insurance: $8,500 wage base; newer businesses pay 1.0% to 2.6% (2026).
- FAMLI: 0.9% of wages from January 1, 2027.
- Montgomery County minimum wage: up to $18.00 from July 1, 2026.
Some Maryland companies send seasonal crews or a sales rep south to Florida. With no state income tax or leave fund there, a Florida paycheck has fewer lines. Compare the PEO companies in Florida I reviewed before adding staff there.
A hire in Los Angeles or San Diego changes the math again, with disability insurance deductions and overtime counted by the day. Read my take on PEO companies in California before a first West Coast hire.
FAQs on Payroll Services and PEOs in Maryland
Should a Maryland small business use a payroll provider or a PEO?
With outsourced payroll, a vendor processes each check, withholds state, county, and federal taxes, and files every return. The business alone stays the employer. Under co-employment, the provider shares that role, which lets it add group benefits, injury coverage, and HR paperwork. Teams that only want checks done right tend to begin with payroll alone. Those who want HR advice and a 401(k) often move to a PEO after about 10 staff. Hiring and daily direction stay with you in both setups.
Can a PEO get my small Maryland business large group health rates?
Usually not. A January 2025 state insurance study named Maryland as 1 of only 3 states with this limit, alongside Maine and Wyoming. Small employers here cannot join a co-employment provider’s large group health plan. Small firms therefore still buy coverage under small group rules. A bill to change this passed the House in 2026 but did not pass the Senate. A PEO can still help with plan choice, enrollment, and administration, so compare the actual premiums each provider quotes.
When do Maryland FAMLI contributions start?
Contributions to the state’s paid family and medical leave program start on January 1, 2027. The total rate is 0.9% of wages, up to the Social Security wage base. Employers with 15 or more employees split the cost evenly with their staff. Employers with fewer than 15 do not pay the employer half but must still withhold and remit the employee half. Benefits are scheduled to begin on January 3, 2028. The rate may change each year, up to a 1.2% cap.
Do Maryland employers withhold county income tax?
Yes. Every county and Baltimore City levies a local income tax, from 2.25% in Worcester County to 3.30% in Dorchester and Kent counties for 2026. Employers withhold it together with state income tax from each paycheck, based on the county where the employee lives, as shown on the MW507 form. If an employee never files the form, employers withhold at the highest local rate. Anne Arundel and Frederick counties use graduated local rates, so check the county code on pay stubs after an employee moves.
How much does outsourced payroll or a PEO cost in Maryland?
Payroll vendors bill by run, by check, or by worker each month. PEOs charge either a per-employee-per-month fee or a percentage of total payroll, depending on headcount, industry, and benefits. Insurance premiums and retirement plan fees normally come on top. Unemployment insurance and the employer share of paid leave stay with you, so compare total yearly cost per employee rather than the headline fee. A sample invoice makes that comparison easier.
What is the minimum wage in Maryland for 2026?
The statewide minimum is $15.00 an hour for most adult workers. Employers may pay tipped staff a $3.63 cash wage if tips bring them to the full rate. Montgomery County sets higher rates by employer size from July 1, 2026. Large employers pay $18.00, mid-sized ones $16.50, and small ones $15.95, with a $4.00 tipped cash wage. Howard County sets $16.00. Overtime at 1.5 times pay is due after 40 hours in a workweek, with longer thresholds in a few industries.
