NATIONAL RESOURCES. MARYLAND SUPPORT.
TriNet brings Maryland businesses the resources of a national HR provider:
An all-in-one HR platform, access to large group benefit plans, and dedicated HR professionals who support companies in every US state. From Baltimore to Columbia to Annapolis, Maryland companies use TriNet to simplify HR and get time back for the work that matters.
What does that look like day to day?
Payroll processing, benefit plan administration, risk mitigation, and real answers to the HR questions that come up as your team grows. And because TriNet's solutions are tailored by industry, the support you get fits the business you actually run.
Operating in Maryland also means keeping up with state-specific employment-related requirements, and that's where TriNet's HR expertise comes in.
Our team helps Maryland employers navigate areas like:
| Paid sick and safe leave: | Maryland has state-level paid sick and safe leave requirements under the Maryland Healthy Working Families Act, and local jurisdictions may have additional requirements. TriNet helps support the implementation and administration of leave policies that implement applicable state and local rules. |
| Family Medical Leave: | Starting in 2027, employers in Maryland must register and contribute and/or take employee deductions for paid family/medical leave to that can be taken starting January 2028. |
| Pay transparency: | Maryland's Equal Pay for Equal Work Act shapes how employers post roles and discuss compensation. TriNet's HR professionals help you navigate what that means for your hiring. |
| Salary History Inquiry Restrictions: | Maryland employers are restricted from relying on, seeking, or considering an applicant’s wage history when making compensation decisions. |
| Minimum wage: | Maryland sets its own minimum wage requirements, and some counties set additional local rates. TriNet's payroll platform helps you keep pay rates current across every location you operate in. |
| Final pay: | The Maryland Wage Payment and Collection Law sets timing requirements for a departing employee's final paycheck. TriNet helps support your team through the offboarding and final pay processes with confidence. |
| Fair hiring: | Maryland's Criminal Record Screening Practices Act limits when employers can ask about criminal history during hiring. TriNet helps you structure applications and interviews accordingly. |
| Meal and rest breaks: | Maryland sets meal and rest break requirements for certain retail employees. TriNet helps you build scheduling and timekeeping processes that account for them. |

How TriNet Supports Maryland Businesses
Every Maryland business comes to HR outsourcing differently. Some want one comprehensive solution. Others want expert administrative support while staying the sole employer of record. TriNet offers both.
For many Maryland businesses, TriNet HR Plus is the natural starting point.
TriNet HR Plus
An administrative services organization, or ASO delivers HR administration, payroll, and compliance support without the co-employment structure. It's often the right fit for businesses that want expert HR help while remaining the sole employer of record.
TriNet PEO
A full-service HR co-employment solution that provides access to benefits, payroll processing and risk mitigation. Powered by expert support and leading technology, TriNet PEO helps businesses reduce HR administrative burdens so they can focus on running and growing their business.
What you get with either solution:

Frequently Asked Questions
TriNet offers two ways to outsource HR, and the right fit usually comes down to size, industry, and how much of a bundled solution you need.
- TriNet PEO is a co-employment solution for businesses with five to 500 employees. TriNet takes on much of the payroll taxes, workers’ compensation, and PEO-sponsored benefits administration, provides access to large group benefit plans, and includes a $1 million employment practices liability insurance policy.
- TriNet HR Plus is an administrative services model (ASO) for businesses from one employee to 500*. You remain the sole employer of record, and TriNet delivers HR administration, payroll, and compliance support.
For many Maryland businesses, HR Plus is the natural starting point, and TriNet can support a move to PEO if co-employment becomes the better fit later.
- The solution you choose (TriNet PEO or TriNet HR Plus)
- The services and level of support you add
- The size of your team
This reference only the admin fee. HR Plus may include additional add-on services that you subscribe to, and PEO pricing may include itemized charges such as benefits and workers' compensation. And both may have implementation or setup fees**.
See TriNet PEO pricing and TriNet HR Plus pricing for how each model works, or talk with an expert for a quote based on your team.
Yes. Maryland requires paid sick and safe leave for many employers under the Maryland Healthy Working Families Act, with rules covering how leave accrues, how much can be used in a year, carryover, and which family members leave can cover. Some local jurisdictions, including Montgomery County, layer their own requirements on top. TriNet helps you:
- Set up a leave plan that accounts for both state and local rules
- Administer accrual and tracking through one platform
- Navigate changing requirements
Yes. Maryland has its own payroll tax registrations, unemployment insurance wage base, and filing requirements, and they don't always mirror other states. TriNet's payroll services help you:
- Administer Maryland payroll tax obligations as you hire
- Keep up with wage base changes year to year
- Run multi-state payroll if your team works beyond Maryland
Yes. TriNet is a national provider supporting businesses in every US state, which matters in two situations:
- Remote and multi-state teams: if you hire outside Maryland, payroll, benefits administration, and HR support stay on one platform, with best practice guidance for each state's requirements.
- Expansion and relocation: if you're opening a location in another state or moving operations, the same team and platform go with you.
Plenty of Maryland businesses hire across state lines from day one, and TriNet is built for exactly that.
Yes. Maryland's Time to Care Act created a state paid family and medical leave insurance program (FAMLI) that is being phased in for employers, with requirements arriving on a schedule set by the state. However, employers must start to take employee deductions (and in some cases, also contribute to the state’s sick leave fund themselves) in 2027. It's the kind of change that's much easier to absorb with a plan in place. TriNet helps Maryland employers prepare for new state programs like this one and fold them into payroll and leave administration as they take effect.
* TriNet pricing may vary by region, industry, company size, and scope of services. Minimum fees and employee count may apply.
** HR Plus pricing is subject to a 10-employee minimum billing requirement.
