Many Maryland employers are discovering they may pay more taxes in Maryland in 2026 — even without hiring additional staff or increasing wages significantly.
For small to mid-sized businesses, the increase often isn’t caused by one dramatic change. It’s the accumulation of:
- Local income tax adjustments
- Unemployment insurance rate recalibrations
- Multi-state payroll complications
- Benefit-related tax reporting shifts
- Payroll system configuration errors
What makes this more challenging is that the exposure often goes unnoticed until year-end reconciliation or audit.
Here’s what this means for your business — and how to prepare.

What’s Driving Higher Tax Exposure in Maryland in 2026?
Businesses that pay more taxes in Maryland this year are typically experiencing one or more of the following operational shifts.
1. Local Income Tax Variability
Maryland’s county-level income tax structure adds complexity. Rates vary by jurisdiction, and employees living in one county but working in another can create withholding discrepancies.
Common employer mistakes include:
- Incorrect jurisdiction mapping in payroll systems
- Failing to update local tax tables at the start of the year
- Misclassifying remote employee residency
When payroll systems are not aligned with current Maryland local income tax rates, under- or over-withholding can occur — leading to employer correction costs.
2. Unemployment Insurance (SUI) Rate Changes
Maryland employers may see unemployment insurance rate adjustments based on:
- Claims history
- Workforce turnover
- Industry classification
- State trust fund balance recalculations
SUI rate notices are typically issued annually. However, breakdowns occur when:
- Payroll providers fail to update new rate codes
- Rate notices are not routed to the right internal contact
- Multiple FEINs are incorrectly grouped
A misapplied rate can materially increase your payroll tax burden — or trigger retroactive assessments.
3. Multi-State Workforce Complications
Maryland-based businesses increasingly employ remote or hybrid workers in surrounding states such as Virginia, Pennsylvania, or Delaware.
When this happens:
- Tax nexus can be triggered
- Reciprocal agreements must be applied correctly
- Resident vs. nonresident withholding rules shift
Employers who assume Maryland withholding applies universally may unintentionally pay more taxes in Maryland while also creating compliance exposure in other states.
Where Businesses Commonly Miscalculate
The issue is rarely that Maryland suddenly raises one dramatic tax. It’s typically a systems failure.
Employers often:
- Fail to audit payroll tax setup annually
- Overlook local jurisdiction coding errors
- Miss state-issued rate change notices
- Rely on manual overrides for special tax situations
- Do not reconcile quarterly filings against payroll registers
In 2026, small misalignments compound quickly.
The Business Impact of Paying More Taxes in Maryland
If your organization begins to pay more taxes in Maryland, the impact goes beyond higher checks written to the state.
Compliance Risk
- Under-withholding can trigger employee dissatisfaction and correction demands
- Over-withholding can require amended filings
- Incorrect SUI reporting may prompt audits
- Multi-state errors increase exposure across jurisdictions
Financial Risk
- Penalties and interest on underpaid taxes
- Retroactive SUI rate adjustments
- Duplicate taxation in non-reciprocal states
- Administrative rework costs
Administrative Burden
- Manual reconciliations
- Amended quarterly reports
- Employee W-2 corrections
- Increased accounting intervention
Workforce Implications
- Employee confusion over net pay changes
- Increased payroll inquiries
- Perceived instability in payroll operations
For growing Maryland-based businesses, tax configuration errors erode operational trust quickly.
The System-Level Impact: This Is Not Just a Tax Issue
When businesses pay more taxes in Maryland, it often reveals a broader systems misalignment.
Payroll Configuration
- Local tax codes must align with employee home address data
- SUI rates must be assigned to the correct entity and state account number
- Reciprocity exemptions must be documented and stored
A single incorrect tax profile mapping can cascade across hundreds of paychecks.
HR Documentation
- Employee residency forms must be maintained
- Remote work agreements should specify primary work location
- SUI rate notices must be retained for audit trail
Benefits Administration
Certain pre-tax deductions impact taxable wage calculations. If benefits are not integrated correctly:
- State taxable wages may be overstated
- Local tax calculations may misfire
- W-2 Box 16 reporting can become inconsistent
Multi-State Coordination
For Maryland-based employers with out-of-state workers:
- State withholding certificates must be collected
- Reciprocal agreements must be coded correctly
- Tax nexus determinations should be reviewed annually
Reporting and Audit Exposure
Quarterly filings (Form MW506, unemployment filings) must reconcile exactly to payroll registers. Variances signal compliance breakdowns.
This is why tax increases often reflect operational misalignment rather than legislative shock.
Action Plan: What Smart Maryland Businesses Do in 2026
If you suspect you may pay more taxes in Maryland, take a structured approach.
Step 1: Audit Payroll Tax Setup
- Confirm current Maryland local tax rates by employee county
- Verify SUI rate accuracy against state notice
- Review reciprocity coding for nonresident employees
Run a payroll register sample and validate tax calculations manually.
Step 2: Review Multi-State Exposure
- Identify remote employees
- Confirm resident vs. work-state withholding
- Evaluate nexus triggers
Do not assume Maryland-only compliance.
Step 3: Align Systems
- Ensure HR address records sync with payroll tax engines
- Confirm benefits deductions feed properly into state taxable wages
- Validate entity-level tax ID configuration
This is where integration failures often occur.
Step 4: Update Documentation
- Maintain SUI rate letters
- Store reciprocity exemption forms
- Document tax configuration changes
Audit readiness requires documentation discipline.
Step 5: Assign Oversight
Designate internal ownership:
- Who monitors rate notices?
- Who reconciles quarterly filings?
- Who audits payroll configuration annually?
Tax compliance without ownership becomes reactive.
Maryland-Specific Considerations for 2026
Maryland businesses face unique structural complexity:
- County-level income tax layering
- High concentration of multi-state commuters
- Remote workforce spillover into D.C. and Virginia
- Regulated industries with fluctuating workforce levels
For professional services firms, nonprofits, healthcare providers, and contractors operating across county lines, payroll precision is non-negotiable.
Businesses that scale without tax infrastructure review are most likely to pay more taxes in Maryland unintentionally.
Strategic Perspective: Complexity Is Compounding
Maryland’s tax environment is not necessarily becoming unstable. It is becoming more interconnected.
Payroll, HR documentation, benefits administration, and multi-state workforce strategy now intersect at every pay cycle.
Organizations that treat payroll tax as a background administrative function often discover exposure only after an audit or year-end reconciliation.
Organizations that treat it as an operational system manage risk proactively.
That distinction matters in 2026.
