Key Benefits
Expert Tips & Insights
Practical advice from our payroll services team.
Classify Workers Correctly
Misclassifying employees as contractors is a costly mistake. The IRS has strict guidelines - when in doubt, treat them as employees.
Keep Payroll Records 7 Years
IRS and state agencies can audit up to 7 years back. Maintain complete records including timesheets, pay stubs, and tax filings.
Update W-4s Annually
Encourage employees to review their W-4 withholding each year, especially after major life changes like marriage or having a child.
Don't Touch Trust Fund Taxes
Payroll taxes withheld are held in trust for the government. Using them for business expenses leads to severe penalties and personal liability.
Automate Time Tracking
Manual time entry leads to errors and disputes. Implement digital time tracking that integrates directly with payroll.
Plan for Payroll Taxes
Set aside 15-20% of gross payroll for employer taxes. Unexpected tax bills are a leading cause of small business cash flow crises.
