Payroll Tax Changes for 2025  

In 2025, several changes to payroll taxes and related deductions are being implemented across various states and at the federal level. Here’s an overview of the most significant updates: 

Federal Payroll Taxes 

Social Security Taxable Wage Base: The taxable wage base for Social Security is increasing to $176,100 in 2025. This means that earnings above this threshold will not be subject to Social Security tax. 

Federal Income Tax Brackets: The IRS has adjusted federal income tax brackets for inflation, which may affect take-home pay. The tax rates remain the same (10%, 12%, 22%, 24%, 32%, 35%, and 37%), but the income thresholds have been increased. For single filer’s, the top rate of 37% applies to incomes over $626,350, while for married couples filing jointly, it applies to incomes over $751,600. 

State-Specific Payroll Taxes 

California: Starting in 2025, California workers will see an increase in payroll tax withholdings due to Senate Bill 951. For individuals earning around $100,000, there will be an estimated additional withholding of $100 from their paychecks, with variations based on total taxable income.

New York: Contributions to the New York Paid Family Leave program will increase to 0.388% of an employee’s gross wages, capping at a maximum annual contribution of approximately $354.53. 

Maryland: Beginning July 1, 2025, payroll deductions for Maryland’s Family and Medical Insurance will commence, leading into its launch in July 2026.
