Understanding annual limits is crucial for accurate payroll management. Federal, state, and local tax agencies set specific annual limits for payroll deductions and taxes.
Taxes
Most taxes come with limits that affect your net pay.
Upon reaching these limits within a calendar year, you may see an increase in your take-home pay, or you might reach a threshold requiring additional taxes.
The employer and the employee are responsible for paying FICA, which is a combination of Social Security and Medicare taxes.
Employers and employees each pay 6.2%. The wage base for 2024 is $168,600. In 2025, the wage base will be updated to $173,200.
Both the employer and employee pay Medicare taxes of 1.45% each on all wages paid.
Employers and employees pay 1.45% each on all wages. There is an additional 0.9% tax on earnings over $200,000 for employees.

High wage earners and federal tax limits
When hiring an employee who has either reached or is nearing the wage base limits for FICA taxes, it's important to treat them like any other new hire.
The Social Security limit is determined based on an employee's work with a single employer.
This implies that even if an employee has already reached the annual Social Security limit with a previous employer, both you and the employee must continue withholding Social Security taxes on all wages paid under your employment until they reach the annual limit.
Deduction limits
Deductions play a crucial role in calculating an employee’s check.
Various deductions, when appropriately configured, can offer benefits to an employee's take-home pay.
Pre-tax deductions are typically Section 125 plans for health insurance and deferred compensation for retirement contributions.
Ages over 50 have a $7500 catch-up, and ages 60 - 63 have a $11,250 catch-up limit starting in 2025.

Unemployment wage base limit
The unemployment wage base limit represents the taxable wages that employers must compute and contribute towards unemployment taxes. The FUTA wage base limit stands at $7,000. Employers are liable to pay FUTA taxes on the first $7,000 of wages paid to each employee. This wage base limit resets annually on January 1.
The state unemployment (SUI) wage base limit varies from state to state, and in some cases, states may adjust the wage base limit on an annual basis.
