How Does 1st and 15th Payroll Work?

Payroll systems are fundamental to how businesses compensate their workforce, encompassing the process of calculating wages, withholding taxes, and distributing payments. Among the various payment frequencies, bi-monthly payroll, often referred to as semi-monthly payroll, is a common approach where employees receive their earnings on specific, fixed dates twice a month. This schedule impacts financial planning for employees and administrative responsibilities for employers.

Defining Bi-Monthly Payroll

Bi-monthly payroll refers to a payment schedule where employees are paid twice within each calendar month. This typically occurs on set dates, such as the 1st and the 15th, or the 15th and the last day of the month. This frequency results in exactly 24 paychecks distributed over a year. It offers predictability since the pay dates are generally consistent, regardless of the number of days in a month.

It is important to distinguish bi-monthly from bi-weekly payroll, a common point of confusion. While “bi-monthly” means twice a month, “bi-weekly” means every two weeks. A bi-weekly schedule leads to 26 paychecks annually, as there are 52 weeks in a year, meaning some months will have three paychecks. In contrast, bi-monthly payroll consistently provides two paychecks per month, which can simplify budgeting for fixed monthly expenses.

Understanding Pay Periods and Pay Dates

In a 1st and 15th payroll system, the pay periods are typically structured around these fixed dates. Work performed from the 1st of the month through the 15th is generally paid on the 15th, or sometimes at the end of the month. Conversely, work completed from the 16th through the last day of the month is usually compensated on the 1st of the following month. This setup ensures that work is reconciled and paid out in two distinct segments each month.

The actual pay date can shift if the 1st or 15th falls on a weekend or a public holiday. In such cases, it is standard practice for payment to be issued on the preceding business day. For example, if the 15th is a Saturday, employees would typically receive their pay on Friday the 14th. This adjustment helps ensure employees have access to their funds without delay due to bank closures. Employers often submit payroll several days before the official pay date, as processing requires time.

Payroll Calculations and Deductions

For employees on an annual salary, their total yearly earnings are divided by 24 to determine the gross pay for each bi-monthly paycheck. For instance, an employee with a $60,000 annual salary would receive $2,500 in gross pay per bi-monthly period ($60,000 / 24). For hourly employees, gross pay is calculated by multiplying their hourly rate by the number of hours worked within each specific pay period. This requires accurate tracking of hours from the 1st to the 15th and from the 16th to the month’s end.

Various deductions are then applied to this gross pay. Mandatory deductions include federal income tax, state income tax (if applicable), and Federal Insurance Contributions Act (FICA) taxes, which cover Social Security and Medicare. The Social Security tax is 6.2% on wages up to an annual limit, while Medicare tax is 1.45% on all wages, with an additional 0.9% Medicare tax on earnings exceeding $200,000 for individuals. Other common deductions can be voluntary, such as health insurance premiums, 401(k) contributions, and other benefits elected by the employee. These deductions reduce the gross pay to arrive at the net pay, the amount an employee actually receives.

When an employee starts or leaves employment in the middle of a pay period, their pay is prorated. This means their initial or final paycheck will be adjusted to reflect only the actual days or hours worked within that partial pay period. For a salaried employee, this often involves calculating a daily rate and multiplying it by the number of days worked. Hourly workers are simply paid for the exact hours recorded.

Implications for Employees and Employers

The 1st and 15th payroll schedule provides employees with a predictable income stream twice a month, which can align well with managing fixed monthly expenses like rent or mortgage payments. Receiving paychecks on consistent dates can simplify personal financial planning and budgeting. However, it requires employees to manage their funds for a full two weeks between paychecks, which can sometimes be a longer interval than bi-weekly pay.

For employers, this payroll frequency streamlines administrative tasks compared to weekly or bi-weekly schedules, as payroll is processed only 24 times a year instead of 26 or 52. This can reduce the administrative burden and associated processing costs. However, employers must maintain precise cut-off dates for tracking hours worked, especially for hourly employees, to ensure accuracy for each pay period ending on the 15th and the last day of the month. Ensuring timely disbursement when pay dates fall on weekends or holidays also requires proactive planning to avoid payment delays.
