In a company, payroll is the sum of all financial records of salaries for an employee, wages, bonuses and deductions. In accounting, payroll refers to the amount paid to employees for services they provided during a certain period of time. Payroll plays a major role in a company for several reasons.
From an accounting perspective, payroll is crucial because payroll and payroll taxes considerably affect the net income of most companies and they are subject to laws and regulations (e.g. in the US payroll is subject to federal and state regulations). From an ethics in business viewpoint payroll is a critical department as employees are responsive to payroll errors and irregularities: good employee morale requires payroll to be paid timely and accurately. The primary mission of the payroll department is to ensure that all employees are paid accurately and timely with the correct withholdings and deductions, and to ensure the withholdings and deductions are remitted in a timely manner. This includes salary payments, tax withholdings, and deductions from a paycheck.

In the United States, "payroll taxes" are separate from income taxes, although they are levied on employers in proportion to salary; the programs they fund include Social Security, and Medicare. U.S. income and payroll taxes collected through deductions are considered to be trust fund taxes, because the employer holds the deducted money in trust for later remittance.
Payroll taxes in U.S. 
Before considering the payroll taxes we need to talk about the basic formula for the Net Pay. From gross pay (the salary paid to the employee) one or more deductions are subtracted, to arrive at Net Pay. Thus the employee's gross pay (pay rate times number of hours worked, including any overtime) minus payroll tax deductions, minus voluntary payroll deductions, is equal to Net Pay. Payroll tax deductions play a critical role and because they are provided by law they are known as Statutory payroll tax deductions.
The employer must withhold payroll taxes from an employee's check and hand them over to several tax agencies by law. Payroll taxes include the following:
- Federal income tax withholding, based on withholding tables in "Publication 15, Employer's Tax Guide" by Internal Revenue Service - IRS;
- Social Security tax withholding. The employee pays 6.2 percent of the salary or wage, up to 110,100 (as of 2012). The employer also pays 6.2 percent in Social Security taxes. If you are self-employed, you pay the combined employee and employer amount of 12.4 percent in Social Security taxes on your net earnings;
- Medicare tax. The employee pays 1.45 percent in Medicare taxes on the entire salary or wage. The employer also pays 1.45 percent in Medicare taxes. If you are self-employed, you pay the combined employee and employer amount of 2.9 percent in Medicare taxes on your net earnings;
- State income tax withholding;
- various local tax withholding, such as city taxes, county taxes, school taxes, state disability, and unemployment insurance.

- Publication 15, (Circular E), Employer's Tax Guide. This publication explains employer's tax responsibilities. It explains the requirements for withholding, depositing, reporting, paying, and correcting employment taxes. It explains the forms any employer must give to its employees, those employees must give to the employer, and those employer must send to the IRS and SSA (Social Security Administration). This guide also has tax tables needed to figure the taxes to withhold from each employee;

- Publication 15-B. Employer's Tax Guide to Fringe Benefits. This publication supplements Publication 15 (Circular E), Employer’s Tax Guide, and Publication 15 - A, Employer’s Supplemental Tax Guide. This publication contains information about the employment tax treatment of various types of noncash compensation.
In the earlier part we have considered payroll taxes related to employee's side. Now it's the moment to talk about the Employer Payroll Taxes Employers are responsible for paying their portion of payroll taxes. These payroll taxes are an expense over and above the expense of an employee's gross pay. The employer-portion of payroll taxes include the following:
- Social Security taxes (6.2% up to the annual maximum);
- Medicare taxes (1.45% of wages);
- Federal unemployment taxes (FUTA);
- State unemployment taxes (SUTA).
Very often you can hear people using FICA in their terminology. FICA stands for the Federal Insurance Contributions Act and the FICA tax consists of both Social Security and Medicare taxes. As we explained earlier both parties pay half of these taxes. Employees pay half, and employers pay the other half. Social Security and Medicare taxes are paid both by the employees and the employers. In summary together both halves of the FICA taxes add up to 15.3 percent.
Any employer is responsible for paying the employer's share of payroll taxes, for depositing tax withheld from the employees' paychecks, preparing various reconciliation reports, accounting for the payroll expense through their financial reporting, and filing payroll tax returns. As you see this suite of employer payroll tax responsibilities is far above issuing paychecks to employees.
Companies typically generate their payrolls at regular intervals, for the benefit of regular income to their employees. The regularity of the intervals varies from company to company, and sometimes between job grades within a given company. Common payroll frequencies include: daily, weekly, bi-weekly/fortnightly (once every two weeks), semi-monthly (twice per month), and to a somewhat lesser extent, monthly. Less common payroll frequencies include: 4-weekly (13 times per year), bi-monthly (once every two months), quarterly (once every 13 weeks), semi-annually (twice per year), and annually.
Businesses may decide to outsource their payroll functions to an outsourcing service like a Payroll service bureau or a fully managed payroll service. These can normally reduce the costs involved in having payroll trained employees in-house as well as the costs of systems and software needed to process a payroll. Where this may reduce the cost for some companies many will foot a bigger bill to outsource their payroll if they have a special designed payroll program or payouts for their employees. In many countries, business payrolls are complicated in that taxes must be filed consistently and accurately to applicable regulatory agencies. Restaurant payrolls which typically include tip calculations, deductions, garnishments and other variables, can be difficult to manage especially for new or small business owners.
In the UK, payroll bureaus will deal with all HM Revenue & Customs inquiries and deal with employee's queries. Payroll bureaus also produce reports for the businesses' account department and payslips for the employees and can also make the payments to the employees if required.
Another reason many businesses outsource is because of the ever increasing complexity of payroll legislation. Annual changes in tax codes, Pay as you earn (PAYE) and National Insurance bands as well as statutory payments and deductions having to go through the payroll often mean there is a lot to keep abreast of in order to maintain compliance with the current legislation.
