Payroll‑compliance audits are typically carried out by government‑backed tax and labour regulators, though internal or external auditors may also perform compliance‑focused payroll reviews. Below are the main types of bodies that audit employer payroll practices.
National tax and revenue authorities
In most countries, the primary payroll‑compliance auditors are national tax agencies that oversee income‑tax withholding, employer‑withheld contributions, and related filings. Examples include:
-
IRS (Internal Revenue Service) in the United States
-
HMRC (Her Majesty’s Revenue & Customs) in the United Kingdom
-
URSSAF in France
-
Deutsche Rentenversicherung and local tax offices in Germany
-
SARS (South African Revenue Service)
These bodies check that correct amounts of income tax, social‑security, and other payroll‑related deductions have been calculated, withheld, and remitted on time.
Labour and workplace‑standards regulators
Labour‑focused agencies often audit employers to ensure compliance with wage‑and‑hour laws, minimum‑wage rules, overtime pay, and classification of workers. Key examples are:
-
Department of Labor (DOL) in the United States, which audits compliance with the Fair Labor Standards Act (FLSA), including minimum wage, overtime, and record‑keeping.
-
Labour inspectorates in the European Union, Canada, and many African and Asian countries, which visit worksites and review payroll and time‑keeping records to verify legal pay rates and hours.
Social‑security and pension‑related authorities
Many societies require employers to contribute to public social‑security and pension funds; these agencies also audit payroll figures against employee registers. Examples are:
-
Social Security Administration (SSA)–linked schemes in the U.S.
-
National pension commissions or provident‑fund boards in countries such as South Africa, India, and Nigeria, which verify that employer and employee contributions match payroll data.
Industry‑specific and plan‑level auditors
For retirement and benefit plans, independent auditors may be mandated under labour or benefits‑law frameworks. For example:
-
Under the Employee Retirement Income Security Act (ERISA) in the U.S., defined‑benefit pension plans must undergo annual audits by independent certified public accountants, often initiated or overseen by the Department of Labor.
-
Some countries require benefit‑fund trustees or insurers to verify that employer payroll contributions are accurate and timely, using payroll audits as part of their compliance process.
Internal and third‑party auditors
In addition to government bodies, employers may face audits from:
-
Internal‑audit or finance teams that review payroll controls, segregation of duties, and error‑rates.
-
External accounting firms performing compliance audits, often in response to tax or labour‑authority requirements or as part of broader financial‑statement audits.
Overall, the main regulatory bodies that audit employer payroll compliance are tax authorities, labour departments / inspectorates, and social‑security or pension‑scheme administrators, supplemented by internal and external auditors focusing on process, control, and error‑checking.
