Essential Records for Small Businesses in Wisconsin

Maintaining organized and accurate records is crucial for small businesses operating in Wisconsin. Proper recordkeeping supports compliance, simplifies tax filing, and enhances operational efficiency.

Key Types of Records to Keep

  • Business Registration Documents: Keep copies of your Wisconsin business registration, articles of incorporation or organization, and any permits or licenses.
  • Financial Records: Maintain detailed records of income, expenses, invoices, receipts, bank statements, and credit card transactions. These are essential for bookkeeping and tax reporting.
  • Payroll Records: Track employee wages, tax withholdings, benefits, and hours worked. Wisconsin employers must comply with state payroll tax requirements and reporting.
  • Tax Documents: Retain copies of federal, state, and local tax filings, including sales tax returns if applicable. Wisconsin businesses must collect and remit state sales tax on taxable goods and services.
  • Employee Records: Maintain employment agreements, employee classification documents, I-9 forms, and records related to workplace safety and compliance.
  • Contracts and Agreements: Keep signed contracts with vendors, clients, and partners to manage obligations and disputes effectively.
  • Insurance Policies: Store copies of business insurance policies such as liability, workers’ compensation, and property insurance.
  • Compliance Documentation: Preserve records related to state and federal regulatory compliance, including licensing renewals and inspection reports.

Record Retention Guidelines
