Business finances

Insurance, banking, and bookkeeping

Keep business risks, money, and records separate from your personal finances.

Insurance to consider

  • General liability: covers third-party injury and property damage.
  • Professional liability: matters for consultants, designers, IT workers, and bookkeepers.
  • Business owner’s policy: bundles general liability and commercial property.
  • Auto coverage: personal auto policies may exclude business use.
  • Home-based coverage: homeowners policies typically limit or exclude business property and liability. Ask about a home-based business endorsement.
  • Workers’ compensation: required with one employee. A solo owner may buy coverage for themselves but is not required to.
  • Disability insurance: replaces income if you cannot work.

One broker’s customer estimates, not Illinois-specific: general liability averages about $45 a month in that broker’s customer data, with annual premiums roughly $265 to $3,030.

Health insurance

Get Covered Illinois is the state’s marketplace and the only place to get premium tax credits. Open enrollment for 2026 coverage starts November 1. Self-employed people may be able to deduct premiums.

Opening a business bank account

General practice; requirements vary by bank:

  • Sole proprietors typically need photo ID, an SSN or EIN, and the county assumed-name certificate if using a DBA.
  • LLCs typically need filed Articles, an EIN, an operating agreement, and ID.

See assumed-name filings and LLC formation documents.

Keep the money separate

Mixing personal and business funds, or commingling, is a classic reason courts pierce the veil and hold an LLC owner personally liable. It also makes tax records harder to defend. Pay yourself by transfer.

Monthly bookkeeping

Track income, expenses, mileage, and receipts monthly. Common software includes QuickBooks Online, Xero, Wave, and FreshBooks; spreadsheets can work for very simple businesses. These are examples, not endorsements.

The IRS generally recommends keeping records at least 3 years, longer in some cases.
