What is tax-risk management for a small business?

It's the practice of identifying where your business is exposed to additional tax, penalties, or interest — across payroll, classification, entity structure, and return positions — and reducing that exposure before it turns into an audit or a notice. It's proactive rather than reactive: you build documentation and controls now instead of scrambling after a letter arrives.

How long can the IRS go back to audit my return?

The general statute of limitations on assessment is three years from the date you file (IRC Section 6501). It extends to six years if you omit more than 25% of gross income, and there is no time limit at all for a return that is fraudulent or never filed. That's why keeping records for at least the full look-back window matters.

What is the accuracy-related penalty?

Under IRC Section 6662, the IRS can add a 20% penalty on the portion of an underpayment attributable to negligence, disregard of the rules, or a substantial understatement of income tax. Solid records and a reasonable, supportable position are the main defenses against it.

How does having multiple entities increase tax risk?

Each entity — an S-corp, a partnership, a rental LLC — has its own filing obligations, its own deadlines, and its own late-filing penalties. Related-party transactions between them (loans, management fees, rent) must be documented and priced reasonably, or the IRS can recharacterize them. More entities means more surfaces where a small oversight becomes a real exposure.
