Illinois Business Power of Attorney: Authority for LLCs, Corporations, and Partnerships

You're the sole member of an LLC that owns three rental properties in Cook County. If you're hospitalized or traveling overseas, who signs the lease renewals? Who deposits the rent checks? Who handles the insurance claim if a tenant causes damage?

Without a power of attorney that specifically covers business operations, the answer may be nobody — and the business stalls until you're available again or a court appoints someone.

Does the Standard Statutory Form Cover Business Operations?

The Illinois Statutory Short Form Power of Attorney for Property (755 ILCS 45/3-3) includes several categories of authority that touch business operations:

• Real property transactions — buying, selling, leasing, managing real estate
• Banking and financial institution transactions — account management, deposits, withdrawals
• Business operating transactions — operating, buying, selling, or liquidating a business
• Insurance and annuity transactions — managing business insurance policies
• Claims and litigation — filing or defending lawsuits on behalf of the principal
• Tax matters — filing business tax returns, dealing with the IRS and Illinois Department of Revenue

If the principal leaves all of these categories intact (doesn't strike them out on the form), the agent has broad authority over the principal's business interests. But "broad authority" under the statutory form is not the same as "complete authority" — and the gaps matter.

Where the Statutory Form Falls Short for Business

LLC Operating Agreements

Most Illinois LLC operating agreements include provisions about who can act on behalf of the company, what happens when a member is incapacitated, and whether a POA agent can step into the member's role. If the operating agreement doesn't address POA authority — or explicitly restricts it — the statutory POA alone may not be enough.

Before relying on a statutory POA for LLC management, check the operating agreement for:

• Incapacity provisions: Does the agreement define what happens when a member becomes incapacitated?
• Transfer restrictions: Can management authority be delegated to a non-member agent?
• Consent requirements: Do other members need to approve the agent's authority?

If the operating agreement is silent on these points, the agent's authority under the statutory POA generally applies. But if the agreement restricts delegation, the POA can't override the contract.

Corporate Resolutions

For Illinois corporations, the board of directors typically controls who has signing authority. A shareholder's personal POA doesn't automatically give the agent authority to act as an officer or director of the corporation.

If you're a sole shareholder and sole director of a small corporation, your POA agent can vote your shares and manage your ownership interest — but corporate governance decisions may require a formal board resolution authorizing the agent to act on behalf of the corporation.

Partnership Authority

For general partnerships, a partner's POA agent can typically exercise the partner's management rights — but the partnership agreement may restrict this. For limited partnerships, a limited partner's POA agent generally cannot assume general partner duties unless the partnership agreement specifically allows it.

What to Put in the Special Instructions

For business owners, the Special Instructions section of the statutory form becomes critical. Consider adding provisions that:

Name the specific business entities: "My agent is authorized to manage and operate [Business Name], Illinois LLC, including signing contracts, managing employees, and conducting banking transactions on behalf of the company."

Address signing authority: "My agent may sign documents, contracts, and agreements on behalf of [Business Name] in my capacity as [Member/Manager/President]."

Cover business banking: "My agent is authorized to access and manage all business bank accounts held in the name of [Business Name] at [Bank Name], including deposits, withdrawals, and electronic transfers."

Set dollar limits if appropriate: "For transactions exceeding $[amount], my agent must consult with [named advisor/attorney/accountant] before proceeding."

Business-Specific vs. Personal POA

Some business owners execute a separate POA that covers only business operations, keeping it distinct from their personal Property POA. This approach has advantages:

• Different agents for different roles: Your spouse may be the right person to manage personal finances, but your business partner or CFO may be better suited to manage business operations
• Cleaner third-party acceptance: Banks that hold business accounts may be more comfortable with a POA that specifically names the business entity
• Limited exposure: A business-only POA doesn't give the agent access to personal accounts, reducing the risk of overreach

The execution requirements are the same — witness, notary, statutory language — regardless of whether the POA covers personal matters, business matters, or both.

Tax Filing Authority for Business

If the principal's business requires filings with the Illinois Department of Revenue, the agent may need to file Form IL-2848 (Illinois Power of Attorney) separately to gain authority to discuss the business's tax matters with the state. The general statutory Property POA covers "tax matters" as a category, but IDOR has its own form and process for granting third-party access to tax accounts.

Similarly, IRS Form 2848 is required for federal tax representation. The statutory POA alone doesn't give the agent standing to speak with the IRS on behalf of the business.
