How to Manage Your LLC or Corporation: Documents You Need

Managing an LLC or corporation means keeping the right documents in order — not just at formation, but throughout the life of your business. The core documents include your governing agreement or bylaws, your Employer Identification Number (EIN), ownership records, meeting minutes or resolutions, and state annual report filings.

LLCs need an operating agreement; corporations need bylaws. These documents set the internal rules for how your business runs — who has authority, how decisions get made, how profits are split, and what happens if an owner leaves. They're the foundation everything else is built on.

An LLC operating agreement should cover member management authority, voting rights, capital contributions, profit and loss allocation, and how the business would be dissolved if needed. Not every state legally requires one, but without it, your LLC falls back on default state rules that may not reflect what you and your co-owners actually agreed to.

Corporate bylaws serve a similar function for corporations. They typically address board of directors meetings, shareholder meetings, officer roles and duties, stock issuance, and how the bylaws themselves can be amended. Most states require corporations to adopt bylaws, and they're often needed when opening a business bank account or applying for financing.

Most business owners don't realize how much weight these documents carry until they need them — in a dispute, a bank application, or a tax audit.

An Employer Identification Number (EIN) is a federal tax ID assigned by the IRS. Both LLCs and corporations need one — even if you have no employees — for tax reporting, opening a business bank account, and hiring contractors. You apply using IRS Form SS-4, and online applications are processed immediately.

You can apply for an EIN at irs.gov/ein. The online application is available Monday through Friday, 7 AM – 10 PM ET. If you apply by fax, expect about 4 business days. Mail applications take 4 to 5 weeks.

Once issued, the IRS sends a CP575 notice confirming your EIN. Keep this document — banks and state agencies will ask for it. If you lose it, you can call the IRS Business and Specialty Tax Line to retrieve your number, but you won't get a duplicate CP575.

LLCs need a membership interest ledger tracking each member's ownership percentage and capital contributions. Corporations need a stock ledger listing every shareholder, the number of shares they own, and any transfers or cancellations. These records are how you prove who owns what — and they matter in disputes, sales, and audits.

For LLCs, the operating agreement typically documents initial membership interests. But as ownership changes — a member buys out another, or a new member joins — you need to update the ledger and document the transfer in writing. Keeping this current is one of those tasks that's easy to skip and expensive to reconstruct later.

Corporations must record every issuance, transfer, and cancellation of stock certificates. The SEC provides guidance on recordkeeping requirements for small businesses, and most state corporation statutes require the stock ledger to be available for shareholder inspection.

Corporations are required by most states to keep minutes of all shareholder and board of directors meetings. LLCs generally don't have a statutory requirement for meeting minutes unless their operating agreement calls for it. That said, documenting major decisions in writing is a good practice for any business — LLC or corporation.

For corporations, meeting minutes are the official record of decisions made during meetings. Corporate resolutions — formal documents recording specific actions approved by the board or shareholders — go hand in hand with minutes. You'll need both when making significant decisions like opening a bank account, taking on debt, or issuing new shares.

LLCs have more flexibility here. If your operating agreement doesn't require formal meetings, you can document decisions through written consents instead. Either way, keeping a paper trail of major decisions protects you if the business is ever audited or if a dispute comes up between members.

Most states require LLCs and corporations to file annual or biennial reports with the secretary of state to stay in good standing. These reports typically confirm your business's legal name, address, registered agent, and principal office. The filing frequency, due dates, and fees vary by state.

Missing an annual report filing can result in the state administratively dissolving or suspending your business — which means you lose the liability protection and legal standing you formed the entity to get. Some states give you a grace period; others act quickly. Check your state's secretary of state website for your specific deadline.

Beyond annual reports, some states require additional filings when your business information changes — like a new registered agent, a change of address, or updated officer or member information. These aren't optional updates. Keeping your state records current is part of staying compliant.

The tax forms your business files depend on how it's classified with the IRS. A single-member LLC taxed as a sole proprietorship reports business income on Schedule C of Form 1040. A multi-member LLC taxed as a partnership files Form 1065. A corporation files Form 1120, and an S corporation files Form 1120-S.

If your LLC or corporation has employees, you'll also file Form 941 quarterly to report payroll taxes, and issue W-2s to employees at year end. If you pay contractors $600 or more in a year, you'll need to file Form 1099-NEC for each one.

Tax classification isn't always set at formation. LLCs can elect to be taxed as a corporation by filing Form 8832 with the IRS, or as an S corporation by filing Form 2553. A tax professional can help you figure out which classification makes the most sense for your situation.

Good recordkeeping isn't about being meticulous for its own sake — it's about having what you need when something goes wrong or when an opportunity comes up. A bank asking for your operating agreement, an auditor asking for meeting minutes, or a buyer asking for your ownership history: these moments reward the business owners who kept their records current.

Keep your formation documents, EIN confirmation, operating agreement or bylaws, and ownership records in one place — physical or digital. Update them when anything changes. Don't let ownership transfers, officer changes, or amended agreements sit undocumented.

Set a calendar reminder for your state's annual report deadline. Missing it is one of the most common and avoidable ways businesses lose their good standing. Your state's secretary of state website will have the exact due date and fee for your entity type.

If you have employees or contractors, keep copies of all W-2s, 1099-NECs, and payroll tax filings. The IRS can request records going back several years, and having them organized saves real time and money if that happens.
