LLC Bookkeeping: How to Keep Your Books in Order

LLC tax basics

An LLC (Limited Liability Company) is a legal entity created at the state level. But the IRS doesn't have a specific tax classification for LLCs. Instead, it treats them differently depending on how many members they have and what tax election you've made:

• Single-member LLC (default): Treated as a sole proprietorship. You file Schedule C on your personal 1040. The IRS considers the LLC a "disregarded entity" for tax purposes.
• Multi-member LLC (default): Treated as a partnership. The LLC files Form 1065 and issues K-1s to each member. Each member reports their share on their personal return.
• LLC with S-corp election: Treated as an S-corporation. Files Form 1120-S. Members who work in the business must receive a "reasonable salary" via payroll.
• LLC with C-corp election: Treated as a C-corporation. Files Form 1120. Rarely used for small businesses due to double taxation.

Most small LLCs are single-member, taxed as sole proprietorships. The LLC structure provides liability protection, but the tax treatment is identical to operating without an LLC. You're still filing Schedule C, still paying self-employment tax, still making quarterly estimated payments.

The LLC doesn't change your tax bill. It changes your legal liability. That distinction matters.

Single-member LLC bookkeeping

If you're a single-member LLC taxed as a sole proprietorship (the default), your day-to-day bookkeeping is identical to any sole proprietor:

• Track all income and expenses through your LLC bank account
• Categorize transactions to match Schedule C line items
• Reconcile monthly against your bank statements
• Generate a P&L (income statement) for your CPA
• Report everything on Schedule C attached to your personal Form 1040

The critical difference from operating without an LLC: you MUST keep your LLC finances completely separate from personal finances. This is what maintains your liability protection (the "corporate veil"). If you treat the LLC bank account like your personal checking account, a court can "pierce the veil" and hold you personally liable for business debts.

In practice, this means:

• Separate bank account in the LLC's name
• Separate credit card for business expenses
• All business income deposited into the LLC account
• All business expenses paid from the LLC account
• Personal expenses NEVER paid from the business account
• Money for personal use transferred as a formal owner's draw

Multi-member LLC bookkeeping

Multi-member LLCs are taxed as partnerships by default, which adds several layers of complexity to bookkeeping:

Capital accounts: Each member has a capital account that tracks their equity in the LLC. It starts with their initial contribution, increases with allocated profits and additional contributions, and decreases with allocated losses and distributions. You must maintain these throughout the year.

Allocation of income and loss: The operating agreement specifies how profits and losses are split among members. Common structures are 50/50, proportional to ownership percentages, or custom allocations based on capital, labor, or other factors. Whatever the agreement says, your books must reflect it.

Distributions: Track every distribution to every member. Distributions don't have to match profit allocation (one partner might take more draws than another), but they should be documented and consistent with the operating agreement.

K-1 reporting: By March 15 each year, the LLC must issue Schedule K-1 to each member showing their share of income, deductions, and credits. Members use this to report on their personal returns.

Filing requirements: Multi-member LLCs file Form 1065 (partnership return) with the IRS. This is an informational return; the LLC itself doesn't pay taxes, but the IRS uses it to verify that members are reporting their share correctly.

Most multi-member LLCs should work with a CPA, at least for the tax return and K-1 preparation. The daily bookkeeping (tracking income and expenses) is the same as any business, but the member accounting and tax reporting requires professional knowledge.

Owner's draws vs. salary

How you pay yourself from your LLC depends on your tax election:

Sole proprietorship / Partnership (default): You take owner's draws. This means you transfer money from the LLC bank account to your personal account. Draws are NOT expenses. They don't reduce your business profit. They're distributions of profit you've already earned and will pay taxes on regardless of whether you take the money out.

How to record draws:

• Categorize the transfer as "Owner's Draw" or "Owner's Distribution"
• Do NOT categorize it as a business expense (this is the most common mistake)
• Track total draws for the year (your CPA needs this)
• Draws reduce your capital account balance but don't affect the P&L

S-corp election: If your LLC has elected S-corp status, members who work in the business MUST receive a W-2 salary. This salary is a legitimate business expense and is subject to payroll taxes (FICA). Profit above the salary can be taken as distributions, which are not subject to self-employment tax. This is the main tax advantage of S-corp election.

How much to draw? There's no rule. Many LLC owners draw monthly based on their personal budget needs. Some draw quarterly after reviewing profitability. The key is to leave enough in the business account to cover expenses and maintain a cash reserve. A common rule of thumb: keep at least 2-3 months of expenses in the business account.

Maintaining the corporate veil

The whole point of an LLC is liability protection. If someone sues your business, they can go after business assets, but not your personal house, car, or savings. This protection only holds if you treat the LLC as a genuinely separate entity.

Courts use several factors to determine whether to "pierce the corporate veil":

1. Commingling of funds. Using the business account for personal expenses (or vice versa) is the #1 factor. Every time you pay for groceries from the LLC account, you weaken your protection.
2. Adequate capitalization. The LLC needs enough money to operate. If you drain all profits immediately and leave the LLC unable to pay its debts, that's a problem.
3. Separate identity. Use the LLC name on contracts, invoices, marketing materials, and business cards. Sign as "[Your Name], Member of [LLC Name]" not just your personal name.
4. Compliance with formalities. File your annual state reports, pay the annual fee, keep your registered agent current, and maintain an operating agreement.
5. Clean records. If you ever get sued, the opposing lawyer's first move is to subpoena your financial records. Clean, separated books that clearly show business vs. personal are your best defense.

Maintaining the veil isn't hard. It's just discipline. Keep things separate, keep records clean, and treat the LLC like what it is: a separate entity from you.

S-corp election for LLCs

Once your LLC's net profit consistently exceeds $50,000-$60,000, an S-corp election can save significant taxes. Here's the quick version:

How it works: You file Form 2553 with the IRS to elect S-corp status. The LLC continues as an LLC under state law, but the IRS treats it as an S-corp for tax purposes. Members who work in the business must receive a W-2 salary through payroll.

The tax advantage: Only the salary portion is subject to FICA/self-employment tax (15.3%). Profit above the salary passes through as a distribution, which is subject to income tax but NOT self-employment tax.

The costs:

• Payroll service: $50-$200/month
• Separate corporate tax return (Form 1120-S): $500-$1,500 from your CPA
• More complex bookkeeping (payroll entries, salary vs. distribution tracking)

When it makes sense: Generally when the SE tax savings exceed the additional costs. At $60K net profit, you save roughly $3,000-$4,000 in SE tax but spend $2,000-$3,000 on payroll and accounting. The break-even is usually around $50,000-$60,000 in net profit, but talk to your CPA because your specific situation matters.

"Reasonable salary" requirement: The IRS requires that your salary be reasonable for the work you do. You can't pay yourself $10,000 and take $90,000 as a distribution. The IRS has flagged S-corps for unreasonably low salaries. Common guidance is to set salary at 50-60% of profit or research comparable salaries for your role.

State filing requirements

LLCs are created at the state level, and each state has its own requirements:

Annual reports: Most states require an annual or biennial report to keep your LLC in good standing. Miss it and your LLC can be administratively dissolved. Fees range from $0 (some states) to $800+ (California's minimum franchise tax).

State taxes: Some states impose additional taxes on LLCs:

• California: $800/year minimum franchise tax plus a gross receipts fee for LLCs earning over $250,000
• New York: Annual filing fee based on gross income ($25-$4,500)
• Most other states: Flat annual fee of $50-$300

Registered agent: Every LLC needs a registered agent in its state of formation. This can be you (if you have a physical address in the state) or a registered agent service ($50-$300/year).

Business licenses: Some cities and counties require separate business licenses or permits. Check with your local government.

Keep a calendar of all state filing deadlines. Missing an annual report is a common and easily preventable mistake that can cost you your LLC's good standing.

Common LLC bookkeeping mistakes

• Treating owner's draws as expenses. When you transfer money from the LLC to your personal account, it's a distribution, not a business expense. Recording it as an expense inflates your deductions and will create problems with the IRS. Use a dedicated "Owner's Draw" category or equity account.
• Not tracking member contributions and draws. You need to know how much each member has put in and taken out. This matters for taxes, for the capital accounts, and especially if the partnership ever dissolves or a member exits.
• Forgetting estimated tax payments. Your LLC doesn't pay taxes directly (it's pass-through). But YOU personally need to pay quarterly estimated taxes on your share of the LLC income. The LLC not paying taxes doesn't mean nobody pays taxes.
• Mixing personal and business expenses. Every personal expense paid from the LLC account weakens your liability protection. Set up a monthly owner's draw for personal needs and keep everything else in the business account.
• Not having an operating agreement. Even a single-member LLC should have one. It documents how the LLC is governed, how profits are distributed, and what happens if the business is sold or dissolved. Without one, your state's default LLC laws govern, and those may not match your intentions.
• Letting the LLC lapse. Forgetting to file your annual state report or pay the franchise tax can result in administrative dissolution. Set a calendar reminder 30 days before each state deadline.
• Not getting an EIN. Single-member LLCs without employees can technically use the owner's SSN, but getting an EIN (free from the IRS) is better practice. It keeps your SSN off forms, and you'll need one anyway if you hire employees, open a business bank account, or elect S-corp status.
