LLC Bookkeeping: What Records You Need and How to Keep Them

Forming an LLC is one of the smartest moves a small business owner can make. It separates your personal assets from your business liabilities — meaning if your business gets sued or can't pay its debts, your personal bank account and home are generally protected.

But that protection isn't automatic. It depends on how you run the business. And one of the most important things you can do to preserve it is keep your finances clean and separate.

Here's what LLC bookkeeping actually requires.

Before we get into the mechanics of bookkeeping, this is the rule that matters most: never mix personal and business finances.

Open a dedicated business checking account and use it exclusively for business income and expenses. Get a business credit card. Pay yourself from the business account — don't just use business funds for personal purchases.

Commingling funds is the fastest way to lose your LLC's liability protection. Courts call it "piercing the corporate veil," and it means your personal assets are no longer protected. It also makes your bookkeeping a nightmare.

Every dollar that comes into your business needs to be recorded. This includes:

• Invoices and receipts for services or products sold
• Bank deposits
• PayPal, Stripe, Venmo, or other payment platform records
• Any other source of business income

In QuickBooks, income is recorded when you create an invoice (accrual basis) or when you receive payment (cash basis). Most small LLCs use cash basis accounting.

Every business expense needs to be documented with a receipt or record. The IRS requires you to be able to substantiate deductions if audited. Categories to track:

• Office supplies and equipment
• Software subscriptions
• Professional services (legal, accounting)
• Marketing and advertising
• Vehicle and mileage (if used for business)
• Home office (if applicable)
• Business meals (50% deductible)
• Travel

Keep digital copies of receipts. QuickBooks has a receipt capture feature; you can also use a dedicated app like Dext or Hubdoc.

Every account needs to be reconciled monthly — meaning every transaction in QuickBooks matches a transaction on your actual bank statement. This is how you catch errors, duplicate entries, and missing transactions.

If you're not reconciling monthly, your books aren't reliable.

If your LLC has W-2 employees, you need to keep payroll records including hours worked, wages paid, taxes withheld, and payroll tax filings. These records must be kept for at least 4 years.

Note: if you're a single-member LLC taxed as a sole proprietor, you don't run payroll for yourself — you take owner's draws instead.

As an LLC member, you take money out of the business as an "owner's draw" rather than a salary (unless you've elected S-Corp taxation). These draws need to be recorded in QuickBooks as equity withdrawals — not as business expenses.

Recording draws as expenses is a common mistake that makes your P&L look worse than it is and creates problems at tax time.

Single-member LLCs are taxed as sole proprietors by default. Your business income and expenses flow to Schedule C on your personal return. Bookkeeping is relatively straightforward.

Multi-member LLCs are taxed as partnerships by default. Each member's share of income and expenses flows to a K-1, which goes on their personal return. Bookkeeping needs to track each member's capital account and distributions separately.

Both can elect to be taxed as an S-Corp, which adds payroll requirements (see our S-Corp bookkeeping guide).

A proper QuickBooks setup for an LLC includes:

• Chart of accounts tailored to your industry
• Owner's equity accounts (capital contributions, draws)
• Correct tax mapping for each account
• Bank and credit card feeds connected
• Opening balances entered from your actual bank statements

Getting this right from the start saves significant cleanup work later. If you're starting fresh or your current setup is a mess, a QuickBooks setup or cleanup is the fastest path to clean books.

At year-end, your bookkeeper or tax preparer will need:

• Reconciled books through December 31
• A list of any assets purchased during the year (for depreciation)
• 1099 information for contractors paid $2,000 or more
• Any loans to or from the business

The cleaner your books are throughout the year, the faster and cheaper your tax preparation will be.
