What Records Should an LLC Owner Keep Throughout the Year?

The IRS requires business owners to keep records that support the income, deductions, and credits reported on their tax returns. But good recordkeeping serves a purpose beyond tax compliance — it gives you accurate financial information throughout the year, not just at filing time.

For LLC owners, the records that matter most fall into a few clear categories. The goal is not to keep everything forever, but to keep the right things in an organized way.

Income Records

Every payment you receive for business services or products should be documented. Income records include:

• Invoices issued to clients or customers
• Receipts for cash payments received
• Bank deposit records showing business income deposited
• 1099-NEC forms received from clients who paid you $600 or more
• Payment processor records (Stripe, PayPal, Square, etc.) showing gross receipts

Note that you owe tax on all income received, not just amounts reported on 1099 forms. If a client pays you $400 — below the 1099 threshold — that income is still taxable and should be recorded.

Business Expense Records

Deductible business expenses reduce your taxable income. To claim a deduction, you need documentation showing the amount, date, and business purpose of each expense.

• Receipts for all business purchases
• Credit card statements for business accounts (with business expenses identified)
• Invoices from vendors and service providers
• Contracts for recurring services (software subscriptions, professional services, etc.)

Home office expenses

If you use part of your home regularly and exclusively for business, you may be able to deduct home office expenses. Keep records of your home's square footage, the square footage of the dedicated office space, and your housing costs (rent or mortgage interest, utilities, insurance).

Vehicle use

If you use a vehicle for business, keep a mileage log recording the date, destination, business purpose, and miles driven for each business trip. The IRS requires contemporaneous records — a log created after the fact is less reliable and harder to defend.

Bank and Credit Card Statements

Monthly statements for all business bank accounts and business credit cards should be retained. These serve as the primary source for reconciling your bookkeeping records and provide a complete picture of money flowing in and out of the business.

If you use a personal account or credit card for any business expenses — which is not recommended — keep those statements as well and clearly identify the business transactions.

Asset Purchase Records

When you purchase equipment, furniture, computers, or other assets used in the business, keep the purchase documentation: receipts, invoices, financing agreements, and any records showing the asset was placed in service for business use.

These records are needed to calculate depreciation deductions over the life of the asset, and to determine gain or loss if you later sell or dispose of it.

Loan and Financing Records

If the business has loans — a business line of credit, equipment financing, or an SBA loan — keep the original loan documents and monthly statements. Interest paid on business loans is generally deductible; you need the statements to document the amount.

Owner Contributions and Draws

Keep records of any money you put into the business (owner contributions) and any money you take out (owner draws). These are equity transactions, not income or expenses, but they need to be documented to maintain accurate books and to track your basis in the business.

Payroll Records (If Applicable)

If your LLC has employees — including yourself if you have elected S-Corporation status — keep all payroll records: time records, pay stubs, payroll tax filings, W-2s, and records of payroll tax deposits. The IRS requires payroll records to be kept for at least four years.

Common Mistakes

• Mixing personal and business transactions in the same account, making it difficult to identify business records
• Discarding receipts for cash purchases, which are often the hardest expenses to document later
• Not keeping a mileage log for business vehicle use, relying instead on memory at year-end
• Keeping records for only one or two years when the IRS standard is three to seven years depending on the situation
