LLC Bookkeeping Requirements: What You Actually Have to Track

There is no federal law telling single-member or multi-member LLCs exactly how to keep books, but the IRS expects records that support your tax return. Most states expect business and personal finances to stay separate if you want your liability shield to hold up. At a minimum, keep a dedicated business bank account, organized income and expense records, and documentation for deductions.

You will not find a federal statute that lays out precisely how an LLC, be it single- or multi-member, is to keep its books. Yet the IRS has an expectation: your records must stand up in support of your tax return. And if you are to have any confidence in your liability shield, most states will want to see a clean line between your business and personal finances. As a bare minimum, that calls for a business bank account of its own, organized income and expense records, and proper documentation for your deductions.

Some founders set up an LLC and figure a bookkeeper will advise them on what the law demands. They are hardly alone in that assumption. More often than not, they are proven wrong when a bank requests financial statements or an accountant asks why personal and business expenses are commingled in a single account. The requirements for an LLC are not as codified as one might suppose, but ignoring them invites trouble at audit time.

We see this question all the time in our work with founders in 175+ countries. Non-resident owners, in particular, tend to think a US LLC operates like a firm in their home country. It does not. We handle the formation and compliance side of things, so we can tell you what actually applies.

What the Law Actually Requires

It is not quite what most people imagine. You won’t see a state statute commanding you to do double-entry bookkeeping or to reconcile on a monthly basis. The obligations come from three quarters, and a founder is apt to be aware of only one.

For one, there is the IRS. Under Section 6001 of the Internal Revenue Code, you are required to have records to substantiate your return. That is non-negotiable whether your LLC is a disregarded entity, a partnership, or has made an S-Corp or C-Corp election.

Then there are the state statutes. They require “adequate” records, though they leave the definition open to interpretation. The Delaware LLC Act, for example, requires an LLC to maintain records to determine members’ financial rights, but it does not prescribe a method.

The third area is where people make a mistake. If you go before a court and your books show no separation between your money and the LLC’s, a judge may decide to pierce the corporate veil. In that event, the LLC is not treated as a separate entity, and your personal assets remain unprotected.

Records Every LLC Should Be Keeping

The kind of records we would have any client put in place are these:

• A business account in the LLC’s name and EIN, not a personal one.
• A log of income, broken down by source or client.
• Expense receipts: the IRS wants to see the business purpose, not just a bank statement.
• Mileage logs with dates and miles for any vehicle use you put on your return.
• All 1099s, issued and received.
• W-2s and 941 filings if you run a payroll.
• Your operating agreement and amendments are filed with permanent records.
• Confirmation of your annual report or franchise tax with the state.

Programs like QuickBooks, Wave, or Xero will do 90 percent of the work for you. What gets overlooked is putting away the receipts. An audit will not be satisfied with a bank or credit card statement on its own. They can tell you where the money went, but nothing about what was actually bought.

How Long to Keep Financial Records

The IRS general rule is three years from the date you filed the return, but that window extends in specific situations:

As a rule of thumb, we advise our clients that seven years is more sensible. State auditors and lenders conducting due diligence have been known to go back further than the IRS. And with digital storage being so inexpensive, there is little point in shredding documents prematurely.

Single-Member LLCs Still Need Real Bookkeeping

This is an area where non-resident founders, in particular, make mistakes. Because a single-member LLC that has not elected to be taxed as a corporation is a disregarded entity for federal tax purposes, the income is reported on the owner’s Schedule C. Some take that as a license to forgo proper bookkeeping since there is no separate LLC return to file.

But being disregarded for tax purposes does not erase the legal distinction. The IRS may be blind to the LLC when you file, but a court will not be if you are sued. Should your books fail to show the LLC as a distinct financial operation, you are giving opposing counsel the ammunition they need to press for alter ego liability. We see it with e-commerce founders all the time. They let their Shopify and Stripe payouts land in a personal account, pay themselves at will, and mix inventory with personal expenses. It is fine until a loan application or a lawsuit comes along; the issue is the lack of separation.

Extra Requirements for Non-Resident Owners

Running an LLC from outside the US brings a few changes. You will need a US bank account; while some major institutions still require you to visit in person, most now work with fintechs such as Mercury, Relay, or Wise Business to open accounts for foreign-owned LLCs with an EIN.

Then there is Form 5472. Foreign-owned single-member LLCs must file this with a pro forma 1120 to detail any transactions with the owner. The IRS has made it clear they will enforce the $25,000 penalty for a missed filing. Your records must account for every transfer between you and the company, not just the customer side.

Do not overlook currency conversion either. When you are using Payoneer or Wise and invoicing in another currency, document the exchange rate. The IRS requires USD on the return and will not accept an estimate when asked to put numbers to the conversion.

Common Bookkeeping Mistakes

The first 90 days are when the trouble often starts, with founders mixing personal and business money. They will form an LLC and then continue to run things through a personal Venmo or checking account in the name of “getting set up,” but the switch never happens. In court, that kind of commingling only looks worse over time.

Then there is the matter of owner draws being put down as a business expense. When you take from the LLC, it is a distribution, not something you can deduct. We see bookkeeping software categorize this incorrectly all the time; it overstates your expenses and understates what you actually owe in taxes.

Selling physical goods means you need a system for sales tax. Most states have an economic nexus threshold these days (around $100,000 in sales or 200 transactions a year) and will require you to register and remit once you hit that mark, physical presence or not. Failing to keep the tax you collect apart from your revenue in your books makes for a headache at filing time.

Some treat state annual report deadlines as a filing matter and not a bookkeeping one, which is a mistake. The two are linked. California, Texas, and Delaware are among the states that demand you stay on top of your franchise tax and annual reports. Let them slip and your LLC could be administratively dissolved, muddying the waters for every financial record tied to the entity.

There is also the false notion that bookkeeping and tax prep are one and the same. A bookkeeper’s job is to track and record transactions over the course of the year; the tax preparer files the return based on that work. If the only contact with an accountant is in March, odds are the bookkeeping was done hastily and incorrectly after the fact.

When You Should Hire a Bookkeeper

It is not always necessary, but the numbers tell you when it is. For a founder with under $50,000 in revenue and straightforward transactions, Wave or QuickBooks Simple Start will do, and it will take maybe a couple of hours a month.

Once you are past that, or if you are dealing with inventory, foreign-owned structures that file Form 5472, or issuing 1099s to contractors, a bookkeeper is a better value. At $200 to $600 a month for a small LLC, they are far less expensive than having an accountant come in at tax time to put right a year of disarray. Accountants will put a much higher price on reconstructing books than a bookkeeper does on maintaining them.
