Yes, funding an LLC with personal money is legal and, for most small businesses, the normal way the company gets started. You have two clean ways to do it: make a capital contribution in exchange for an ownership stake, or lend the money to the LLC as a member loan. The choice is not just paperwork. It changes how the money is taxed, whether you have to be repaid, and where you stand in line if the business ever closes.
Capital Contribution or Member Loan
Every dollar you move from your personal account into the business should be classified as one or the other before it lands.
A capital contribution is an investment. If you put $50,000 into a new LLC as equity, that amount increases your capital account and your ownership stake. In a multi-member LLC, each member’s share of profits and losses generally tracks the proportion of their contributions unless the operating agreement says otherwise. There is no repayment schedule. Your return comes from profit distributions or from the eventual sale of the business.
A member loan is different. It creates a creditor relationship: the LLC owes you the money back, usually with interest, on a set schedule. The advantage is priority. If the LLC dissolves, creditors are paid before equity holders see anything, and as a lender you sit with the creditors. The disadvantage is scrutiny. The IRS looks at loans between a member and their own LLC to make sure the terms resemble what an unrelated lender would offer: market-rate interest, a fixed repayment schedule, and a written agreement. If the arrangement looks more like equity dressed up as debt, the IRS can reclassify it, and the tax treatment changes with it.
Most owners use a mix. Enough equity to show the business is genuinely capitalized, and a loan for money you expect to pull back out on a schedule.
Interest Rate Rules If You Lend
A member loan needs to carry at least the Applicable Federal Rate, a minimum interest rate the IRS publishes monthly. For January 2026, the AFRs on annually compounded loans are 3.63% for short-term loans of three years or less, 3.81% for mid-term loans of three to nine years, and 4.63% for long-term loans over nine years.1Internal Revenue Service. Revenue Ruling 2026-02 Check the current month’s rates before you finalize the loan agreement, because the AFR changes every month.
Charge less than the AFR, or nothing at all, and the IRS treats the shortfall as “forgone interest.” Federal law treats that amount as though you transferred it to the LLC and the LLC paid it back to you as interest income, even though no money actually moved. You end up owing tax on interest you never collected. There is one narrow break for member-LLC loans: if the total outstanding balance stays at or below $10,000 and the arrangement is not primarily designed to avoid taxes, the imputed interest rules do not apply.2Office of the Law Revision Counsel. 26 USC 7872 – Treatment of Loans With Below-Market Interest Rates That $10,000 threshold is fixed by statute and does not adjust for inflation.
Contributing Property Instead of Cash
Cash is not the only option. Federal tax law generally lets you contribute property (equipment, vehicles, real estate, inventory) to your LLC without triggering a taxable event at the time of transfer. Neither you nor the LLC recognizes gain or loss on the contribution itself.3eCFR. 26 CFR 1.721-1 – Nonrecognition of Gain or Loss on Contribution The LLC takes on your original cost basis, and the tax bill is deferred until the LLC eventually sells the property.
A few situations break the rule. If the property carries a mortgage or other liability, and the LLC’s assumption of that debt exceeds your basis in the property, you can owe tax on the difference. Contributions that look like disguised sales, where you contribute property and quickly receive cash distributions in return, are also taxable. And contributing services, sometimes called sweat equity, is not a property contribution at all. If you receive an ownership interest in exchange for work, the value of that interest is generally taxable income to you.
Track Your Basis Before You Need It
Your tax basis in the LLC represents your after-tax investment in the business, and it sets the ceiling on how much of the LLC’s losses you can deduct on your personal return in any year. If the LLC loses $80,000 and your basis is only $50,000, you can deduct $50,000. The other $30,000 is suspended until your basis goes back up.
When you contribute cash, your starting basis equals the amount you put in. When you contribute property, your basis equals your adjusted tax basis in that property at the time of contribution. From there, basis rises with additional contributions and your share of LLC income, and falls with distributions you take and your share of LLC losses. An increase in your share of the LLC’s liabilities is treated as an additional cash contribution and also raises basis.4Internal Revenue Service. Partners Outside Basis
Basis is the first hurdle for deducting losses, but not the only one. At-risk rules, passive activity limits, and an overall excess business loss cap for noncorporate taxpayers can all delay a deduction even when you have basis to spare.5Internal Revenue Service. Excess Business Losses Losses blocked by any of these rules carry forward. Without a clean basis record from the start, you have no way to prove your deductions in an audit.
How the Funding Choice Interacts With Self-Employment Tax
By default, a single-member LLC is taxed as a sole proprietorship: you report the business on Schedule C and pay self-employment tax on net earnings through Schedule SE.6Internal Revenue Service. Single Member Limited Liability Companies A multi-member LLC is taxed as a partnership, and each member gets a Schedule K-1.7Internal Revenue Service. LLC Filing as a Corporation or Partnership Members active in the business owe self-employment tax on their distributive share of income.8Internal Revenue Service. Entities 1
A common misconception: structuring your funding as a loan rather than equity does not reduce self-employment tax on the LLC’s profits. Net income flows through to the members regardless of how the business was funded. What the loan structure does is keep principal and interest separate from the profit channel. Interest you receive is ordinary income, not self-employment income, and principal repayments are not income at all.
An LLC can also elect to be taxed as a C corporation using Form 8832, or as an S corporation using Form 2553, which changes how distributions and compensation are handled.9Internal Revenue Service. About Form 8832, Entity Classification Election These elections have qualification rules and deadlines and are worth running past a tax professional before filing.
Put the Structure on Paper
The operating agreement is where the funding structure becomes official. For capital contributions, spell out each member’s initial contribution, how future contributions will be handled, and whether contributions set ownership percentages or the members have agreed on a different allocation. Address whether and how a member can withdraw capital, including notice periods, valuation, and any buyout rights. State default rules on capital withdrawal vary, and a silent operating agreement leaves you stuck with whichever default your state has picked.
For member loans, the operating agreement should authorize the LLC to borrow from its members and refer to a separate loan agreement. The loan agreement itself has to look like a real commercial document: stated principal, interest rate at or above the AFR, repayment schedule, and default terms. This is the documentation the IRS will ask for if it questions whether the loan is genuine.
For larger contributions or loans, add a short member resolution: the company name, the date, a description of the action (for example, accepting a $25,000 capital contribution from a specific member), and the signatures of the members who approved it. Resolutions are cheap to produce and hard to argue with later.
Keep the Liability Shield Intact
The reason to form an LLC is that the business’s debts stay with the business. That protection is not automatic. It holds only if you treat the LLC as a separate entity. When owners blur the line, courts can pierce the veil and hold them personally responsible for the LLC’s obligations.10Nolo. LLCs and Limited Liability Protection
Commingling funds is the fastest way to lose the shield. Open a dedicated business bank account and route every business transaction through it. When you make a capital contribution, transfer the money from your personal account to the business account and record it. When you take a distribution, do the same in reverse. Paying personal bills from the LLC’s account, even occasionally, gives a creditor’s attorney the argument that the LLC is just your alter ego.
Undercapitalization also matters. Forming an LLC with $500 to run a business that clearly requires $50,000 lets a court treat the entity as a shell. There is no universal minimum. Courts look at whether the funding was reasonable given the type of business and the risks involved, and some have treated adequate capitalization as an ongoing obligation rather than a one-time check at formation.
The everyday habits carry the same weight. Keep accurate books. Document major decisions in writing. File annual reports and pay state fees on time; administrative dissolution strips your protection entirely.
What Happens If the LLC Closes
The funding choice pays off, or fails to, at dissolution. Under the default rules in the Revised Uniform Limited Liability Company Act, which a majority of states have adopted or adapted, the LLC’s assets pay creditors first, and that includes members who are creditors because they made loans to the business. Whatever is left goes to members: first to return unreturned capital contributions, then in proportion to distribution rights.11Bureau of Indian Affairs. Harmonized Revised Uniform Limited Liability Company Act
If you funded the LLC with a mix of equity and a loan, you have a better shot at recovering the loan portion when the business winds down. Your capital contribution only gets paid from what remains after all creditors, including you as a lender, are satisfied. If assets fall short, capital contributions can be reduced or wiped out. An operating agreement can rearrange the payout order among members but generally cannot put equity holders ahead of outside creditors.
Records to Keep, and for How Long
For every contribution or loan payment, record the date, the amount, and whether it was a capital contribution, a loan advance, or a loan repayment. Keep the supporting paper: bank statements showing the transfer, signed loan agreements, member resolutions, and any correspondence about the terms. For a multi-member LLC taxed as a partnership, each member’s capital account is tracked on the Schedule K-1.7Internal Revenue Service. LLC Filing as a Corporation or Partnership
The IRS requires records supporting income, deductions, and credits for at least three years after filing. Underreport income by more than 25%, and the retention period stretches to six years. Never file, or file fraudulently, and there is no time limit. Records tied to contributed property should be kept until the statute of limitations runs on the year the LLC disposes of that property, because you will need them to compute gain or loss.12Internal Revenue Service.
