There are several ways to finance your business, and most owners end up using a mix: personal savings, loans from family, bank or SBA debt, lines of credit, outside investors who take equity, crowdfunding, and government grants. The right combination depends on how much you need, how fast, how much ownership you’re willing to give up, and whether you can afford to carry debt. Every path has its own legal rules and tax consequences, and the cost of picking the wrong one is usually paid later, not up front.
Paying For It Yourself
Self-funding is the most common starting point. You use personal savings, sell non-retirement assets, or plow early revenue back into the company. You keep full ownership, carry no debt, and answer to no one. The ceiling is whatever you can personally afford.
One rule matters from day one, whether you incorporate or not: keep personal and business money separate. Open a dedicated business bank account and route every business expense and deposit through it. Writing yourself a check from the business account to cover a personal bill, or dropping business revenue into your personal account, creates what courts call commingling. If a creditor later sues the company and can show you treated it as your personal account, a court can pierce the corporate veil and hold you personally liable for business debts. Your home and personal savings become fair game. The fix is boring and effective: two accounts, clean records, no exceptions.
Using Retirement Funds Through a ROBS
Some owners tap 401(k) or other qualified retirement funds through a Rollover for Business Startups (ROBS) without paying the early withdrawal penalty. The structure is specific: you create a new C corporation, establish a retirement plan under it, roll existing retirement funds into that new plan, and use those plan assets to buy stock in the C corporation.1Internal Revenue Service. Rollovers as Business Start-Ups Compliance Project The business ends up with working capital and no distribution occurred on paper, so there’s no immediate tax hit.
The IRS calls ROBS arrangements “questionable” and audits them. The entity must be a C corporation; an LLC or S corporation won’t work. The plan is subject to prohibited transaction rules, which bar using plan assets for personal benefit, lending from the plan to yourself, or leasing personal property to the business through it.2Internal Revenue Service. Retirement Topics – Prohibited Transactions A violation can disqualify the whole plan and trigger taxes plus penalties on the full balance.
ROBS plans also require annual Form 5500 filings regardless of plan size, because the plan owns the business and the small one-participant exemption doesn’t apply. A missed filing can cost $250 per day, up to $150,000 per year.2Internal Revenue Service. Retirement Topics – Prohibited Transactions If you go this route, use a plan administrator who specializes in ROBS. Most of the trouble comes from people who set up the structure and then forget the ongoing compliance.
Borrowing From Friends and Family
Loans from people who already believe in you are common and easy to mishandle. The IRS pays attention to loans between individuals, and sloppy structuring creates tax problems on both sides.
Federal law treats any loan charging less than the applicable federal rate (AFR) as a below-market loan. When that happens, the IRS imputes the missing interest: the lender is treated as if they received interest income (even though they didn’t), and the shortfall is treated as a gift from lender to borrower.3Office of the Law Revision Counsel. 26 USC 7872 – Treatment of Loans With Below-Market Interest Rates The lender owes income tax on phantom interest, and large enough loans eat into the lender’s lifetime gift tax exclusion.
There’s a $10,000 de minimis exception. If total outstanding loans between you and the lender stay at or below $10,000, the imputed interest rules don’t apply. That exception disappears if the loan is used to buy income-producing assets, which a business almost always is.3Office of the Law Revision Counsel. 26 USC 7872 – Treatment of Loans With Below-Market Interest Rates For loans between $10,000 and $100,000, imputed interest is capped at the borrower’s net investment income for the year.
Put every family loan in writing. A proper promissory note includes the amount, an interest rate at or above the current AFR, a repayment schedule, and consequences for missed payments. The IRS publishes updated AFR figures monthly. Charge at least that rate, keep records of every payment, and skip the handshake.
SBA and Bank Loans
Debt financing lets you keep full ownership in exchange for an obligation to repay principal plus interest. For small businesses, the Small Business Administration backs several loan programs that reduce lender risk and open doors a conventional bank loan wouldn’t.
SBA 7(a) Loans
The 7(a) program is the SBA’s flagship. The SBA doesn’t lend directly; it guarantees a portion of loans issued by approved private lenders. For loans under $150,000, the SBA guarantees up to 85%. Above that, the guarantee drops to 75%. The maximum 7(a) loan is $5 million.4U.S. Small Business Administration. Types of 7(a) Loans
The Small Business Act authorizes these guarantee programs and allows the SBA to work with banks through participation agreements.5Office of the Law Revision Counsel. 15 USC Ch. 14A – Aid to Small Business Lenders set their own credit standards on top of SBA requirements. Expect to show federal income tax returns, a personal financial statement, a list of existing debts, formation documents, and a business plan that explains how you’ll use the money and repay it. Most lenders want a personal credit score in the mid-to-upper 600s, strong cash flow, and collateral.
SBA 504 Loans
If you need money for real estate, construction, or long-lived equipment, the 504 program is built for that. The loan is structured as a partnership: a conventional lender covers about 50% of the project cost, a Certified Development Company backed by the SBA covers up to 40%, and you put in at least 10%. The maximum SBA-backed portion is $5.5 million.6U.S. Small Business Administration. 504 Loans
SBA Microloans
For smaller needs, SBA microloans provide up to $50,000 with a maximum repayment term of seven years.7U.S. Small Business Administration. Microloans They’re issued through nonprofit intermediary lenders and often come with business training. A microloan is often the realistic choice for an early-stage business that needs modest capital and lacks the track record for a standard bank loan.
Liens on Your Assets
With a secured business loan, the lender will almost always file a UCC-1 financing statement with your state’s Secretary of State. The filing creates a public record of the lender’s security interest in your business assets, which can include equipment, inventory, or accounts receivable. If you default, the lender with a filed UCC-1 generally has priority over other creditors in claiming those assets. If you later seek more financing, the next lender will see the existing UCC filing, and that can shrink your borrowing capacity or raise your rate.
Lines of Credit and Short-Term Financing
Not every funding need fits a one-time loan. Seasonal businesses, companies waiting on customer payments, and anyone with uneven cash flow often need flexible access to money rather than a single lump sum.
Business Lines of Credit
A line of credit works like a credit card. You’re approved for a maximum, draw what you need, repay it, and draw again. You only pay interest on the outstanding balance. That makes it useful for payroll during a slow month, bridging the gap between invoicing and collection, or absorbing unexpected expenses. Rates are typically higher and more variable than term loans. Pick a term loan when you know exactly how much you need and what you’re buying; pick a line of credit when you need a safety net.
Invoice Factoring
If your business invoices other companies and waits 30, 60, or 90 days for payment, invoice factoring converts unpaid invoices into immediate cash. You sell the invoices to a factoring company, which advances roughly 70% to 90% of face value upfront. When your customer pays, the factoring company sends you the rest minus a fee that typically runs 2% to 5% of the invoice total.
Factoring is technically an asset sale, not a loan, so it doesn’t add debt to your balance sheet. The factor also collects payment from your customer directly, which can be a relief or a problem depending on how you want your clients handled. Approval depends more on your customers’ creditworthiness than yours.
Merchant Cash Advances
A merchant cash advance gives you a lump sum in exchange for a percentage of future sales, usually collected daily or weekly through automatic deductions. These are not technically loans, which means they often sit outside traditional lending regulations. A growing number of states now require providers to disclose total cost, repayment terms, and an annualized rate before you sign. The effective annual cost can be extremely high compared to conventional lending. Treat merchant cash advances as a last resort and read every disclosure before agreeing.
Equity Financing and Private Investors
Equity financing means selling part of your company to investors in exchange for capital. You don’t repay the money, but you give up ownership, and investors share in future profits or losses. Angel investors are generally wealthy individuals who invest at the earliest stages; venture capital firms invest larger amounts in businesses that already show traction.
Regulation D Exemptions
Selling ownership in a company is a securities transaction regulated under the Securities Act of 1933. Most startups don’t register with the SEC. They rely on Regulation D exemptions that allow private placements. Two rules dominate.
Rule 506(b) lets you raise an unlimited amount, but you cannot advertise or broadly solicit investors. You may include up to 35 non-accredited investors, each of whom must be financially sophisticated enough to evaluate the risks. In practice, most 506(b) offerings stick to accredited investors only.8U.S. Securities and Exchange Commission. Private Placements – Rule 506(b)
Rule 506(c) lets you advertise openly and solicit anyone, but every investor who actually purchases must be accredited, and you must take reasonable steps to verify their status. Verification can include reviewing tax returns, bank statements, or getting written confirmation from a broker-dealer or CPA.9U.S. Securities and Exchange Commission. Assessing Accredited Investors Under Regulation D
Who Counts as an Accredited Investor
To participate in most Regulation D offerings, an individual must meet one of these thresholds: annual income above $200,000 (or $300,000 jointly with a spouse or partner) for the past two years with a reasonable expectation of maintaining it, or net worth above $1 million excluding the value of a primary residence.10U.S. Securities and Exchange Commission. Accredited Investors Certain professionals, including holders of Series 7, 65, or 82 licenses, also qualify regardless of income or net worth.
What Investors Will Ask For
Equity investors do extensive due diligence before writing a check. Expect requests for your balance sheet, profit and loss statements, any pending litigation or regulatory issues, intellectual property filings, prior stock issuances, and all material contracts. Negotiations usually start with a term sheet laying out valuation, the percentage being sold, and the rights attached to the new shares. The final deal is documented through a stock purchase agreement and typically covers board seats, voting rights, and liquidation preferences that determine who gets paid first in a sale or shutdown. Keep a clean capitalization table from the start. Sloppy cap tables slow down deals and investors notice.
Crowdfunding
Crowdfunding raises money from a large number of people, usually through an online platform. Rewards-based crowdfunding gives backers a product or perk, not ownership. Equity crowdfunding gives backers actual shares. The legal framework matters most on the equity side.
The JOBS Act created Regulation Crowdfunding (Reg CF), which allows a company to raise up to $5 million in a 12-month period from both accredited and non-accredited investors.11U.S. Securities and Exchange Commission. Regulation Crowdfunding It’s the rare securities exemption that opens the door to everyday investors.
To launch a Reg CF offering, you file Form C with the SEC describing your business, your financial condition, and how you plan to use the proceeds.11U.S. Securities and Exchange Commission. Regulation Crowdfunding Non-accredited investors face annual caps on how much they can invest across all crowdfunding offerings, based on income and net worth. Every offering must run through an SEC-registered intermediary, either a broker-dealer or a funding portal, and any promotional materials must be filed with the SEC. After the offering closes, you file annual reports with the SEC and make them available to investors.
One detail that catches companies off guard: Reg CF preempts state-level securities registration, but some states still require notice filings and filing fees before you can offer securities to their residents. Check your intermediary’s state compliance guidance before launching.
Government Grants
Grants don’t require repayment and don’t dilute ownership. Competition is fierce, eligibility is narrow, and the application work is heavy.
The Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) programs direct federal research dollars to small businesses developing innovative technology.12Small Business Innovation Research (SBIR). About SBIR and STTR Eleven federal agencies participate, including the Department of Defense, the National Institutes of Health, and the National Science Foundation. Funding comes in phases: Phase I awards typically run up to around $300,000 for a feasibility study, and Phase II awards can reach roughly $2 million for full research and development. STTR awards require a nonprofit research partner, with at least 30% of the budget going to the research institution and at least 40% to the small business. SBIR awards don’t require a partner.
Applying starts with registering in the System for Award Management (SAM), which requires a Unique Entity Identifier and your NAICS industry codes. The application itself is a detailed technical and commercial proposal. If you win, expect strict compliance: rigorous accounting, periodic progress reports, and clear documentation of every dollar spent. Misusing grant funds can lead to revocation and legal consequences.
How Each Financing Method Hits Your Taxes
The financing choice follows you to tax season. A few rules matter most.
Borrowed money isn’t taxable when you receive it, because you have an offsetting obligation to repay. That’s true whether the loan comes from a bank, the SBA, or a family member. If a lender later forgives or cancels the debt, the forgiven amount usually becomes taxable income in the year it’s cancelled.
Interest paid on business loans is generally deductible, but there’s a ceiling. Section 163(j) of the Internal Revenue Code caps the deduction for business interest expense at 30% of your adjusted taxable income, plus any business interest income. The One, Big, Beautiful Bill Act changed how adjusted taxable income is calculated for tax years beginning after December 31, 2025, particularly for businesses with international operations.13Internal Revenue Service. Questions and Answers About the Limitation on the Deduction for Business Interest Expense Small businesses with average annual gross receipts of $30 million or less over the prior three years are generally exempt from the cap.
If you use financing to buy equipment, vehicles, or other qualifying business assets, the Section 179 deduction lets you write off the full cost in the year you place the asset in service rather than depreciating it over years. For tax years beginning in 2026, the maximum Section 179 deduction is $2,560,000, and it begins to phase out when total qualifying purchases exceed $4,090,000.
Money raised by selling equity isn’t taxable to the business. The investor gets ownership, the company gets capital, and no loan or interest deduction is involved. Government grants, in contrast, are generally taxable income unless a specific exclusion applies, so plan the tax bill into your use of the money.
