Before you take a dollar from a family member or friend, both of you need to agree on what that money actually is. There are three possibilities: a gift (no expectation of repayment), a loan (repayable with or without interest), or an investment (equity in the business). Each has different legal, tax, and relational implications. The most common source of conflict is that the person giving it and the person taking it had different answers to this question.
A parent who writes their child a $50,000 check thinking “I’m helping them get started” and expecting nothing back is making a gift. If the child treats it as an investment and later gives their parents a 3% stake in the company, that parent might feel confused — they never thought they were an investor, they were just helping family. The relationship gets complicated, and it didn’t have to.
Have an explicit conversation before you take the money. What do they expect in return? Nothing? Repayment? Equity? Interest? Are they in a financial position to lose this money entirely if the business fails? Make sure both sides are honest about these questions.
A gift requires no legal documentation but does have tax implications. In 2024, the annual gift tax exclusion is $18,000 per donor per recipient. A parent can give you $18,000 per year without gift tax implications. Amounts above that count against the lifetime exemption ($13.61 million in 2024), though very few people actually owe gift tax because of the large lifetime exemption.
For the recipient, gifts are not taxable income — you don’t owe income tax on money someone gives you. But you also have no legal obligation to repay it, which means if the business succeeds, the giver has no claim to that success.
If both parties genuinely understand and agree that the money is a gift with no expectation of return — financial or relational — then a gift is clean. The problem is when “it’s a gift, don’t worry about it” from a parent actually carries an implicit expectation of preferential treatment or repayment if the business succeeds. Be honest about expectations before the money changes hands, not after.
If someone is lending you money and expects to be repaid, treat it like a real loan. The IRS has rules about “below-market loans” between family members: if you borrow money without charging sufficient interest, the IRS can recharacterize the arrangement and create phantom income and gift tax issues. The minimum required interest rate is the Applicable Federal Rate (AFR), which is published monthly by the IRS.
More importantly, document the loan with a promissory note. A promissory note specifies the loan amount, interest rate, repayment schedule, and what happens if you default. Without documentation, the lender can’t deduct a loss if the loan goes bad (it would be treated as a gift). With documentation, a defaulted loan can be treated as a bad debt deduction.
The hardest part of family loans isn’t the paperwork — it’s the repayment pressure. A loan from a bank won’t call you at Thanksgiving asking about repayment. A family loan creates an ongoing relational dynamic that’s affected by every missed payment or delayed repayment. If the business goes through a rough period and you can’t make payments, that stress lives in your family relationships in a way bank debt doesn’t. Be realistic about this before you borrow from family.
If someone is giving you money in exchange for equity in the business, they’re an investor. Even if they’re your uncle. Even if it’s $5,000. Treat every investor — regardless of relationship — with the same documentation you’d use for any other investor.
For a startup, the standard vehicle is a SAFE (Simple Agreement for Future Equity). YC’s post-money SAFE template is free, well-understood, and appropriate for most friends-and-family investments. It gives the investor the right to equity when the company raises a priced round. For amounts too small to make a SAFE practical, you might use a simple loan that converts, but get legal advice on structuring this.
Taking investment money, even from people you know, is technically a securities transaction. There are federal and state rules that apply, and they exist to protect both you and the people investing in you. Most small raises from friends and family can be structured in a way that complies with these rules without much complexity. The important thing is to be aware that these rules exist before you start accepting investment money, not after. Agapius can walk you through the basics of how early fundraising compliance works.
The most dangerous situation is taking money without any documentation or explicit agreement about what it is. This seems fine at the time — “we’re family, we trust each other” — but creates multiple problems as the business evolves.
If the business succeeds and you later raise venture capital, investors will do due diligence on your cap table. Undocumented equity obligations hanging over the company — money you took years ago that someone believes entitles them to equity — are a red flag. Investors will want clean representations about who owns what and what obligations the company has. An undocumented agreement with a family member can actually block or delay a deal.
If the business fails, undocumented money creates ambiguity about whether your family member has a legal claim. If the family member needs that money back, the absence of documentation makes the situation much harder to navigate — both legally and relationally.
The most important protection is a clear upfront conversation. Tell the person what you’re building, how you’re planning to use the money, the realistic probability that the business fails, and what you’re offering in return (if anything). If someone loves you and wants to support you, they can do that and also understand what they’re actually signing up for.
The goal is to make sure that the support is based on a shared understanding of what it means. A $25,000 investment from a friend who can genuinely afford to lose it and understands they might — that’s a clean, healthy arrangement. A $50,000 loan from a parent who is drawing down their retirement savings and expects full repayment with interest — that might create relational pressure that makes the business harder to run.
After the conversation, document what you agreed to. Even if it’s a gift, a simple email saying “I appreciate the $20,000 — we’ve agreed this is a gift with no expectation of repayment” creates a record that can prevent future misunderstandings. It doesn’t have to be a formal legal document for every small gift — it just needs to be clear.
For genuine gifts under $18,000 from a single donor: a clear conversation and a confirming email or text. No formal document needed.
For loans: always use a promissory note, regardless of amount or relationship. The note protects both sides and allows the lender to deduct a loss if things go wrong.
For investments (equity exchanges): always use proper documentation. A SAFE (Simple Agreement for Future Equity) is the most common instrument for early-stage investments, and standard templates are freely available online. For straightforward situations, the template may be all you need. If the structure is more complex, or if you’re raising from multiple people, professional guidance can help you get it right.
If you’re raising a meaningful amount (say, $50,000 or more) from multiple friends and family, treat it like a proper fundraise with a single document that all investors sign, a clear description of the terms, and compliance with applicable securities exemptions.
