A family loan is considered a gift by the IRS if it lacks formal documentation, such as a signed promissory note, a set repayment schedule, and a market-rate interest charge (at least the Applicable Federal Rate). Without these, the IRS assumes the money is a gift.
This means you must charge and collect interest following the rules for the applicable federal rate. The minimum interest rate varies based on the length of the loan. If you lend the money at no interest, the IRS can consider the loan a gift, making you liable for gift taxes.
You are not required to disclose this to the IRS. Loans are not income and as such they are not reported to the IRS. If you were to be audited by the IRS, they would likely review your bank statements. During the review of your bank statements they would likely inquire into the source of the funds.
There may be tax implications.
If the money is a loan greater than $10,000, your loved one is required to charge an interest rate in line with IRS guidelines, known as the Applicable Federal Rate (the rate changes every month). Otherwise, the money is considered income that you can be taxed on.
Therefore, if the lender does not have anything in writing signed by the borrower confirming their agreement that the sum of money was a loan to be repaid, the Court will presume that the money was a gift in these circumstances.
The "$100,000 loophole" for family loans refers to a tax rule where lenders avoid reporting imputed interest if the total loan amount (plus any other outstanding loans to that borrower) is $100,000 or less, and the borrower's net investment income is $1,000 or less; otherwise, the lender's taxable imputed interest is limited to the borrower's actual net investment income, avoiding the higher Applicable Federal Rates (AFR) normally required, making it a way to offer lower-interest loans with minimal tax hassle for the family.
It can be difficult to establish whether a payment is a loan or a gift unless there is some sort of written acknowledgement/agreement in place. Even if a loan is to your friends or family, it is advisable to draw up some form of written agreement so that your intentions are clear.
Any interest you charge on the loan is subject to income tax and you must declare this on your self-assessment tax return. The tax you pay on it will depend on your income tax bracket.
Disadvantages
When lending money, a written Loan Agreement or Promissory Note is your best friend. Even if you're loaning money to a friend or family member, it's always a good idea to create a written contract rather than rely on a verbal agreement.
When someone makes a gift, they do not expect repayment. When someone makes a loan, there is an expectation of repayment. The identification or classification of whether monies advanced are a gift or a loan impacts upon both equitable distribution and support determinations in a divorce action.
A gift letter is a legal document stating that funds you received from a relative or friend are a personal gift and not a loan. The donor is generally required to sign the gift letter. A gift letter allows lenders to confirm that funds come from a legitimate source when underwriting a loan.
Yes, you can give your son $100,000 tax-free in 2025 by utilizing the annual gift tax exclusion and your lifetime exemption, but you'll need to report the gift to the IRS on Form 709 since it exceeds the $19,000 annual limit, though you won't pay tax unless you exceed your much larger $13.99 million lifetime gift/estate tax exemption. The gift is considered yours (the giver) for tax purposes, not your son's.
In California, a gift is legally defined as the transfer of property from one individual to another without receiving anything in return or receiving less than the full value of the property.
Who must file. Generally, any person in a trade or business who receives more than $10,000 in cash in a single transaction or in related transactions must file a Form 8300. By law, a "person" is an individual, company, corporation, partnership, association, trust or estate.
The "20k rule" refers to the traditional IRS threshold for reporting income from payment apps and online marketplaces on Form 1099-K: over $20,000 in gross payments AND more than 200 transactions in a calendar year. While a law (the American Rescue Plan) temporarily lowered the threshold to $600, recent legislation, the One Big Beautiful Bill Act (OBBBA) (OBBBA), has reinstated the $20,000/200-transaction rule for tax years starting in 2025, providing relief for casual sellers and gig workers.
A family loan can have tax implications, but whether it is considered taxable income depends on the nature of the transaction. The IRS generally views a loan as non-taxable if it is a genuine debt with an expectation of repayment.
When parents convert a loan into a gift, many therefore do so with good intentions. However, those that do may often overlook a critical legal requirement that could affect inheritance tax planning. HMRC will not recognise a loan waiver as a gift unless it document by way of a deed.
The IRS presumes that intrafamily transactions are gifts. So, to ensure that a loan is treated as such, you must take steps to demonstrate that you and the borrower have a bona fide creditor-debtor relationship.
If you lend more than $10,000 to a relative, charge at least the applicable federal interest rate (AFR) — and be aware that the interest will be taxable income to you. If you charge no interest or below-AFR interest, taxable interest is calculated under the complicated below-market-rate loan rules.
Three elements must be met for a gift to be legally valid:
Debt collectors must prove three key things: that the debt is yours, that the amount is correct and that they have the right to collect it. If they can't, they're not allowed to continue pursuing you for payment.
