Can I Use a 401(k) Loan for a Down Payment?

A 401(k) loan offers a way to access funds from your retirement savings, potentially for a down payment on a home. This option allows you to borrow directly from your own vested account balance, rather than from a traditional lender. Unlike a withdrawal, a 401(k) loan is not considered a taxable distribution, provided it is repaid according to the established terms.

General Rules for 401(k) Loans

Not all 401(k) plans offer a loan feature, as plan sponsors have the discretion to include or exclude this option. If available, eligibility typically extends to active employees who have a vested balance in their account. You can determine if your plan permits loans by reviewing your plan’s summary plan description or contacting your plan administrator.

The Internal Revenue Service (IRS) sets specific limits on the maximum amount that can be borrowed from a 401(k) plan. Generally, the loan amount cannot exceed the lesser of $50,000 or 50% of your vested account balance. There is an exception: if 50% of the vested account balance is less than $10,000, you may be able to borrow up to $10,000, though plans are not obligated to offer this specific exception. For instance, if your vested balance is $80,000, the maximum loan amount would be $40,000. However, if your vested balance is $120,000, the maximum loan remains $50,000.

Most general-purpose 401(k) loans must be repaid within five years. However, a significant exception applies when the loan is used for the purchase of a primary residence. In such cases, the repayment period can be significantly longer, potentially extending up to 10, 15, or even 30 years, depending on the specific terms allowed by the plan. Repayments must be made in substantially equal payments that include both principal and interest, occurring at least quarterly.

Interest is charged on 401(k) loans, and the rate is typically set by the plan administrator, often at the prime rate plus one or two percentage points. A distinguishing characteristic of these loans is that the interest you pay is returned to your own 401(k) account. This means that while you pay interest, it effectively goes back into your retirement savings, making it a transfer from one of your pockets to another, rather than an expense paid to an external lender. Some plans may also require spousal consent for loans exceeding a certain amount, such as $5,000.

Applying for a 401(k) Loan

Begin by reviewing your employer’s plan documents or contacting your plan administrator or human resources department. This will provide specific details on how to initiate a loan request, including any unique requirements or forms. Plan administrators often provide online portals or specific forms for this purpose.

The application typically requires information such as the desired loan amount and the proposed repayment schedule. Some plans may also ask for a general reason for the loan, especially if you are requesting a longer repayment term for a primary residence purchase. There is usually no credit check involved, as you are borrowing from your own funds, and taking a 401(k) loan does not affect your credit score.

After submitting your application, it undergoes a review process. This initial review can often be completed within one business day. If additional documentation is required, particularly for a primary residence loan, the review time may extend, potentially taking five to seven business days or more. Upon approval, you will typically receive a promissory note, often electronically, which outlines the terms and conditions of the loan.

Once the promissory note is signed, the loan processing usually takes around seven business days. Funds are then disbursed, commonly via direct deposit to your bank account or through a check. Direct deposits typically clear within two to three business days, while checks may take seven to ten business days to arrive by mail. The repayment period typically begins shortly after you receive the funds, with payments often set up as automatic payroll deductions.

Financial Implications of a 401(k) Loan

Repayment of the loan is usually facilitated through automatic deductions from your paycheck. These deductions include both principal and interest payments, ensuring a consistent repayment schedule.

A significant consideration is the impact on your investment growth. When you take a loan, the corresponding amount is temporarily removed from your invested portfolio. This means the borrowed funds are not participating in market gains or compounding returns during the loan’s repayment period. While the interest you pay back mitigates some of this loss, it may not fully offset the potential growth that could have been achieved had the funds remained invested. The opportunity cost, or the lost potential earnings, represents a real financial consequence.

Failing to repay a 401(k) loan has consequences. If you default on the loan, the outstanding balance is generally treated as a taxable distribution from your retirement plan. This means the defaulted amount becomes subject to income tax for the year in which the default occurs. Furthermore, if you are under the age of 59½ at the time of default, the outstanding balance may also incur an additional 10% early withdrawal penalty.

Job termination can also trigger immediate repayment obligations. Many plans require the full outstanding loan balance to be repaid if your employment ends, whether voluntarily or involuntarily. If you are unable to repay the loan by the specified deadline, typically the due date of your federal income tax return for that year (including extensions), it will be considered a taxable distribution subject to the same income tax and potential 10% early withdrawal penalty. The tax implications can be considerable.
