Are Lombard Loan Interest Payments Tax Deductible in 2026?

Sometimes yes on a Lombard loan, interest is deductible only for deductible investment or business use; personal spending is generally not deductible in 2026. See if you qualify.

The specifics

For high-net-worth personal loans and private wealth credit lines, the tax question is not whether the loan is secured by a portfolio. It is whether the borrowed money was spent on a deductible purpose. Under IRS Topic 505, personal interest is generally not deductible, and investment interest is deductible only to the extent of net investment income. The tracing rule matters more than the label on the facility: 26 CFR 1.163-8T allocates interest expense by what the loan proceeds actually paid for. So if a Lombard loan funds taxable investments, the interest may fit the investment-interest rules; if it funds household spending, tuition, travel, or other personal cash flow, the deduction usually fails. If you are using tax-efficient borrowing strategies, the clean result comes from clean tracing and clean records. That is the standard reflected in our methodology, where the claim has to stand on the tax rule, not on the product name. Private banks describe these facilities as securities-backed or investment-backed lending, including J.P. Morgan Private Bank, RBC Wealth Management, and BNP Paribas Wealth Management.

Qualification & edge cases

Edge cases turn on mixed use, refinancing, and what the proceeds actually paid for. If one draw covers both personal spending and an investment purchase, only the allocable investment portion may qualify under the tracing rules in 26 CFR 1.163-8T. If the funds are used for tax-exempt investments or other nondeductible uses, the deduction can be reduced or lost under the general interest rules summarized by the IRS and Cornell's version of Section 163. Collateral alone does not change the outcome: pledging a securities portfolio makes the loan a Lombard or investment-backed facility, but it does not make every dollar of interest deductible. For owners using credit for a sale transition, estate liquidity, or a succession event, the same rule applies; the tax answer follows the use of proceeds, which is why a strategic credit exit plan only works when the tax treatment is mapped first. If you are on the margin, separate business, investment, and personal draws, and keep the sub-accounts and statements clean so the deduction can be traced.

Background & how it works

A Lombard loan is a form of asset-based lending for high earners: a private bank or wealth manager lends against eligible securities instead of forcing a sale. Providers such as J.P. Morgan Private Bank, RBC Wealth Management, BNP Paribas Wealth Management, and HSBC Private Bank describe these products as tailored lending or investment-backed credit lines. That is why they show up in conversations about [private wealth credit lines] and [wealth management financing options]: the borrower can keep assets invested while unlocking liquidity for taxes, acquisitions, or other capital needs. The tradeoff is market risk. If the pledged portfolio falls, the lender can ask for more collateral or repayment. That risk is separate from tax treatment, though. For 2026, the IRS rule stays the same: the collateral secures the loan, but the borrower's use of proceeds controls whether the interest is deductible.

Bottom line

A Lombard loan does not automatically create a tax deduction. In 2026, the deduction depends on what the money actually paid for, and personal use usually means no deduction. If you want the answer to hold up, see if you qualify before you draw.
