Interest Income
Revenue earned by the association from investing reserve or operating funds in interest-bearing accounts or instruments. Interest income supplements assessment revenue and helps offset the effects of inflation on future replacement costs. Common investment vehicles for HOA funds include FDIC-insured savings accounts, money market accounts, certificates of deposit (CDs), and U.S. Treasury securities. For a community with a $2 million reserve fund earning 4% annually, interest income would generate approximately $80,000 per year — a meaningful contribution that can reduce the assessment burden on homeowners. The interest rate assumption used in the reserve study directly affects the calculated contribution schedule: a higher assumed rate of return lowers required contributions, but overestimating returns creates a funding risk. Boards should use conservative interest rate assumptions that reflect realistic, sustainable yields rather than optimistic projections. HOA investment decisions are governed by the board's fiduciary duty, which prioritizes safety of principal and liquidity over maximizing returns. California Civil Code Section 5510(b)(5) requires the annual budget report to disclose the assumed interest rate used in reserve funding calculations. Boards should adopt a written investment policy that specifies permissible instruments, maximum maturities (typically matching the reserve expenditure schedule), diversification requirements, and the process for selecting financial institutions. Interest income is generally taxable to the association and should be reported on the annual tax return (Form 1120-H for HOAs).
Frequently Asked Questions
Is interest earned on HOA reserve funds taxable?
Yes. Interest and investment income earned by an HOA is generally taxable. Most HOAs file IRS Form 1120-H, which taxes non-exempt function income (including interest) at a flat 30% rate, while exempt function income (assessments used for the maintenance of common areas) is not taxed. Some associations file Form 1120 instead if it results in a lower tax liability. The association should work with its CPA to determine the most advantageous filing approach each year.
