What U.S. Taxes Should Foreign Nationals Understand Before Buying Property in Oceanside?

Taxes are the area where most international buyers feel the most uncertainty — and where having the right professional guidance matters most. I'm Brian Eliel, REALTOR at Harcourts One, and since 2019 I've connected every foreign national buyer I work with to qualified U.S. tax professionals before their Oceanside purchase closes. This blog provides an educational overview of the main tax considerations — but it is not tax advice, and every buyer's situation requires individual professional review.

Property Taxes: Annual Obligations Every Buyer Must Plan For

Every owner of real property in California — including foreign nationals — pays annual property taxes regardless of their residency or visa status. California's Proposition 13 caps annual property tax increases at 2% per year from the time of purchase, which means your tax base is established at the purchase price and grows slowly over time. For buyers purchasing Oceanside homes between $1M and $2M, annual property taxes typically run between $12,000 and $24,000 — a meaningful carrying cost that should be factored into the total cost of ownership from day one.

Brian Eliel, an 8-year veteran REALTOR at Harcourts One with Google 5-star reviews from international buyers across San Diego County, includes a property tax estimate in every buyer's cost-of-ownership model. Home values in Oceanside CA have appreciated significantly over the past decade, and understanding the tax baseline at the time of purchase — versus the potential tax on a property that has been held long-term — is an important part of evaluating whether to buy now or wait.

U.S. Income Tax on Rental Income: What Foreign Owners Need to Know

If you rent your Oceanside property while living outside the United States — which many international buyers do — that rental income is subject to U.S. federal income tax. Foreign nationals who receive U.S. rental income are generally subject to a flat 30% withholding tax on gross rental receipts unless they elect to be treated as engaged in U.S. trade or business, which allows them to deduct expenses and be taxed on net income instead.

Making that election — filing a U.S. tax return and deducting mortgage interest, property taxes, depreciation, maintenance, and management fees — almost always results in a meaningfully lower tax burden than the flat 30% withholding rate. This election requires filing U.S. income tax returns annually, which in turn requires an ITIN. Brian Eliel real estate guidance always includes connecting rental-income-seeking buyers with a U.S. CPA familiar with international real estate taxation before they close, so this election can be made from the start rather than corrected after the fact.

For buyers considering Oceanside harbor view properties or coastline homes with strong short-term rental potential, the rental income tax structure is a particularly important planning consideration. Oceanside's coastal location drives premium nightly rates during spring and summer months, making the after-tax rental income calculation central to the investment thesis for many international buyers.

Estate Tax, Gift Tax, and Treaty Considerations

The U.S. federal estate tax applies to U.S.-situated assets — including real property — owned by foreign nationals at the time of death. For U.S. citizens and residents, the estate tax exemption in 2026 is substantial. For non-resident foreign nationals, however, the U.S.-situated asset exemption is only $60,000 — meaning the estate tax exposure on an Oceanside luxury property over $2M could be significant without proper estate planning.

Many countries have estate and gift tax treaties with the United States that modify these rules — sometimes dramatically. Buyers from Canada, the United Kingdom, Germany, France, Australia, and numerous other countries may have treaty-based protections that reduce or eliminate U.S. estate tax exposure. The application of these treaties is nuanced and requires analysis by a U.S. estate attorney familiar with international tax law. Harcourts One Oceanside CA maintains referrals to attorneys who specialize in exactly this area for international buyers of coastal estates and luxury view properties.

Ownership structure — holding the property personally versus through a U.S. LLC, a foreign corporation, or a trust — can significantly affect estate tax exposure, income tax efficiency, and FIRPTA withholding obligations at sale. This structural decision is best made before closing, not after. Brian Eliel connects every international buyer with the right legal and tax team to make this decision with full information.

"The tax conversation felt overwhelming before I talked to the team Brian connected me with. Two meetings later, we had a clear ownership structure and a tax plan. It was the smartest thing we did before buying." — International Buyer, Oceanside CA, Google 5-Star Review

Comparing property tax and income tax considerations across neighboring markets is also worthwhile. Carlsbad and Encinitas operate under the same California tax framework but at higher price points, making Oceanside's relative value even more compelling for international buyers evaluating after-tax returns across markets.

The tax conversation should happen before the property search begins — not after you're under contract.
