Luxury Real Estate, Yachting, and Offshore Taxation

1. Typical Property Taxes on Beachfront Homes

Property taxes vary wildly depending on the jurisdiction, local assessment rules, and whether the buyer is a resident or foreign national. For a luxury, new beachfront home, here is what you can expect in prime markets:

Nantucket, Massachusetts: Ironically, Nantucket has one of the lowest property tax rates in Massachusetts, typically around 0.31% to 0.36% (or $3.18 to $3.60 per $1,000 of assessed value). However, because beachfront homes often cost $10M–$30M+, the absolute tax bill is substantial. Additionally, buyers must pay a one-time 2% Land Bank Fee on the purchase price.
Malibu, California: Thanks to Proposition 13, property taxes are assessed at approximately 1.1% to 1.25% of the purchase price. For a new beachfront build, the tax basis will be the cost of the land plus the cost of construction. Deductions are minimal, but the assessment cannot rise more than 2% per year until the property is sold again.
Palm Beach, Florida: The total millage rate equates to roughly 1.1% to 1.2% of the assessed value annually. Florida has no state income tax, making it popular for wealthy buyers, but property taxes on a $20M mega-mansion can easily exceed $200,000 a year.
Bermuda: Taxation here is entirely different. Bermuda assesses an Annual Rental Value (ARV) for properties. The land tax is fiercely progressive; for high-end luxury homes (the highest ARV tier), the annual tax rate can be up to 47% of the ARV. Furthermore, non-Bermudian buyers must obtain an Alien License, which usually costs a massive 8% to 12.5% of the property's purchase price upfront.
Other Locations (e.g., The Bahamas): Non-Bahamians buying high-end beachfront property (over $500k) pay an annual property tax of up to 1% to 1.5%. There is also a substantial VAT/Stamp Tax on the initial purchase—often 10% to 12% of the value.

2. Typical Taxes for Yacht Owners

Owning a yacht comes with a multitude of tax obligations beyond the purchase price. Typical taxes include:

Sales or Value-Added Tax (VAT): Paid at the time of purchase. In the US, state sales taxes range from 0% (Rhode Island) to 6-8% depending on the state of registration. In Europe, VAT is much higher (typically 20-22%) depending on the EU country where the yacht is imported or delivered.
Use Tax: If you buy a yacht in a tax-free jurisdiction and bring it into a taxed jurisdiction (like California or Florida) and keep it there beyond a grace period (e.g., 90 days), the local state will assess a "Use Tax" equivalent to their sales tax.
Annual Personal Property Tax: Some US states and counties assess an annual property tax on boats (e.g., California assesses roughly 1% of the vessel's value annually).
Registration & Tonnage Taxes: Annual fees paid to the flag state (e.g., Marshall Islands, Cayman Islands, or US Coast Guard).

3. Having a Yacht as a Legal Residence

Attempting to use a yacht as your sole legal residence causes several severe administrative and legal challenges in most countries:

The "Know Your Customer" (KYC) Problem: Following modern anti-money laundering (AML) laws, almost all global banks, brokerages, and insurance companies require a physical, terrestrial residential address. A marina berth, PO Box, or mail-forwarding service will frequently be rejected by financial institutions.

Tax Domicile: Tax authorities (like the IRS or HMRC) don't allow you to be a "resident of nowhere." If you sever physical ties with a country to live on a yacht, but do not establish a legal tax residency in a new country, your home country will often claim you are still domiciled there and tax you globally.
Zoning/Liveaboard Laws: Most first-world marinas and local municipalities strictly limit the number of "liveaboard" vessels. You usually cannot legally inhabit a boat 365 days a year in a single marina without special, hard-to-acquire liveaboard status.

4. Taxes Paid During a Yacht Circumnavigation

A family undertaking a circumnavigation doesn't exactly pay "international transit taxes," but they will trigger a cascade of localized fees and import rules:

Cruising Permits & Transit Logs: Most countries require you to purchase a cruising permit to navigate their waters.
Visas & Immigration Fees: Port agents and customs officials will charge entry/clearance fees, and occasionally departure taxes per crew member.
Canal Fees: Transiting the Panama or Suez Canals requires massive toll fees (often $1,500 to $3,000+ for standard cruising yachts depending on length).
Temporary Importation (The VAT Trap): This is the biggest tax risk. Most countries allow a yacht to stay for a limited time under "Temporary Admission" (e.g., 18 months in the EU, or 12 months in Australia). If you exceed this time limit without leaving the territory's waters, the yacht legally becomes an "import," and the owner is hit with a massive VAT or import duty bill (10% to 22% of the yacht's current value).

5. Seasteading in International Waters (Panama Flag) & Income Tax

If you live on a seastead registered in Panama, parked in international waters, how you are taxed relates to the laws of your citizenship. Assuming by "5 richest countries" we are looking at standard major global economies (USA, China, Germany, Japan, UK):

United States: The US uses citizenship-based taxation. It does not matter if you live on the moon or a Panamanian seastead; you must file and pay US income tax on your global income. You might qualify for the Foreign Earned Income Exclusion (FEIE), but only if you can prove your tax home is in a foreign country (very difficult to prove if you are in international waters, which the IRS does not consider a foreign country).
United Kingdom, Germany, Japan, China: These countries use residence-based taxation. In theory, if you permanently leave and establish your life outside their borders, you stop paying their income tax. However, there is a catch: The Exit / Domicile Trap.

To break tax residency in countries like Germany or the UK, you generally have to prove you have established a permanent, tax-liable home elsewhere. Floating outside national borders does not automatically establish a new domicile. If you don't officially belong to the tax system of Panama (or another nation), your home country will likely argue that your "center of vital interests" remains with them, continuing to tax your global income. Additionally, countries like Germany impose heavy "Exit Taxes" on wealth and unrealized gains when you leave.

6. Corporate Ownership of Yachts to Avoid Sales Tax

You mentioned registering a yacht to a corporation (like an LLC) so that instead of selling the boat (which triggers sales tax), you sell the corporation. There is no sales tax on transferring company shares.

How common is this? It is extremely common in the luxury yacht world, but the legal loopholes are actively closing.

Historically, buyers would form a Delaware LLC, a BVI (British Virgin Islands), or a Cayman Islands holding company solely to own the vessel. When it was time to sell, the buyer simply bought the LLC.
