How tax applies to a boat purchase
The rate depends on where the boat is registered or kept. Financing the tax adds it to the balance and attracts interest for the whole term; paying it upfront keeps the loan smaller.
On larger boats the tax can be a five-figure sum, so the choice between paying and financing it matters more than on a car.
Worked example
A £60,000 boat at 7.5% tax carries £4,500 of tax, so the price including tax is £64,500. With a £12,000 deposit and the tax financed, £52,500 is borrowed.
At 8.5% over 10 years the payment is £650.92, the interest is £25,610.98 and the total cost including the deposit is £90,110.98.
Check the local rules
Marine tax rules vary: some places charge VAT, some charge sales tax, and some treat a boat kept abroad differently. Use the rate on your paperwork.
If the sale is exempt or treated as a business purchase, enter 0 and keep the evidence.

CALCULATOR QUESTIONS
Boat loan calculator with sales tax questions
How much tax is charged on a £60,000 boat at 7.5%?
£4,500, making the price including tax £64,500.
Should I finance the tax?
Only if paying it upfront would stretch your cash. Financing adds interest over the whole term.
Is VAT different from sales tax?
The arithmetic is the same, but the rules on what is taxable and where differ. Check the invoice.
Does a trade-in reduce the tax?
In some places. This calculator applies the rate to the full price, so adjust the price if your jurisdiction deducts a trade-in.
