Malta’s Tonnage Tax: How Shipping Companies Are Taxed on Tonnage, Not Profit

Most companies pay tax on what they earn. A shipping company in Malta can choose to pay tax on how big its ships are instead.

That sounds odd until you have run a shipping business through a bad year. Freight rates swing. A route that paid well in spring can lose money by autumn. Ordinary corporate tax follows the profit. So the tax bill moves with the market, and you only know it once the year is over.

Malta’s tonnage tax regime does the opposite. It sets the tax by the ship’s net tonnage. That is a measure of usable capacity, not weight. The figure is known at the start of the year, and it does not move with your profit.

This article explains who can use it, what it replaces, and what it asks in return.

Who this is for

Tonnage tax is a shipping regime. It is built for merchant vessels: cargo ships, tankers, bulk carriers, container ships, and passenger and cruise ships.

It is worth being clear about what it is not for. Private and commercial yachts do not belong here. Yacht owners face a different set of rules, built around VAT leasing and the Fiscal Unit. If that is the question, our yacht content covers it.

What the regime does

The mechanism sits in the Merchant Shipping Act and the regulations interposed under it.

A vessel has to be owned or operated through a licensed Maltese shipping organisation. That is the starting point, not the whole test. The ship itself has to qualify. So does the activity it performs, and so does the income it earns. Where all of that holds, the organisation can elect into the regime. The election then takes its qualifying shipping activities out of corporate income tax.

In place of tax on profit, the company pays one annual amount, calculated from the ship’s net tonnage. Qualifying shipping income is exempt from income tax, and gains on a qualifying disposal of the vessel are exempt as well.

The word “shipping” is doing real work in those sentences. The exemption covers shipping activities. Income from something else the company happens to do is taxed normally.

Why certainty is the point

Set the two systems next to each other and the gain is not only a smaller bill. It is knowing the number.

Take a company operating one vessel. Under ordinary corporate tax, a strong year brings a large tax bill. A weak year brings a small one. Neither figure is known until the accounts are closed. Under tonnage tax the amount does not follow the profit at all, and it was known in January.

That changes how a business can be run. Charter rates can be quoted against a fixed cost base. Lenders can see the tax line for the life of a loan. A shipowner deciding whether to take a vessel on can price the tax without guessing at the freight market.

The stronger the operation, the wider the gap grows. A company that trades a vessel hard all year pays the same tonnage figure as one that trades it lightly.

The honest caveats

Three conditions deserve attention before anyone treats this as free money.

It is payable whether or not you make a profit. This is the real trade. In a year with no revenue, the tonnage tax is still due. A company that plans to operate a vessel occasionally should model both systems properly rather than assuming the election wins.

Shipping income has to be kept separate. The regime requires the organisation to account for shipping income apart from any other activity. Mixed accounts are how an election gets challenged.

The structure has to be right first. The election depends on a licensed shipping organisation holding or operating the vessel. Get the corporate vehicle wrong and the election is not available. Fixing it later is slower and dearer than building it correctly.

What Malta brings around the tax

The tax regime is one reason companies register in Malta. It is not the only one, and on its own it would not explain the scale.

Malta’s main register passed 10,000 vessels in early 2025. By November 2025 the fleet stood at roughly 89 million gross tonnes, up about 3% on the year. That makes Malta the largest register in the European Union, and sixth largest in the world.

Reputation follows. In the International Chamber of Shipping’s 2025 to 2026 performance table, Malta scored green on all nineteen criteria. It also holds White List status on both the Paris and Tokyo port state control agreements. Flag performance feeds into how port authorities choose which ships to inspect. A well-regarded flag tends to help. No flag guarantees an easy time for any one ship.

The administration is built for use. Provisional registration can be completed in 48 hours where the paperwork is in order. The registry runs around the clock. Electronic certificates with QR checks have been issued since June 2025.

The 2025 changes worth knowing

Malta amended the Merchant Shipping Act in February 2025, with the changes in force from around 16 April. Several matter to owners and financiers.

Malta became the first country in the European Union to offer a Finance Charter Instrument. It lets a financier register its interest in a lease directly against the vessel. That makes lease financing cleaner to secure.

Mortgages over ships still under construction can now be registered for three years rather than two. Malta also recognises mortgages registered in certain other jurisdictions, which helps cross-border lending, though recognition still depends on the jurisdiction involved. Seafarers’ wage claims now run for twelve months instead of three. That brings Malta in line with the Maritime Labour Convention.

One change tightens things. The age limit for ships entering the register dropped from 25 years to 20. That is a condition of getting on the register, not of the tax regime. But it decides whether the tonnage tax question arises at all.

Emissions are now part of the calculation

Since 1 May 2025 the Mediterranean has been a Sulphur Emission Control Area. The limit on sulphur in fuel fell from 0.50% to 0.10%. That should cut sulphur emissions in the region by around 80%.

Compliance costs money, either through cleaner fuel or through exhaust cleaning kit. Malta’s response was to reward the cleaner end of the fleet. Lower-emission vessels get reduced registration fees and tonnage tax incentives. Check the criteria and the size of the reduction against the current schedule. Do that before either goes into a business case.

For an owner planning a newbuild or a re-engine, that is worth modelling. The emissions decision and the tax decision are no longer separate.

How Zenco Partners can help

We set up and run Maltese shipping organisations. We handle the tonnage tax election, and keep the accounting the regime requires. We also advise on the ownership structure above the vessel. Where a group has activities beyond shipping, we cover the corporate tax position too.

Where an election is not the right answer, we will say so and model the alternative.
