Key Takeaways
- Stamp duty applies to a range of documents and transactions in Antigua and Barbuda, including property transfers, share dealings, leases, mortgages and gifts.
- Foreign investors should note that property transfers can attract duty on both the vendor and the purchaser, calculated against consideration or assessed value.
- Exemptions, reliefs and development concessions may reduce or remove liability, so eligibility is worth checking before a transaction completes.
- Meeting stamping deadlines matters, as late stamping can trigger penalties for companies and individuals alike.
Understanding Stamp Duty in Antigua and Barbuda
Stamp duty in Antigua and Barbuda, sometimes called stamp tax, is a transaction tax charged on written instruments such as bills of sale, leases, mortgages, contracts, and bills of lading. The country levies no personal income tax, no capital gains tax, and no inheritance tax, so indirect charges of this kind carry real fiscal weight. Stamp duty is actively imposed and administered by the Inland Revenue Department, not a dormant levy you can disregard.
For property transfers, both sides of the deal pay. The duty is calculated on the consideration stated in the sale or the assessed value of the property, whichever figure is higher.
This article explains who pays, the rates that apply, how the charge is calculated, the exemptions that exist, and the deadlines and penalties attached to stamping. It is written for foreign buyers, investors, and the advisers structuring their entry into the market.
The Legal Basis: The Stamp Act (Cap. 410) and the Inland Revenue Department
The governing statute is the Stamp Act, Cap. 410, first enacted on 31 December 1887 and amended several times since, with recorded amendment ordinances through the 1980s and 1990s. The text is published on the official laws portal, and its long colonial pedigree means the drafting is detailed but dated in places.
The Act defines an "instrument" as every written document, and assigns collection and stamping duties to the Commissioner of Inland Revenue. Cabinet may make subsidiary orders under Sections 4 and 5, which is how rates and details are adjusted without amending the primary law.
Administration sits with the Inland Revenue Department, a unit within the Ministry of Finance and Corporate Governance led by the Commissioner. The IRD also administers the broader Tax Administration and Procedures Act No. 12 of 2018, which governs collection and procedure across the tax system.
An instrument that should be stamped but is not cannot be admitted as evidence in court proceedings. Skipping the duty does not just risk a penalty; it can leave your contract or transfer unenforceable.

Which Documents and Transactions Are Dutiable
The Act reaches a broad set of written instruments. The most common dutiable documents for a foreign-owned business include the following.
- Conveyances on sale of freehold or leasehold property
- Leases and mortgages
- Bills of sale, contracts, and agreements
- Bills of lading and charterparties
- Promissory notes, bills of exchange, cheques, bonds, and debentures
- Marketable securities capable of being bought and sold on a stock market
A "conveyance on sale" is defined widely under section 53 to capture any instrument, decree, or court order by which property is transferred to a purchaser on a sale. Transfers occurring on an occasion other than a sale or mortgage are still chargeable as conveyances under section 61.
Voluntary gifts during a person's lifetime are not exempt. A gift inter vivos is taxed as if it were a sale, with the value of the property standing in for the purchase consideration.
Stamp Duty on Property Transfers: Vendor and Purchaser Rates
Real estate is where stamp duty bites hardest, and both parties contribute. The rates are fixed by law and cannot be negotiated between buyer and seller.
| Party | Rate | Base |
|---|---|---|
| Vendor (seller) | 7.5% | Higher of consideration or assessed value |
| Purchaser (buyer) | 2.5% | Higher of consideration or assessed value |
Duty is settled at closing, when the transfer instrument is executed and stamped. There are no documented first-time buyer reliefs or reduced rates, and no difference between a new-build and a resale, so budget for the full 2.5% buyer charge in every case.
Two further costs sit alongside the duty for non-residents and must not be confused with it. A seller without local tax residence pays a separate Appreciation Tax of 5% on the assessed value, and a non-citizen purchaser pays an additional 5% Non-Citizen Landholding Licence fee.
The 5% Appreciation Tax and the 5% Non-Citizen Landholding Licence fee are distinct levies charged on top of the 2.5% buyer duty. A foreign buyer should plan for the full combined cost when modelling a purchase.

Stamp Duty on Share and Marketable Security Transfers
Transfers of shares and marketable securities are dutiable, and both buyer and seller are charged. The base is the higher of the market value or the book value of the shares.
The charge is ad valorem, meaning it scales with value rather than being a flat fee. The specific percentage for share transfers sits in the Schedule to the Act, which is not reproduced in the publicly retrievable text fragments, so confirm the applicable rate with the Inland Revenue Department before executing a transfer.
Stamp Duty on Leases, Mortgages, Gifts and Other Instruments
Beyond outright sales, several routine business instruments attract duty. Each is chargeable under the Schedule to the Act, with rates that vary by instrument type.
Mortgages, charges, liens, and other incumbrances over freehold or leasehold property must be stamped under section 30. Leases are listed as dutiable, though the exact schedule figure is not retrievable from the public text and should be verified with the IRD.
Gifts deserve particular attention. A voluntary lifetime transfer is treated like a sale, so the same duty applies, calculated on the property's value rather than any price paid.
Some relief exists for qualifying small business borrowing. The Small Business Development Act 2007 (No. 24 of 2007) references stamp duty exemptions under Cap. 410 headings covering certain bills of exchange, bonds, and mortgage instruments tied to qualifying loans.
Charterparties carry their own timing rules. An unstamped charterparty may be stamped within three days of first execution on payment of a EC$50 penalty, or after three days but within one month on payment of EC$250, after which the Commissioner cannot stamp it.

How Stamp Duty Is Calculated: Consideration vs. Assessed Value
The calculation rests on a simple comparison: duty is charged on the consideration stated in the instrument or the assessed value of the asset, whichever is higher. This prevents under-declaration of price to reduce the charge.
For real estate, the assessed value reflects the market value at the time of purchase and is determined by an authorised valuer engaged when the property is prepared for sale. For shares, the comparison runs between market value and book value.
The Act addresses more complex structures too. Where a property is conveyed in consideration of a debt owed to the buyer, or subject to payment of money or stock, that amount is treated as part of the consideration for ad valorem purposes.
Split transactions are handled under section 57. When property sold for a single price is conveyed in parts through different instruments, the parties may apportion the consideration as they choose, and each instrument is charged on its own apportioned share.
Exemptions, Reliefs and Development Concessions
Genuine reliefs from stamp duty are narrow, and a foreign buyer should not assume one applies. There is no first-time buyer relief and no reduced rate for newcomers to the market.
The clearest concession concerns citizenship by investment. Foreign investors who acquire citizenship through that programme are not required to pay the Non-Citizen Landholding Licence fee on property bought through it, removing one of the two 5% add-ons.
Broader incentives exist for development projects. The Investment Incentive Programme can grant tax holidays, duty exemptions, and customs concessions for qualifying investments, assessed case by case rather than as an automatic entitlement.
A practical relief applies to documents signed abroad. An instrument first executed outside the country may be stamped within two months of its first receipt locally on payment of the unpaid duty alone, with no penalty.
An International Business Company benefits from a 50-year exemption framed around corporate and income taxes. Whether that exemption extends to stamp duty on instruments the IBC executes is not confirmed in the governing texts, so seek written guidance before relying on it.
How and When to Pay: Stamping, Deadlines and Penalties for Late Stamping
For a property purchase, duty falls due at closing, when the transfer is executed and presented for stamping through the Commissioner of Inland Revenue. Leaving an instrument unstamped does not just expose you to a penalty; it strips the document of evidential value in court.
The penalty regime escalates with delay. The default rule and the instrument-specific timelines work as follows.
| Situation | Window | Penalty |
|---|---|---|
| Charterparty, after execution | Within 3 days | EC$50 |
| Charterparty, after execution | 3 days to 1 month | EC$250 |
| General default, unstamped instrument | After execution | EC$500 plus 8% annual interest on unpaid duty over EC$50 |
| Instrument executed abroad | Within 2 months of local receipt | Unpaid duty only, no penalty |
Interest on the general default accrues from the date of first execution and runs until it equals the unpaid duty amount. Beyond the charterparty window, the Commissioner loses the authority to stamp the document at all.
Payment can be made through several channels operated by the Inland Revenue Department, including ACB online, ECAB MORE Banking, and FCIB online, as well as by wire transfer. The IRD runs a dedicated stamp duties function to handle assessment and stamping.
Stamp Duty Considerations for Companies and Foreign Investors
Property may be held by an individual or a company, but the corporate route does not sidestep the non-citizen rules. A company controlled by non-citizens, or one registered abroad, is itself treated as a non-citizen for landholding purposes.
That status carries consequences. Buying through a non-citizen-controlled company can still trigger the Non-Citizen Landholding Licence requirement, and failure to obtain that licence can render the sale void at the government's discretion.
International Business Companies sit in a different position. Foreigners may own all the shares in an IBC, and the structure enjoys a 50-year exemption covering most income, but IBCs cannot own real estate locally or trade within the country.
The wider compliance picture has improved for foreign investors. The Council of the European Union removed the country from its list of non-cooperative tax jurisdictions in October 2024, and a network of Tax Information Exchange Agreements is in place with partners including Canada, Germany, the United Kingdom, and the United States.
Where an investor acquires property as a resident, the 2.5% buyer duty matches what a citizen pays. The 5% Non-Citizen Landholding Licence fee is the defining extra cost for those who remain non-citizens.
Conclusion
Stamp duty in Antigua and Barbuda sits on both sides of a property deal, and that bilateral structure is the single detail a foreign business owner most often underestimates when modelling transaction costs. Before any instrument is signed, the practical question is not whether duty applies but whether a concession or exemption already exists that could lawfully reduce the bill.
Checking exemption eligibility before a transaction closes, not after, is where the real decision sits.

Frequently Asked Questions
Both parties pay. The seller is charged 7.5% and the buyer 2.5%, each calculated on the higher of the sale consideration or the assessed value, and these rates are fixed by law and not open to negotiation.
The 2.5% buyer duty is the same for citizens and non-citizens. The added cost for a non-citizen is the separate 5% Non-Citizen Landholding Licence fee, and a non-resident seller faces a separate 5% Appreciation Tax, both of which sit outside stamp duty itself.
Late stamping triggers penalties that escalate with delay, and the general default rule adds a EC$500 penalty plus 8% annual interest on unpaid duty above EC$50, running from the date of execution. An unstamped instrument that should have been stamped is also inadmissible as evidence in court.
Yes. A voluntary lifetime gift is charged the same duty as a conveyance on sale under section 62 of the Stamp Act, with the property's value used in place of a purchase price.
An International Business Company holds a 50-year exemption framed around corporate and income taxes, but the texts do not confirm that this covers stamp duty on instruments the company executes. Because IBCs also cannot own local real estate, you should obtain written confirmation before assuming any stamp duty relief applies.
To an extent. An instrument first executed abroad may be stamped within two months of its first receipt locally on payment of the unpaid duty only, with no penalty applied if you act within that window.
