Key Takeaways
- Antigua and Barbuda has no standalone payroll tax; employer obligations run through Social Security and Medical Benefits Scheme contributions instead.
- Foreign-owned employers must register with the Social Security Board and the MBS, then calculate contributions on insurable earnings up to a monthly ceiling.
- Contribution rates differ between public and private sector workers, with age-based adjustments applying to Medical Benefits payments.
- Filing involves the R5A form and set deadlines, and missed or incorrect remittances can trigger surcharges and penalties for hiring companies.
Understanding Payroll Tax in Antigua and Barbuda: Social Security and the Medical Benefits Scheme
Payroll tax in Antigua and Barbuda is not a single levy under one statute. The term describes a set of mandatory contributions an employer must withhold and pay on behalf of staff: contributions to the Social Security Scheme, the Medical Benefits Scheme (MBS), and the Education Levy. Because personal income tax was abolished in 2016, no PAYE deduction applies to resident employees, and the social schemes form the core of an employer's payroll obligations.
The Antigua and Barbuda Social Security Board, which began operations on 2 April 1973, administers contributions that fund pensions, sickness benefits, maternity leave, and work injury cover. You can confirm rates and filing rules directly through the Social Security Board.
This guide explains how those contributions are calculated, who must register, how and when to remit, and what penalties apply for getting it wrong. It is written for foreign owners, investors, and their advisers weighing the cost of employing staff in the country.
The Legal Basis: Why There Is No Standalone Payroll Tax (and the Abolition of PAYE in 2016)
In April 2016 the government set the income tax rate for employees to zero, ending the personal income (payroll) tax that previously applied. The reform was framed as a measure to raise take-home pay and encourage economic activity.
The result is a system built on indirect taxation rather than payroll deduction. Resident employees pay no income tax, and there is no wealth, inheritance, or capital gains tax to consider when structuring compensation.
What remains is the contribution framework. Social security is governed by the Social Security Act, Cap. 408 of 1972, while the MBS sits under the Medical Benefits Regulations, 2011. The Inland Revenue Department administers general tax law under the Tax Administration and Procedures Act of 2018.
Rate adjustments do not require fresh primary legislation. Instead they are enacted by statutory instrument, with the phased contribution increases flowing from Statutory Instrument 2016 No. 60.
The absence of income tax does not relieve you of payroll obligations. Every employer remains liable for social security, MBS, and Education Levy contributions on staff wages.

Social Security Contributions: Private vs. Public Sector Rates
Social security contribution rates differ by sector, and applying the wrong one is a common filing error. Private-sector employers face a higher combined rate than public-sector bodies.
For a private-sector business, the total is 16% of insurable earnings, split between the employer and the worker. The public-sector total is 15%, and self-employed persons contribute 10% on their own account.
| Category | Total | Employer | Employee |
|---|---|---|---|
| Private sector | 16% | 9.5% | 6.5% |
| Public sector | 15% | 9% | 6% |
| Self-employed | 10% | — | — |
These figures sit at the top of a phased schedule. The combined private rate stood at 14% in 2021, rose to 15.5% effective 1 January 2024, and reached 16% effective 1 January 2025. Each step reflects a 0.5% annual increase recommended by the 10th and 11th Actuarial Reviews of 2014.
For a foreign-owned company, the practical figure to budget is the employer share: 9.5% of insurable earnings in the private sector.
Medical Benefits Scheme (MBS) Contributions and Age-Based Adjustments
The MBS funds public healthcare and runs alongside social security as a separate deduction. Employers contribute 3.5% of a worker's gross earnings, with the employee matching that 3.5%, for a combined 7%.
A reduced rate applies to older staff. Workers aged 60 to 69 contribute 2.5% each from employer and employee, rather than the standard 3.5%.
One feature sets the MBS apart from social security. There is no ceiling on gross earnings for MBS purposes, so the 3.5% employer charge continues to apply to the full salary of a high earner, even on the portion above the social security cap.
A senior employee earning well above the social security ceiling still attracts MBS contributions on every dollar of gross pay. Factor this into the cost of hiring management-level staff.

The Contribution Base: Insurable Earnings, What Counts, and the Monthly Ceiling
Social security contributions apply only up to a fixed ceiling on insurable earnings. The maximum is EC$78,000 per year, equivalent to EC$6,500 monthly, EC$3,000 per fortnight, or EC$1,500 per week.
The base is broader than basic salary. Contributions are due on overtime, vacation pay, cost-of-living and housing allowances, shift and holiday pay, bonuses, commissions, service charges, and danger or dirt money.
Several payments fall outside the base:
- Maternity benefits
- Severance packages
- Travelling allowances
- Sick leave benefits
Probationary staff are not exempt. Deductions must begin from the first wages paid, including during any trial period.
Where someone works for two employers at once, each firm pays social security on the wages it pays, each up to the EC$6,500 monthly ceiling. The cap is applied per employer, not pooled across them.
Registering as an Employer with the Social Security Board and the MBS
Registration is time-sensitive. You must register as an employer within seven days of hiring your first worker, and late registration draws penalties calculated from the date that employee actually started, not the date you eventually file.
Three registration numbers are needed in total: one each for social security, MBS, and Education Levy remittance. Employer registration with the Social Security Board requires a business licence, articles of incorporation (or sole trader registration), and a completed Form SS-1. The Board then issues an employer registration number that must appear on every contribution filing.
Each new hire is registered separately. You submit Form SS-2 for every employee, and the Board issues a social security number to anyone who does not already hold one.
Foreign nationals on your payroll need additional documents. They must provide their home passport together with a verified work permit from your business as the registering employer.
The MBS requires its own registration, obtained separately from the social security process. Online employer registration is available through the Social Security Board website.

Remittance and Reporting: The R5A Form, Deadlines, and Self-Employed Obligations
Contributions are reported and paid monthly on the R5A form. The return must list the names and social security numbers of all staff and the month of payment, the amounts earned by weekly and fortnightly-paid workers, and the name and signature of the authorising officer.
The deadline is firm: payment is due within 14 days after the end of the preceding month. If the 14th lands on a weekend or public holiday, you must pay by the next business day to avoid a late fee.
The Education Levy follows the same calendar. It is remitted with the monthly payroll return by the 14th, and late submission attracts the same penalties as social security.
Self-employed persons file differently. After registering, they make an annual declaration of earnings at the end of each year, supplying the income information needed to set their contribution. The contribution year runs with the calendar year, from 1 January to 31 December.
Penalties, Surcharges, and Common Payroll Contribution Mistakes
Missing a deadline is expensive. A late social security payment carries a surcharge of 10% of the amount owed, applied where the due date falls on a weekend or holiday and payment is not made by the next business day.
Errors on the return cost money too. An incomplete or incorrect R5A submitted during the contribution month draws a fee of EC$100 per incorrect page.
Registration delays are penalised from the start of employment. Where an employer registers late, the penalty accrues from the actual date the worker began, which can produce a meaningful liability for a hire made months earlier.
Most failures are operational rather than legal. Manual tracking of leave accruals and contribution ceilings is the usual culprit, along with applying the wrong sector rate given the 1% gap between the 16% private and 15% public totals.
Confirm whether your entity files at the private-sector rate before your first remittance. A misclassified rate repeated each month compounds into a sizeable correction.
What This Means for Companies and Investors Hiring in Antigua and Barbuda
The headline for a foreign employer is the zero income tax position. Resident staff pay no tax on earnings, which lifts take-home pay relative to most Caribbean markets and can ease salary negotiations.
The cost you do carry is the contribution burden. On a private-sector salary up to the EC$6,500 monthly ceiling, the combined employer and employee statutory charge runs to roughly 23%: 16% for social security plus 7% for the MBS. The employer share alone is about 13%, made up of 9.5% social security and 3.5% MBS.
Above the ceiling the picture shifts. Social security stops at EC$6,500 a month, but the 3.5% employer MBS charge continues without limit on higher salaries.
Foreign nationals working legally are generally brought into the social security system on the same terms as local staff, and they accrue pension entitlements accordingly. Note that Antigua and Barbuda has no totalization agreement with the United States, so US social security and the local scheme do not coordinate; the country does maintain double taxation treaties with 12 jurisdictions, including Barbados, Belize, and Sweden.
International Business Companies carry a separate point worth flagging. Although an IBC enjoys a 50-year tax exemption, it remains liable for employer social security contributions on any staff it employs locally.
Recent Changes and Outlook for Payroll Contribution Rates
The most recent adjustment took effect on 1 January 2025. The public-sector rate moved to 15% from 14.5%, and the private-sector rate moved to 16% from 15.5%.
A pension change ran alongside it. The pensionable age rose to 65 effective 1 January 2025.
Both measures stem from the same source: the 10th and 11th Actuarial Reviews of 2014, which recommended a 0.5% annual increase to keep the scheme financially sustainable. That phased path was set in motion under Statutory Instrument 2016 No. 60.
MBS rates have held steady. The 7% combined charge has been stable for several years, and any change would require amending the Medical Benefits Regulations of 2011. You can check the current position through the Medical Benefits Scheme before running payroll.
Conclusion
For a foreign business owner, the payroll obligation story in Antigua and Barbuda is simpler than the headline might suggest, yet the execution details carry real financial risk. The absence of a standalone payroll tax removes one layer of complexity, but the combined weight of Social Security and Medical Benefits Scheme rates, the monthly earnings ceiling, and the penalty regime means that getting the calculation or the filing wrong still costs money.
The single most concrete action this decision drives is confirming correct employer registration and a reliable process for the R5A form before the first payroll runs, because penalties accumulate from the first missed deadline, not from any grace period.

Frequently Asked Questions
There is no standalone payroll tax statute, and personal income tax was abolished in 2016. What employers commonly call payroll tax is the combination of social security and Medical Benefits Scheme contributions, plus the Education Levy, all of which remain mandatory on staff wages.
A private-sector employer contributes 9.5% of insurable earnings to social security and 3.5% to the MBS, for an employer-side total of about 13%. The matching employee deductions bring the combined statutory charge to roughly 23% on earnings up to the ceiling.
Social security applies only up to EC$78,000 per year, or EC$6,500 per month, so contributions stop once a salary reaches that level. The MBS has no ceiling, meaning its 3.5% employer charge continues on the full gross pay of higher earners.
Contributions are reported on the R5A form and paid within 14 days after the end of the preceding month. If the 14th falls on a weekend or public holiday, payment is due by the next business day, and missing it triggers a 10% late fee.
Yes. Foreign nationals working legally are generally brought into the social security scheme on the same terms as local staff and accrue pension entitlements accordingly. They register using their home passport and a verified work permit issued through their employer.
No. An International Business Company enjoys a long-term tax exemption, but it still owes employer social security and MBS contributions for any staff it employs in the country.
