SO1 Return Jamaica — Annual Employer PAYE Return
Everything employers need to know about the SO1 form: what it is, who must file, the March 31 deadline, penalties for late filing, and how to generate it automatically with Payroll Jamaica.
What is the SO1 form in Jamaica?
The SO1 (also written S01) is the Statutory Declaration — Annual Return of Income Tax Deducted from Emoluments. It is the form every Jamaican employer must file with Tax Administration Jamaica (TAJ) at the end of each fiscal year.
The SO1 summarises all PAYE (Pay As You Earn) income tax that the employer deducted from employees' salaries throughout the tax year (April 1 – March 31) and remitted to TAJ. It serves as the annual reconciliation between the monthly P45 remittances you filed during the year and the total PAYE liability for each employee.
Each line on the SO1 lists an individual employee's TRN, name, gross emoluments, tax-free threshold applied, taxable income, and total PAYE deducted for the year. Alongside the SO1, employers must also issue a P24 (Certificate of Emoluments) to each employee, which is the employee's personal copy of their annual earnings and deductions.
Who must file the SO1 return?
Every employer registered with TAJ for PAYE must file the SO1 — regardless of the number of employees. This includes:
- Limited liability companies (Ltd)
- Sole traders with at least one employee
- Partnerships with paid staff
- Non-profit organisations, NGOs, and churches
- Government agencies and statutory bodies
- Schools, hospitals, and other institutional employers
If you registered as a PAYE employer during the tax year — even if you only employed staff for part of the year — you must still file an SO1 covering the period of employment. There is no exemption based on the size of your payroll or the amount of PAYE deducted.
When is the SO1 due?
The SO1 must be filed with TAJ by March 31 each year. Jamaica's tax year runs from April 1 to March 31, so the SO1 for the 2025/2026 tax year is due on March 31, 2026.
This is the same deadline as many other employer year-end obligations, including filing the annual NIS and NHT returns. See our March 31 payroll deadline guide for the full list of year-end obligations.
Key date
March 31, 2026 — SO1 filing deadline for the April 2025 – March 2026 tax year. If March 31 falls on a weekend or public holiday, TAJ typically expects filing by the last business day before the deadline.
PAYE rates reported on the SO1
The SO1 covers all PAYE deductions for the tax year. The current PAYE structure (2025/2026 tax year) is:
| Annual income band | PAYE rate |
|---|---|
| Up to J$1,902,360 | 0% (tax-free threshold) |
| J$1,500,097 – J$6,000,000 | 25% |
| Above J$6,000,000 | 30% |
Each employee's total PAYE for the year should reconcile with these rates applied to their gross emoluments minus the annual threshold. Use our payroll calculator to verify deductions before filing.
Penalties for late SO1 filing
Filing the SO1 after March 31 carries serious financial penalties:
- Late filing surcharge: TAJ imposes a penalty of up to J$50,000 per month (or part thereof) for each month the return is outstanding.
- Interest on underpaid PAYE: If the SO1 reveals that PAYE was under-remitted during the year, interest accrues on the shortfall from the original due date of each monthly payment.
- Prosecution risk: Persistent non-filers may face prosecution by TAJ. The Income Tax Act empowers TAJ to bring criminal charges for failure to file statutory declarations.
Beyond financial penalties, late filing delays your employees' ability to file their own annual tax returns and claim refunds — damaging employee trust and morale.
How to file the SO1 — step by step
Reconcile all monthly PAYE remittances
Before completing the SO1, reconcile every monthly P45 remittance you filed during the year with your payroll records. Ensure that the total PAYE deducted from each employee matches the sum of monthly deductions. Flag any discrepancies (missed months, over- or under-deductions) for correction.
Compile employee-level data
For each employee who received emoluments during the tax year, gather:
- Employee TRN (Taxpayer Registration Number)
- Full legal name
- Total gross emoluments for the year
- Tax-free threshold applied (standard: J$1,902,360)
- Taxable income (gross minus threshold and approved deductions)
- Total PAYE deducted
- Employment start and end dates (if applicable)
Complete the SO1 form
Fill in the SO1 form with your employer TRN, employer registration number, and the employee-level data compiled in Step 2. The form includes a summary section showing the total PAYE deducted across all employees and the total amount remitted to TAJ during the year. These two figures must match — any difference must be explained or settled before filing.
Generate P24 certificates for each employee
The P24 (Certificate of Emoluments) is the employee's personal record of their annual earnings and PAYE deductions. Employers must issue a P24 to every employee by March 31. Employees need this document to file their own individual income tax returns.
Submit to TAJ by March 31
Submit the completed SO1 form to TAJ. You can file:
- Online: Through the TAJ e-Services portal (eservices.taj.gov.jm)
- In person: At any TAJ Taxpayer Services office
- Via post: Mailed to TAJ (must be received by March 31)
Keep a signed copy for your records. TAJ recommends retaining payroll records and SO1 copies for at least seven years.
