The new tax year started April 1, 2026. Your first payroll of the 2026/2027 fiscal year has been processed — or it should have been. Now comes the part that determines whether you start the year compliant or start the year behind.
Your first S01 monthly return is due May 14, 2026. It covers all payroll processed in April 2026, and it sets the baseline for your entire tax year. Get this one right, and every subsequent monthly filing builds on a clean foundation. Get it wrong, and you carry the error forward until reconciliation catches it — or TAJ does.
What Is the S01 Monthly Return?
The S01 return (also called the employer's monthly return or statutory deduction return) is the form Jamaican employers file with Tax Administration Jamaica (TAJ) every month. It reports:
- Total gross emoluments paid to all employees during the month
- PAYE (income tax) deducted from employees
- NIS contributions deducted from employees
- Education Tax deducted from employees
- Employer NIS contributions (3% of gross, up to the ceiling)
- Employer Education Tax (3.5% on statutory income (gross minus NIS))
- Employer NHT contributions (3% of gross)
- HEART/NSTA levy (3% of gross, employer only)
The return is due by the 14th of the following month. April's payroll return is due May 14. May's payroll return is due June 14. And so on through March 2027.
Why the First S01 of the Year Is Different
The May 14 filing is not just another monthly return. It is the first return of a brand-new tax year, which means:
1. Cumulative PAYE Starts from Zero
PAYE in Jamaica is calculated on a cumulative basis. Each month, your payroll system should compare the employee's year-to-date earnings against the year-to-date tax threshold to determine how much PAYE is owed.
In April, with no prior months to consider, the calculation is straightforward:
- Monthly tax threshold: J$158,530 (2026/27 tax year)
- If an employee earns J$200,000 in April, their taxable income is J$200,000 minus J$158,530 = J$41,470
- PAYE due: J$41,470 x 25% = J$10,368
From May onward, the cumulative method kicks in. The system compares two months of earnings against two months of threshold. This is why getting April right matters — if the April PAYE figure is wrong, every subsequent month's cumulative calculation compounds the error.
2. NIS Ceiling Tracking Resets
The NIS contribution ceiling of J$5,000,000 per year resets on April 1. For high earners who hit the ceiling partway through the previous year, NIS deductions resume in April and continue until the new ceiling is reached.
Your first S01 must reflect NIS deductions for all employees, including those who were exempt from NIS at the end of the prior tax year due to the ceiling.
3. New Employees Need Correct Setup
If you hired staff in April, their first appearance on an S01 return will be in this filing. Verify that every new hire has:
- A valid TRN (Taxpayer Registration Number)
- A valid NIS number (or that a registration application has been submitted)
- An NHT number
- Correct salary and pay frequency entered in your system
Missing or incorrect employee identifiers on the S01 will cause TAJ processing errors.
What to Include in Your May 14 S01 Return
Here is the complete data set required for the April 2026 S01:
For Each Employee
| Field | What to Report | |---|---| | Employee name | As registered with TAJ | | TRN | 9-digit Taxpayer Registration Number | | NIS number | National Insurance number | | Gross emoluments | Total gross pay for April 2026 | | PAYE deducted | Income tax withheld for April | | NIS (employee) | 3% of gross (subject to ceiling) | | Education Tax (employee) | 2.25% on statutory income (gross minus NIS) |
Employer Totals
| Contribution | Rate | Base | |---|---|---| | Employer NIS | 3% | Gross emoluments (subject to J$5M annual ceiling) | | Employer NHT | 3% | Gross emoluments (no ceiling) | | Employer Education Tax | 3.5% | Gross emoluments (no ceiling) | | HEART/NSTA | 3% | Gross emoluments (no ceiling) |
Payment Due
The total amount remitted with the S01 must equal:
Employee deductions (PAYE + NIS + Education Tax) plus employer contributions (NIS + NHT + Education Tax + HEART/NSTA)
All of this is payable to TAJ by May 14, 2026. NHT contributions may be remitted separately through the NHT portal.
How to File the S01 Return
Step 1: Log in to the TAJ Online Portal
Go to tax.gov.jm and sign in with your employer credentials. If you do not have an online account, register at the nearest TAJ office — you will need your employer TRN and company registration documents.
Step 2: Navigate to Employer Returns
Select the S01 monthly return option. Choose the return period: April 2026.
Step 3: Enter Employee-Level Data
For each employee, enter the gross emoluments, PAYE, NIS, and Education Tax for the month. If you are filing for more than 10 employees, TAJ accepts bulk upload via CSV. The format specification is available on the TAJ portal.
Step 4: Enter Employer Contributions
Input the employer's share of NIS, Education Tax, NHT, and HEART/NSTA.
Step 5: Review and Submit
Verify that:
- Total employee deductions match your payroll register
- Total employer contributions are calculated at the correct rates
- Every employee TRN and NIS number is present and valid
- The total payment amount matches the sum of all deductions and contributions
Submit the return and make the corresponding payment via the TAJ payment gateway (bank transfer, credit card, or over-the-counter at a TAJ-approved location).
Step 6: Keep Your Confirmation
Save the confirmation number and receipt. You will need it if TAJ queries any amount during the year or at annual reconciliation.
Common Mistakes on the First S01 of the Year
1. Carrying over last year's cumulative PAYE If your system did not reset on April 1, the PAYE calculation for April will be based on the prior year's cumulative earnings. This produces wildly incorrect figures. The fix is immediate: reset year-to-date fields before running April payroll.
2. Missing the NIS ceiling reset Employees who hit the J$5M NIS ceiling in 2025/2026 should have NIS deductions resume in April 2026. If your system still shows them as "ceiling reached," they will be under-contributed for the new year.
3. Using outdated rates If the government adjusts any statutory rate effective April 1, your system must reflect the change before the first payroll run. Always check TAJ announcements in late March for any updates.
4. Omitting new hires Employees who started in April must appear on the S01 even if they only worked part of the month. Pro-rate their earnings but do not exclude them.
5. Filing late because "it's just the first month" TAJ applies penalties from the 15th onward with no exception for the first return of the year. The penalty for late filing is a percentage of the tax due plus interest on the outstanding amount. There is no grace period.
What Happens If You Miss May 14?
Late filing of the S01 triggers:
- Penalty: A surcharge on the outstanding tax amount
- Interest: Accrues daily from May 15 onward
- Compliance flag: Late filers are flagged in TAJ's system, increasing audit probability for the rest of the tax year
If you realize you cannot file by the 14th, file as soon as possible. The penalty and interest are calculated on the number of days late — every day you delay costs more.

May 14 Filing Timeline
| When | What to Do | |---|---| | April 1–30 | Process all April payroll runs | | May 1–7 | Review April payroll totals and verify all deductions | | May 7–10 | Generate S01 return data and reconcile against payroll register | | May 10–13 | Submit S01 via TAJ portal and make payment | | May 14 | Deadline — return and payment must be received by TAJ |
Do not wait until May 14 to start. If there is an error in your data, you need time to correct it before the deadline.
Bottom Line
The first S01 return of the 2026/2027 tax year is due May 14, 2026. It covers April payroll and sets the cumulative baseline for the entire year. Every rate must be correct, every cumulative figure must start from zero, and every employee must be accounted for.
This is the return that determines whether your year starts clean or starts with a compounding error.
