On the Isle of Man, an employee who is not resident for tax purposes gets no personal allowance, so the employer applies code HR, and where only part of their duties is performed on the Island, tax must still come off the whole of their remuneration (Isle of Man Government). For 2026/27 the non-resident rate is 21% on all income (checked 14 September 2026) (Isle of Man Government). An employee whose duties are all performed off-Island may need no deduction, but only with prior clearance from the Income Tax Division. This is ITIP, the Island's own instalment scheme rather than UK PAYE, and the deduction is not split between Island days and days worked elsewhere. National Insurance runs on separate rules, and a new UK–Isle of Man agreement, approved by Tynwald on 17 June 2026, is due to change them for cross-border staff from 6 April 2027.

What tax code do you use for an employee who is not Isle of Man resident?
You use code HR, which the Income Tax Division defines as "No allowances and tax to be deducted at the higher rate using Table C" (Isle of Man Government). Non-residents have no allowance to code: gov.im says that "from 6 April 2010, the allowance has been reduced to £0" (Isle of Man Government). The test is the employee's residence for tax purposes, which our guide to Isle of Man tax residence explains.
The start of a tax year needs care. If no code has been issued for a non-resident employee, the employer "should not use any previous code, but should instead ensure that code HR is applied" (Isle of Man Government). Getting the code wrong carries a £250 penalty and leaves the employer liable for any underpaid employee ITIP (gov.im compliance table, archived 20 January 2025) (Isle of Man Government).
On a £60,000 salary with no pension contributions or other reliefs, the 2026/27 rates in Treasury practice note PN 227/26 (checked 14 September 2026) show what the code changes (Isle of Man Government):
| 2026/27, £60,000 salary | Resident, single allowance | Non-resident, code HR |
|---|---|---|
| Personal allowance | £17,000 | £0 |
| Taxed at 10% | £6,500, tax £650 | None |
| Taxed at 21% | £36,500, tax £7,665 | £60,000, tax £12,600 |
| Tax for the year | £8,315 | £12,600 |
PwC Isle of Man gives the same position: "Non-residents pay tax at a rate of 21% on total taxable income." Our guide to how Isle of Man payroll and ITIP work covers the scheme itself.
If your payroll mixes resident and non-resident staff, we can quote for running the right code for each from the first pay day.
Why do you deduct tax from the whole salary?
You deduct from the whole salary because gov.im's rule is that "where only part of the duties are performed in the Isle of Man, tax must be deducted from the whole of the remuneration", with code HR applied (Isle of Man Government). An employee who lives in England and spends one week a month at your Island office has tax deducted from their full salary, not just the pay for the Island weeks.
The deduction is a payment on account. ITIP paid over to the Division is "credited to the appropriate employee at the end of the tax year and offset against the income tax payable on that employee's assessment" (Isle of Man Government).
The 2018 UK–Isle of Man double taxation agreement sits alongside this rule. Under Article 14, pay a UK resident earns from employment exercised on the Island "may be taxed" on the Island, while pay for employment exercised elsewhere is taxable only in the UK (GOV.UK). The 183-day exception in Article 14(2) requires an employer that is not resident where the work is done, so it does not apply where a Manx-resident employer pays for the Island work. How the agreement shapes the employee's own bill is for the employee and their adviser, and this summary is not legal advice. Our guide to living on the Isle of Man and working in the UK covers the agreement from the other side.
When can you pay without deducting tax?
You can pay without deduction only when the employee performs all of their duties off-Island and the Division has given clearance in advance. gov.im's condition reads: "Where employees perform all of their duties off Island they may not require any tax to be deducted from their remuneration. However, prior clearance from the Division must be obtained in all such cases, otherwise the remuneration should be subject to the non-resident code HR" (Isle of Man Government).
The page says "may not require", not "will not", and clearance applies "in all such cases". Until the Division has cleared the employee, code HR applies to every payment, and if the employee then performs part of their duties on the Island, the whole-salary rule applies.
Clearance does not remove the paperwork. A cleared employee still needs a T20 when they start and a T14 at year end. Keeping track of where each person actually works is ongoing payroll work, and our guide on when to outsource payroll on the Isle of Man looks at when handing it over makes sense.

If you are unsure whether an employee's duties are all off-Island, ask us before the first pay day rather than after it.
What about National Insurance?
For staff moving between the Island and the UK, National Insurance currently works on one-area rules: the 1977 reciprocal agreement "Treats the IOM and the UK as a single area for liability to NIC" (Isle of Man Government). gov.im's detached-worker guidance adds that "where an employer in one country has staff working in the other country both the employee and employer will remain liable to National Insurance as though both were in the same country" (Isle of Man Government).
That liability has been tested in court. In 2012 a Manx employer argued the agreement could not make it pay employer contributions for staff in the UK, and on appeal "it was confirmed that the IOM employer was indeed liable to pay employer NIC for employees in the UK" (Isle of Man Government). Failing to deduct the correct amount "can result in the employer not only having to pay the employer NIC but also the employee NIC as well", and directors can be held personally liable for unpaid contributions. For someone sent to the Island from another agreement country, such as Ireland, Jersey or the United States, a certificate of detachment "will allow them to continue to pay contributions to their home country" (Isle of Man Government).
A new agreement will change this. Tynwald approved the Order giving it effect on 17 June 2026 (Tynwald), and it is due to come into operation on 6 April 2027 (Tynwald); the Department for Enterprise said on 22 May 2026 that the agreement also needs UK ratification to come into force on that date (Isle of Man Department for Enterprise). The Order's explanatory note sets the general rule: contributions "will normally only be payable in the territory a person works in". HMRC's guidance for the UK side says that rule applies "irrespective of where the worker resides within the UK or the Isle of Man or where their employer is based" (GOV.UK), and an employer with no registered office or place of business in that territory "will be obligated to pay the National Insurance in the territory where the employee is working". Two exceptions matter to employers: under paragraph 24, someone who normally works as an employee in both places is subject only to the rules where they live, and workers posted temporarily for up to 3 years can apply for a certificate of coverage. On those terms, a Manx employer whose remote employee lives and works only in the UK, with no temporary posting, would owe UK contributions once the agreement has effect.
What needs care at year end?
At year end, every non-resident employee needs a T14, even if no tax was deducted, and the T14s go to the Division with your T37 Employer's Annual Return. gov.im's employer guidance says a T14 "must also be completed for each employee including students and schoolchildren (under 16 years of age) and non-residents" (Isle of Man Government). The Online Services help page, checked 14 September 2026, describes completing the T37 with its T14s and T9s as "a statutory obligation" (Isle of Man Government Online Services).

The deadlines and penalties below come from gov.im's employer compliance table (archived 20 January 2025) (Isle of Man Government); the 5 May date, and the T14s as "related form(s)" of the T37, match the Online Services help page on 14 September 2026 (Isle of Man Government Online Services):
| Form | Deadline | If missed |
|---|---|---|
| T20, employee starting | Within 14 days of the start | £250 |
| T14, one per employee | With the annual return, even with no deductions | As for the T37, as a related form |
| T37 Employer's Annual Return | Within 30 days after the end of the tax year (by 5 May) | £250, then £50 a day until submitted |
Year-end payroll for a mix of resident and non-resident staff sits within our accounting and back-office support for Isle of Man businesses.
If you would rather hand the T37 and the monthly returns behind it to someone else, we can quote for a payroll that includes off-Island staff.
Frequently asked questions
Does a non-resident employee get a personal allowance? No. The allowance for non-residents has been £0 since 6 April 2010, which is why their pay runs on code HR, and PN 227/26 sets the non-resident rate at 21% for 2026/27.
Do I need clearance before paying without tax? Yes. Even where every duty is performed off-Island, gov.im says "prior clearance from the Division must be obtained in all such cases"; until then, code HR applies.
What happens if the employee moves to the Island mid-year? Keep operating the code you have until a revised one arrives: the Division tells employers to "continue to operate the code in use until a revised code is issued to you by the Income Tax Division". gov.im also asks employers to tell the employee to contact the Division about the change.
Does this apply to a non-resident director? ITIP covers "office holders such as directors" (Isle of Man Government), and Article 15 of the 2018 agreement lets the Island tax directors' fees that a Manx-resident company pays to a UK resident. A director's company-law duties are a separate question.
