đŸ‡¿đŸ‡¦ Ireland–South Africa Double Tax Treaty: Who Taxes What When You Live in Ireland
Ireland and South Africa have a double tax treaty in force, which is more than most African countries have with Ireland. It doesn't remove South African tax by itself, but it decides which country gets the first claim on each kind of income, and it can settle the residence question that worries most South Africans who move here.
- The treaty (in effect since 1998, amended by a 2010 protocol) gives Ireland the right to tax your salary for work done here.
- South Africa can tax rent and gains on South African property, its dividends tax is limited to 10% for individuals, and interest goes to the country where you live.
- Its tie-breaker can make you resident only in Ireland, and SARS says that ends your South African tax residence, with an exit charge.
If you're not Irish-domiciled, the dividend and interest reliefs cover only income you bring into Ireland. For the Irish refund side, see our guide for South African workers and the tax refund calculator.
Is there a tax treaty between Ireland and South Africa?
- Yes: signed on 7 October 1997, it has applied in Ireland since 6 April 1998 for income tax and CGT.
- A protocol signed on 17 March 2010 rewrote the dividends article from 1 April 2012 and the exchange-of-information article from 1 January 2013.
- Since 2023 the OECD multilateral instrument has also applied, adding an anti-abuse test and changing the rule for property-rich shares.
- The texts. Revenue publishes the convention, the 2010 protocol and a synthesised text with the OECD multilateral instrument on its South Africa treaty page. Effective dates are on Revenue's dates of effect table.
- One of six in Africa. Ireland's treaties in effect in Africa are with South Africa, Egypt, Morocco, Zambia, Botswana and Ethiopia. Kenya and Ghana have signed treaties that aren't yet in effect; Nigeria, Uganda and Zimbabwe have none (see our Ireland–Nigeria guide).
- What a treaty doesn't do. It doesn't create Irish reliefs or replace your Irish return. You still claim credits, declare foreign income and file in Ireland the normal way; the treaty only decides which country may tax each item and how the other gives relief.
Which country taxes you if both say you're resident?
- Article 4 breaks the tie in a fixed order: permanent home, centre of vital interests, habitual abode, nationality, then agreement between the tax authorities.
- If it lands on Ireland, SARS says you also stop being a South African tax resident.
- That triggers a deemed disposal of your worldwide assets except South African immovable property.
You can be resident in both countries under their own laws at the same time. Ireland counts days: 183 in a tax year, or 280 over this year and last with more than 30 this year (Revenue). South Africa asks whether you're ordinarily resident there, or meet a physical presence test of more than 91 days in the year and each of the five before it plus more than 915 days over those five years (PwC South Africa, reviewed May 2026). When both apply, the treaty decides:
| Step | The test in Article 4(2) | What it usually means for someone who moved to Ireland |
|---|---|---|
| 1 | Where you have a permanent home available to you | A rented or owned home in Ireland counts; a South African house let to tenants usually isn't available to you |
| 2 | If you have one in both: where your personal and economic relations are closer (centre of vital interests) | Where your spouse and children live, where you work and where your life is run |
| 3 | If that can't be decided, or you have a permanent home in neither: where you have a habitual abode | Where you actually spend most of your time |
| 4 | If still undecided: your nationality | The country you're a national of |
| 5 | Otherwise: mutual agreement between Revenue and SARS | The two authorities settle it between them |
- SARS accepts the treaty result. Its cessation page says a person who becomes a tax resident of another country under a double taxation agreement also ceases to be a resident for tax purposes in South Africa.
- Ceasing residence has a price. SARS treats your worldwide assets, apart from South African immovable property and a few other exclusions, as disposed of when you break residence, so growth in shares and funds can create a South African CGT bill even though you sold nothing. That's the decision our South African workers guide walks through.
- You tell SARS; it doesn't happen silently. SARS asks for a RAV01 update with the cessation date and a declaration with supporting documents; for the treaty route, that includes a foreign tax residence certificate. Our guide to ceasing South African tax residency covers the process, the exit tax and your retirement annuity.
- The Irish certificate. Revenue issues a Letter of Residence through myAccount once it's satisfied you're Irish resident for the year (Revenue manual 35-01-05). It supports your position, but SARS reaches its own conclusion under South African law, so the tie-breaker analysis is one for a South African tax practitioner.
Can South Africa tax your Irish salary?
- Ireland taxes pay for work you do here (Article 15), except on a short assignment covered by Article 15(2).
- South Africa can tax it too only while you're still South African resident, and must then give relief for the Irish tax.
- If the tie-breaker (applied year by year) makes you resident only in Ireland, South Africa loses that right, but you must still notify SARS and evidence the cessation.
- If you're resident only in Ireland under the treaty. Your salary is taxed in Ireland under PAYE, with the same credits and bands as anyone else. Nothing is due to SARS on it from the date you cease to be resident, once SARS has that date, though you file a South African return for the year up to that date.
- If SARS still treats you as resident. South Africa taxes residents on worldwide income, but it exempts the first R1.25 million of foreign employment income if you spent more than 183 full days outside South Africa in a 12-month period, including a continuous period of more than 60 full days (SARS). It covers employment remuneration only, not contractor income or South African public-sector pay. On anything above that, Article 23(2) requires South Africa to deduct the Irish tax, capped at the South African tax on that income.
- Short assignments are different. If you're South African resident and work in Ireland for an employer not resident in Ireland for no more than 183 days in any 12 months, with the pay not borne by an Irish branch, Article 15(2) leaves the salary taxable only in South Africa.
How are rent and property in South Africa taxed?
- South Africa can tax rent and gains from South African property (Articles 6 and 13).
- If Ireland taxes the same income, because you're Irish-domiciled or bring the money in, Article 23(1) credits the South African tax against the Irish tax.
- That credit is worth more than the deduction you'd get from a country without a treaty.
- Rent from a house in South Africa. Taxable in South Africa as the property's country. In Ireland it's foreign rental income: if you're Irish-domiciled it's taxed as it arises; if you're not, generally only what you bring into Ireland, with no deduction for expenses (Revenue, foreign rental income). Where Irish tax is due, the South African tax on the same rent is credited.
- Selling a South African property. South Africa keeps the right to tax the gain, and the exit charge never applies to South African immovable property. An Irish resident is within Irish CGT (31% for disposals from 7 October 2026; 33% still applies to development land) on the gain if Irish-domiciled, or, if not, on the gain to the extent the proceeds are brought into Ireland, with credit for the South African tax. Our South African workers guide works through a €80,000 gain.
- Shares in property-rich companies. Since the OECD multilateral instrument took effect (for individuals, from the 2024 Irish tax year and the South African year of assessment starting 1 March 2024), South Africa can tax gains on shares or comparable interests, such as partnership or trust interests, that derived more than 50% of their value from South African immovable property at any time in the 365 days before the sale, whether or not they're listed (Article 13(2), as replaced by Article 9(4) of the MLI, in Revenue's synthesised text).
- Other assets. Gains on other property, such as most listed shares, are taxable only in the country where you're resident under the treaty (Article 13(5)). Article 13(6) lets South Africa still tax, under its own law, gains on assets you owned before moving if you sell within three years of having been South African resident.
What about South African dividends, interest and pensions?
- South African dividends tax is 20%, but the treaty caps it at 10% for an individual resident in Ireland who gives the payer a declaration.
- Interest from South Africa is taxable only in Ireland; if you're not Irish-domiciled, both reliefs cover only income you bring in (Article 23(5)).
- Pensions arising in South Africa may be taxed there, and government pensions generally only there.
| Income from South Africa | Treaty rule | What it means in practice |
|---|---|---|
| Dividends | Article 10 as replaced by the 2010 protocol: South Africa may tax at no more than 10% for individuals (5% for qualifying companies) | Give your platform or the company the non-resident declaration and undertaking, or it withholds the domestic 20%; if you're not Irish-domiciled, the cap covers only dividends brought into Ireland |
| Interest | Article 11: taxable only in the country where you're resident, if you're the beneficial owner | Interest on South African savings is an Irish matter once you're treaty-resident here |
| Private pensions and annuities | Article 18: may be taxed in South Africa | Ireland can tax them too as a resident's income (on what you bring in if you're not Irish-domiciled), with credit for the South African tax |
| Government pensions | Article 19(2): generally taxable only in South Africa | Taxable only in Ireland if you're both resident in Ireland and an Irish national (Article 19(2)(b)) |
The dividends tax rate and the declaration rule are on SARS's dividends tax page. Declarations submitted from 1 July 2020 may be valid for only five years, so check with your withholding agent whether yours needs renewing.
Worked example: dividends from a South African portfolio
- Lindiwe, resident only in Ireland under the treaty, receives R40,000 of dividends from JSE-listed shares and brings them into Ireland.
- The declaration is worth R4,000 a year: without it, dividends tax at 20% takes R8,000; with it, the 10% treaty cap takes R4,000.
Starting data (assumptions): Lindiwe is a nurse in Galway, resident only in Ireland under Article 4 and not Irish-domiciled. She keeps a South African share portfolio through a local platform, which pays her R40,000 of dividends in the year. She transfers the dividends to her Irish bank account in the same year.
| Calculation | Dividends tax | |
|---|---|---|
| No declaration: domestic rate | R40,000 Ă— 20% | R8,000 |
| Declaration given: treaty cap | R40,000 Ă— 10% | R4,000 |
| Saved by the declaration | R8,000 − R4,000 | R4,000 |
Because she brings the dividends into Ireland, they're taxable here as foreign income under the remittance basis, and the R4,000 of South African tax is credited against the Irish tax on them. The transfer also matters for the treaty rate: under Article 23(5), when Ireland taxes a non-domiciled individual only on what's brought in, South Africa's treaty relief applies only to the amount brought into Ireland, so dividends left in South Africa can be taxed at the full 20%. If she were Irish-domiciled, Ireland would tax the dividends as they arise, with the same credit, and the 10% cap would apply to all of them.
Is there still a SARS emigration tax clearance?
- Not under that name: financial emigration, the old exchange-control route, ended on 1 March 2021.
- You now cease tax residence through SARS's own process.
- Moving larger sums out of South Africa goes through a Tax Compliance Status PIN for an Approval International Transfer (AIT).
- Ceasing residence. RAV01 update with the date residence ended, then a declaration with a motivation letter, passport or travel record and, on the treaty route, a foreign tax residence certificate (SARS). SARS can decline a declaration that doesn't meet the criteria.
- Moving money out. SARS's Approval International Transfer covers residents transferring funds abroad and people who have ceased tax residence. The single discretionary allowance was raised from R1 million to R2 million a year by the Reserve Bank's exchange control circulars of 8 April 2026 (Moonstone). Check the current limits with your bank or a South African adviser.
- Retirement annuities. Access to South African retirement annuity funds after leaving is generally tied to three consecutive years of non-residence; see our South African workers guide.
What Revenue actually asks for
- A Letter of Residence from myAccount, if SARS needs proof.
- Your South African income declared on your Irish return, where Ireland taxes it.
- Evidence of the South African tax you paid, if you claim the treaty credit.
- Letter of Residence: request it in myAccount for each year SARS asks about; Revenue checks it against its records before issuing it.
- Declare foreign income that Ireland taxes (all of it if you're Irish-domiciled, what you brought in if you're not) on your Income Tax Return. A PAYE worker can use Form 12 if taxable non-PAYE income is €5,000 or less and gross non-PAYE income €30,000 or less; otherwise Form 11.
- Claim the credit for South African tax on the same income, keeping the South African assessment or withholding statements as proof.
- Keep a record of your days in each country and of where your home, family and work were, year by year: it's the evidence for the tie-breaker.
- Claim your Irish credits and reliefs for every open year; 2022 closes on 31 December 2026.
Where do you start?
Work out where the tie-breaker puts you for each year since you moved. That one answer decides whether SARS still has a claim on your salary, whether the exit charge has already been triggered, and how every other line in this guide applies to you.

Questions we get asked
Is there a double tax treaty between Ireland and South Africa?
Yes. It was signed on 7 October 1997, has applied in Ireland since 6 April 1998 for income tax and CGT, and was amended by a protocol signed on 17 March 2010, which took effect for dividends from 1 April 2012 and otherwise from 1 January 2013.
Can SARS tax my Irish salary?
Only while you're still South African resident, and then South Africa must give relief for the Irish tax, after exempting the first R1.25 million of qualifying foreign employment income if you meet the days-abroad tests. If the treaty's tie-breaker makes you resident only in Ireland, SARS says you cease to be South African resident, so your Irish salary falls outside its reach once you've notified SARS of the cessation and can evidence it.
Does the treaty mean I only pay tax in one country?
Not always. Some income can be taxed in both, such as rent from South African property; the treaty then makes the country of residence give a credit for the other's tax. Interest is taxable only where you live, and South African dividends tax is capped at 10% for individuals, though if you're not Irish-domiciled both reliefs apply only to income you bring into Ireland.
How do I prove to SARS that I'm Irish resident?
Request a Letter of Residence in myAccount for the year. Revenue issues it once it's satisfied you're resident. SARS asks for a foreign tax residence certificate when you cease residence under a treaty, but it reaches its own conclusion.
Does becoming treaty-resident in Ireland trigger the South African exit charge?
SARS treats your worldwide assets, other than South African immovable property, as disposed of when you break South African residence, and its cessation page lists the treaty route as one way of doing that. Plan the timing with a South African tax practitioner.
