1.—AGREEMENT DATED 14th APRIL, 1926.

AGREEMENT BETWEEN THE BRITISH GOVERNMENT AND THE GOVERNMENT OF THE IRISH FREE STATE IN RESPECT OF DOUBLE INCOME TAX.

The British Government and the Government of the Irish Free State, being desirous of concluding an Agreement for the reciprocal exemption from income tax and super-tax of persons who are resident in Great Britain (including Northern Ireland) or in the Irish Free State but are not resident in both countries and for the reciprocal granting of relief from double taxation in respect of income tax (including super-tax) to persons who are resident in both countries, and being desirous of making such supplemental, consequential and incidental provisions as appear necessary or proper for the purposes of such Agreement, have agreed as follows:—

1. (a) Any person who proves to the satisfaction of the Commissioners of Inland Revenue that for any year he is resident in the Irish Free State and is not resident in Great Britain or Northern Ireland shall be entitled to exemption from British income tax for that year in respect of all property situate and all profits or gains arising in Great Britain or Northern Ireland and to exemption from British super-tax for that year.

(b) Any person who proves to the satisfaction of the Revenue Commissioners that for any year he is resident in Great Britain or Northern Ireland and is not resident in the Irish Free State shall be entitled to exemption from Irish Free State income tax for that year in respect of all property situate and all profits or gains arising in the Irish Free State, and to exemption from Irish Free State super-tax for that year.

(c) Exemption under this Article may be given either by discharge or by repayment of tax, or otherwise, as the case may require.

3. (a) Any person who is entitled to exemption from British income tax by virtue of Article 1 (a) of this Agreement in respect of property situate and profits or gains arising in Great Britain or Northern Ireland shall, if and so far as the Oireachtas of the Irish Free State so provides, and subject to any exemption or relief to which he may be entitled under the laws in force in the Irish Free State, be chargeable to Irish Free State income tax in respect of such property, profits or gains.

(b) Any person who is entitled to exemption from Irish Free State income tax by virtue of Article 1 (b) of this Agreement in respect of property situate and profits or gains arising in the Irish Free State shall, if and so far as the British Parliament so provides, and subject to any exemption or relief to which he may be entitled under the laws in force in Great Britain and Northern Ireland, be chargeable to British income tax in respect of such property, profits or gains.

(c) Any person who is entitled to relief by virtue of Article 2 of this Agreement shall, subject to such relief, be chargeable, if and so far as the British Parliament so provides, to British income tax in respect of property situate and profits or gains arising in the Irish Free State in like manner in all respects as if he were resident in Great Britain or Northern Ireland but not resident in the Irish Free State and shall, subject to such relief as aforesaid, be chargeable, if and so far as the Oireachtas of the Irish Free State so provides, to Irish Free State income tax in respect of property situate and profits or gains arising in Great Britain or Northern Ireland in like manner in all respects as if he were resident in the Irish Free State but not resident in Great Britain or Northern Ireland.

4. For the purposes of this Agreement a company, whether incorporated by or under the laws of Great Britain or of Northern Ireland or of the Irish Free State or otherwise, shall be deemed to be resident in that country only in which its business is managed and controlled.

5. The Commissioners of Inland Revenue and the Revenue Commissioners may from time to time make arrangements generally for carrying out this Agreement and may in particular make such arrangements as may be practicable to avoid the collection of both British and Irish Free State income tax on the same income without allowance for any relief due under this Agreement, and the Commissioners of Inland Revenue and the Revenue Commissioners may make such regulations as they respectively think fit for carrying out such arrangements.

6. The obligation as to secrecy imposed by any enactment with regard to income tax shall not prevent the disclosure by any authorised officer of the British Government to any authorised officer of the Government of the Irish Free State or by any authorised officer of the Government of the Irish Free State to any authorised officer of the British Government of such facts as may be necessary to enable full effect to be given to this Agreement.

7. Any question that may arise between the parties to this Agreement as to the interpretation of this Agreement or as to any matter arising out of or incidental to the Agreement shall be determined by such tribunal as may be agreed between them, and the determination of such tribunal shall, as between them, be final.

8. This Agreement shall be subject to confirmation by the British Parliament and by the Oireachtas of the Irish Free State and shall have effect only if and so long as legislation confirming the Agreement is in force both in Great Britain and Northern Ireland and in the Irish Free State.

(d) the appropriate rate of Irish Free State tax for any year shall in the case of a person whose income is chargeable in the Irish Free State to income tax only be a rate ascertained by dividing the amount of tax payable by him for that year in respect of his total income (before deduction of any relief granted in respect of life assurance premiums or any relief granted under the provisions of Section 27 of the Finance Act, 1920 , as amended by this Article) by the amount of his total income, and shall in the case of a person whose income is chargeable to Irish Free State sur-tax be the sum of the following rates:—

(e) relief under this Article from British income tax allowable to any person for any year shall be given as to such an amount as would be due if his income for the year were chargeable to British income tax at the standard rate only and to Irish Free State income tax only by repayment of or set off against the tax at the standard rate payable by him for that year, and as to any balance by repayment of or set off against any British sur-tax payable by him for that year;

(f) relief under this Article from Irish Free State tax allowable to any person for any year shall be given as to such an amount as would be due if his income for the year were chargeable to British income tax at the standard rate only and to Irish Free State income tax only by repayment of or set off against the income tax payable by him for that year, and as to any balance by repayment of or set off against any Irish Free State sur-tax payable by him for that year.

4.—AGREEMENT DATED 4th APRIL, 1959.

AGREEMENT BETWEEN THE GOVERNMENT OF IRELAND AND THE GOVERNMENT OF THE UNITED KINGDOM WITH RESPECT TO CERTAIN EXEMPTIONS FROM TAX.

The Government of Ireland and the Government of the United Kingdom, Considering the Agreement of the 14th April, 1926, between the Government of the Irish Free State and the British Government, in pursuance of which exemptions from tax are conferred on persons resident in one only of the countries from tax under the law of the other,

Considering that doubts have arisen as to the effect on the said exemptions of the provisions of subsection (2) of Section four of the United Kingdom Finance (No. 2) Act, 1955 (hereinafter called “the Act of 1955”) and subsection (2) of section fifty-one of the Irish Finance Act, 1958 (hereinafter called “the Act of 1958”) (which relate to purchases of shares by persons exempted from tax),

Desiring to remove these doubts for the year 1959-60 and subsequent years,

Have agreed as follows:—

Article 1.

(1) The said exemptions fall within, and are subject to, the said provisions of the Act of 1955 and the Act of 1958.

(2) Subject as aforesaid the said Agreement of 1926 as amended by Agreements made on the 25th April, 1928, and the 21st July, 1947, continues in force.

(3) Paragraph (1) of this Article does not relate to cases where the dividend in respect of which exemption is claimed is one on a holding of shares or stock acquired by the person claiming exemption, or regarded as having been acquired by him, before the eighth day of April, nineteen hundred and fifty-nine except in so far as that dividend is one falling within subsection (2) of the said Section four or subsection (2) of the said Section fifty-one by reason (directly or indirectly) that in respect of another dividend, received by a body corporate other than the person claiming exemption from a holding of shares or stock acquired, or regarded as acquired, by the body corporate on or after the said eighth day of April, a deduction is to be made in determining the income of that body corporate arising after a given date; but this paragraph is without prejudice to any question as to the application of the said provisions of the Act of 1955 and the Act of 1958 in circumstances to which paragraph (1) of this Article does not relate.

Article 2.

This Agreement shall become effective on the exchange of notes confirming that the necessary steps have been taken to give it the force of law in Ireland and the United Kingdom, and thereafter shall remain effective only so long as it has the force of law in both countries.

5.—AGREEMENT DATED 23rd JUNE, 1960.

AGREEMENT BETWEEN THE GOVERNMENT OF IRELAND AND THE GOVERNMENT OF THE UNITED KINGDOM WITH RESPECT TO CERTAIN EXEMPTIONS FROM TAX.

The Government of Ireland and the Government of the United Kingdom,

Considering the Agreement of the 14th April, 1926, between the Government of the Irish Free State and the British Government in pursuance of which exemptions from tax are conferred on persons resident in one only of the countries from tax under the law of the other,

Considering that legislation may be enacted in either country to maintain the proper incidence of liability to income tax and to prevent the obtaining of undue tax advantages,

Considering that such legislation may be insufficiently effective unless, as well as applying to persons resident in the country where it is enacted, it applies also to persons not so resident but resident in the other of the two countries and accordingly affects exemptions from tax conferred in pursuance of the said Agreement of 1926,

Recognising that the legislation which was the subject of the Agreement of the 4th April, 1959, made between the two Governments affected the said exemptions in particular ways, and desiring to supplement that Agreement by a more general Agreement,

Desiring to declare that save as provided by this Agreement the continuance in force of the said Agreement of 1926 shall not be affected by the enactment of such legislation,

Have agreed as follows:—

Article 1.

Legislation enacted in either country at any time after the date of this Agreement and affecting in any way exemptions from income tax of that country of persons resident in that country shall, except as otherwise provided by the legislation and subject to the next following Article of this Agreement, have the like effect on exemptions from that tax which persons enjoy as not resident in that country but resident in the other of the two countries, and the enactment of such legislation shall not affect the continuance in force of the said Agreement of 1926, as amended by Agreements of the 25th April, 1928, the 21st July, 1947, and the 4th April, 1959, and this Agreement.

Article 2.

If the Government of either country represents that any provisions of legislation enacted in the other country, being provisions falling within Article 1 of this Agreement, are nevertheless not within the intention of the Agreement, the two Governments shall consult and if they agree that Article 1 ought not to apply the Government of the country in which the legislation was enacted shall take the necessary steps to secure that the said provisions shall not affect, or be deemed to have affected, exemptions from the income tax of that country which persons enjoy as not resident therein but resident in the other country.

Article 3.

This Agreement shall become effective on the exchange of notes confirming that the necessary steps have been taken to give it the force of law in Ireland and the United Kingdom, and thereafter shall remain effective only so long as it has the force of law in both countries.

Dated this 23rd day of June, 1960.

PART II

Provisions of Section 27 of the Finance Act, 1920, re-enacted as they apply in relation to British Income Tax.

Section 355 .

(1) If any person who has paid, by deduction or otherwise, or is liable to pay, Irish income tax (including sur-tax) for any year of assessment on any part of his income proves to the satisfaction of the Special Commissioners that he has paid British income tax for that year in respect of the same part of his income, he shall be entitled to relief from Irish income tax (including sur-tax) paid or payable by him on that part of his income at a rate thereon to be determined in accordance with the provisions in that behalf of Article 2 of the Agreement dated the 25th day of April, 1928, which Agreement is set out in Part I of this Schedule.

(2) Where a person has not established his claim to relief under this section for any year of assessment before the first day of January in that year, the relief shall be granted by way of repayment of tax.

(3) Notwithstanding anything in the provisions applicable to Case III of Schedule D or in any other provision of this Act, no deduction shall be made on account of the payment of British income tax in estimating income for the purposes of Irish income tax, and where income tax has been paid or is payable in Great Britain and Northern Ireland either on the income out of which income subject to Irish income tax arises or is received, or as a direct charge in respect of that income, the income so subject to Irish income tax shall be deemed to be income arising or received after deduction of British income tax and an addition shall, in estimating income for the purposes of Irish income tax, be made to that income of the proportionate part of the income tax paid or payable in Great Britain and Northern Ireland in respect of the income out of which that income arises or is received together with the full amount of any British income tax directly charged or chargeable in Great Britain and Northern Ireland in respect of that income:

Provided that where any income arising or received as aforesaid consists of dividends which are entrusted to any person in Ireland for payment and the Special Commissioners are satisfied that the person so entrusted is not in a position to ascertain the amount of the addition to be made under this subsection, the assessment and charge may be made on the amount of the dividends as received by the person so entrusted, but in any such case the amount of the addition shall be chargeable on the recipient of the dividends under Case IV of Schedule D.

In the foregoing proviso the expression “dividends” includes any interest, annuities, dividends, shares of annuities, or other annual payments in respect of which tax is charged under the provisions of Part III of this Act or under Part XXXI.

(4) The Revenue Commissioners may from time to time make regulations generally for carrying out the provisions of this Part of this Schedule, and may, in particular, by those regulations provide:—

(a) For making such arrangements with the British Government as may be necessary to enable the appropriate relief to be granted;

(b) For prescribing the year which, in relation to any British income tax, is, for the purposes of relief under this Part of this Schedule, to be taken as corresponding to the year of assessment for the purposes of Irish income tax.

PART III

Provisions for Giving Effect to Agreements set out in Part I of this Schedule

Section 355 .

1. In respect of property situate and profits or gains arising in Great Britain or Northern Ireland:

(1) The provisions applicable to Case III of Schedule D contained in Chapter IV of Part IV of this Act shall have effect as if section 76 (2) were omitted.

(2) The following provision shall have effect for the purposes of Case III of Schedule D, notwithstanding anything to the contrary in section 76 or 77:

The tax in respect of income arising from possessions in Great Britain or Northern Ireland, other than stocks, shares, or rents, shall be computed either on the full amount thereof arising in the year preceding the year of assessment or on the full amount thereof on an average of such period as the case may require and as may be directed by the Special Commissioners, so that according to the nature of the income the tax may be computed on the same basis as that on which it would have been computed if the income had arisen in the State, and subject in either case to a deduction on account of any annual interest or any annuity or other annual payment payable out of the income to a person not resident in the State and the provisions of this Act (including those relating to the delivery of statements) shall apply accordingly; and the person chargeable and assessable shall be entitled to the same allowances, deductions, and reliefs as if the income had arisen in the State:

Provided that, in the case of lands, tenements, or hereditaments in Great Britain or Northern Ireland in the occupation of a person resident in the State which, had they been situated in the State, would have been chargeable to tax according to section 10 in respect of the property therein and the occupation thereof on an annual value estimated otherwise than in relation to profits, tax shall be charged under this provision and the income arising therefrom shall be taken to be an amount (subject to deduction as aforesaid) determined as follows, that is to say:—

(a) where the tax would in the circumstances aforesaid have been chargeable under Schedule A, the amount shall be taken to be the annual value as reduced for the purposes of collection of the lands, tenements, or hereditaments, as ascertained for the year of assessment for the purposes of the charge to income tax under Schedule A in Great Britain or Northern Ireland, as the case may be, and

(b) where the tax in the circumstances aforesaid would have been chargeable under Schedule B, the amount shall be taken to be the assessable value of the lands, tenements, or hereditaments, as ascertained for the year of assessment for the purposes of the charge to income tax under Schedule B in Great Britain or Northern Ireland, as the case may be.

In this paragraph “rents” includes any payment in the nature of a royalty and any annual or periodical payment in the nature of a rent derived from any lands, tenements or hereditaments, including lands, tenements and hereditaments to which section 56 would apply or have applied if such lands, tenements and hereditaments were situate in the State.

(3) Notwithstanding anything contained in section 65, in estimating the amount of annual profits or gains arising or accruing from any trade or profession, a deduction shall be allowed on account of lands, tenements, hereditaments, or other premises situate in Great Britain or Northern Ireland and used in whole or in part for the purpose of that trade or profession of an amount equal to the amount charged to tax under Case III of Schedule D by virtue of subparagraph (2) in respect of the income arising from such lands, tenements, hereditaments or other premises or the part so used.

2. The definition of “foreign life assurance fund” in section 1 shall, for the purposes of this Part, be construed as if, after “State”, in each place where it occurs, there were inserted “, Northern Ireland and Great Britain”.

3.—(1) Any claim for exemption from income tax or sur-tax on the ground that the claimant is resident in Great Britain or Northern Ireland and is not resident in the State shall be made to the Revenue Commissioners in such form as they may prescribe, and the said Commissioners shall on proof of the facts to their satisfaction allow the claim accordingly:

Provided that a claimant shall not be entitled to the exemption in respect of any income the tax on which he is entitled to charge against any other person, or to deduct, retain or satisfy out of any payment which he is liable to make to any other person.

(2) Any person who is aggrieved by the decision of the Revenue Commissioners on a claim made by him as aforesaid, may, by notice in writing to that effect given to the Revenue Commissioners within twenty-one days from the date on which notice of the decision is given to him, make an application to have his claim heard and determined by the Special Commissioners.

(3) Where any such application as aforesaid is made, the Special Commissioners shall hear and determine the claim in like manner as an appeal made to them against an assessment, and all the provisions of this Act relating to such an appeal (including the provisions relating to the rehearing of an appeal and to the statement of a case for the opinion of the High Court on a point of law) shall apply accordingly with any necessary modifications.

4.—(1) Notice of any claim for relief under Part II of this Schedule, together with particulars of the claim, shall be given in writing to the inspector, and, where an objection is made to the claim by the inspector, the Special Commissioners shall hear and determine the claim in like manner as in the case of an appeal to them against an assessment under Schedule D, and the provisions of this Act relating to such an appeal (including the provisions relating to the statement of a case for the opinion of the High Court on a point of law) shall apply accordingly with any necessary modifications.

(2) The Special Commissioners in determining a claim under Part II of this Schedule, shall have power to determine the rate at which relief is to be given and the amount of the relief to be given, and all questions whatsoever incidental to the determination of the matters as aforesaid.

5. In the case of any person entitled for any year to claim relief from double taxation under Article 2 of the Agreement made 25th April, 1928, which is set out in Part I of this Schedule (which deals with relief from double taxation in the case of a person who is resident both in Great Britain or Northern Ireland and in the State) tax for that year in respect of income arising from securities, stocks, shares or rents in Great Britain or Northern Ireland shall be computed on the full amount thereof arising in the year of assessment:

Provided however that tax in respect of interest arising from any security issued under the War Loan Acts, 1914 to 1917, or any Act of the United Kingdom Parliament amending these Acts where such interest is paid without deduction of British tax shall be computed in accordance with the provisions of this Act applicable to Case III of Schedule D and notwithstanding anything contained in section 75 income from any such security may be deemed to issue from a separate source.
