Income Tax Frequently Asked Questions

  • I've just arrived in Guernsey, what do I do?

    • Contact us
      • You can register with us by using the online form available by following this link or you can ask your employer to register with you.  The registration process is straightforward and once we have received the completed form we will send you an income tax reference number and a coding notice once you have secured a job.
    • Available guides
  • My circumstances have changed, what do I do?

    • I have just got married, what do I need to do?
      • You will need to tell us that you have married and we will require the name of your spouse and the date of your marriage.  Separate tax returns must be completed for the year you marry and an assessment will be issued to each of you individually.  The tax returns that are submitted in the years following will be made by the husband in an opposite-sex marriage, or the eldest spouse in a same-sex marriage, and must include income from both spouses.  Future assessments will be issued and made in the name of the husband or the eldest spouse.
    • Can I be assessed separately?
      • Either spouse can, request to be assessed separately, but this request must be received in writing, by 31 March in the year following your marriage or by 31 March in the year you wish it to commence.  If you are assessed separately, you will each complete your own tax return and your tax affairs will be kept separate.
    • I have separated/divorced, do I need to tell you?
      • You will need to contact us, in writing, to confirm the date that you separated.  Ideally this should be signed by both of you.  A new coding notice will be issued to reflect your change in circumstances and your income tax affairs will be kept separate from this date. 
    • I have had a baby, do you need to know?
      • No, having a child does not affect your income tax unless you are a single person then it is worth letting us know that your circumstances have changed and we can update your records.
    • I have given up work, how does this affect my income tax?
      • If you have given up work there is no necessity to contact us unless you are in receipt of income that does not have tax deducted at source.
    • I have changed my job, do you need to know?
      • Yes, If you have changed your job you can request a new coding notice by following this link
    • I have been made redundant from my job, do I need to pay tax on my redundancy pay?
      • It is best to contact us and provide a copy of the redundancy letter and details of the redundancy package you have been offered from your employer, as each case is dealt with individually and it would depend on the reasons for the redundancy and how much is received. Further information is available at Statement of Practice E11 (located in the October 2014 Statements of Practice booklet via "Practitioners and technical information" and "Statements of Practice (Including Interpretations of Law) & Extra Statutory Concessions" drop-down options) if a payment is treated as a termination payment for Guernsey income tax purposes.
    • I am leaving Guernsey, what do I need to do?
      • If you are leaving Guernsey you will need to complete a "pdf icon Leaving Guernsey [240kb]" checklist. You will need to ensure you have a forwarding address, a copy of your final payslip attached, and are able to provide all other necessary information prior to your departure from Guernsey.
    • I am buying a house, how can I claim relief for my mortgage?
      • If you are buying a house you will need to complete a "pdf icon Buying Property [180kb]" checklist.  If you have taken out a mortgage on your new property you may be able to claim tax relief on the interest paid, therefore it is important that the checklist has been completed and submitted to us.  A guide on claiming allowances and the relief available to you on the mortgage interest paid is available by following this link under the 'Rates and Allowances' section.
    • I am retired, do I need to pay Tax on my pension?
  • Civil Partnerships and Same-Sex Marriage

    • On 21 September 2016, the States approved the draft Projet entitled The Same-Sex Marriage (Guernsey) Law, 2016.  From 1 January 2017, for income tax purposes, civil partnerships and same-sex marriages will be legally recognised in Guernsey. 
    • People who have entered into a same-sex marriage or a civil partnership will be treated in the same way. Both couples will be assessed jointly (unless a request is made to be separately assessed) and they will be entitled to a married persons allowance (for more information follow this link and see Summary of Allowances under "Rates and Allowances").  The responsibility for dealing with the tax affairs of the couple will be with the elder partner.
    • Below are some frequently asked questions which we hope will help you to understand this process, but if you are unsure, would like more information, or wish to speak with a tax assessor, please contact us on 01481 740123 or 01481 724711, ensuring you have your tax reference number to hand.
    • What is meant by a "civil partnership"?
      • A civil partnership is a relationship between two people of the same-sex, formed when they register as civil partners of each other.  This should be registered either under the UK Civil Partnership Act 2004, the Civil Partnership (Jersey) Law 2012, or an equivalent law in another territory. The relationship will end only on death, dissolution or annulment.
    • Do we need to tell you when we enter into a same sex marriage or civil partnership?
      • If you have entered into a same sex-marriage or civil partnership prior to 1 January 2017 you need to tell us as soon as possible, as you will be treated as married for 2017.  You will need to submit a joint return for 2017, unless you ask for separate assessments.  If you wish to be separately assessed for 2017, you have until 31 March 2017 to make the election.
      • If you enter into a same-sex marriage or civil partnership after 1 January 2017 you will need to tell us and will need to submit separate returns for the year of marriage and a joint return for the year following your marriage.  You can elect to be separately assessed; if you do, you will each need to complete an income tax return each year.  If your marriage takes place in 2017, a request for separate assessments can be made at any time after the ceremony, as long as this is done before 31 March the following year.
      • Either partner may elect to be separately assessed but it may only be withdrawn in writing, by whoever made the original request.
    • Do we have to submit a joint income tax return?
      • Yes, unless you request to be assessed separately, but you will need to do this in writing before 31 March.
    • Can we choose which one of us will be responsible for the completion and submission of our annual income tax returns?
      • No.  The eldest partner will automatically become responsible for both of your income tax affairs, unless a request for separate assessments is made.  Requests must be made in writing by 31 March.
    • Can we be separately assessed?
      • Yes.  You can request separate assessments as long as the request is received in writing and made in the year of marriage, or before 31 March in any given year.
    • Are we able to transfer allowances between us in the coding notice?
      • Yes, you can transfer allowances between you if you have a joint assessment.
      • Coding notices will be issued to you both with allowances divided between you, but if you want them split in a different way you will need to complete a 'Division of Allowances form' (available on our website under "Other tax forms") and revised coding notices will be sent to your employers.
    • Will you recognise a civil partnership that took place prior to 1 January 2017?
      • Yes, but we are only able to change the way your tax affairs are dealt with from 1 January 2017.  No change will be made to the way you were treated for income tax purposes for earlier years, but your affairs will be dealt with jointly with effect from the calendar year 2017, unless a request for separate assessments is made.
    • What do we do if we separate?
      • If you separate you need to tell us so that we can bring your income tax affairs up to date.  You will be treated as single from the date of your separation.  The date of separation will need to be agreed by you both and confirmed in writing to us.
      • The date of separation should be from when you no longer live as a couple rather than when your civil partnership or marriage is dissolved.
    • We are an unmarried same-sex co-habiting couple, can we claim any additional allowances?
      • From 1 January 2017, a same-sex co-habiting couple may relinquish unused personal allowances between themselves if they co-habit for the full calendar year and are in receipt of Guernsey Family Allowance. For more information see our pdf icon Guide to claiming allowances and reliefs [289kb] . 
  • I've received my statement and assessment but I don't understand them, where can I get some guidance?

    • The statement will show you the tax that has been credited from the contributions made through your employer and will be grouped into years. The easiest way to understand your statement is to look at each year in isolation as this will show you the tax you have paid and the tax your assessment has calculated.  If there is a difference between the two this will result in either tax owing or a repayment.
  • My statement shows I'm in credit, what does this mean?

    • This could be for a number of reasons, mostly this will be because you have paid more tax through the contributions made by your employer than you need to pay once all of your income has been added together.  If a repayment is due it will be sent to you within 4 weeks of receiving your statement.
  • Why does my statement say I owe tax?

    • Your coding notice included too many allowances
      • Sometimes your coding notice will include allowances, such as mortgage interest, which are estimated. When a figure is included in your coding notice it is for the full calendar year and are based on the figures provided either when you purchase the property or from the latest tax return submitted to us.  Therefore, it can sometimes be difficult to accurately predict what interest you are likely to pay for the coming year, unless you have a fixed rate mortgage.
    • You are receiving UK, Jersey or overseas old age pension
      • Another example of an underpayment of tax could be when you begin to receive an old age pension from the UK, Jersey or overseas. As these pensions do not have tax deducted before it is paid to you we are not aware of the rate of pension you will receive, therefore, it is difficult to put in place measures to try and avoid a bill.  We are sometimes only aware that you are in receipt of a pension when you disclose it on your tax return in the following calendar year.
    • You had an Estimated Assessment
      • Estimated assessments are sometimes issued to collect additional tax on income that does not have tax deducted before it is paid to you.  An example of this is if you are in business.  If you receive an assessment which includes an estimated business profit, for example, you will pay the tax due based on those figures, however, when your final accounts are prepared the amount of taxable business profit may differ.  This may result in additional tax being payable on your account.
    • You changed jobs part way through the year
      • If you change jobs part way through the year you may still get paid from your old employer after you have left, thereby receiving wages from both your old employer and your new employer in the same month.  The allowances that are included in your coding notice will have been used by both employers which will result in an underpayment of tax.
    • How do I pay my tax, what options do I have?
      • If you are employed your employer will take tax from your wages each week or month and send it into us each quarter which is credited to your account.
      • If you have tax to pay in addition to the deductions made by your employer, for example if you have a pension or some investment income that does not have tax deducted before it is paid to you, then you can make a payment online by following this link, you will need your tax reference number to pay online (your reference can be found on all correspondences from the Revenue Service).
  • Interim assessment suspension process

    • What is an interim assessment?
      • An interim assessment is issued to collect tax for the current year if you have income that does not have tax deducted at source, e.g. business income, rental income, bank interest, old age pensions, etc.
      • An interim assessment is based either on figures provided by you, for the previous year, or they have been estimated.
    • I don't agree with my interim assessment, what do I do?
      • You can't appeal against an interim or an interim (estimated) assessment although you can request that tax is suspended if you think the assessment is too high.
    • How do I ask for tax to be suspended?
      • You can request a suspension of tax using our online form
    • Will I be told if you agree to my request?
      • No, we will contact you if your request cannot be accepted with the reasons why. If you are unhappy with this decision you can appeal.
    • Will I receive a revised assessment?
      • No, the interim assessment will only be revised when your completed income tax return for the relevant calendar year has been processed.
  • Appealing against a final assessment if I have submitted a tax return

    • An appeal allows you to notify the Director that you don't agree with your final assessment and the reasons why.
    • You can't appeal against an Interim or an Interim (Estimated) assessment although you can request tax is suspended (see FAQ above).
    • When should I appeal?
      • A final assessment includes figures you have submitted on your income tax return, or the amounts that have been given to us by a third party, such as your employer or pension provider. If you disagree with the figures in the assessment you should send in an appeal.
    • How do I appeal?
      • An appeal must be submitted, in writing, within 30 days of the date on the assessment. If possible you should use the Appeal Form pdf icon Form 690(a) [154kb] which will enable us to process your appeal.  See pdf icon Appeals form guidance [220kb] for some help on how to complete the form.
      • If you write in or email please make sure it is clearly marked "Appeal" and that you include the reasons why you disagree with the figures in the assessment.  You will also need to tell us how much you think you need to pay.
    • Do I need to make a payment if I have appealed?
      • Yes, you will need to make a payment based on your calculations as outlined in your appeal (e.g. form/letter/email).  This amount should be paid by the date shown on your statement. We will not pursue the remaining balance while this appeal is ongoing.
    • Will I know if you have received my appeal?
      • If you provide your email address your appeal will be confirmed.
      • We will also contact you if your appeal cannot be accepted with the reasons why.
    • What happens next?
      • Either a revised assessment will be issued or we will contact you explaining the reasons why your appeal cannot be accepted. If you are unhappy with this decision you may ask for the appeal to be heard before the Guernsey Tax Tribunal, which is an independent appeal body set up to hear income tax appeals that can't be resolved.
  • How is my tax calculated?

    • In simple terms, when you complete your annual income tax return the figures you declare are offset against your personal allowances and the balance is taxed at 20%.
    • Details of the basic personal allowances are available here under "Rates and Allowances". For example, if you are a single person, you can earn £9,675 in 2016 before you pay tax.
  • How does my employer know what tax to take from my wages?

    • At the beginning of each year, or when you commence employment, your employer will be sent a coding notice which will tell them how much allowance they should deduct from your gross wages, they then tax the balance at 20%.  
  • I have received a sum of money from the Employment & Discrimination Tribunal, is it taxable?

    • Yes, an award made for unfair dismissal, or as a result of the termination of your employment is subject to tax. The first £30,000 of the total payment received from the termination of your employment is exempt from tax.
  • Why do I have to pay tax?

    • Everybody has to pay income tax as it helps to support and develop the infrastructure of our island, without which the essential services that we all use would not function.
  • I am recently bereaved, what do I need to do?

  • Why am I receiving less than the full allowances?

    • What does 'pro-rating of personal allowances' mean?
      • If you permanently arrive or depart from Guernsey your personal tax allowances will be based on the number of weeks you spent in Guernsey in the year in which your arrive and the year in which you permanently depart.
    • What does 'permanently depart' mean?
      • A permanent departure from Guernsey means that you have made a decision to leave and set up home elsewhere.
    • What if I return to Guernsey in the same calendar year?
      • If you come back to Guernsey in the same year as you left you will not be treated as if you left permanently.
    • What if I leave Guernsey and return in the following year on a regular basis?
      • If you leave Guernsey and come back each year you will be treated as though your departure from Guernsey was permanent.
    • What if I take a long holiday abroad but keep my home in Guernsey?
      • if you take a long holiday each year but return to your home in Guernsey you will be treated as though your departure from Guernsey is not permanent
  • Single Premium Life Assurance Bond ("SPLAB")

    • What is a SPLAB?
      • Sometimes referred to as a life assurance wrapper, a SPLAB is a bond with life assurance attached, typically used as an investment. An investor pays a cash lump sum into the investment bond, which buys units within available funds. Similar to a life assurance policy, the investment bond pays out on the death of the life assured or lives assured, in accordance with the terms of the policy.
    • If I take money from the SPLAB, is it taxable?
      • If money is taken from the bond by either a partial or full surrender within the first 10 years of the original investment being made, then any growth on the underlying fund(s) which were sold to make the withdrawal would be assessable to income tax in the calendar year that the money was taken out. If a withdrawal is made within the first 10 years of the original investment, then the growth on all further withdrawals would also be taxable. Any increments or top-ups to the investment bond would be considered a new investment and the 10-year rule would apply to each investment.
      • If you don't make withdrawals from your investment bond and hold it for a minimum period of 10 years, then any partial surrenders or full surrenders after the 10 years would not be taxable. The 10 year rule is laid out in the Statement of Practice M18, Life Assurance Policies (including Single Premium Life Assurance Bonds) issued by the Director, available to view here under "Statements of Practice".
      • The 10 year exemption does not apply to second hand endowment policies purchased. Any growth on these policies will be taxed in full.
      • If the investment bond pays out on the death of the last life assured, the amount paid out is not assessable to income tax.
    • If I do take money from the bond in the first 10 years, what do I need to provide?
      • A copy of the full unit history transaction statement of the investment bond is needed to see if there is any taxable growth on the underlying fund(s) which were sold to make the withdrawal. This should be provided from the date of the original investment to 31 December for each calendar year until the investment bond has been fully surrendered. Please note, this is only required if a withdrawal, partial surrender or full surrender has been made.
    • How do I obtain a "full transaction unit history" statement?
      • You can get a full transaction unit history statement direct from the investment bond provider, or your independent financial adviser (IFA) should also be able to help you.
    • Why do I need to provide this information?
      • Most SPLABS are based on units being held. These units are sold when you make a withdrawal from your investment bond. An element of the withdrawal is considered to be your original investment (capital) which isn't taxable, so we need to see if there is any growth which would be assessable to income tax. This can only be accurately calculated when the amount of units are known for each fund, together with the original cost price, the cash withdrawn and the price and number of the units sold to make the withdrawal.
    • What if I make a loss on my withdrawals?
      • You could make a loss if the value of the units sold, to take money from the SPLAB are less than what you paid for them when the investment was made. If you make a loss it can be set-off against any growth on the surrender of units in another investment bond in the same year, or it may be carried forward to set-off against any growth arising from partial or complete surrender of the same investment bond in later years.
    • Are the product charges of an investment bond provider or early exit penalties an allowable dedution to set-off against any growth?
      • No.  Charges within the underlying fund(s) however, are allowable and will be taken into account when calculating the gain or loss.
    • What if I switch between funds within a bond?
      • Fund switches within an investment bond would not be treated as partial surrenders and would not give rise to a tax charge. However, the surrender or partial surrender to invest into another bond/investment within the 10 year period would be treated as a surrender/partial surrender and any growth is taxable.
    • Are there any amounts taxable on the death of the policyholder?
      • No, any death benefit paid is not taxable.
    • What if the investment bond is not unitised?
      • If the policy does not consist of units, then you will need to provide a statement showing the amount withdrawn together with the market value of the remaining investment after the partial surrender.
    • Can you give me an example of how the taxable growth, or loss, is calculated?
      • Example 1 shows a taxable growth: 
        Original investment£40,000
        Date of original investment12 March 2017
        Number of units purchased in underlying fund25188.453
        Original cost of each unit (£40,000 ÷ 25188.453)£1.588
        A partial withdrawal of £2,400 was made on 12 September 2017, 1427.081 units sold 
        Units sold 1427.081£2,400.00
        Original cost (1427.081 x 1.588)£2,266.20 (capital not taxable)
        Taxable growth£   133.80
        Example 2 shows a loss: 
        Original investment£40,000
        Date of original investment7 January 2017
        Number of units purchased in underlying fund22188.453
        Original cost of each unit (£40,000 ÷ 22188.453)£1.803
        A partial withdrawal of £2,400 was made on 7 July 2017, 1427.081 units sold 
        Units sold 1427.081£2,400.00
        Original cost (1427.081 x 1.803)£2,573.03
        Loss£   173.03


    • The above FAQ is based upon the Statements of Practice M18 and M18A, as published by the Director.
  • Undercharging/overcharging mortgages by banks

    • My bank has advised me that I was undercharged on my mortgage, what should I do?
      • If the bank writes off the shortfall then you do not need to contact us or include any information regarding this on your tax return.
      • If the bank is expecting you to pay the shortfall, then you should declare any mortgage interest payments made during the year on your tax return in Section J. You should not declare any shortfall payments made in respect of the capital.
    • My bank has advised me that I was overcharged on my mortgage, what should I do?
      • You should declare any interest that was overpaid and details of the amounts returned to you on your tax return in Section D, as the interest is taxable in the year it is received, or the year it is paid against the mortgage balance. This is because you will previously have been granted mortgage interest relief on the amount of interest paid.
      • Any capital repayment that is repaid to you, or paid against your mortgage is not taxable for Guernsey income tax purposes.
    • My bank has paid me compensatory interest due to errors with my mortgage, what should I do?
      • You should provide details of any compensatory interest on your tax return in Section D as it is taxable in the year it is received in cash form, or the year it is paid against the mortgage balance.
  • I have a complaint, how do I tell you about it?
