Income tax: the scope of income tax, residence and overseas aspects: formula sheet
Key formulas
- Computation flow
- Total income − reliefs = net income; net income − personal allowance = taxable income
- Show non-savings, savings and dividend columns separately.
- Order of taxation
- Non-savings first, then savings, then dividends
- The personal allowance is also set against income in this order.
- Normal rates (non-savings and savings)
- Basic £1–£37,700: 20%. Higher £37,701–£125,140: 40%. Additional over £125,140: 45%
- Bands apply to taxable income, after the personal allowance.
- Dividend rates
- Basic 8.75%. Higher 33.75%. Additional 39.35%
- Use the band in which each slice of dividend falls.
- Savings nil rate band
- Basic rate taxpayer £1,000. Higher rate taxpayer £500
- Based on the rate band the taxpayer's taxable income reaches. An additional rate taxpayer gets no savings nil rate band.
- Dividend nil rate band
- £500
- Available to all taxpayers. The £500 is taxed at 0% but uses up band.
- Starting rate for savings
- 0% on savings income falling within the first £5,000 of taxable income
- Non-savings taxable income uses up the £5,000 first. The starting rate is lost once non-savings taxable income reaches £5,000.
- Personal allowance
- £12,570
- Transferable amount £1,260 where the marriage allowance rules apply.
- Personal allowance restriction
- Reduction = (adjusted net income − £100,000) ÷ 2
- The allowance is nil when adjusted net income is £125,140 or more. Adjusted net income is net income less the gross amount of gift aid donations and personal pension contributions.
- Cap on income tax reliefs
- Reliefs capped at the higher of £50,000 or 25% of income
- Applies to specified reliefs only, such as certain trading loss reliefs against general income. Charitable giving and pension relief are not within the cap.
- Extending the basic rate band
- Basic rate band = £37,700 + gross gift aid donations + gross personal pension contributions
- Gross means the net payment × 100/80. Only the bands move, not the taxable income.
- Sufficient ties table: previously resident
- Under 16 days: not resident | 16-45 days: resident if 4 ties | 46-90: 3 ties | 91-120: 2 ties | 121-182: 1 tie | 183 or more: resident
- This is given in the tax tables. Check the column for previously resident, then match days to ties.
- Sufficient ties table: not previously resident
- Under 16 days: not resident | 16-45 days: not resident | 46-90: resident if 4 ties | 91-120: 3 ties | 121-182: 2 ties | 183 or more: resident
- Use this column for someone not resident in the UK in any of the previous three tax years.
- Order of the test
- Automatic overseas tests → automatic UK tests → sufficient ties test
- Stop at the first conclusive test. Do not go to ties if an automatic test decides the case.
- Automatic overseas test (days)
- Fewer than 16 days in the UK, or fewer than 46 days if not resident in any of the previous three years
- Either leads to not resident. Other overseas tests relate to full-time work overseas and to leavers working abroad. Check the facts given.
- Automatic UK test (days)
- 183 or more days in the UK in the tax year
- Leads to UK resident. Other UK tests cover a UK home and full-time UK work. Check the conditions in the scenario.
- UK ties
- Family, accommodation, work, 90-day, country
- The country tie applies only to those previously resident. Define each tie against the facts.
- Statutory residence test: days in UK (previously resident)
- Under 16 days: automatically not resident. 16–45: resident with 4+ ties. 46–90: 3+ ties. 91–120: 2+ ties. 121–182: 1+ tie. 183+: automatically resident
- From the tax table given in the exam. Use it first, because residence comes before domicile or LTR.
- Statutory residence test: days in UK (not previously resident)
- Under 46 days: automatically not resident. 46–90: resident with 4 ties. 91–120: 3+ ties. 121–182: 2+ ties. 183+: automatically resident
- Fewer ties are needed for someone previously resident, so check which column applies.
- Long-term UK resident (LTR) for IHT
- UK resident in at least 10 of the 20 tax years immediately before the relevant tax year
- Rule stated in outline. An LTR has worldwide assets within IHT. Use the exact test given in the question or examinable documents.
- Tail after leaving the UK
- 10–13 years' residence: 3 years. Then +1 year for each extra year of residence. Maximum 10 years
- During the tail the leaver is still treated as an LTR for IHT.
- Older deemed domicile tests (IHT)
- UK domiciled in the previous 3 years, or UK resident in 15 of the previous 20 tax years
- Know these as background, since questions may refer to them. Do not apply them if the question uses the residence-based rules.
- IHT rates and bands
- Nil rate band £325,000. Residence nil rate band £175,000. Lifetime rate 20%. Death rate 40%
- The residence nil rate band relates to a home passed to direct descendants. Use it only where the question suggests it applies.
- Taper relief on death within 7 years
- 3–4 years: 20% reduction. 4–5: 40%. 5–6: 60%. 6–7: 80%
- It reduces the tax, not the value of the gift. Under 3 years: no reduction.
- Residence basis of charge
- UK resident: worldwide income and gains (arising basis). Non-resident: UK-source income only
- Decide residence first using the statutory residence test and the day and ties table given in the exam.
- FIG regime conditions
- Non-resident for the previous 10 consecutive tax years, then claim in each of the first 4 tax years of UK residence
- Foreign income and gains are then outside UK tax for that year. It is an annual claim, so you can choose year by year.
- Cost of claiming FIG
- Claim made = no personal allowance and no CGT annual exempt amount (£3,000) for that year
- Compare tax with and without the claim. Do not assume claiming is always better.
- Income tax rates (2025/26)
- Non-savings: 20% to £37,700, 40% to £125,140, 45% above. Dividends: 8.75%, 33.75%, 39.35%. Dividend nil rate band £500
- Savings nil rate band is £1,000 for basic rate and £500 for higher rate taxpayers. Additional rate taxpayers get none.
- CGT rates
- 18% lower rate, 24% higher rate, annual exempt amount £3,000
- For a resident not claiming FIG, foreign gains are taxed in the year of disposal.
- Double tax relief (unilateral or treaty)
- Credit = lower of (foreign tax suffered, UK tax on that foreign income)
- Work out UK tax on each source of foreign income separately. Foreign tax above the treaty rate is not creditable.
- Credit relief limit
- Credit = lower of (foreign tax suffered; UK tax on that foreign income)
- Work it out separately for each source of income or gain. Excess foreign tax is not carried forward or across to another source.
- UK tax on the foreign income
- UK tax on foreign income = total UK tax with the income − total UK tax without it
- Include the foreign income gross. It is the top slice within its income type, so it normally takes the marginal rate.
- Net UK tax payable
- UK tax liability − DTR credit
- Credit relief cannot create a repayment of UK tax.
- Personal allowance
- £12,570, reduced by £1 for every £2 of adjusted net income above £100,000
- It is nil when adjusted net income is £125,140 or more. Non-residents get it only if they are in a qualifying category.
- Income tax rates
- Basic band £37,700 at 20%; higher rate to £125,140 at 40%; additional rate 45%
- Normal rates are used for the non-savings income in the examples. Dividend and savings rates differ.
- CGT rates
- 18% in the lower band, 24% in the higher band; annual exempt amount £3,000
- The same lower-of rule applies to foreign tax on gains.
- UK resident CGT scope
- UK resident individual: CGT on gains from worldwide assets
- Residence in the year of disposal is the test. Remittance basis points are outside this page.
- Non-resident CGT scope
- Non-resident: generally no UK CGT, except UK land and property and certain other UK-linked disposals
- Always state the asset type. UK residential property is the usual exam asset.
- CGT rates
- Lower rate 18%, higher rate 24%, annual exempt amount £3,000
- Rates apply to gains after the annual exempt amount. The lower rate applies only where basic rate band remains after taxable income.
- Business asset disposal relief
- Rate 14%, lifetime limit £1,000,000
- Investors' relief has the same limit and rate. Check the qualifying conditions in the question.
- Temporary non-residence
- UK resident for at least 4 of the 7 tax years before departure + period of non-residence of 5 years or less = gains on assets owned at departure and disposed of during the absence are taxed in the year of return
- The asset must have been acquired before departure. These tests are not confirmed by the tax tables supplied, so verify them against the ATX-UK article on international aspects of personal taxation.
- IHT domicile scope
- UK domiciled or deemed domiciled: worldwide assets. Neither: UK assets only
- Overseas assets of a person who is neither are excluded property.
- IHT nil rate bands and rates
- NRB £325,000; RNRB £175,000; lifetime rate 20%; death rate 40%
- Tax is on the excess over the nil rate band. Take the figures from the tax tables.
- Taper relief
- 3-4 years 20%; 4-5 years 40%; 5-6 years 60%; 6-7 years 80% reduction
- The reduction is applied to the tax, not the value of the gift. It only helps if tax is due on the gift.
- Statutory residence test: automatic outcomes
- Under 16 days = automatically not resident; 183 days or more = automatically resident
- These apply to both previously resident and not previously resident individuals. Use the table in the exam for the middle bands.
- Not previously resident: ties needed
- 16-45 days: automatically not resident; 46-90: 4 ties; 91-120: 3 or more ties; 121-182: 2 or more ties
- Resident if the ties shown are met. Check the 'previously resident' column separately, as the tie numbers are lower.
- Previously resident: ties needed
- 16-45 days: 4 or more ties; 46-90: 3 or more; 91-120: 2 or more; 121-182: 1 or more
- Same table, other column.
- Workday apportionment
- UK taxable earnings = total earnings × UK working days ÷ total working days
- Use this when the question gives no other basis. State that you have apportioned on a working-day basis. Round to the nearest £.
- Pension annual allowance
- £60,000 standard (2023/24 to 2025/26); minimum allowance £10,000
- Threshold income limit £200,000; adjusted income limit £260,000. The tax-relieved maximum with no earnings is £3,600.
- Tapered annual allowance
- Allowance = £60,000 - (adjusted income - £260,000) ÷ 2, not below £10,000
- Applies only where threshold income exceeds £200,000 and adjusted income exceeds £260,000.
- Class 1 NIC rates
- Employee: 8% on £12,571-£50,270, 2% above. Employer: 15% above £5,000
- Use only where the question makes the employment subject to UK Class 1 NIC.
Quick revision
- Fewer than 16 days in the UK means automatically not resident for everyone.
- 183 or more days in the UK means automatically resident.
- For the sufficient ties test, previously resident people need fewer ties than those not previously resident.
- With 16 to 45 days, a person not previously resident is automatically not resident.
- With 121 to 182 days, a previously resident person is resident with one tie or more.
- Check the automatic tests before you use the ties table.
- Residence and domicile are separate tests; do not mix them up.
- Income tax bands: basic £1 to £37,700 at 20%, higher up to £125,140 at 40%, additional above that at 45%.
- Dividend rates are 8.75%, 33.75% and 39.35%, with a £500 dividend nil rate band.
- Inheritance tax: nil rate band £325,000, lifetime rate 20%, death rate 40%.
- Capital gains tax rates are 18% and 24%, with an annual exempt amount of £3,000.
- Always state your conclusion and give reasons, not just the figures.
Common mistakes
- Setting the personal allowance against dividends or savings first. Fix: Always deduct the allowance from non-savings income first, then savings, then dividends.
- Using net income instead of adjusted net income to test the personal allowance restriction. Fix: Deduct gross gift aid and gross personal pension contributions from net income before you test against £100,000.
- Going straight to the ties table. Fix: Always check the automatic overseas and UK tests first. Write a short line for each.
- Using the wrong column for previous residence. Fix: Underline previous residence in the scenario and pick the column before you read the days band.
- Treating residence and domicile as the same thing. Fix: Residence is tested by days and ties each year. Domicile is a permanent-home concept in law. Long-term residence is a count of years. State which one you are applying.
- Using the old 15 of 20 deemed domicile rule when the question gives residence-based facts. Fix: Read the requirement. Use the test the question and the examinable documents support, and name it in your answer.
- Taxing a UK resident only on remitted foreign income. Fix: State that the arising basis is the default for a UK resident, and use the FIG regime only for qualifying new arrivals.
- Giving the FIG regime to anyone newly resident, without checking the ten-year test. Fix: Count the earlier tax years and check they are ten consecutive years of non-residence before applying the regime.
- Deducting the foreign tax in full without comparing it with the UK tax. Fix: Always write 'lower of' and show both figures. The credit can never exceed the UK tax on that income.
- Including foreign income net of foreign tax in the UK computation. Fix: Gross it up to the amount before foreign tax. UK tax is charged on the gross income and the foreign tax is then credited.
Exam tips
- Set out the computation with three columns for non-savings, savings and dividends. Markers give marks for a clear layout even when a figure is wrong.
- Read every question for gift aid, pension contributions and loss reliefs. They change adjusted net income and the basic rate band, and they are a common source of marks.
- Use the tax tables ACCA provides. Do not rely on memory for rates and bands. Assume 2025/26 rates apply unless the question says otherwise.
- Calculations only need to be to the nearest £. Show all workings, because follow-through marks are given for correct methods.
- When asked to advise, comment on the effective 60% rate between £100,000 and £125,140. Show how a pension or gift aid payment can cut tax in that range.
- Show the order of the tests in your answer. Even a single line for each automatic test earns credit.
- State previous residence and the day count first, since the table depends on both.
- Define each tie against the scenario facts. Do not just list tie names.
