Tax Calculation Year 2019 20

Module A: Introduction & Importance

The 2019-20 tax year (6 April 2019 to 5 April 2020) introduced several important changes to the UK tax system that continue to impact taxpayers today. Understanding your tax obligations from this period remains crucial for several reasons:

• Historical Accuracy: Many individuals need to file amended returns or understand past tax liabilities
• Financial Planning: Comparing with current tax years helps identify optimization opportunities
• Legal Compliance: HMRC may investigate returns up to 20 years old in cases of suspected fraud
• Investment Decisions: Pension contributions and ISAs from this period affect long-term financial strategies

This period marked the final year before significant changes in 2020-21, including:

• Increased National Insurance thresholds
• Adjustments to Scottish income tax bands
• Changes to dividend allowances
• Modifications to capital gains tax

Note: Personal allowance begins phasing out at £100,000 (£1 less for every £2 earned above this threshold)

2. England/Wales/NI Income Tax Bands (2019-20)

Band	Taxable Income	Tax Rate
Personal Allowance	Up to £12,500	0%
Basic Rate	£12,501 to £50,000	20%
Higher Rate	£50,001 to £150,000	40%
Additional Rate	Over £150,000	45%

3. Scottish Income Tax Bands (2019-20)

Band	Taxable Income	Tax Rate
Personal Allowance	Up to £12,500	0%
Starter Rate	£12,501 to £14,549	19%
Basic Rate	£14,550 to £24,944	20%
Intermediate Rate	£24,945 to £43,430	21%
Higher Rate	£43,431 to £150,000	41%
Top Rate	Over £150,000	46%

4. National Insurance Calculations

Class 1 NI contributions for employees (2019-20 rates):

• 12% on weekly earnings between £166 and £962
• 2% on weekly earnings above £962

Class 4 NI for self-employed:

• 9% on annual profits between £8,632 and £50,000
• 2% on annual profits above £50,000

Module D: Real-World Examples

Case Study 1: London Professional (£60,000 Salary)

Scenario: Marketing manager in London with £60,000 salary, £3,000 pension contributions, standard personal allowance.

Calculation:

• Taxable Income: £60,000 – £12,500 – £3,000 = £44,500
• Income Tax: (£37,500 × 20%) + (£7,000 × 40%) = £9,100
• National Insurance: (£43,464 × 12%) + (£6,536 × 2%) = £5,422.08
• Take Home Pay: £60,000 – £9,100 – £5,422.08 = £45,477.92

Case Study 2: Scottish Teacher (£35,000 Salary)

Scenario: Secondary school teacher in Edinburgh with £35,000 salary, £2,400 pension contributions.

Calculation:

• Taxable Income: £35,000 – £12,500 – £2,400 = £20,100
• Income Tax: (£2,049 × 19%) + (£5,351 × 20%) + (£12,700 × 21%) = £3,600.59
• National Insurance: (£33,464 × 12%) + (£1,536 × 2%) = £4,067.68
• Take Home Pay: £35,000 – £3,600.59 – £4,067.68 = £27,331.73

Case Study 3: Self-Employed Consultant (£90,000 Profit)

Scenario: IT consultant with £90,000 net profit, £10,000 pension contributions.

Calculation:

• Taxable Income: £90,000 – £12,500 – £10,000 = £67,500
• Income Tax: (£37,500 × 20%) + (£30,000 × 40%) = £18,500
• National Insurance: (£41,368 × 9%) + (£48,632 × 2%) = £4,999.76
• Take Home Pay: £90,000 – £18,500 – £4,999.76 = £66,500.24

Module F: Expert Tips

Maximizing Your 2019-20 Tax Efficiency

1. Pension Contributions: The annual allowance was £40,000. Contributions reduce taxable income and can restore personal allowance for high earners.
2. Charitable Donations: Gift Aid donations extend the basic rate band, potentially saving 20-45% tax on the donation amount.
3. Marriage Allowance: Transfer £1,250 of personal allowance between spouses if one earns under £12,500.
4. Capital Gains: The 2019-20 allowance was £12,000. Time asset sales to utilize this annual exemption.
5. Dividend Planning: The £2,000 dividend allowance meant basic rate taxpayers paid 7.5% on dividends above this.

Common Mistakes to Avoid

• Forgetting to claim work-from-home expenses (£6/week without receipts)
• Not declaring side income (HMRC’s Connect system flags discrepancies)
• Missing the 31 January 2021 filing deadline (automatic £100 penalty)
• Incorrectly calculating student loan repayments (Plan 1 threshold was £18,935)
• Overlooking blind person’s allowance (£2,450 additional allowance)

Special Considerations

For complex situations, consider:

• Non-doms: Remittance basis rules changed in 2017 but still affect 2019-20 returns
• Property Income: Mortgage interest relief was restricted to 20% tax credit
• IR35 Rules: Off-payroll working rules began affecting private sector in April 2020 but may impact 2019-20 contracts
• State Pension: The new state pension was £168.60 per week in 2019-20

Module G: Interactive FAQ

What were the key tax changes between 2018-19 and 2019-20?

The main changes included:

• Personal allowance increased from £11,850 to £12,500
• Higher rate threshold rose from £46,350 to £50,000
• Scottish starter rate reduced from 19% to 19% (no change) but intermediate band expanded
• National Insurance thresholds increased slightly
• Dividend allowance remained at £2,000
• Capital gains tax allowance increased from £11,700 to £12,000

These changes generally reduced tax burdens for most taxpayers compared to 2018-19.

How does the calculator handle Scottish tax bands differently?

The calculator applies these key differences for Scottish taxpayers:

1. Uses 5 tax bands instead of 3 (19%, 20%, 21%, 41%, 46%)
2. Applies the starter rate (19%) on income between £12,501-£14,549
3. Uses a 21% intermediate rate for income £24,945-£43,430
4. Applies higher rates (41% and 46%) at lower thresholds than rUK
5. Maintains the same £12,500 personal allowance

This typically results in slightly lower taxes for earners under £26,000 but higher taxes for those earning over £26,000 compared to other UK regions.

Can I still amend my 2019-20 tax return?

Yes, but with important limitations:

• Online Returns: Can be amended until 31 January 2022 (now closed)
• Paper Returns: Must be amended by 31 October 2021 (now closed)
• Current Options:
  • Write to HMRC explaining the changes needed
  • Provide supporting documentation
  • HMRC may accept late amendments if you have a “reasonable excuse”
• Time Limits: HMRC can normally go back 4 years (until 5 April 2024 for 2019-20) but up to 20 years for suspected fraud

For complex amendments, consider using HMRC’s official correction service.

How did student loan repayments work in 2019-20?

The calculator doesn’t include student loans, but here’s how they worked:

Plan Type	Threshold (Annual)	Repayment Rate	Interest Rate
Plan 1	£18,935	9%	1.75%
Plan 2	£25,725	9%	2.4% + RPI
Postgraduate	£21,000	6%	3.4% + RPI

Repayments were deducted automatically through PAYE for employees. The self-employed included repayments in their Self Assessment.

What records should I keep for 2019-20 taxes?

HMRC recommends keeping these records for at least 22 months after the tax year ends (until 31 January 2022 for 2019-20), but longer if:

• You’re self-employed (5 years)
• You own property (5 years)
• You have capital gains (5 years)

Essential documents to retain:

• P60 from your employer
• P45 if you changed jobs
• P11D for benefits in kind
• Bank statements showing interest
• Dividend vouchers
• Receipts for expenses
• Pension contribution statements
• Charitable donation receipts
• Student loan statements
