Formula & Methodology Behind the Calculator
Our 2015-16 tax calculator uses the exact rates and thresholds published by HMRC for this tax year. Here’s the detailed methodology:
Income Tax Calculation
The UK operated a progressive tax system in 2015-16 with these bands:
| Tax Band | Taxable Income | Rate (England/Wales/NI) | Rate (Scotland) |
|---|---|---|---|
| Personal Allowance | Up to £10,600 | 0% | 0% |
| Basic Rate | £10,601 to £42,385 | 20% | 10% (£10,001-£15,000) 20% (£15,001-£42,385) |
| Higher Rate | £42,386 to £150,000 | 40% | 40% |
| Additional Rate | Over £150,000 | 45% | 45% |
The calculation process:
- Subtract personal allowance (£10,600) from gross income
- Apply pension contributions (reduces taxable income)
- Calculate tax for each band based on remaining taxable income
- For Scottish taxpayers, apply the starter rate (10%) on income between £10,000-£15,000
- Add up all tax amounts for final income tax liability
National Insurance Contributions
Class 1 NICs for employees in 2015-16:
- Primary Threshold: £155/week (£8,060/year)
- Upper Earnings Limit: £815/week (£42,385/year)
- Rate: 12% on earnings between thresholds, 2% above upper limit
Student Loan Repayments
Calculated as 9% of income above the threshold:
- Plan 1: £17,335 annual threshold
- Plan 2: £21,000 annual threshold

Interactive FAQ: 2015-16 Tax Calculator
Why would I need to calculate taxes for 2015-16 now?
There are several valid reasons to calculate your 2015-16 taxes today:
- Late Tax Returns: If you didn’t file a return for this year, you’ll need accurate calculations to complete it. HMRC can go back up to 20 years for investigations in cases of suspected fraud.
- Tax Refunds: You might be due a refund if you overpaid tax, especially if you had multiple jobs or irregular income patterns.
- Financial Planning: Understanding your historical tax position helps with long-term financial planning and comparing your current tax efficiency.
- Legal Disputes: In cases of divorce or inheritance disputes, accurate historical tax calculations may be required.
- HMRC Enquiries: If HMRC is investigating your affairs for this period, you’ll need precise calculations to respond.
According to HMRC guidelines, there’s no time limit for submitting late tax returns, though penalties increase the later you file.
How accurate is this calculator compared to HMRC’s systems?
Our calculator is designed to match HMRC’s calculations precisely for standard employment scenarios. We use:
- The exact tax bands and rates published in HMRC’s official documentation for 2015-16
- Correct National Insurance contribution tables
- Accurate student loan repayment thresholds
- Proper handling of Scottish tax rates where applicable
However, there are some limitations to be aware of:
- Doesn’t account for complex situations like multiple jobs or irregular income patterns
- Assumes standard tax codes (may not reflect your actual coding notice)
- Doesn’t include benefits in kind or other complex income sources
- For complete accuracy with complex affairs, consult a qualified tax advisor
The calculator provides a good estimate for most employees, but for self-employed individuals or those with complex financial arrangements, professional advice is recommended.
What was the personal allowance for 2015-16 and how did it work?
The personal allowance for 2015-16 was £10,600. This was the amount of income you could earn before paying any income tax. Key points about the personal allowance:
- Income Limit: The allowance started to reduce by £1 for every £2 earned over £100,000, disappearing completely at £121,200
- Transferable: Introduced the Marriage Allowance this year, allowing transfer of £1,060 (10%) to a spouse
- Blind Person’s Allowance: Additional £2,290 available for registered blind individuals
- Age-Related Allowances: Being phased out – only available to those born before 6 April 1938
The personal allowance was significantly higher than in previous years (up from £10,000 in 2014-15), reflecting the government’s policy of increasing the tax-free amount year-on-year.
For Scottish taxpayers, while the personal allowance was the same, the way income above this threshold was taxed differed slightly due to the introduction of the Scottish Rate of Income Tax (SRIT) in 2016-17, though 2015-16 still used the UK-wide rates with minor variations.
How were National Insurance contributions calculated in 2015-16?
National Insurance contributions (NICs) in 2015-16 were calculated as follows for employees (Class 1 contributions):
| Earnings Range | Weekly | Annual | Rate |
|---|---|---|---|
| Below Primary Threshold | Up to £155 | Up to £8,060 | 0% |
| Between Thresholds | £155.01 to £815 | £8,060.01 to £42,385 | 12% |
| Above Upper Earnings Limit | Over £815 | Over £42,385 | 2% |
Key points about 2015-16 NICs:
- Primary Threshold: £155 per week (£8,060 per year) – no NICs below this
- Upper Earnings Limit: £815 per week (£42,385 per year) – rate drops after this
- Employer Contributions: 13.8% on earnings above £156 per week
- Self-Employed: Class 2 (£2.80/week) and Class 4 (9% on profits £8,060-£42,385, 2% above)
- Directors: Annual earnings period applies (different from weekly/monthly for employees)
NICs are calculated on a non-cumulative basis for employees (each pay period stands alone), which can sometimes lead to overpayments that can be claimed back.
Can I still claim tax relief for 2015-16?
The ability to claim tax relief for 2015-16 depends on the type of relief and your specific circumstances:
Still Possible to Claim:
- Pension Contributions: If you made personal pension contributions, you can still claim higher rate relief by submitting a self-assessment tax return
- Charitable Donations: Gift Aid claims can still be made if you have the proper documentation
- Work Expenses: If you have records of unclaimed work-related expenses (uniforms, tools, professional fees)
- Marriage Allowance: Can be backdated to 2015-16 if you were eligible but didn’t claim
No Longer Possible:
- ISA Contributions: The deadline for 2015-16 ISA contributions was 5 April 2016
- Capital Gains Tax: The annual exempt amount can’t be carried forward
- Most Tax Credits: Claims for this period are now closed
How to Claim:
- Gather all relevant documentation (P60s, receipts, bank statements)
- Complete a self-assessment tax return for 2015-16
- Include all claim details in the appropriate sections
- Submit to HMRC with any required evidence
- Be prepared for potential delays – HMRC prioritizes current year returns
For complex claims or large amounts, consider using a tax professional to ensure you maximize your entitlement while remaining compliant.
What were the key differences between English and Scottish tax in 2015-16?
While 2015-16 was the last year before the Scottish Rate of Income Tax (SRIT) was fully implemented, there were still some differences in how Scottish taxpayers were treated:
Income Tax Differences:
| Aspect | England/Wales/NI | Scotland |
|---|---|---|
| Personal Allowance | £10,600 | £10,600 |
| Basic Rate Band | £10,601-£42,385 | £10,001-£42,385 |
| Starter Rate (10%) | N/A | £10,001-£15,000 |
| Basic Rate (20%) | £10,601-£42,385 | £15,001-£42,385 |
| Higher Rate Threshold | £42,386 | £42,386 |
| Additional Rate Threshold | £150,000 | £150,000 |
Other Differences:
- Scottish Variable Rate: While not fully implemented in 2015-16, Scotland had the power to vary the basic rate by up to 10p (though didn’t exercise this power until 2016-17)
- Land and Buildings Transaction Tax: Replaced Stamp Duty Land Tax in Scotland from 1 April 2015
- Scottish Landfill Tax: Replaced UK Landfill Tax from 1 April 2015
- Council Tax: Different banding system and rates set by local Scottish authorities
The main practical difference for most taxpayers in 2015-16 was the 10% starter rate band for income between £10,000-£15,000, which didn’t exist in the rest of the UK. This provided a small tax saving for Scottish taxpayers earning in this range.
How does this calculator handle student loan repayments for 2015-16?
Our calculator accurately models the student loan repayment system as it operated in 2015-16:
Repayment Thresholds:
- Plan 1: £17,335 annual threshold (£1,444.58 monthly, £333.37 weekly)
- Plan 2: £21,000 annual threshold (£1,750 monthly, £403.85 weekly)
Repayment Rates:
- 9% of income above the threshold for both plans
- Calculated on gross income before tax and National Insurance
- Deducted automatically through PAYE for employees
How the Calculator Works:
- Determines which plan you selected (or none)
- Calculates annual income above the relevant threshold
- Applies 9% to this amount
- For monthly/weekly calculations, divides the annual figure by 12/52
- Displays the total annual repayment amount
Important Notes:
- Repayments only start in the April after you leave your course
- The calculator assumes you were making repayments during 2015-16
- For part-year repayments (e.g., graduated mid-year), the calculator may overestimate
- Interest rates varied: RPI + up to 3% for Plan 1, RPI + up to 3% for Plan 2
For precise student loan calculations, you might want to cross-reference with your official student loan statement from the Student Loans Company.
