Some of the specific assumptions for the UK include:
- Withdrawals from a pension program - In the lifegoals, at the point of retirement 25% of money in a pension program is removed tax free. The balance is fully taxable.
- There are deductions for taxable income for:
- Personal Allowance (automatically included)
- Personal Allowance (Standard) of £6,475
- Personal Allowance for people aged 65-74 of £9,490
- Personal Allowance for people aged 75 and over of £9,640
- Income limit for age related Allowances is £22,900 (The personal allowance is an amount that is deducted from the annual income of the resident and is considered tax free. The age allowances reduce where the income is above the income limit – by £1 for every £2 of income above the limit.)
- Self-employed expenses (tax deductible)
- Charitable contributions
- Interest income and net rental income is fully taxable
- Dividend income is subject to a 11.11% (1/0.9) gross-up. If you receive a dividend of £9,000 divide by 0.9 and the grossed up income is £10,000. The grossed up amount flows through as personal income and is taxed at the relevant income tax band. To offset the difference between personal income tax rates and dividend tax rates, 10% of the grossed-up amount is added back as a credit. The difference between the dividend tax rate and personal income tax rate is also added back as a tax deduction. In this example, the grossed-up dividend of £10,000 would be taxed at the personal income tax rate of 20%, resulting in £2,000 of tax. The effective tax rate for dividends in this band is 0%, so we add back 10% of the grossed-up £10,000 as well as the difference in tax rates, 10% here, multiplied by the grossed-up value, which sums to £2,000 and cancels out the net tax.
- As another example, we have £72,000 in dividends, bringing us to the next income tax band. The grossed-up amount is £80,000 which is taxed at 40%, for £32,000 of tax. Adding back the 10% credit and the difference in tax rates, 7.5% in this case, we end up with a tax credit + reduction of 17.5% x £80,000 = £14,000. Removing this from the taxes payable, we end up with £18,000 in taxes, for an average tax rate of £18,000/£72,000 = 25% on the dividends.
- Capital gains are not included in taxable income, but subject to a separate tax of 18% on any gains above £10,100 in a year.
- As of 2010, taxes are calculated at the following rates:
National Insurance Contribution
- In addition to normal income taxes, UK residents must pay contributions to the National Insurance program. To simplify the calculation, all clients are considered Class 4 contributors.
- £0 to £5,714 @ 0%
- £5,715 to £43,875 @ 8%
- £43,876 and above @ 1%
