Julie, thank you for your reply. Please accept my apologies for the delay in writing to you.
You have stated your maximum annual earnings have been £7,800 and minimum annual earnings were £3,600 over the last 7 years.
Personal allowances and Class 2 NIC small earnings exemption for the past years were
Tax year PA Class 2 NI Class 2 weekly rate
2007-08 £5,225 £4,635 £2.20
2008-09 £6,035 £4,825 £2.30
2009-10 £6,475 £5,075 £2.40
2010-11 £6,475 £5,075 £2.40
2011-12 £7,475 £5,315 £2.50
2012-13 £8,105 £5,595 £2.65
2013-14 £9,440 £5,725 £2.70
Depending on income per tax year...your maximum exposure to income tax is on taxable income of (7,800-5,225) = 2,575 in tax year 2007-08 and the tax on it is (2,230 x 10%)+(345 x 22%) = £298.90 say £300.
If you have earnings over the small earnings exemption limit for Class 2 NIC then you should have paid a weelky contribution as shown above for the year your earnings exceeded the exemption limit.
How to correct the situation ... a practical advice
You should preparea statement of income and expenses for each year you had earnings . I presume you were self employed. If you were not self employed then these would be regarded as casual income not taxed at source.
Ascertain whether your income exceeded the personal allowance or not ...
Example -Tax year 2009-10
Casual earnings = 5,050
Allowable expenses = 450
Casual earnings after expenses = 4,600
Personal allowance = 6,475
Taxable income = £nil
Class 2 NIC
Income = 5,050
(small earnings exemption) = 5,075
Class 2 NIC payable = £nil
Write to HMRC advising you had casual income in the tax years (state what they are) as shown in the schedule and ask if you need to complete a tax return. If HMRC decide you should have completed a tax return then they would issue you with a Unique Tax reference number (UTR) ..it is ten digit reference number (if you don't already have one) and also advise for which years you should complete a tax return.
You may find HMRC decide there is no need for you to register for self assessment and to file a tax return as your income is
Casual income and that they don’t see you as self employed in the true sense
The earnings are below personal allowance and within the small earnings exemption limit for Class 2 NIC
More information on who needs to complete a tax return and registration for self assessment can be found here
If HMRC decide you should have registered for self assessment then you may have to pay a penalty for late registration etc. More information on late registration etc can be found here
