I declare them but i declare everything now as got audited last year and they hit me hard hence building another round up asap to find the money for the extra tax i owed.
Why did they audit you?
I used to do my returns myself and for the last 5 years i claimed my milage wrong. I thought it was 40p for every mile done but it turns out its 40p for any milage under 10000 and goes down to 25p anything above.
I had 20-40000 a year all at 40 since being self employed from running canvassing teams round the country and windows. Also i claimed £100 a month using my house as an office which they didnt accept so had to show everything for the past 6 years done. Luckily all my work done was fine, just the expensies didnt add up. I now use an accountant, not going through that again.
