Or why it is sometimes difficult to understand a company's tax bill.....

Take a company which has made a £100k profit BUT £85k of this is from selling an asset, such as a specialist equipment.

The Chancellor chose this headline, but I think Investors also get a look in.

(SMALL) MAKERS

I take this to be businesses. In fact, it's largely small to medium companies that benefit from today's announcements being the changes to AIA, SEIS and R&D.

1. 4 Years - If you are in the first 4 years of your business and make a loss, you can use this loss to reduce your tax bill in the previous 3 years, such as from the job you had before you set up your business. You will receive a tax refund.

2. £5,725 - If your profits are lower than £5,725, you don't have to pay the annual £140 Class 2 NI, unless you need a credit towards your state pension. Ask for a repayment for earlier years.

3. £7,755 - If your profits are higher than £7,755, you will pay 9% Class 4 NI. This gets you no state benefits and effectively increases your tax rate from the 20% income tax rate to a total 29% tax rate.

Necessarily a muted Budget, as the Chancellor had little room for manoeuvre, but there were a couple of surprises to keep us interested!

Giving a £2,000 credit from April 2014 against employer's national insurance is a welcome initiative which may encourage small businesses to take on some staff.
