Hi Invincible,
In the UK, in general you are required to register for VAT when your annual sales exceed £67,000.
HMRC (Her Majesty's Revenue and Customs) are responsible for all tax affairs, including VAT.
The webpage which explains when you must register for VAT can be found here:
http://www.hmrc.gov.uk/vat/reg-how-to.htmIf you registered for VAT in the UK, you would invoice your customer net of VAT (i.e. 0%), as long as he gives you his German VAT number.
If your annual sales are not going to exceed £67,000 (around 85,000 EUR using HMRC's exchange rate) then I would advise that you do not register for VAT.
Why not? Well, you would still end up charging your German customer the same amount. Being VAT registered means that you have to fill out monthly (or quarterly, if you request this from HMRC) VAT returns. These are quite simple, much easier than the German equivalent. However, it is an 'extra' responsibility, it will take up your time and means you have to keep excellent records. The VAT people have more powers than the police, so you must make sure you do everything right.
HOWEVER, registering for VAT does have some good points. Basically, if you pay VAT on your business purchases, then if you have a VAT number then you can claim this VAT back. For example, you might pay UK VAT on stationary, computers, petrol (for business use) etc.
So, you need to weigh up the advantages and disadvantages of registering for VAT. If you don't expect to have many business expenses, then I would advise against registering.
One thing to note - it sometimes takes several months to receive a UK VAT number because HMRC like to carry out various checks to make sure your application is legitimate. This is because over the past years criminals have been exploiting the VAT system in the UK.
Setting up a limited company in the UK is cheap and easy. On
www.ukplc.net you can set one up over the internet.
With a limited company, you can keep your personal and business life separate. There are also tax advantages. By owning a limited company (i.e. owning the shares), you can pay yourself a small salary, and then the rest in dividends.
Basically in the UK we have two taxes on income. Income tax, and National Insurance (NI).
Information about income tax:
http://www.hmrc.gov.uk/rates/it.htmInformation about national insurance:
http://www.hmrc.gov.uk/rates/nic.htmIf you set up a limited company you will pay Class 1 and Class 1b National Insurance contributions.
National Insurance is only applied to your SALARY. However, DIVIDENDS are not subject to National Insurance.
Consequently, you can pay yourself a small salary and large dividends, and then you do not pay much National Insurance.
Company profits are taxed at 20%. [edit - for tax year 2008/2009 this will increase to 21%]
If you have any questions, just ask.

Nicholas
