Thanks everyone, really appreciate the replies (keep 'em coming if there are any more)!
I am in a very similar situation. Currently in the UK and earning some money online (hopefully enough to live on by June) and intend to move to NL later this year.
Currently I declare my tax as self-employment income. This is just another section on my personal tax return. But instead of declaring my income to the Dutch tax authorities with the added complication of possible employment in The Netherlands, I'm probably going to incorporate as a UK Ltd company.
Then when I am in NL I can hopefully just declare any income paid out as receiving a foreign (UK) dividend. It seems to be that this would simplify matters. Of course the tax on a UK company would be UK corporation tax.
But there could be further complications. My income from my website comes via direct payments to my UK bank account, some from Google UK but most paid from the US. Optionally I can change the US sourced income into cheque form or divert it into a bank account anywhere else in the world.
I am therefore looking into the possibility of an offshore or non-UK/NL company as this may be more tax efficient (note: I am NOT planning tax evasion) - although I freely admit I have no clue and need to find out more.
As you can see, online businesses are unique in that the income is frequently coming from overseas. Add to this another layer of complexity - when I work on my websites I am merely sending instructions from the UK. The websites themselves actually exist in the US at the moment. I can switch them to anywhere else in the world if I wish. I believe this is one reason why Panama has invested heavily in data centres and is encouraging websites to be hosted there - I am guessing that the key factor is where your site is located and not where you "work". Treatment of this may differ from country to country, I have no idea what it is in NL.
Probably the best and least complex way is for me to have a UK Ltd company and draw foreign dividends in NL for at least the first year or so, I can't see any problems with that. Then later look at tax efficiency.
As you can see, I've looked into this and am still none the wiser! Even an ordinary tax lawyer would probably be clueless about online business!
