Google translation from one Finnish thread:
"Trade Tracker such as affiliate networks have a tax ruling that the income is not required to provide withholding tax. Teadedoubler acquired that I remember in 2006 the tax authorities.
Affiliate revenue should begin to pay value added taxes when they should be a year about 10 k €. That's the kind of kinky feature of the VAT must be paid in respect of income which you have not charged VAT as a (a is odd, yeah). This strangeness due to the tax authorities give a bit of fishing line.
In practice, how things go:
You can take the profit but the bank account and deducted from your expenses and mark the difference between a tax return under Other income. You get to do that as long as VAT income limit is not exceeded during the tax year. Receipts for expenditure should be saved and statement made form, was there 15 or 16. That is, as long as the income is about € 5,000 a year, no problem.
If the income begins to rise over a year that has to be very careful that the VAT due perverssiyden. If you believe that your affiliate income exceeds 8500 euros per year, the sun must then take it to the y-ID and go to the VAT-register before the year when the revenue has been rising more than that limit. In practice, the bases of the business name in the previous year when revenues threatens to rise above the limit. At the time you register the networks and Google and they add VAT to the invoice of the statement (Google does not välttis because they work as I recall the reverse VAT obligation)."
