Marc Hogan, writing on Wondering Sound:
For musicians affected, the problems are real, too. British businesses that sell e-books, apps or, yes, music downloads would be required to pay VAT on sales to customers in all the different countries of the EU, with some 30 different tax rates. Though Bandcamp will handle the details, EU-based indie labels and artists would still be required to file quarterly VAT reports and keep their records for 10 years—not exactly what they were expecting when they got into this business, one can safely assume.
Bad news—and lots of extra complications—for independent musicians as well as small businesses.
