Hi. I hope I wrote this post in the correct section. I have a question about tax from the developers side. If I write a script (lets say CMS or whatever) and start selling it. Lets say the copy of it costs about $10/month or whatever. Do I have to pay some kind of tax? Do I have to reach a particular amount of sales? What tax would be for 100 copies and 10000 copies? Each of them would need to pay $10 so it would be $1000 - $10000 in total. Thanks in advance.
Looks like you are in UK so my answer may not be correct for you. In the US you would be selling a product and all sales would need to be reported as gross income then subtract any R&D cost (amortiized) and ongoing expenses. The remaining balance is profit and on that you pay taxes. From other discussions the UK is pretty much the same but the % are different and I don't think you guys have a social security type tax which is a flat 15.3% of net in the states.
Of course you'd have to pay taxes! You'd be better off asking this to more local folks unless there's some around
You have to declare the income after you make so much with it. I'm not sure what it is in the UK but probably only a few hundred pounds. You'll have to add it to your total income and pay whatever taxes you owe.
You have to make sure you keep note of everything that you earn and then you report it when doing the income tax.
