As it's tax transparent (each shareholder are taxed based︃ on their home tax rate, in their home country), a Scottish LP is generally use︄ to split the revenue between official and taxed source in your country, and an offshore︅ and also to use a DTT to avoid 30% withholding as Google is based in︆ the USA for payments.
An example:
You sell a software via google, you can't use︇ an offshore or Google will apply a 30% withholding rate and you'll have a crapload︈ of money that you couldn't use to live.
You set up a Scottish LP with︉ two shareholders: 1 company in your own country and 1 offshore (with nominees). You split︊ the shares 30% home country 70% offshore.
If you earn 100k profits before tax and︋ your corporate tax in your home country is 20%:
Home country taxes: 100k x 0,30︌ x 0,20 = 6k | net profit = 100k x 0,30 - 6k = 24k.︍
Offshore taxes: 100k x 0,7 x 0 = 0 | net profit = 100k x︎ 0,70 = 70k
Total profit = 94k and you have an "official" revenue in your️ home country, you're not jobless without any known source of revenues...
But with this setup, I strongly advise to have an experienced CPA and tax lawyer, as sooner or later your own tax office will start to ask questions.
