What is your monthly tax expense?

[thiccboygamerTTV]

For those generating income from YouTube or a website and are tax liable, how much is your monthly expense? For example, for someone earning 1500 TL, what is the amount left after deducting expenses? Let's say your income is 1500 TL, if 1000 TL goes to tax, 200 TL to insurance, and accountant fees, are these expenses deductible from taxes? Another question I have is this: I had a blog 2 years ago from which I received payments every 2-3 months. I decided to close the blog and AdSense account to work on YouTube, where I opened a new AdSense account. I recently learned about taxes and am considering requesting a ruling. Will I be penalized for this, and can I benefit from tax reductions for those under 29 years old?
