2~4주째 단타 투자 중인 초보, 세금 걱정이네요💸

You buy 1 stock at $10. You then sell that stock at $20. You have a $10 gain.

You now owe taxes on that $10 you gained.

Edit: It gets more complicated than this for example a short-term hold of a stock less than 1 year has a higher tax rate than a long-term hold for more than one year. Depending on your income bracket you can write off certain amount of losses to help counter your taxes but that's based on your income.

The issue is less with what you’ll owe and how much of a pita it is to do your taxes.

If you’re with a broker that can tie directly into trubotax it’s nbd. Just watch out for wash sales in December.

If you’re with a broker that doesn’t import into TurboTax directly…. Well get ready to manually enter a crap ton of data

Don't worry, you only have to worry about taxes if you make money 

If you're just using the opportunity for learning and sticking with small amounts of capital the taxes will not functionally matter come tax season nor materially affect your operations if you're not using profitability as a constraint for selecting your trading strategy.

If you end up trading larger amounts of capital with a high income, the tax implications will be much more important as the risk reward profile changes since you earn less of your gains than you otherwise would due to your overall income.

don't worry about taxes, turbo tax will figure it out for you... it takes about 3 minutes per brokerage. guessing you aren't going to owe much, friend. good to think ahead.

This is actually a bit complicated, look it up. But one of the downfalls to day trading unless you're actually get a PDT designation by the IRS (which can be very hard to do) is you can take a loss and still pay taxes. How? Keeping it simple, you made $1,000 on your winning trades but lost $2,000 on your losing trades, so you're down $1,000. Guess what, you're still taxes on your $1,000 winning trades. But again, it's a bit more complicated than that but you cannot write off all of your losses.
