Well congratulations on going from student to tycoon in just one year. That's quite an accomplishment!
The answer to your question is yes, the IRS can summons your bank transactions if they feel it is necessary to do so. They would normally only do this in a case where they suspected that your income was under-reported. They would be looking more for deposits that you made, rather than the payouts from your account.
But as long as you have receipts for all of your expenses, then it would not necessarily mean they would need to see your bank records. There is no way to offer any real assurance this would not happen, because if you were to be audited, each examiner assigned to an audit
makes his own decisions on what they feel is required as far as records and documentation.
But requiring your actual bank records normally would occur more in a case where someone reported say $100,000 in income and $90,000 in expenses. The IRS would be a little suspicious that you could have lived on the remaining $10,000 profit which is all you claimed you had. As long as your expenses are not an outrageous percentage of your income, this would not normally be an issue.
Thank you againCustomer and let me know if you have more questions.
