Is it to late to figure out my income and deductions for the last 3 quarters and see what I owe in taxes or should I just wait till the end of the year to put everything in?

Hi there, rbfr68805.

Thank you for visiting the QuickBooks Community. I'll ensure to share details on how QuickBooks Self Employed calculates your taxes and when to file and pay this one.

As a self-employed individual, generally you are required to file an annual return and pay estimated tax quarterly. These payments cover your income, Social Security, and Medicare taxes for your self-employed work.

Since QuickBooks Self-Employed tracks your self-employed income and expenses, it calculates what you need to pay each quarter. However, there are times that self-employed individuals are unable to make a profit for a specific quarter and the estimated tax payment is $0. It means you didn't make a profit for that quarter and if you know you made money, you'll have to make sure you entered and categorized all of your business transactions. When you file your taxes, you still need to report quarters when you didn't make a profit.

For more details about how taxes work, I recommend reaching out to the IRS or the Self-Employed Individuals Tax Center section of their website. Here's the link: Self-Employed Individuals Tax Center.
