Hi @Ewaters17  here is a more detailed explanation to help determine if you should or should not pay quarterly.

Do I have to make estimated tax payments?

It depends. The general rule is that you must pay as you go. Meaning that when you file your tax return, if you haven't paid enough taxes through withholdings or estimated tax payments then you might owe an underpayment penalty. 

 

To determine whether you need to make quarterly estimates, answer these questions:

 

1. Do you expect to owe less than $1,000 in taxes for the tax year after subtracting your federal income tax withholding from the total amount of tax you expect to owe this year? If so, you're safe—you don't need to make estimated tax payments.
2. Do you expect your federal income tax withholding (plus any estimated taxes paid on time) to amount to at least 90 percent of the total tax that you will owe for this tax year? If so, then you're in the clear, and you don't need to make estimated tax payments.
3. Do you expect that your income tax withholding will be at least 100 percent of the total tax on your previous year's return? Or, if your adjusted gross income (Form 1040, line 8b) on your tax return was over $150,000 ($75,000 if you're married and file separately), do you expect that your income tax withholding will be at least 110 percent of the total tax you owed for the previous year? If so, then you're not required to make estimated tax payments.

 

If you answered "no" to all of these questions, you must make estimated tax payments using Form 1040-ES. To avoid a penalty, your total tax payments (estimated taxes plus withholding) during the year must satisfy one of the requirements above.

If you only pay at the end of the year on your tax return you may owe a penalty for not paying in during the year.   You should still send in some quarterly.  You will get a refund if you over estimate the amount.

 

You must make quarterly estimated tax payments for the current tax year if both of the following apply:

- 1. You expect to owe at least $1,000 in tax for the current tax year, after subtracting your withholding and credits.

 

- 2. You expect your withholding and credits to be less than the smaller of:

    90% of the tax to be shown on your current year’s tax return, or

  100% of the tax shown on your prior year’s tax return. (Your prior year tax return must cover all 12 months).

Thank you!  How would one go about sending in these quarterly payments.  Do you do it through a software like turbotax or quickbooks? or you have to send it in directly?
