Frequently Asked Questions

How do I know if I have to file quarterly tax payments?
The IRS requires quarterly estimated tax payments to be filed by all the freelancers who have income that is not subject to automatic withholding (W-2 employees). Thus, if you are self-employed and turning a profit then you probably owe quarterly taxes. In simple words, if you have income that didn't have taxes withheld and you expect to owe $1,000 or more in taxes on all of that combined income in April, then you should consider paying quarterly taxes.
Why do I have to pay quarterly taxes?
Income received from just about any source is generally subject to income tax. That may include not just the federal income tax, but also the state income tax, and Social Security and Medicare tax.
Should self-employment taxes be paid quarterly or yearly?
Generally, as a self-employed individual, you are required to file an annual return and pay your estimated tax quarterly. You must pay self-employment tax (SE tax) as well as income tax. Estimated tax is necessary to pay Social Security and Medicare taxes and income tax because you do not have an employer withholding these taxes for you. Please refer to Form 1040-ES, Estimated Tax for Individuals to figure these taxes.

What if I overpay my estimated taxes?
If you overpay your estimated taxes, the IRS will send you a tax refund for the amount you overpaid. It has been observed that over 75% of freelancers overpay their taxes since they do not consider tax deductions while estimating quarterly taxes. This leads to either over payments or penalties. However, with FlyFin, there’s no such thing as an overpayment. The A.I. detects every possible deduction and helps you lower your tax amount.
What is the penalty for not paying quarterly taxes?

If you fail to pay your quarterly taxes, the IRS can charge you a penalty. Especially, if you owe more than $1,000 in taxes and do not pay these taxes quarterly, you’ll be charged with an underpayment penalty by the IRS.

However, you can avoid the penalty if you meet either of these conditions:

  • You had no tax liability for the previous year, and you were a U.S. citizen or resident alien for the whole year.
  • The total tax shown on your previous year’s tax return minus the amount of tax you paid through withholding is less than $1,000.
  • You’re a farmer or fisherman, and your withholding plus quarterly estimated tax payments are at least 66.67% of your previous year’s tax.
  • A casualty or disaster occurred.
  • You’re retired or disabled.
What percentage should I pay for estimated taxes?
It is generally advised that the taxpayers must pay at least 90% of their taxes throughout the year through withholding, estimated or additional tax payments, or a combination of the two.
How to request an abatement of the tax penalty?

You can file Form 843 if you wish to waive your penalty. However, to file for a waiver, you must meet any one of the following conditions:

  • Your estimated quarterly payments were accurate and timely.
  • You generated a large sum of your income later in the year.
  • A huge part of your tax payments occurred earlier in the year.
  • You changed your filing status to or from married filing jointly.
