Q1: 20% QBI Deduction

I left my full-time job early last year and now work as an independent freelance consultant. I will report my business income and expenses on Schedule C. I heard about a 20% deduction. Can you explain what this is and whether I can claim it on my 2024 Form 1040 for my self-employment earnings?

Owners of LLCs, S corporations and other pass-through entities, as well as self-employed individuals, can deduct 20% of their qualified business income (QBI). QBI is income less deductions from your business. An important limitation applies to high earners in certain service fields. They include health, law, accounting, consulting, financial and brokerage services, performing arts, athletics, actuarial science, investing or trading in securities, or any business where the principal asset is the reputation or skill of its employees. If you’re in one of the affected fields and your total taxable income on your 2024 Form 1040 (before the QBI deduction) exceeds $383,900 for joint filers or $191,950 for single filers and head-of-household filers, the 20% deduction begins to phase out (the 2025 amounts are $394,600 and $197,300).

When filling out your 2024 Form 1040, you would complete either Form 8995 or 8995-A and attach it to your return. Most people use the simpler, one-page Form 8995. The 8995-A is for taxpayers with incomes over the thresholds set forth above. You then claim the 20% QBI deduction on line 13 of your Form 1040.

Note that this deduction ends after 2025, unless Congress acts before then. It was first enacted in the 2017 Tax Cuts and Jobs Act (TCJA) to provide some federal income tax parity between C corporations, which are taxed at a 21% federal income tax rate, and pass-through businesses, in which the individual owners pay federal income tax on their earnings up to a 37% tax rate.

Q2: Estimated Tax Payments

I filed the 2024 federal tax return for my wife and me using TurboTax. TurboTax printed out the quarterly estimated tax payments to make for 2025. If we make these estimated tax payments on time, will that protect us from being penalized for underpayment of taxes?

You won't have to pay the underpayment penalty for 2025 if you prepay, through estimated tax payments or withholding, at least 90% of your 2025 total tax bill or 100% of your 2024 total tax bill (110% if your adjusted gross income for 2024 exceeded $150,000). My thought is that the TurboTax quarterly estimated tax payment schedule is based on 100% (or 110%) of your 2024 tax liability. If that's the case, then you should be fine. Note that if, closer to year-end, you believe that you did not make enough estimated tax payments, you can always request more income tax withholding from your employer (if you're working) or from your Social Security benefits or IRA distribution (if you are retired). Tax withheld at any point in the year is treated as if evenly paid throughout the year.

Q3: Tax Return Filing Due Date

I live in Florida and I heard that I can file my 2024 Form 1040 later than April 15. Is that correct, and if so, when do I have to pay my taxes?
The normal deadline date for filing the 2024 Form 1040 is April 15. But the IRS has given taxpayers in federally declared disaster areas more time to file and pay their federal taxes. Taxpayers in all of Alabama, Florida, Georgia, North Carolina and South Carolina, and parts of Alaska, New Mexico, Tennessee, Virginia and West Virginia, have until May 1 to file their Forms 1040 and pay taxes because of hurricanes and other disasters that occurred in those states in 2024. Victims of the early January Southern California wildfires have until October 15. And victims of the 2025 flooding and storms in Kentucky and West Virginia have until November 3. As a Florida resident, you have until May 1 to file your 2024 Form 1040 and pay any taxes that are due.

Q4: Return Filing Extension

I live in Florida, and I won’t be ready to file my 2024 Form 1040 by May 1. What is the due date for getting a filing extension?
Since the IRS has extended the deadline for Florida residents, for filing 2024 federal returns and paying federal taxes, to May 1, 2025, then you would have until May 1 to file Form 4868 to extend the May 1 due date for filing your 2024 Form 1040 to Oct. 15. To get the extension, a taxpayer must file Form 4868 by the original due date for the return, whether that is April 15 or another extended deadline date. So, in your case, May 1 is the deadline to file Form 4868.

However, if you want to file the Form 4868 electronically, you must do so by April 15. After that, you can only file the 4868 on paper. According to IRS, "though disaster-area taxpayers also qualify to request a tax filing extension between April 15 and May 1, 2025, these requests cannot be filed electronically. They can be filed only on paper."

It’s important to note that the Form 4868 extension applies only to extend the due date for filing your federal return, not to paying any taxes that you might owe. So, make sure that if you think you will owe taxes for 2024, you estimate the amount and pay the taxes with your extension by May 1.

In general, there are several ways to get an extension. You can use the IRS’s Free File to e-file Form 4868 and pay if you expect to owe tax. You can pay electronically through the IRS’s Direct Pay service or the Electronic Federal Tax Payment System (EFTPS). You can pay by credit card. You can use tax preparation software. Or you can mail a paper Form 4868 to the IRS with your payment.
