Let me try to simplify this with an example: Let's say: - Your 2024 tax was $8,000 - Your 2025 tax turns out to be $12,000 To avoid penalties for 2025, you need to have paid the SMALLER of: - 90% of $12,000 = $10,800 - 100% of $8,000 = $8,000 Since $8,000 is smaller, that's your target. If you paid at least $8,000 during the year through withholding or estimated payments, no penalty! The rule is designed to protect you when your income increases unexpectedly.
What about if you're a high-income earner? I heard there's a different percentage for people making over a certain amount. Is it still "whichever is smaller" in that case?
You're right to ask about high-income situations! If your AGI was over $150,000 (or $75,000 if married filing separately) in the prior year, the rule changes slightly. Instead of 100% of your prior year tax, you need to pay 110% of your prior year tax. So using the same example but assuming you're a high earner: - 90% of $12,000 = $10,800 - 110% of $8,000 = $8,800 In this case, $8,800 would be smaller, so that's your target to avoid penalties. And yes, it's still "whichever is smaller" - the IRS just adjusts the prior year percentage for high-income taxpayers.
Kinda related, but does anyone know if this rule applies the same way for self-employment taxes? Like if most of my income is from 1099 work? I'm trying to figure out how much to set aside each quarter.
Yep, the same rules apply for self-employment income. Your required estimated tax payments (to avoid penalties) still need to cover the SMALLER of 90% current year or 100% prior year (110% if high income). The difference is you need to include both income tax AND self-employment tax in your calculations. A good practice for self-employed folks is to set aside 25-30% of your income for taxes (including SE tax), but using last year's total tax as your safe harbor amount is usually the easiest way to avoid penalties if your income is growing.
You should check if both programs are including the same business income in the QBID calculation. I had a similar issue and discovered TurboTax was missing some 1099-NEC income in the QBID calculation but including it in my total income. Make sure all your Schedule C businesses are being included properly in both software. Also, did you indicate different business types between the two software? That can affect the QBID calculation too.
Thanks for the suggestion! I double-checked and both programs have the same 1099-NEC income included, but I noticed TurboTax has my photography business categorized as "Arts & Entertainment" while TaxAct has it as "Professional Services." Could that make such a big difference?
Yep, that could absolutely cause the difference! The business classification can significantly impact how the software calculates your QBID. "Professional Services" might be triggering TaxAct to apply different limitations or calculations than the "Arts & Entertainment" category in TurboTax. Try changing the classification to match in both software and see if that resolves the discrepancy. Based on IRS guidelines, photography would typically fall under "Arts & Entertainment" rather than "Professional Services" unless you're doing commercial/corporate work specifically.
Has anyone done a side-by-side accuracy comparison between TurboTax and TaxAct? I've been using TurboTax for years but the price keeps going up and I'm thinking of switching.
I've used both for the last three years. TaxAct is significantly cheaper but I've found TurboTax catches more deductions, especially for business owners. That said, TaxAct has gotten much better with their interface recently. If your taxes are relatively straightforward, TaxAct is probably fine and will save you money.
15 Just sharing my timeline for comparison - filed on 2/3/25, acceptance same day, received verification letter automatically on 2/24/25 without requesting it, then refund deposited on 3/6/25. It seems really random who gets automatic verification letters and who doesn't. I didn't have anything unusual on my return though - just standard W-2 income and standard deduction.
4 Did you claim any tax credits like the Earned Income Credit or Additional Child Tax Credit? Those usually trigger automatic verification letters because they have special processing requirements.
15 No special credits at all, which is why I was surprised to get the verification letter automatically. Just basic W-2 income, standard deduction, and a small amount of bank interest. Nothing that would typically flag for additional verification. I've heard some people say the automatic letters sometimes happen if it's your first time filing with a particular software or if you've moved since your last filing, but neither applied to me. It really does seem pretty random!
11 Anyone know exactly HOW to request the verification letter? Do you call the IRS or is there a way to do it online? I'm in the same boat - filed 2/5/25 and still nothing.
I've been a part-time preparer for 5 years and have never received a penalty. The key is documentation, documentation, documentation! For every return, I keep: - Notes from client interviews - Copies of all supporting documents - A checklist of due diligence steps for credits - Documentation of any unusual situations or positions taken Most penalties I've heard about among colleagues were for repeatedly failing to verify eligibility for refundable credits like EITC. If you create a systematic approach to verification and stick to it, you'll be fine.
That's super helpful! Do you use any particular software or system to manage all this documentation? I'm trying to figure out the best way to stay organized from the beginning.
I use a combination of tools. The tax software I use (Drake) has built-in due diligence worksheets that help tremendously. For document management, I started with a simple folder system but upgraded to SmartVault after my client load increased. I also created my own checklists in Excel for different types of returns (W-2 only, self-employed, rental property, etc.) that I complete for each client. The most important thing is consistency - whatever system you choose, use it for every single client, no exceptions. It becomes second nature after a while, and that's when you can feel confident you're protected against penalties.
One thing to consider is that a significant percentage of penalties comes from just a few specific areas: 1. EITC due diligence failures 2. Failing to verify child-related credits eligibility 3. Not properly confirming self-employment income/expenses 4. Knowingly preparing returns with suspicious refundable credits The IRS has limited enforcement resources, so they focus where the biggest tax gaps exist. If you're careful in these high-risk areas and maintain proper documentation, your risk is minimal.
That makes sense, but I've heard horror stories about preparer penalties being applied even when the preparer thought they were following the rules. Is there any protection or insurance available specifically for preparers?

Another option worth mentioning is that you can still mail a check with Form 1040-ES. Even though the form is meant for the estimated payment that was due in January, you can still use it to make a payment now. Just mail the check with the 2021 Form 1040-ES voucher for the 4th quarter, and make sure to clearly write "2021 Form 1040-ES" and your SSN on the check. The main downside compared to electronic payment is it will take longer to process, and you won't get immediate confirmation. But it's an alternative if you're having issues with the online system. Just keep in mind you'll still have the same potential penalty for the late payment regardless of which method you use.

ā¢Wouldn't the paper option take way longer to process though? I'm worried about making things worse by having the payment not get credited before I file my return in April. Is there a way to track when they receive and process a paper payment?

ā¢Yes, paper payments do take longer to process - typically 2-3 weeks, sometimes more during busy periods. If you're planning to file your return soon, the electronic payment through Direct Pay (using "Balance Due" option) would be much faster. For tracking a paper payment, the IRS doesn't provide direct tracking like a package. The best way to confirm they received it is by setting up an online account at IRS.gov and checking your tax account transcript, which will show when payments post to your account. You can also call the IRS, but as others have mentioned, the wait times can be very long. If you do mail a payment, I'd strongly recommend using certified mail with a return receipt so you at least have proof of when you sent it.

PSA for next year: If you have the IRS2Go app on your phone, it lets you make estimated tax payments through Direct Pay or a credit/debit card right from the app, and it sends you reminders before each quarterly due date. I used to forget my January payment every single year until I started using this.

ā¢Does the app charge extra fees like when you pay taxes with a credit card on those third-party processors? Or is it actually free like regular Direct Pay on the website?
