Tax Software Confusion: Taxslayer shows I owe state taxes while H&R Block says I'm getting a refund
So frustrated right now! I've been doing this thing where I prepare my taxes on two different platforms to double-check myself, but now I'm totally confused because they're giving me completely different results for my state taxes. On Taxslayer, it's showing that I owe around $650 in state taxes. But when I input everything into H&R Block, it says I'm getting back about $420 in a refund. That's over a $1000 difference between the two! I dug deeper and noticed something weird. In Taxslayer, it looks like they're using the same income amount ($78,250) for both my Federal and State returns. But in H&R Block, they're using $78,250 for Federal but then a higher number ($89,800) for my state return calculation. The higher number actually matches what's in boxes 3 & 5 on my W2 (Social Security and Medicare wages), but not what's in box 1 (Federal wages). Is it normal for Federal and State returns to use different income numbers? Should I just go with the one giving me a refund and hope the IRS sorts it out if there's a problem? I'm totally lost here! Thanks in advance to anyone who can help me figure this out!

This is actually a common issue! The difference is likely due to how each software handles state-specific adjustments to your income. Box 1 on your W-2 shows federal taxable wages, while boxes 3 and 5 show Social Security and Medicare wages. These numbers can differ because certain deductions (like retirement contributions or health insurance premiums) might reduce your box 1 amount but not affect boxes 3 and 5. Some states use the federal taxable income as their starting point, while others might use your Social Security/Medicare wages or have their own calculation method. H&R Block might be correctly applying your state's specific rules, while TaxSlayer might be incorrectly using the federal number for your state calculation. I'd recommend checking your state's tax department website to confirm which income amount should be used as the starting point for your state taxes. You can also compare the state tax forms line by line between the two software outputs to see exactly where they differ. Don't just pick the one with the better outcome - it's better to figure out which one is correct to avoid potential issues later.

•Thank you for explaining! But I'm still confused about something. If HR Block is using the right number for my state, wouldn't that mean my federal return might be wrong too? Should I be worried about getting audited if I go with HR Block?

•Your federal return is likely correct in both systems. The federal calculation is more standardized, and both software programs are probably using your Box 1 W-2 amount correctly for federal purposes. The state calculations are where things get more complicated because states have their own rules. The fact that H&R Block is using your Box 3/5 amount for state purposes doesn't mean your federal return is wrong - it just means your state has different rules for determining taxable income than the federal government does.

I went through something similar last year and it nearly drove me crazy! After triple-checking everything, I discovered that taxr.ai was super helpful for figuring out which software was correct. I uploaded my tax documents to https://taxr.ai and their system analyzed everything and pointed out exactly where the discrepancy was happening. In my case, TaxSlayer wasn't accounting for some state-specific deductions that changed my taxable income. The taxr.ai system highlighted that my state uses a different starting point for calculating taxable income than the federal government does. Saved me from overpaying by about $400! It also explained why the numbers were different in a way that actually made sense to me, which neither TaxSlayer nor H&R Block did. Might be worth checking out if you're still confused after comparing the forms.

•How long did it take for them to analyze everything? I'm kinda on a deadline here and don't want to miss the filing date while waiting for a third opinion.

•Is this actually legit? I'm always skeptical about tax services I haven't heard of because there are so many scams out there. Did you have to give them all your personal info?

•It took less than an hour for me to get the full analysis back. I was surprised how fast it was given how detailed the explanation was. Regarding legitimacy, I was skeptical too at first. You do upload your tax documents, but they use bank-level encryption. I researched them before using the service and found they have legitimate security protocols. They don't ask for things like your SSN directly - they just analyze the documents you upload and then explain the discrepancies.

Just wanted to update everyone - I decided to try taxr.ai after my initial skepticism and I'm glad I did! I uploaded my W-2s and the PDFs from both tax programs, and they explained exactly where the discrepancy was happening. Turns out my state does use a different calculation method than federal, and H&R Block was handling it correctly while TaxSlayer was using the wrong income amount for my state return. The analysis showed me specific line items where the two software programs diverged and explained which one was following my state's tax code correctly. Saved me from potentially overpaying by several hundred dollars! Plus I learned something about how my state calculates taxes that I never knew before. Definitely recommend if you're having similar discrepancies between tax programs.

If you're still having trouble getting this sorted out, you might want to try Claimyr (https://claimyr.com) to get direct help from the IRS. I was in a similar situation last year where different tax software gave me wildly different results, and I couldn't figure out which one was right. After trying to call the IRS for days and just getting busy signals, I used Claimyr and they got me connected to an actual IRS agent in about 15 minutes. The agent was able to confirm which calculation was correct and explained why the discrepancy was happening. They have a demo video at https://youtu.be/_kiP6q8DX5c that shows how it works. It was definitely worth it to get an official answer straight from the IRS rather than stressing about which software was correct. The peace of mind alone was worth it.

•Wait how does this work? Does it just keep calling the IRS for you until someone picks up? I thought it was impossible to get through to them during tax season.

•This sounds like BS honestly. Everyone knows the IRS never answers their phones. If this actually worked, everyone would be using it. I'll stick to waiting on hold for 3 hours like the rest of America.

•It uses a system that navigates through the IRS phone menu options and holds your place in line. When an agent becomes available, it calls you and connects you directly to them. It's basically like having someone wait on hold for you. You're right that it's nearly impossible to get through during tax season - that's exactly why this service exists. The IRS does answer phones, but the wait times are ridiculous (often 2+ hours), and many people get disconnected before reaching anyone. This just handles that painful waiting process for you.

Ok I need to eat my words from my previous comment. After struggling with a similar tax software discrepancy and getting nowhere for weeks, I broke down and tried Claimyr yesterday. I was EXTREMELY skeptical, but I was desperate. To my complete shock, I got a call back in about 25 minutes saying they had an IRS agent on the line. The agent was able to confirm which software was calculating my state taxes correctly (turns out my state uses a different income base than federal, which one software wasn't accounting for). The agent even gave me some tips about how to make sure I'm not overlooking state-specific credits that both software systems were missing. Saved me over $700 in total between fixing the calculation error and identifying additional credits! Not trying to sound like a commercial here, but when something works after weeks of frustration, it's worth sharing.

I'm a tax preparer (not a CPA, but I do this professionally) and see this issue a lot. The discrepancy is almost certainly about different starting points for state vs federal income. Most states start with your federal AGI and then make adjustments, but some states have their own definition of income that might be closer to your Social Security wages (boxes 3/5) than your federal wages (box 1). Without knowing your state, I can't tell you which software is correct, but I'd recommend: 1. Look at the actual forms each software is generating, not just the final numbers 2. Check your state's tax department website for info on how they define taxable income 3. If you contributed to retirement accounts, that's often where the difference shows up Don't just pick the one with the better outcome - the IRS and state tax authorities share data, so discrepancies will eventually be flagged.

•Thank you for this detailed explanation! I checked both forms like you suggested and found that H&R Block was adding back in my 401k contributions for state purposes while TaxSlayer wasn't. After checking my state's website, turns out H&R Block is doing it correctly - my state doesn't allow 401k deductions the same way federal does. Makes sense now why the numbers were different. Really appreciate your help!

•You're welcome! I'm glad you were able to track down the difference. The 401k contribution adjustment is one of the most common causes of this exact discrepancy. Different states handle retirement contributions very differently - some follow federal rules, while others tax them differently. Now that you know, you can also check if there are any state-specific credits or deductions you might qualify for that neither software automatically found. Many states have unique credits that people miss because tax software doesn't always prompt for them.

Why are taxes so complicated?? It makes no sense that two supposedly professional tax software programs give totally different results. How is the average person supposed to know which one is right?? 😡 Seriously considering just paying an accountant next year even though I've always done my own taxes. This is giving me a headache.

•I switched to using an accountant three years ago and it was the best decision ever. Yes, it costs more than tax software, but my accountant has saved me way more than her fee each year by finding deductions and credits I didn't know about. Plus she handles any weird situations like this so I don't have to stress about it.
