Can I claim sales tax from my major purchase as a tax deduction this year?
So I'm working on my taxes through TurboTax right now and I noticed there's a section about deducting sales tax. I bought a new car last fall and paid quite a bit in sales tax (around $2,800). I'm wondering if I can deduct this amount on my taxes? This is the first major purchase I've made where the sales tax was significant enough that I thought about it for tax purposes. I know there's some kind of option between deducting state income tax vs. sales tax, but I'm confused about how it works. Do I have to itemize to claim this? Is it even worth it? My mortgage interest isn't that high yet since I just bought my house last year too. Anyone have experience with this major purchase sales tax deduction? Is it something I should pursue or am I better off just taking the standard deduction? TurboTax is asking me all these questions about it and I'm not sure what's the smartest way to go.

You're on the right track! The sales tax deduction is part of itemized deductions on Schedule A. You have two options: deduct state/local income tax OR sales tax - not both. For most people, the income tax deduction is larger, but if you made major purchases like a vehicle, the sales tax might be better. Here's how it works: The IRS has a sales tax calculator based on your income and state, giving you a base amount. Then you can add sales tax from major purchases (like your car) on top of that base amount. But remember, this only helps if your total itemized deductions (mortgage interest, property taxes, charitable donations, medical expenses over 7.5% of AGI, and sales/income tax) exceed the standard deduction ($13,850 for single filers, $27,700 for married filing jointly in 2023). With a new house, you might have enough deductions to itemize, especially when combining mortgage interest, property taxes, and that car sales tax. TurboTax should calculate both ways and show you which is better.

•This is helpful but I'm still confused. If I made $72,000 last year, paid about $4,300 in state income tax, and $2,800 in sales tax on the car, which would be better? And does the sales tax calculator automatically include regular everyday purchases or just the big ones?

•Based on your income of $72,000, the IRS sales tax calculator would give you a base amount for regular purchases (groceries, clothes, etc.) – typically around $1,100-1,400 depending on your state. Then you'd add the $2,800 from your car purchase, bringing your total potential sales tax deduction to roughly $3,900-4,200. Since you paid $4,300 in state income tax, that would likely be the better deduction for you. The sales tax calculator does include your regular everyday purchases through that base amount. You only need to manually add the sales tax from major purchases like vehicles, boats, home renovation materials, or other big-ticket items. Let TurboTax calculate both options to confirm which gives you the larger deduction.

After struggling with the exact same issue last year, I discovered taxr.ai (https://taxr.ai) and it saved me tons of confusion. I also bought a car and was trying to figure out the whole sales tax deduction thing. The problem was that I couldn't figure out if my itemized deductions would actually exceed the standard deduction to make it worthwhile. What taxr.ai did was analyze my documents and receipts, then gave me a clear breakdown of whether itemizing would benefit me, considering all factors including the car purchase. It identified some deductions I was missing too. Their system specifically flagged my vehicle purchase and explained exactly how the sales tax would apply in my situation.

•How does that work with TurboTax though? Do you still use TurboTax after using this service or does it replace tax software completely?

•That sounds like an ad. How much does it cost? And couldn't TurboTax do this calculation for you anyway? That's literally what tax software is for...

•You can still use TurboTax after using taxr.ai. What I did was get the analysis first which told me exactly what deductions to claim, then I entered that info into TurboTax with confidence. It's like having an expert review before you submit. The difference is that TurboTax asks you questions but doesn't analyze your receipts and documents directly, so you have to know what information to enter. With taxr.ai, it looks at your actual documents and identifies deductions you might miss. For me, it found some charitable donations I had forgotten about that helped push me over the standard deduction threshold.

I was skeptical about taxr.ai at first (seemed too good to be true), but I gave it a shot after struggling with this exact sales tax deduction question. I uploaded my car purchase agreement and a few other documents, and within hours got a detailed breakdown. Turns out I was actually better off taking the standard deduction despite my car purchase, which saved me from wasting time gathering all my receipts. What really surprised me was that it caught that my state has a vehicle property tax that IS deductible separately from the sales tax vs. income tax choice! So I still got some benefit from my car purchase even with the standard deduction. Would never have figured that out on my own, and TurboTax's questions didn't make that clear at all. Definitely using it again this year before I even open TurboTax.

If you're trying to get clarity directly from the IRS about this sales tax deduction, good luck getting through! I spent HOURS on hold last month trying to ask about a similar situation. Then I found Claimyr (https://claimyr.com) and watched their demo video (https://youtu.be/_kiP6q8DX5c). Basically, they get you to the front of the IRS phone queue so you can speak to an actual agent. I was able to talk directly with an IRS representative who explained exactly how the sales tax deduction works with my specific situation. They confirmed that for my state, the income tax deduction was better despite my major purchases. The agent also explained some nuances about the sales tax tables that the software wasn't clear about. Saved me hours of frustration and gave me definitive answers straight from the source.

•Wait, how does this actually work? Is this legit? I'm picturing some sketchy service that somehow hacks the IRS phone system lol

•This sounds like complete BS. There's no way to "skip the line" with the IRS unless you're paying for representation from a CPA or EA. I'd be very careful about services claiming to get you special treatment.

•It's completely legitimate. The service uses an automated system that navigates the IRS phone tree and waits on hold for you. When an agent finally picks up, you get a call connecting you to that agent. It's not "hacking" anything - just technology that waits on hold so you don't have to. They don't get you "special treatment" - you're just getting the same service any caller would, but without wasting hours of your life on hold. The IRS agents I spoke with were helpful and had no issue with how I reached them. It's basically like having someone wait in a physical line for you.

I need to eat my words about Claimyr. After posting my skeptical comment, I decided to try it myself since I had a question about home office deductions that I'd been unable to get answered. I figured it wouldn't work, but surprisingly, I got a call back in about 45 minutes connecting me to an actual IRS agent. The agent was incredibly helpful and even looked up my specific regional tax information to give me accurate guidance. She explained some nuances about home office deductions that I hadn't understood from the IRS website. For the original poster, I'd recommend using this service if you want definitive answers about your sales tax deduction question - the agent I spoke with immediately knew the rules around major purchase sales tax deductions and could provide state-specific guidance.

Just to add my 2 cents - I was in a similar situation last year with a boat purchase. The standard deduction for 2023 is pretty high ($27,700 for married filing jointly), so unless you have a lot of other itemized deductions, the sales tax from even a major purchase might not push you over that threshold. In my case, between mortgage interest (~$14,000), property taxes ($8,000), charitable donations ($3,000), and the sales tax from regular purchases plus my boat ($4,500), I was able to itemize and get about $2,500 more than the standard deduction. But it was close, and without the boat purchase, the standard deduction would have been better.

•Do you remember if TurboTax automatically calculated the regular sales tax amount for you based on your income, or did you have to figure that out separately? I'm trying to decide if it's even worth digging up my car purchase paperwork.

•TurboTax definitely calculates the regular sales tax amount automatically based on your income and location. You just need to provide the additional sales tax from major purchases. I'd recommend digging up the car paperwork because it only takes a minute to enter, and TurboTax will instantly tell you whether itemizing or taking the standard deduction is better. It won't change your standard deduction if that's better for you, but you might be surprised. In my case, it was the combination of all deductions that made itemizing worthwhile, and the boat sales tax pushed me over the edge.

Remember that sales tax deduction isn't the only benefit of a major vehicle purchase for taxes. If you bought an electric vehicle, you might qualify for the Clean Vehicle Credit (up to $7,500). Also, if you use your vehicle for business, you might be able to deduct mileage or actual expenses regardless of whether you itemize or take the standard deduction.

•Thanks for mentioning this! Mine isn't electric, but I do use it sometimes for my side gig driving for a food delivery app. I didn't even think about the business use angle. Does that mean I could potentially deduct the mileage for work trips AND still take the standard deduction?

•Yes! Business mileage is completely separate from your personal deductions. If you're using your car for food delivery, you can absolutely deduct the business portion of your vehicle expenses (usually using the standard mileage rate of 65.5 cents per mile for 2023) even while taking the standard deduction for your personal taxes. Just make sure you keep a good mileage log showing business vs. personal use. The IRS is picky about documentation for business vehicles. Apps like MileIQ or Everlance can make this much easier. This deduction would go on Schedule C for your delivery income, not on Schedule A where itemized deductions go, which is why you can take both.

Don't overlook state-specific rules either! Some states have different regulations about what qualifies for sales tax deductions. For example, in Texas there's no state income tax, so the sales tax deduction is almost always better than trying to deduct state income tax (which would be $0). But in high-tax states like California or New York, you'd need to run the numbers carefully. Also, if you're close to the itemization threshold, consider timing other deductible expenses. You might bunch charitable donations or pay property taxes early to push yourself over the standard deduction limit and make that car sales tax deduction worthwhile. TurboTax should walk you through this comparison, but it's worth understanding the strategy behind it. One more tip: keep that car purchase documentation forever. If you get audited, the IRS will want to see proof of the sales tax amount you claimed.

•This is really helpful about the state-specific rules! I'm in Ohio and we do have state income tax, so I'll need to compare carefully. The bunching strategy for charitable donations is interesting - I usually just donate throughout the year but hadn't thought about timing it strategically. Quick question about the documentation - should I keep the full car purchase agreement or just the sales tax portion? The paperwork is pretty thick and I want to make sure I'm keeping the right parts for potential audit purposes.

•For audit purposes, keep the entire purchase agreement - not just the sales tax portion. The IRS may want to verify the purchase date, amount, and that it was actually your purchase. The sales tax line item needs context from the full document. Regarding Ohio, you'll definitely want to compare your state income tax paid vs. the sales tax option. Ohio's income tax rates aren't as high as some states, so depending on your income level and that $2,800 car purchase, the sales tax route might actually work out better. The bunching strategy can be really effective - if you're close to itemizing, consider making January charitable donations in December instead, or prepaying property taxes if your locality allows it. This can help push you over the threshold to make all your itemized deductions (including that car sales tax) worthwhile.

Great question! I was in a similar situation last year with a major appliance purchase. The key thing to remember is that you can only choose ONE: either deduct state/local income taxes OR sales taxes - not both. For your car purchase, here's what you need to consider: TurboTax will calculate a base sales tax amount based on your income and state (this covers your regular purchases), then you add the $2,800 from your car on top of that. But this only helps if your TOTAL itemized deductions exceed the standard deduction ($13,850 single, $27,700 married filing jointly for 2023). Since you mentioned you just bought a house, you likely have mortgage interest and property taxes that could push you into itemizing territory. Let TurboTax run both scenarios - it'll show you the exact dollar difference. With a new house AND that car purchase, there's a good chance itemizing will be better for you. Don't forget to gather all your deductible expenses: mortgage interest, property taxes, charitable donations, and any medical expenses over 7.5% of your income. The sales tax deduction can definitely be worth it, especially in your situation with multiple major purchases in one year!

•This is such a helpful breakdown! I'm actually in a very similar situation - bought a house earlier this year and a car a few months later. I've been putting off dealing with taxes because all the deduction options seemed overwhelming, but your explanation makes it much clearer. One thing I'm wondering about - you mentioned medical expenses over 7.5% of income. Is that 7.5% of gross income or adjusted gross income? I had some unexpected dental work this year that was pretty expensive, and I'm trying to figure out if it's even worth tracking those receipts. Also, does dental work definitely count as a medical expense for tax purposes? The mortgage interest piece gives me hope that itemizing might actually work out. My loan is pretty new so most of my payments are going toward interest right now. Thanks for laying out all the different categories - I didn't realize there were so many potential deductions to consider beyond just the car sales tax!
