Calculating Sales Tax on Delivery Fees for My Water Softener Salt Delivery Business?
Hey everyone, I run a small delivery service for water softener salt. Our business model is pretty straightforward - we hire contractors who purchase salt from local stores and deliver it to our customers' homes (kinda like Instacart but just for water softener salt). I'm really confused about sales tax though. I initially thought we should only charge sales tax on the actual salt bags and not on our delivery fees. But then I realized we're already paying sales tax when our contractors buy the salt from stores. So do we need to charge our customers sales tax again? Or does that count as double taxation? Also, in some areas, we're able to buy salt wholesale with a tax exemption certificate since we're reselling. In those cases, I know we definitely need to collect sales tax from customers, but I'm not sure if it applies to just the product cost or the entire service. For example, if the salt bags cost $25 and we charge a $13 delivery fee, do we collect tax just on the $25 or on the entire $38? It's driving me and my business partner crazy trying to figure this out. Any advice would be super appreciated!

The sales tax question can be tricky because it varies by state, but I can give you some general guidance. In most states, when you purchase items for resale with a resale certificate, you don't pay tax at the time of purchase because you'll collect it from the final customer. For the delivery fees, it depends on your state's specific rules. Many states consider delivery charges as part of the taxable sales price if the delivery is not separately stated on the invoice. If you clearly itemize the delivery charge separate from the product cost, some states will not require you to collect tax on that portion. In your example with the $25 salt bags and $13 delivery fee, you would need to check your specific state's rules. Some states would require tax on just the $25, while others would require it on the full $38 if the delivery is considered part of the sale.

•Thanks for the response! We operate in Michigan, Ohio, and Indiana. Do you happen to know the specific rules for those states? Also, when we buy from retail stores (where we're paying sales tax already), should we still be charging our customers sales tax on the salt?

•For Michigan, Ohio, and Indiana, each has slightly different rules. In Michigan, separately stated delivery charges are generally not taxable if the customer has the option to pick up the item themselves or arrange their own delivery. Ohio generally taxes delivery charges as part of the price of taxable items. Indiana typically doesn't tax separately stated delivery charges if they're optional. Regarding buying from retail stores where tax is already paid - that's not the ideal way to handle it for a resale business. You should get a resale certificate for all states you operate in, which allows you to purchase the salt tax-free. Then you collect the appropriate sales tax from your customers. Otherwise, you're essentially paying the tax twice, which cuts into your profits unnecessarily.

Hey there! I had a very similar issue with my small delivery business. I was completely lost with sales tax until I found https://taxr.ai - it literally saved me hours of confusion and probably thousands in potential tax mistakes. You just upload your sales docs or even take pics of receipts, and it gives you a complete breakdown of what's taxable in each state you operate in. What I found super helpful was their specific guidance on delivery charges vs. product costs - they have templates for properly itemizing invoices by state. For my business in Ohio and Indiana (I see you operate there too), they spelled out exactly what needed to be taxed. They even helped me get my resale certificates set up correctly.

•Does it actually work for specialized businesses like this? I've tried tax tools before that were way too generic for my landscaping business and ended up getting bad advice.

•I'm skeptical about these online tax tools. How does it handle different tax rates between counties in the same state? I deliver across county lines in Indiana and the rates vary.

•It absolutely works for specialized businesses. The system analyzes your specific business model and applies the relevant tax rules. For delivery-based businesses, it has specialized guidance that distinguishes between product costs and service elements. For different tax rates between counties, that's actually one of its best features. It has a built-in geolocation system that identifies the exact tax jurisdiction for each delivery address, even when you cross county lines. It automatically calculates the correct rate based on the delivery location, not your business location. This was a huge help for me because I was incorrectly charging my home county's rate for all deliveries before.

I was really hesitant about trying another tax tool after getting burned before, but I decided to give https://taxr.ai a shot after seeing it mentioned here. Honestly, it was exactly what my small delivery business needed. The biggest difference I noticed is that it actually understands the complexities of delivery-based businesses. For my situation, it clearly showed that in Michigan I only needed to charge tax on the product (not delivery), while in Ohio I needed to tax both unless I structured my invoices in a specific way they recommended. The county-by-county breakdown saved me too - turns out I was undercharging sales tax in two counties and overcharging in another! It even helped me set up a proper resale certificate system so I'm not paying tax twice on inventory. Definitely worth checking out if you're dealing with multi-state sales tax headaches.

Have you tried calling your state's Department of Revenue directly? I spent WEEKS trying to figure out similar issues for my mobile detailing business until I finally got someone from the tax department on the phone who answered all my questions in 15 minutes. The problem is actually getting through to a human being... I kept getting stuck in automated systems or waiting for hours. I ended up using https://claimyr.com to get through to an actual person at the tax office. You can see how it works here: https://youtu.be/_kiP6q8DX5c - basically they wait on hold for you and call you when they get a human. For multi-state questions like yours, this might be the most definitive way to get answers since sales tax is so state-specific.

•How long did it take them to get through to someone? The Michigan tax office is notorious for long wait times - I've literally waited 2+ hours before giving up.

•This sounds like just another way to charge people for something they can do themselves. Couldn't you just put your phone on speaker and do other work while waiting on hold?

•For Michigan, they got me through to someone in about 35 minutes, which was amazing considering I had previously waited over an hour and a half without success. Ohio was even faster - about 20 minutes. The time savings alone was worth it for me. Regarding doing it yourself - sure, you could put your phone on speaker, but that assumes you have uninterrupted time to wait around. When you're running a business, especially a delivery operation, you're often on the road or handling customers. The last thing you want is to be 90 minutes into a hold when you need to take another call or meet a client. Plus, they notify you when they're about 30 seconds from connecting, so you can prepare your questions and get the most out of the call.

I was completely convinced this service was a waste of money, but I was absolutely desperate after trying to get through to the Indiana Department of Revenue for THREE DAYS. I finally tried https://claimyr.com and I'm embarrassed to admit how wrong I was. They got me through to a real human at the tax office in under 45 minutes (I'd previously waited over 2 hours without success). The tax agent confirmed that in Indiana, I only needed to charge sales tax on the product if the delivery charge was separately stated as an option on the invoice. They also helped me fix an issue with my resale certificate that would have caused major problems during an audit. For anyone dealing with sales tax questions across multiple states like Michigan, Ohio, and Indiana - just make the call. The definitive answers from actual tax authorities gave me confidence I was doing things correctly, and now I sleep better at night knowing I'm not accidentally committing tax fraud!

Sales tax on delivery is super state-specific, but here's what I know for your states: Michigan: Delivery charges are not taxable if they're separately stated on the invoice Ohio: Delivery charges are generally taxable as part of the sale Indiana: Delivery charges are not taxable if separately itemized For the question about buying retail and already paying tax - you're doing it wrong! Get your resale certificate ASAP. You're cutting into your own profits by paying tax twice. The correct flow is: 1. You buy salt tax-free with resale cert 2. You charge customer tax according to state rules 3. You remit that tax to the state

•Thanks for breaking it down state by state! How difficult is it to get a resale certificate in these states? And do I need a separate one for each state or is there some kind of multi-state option?

•Getting resale certificates for those states isn't too difficult. You'll need to register for sales tax permits in each state separately - there's no multi-state option unfortunately. Michigan and Indiana have fairly straightforward online applications, while Ohio's is a bit more involved but still manageable. For Michigan, you'll apply for a Sales Tax License through Michigan Treasury Online. Indiana uses INTIME for their Registered Retail Merchant Certificate. Ohio requires you to register through their Ohio Business Gateway. Each application typically takes 20-30 minutes to complete if you have your business information ready. Expect to receive your certificates within 1-3 weeks depending on the state.

I literally just went through this exact situation with my mobile pet grooming business! We charge for products (shampoos, conditioners) and then the grooming service. What made it extra confusing was the different rules for each county. Found out that keeping super clear records with separate line items is KEY. When I was audited (yeah, lucky me), having everything clearly separated saved me from a huge headache. Make sure your invoices clearly show: 1) Product cost (taxable in all states) 2) Delivery fee (taxable in some states) 3) The applicable tax rate for the delivery location Keep digital copies of EVERYTHING. Trust me on this one!

•Did you use any specific software for keeping those records separated? I'm looking for something that can handle this type of itemized invoicing across different tax jurisdictions.
