Landscaping business owner - do I need to report cost of goods sold on tax forms?
Hi all, I started my own landscaping business back in April and I'm trying to get a head start on my tax paperwork for next year. First time filing as self-employed and I'm confused about this whole cost of goods sold (COGS) thing. I mainly do lawn maintenance, some garden design, and small hardscaping projects. I buy plants, mulch, fertilizer, and sometimes pavers for clients. Do I need to report all this as COGS or can I just list them as regular business expenses? I'm using the Schedule C but the COGS section is confusing me. Also wondering if I should be tracking my inventory differently if I have leftover materials. Any help from people who've done this before would be super appreciated!

For landscaping businesses, the question of COGS vs. regular business expenses often depends on your specific operations. Generally, materials that become part of the permanent landscape (plants, mulch, pavers) would be considered COGS because they're directly tied to creating your "product." Equipment and supplies used across multiple jobs (mowers, trimmers, fuel) are typically regular business expenses. The key difference is whether the item becomes part of what the customer is buying. If you're purchasing plants specifically for a client's property, that's COGS. If you're buying gas for your equipment, that's a regular expense. For inventory tracking, if you regularly keep materials on hand between jobs, tracking inventory makes sense. Calculate beginning inventory + purchases - ending inventory to get your COGS for the year. But if you mostly buy materials job-by-job with minimal leftovers, a simpler tracking system might work fine.

•So if I buy bulk mulch that gets used across multiple jobs throughout the season, how do I determine what's COGS vs just an expense? Do I need to track exactly how much mulch went to each property? Seems like a bookkeeping nightmare!

•For bulk materials like mulch used across multiple jobs, you'd generally still consider that COGS - it's just a matter of tracking. You don't necessarily need to measure exactly how much mulch went to each specific property (though job costing can be helpful for pricing). For tax purposes, what matters is tracking your total inventory. At year end, count what's left and that becomes your "ending inventory." The formula is simple: Beginning inventory + Purchases - Ending inventory = COGS for the year. This gives you an accurate reflection of materials actually used in your services.

I was in the exact same boat as you last year with my landscaping side hustle. The COGS stuff was driving me nuts until I found https://taxr.ai which literally saved my sanity. I uploaded my messy spreadsheets and receipts and it sorted everything into the right categories automatically. It flagged all my plant purchases as COGS but kept my equipment maintenance as regular expenses. What really helped was that it explained WHY each item belonged in different categories, which helped me understand the whole system better. I ended up getting a much bigger deduction than I expected because I was categorizing things all wrong before.

•Does it work with QuickBooks or do I have to start from scratch? I've been using QB but I'm pretty sure I've been categorizing everything wrong.

•I'm skeptical about these tax tools. How does it know the specific rules for landscaping businesses? Seems like every industry has different COGS rules.

•It integrates with QuickBooks perfectly - you can import everything you've already done and it'll help recategorize items that might be misclassified. It took me about 15 minutes to connect and review everything. For industry-specific rules, that's actually where it shines. It has specific guidance for landscaping, construction, retail, and tons of other businesses. For example, it knows that in landscaping, plants installed are COGS but your mower depreciation isn't. It'll explain each category based on IRS guidelines for your specific business type.

Just wanted to update that I tried taxr.ai after seeing it mentioned here and wow - it was exactly what I needed. I had been categorizing ALL my expenses as "supplies" in QuickBooks (big mistake). The tool identified my plant purchases, hardscaping materials, and soil amendments as COGS, while keeping my truck expenses, equipment repairs, and insurance as standard deductions. The best part was the explanation feature that showed me exactly which line on Schedule C each expense should go. Turns out I was leaving money on the table by not properly tracking inventory from year to year. I'm now setting up a simple system to count leftover materials in December so I can properly calculate COGS for next year's taxes.

If you're spending hours trying to categorize expenses and figure out COGS, you might also be wasting time trying to call the IRS for clarification. I spent THREE DAYS trying to get through to ask about this exact issue. Finally used https://claimyr.com and got a callback from the IRS in less than 2 hours. You can see how it works here: https://youtu.be/_kiP6q8DX5c The IRS agent confirmed that for landscaping, plants and materials that become part of the landscape are indeed COGS, but also emphasized that consistent application is more important than perfect categorization for small operations. Got way more helpful info in 20 minutes than days of Googling.

•Wait, this actually works? I thought it was impossible to get through to the IRS these days. How much does this service cost?

•This sounds like BS honestly. The IRS has massive backlogs and can barely answer their own phones. How could some third-party service magically get through when millions of people can't?

•Yes, it actually works! The service basically holds your place in line and calls you when an agent is available, so you don't have to sit on hold for hours. I was surprised too, but it saved me from listening to that awful hold music all day. Regarding skepticism - totally get it. I was suspicious too. From what I understand, they use technology that continuously redials and navigates the IRS phone tree automatically until it gets through, then it connects you. Not magic, just automated persistence that we don't have time for as business owners.

Well I'm eating my words now. After being super skeptical about Claimyr, I tried it out of desperation because I had a similar COGS question specifically about inventory valuation methods for my landscaping materials. Got a callback from the IRS in about 90 minutes. The agent walked me through exactly how to handle leftover inventory and which form lines to use. She confirmed that for a small landscaping operation, I could use a simplified COGS approach until my business inventory exceeds certain thresholds. What's crazy is I'd been trying to get this answer for WEEKS. Would have saved me so much stress to just do this first instead of falling down internet rabbit holes.

One thing nobody mentioned yet - if you're just starting out in landscaping and your annual gross receipts are under $25 million (which I'm guessing they are lol), you might qualify for simplified accounting methods. This means you can potentially treat all your materials as regular expenses in the year you buy them instead of dealing with inventory and COGS. Check out the "small business taxpayer" exemptions. Saved me tons of headaches with my small landscaping business. You still need good records of everything, but the paperwork is way simpler.

•Wait really? That would be amazing if true! How do I know if I qualify for this exemption? Is there some form I need to file?

•You need to meet the gross receipts test - basically your average annual gross receipts for the past 3 tax years needs to be $25 million or less. For new businesses like yours, you just use the years you've been in business. There's no separate form to file for the exemption. You simply adopt the accounting method on your first Schedule C. There's a checkbox in Part III of Schedule C where you indicate your accounting method - you'd select "Cash" instead of "Accrual." This tells the IRS you're using the simplified method. Just be consistent with this method in future years.

Just a practical tip from someone who's been running a landscaping business for 8 years - get a dedicated app to track your inventory and job costs. I use GreenThumb (not the actual name but something similar) and it's made tax time sooooo much easier. You can scan receipts, assign materials to jobs, and it generates reports showing exactly what's COGS vs regular expenses. It even tracks your leftovers at the end of the season. PLUS it has templates specifically for landscaping businesses so you're not trying to adapt some general accounting software to fit your needs.

As someone who just went through this exact same confusion with my first year of self-employment, I totally feel your pain! The COGS vs regular expense distinction was driving me crazy too. Here's what I learned after talking to my accountant: if you're buying materials that physically become part of the customer's property (plants, mulch, pavers, etc.), those are COGS. But things like your truck expenses, equipment maintenance, and general supplies are regular business expenses. For tracking leftovers, I started doing a simple inventory count at the end of each month. Just walk around your storage area and estimate what you have left. You don't need to be super precise - even rough estimates work for tax purposes. I use a simple spreadsheet with columns for "material type," "estimated quantity," and "approximate value." One thing that really helped me was setting up separate storage areas for "job-specific" materials (stuff I bought for a particular client) versus "general inventory" (bulk materials I use across multiple jobs). Makes the year-end counting much easier! The Schedule C COGS section is definitely confusing at first, but once you get the hang of the basic formula (beginning inventory + purchases - ending inventory), it becomes pretty straightforward. Good luck with your first year of taxes!

•This is super helpful! I love the idea of separating job-specific materials from general inventory - that makes so much sense. Quick question about the monthly inventory counts though - do you physically weigh/measure everything or just do visual estimates? I'm worried about being too inaccurate for the IRS but also don't want to spend hours every month with a scale and measuring tape!

I've been doing landscaping for about 3 years now and went through this same learning curve! One thing that helped me a lot was keeping it simple in the beginning - don't overthink it too much your first year. Here's my practical approach: I keep all receipts in two folders - "Materials for Jobs" (plants, mulch, pavers, soil amendments) and "Business Operations" (gas, equipment repairs, insurance, tools). The first folder is basically your COGS, the second is regular expenses. For inventory, I do a quick count/estimate at the end of December. I don't get super precise - I'll count bags of mulch, estimate cubic yards of soil, count flats of leftover plants. The IRS isn't expecting you to weigh every ounce, they just want reasonable estimates that you can support if asked. Pro tip: take photos of your end-of-year inventory! It helps you remember what you had and provides backup documentation. I learned this the hard way when I couldn't remember if I had 15 or 25 bags of mulch left over. Also, since you're new to self-employment, make sure you're setting aside money for quarterly estimated taxes. That caught me off guard my first year way more than the COGS stuff did!

•The photo inventory tip is brilliant! I never would have thought of that but it makes perfect sense - especially for someone like me who tends to forget details. Do you take the photos with any specific app or just regular phone camera? Also really appreciate the heads up about quarterly taxes - I've been so focused on the COGS confusion that I haven't even started thinking about estimated payments yet. Did you use any particular method to calculate how much to set aside each quarter, or just wing it based on projected income?

•Just regular phone camera works fine! I organize them in a folder called "Year-End Inventory" with the date. Nothing fancy needed. For quarterly taxes, I use the "safe harbor" rule - if you pay 100% of last year's tax liability (or 110% if you made over $150k), you won't owe penalties even if you underpay. Since you're just starting out, you might not have a "last year" to reference, so a good rule of thumb is to set aside about 25-30% of your profit for taxes. I learned to transfer that money to a separate "tax savings" account immediately after each job so I'm not tempted to spend it. The IRS has a quarterly payment calculator on their website that's actually pretty helpful once you get a feel for your income patterns. But honestly, even rough estimates are better than nothing - you can always adjust as you go!

Hey Yuki! Welcome to the self-employed club - it's definitely a learning curve but you're asking all the right questions early on. I run a small property maintenance business and dealt with this exact same confusion my first year. Here's what I wish someone had told me: the key is whether the materials become part of what the customer is paying for. Plants you install = COGS. Fertilizer you apply = COGS. Gas for your mower = regular business expense. For tracking leftovers, I started super simple - just a notebook where I jot down what's left at year-end. Don't overthink it! You can always get more sophisticated as your business grows. One thing that really helped me was thinking about it this way: if a customer calls and asks "what am I paying for exactly?" - the materials they'd expect to see itemized (plants, mulch, pavers) are usually your COGS. The behind-the-scenes stuff (your truck payment, equipment maintenance) are regular expenses. Since you're just starting out and likely under that $25M threshold mentioned earlier, you might even qualify for simplified accounting methods that make this whole process way easier. Definitely worth looking into! Good luck with your first tax season - it gets much easier after you do it once!

•This is such a helpful way to think about it! The "what am I paying for exactly?" test makes so much more sense than trying to memorize complex rules. I've been overthinking this whole thing when really it comes down to what the customer would expect to see itemized versus what they assume is included in my service. Your point about starting simple with just a notebook is reassuring too - I was getting overwhelmed thinking I needed some fancy inventory system right away. Thanks for the encouragement about it getting easier! As a newcomer to both landscaping and self-employment, it's nice to hear from people who've successfully navigated this transition.
