One thing that hasn't been mentioned yet - if you had to get any permits for your renovation work, those permit fees can definitely be added to your basis as they're directly related to the improvements. Same goes for any required inspections. Also, be careful about mixing renovation expenses with regular maintenance. For example, if you had to replace a broken window during renovation, that's maintenance/repair. But if you upgraded all the windows to energy-efficient ones as part of improving the property, those are capital improvements that increase your basis. The key test is whether the expense restores the property to its original condition (repair/maintenance) or makes it better than it was (improvement). For a flip, you're generally trying to improve the property beyond its original state, so most of your major expenses should qualify for basis treatment. Keep all your receipts organized by category - it'll make everything much easier come tax time!

Just want to add something that might help with organizing all these expenses - I created a simple spreadsheet with categories for each type of expense (materials, labor, permits, carrying costs like utilities/interest, etc.) and tracked everything weekly during my renovation. It really helped at tax time to have everything already sorted into the right buckets. I included columns for date, vendor, amount, category, and a brief description of what the expense was for. This made it super easy to separate true capital improvements from any maintenance items. One thing I learned the hard way - save digital copies of all receipts! I had a few paper receipts fade over the months, and trying to reconstruct those expenses was a nightmare. Taking photos of receipts right when you get them can save you major headaches later. Also, don't forget about any equipment you purchased specifically for the flip that you won't use again - things like specialty tools or a wet saw for tile work. Those costs can be added to your basis too since they were necessary for completing the improvements.

Just want to share that I made a mistake with this exact thing last year - entered my I-Bond interest in Box 1 of my state return and ended up paying state tax on it when I shouldn't have!!! Found out later that Treasury interest is state tax exempt. Called my state tax dept and had to file an amended return to get that money back. Don't make my mistake!!

This is such a helpful thread! I'm dealing with the same situation - got my first I-Bond 1099-INT this year and was totally confused why Box 1 was empty. Really appreciate everyone explaining that Box 3 is the right place for Treasury interest and that it's state tax exempt. One question I haven't seen addressed - if I bought I-Bonds throughout the year but only cashed some of them, will I get separate 1099-INTs for each redemption, or does Treasury consolidate everything into one form? I redeemed bonds in both June and November last year.

One important thing nobody's mentioned - if you take 529 distributions for your mortgage, you CANNOT also claim those same housing expenses for other education tax benefits like the Lifetime Learning Credit. That would be double-dipping and is definitely not allowed. Make sure you're maximizing your overall tax benefit by figuring out which approach saves you more in your specific situation!

Great point about not double-dipping with other education tax benefits! This is something I actually learned the hard way when my tax preparer caught it during review. I'd been planning to use 529 funds for my mortgage AND claim the Lifetime Learning Credit for my tuition, but you have to choose one path or the other for any overlapping expenses. In my case, the 529 withdrawal ended up being more beneficial since I could cover a larger portion of my housing costs tax-free, rather than getting a smaller credit. For anyone in this situation, I'd recommend running the numbers both ways before deciding. Sometimes the education credits might actually save you more money than the tax-free 529 withdrawal, especially if you're in a lower tax bracket. It really depends on your specific income level and how much you're planning to withdraw from the 529. Also worth noting - you can still use 529 funds for some expenses (like housing) and claim education credits for others (like tuition and fees), as long as you're not double-counting any single expense. Just keep very clear records of which expenses you're applying to which tax benefit!

I just take a picture of mixed receipts immediately and mark them up digitally using my phone's markup tools. Circle business items in red, add up the subtotal right on the image, and calculate the proportional tax. Then save to a tax folder in my cloud storage. My accountant said the IRS doesn't require original paper receipts anymore - digital copies are acceptable as long as they're legible and you can prove the expense was for business.

Great question! I've been dealing with this exact same issue as a freelance consultant. Here's what I've learned works best: For mixed receipts, definitely keep them - just be methodical about marking them up. I use a simple system: I circle all business items in blue ink and write "BIZ" next to each one, then total up just those items at the bottom of the receipt. This makes it crystal clear what portion was for business. For the sales tax calculation, the proportional method is totally acceptable. If your business items were $30 out of a $60 total purchase, then you can claim 50% of the sales tax ($6.43 out of your $12.85 example). The IRS just wants to see that you have a reasonable, consistent method. One tip that's saved me time: I do this markup immediately while I'm still in the parking lot or as soon as I get home. Trying to remember what was business vs personal weeks later is nearly impossible, especially for generic items like batteries or folders. Your spreadsheet approach sounds solid - just make sure you're only entering the business portion of each receipt, including the calculated business portion of sales tax. Keep those marked-up receipts organized by month in case you need them later!

For your situation with the inherited Colorado property, you'll definitely need to handle depreciation, but there are a few important considerations since it's inherited property. Your depreciable basis will be the fair market value at the time you inherited it (stepped-up basis), not what the previous owner paid. Since you're only renting one bedroom, you'll calculate the percentage that room represents of the total property (including reasonable allocation of common areas your tenant uses like kitchen, bathroom, hallways). Keep detailed records of your square footage calculations. One thing to watch out for - since you're keeping other rooms vacant for personal use when you visit, make sure you're not claiming any expenses for those areas. Only the portion actually available for rent can be depreciated and have expenses allocated to it. Also, don't forget you'll likely need to file a Colorado non-resident tax return for the rental income, in addition to reporting it on your Minnesota return. Colorado requires non-residents to file if they have any Colorado-source income, which rental income definitely qualifies as.

As someone who's dealt with similar inherited rental property situations, I want to emphasize a few key points that often get overlooked: First, since this is inherited property, make sure you get a proper appraisal or at least a CMA (Comparative Market Analysis) from a real estate agent to establish your stepped-up basis. This is crucial because it becomes your starting point for depreciation calculations. The IRS may ask for documentation of this value later. For the room rental calculation, I'd recommend using the "rooms method" in addition to square footage. Since you're renting 1 room out of 3 bedrooms, that's 33% just for the bedroom. Then add proportional common areas (kitchen, living room, bathrooms the tenant uses). This often gives you a more reasonable percentage than pure square footage alone. Don't forget about Colorado's specific rules for non-resident landlords. Colorado requires quarterly estimated tax payments if you expect to owe more than $1,000 in state tax. Also, Colorado has some unique deduction limitations for out-of-state owners that might affect your return. Keep meticulous records of everything - utility bills, maintenance, travel expenses to the property (these can be deductible), and any improvements. Since you're new to this, consider setting up a separate bank account just for the rental to keep finances clean. The fact that you're keeping rooms available for personal use actually works in your favor tax-wise - you're being conservative about what you're claiming as rental expenses, which the IRS appreciates.
