One thing to watch out for - make sure your state extension gets filed too! I filed my federal extension one year but completely forgot that my state needed a separate extension form. Ended up with a state penalty even though my federal was fine.
Omg thank you for mentioning this! I totally would have forgotten about the state part. Do you know if most CPAs automatically handle both the federal and state extensions when you ask them to file an extension?
Most CPAs will handle both federal and state extensions automatically if they know which state(s) you need to file in. It's part of their standard process, but it never hurts to specifically ask to make sure they're filing all necessary extensions. Always good to explicitly confirm they're handling both, especially if you have multi-state filing requirements or if you've recently moved. Different states have different rules about extensions too - some automatically grant the same extension as federal while others require their own form.
Just a quick tip - even though you're expecting a refund, if your calculations are off and you end up owing, you'll be charged interest from the April deadline, not from the extended October deadline. When I filed an extension in 2023, I estimated wrong and ended up owing $600... got hit with like $30 in interest because I waited until September to file!
One thing nobody's mentioned yet - check if you qualify for any deductions or credits you might have missed! At your income levels, you probably can't take full advantage of many credits, but you might still qualify for: - Mortgage interest deduction if you own a home - State and local tax deductions (capped at $10k) - HSA contributions if you have eligible health insurance - Student loan interest deduction (though this phases out at higher incomes) - Charitable contributions Even if it doesn't eliminate the whole bill, finding an extra thousand in deductions could help take the edge off! Just make sure whatever software you're using is checking for all possible deductions.
We do own a home, so I'll make sure the mortgage interest is included. I think we've got about $8k in state taxes too. Do you know if student loan interest is still deductible if we file MFS for the IDR benefits?
Unfortunately, one of the major downsides of filing MFS is that you cannot deduct student loan interest. This is one of several tax benefits you lose when filing separately. The student loan interest deduction starts phasing out at $75,000 for single filers and $155,000 for joint filers, and is eliminated completely at $90,000 and $185,000 respectively. You should definitely make sure you're capturing the mortgage interest and state/local taxes (SALT). Keep in mind that the standard deduction for MFJ is $27,700 for 2023, so your itemized deductions would need to exceed that amount to be worthwhile. For MFS, each of you would have a $13,850 standard deduction.
Don't forget to check your actual W-2s to make sure the withholding amounts look right! I had a situation where my employer messed up my withholding for half the year and that's why I ended up with a huge tax bill. Box 2 on both your W-2s should show federal income tax withheld. Add those numbers up and compare to what you're supposed to owe. If your total combined withholding is way less than $10k, that's definitely the problem. At your income levels (about $300k combined), your effective tax rate should be around 15-20% depending on deductions, so you should have had roughly $45-60k withheld throughout the year.
One tip nobody's mentioned - if you expect to make more than $400 in profit from your side business, you need to pay self-employment tax. Make sure you're setting aside roughly 30% of your profits for taxes (15.3% for self-employment tax plus your regular income tax rate). Also - keep ALL your receipts and track everything meticulously. I'd recommend a separate business bank account and credit card just for your side business expenses to make things super clear at tax time.
The 30% rule of thumb is helpful! Do you think it's worth using accounting software like QuickBooks Self-Employed at my income level, or is that overkill?
For your income level ($10-15K), I think a simple spreadsheet might be sufficient if you're organized, but QuickBooks Self-Employed is actually pretty reasonably priced and automates a lot. The time you save categorizing expenses and calculating quarterly taxes might be worth the subscription cost. What I like about dedicated accounting software is that it lets you snap photos of receipts on the go and automatically categorizes transactions. It also helps track mileage if you're driving for business purposes. Plus, when your business grows, you'll already have a system in place rather than trying to transition later.
Can someone explain how business mileage deductions work for a side business? I drive to clients sometimes but don't know if I can deduct that.
For 2025, you can deduct 67 cents per mile for business travel (the rate is adjusted annually). So if you drive 100 miles for business, that's a $67 deduction. You need to track your starting mileage, ending mileage, date, and business purpose for each trip. There are apps that can help track this automatically.
One thing nobody mentioned that REALLY helped my OIC get accepted - I included a detailed "special circumstances" letter explaining exactly why I couldn't pay and how my situation wouldn't improve in the foreseeable future. In my case, I had medical issues that limited my earning potential going forward, and I made sure to document this thoroughly. The IRS actually does consider effective tax administration and hardship cases if you provide compelling documentation. My OIC was accepted for about 15% of what I owed originally. Don't just fill out the forms - tell your story with documentation to back it up. It makes a huge difference.
Did you write this letter yourself or have a professional help you? I'm wondering if I should add something similar but I'm not sure how to structure it without sounding like I'm making excuses.
I wrote it myself, but I followed a clear structure. First paragraph explained the events that led to my tax debt (medical crisis + job loss). Second section outlined my current financial situation with specific numbers referenced from my 433-A form. Third part detailed why my situation was unlikely to improve (permanent disability affecting earning capacity). Last section expressed my good faith desire to resolve the debt while acknowledging my limitations. Keep it factual rather than emotional. Reference specific supporting documents you've included (medical records, disability determination, etc). I also had my accountant review it to make sure I wasn't saying anything that contradicted my financial statements. About 2 pages total - not too long, but enough to tell the complete story.
Watch out for timing issues with your OIC! If you're still in the 90-day review period, make sure you don't miss the deadline to appeal if they reject your offer. You only get 30 days to request an appeal, and if you miss that window, you have to start the whole process over again. Also, while your OIC is pending, the collection statute of limitations (usually 10 years) is paused. Just something to be aware of if your debt is already several years old.

Just FYI - even if you missed the window to amend your 2018-2019 returns, current homeowners should keep an eye on this deduction. Congress has extended it several times in the past, and there's always a possibility they'll reinstate it again for future tax years. I make a habit of checking every January to see what deductions have been extended. The mortgage insurance premium deduction can be worth hundreds of dollars if you itemize.

ā¢Do you know any good resources to keep track of these changing tax provisions? I always seem to find out about extensions after I've already filed.

ā¢I usually check the IRS website directly in January before tax season starts. They publish updates on extended provisions. The other resource I've found helpful is following the IRS newsroom (https://www.irs.gov/newsroom) which announces major tax law changes. Tax software usually updates quickly too, but if you file early in the season, sometimes they haven't incorporated the latest extensions that Congress passes at the last minute. That's why I generally wait until at least mid-February to file if I think I might benefit from typically extended provisions like the mortgage insurance premium deduction.

Anyone know if PMI on a refinanced mortgage qualifies for this deduction? I refinanced in 2018 and had to keep paying PMI even though I only pulled out a small amount of extra cash.

ā¢Yes, PMI on a refinanced mortgage would qualify for the deduction in 2018-2019, as long as the loan was primarily for home acquisition debt (buying, building, or substantially improving your home). If you took out some cash but it was minor compared to the refinance amount, the PMI should still be deductible. The key factor is that the insurance contract needed to be issued after 2006 and the loan had to be for your primary or second home, not an investment property.
