I found my CSED by calling the Practitioner Priority Line through my accountant. If you have a tax professional, they can often get this information much faster than you can on your own. They read off all my CSED dates for different tax years right away. It's worth the money to have a pro handle this if you're dealing with significant tax debt.

I've been dealing with this exact same issue for months! What finally worked for me was requesting Form 4340 (Certificate of Assessments and Payments) directly from the IRS. This form explicitly shows your CSED dates for each tax year, unlike the regular transcripts that make you hunt for assessment dates and do the math yourself. You can request it by calling the IRS or by submitting Form 4506-T and specifically asking for Form 4340 in the remarks section. It takes about 10 business days to receive, but it's worth it because it removes all the guesswork. The form clearly lists "Collection Statute Expiration Date" for each liability, so there's no confusion about calculating 10 years from various transaction codes. Just be aware that if you've had any collection suspensions (bankruptcy, OIC, CDP hearings, etc.), those will extend your CSED beyond the basic 10-year period. But at least with Form 4340, you'll have the baseline dates to work from.

Has anyone actually dealt with fixing a W-9 that was already submitted when it should have been a W-8BEN? My university department did this to me last semester and I'm worried about tax season coming up.

Just wanted to add something important that might help - make sure you check with your university's international student office about work authorization before proceeding with any contractor arrangement. Even if you fix the tax forms (W-8BEN vs W-9), F-1 students have strict limitations on where and how they can work. Generally, F-1 students can only work on-campus during their first year, and off-campus work usually requires specific authorization like CPT (Curricular Practical Training) or OPT (Optional Practical Training). Working as an independent contractor for a startup without proper work authorization could violate your visa status, which is much more serious than tax form issues. I'd recommend getting clarity on your work authorization status first, then dealing with the tax classification. Your international student office should be able to help you understand what type of work authorization you need for this arrangement, if any. Don't assume that being paid as a contractor somehow changes the work authorization requirements - the visa regulations look at the actual work being performed, not how you're classified for tax purposes.

dont forget that for 2025 taxes the SALT deduction is still limited to $10k which means a lot of ppl with big mortgages dont even get to use their full mortgage interest deduction anyway! I've got like $24k in property taxes and state income tax but can only deduct $10k of it which sucks.

As someone who's dealt with multiple rental properties for years, I want to emphasize something that might get overlooked in all this discussion about the $750k limit and reporting requirements. Make sure you're also considering the timing of when you acquired each property and what the debt limits were at that time. If you took out your primary residence mortgage before December 15, 2017, you might actually be grandfathered under the old $1 million limit rather than the current $750k limit. This could significantly change your calculations, especially since your primary residence is around $820k. The grandfathering rules are complex but could save you thousands if you qualify. Also, since you mentioned this is your first year with the inherited rental property, don't forget that you may have gotten a stepped-up basis on that property when you inherited it. This could affect your depreciation calculations on Schedule E, which is separate from but related to your mortgage interest treatment. I'd strongly recommend consulting with a tax professional who specializes in real estate, especially for your first year handling multiple properties. The potential tax savings from proper planning usually far exceed the cost of professional advice.

Has anyone successfully requested a "retroactive" corrective distribution in the year after the overcontribution? I'm in almost the identical situation (overcontributed about $600) and wondering if I have options in the new year if my employer won't help now.

I went through this exact same situation last year - overcontributed by about $700 across two employers and hit the same wall with HR being unhelpful. Here's what I learned after sorting it all out: You're correct about the double taxation, but there are a couple of key details to get right. You'll need to file Form 5329 to report the excess contribution and pay the 6% excise tax. However, you can avoid the recurring 6% penalty in future years by reducing your 2025 contributions by the excess amount ($550). This essentially "applies" your 2024 excess to your 2025 limit. One thing I wish I had known earlier - if your current employer's plan administrator is different from HR, try contacting them directly with a formal written request. Sometimes the plan administrators are more knowledgeable about corrective distributions than the HR department. Include specific references to IRS regulations (like Revenue Procedure 2019-19) in your request. Also, double-check that you're actually over the limit when combining both employers. The 2024 limit was $23,000, and if there were any employer matching contributions, those don't count toward your personal contribution limit. If all else fails and you do end up paying the penalty, make sure to keep detailed records of the excess amount and the taxes paid. You'll need this documentation when you eventually withdraw those funds in retirement to avoid being double-taxed on the entire amount.

You might consider adjusting both your W4s rather than putting all the extra withholding on one person. My husband and I found it easier on our monthly budget to split the extra withholding between us rather than having one person's paycheck take the full hit. Also, check if either of your employers offer any tax planning resources. My company provides free access to financial advisors who helped us optimize our tax situation beyond just W4 withholding.

Your $812 extra withholding calculation sounds about right for your income situation. With combined income of $275k, you're likely hitting the 24% or even 32% tax bracket on the higher portions of your income, but each employer's withholding system assumes their job is your only income source. Here's what's happening: when employers withhold taxes, they use tables that assume that specific job is your only income. So your wife's employer withholds as if she's making $158k total, and your employer withholds as if you're making $117k total. But your actual tax liability is based on $275k combined income, which pushes you into higher brackets. The $812 per paycheck works out to about $21k annually in extra withholding, which could very well be the difference between what your employers naturally withhold versus your actual tax liability at that income level. You absolutely can split this between both your W4s - it doesn't matter to the IRS which employer withholds the extra amount. If cash flow is a concern, splitting it might make more sense for your budget. Just make sure the total extra withholding across both jobs equals what the calculator recommended. I'd also suggest running a quick sanity check by estimating your total tax liability for the year and comparing it to what would be withheld without the extra amount. That difference should be close to your calculated extra withholding.
