This is incredibly helpful information! I had no idea that the filing order could make such a big difference. When you mention filing them simultaneously vs in reverse order - could you elaborate on what the best approach would be for someone in the OP's situation with a 2017 overpayment and 2018 underpayment? Also, you mentioned estimated tax payments for 2019 potentially being applied back to 2018 - how does that work exactly? I thought estimated payments could only be applied to the year they were intended for. Is there a specific form or process to request that kind of reallocation? I'm dealing with a similar mess (2016-2018 unfiled) and trying to figure out the optimal strategy before I make any costly mistakes. Your point about professional review is well taken - do you have any recommendations for finding someone who specializes in multi-year filing situations like this?

Great question about filing strategy! For the OP's situation (2017 overpayment, 2018 underpayment), the optimal approach would typically be to file both returns simultaneously in separate envelopes but mailed on the same day. On the 2017 return, you'd check the box to apply the overpayment to the following year rather than requesting a refund. This creates a clean paper trail showing your intent. Regarding estimated payments - yes, you can request reallocation! If you made estimated payments for 2019 but later determine you owed more for 2018, you can file Form 843 (Claim for Refund and Request for Abatement) to request those payments be moved back. The IRS has some flexibility here, especially when dealing with unfiled returns being caught up. For finding the right professional, look for an Enrolled Agent (EA) who specifically advertises experience with "back tax resolution" or "unfiled returns." They're often more cost-effective than CPAs for this type of work and have specialized training in IRS procedures. Many offer free consultations where they can review your specific situation and give you a filing strategy upfront. The key is finding someone who won't just prepare the returns but will analyze the optimal approach for your multi-year situation first.

This is such valuable advice about acting quickly! I'm actually in this exact situation right now - discovered I have unfiled returns from 2017-2019 about six months ago and I've been paralyzed by all the conflicting information I've found online. Your point about creating a spreadsheet is brilliant - I keep getting overwhelmed trying to figure out what I owe vs what I paid in my head. Did you include estimated quarterly payments in your tracking as well? I made payments for some quarters but not others, and I'm not even sure which years they were applied to. The 60% recovery rate you mentioned gives me hope. I was starting to think I'd lost everything to the statute of limitations. When you say "strategic filing order," do you mean you filed the earliest year first, or did you file them in reverse chronological order? I keep seeing conflicting advice on this. Also, did you handle the filings yourself or work with a professional? I'm trying to decide if the cost of professional help is worth it given that I'm already facing penalties and interest charges.

This is really helpful advice! I'm just starting to think about taking on a second job myself and hadn't even considered the tip income aspect. Quick question - when you mention keeping records of work-related expenses from restaurant work, what kinds of things typically qualify? I know the tax laws changed a few years back for employee deductions. Are there still legitimate deductions for restaurant workers, or is it mainly just important for tracking purposes?

You're absolutely right to ask about this! Unfortunately, since the 2018 Tax Cuts and Jobs Act, most unreimbursed employee expenses (including things like uniforms, non-slip shoes, or tools) are no longer deductible for W-2 employees. The tracking is mainly important now for tip income reporting and making sure your employer is properly withholding on declared tips. However, if you end up doing any delivery work as part of the restaurant job and use your personal vehicle, that could potentially be deductible if you're treated as an independent contractor rather than an employee. The key is understanding your employment classification - W-2 employee vs 1099 contractor makes a big difference for deductions. For most traditional restaurant employee roles though, the focus should really be on proper withholding and tip reporting rather than trying to find deductions. The withholding planning @Ravi mentioned is definitely where you'll get the most benefit!

This is such solid advice, especially about the emergency fund for tax surprises! I never thought about how low the tipped minimum wage could affect withholding. Quick question - when you mention the W-4 checkbox for multiple jobs, do both employers need to know, or is it enough to just check it on one job's form? I want to make sure I'm handling this correctly from day one. Also, your point about being conservative with withholding really resonates. I'd much rather get a refund than scramble to pay a big tax bill when I'm trying to save for a house. Better safe than sorry!

Great question about the W-4 checkbox! Technically, you should check the multiple jobs box on both employers' W-4 forms for the most accurate withholding calculations. The IRS designed the form so that when both employers know about your multiple job situation, their payroll systems can coordinate better to avoid under-withholding. However, in practice, many people find it easier to just handle the extra withholding through their primary job (like adjusting line 4c for additional withholding) rather than trying to coordinate between two different HR departments. The key is making sure the total amount of tax withheld across both jobs covers your liability. Your instinct about being conservative is spot-on! When I was house shopping, I actually increased my withholding even more than the calculators suggested because I knew I couldn't afford any surprises. It meant smaller paychecks during the year, but having that peace of mind (and getting a nice refund right around house-hunting season) was totally worth it. You're already thinking about this the right way!

It's not really about taxing more people - it's about closing a reporting gap. People who earn income through these platforms SHOULD be paying taxes, just like income from any other source. The problem is the implementation is causing confusion between actual income vs. personal transfers. What they should've done is create clearer guidelines and better education before implementing the lower threshold. The apps themselves have been improving their systems to help distinguish personal from business transactions, which helps.

This is really helpful, thank you! I think I'm in a similar boat - most of my transactions are sending money TO friends rather than receiving it. But I did sell a few things on Facebook Marketplace this year. One question - how do I prove what I originally paid for something if I don't have the receipt anymore? Like I sold my old gaming console for $180 but I bought it like 3 years ago and definitely don't have that receipt. Can I just estimate based on what it cost new at the time, or do I need actual documentation? Also, when you say "keep screenshots" - do you mean of the actual Venmo/CashApp transactions, or something else? I want to make sure I'm documenting the right stuff in case I do get audited later.

That's really smart advice about timing and running it twice a year! I never thought about waiting for multiple paystubs before using the calculator. I've been making the mistake of trying to use it right after New Year's with just one paystub, which probably explains why my estimates seemed off. Do you have a specific month you prefer for your spring and fall check-ins, or do you just go by when major life changes happen?

@Jordan Walker I usually do my spring check around late March/early April before (the tax deadline so I can still make estimated payments if needed and) my fall check in September or October. Those timing windows work well because by spring you have a good chunk of the year s'data, and fall gives you time to adjust your W-4 for the last few months if needed. The key is having enough paystubs to see patterns - like if your overtime varies seasonally or if annual bonuses affect your withholding calculations. I learned this the hard way after using just one January paystub and ending up way off on my projections!

This is such a helpful clarification! I think I've been making the same mistake with my paystub. Mine shows "gross earnings," "adjusted gross," and "taxable wages" and I was never sure which one to use. So you're saying I should use the very first number that shows my total pay before ANY deductions at all? That would be way higher than what I've been entering. No wonder the calculator kept telling me I was under-withholding - I was probably inputting a much lower number than my actual gross income!

I filed an SS-8 in early 2023 and finally got my determination in November - so about 9 months. The IRS ruled in my favor and determined I was an employee. My former "client" had to pay back taxes, and I got a refund for the excess self-employment tax I had paid. The process was definitely slow but totally worth it in my case since I got back around $4500. I used code G on Form 8919 when I initially filed my taxes, so I only paid the employee portion while waiting for the determination.

This is such valuable advice! I'm actually in the exact same boat as the original poster and had no idea about using code G on Form 8919 when filing with SS-8 simultaneously. That detail about only paying 7.65% vs 15.3% while waiting for determination could save me thousands. One question - if I file the 8919 with code G and later the SS-8 determination goes against me (saying I really was an independent contractor), would I then owe the difference in self-employment taxes plus penalties? Or is there some protection for good faith filings based on reasonable belief of misclassification? Also, has anyone had success getting their former employers to voluntarily correct the classification before going through the formal SS-8 process? I'm wondering if showing them the potential penalties might motivate them to issue corrected W-2s instead.

Great question about the potential consequences if the SS-8 determination goes against you. From what I understand, if the IRS ultimately rules that you were properly classified as an independent contractor, you would indeed owe the difference between what you paid (employee portion at 7.65%) and what you should have paid (full self-employment tax at 15.3%). However, there typically aren't penalties for good faith filings when you have a reasonable basis for believing you were misclassified. The key is having solid documentation to support your position - things like emails showing they controlled your schedule, evidence you used their equipment, lack of ability to work for competitors, etc. The IRS looks at the totality of the working relationship. As for getting employers to voluntarily correct - I've seen it happen but it's pretty rare. Most employers resist because they'd have to pay their portion of employment taxes retroactively plus potential penalties. That said, it might be worth one polite attempt before filing the SS-8, especially if you can frame it as helping them avoid larger penalties down the road. Just be prepared that they'll likely refuse and you'll need to proceed with the formal process.
