I haven't had any life changes like marriage or kids, but I didn't realize the tax laws had changed. Is there somewhere specific I should look at my return to see if that's affecting me? And yeah, my W-4 looks totally different than the last time I filled one out years ago. I'm confused about how to fill it out properly for next year to avoid this happening again.

The W-4 redesign definitely makes things confusing. The new form tries to be more accurate but requires more information. For your situation, pay special attention to Step 2 if you have multiple jobs (like your main job plus a side gig) - that's where a lot of people mess up. You probably need to look at your marginal tax bracket - when you got that promotion, you might have pushed some of your income into a higher tax bracket. The old W-4 wouldn't automatically adjust for that. The IRS has a Tax Withholding Estimator on their website that's actually pretty helpful for figuring out the right withholding amount.

Yes, there actually is! The IRS has something called "First Time Penalty Abatement" which they don't advertise much. If you've had a clean tax record for the past 3 years, you can often get penalties removed for a first-time issue. You just need to call them and specifically ask for this. You can also request abatement by writing a letter explaining if you had a reasonable cause for the underpayment - like if you had a major life change, calculation error, etc. They can be surprisingly understanding if you approach it the right way.

That's really interesting, I hadn't heard of this option before. Would this affect my credit score or have any long-term impacts? I'm worried about creating problems for myself down the road.

An Offer in Compromise itself won't directly impact your credit score the way debt settlement with private companies might. However, tax liens used to appear on credit reports (though the credit bureaus removed them from reports in 2018 as part of their National Consumer Assistance Plan). The bigger consideration is that the process is lengthy and there's a filing fee unless you qualify for a low-income exemption. During the review period, collection activities are generally paused, but interest and penalties continue to accrue. If your offer is rejected, you'll owe the original amount plus all accumulated interest and penalties. For most people with a $10k tax bill and regular income, a payment plan is usually more practical. The Offer in Compromise is more suitable for those with very limited income and assets who genuinely cannot pay their tax debt over time.

The HSA tip is gold! I managed to contribute $4,150 to my HSA for the previous year (did it in April before filing) and saved about $900 in taxes. Not enough to fix a $10k problem but every bit helps. For next year, def adjust your W-4 at your new job. When I started my new job I put "0" allowances and had them withhold an extra $100 per paycheck. Made a huge difference.

I hadn't even thought about reporting bank accounts! What's the threshold again - is it $10k across all accounts combined or each account needs to be over $10k?

It's $10k across all foreign accounts combined at any point during the year. So if all your UK accounts added up to over $10k even for one day, you need to file. This includes accounts you have signature authority over, even if not yours (like a joint account with a partner or business account). The form is fairly straightforward but needs to be filed electronically through the FinCEN BSA filing system. You'll need to report maximum account values, account numbers, bank addresses, etc. Keep in mind this is separate from your tax return and goes to the Treasury Department, not the IRS.

That fee used to be like $450 not that long ago! The US gov dramatically increased it when too many people started renouncing. Plus if your net worth is over $2M or your average tax liability over 5 years exceeds a certain threshold, you could be hit with an exit tax. Not a simple solution unfortunately.

Wait, really? I've been investing for 5 years and never knew this. So if my dividends automatically buy more shares, I need to add those amounts to my original investment when calculating gains/losses?

Exactly! When dividends are automatically reinvested to buy more shares, you've already paid income tax on those dividends in the year you received them. Those reinvested amounts become part of your cost basis. If you don't add them to your cost basis, you'll end up paying tax twice - once when you received the dividend, and again when you sell the shares (because your gain would appear larger than it actually was). This is especially significant for long-term holdings where years of reinvested dividends can substantially increase your true cost basis.

I've been using TaxAct for the last three years and it's pretty good with investments. You can import most 1099-B forms directly or enter them manually. Much cheaper than TurboTax but still gets the job done.

Thank you! I've already updated both my W4 forms for this year, but I'll definitely use that calculator to double-check everything. Is it normal to owe this much though? I'm still shocked at how big the difference was.

Yes, unfortunately the amount you owe is pretty typical for this situation. When you add a second job with similar income, you're essentially doubling your income but your withholding isn't doubling the tax paid because each employer is calculating withholding based on their portion only. For example, if you make $80K at one job, you might be withheld at an effective rate of about 12-15%. But when your total income is $160K, portions of that income are taxed at 22% or 24% brackets. That difference between what was withheld (at lower rates) and what you actually owe (at higher rates) is where that $5K+ bill comes from.

This is good advice. Also, make sure you're taking the standard deduction at a minimum ($12,950 for single filers for 2022). And if you made any charitable contributions or had work-related expenses that weren't reimbursed, those might help too.

Thanks for bringing this up! I do have some student loan interest from when payments were still required, and I contributed to my 401k at both jobs. I'll definitely look into those deductions. Do you think it could significantly reduce what I owe?
