Can I Pay Taxes in a Lump Sum Instead of Paycheck Withholding?
I currently have a regular 9-5 where federal and state taxes are taken out of every paycheck automatically. Been thinking lately - is it actually allowed and legal to just pay all my taxes in one big payment at the end of the year instead of having chunks taken out of every check? Or maybe just have minimal withholding throughout the year and pay most of it later? It just seems like I'm missing out on potential investment returns or at least some interest on this money that's being withheld every two weeks, especially since taxes aren't technically due until April. I could be putting that money to work for me all year! This is probably a super basic question but I've never really thought about it before. Anyone here have experience with adjusting their withholding to maximize keeping money in their own accounts longer? Thanks in advance for any advice!

You've actually hit on a good point many people overlook! Yes, it's completely legal to reduce your withholding and pay more at tax time, but there are some important things to consider. You can adjust your withholding by submitting a new W-4 form to your employer. You could claim more allowances or even request a specific dollar amount reduction. However, be careful - the IRS has what's called an "underpayment penalty" if you don't pay enough throughout the year. To avoid penalties, you generally need to pay (through withholding or estimated payments) either 90% of your current year tax or 100% of last year's tax (110% if your income is over $150,000). These payments should be made somewhat evenly throughout the year. Many people do exactly what you're suggesting - they calculate the minimum they need to withhold to avoid penalties, then invest the difference and pay the remainder at tax time. Just be sure to actually set that money aside so you're not scrambling in April!

•Thanks for the info! So if I understand right, I need to make sure I'm still paying enough each quarter to avoid penalties? Is there a specific form I need to fill out if I reduce my withholding but want to make quarterly payments for the difference? And how do I calculate exactly how much I need to withhold to hit that 90% mark?

•Yes, you're on the right track! If you reduce your withholding below the safe harbor amounts, you'd need to make quarterly estimated tax payments using Form 1040-ES. These are due April 15, June 15, September 15, and January 15 of the following year. Calculating the 90% threshold can be tricky since you'd need to predict your total tax for the current year. That's why many people use the 100% of last year's tax method (or 110% for higher incomes) since that number is known. Just take your total tax from last year's return, divide by 4, and that's your quarterly payment amount. Remember that withholding is considered paid evenly throughout the year even if it's not, which gives it an advantage over quarterly payments.

This strategy totally changed my financial situation last year. After reading about this, I adjusted my W-4 to withhold just enough to avoid penalties and started investing the difference. I was nervous at first, but I found this amazing tool at https://taxr.ai that helped me calculate exactly how much I needed to withhold to stay penalty-free. The site analyzed my past returns and projected my current year's taxes, then gave me the exact numbers to put on my W-4. It even reminded me when quarterly payments were due. By the end of the year, I had earned almost $2,700 in investment returns from money that would've otherwise just been sitting with the IRS interest-free!

•Wait, how does the tool know what your current year tax will be? My income changes quite a bit year to year so I'm not sure if last year's tax would be a good guide. Does it account for things like stock sales or rental income?

•I'm pretty skeptical about these tax calculator sites. How accurate was it really? Did you end up owing exactly what it predicted or were you still surprised at tax time? I'm worried about getting hit with a huge unexpected bill.

•The tool asks for your expected income sources for the current year and any major changes from prior years. It then runs projections based on that information, applying current tax laws to give you a solid estimate. It's been surprisingly accurate for me even with some variable income. As for the accuracy question - it was within about $300 of my actual tax bill, which I considered pretty impressive. The key is being honest and thorough when inputting your information. What I liked most was that it let me adjust the "confidence level" - I set mine to be slightly conservative, so I ended up getting a small refund rather than owing. You can also update your projections mid-year if your situation changes.

Just wanted to follow up on my experience with https://taxr.ai after being skeptical initially. I decided to give it a try a few months ago, and I'm actually really impressed. I uploaded my past returns, answered some questions about my current income situation, and it gave me a customized withholding strategy. The interface walks you through everything step by step, and explains the calculations in plain English. I adjusted my W-4 according to their recommendation in May, and have been investing the difference in a high-yield account. Already made about $800 that would have just been sitting with the IRS! The quarterly payment reminders have been super helpful too - got a text notification last week about the upcoming payment. For anyone wondering if this actually works - yes, it absolutely does. Just make sure you're disciplined about setting aside the money you'll need for your quarterly payments or year-end bill.

I tried for MONTHS to get through to the IRS to ask about adjusting my withholding properly and the penalties. Literally could not get a human on the phone despite calling at all different times. Finally found https://claimyr.com and watched their demo at https://youtu.be/_kiP6q8DX5c which showed how they could get me connected to an actual IRS agent without the wait. Used their service and had a 45-minute conversation with an IRS representative who walked me through exactly how to calculate my required withholding and explained all the safe harbor rules in detail. The agent even sent me follow-up materials about estimated tax payments. Such a relief to get definitive answers directly from the IRS instead of trying to piece together information from various websites. Now I have a withholding strategy I'm confident about because it came straight from the source.

•How does this even work? The IRS phone system is notorious for being impossible. Are they somehow jumping the queue or do they have special access? Seems too good to be true.

•Yeah right. No way this actually works. I've been trying to reach the IRS for THREE YEARS about an issue with my 2022 return. If this actually worked, everyone would be using it and the IRS would shut it down.

•They use a proprietary system that continuously redials and navigates the IRS phone tree until they secure a spot in the queue. Once they have a spot, they call you and connect you directly to the agent. It's all totally legitimate - they're just automating the painful process of getting through. No special access or relationships with the IRS - they're just solving the technical problem of getting through the phone system. Think of it like having a really persistent assistant who keeps trying the phone line for you instead of you having to do it yourself for hours.

Ok I have to eat my words. After being completely skeptical about Claimyr, I decided to give it a shot because I was desperate to resolve my ongoing tax issue. I honestly expected it to be a waste of money, but figured it was worth trying anything at this point. Got a call back in about 57 minutes saying they had an IRS agent on the line. I nearly fell out of my chair. Had a 30-minute conversation with an extremely helpful agent who not only answered all my withholding questions but also helped resolve the issue with my 2022 return that had been hanging over my head for years. I'm still in shock that it actually worked. If you're struggling to get through to the IRS and need definitive answers on withholding rules or anything else, this service is legitimate. I've already recommended it to my brother who's been trying to sort out an identity theft issue with the IRS.

Another approach nobody's mentioned yet - if you're self-employed or have significant side income, you can adjust your W-4 at your main job to account for that additional income. I'm an engineer with a consulting side gig, and I just increased my withholding at my day job slightly instead of making separate quarterly payments for the consulting work. My accountant says this is totally legit as long as your total withholding covers your tax liability appropriately. For me it's way easier to have a bit more taken from each paycheck than to remember four separate quarterly payment deadlines!

•Does this really work for all types of income? I have rental property income on top of my regular job. Can I just adjust my W-4 to account for that instead of making estimated payments?

•Yes, this approach works for rental income too! The IRS doesn't care where the withholding comes from as long as the total amount is sufficient. Just calculate the additional tax you expect to owe from your rental income and divide it by the number of paychecks remaining in the year. On your W-4, there's a section for "extra withholding" where you can put that additional amount per paycheck. The advantage is that withholding is considered to be paid evenly throughout the year even if you increase it later in the year, which can help avoid underpayment penalties in some cases. Just be sure your total withholding will meet one of the safe harbor requirements (either 90% of current year tax or 100%/110% of last year's tax).

•This is absolutely terrible advice that will get people in trouble. The IRS definitely DOES assess underpayment penalties if you don't make payments throughout the year. You're either making this up, have a very unusual tax situation, or have just been extremely lucky that you haven't been audited yet.

•I have to agree with Ravi here - claiming exempt when you don't qualify is actually illegal and can result in serious penalties. To legally claim exempt, you must have had no tax liability last year AND expect to have no tax liability this year. The underpayment penalty is real and kicks in when you owe $1,000 or more at tax time without meeting the safe harbor requirements. You might have gotten away with it so far due to refunds from other credits, changes in tax laws, or just luck, but it's definitely not a strategy I'd recommend to others. The approaches mentioned earlier about calculating proper withholding amounts or using tools to stay penalty-free while investing the difference are much safer ways to achieve the same goal of keeping more money in your pocket throughout the year.

Great question! I went through this exact same thought process a couple years ago. You're absolutely right that you can legally adjust your withholding - I reduced mine significantly and have been investing the difference in index funds. The key is understanding the safe harbor rules everyone mentioned. I use the "100% of last year's tax" method since it's the most predictable. Just take your total tax from line 24 of last year's 1040, divide by your number of paychecks, and make sure at least that much is being withheld each pay period. One thing I learned the hard way - set up a separate savings account for your tax money and automate transfers into it every payday. It's way too tempting to spend that extra cash if it just sits in your checking account. I treat it like another bill that has to be paid. The psychological benefit is huge too. Instead of feeling like the government is taking my money all year, I feel like I'm choosing when and how much to pay. Plus last year I earned about $1,200 in returns on money that would've just been an interest-free loan to the IRS!

•This is exactly the kind of practical advice I was looking for! The separate savings account idea is brilliant - I can definitely see how tempting it would be to just spend that extra money if it's sitting in my regular account. Quick question though - when you calculate that "100% of last year's tax" amount, are you looking at the total tax before any withholding/credits, or the amount you actually owed after everything was applied? I want to make sure I'm using the right number for my calculations. Also, what type of index funds have you been using for the short-term investment? I'm wondering if there's a sweet spot between growth potential and liquidity since I'll need access to the money by April.
