“What he telling you isn't true. As a self employed contractor you pay both halves of fica tax. You can't write off your clothing or your gas to get to work. As an employee you pat only half of the fica tax. You are also covered under workers compensation, have wage protections…”
“Hi, TaxAct here! With 1099 self-employment, business net profit generally flows to Schedule C, then income tax and self-employment tax on your joint return. Your approach (reconstructing income and expenses from what you still have, not inventing deductions) is a good call. When…”
“It’s your job to know if you owe, not your CPA’s. And if you made money that wasn’t taxed, 💯 you should know. 1099 income that was not taxed. Yep you owe. Apply your income tax rate from the prior year or cap gains tax rate as applicable, now you know what you owe before…”
1099 workers frequently misunderstand that their income isn’t taxed upfront, leading to unexpected tax liabilities when filing. Many fail to set aside money or make estimated payments, resulting in penalties and large bills.

“A 1099 doesn't come with withholding, and you'd owe about 15.3% self-employment tax on top of income tax. His trucks, his equipment and his schedule sound like a W-2 job. If he won't fix it, Form SS-8 gets the IRS to rule on your status, and Form 8919 lets you pay only your share of FICA. Keep your own record of hours and pay. [re: Boss wants to take taxes out]”

As an employee you pat only half of the fica tax. You are also covered under workers compensation, have wage protections, and do not need you own liability insurance.

Apply your income tax rate from the prior year or cap gains tax rate as applicable, now you know what you owe before deductions, credits, etc. It’s very little effort.

“Self employment tax is not double FICA, it's the same (approximately). The difference is that a self employed person pays both the employer and employee portions. An employee only sees their half even though the employer pays the rest.”
“You have a lot of misconceptions about this. Commutes are not deductible, including for 1099. 1099 workers also pay self employment tax, which is double what you pay for FICA.”
“I recently started a small 1099 gig and expect to make ~$4,300 for the year, which as I understand equates to ~$4,000 in net self-employment income. Can I use use that $4,000 to BOTH: Contribute $4,000 to a Traditional IRA, and *also* Claim (up to) $4,000 of Self-Employment Health Insurance deduction? And in essence, reduce total adjusted gross income by ~$8,000? I tried to do some research, as well as ask Claude, and was seeing some contradictory answers, so wanted to pose it to the tax profess”
“W-2 withholding does not automatically cover 1099 self-employment tax, so the side work needs its own set-aside even if you claim 0 on the W-4. People either add extra W-4 withholding or send 1040-ES payments; which is better for your refund situation is a tax-pro call. Log the 1099 income separately from the W-2 paycheck. Estimated payments go through IRS.gov (Direct Pay). Not tax advice.”
“I work all of 2025 as a contractor for a company. Receive 1099s, file taxes as if self-employed, contribute to solo 401k as if self-employed. Now an SS-8 is filed with the IRS, and the IRS rules that during my tenure with the company I was actually an employee during all of 2025. What happens to my solo 401K contributions? Do they all have to be rolled back? submitted by /u/buthazlettsdead [link] [comments]”
“To expound on the good answer already provided, the type of income matters. If this was a W-2 job, the previous answer applies. If this is treated as a contract or 1099 or self-employment gig, the tax threshold is much lower, at just $400 for the year. If you file a return for any reason, you must report all income regardless of amount or source or whether a form was received. If they took taxes out (specifically Social Security and Medicare), you were very likely an employee. If they did not, y”
“Im a 20 yr old college student working for my dads business’s and get paid through mercury/venmo. I hold a secondary bank account purely for taxes but i really dont want all that to go straight to the government if it doesn’t have to. Is there any legal loopholes or ways i can use it for say business expenses through an LLC or deduction? I could use a new laptop for school/remote work and i heard it could technically be a business expenses submitted by /u/Wonderful-Cloud-9850 [link]”
“He might if he’s been paying self-employment taxes. A lot of people who work 1099 write off as many things as possible so they pay very little tax which means their Social Security check is calculated on that small income. My dad worked hard his whole life, but most of it he was self-employed, and he tried to show as little income on paper as possible so he could avoid paying child support in a reasonable amount. When he got old and needed Social Security his check was like $700. That man was st”

“Yes. Very often labor companies try to take advantage of their employees with this. They either aren’t aware or are very aware that they’re doing this. In the end you would owe additional self employment taxes. The only benefit to you is if your husband incurs a good deal of unreimbursed expenses from this job. If so, he would file a sch C for the 1099 income and deduct certain business expenses to counter the income. You should consult a professional to evaluate whether this is a possibility fo”
“He is setting his own schedule but the truck, trailer, all lawn equipment, chemicals, etc are owned by the company he is working for. Thank you for this great information!!”
“I love tax questions where the most important fact is missing —— HOW MUCH is the income from the 1099?”
“The biggest difference is that a 1099 worker is considered self-employed, not an employee. That means no federal income tax, Social Security, or Medicare taxes are automatically withheld from his pay. Because of that, there is a good chance you’ll owe taxes when you file your joint return unless you’ve been making estimated tax payments or have enough taxes withheld from another job. He will generally owe self-employment tax, which covers both the employee and employer portions of Social Securit”
“The taxes for this income will not be automatically withheld. You two can increase the withholding at your w2 jobs so you don't owe taxes at tax time. Or you can make estimated tax payments. Yes, you call calculate roughly how much taxes this income will add to your total tax liability, so that you can do that increase of withholding or estimated tax payments.”
