I make $6,600 a month and my company stopped taking taxes out. How much should I expect to owe come tax season?

Were they taking taxes out before?

Has your work changed significantly?

Being an employee (and subject to withholding) is a matter of facts and circumstances. Your payer cannot simply reclassify you as a contractor because he's too lazy to do it properly.

If you believe he's doing it correctly, you need to sit down and do a dummy tax return (just use the 2009 forms) and see what the bill comes out to be. You will owe around $930 a month for SE tax alone. (Use form 1040 C-EZ and SE. Tax rates from 2010 1040ES.)

If you believe he's NOT doing it correctly, look at form SS-8. You file that, the IRS contacts him and makes a determination. If the IRS agrees, you file 1040 with form 8919 and only pay $505 a month for fica/mc.

Income taxes are the same no matter what--can't guess at that total, but it looks like at least 15% if not 25%,

Edit: If you have been a contractor for 2 years, be advised that not only do you have to save out the money for taxes, you have to SEND IT IN quarterly. If you need to micromanage the amount and minimize the amount you send in, you should look at form 2210. Otherwise if you owe, you will be subject to the 8% estimated tax penalty.

That is very difficult to determine without a great number of details regarding your specific circumstances. The common wild guess offered is 30% but that is nothing more than a guess. if you were my client I would want to know the purpose for the change and are you pleased with this change. If you are your income will treated as an independent contractor and you will file a Schedule C with your return. On that form you report your income and expenses related to the activity. The net is used to calculate your tax liability. Since you will have had some wage income and withholding the two type of income must be combined to figure you income tax liability and the net is used to figure your self-employment tax. I always suggest seeking the advise of a tax professional in these circumstances.

This does put you in a tough spot because you've probably already spent that refund so its harder to pay it back now then it would have been it simply not get it at all. But the bottom line is you owe the tax. You owed the tax before you ever went to the tax guy so you'll have to pay it. The interest and penalties are his fault. Some tax preparation people have accuracy guarantees where they will pay the interest and penalties in a situation like this (but you still pay the original tax). Generally you must prove on paper that you gave them all the correct info and they messed it up. This is hard to do, so its very hard to collect on that guarantee (if your tax company even has one). If the tax company won't pay the interest and penalties, you can ask the IRS to waive the penalties and they usually will, but they cannot legally waive the tax or interest portions, so you have no choice but to pay that.

whenever you get paid you need to demand a pay stub of your earnings and how much tax is being withheld

for them to arbitrarily change your status they cannot if you are performing the same work, and the advise to get an SS8 from IRS is very wise

however, back to your immediate problem, your se tas is approx 15.3% of your Sch C 'net' and that is calculated on SCh SE

half of that is a credit to reduce your gross income

but you need to file and pay your estimated taxes on 1040ES with the only two remaining coupons, Sept. 15 and Jan 15 of next year

se taxes can possibly be mitigated with the EIC if you are eligible, otherwise it is a mandatory payment

what your income tax will be will depend on your status, dependents, deductions etc.

If your job function has not changed then if you were an employee before, you are an employee now. An employer can't change horses in the middle of the stream even if you agree. File an IRS Form SS-8 to get your status clarified.
