question regarding W4
Yes. W4 determines how much your employer will withhold from your wages. Leaving everything at default would mean that your salary is your only taxable income, and you only take default deductions. Your employee will calculate your tax withholding based on that. But, if your salary is >200k, I assume that you have other income (investment/capital gains, interest on your bank account), which you will have to pay taxes on. You're probably going to have some deductible expenses (business/partnership expenses, mortgage interest, donations, college funds etc) as well. So it is very likely, unless you're really not smart about money, that you have more to do with your taxes than just the employers' withholding. There are still ways that the default values on the W4 can lead you to get a refund or owe the IRS. If there was a big delta in your paychecks, it can lead to problems. If you make 260,000 and get 26 paychecks that means each check had a gross of 10,000. Your company will withhold the same amount from each check. But If you earned a big bonus then the smaller regular paychecks may not have been withholding enough.  When bonus checks are involved the payroll office has to treat them as irregular pay to be able to make it work out. Some companies don't do this, so you may under or over pay during the year. If you changed companies during the year, this can lead to under or over payment. The lower paying company would not know about the higher rate of pay at the other company. so at one you would under pay, and the other you would over pay. There are also social security issues with more than one employer.
"There are many questions and good answers here regarding investment choices. The first decision you need to make is how involved do you intend to be in investment activity. If you plan to be actively investing by yourself, you should look for questions here about making investment choices. If you intend to be a more passive investor, look for posts by ""Bogleheads"", who focus on broad-focused, low cost investments. This is the optimal choice for many people. If you are not comfortable managing investments at all, you need to figure out how to find a competent and reasonably priced financial advisor to meet with and guide your investment strategy. This advice generally costs about 1-2% of your total managed assets annually." First, I'd use an online tax calculator to figure out you total tax tab for the year. Then look through Circular E and figure out from there how much tax you should pay for the rest of the year and work backwards to calculate the number of allowances to get there.  Two friendly warnings - Since you are doing this midyear, you'll need to repeat this exercise as we go into 2017. These next 6 months, you'll be withholding less than normal to make up for the high holdings so far. Second, a withholding is like saying tax/don't tax me on $4050. So in the 25% bracket, it's +/- $1000 in tax paid. You can adjust closer via the line 6 on W4 'additional withholding'. "With that credit rating you should have no trouble getting a rate in that range. I have a similar credit score and my credit union gave me a car loan at 1.59%. No haggling required. In regards to your question, I think you have it backwards. They are more likely to give you a good rate on a high balance than a low one. Think about it from the bank's perspective... ""If I give you a small sale, will you give me a discount?"" This is the question you are asking. Their profit is a factor of how much you borrow and the interest rate. Low rate=less profit, low financing amount = less profit.  The deal you proposed is a lose-lose for them." Credited to your account means amount has been deposited to your account(this will be your income). Debited from your account means withdrawn from your account(This will be your expense). Hope this clarifies your question. Regards Jayanthi Can I work on 1099 from my own company instead of on W2? The reason is   on W2 I can't deduct my commute, Health Insurance and some other   expenses while on 1099 I think I can able do that. Since I am going to   client place to work not at my own office, I am not sure whether I   should able to do that or not. If you have LLC, unless you elected to tax it as a corporation, you need neither 1099 nor W2. For tax purposes the LLC is disregarded. So it is, from tax perspective, a sole proprietorship (or partnership, if multiple members). Being a W2 employee of your own LLC is a bad idea. For all these above expenses, which can I use company's debit/credit   card or I need to use only my personal debit/credit card? It would be better to always use a business account for business purposes. Doesn't matter much for tax per se, but will make your life easier in case of an audit or a legal dispute (limited liability protection may depend on it). If I work on 1099, I guess I need to file some reasonable taxes on   quarterly basis instead of filing at year end. If so, how do I pay my   tax on quarterly basis to IRS? I mean which forms should I file and   how to pay tax? Unless you're a W2 employee, you need to do quarterly estimate payments using form 1040-ES. If you are a W2 employee (even for a different job, and even if it is not you, but your spouse with whom you're filing jointly) - you can adjust your/spouse's withholding using form W4 to cover the additional tax liability. This is, IMHO, a better way than paying estimates. There are numerous questions on this, search the site or ask another one for details. If you are in the US and a regular employee, this will have to show up on your year-end W2 form as income. If it doesn't, there is some funky accounting business going and you should probably consult a professional for advice. On the back of the W4 is a Deductions and Adjustments worksheet. This worksheet will give you an accurate number to enter on line 5 of your W4. If you don't receive a W2, there are 2 scenarios you should consider: If you have reason to believe that scenario 1 is accurate, then you could file your taxes based on the last valid paycheck you received. If you have reason to believe that scenario 2 is accurate, then you need to do some extra math, but fortunately it is straight forward. Simply treat your final paychecks as if the gross amount of your check was equal to the sum of your taxes paid, and the net amount of the check is $0. This way your income will increase by the proper amount, and you will still receive credit for the taxes paid. This should work out cleanly for federal and state taxes, but will likely result in an overpayment of FICA taxes. You can use form 843 to receive a refund of excess FICA taxes. As a side note, I'd recommend spot checking the YTD numbers on your last paychecks against previous paystubs to make sure there wasn't any fuzzy math going on when they realized they were going out of business.
