Most people like receiving a tax refund – it's kind of like a windfall for many people, especially those for whom saving is a difficult discipline. However, getting a big tax refund from the IRS may not necessarily be the best thing for you in certain situations.
Try to think about your refund in a different way. Essentially, you are giving the government an interest-free loan, which they give back to you when you file your taxes. There's really no reason to do that, other than you like the surprise surplus.
A lot of people don't like the idea of owing the government, or are afraid they will not have the money available at tax time to pay the bill. That is a valid concern.
However, if you adjust your withholding enough so that you owe on April 15, that also means you have more money in your paycheck each month.
In reality, whether you owe the government or they owe you, the amount of tax collected is virtually the same. The difference is whether you have your taxes paid for you via your paycheck, and have a smaller paycheck because of it (and a refund in the spring), or whether you set the money aside on your own and have a little bit more to take home from work every pay period.
If you set your withholding so that you'll owe at tax time, you are in essence holding your own money longer. This can be helpful in situations, such as being in debt, where payments are due every month. By having extra in your paycheck due to having less money deducted for taxes, you could use the extra money to pay a little more on your debt, thereby reducing the amount of interest you pay in the long run. Some people like that approach.
Whether you like to keep your own money until tax time or whether you prefer the windfall method, you can achieve your preference by going to visit your Human Resources administrator. If you want more money in your paycheck – and possibly owing the IRS, claim more dependents.
If you prefer a refund, claim fewer dependents. The form to make changes on is called a W-4. It's always good practice once a year to review your tax and financial situation and make adjustments as necessary.
