This is in line with the tax rates for 2016. Assuming that you are single, your gross income of $41,000 would result in a taxable income of $30,650 if you took an exemption for yourself ($4050) and the standard deduction ($6300).
That means you'd be in the 15% tax bracket. Your tax would be computed as $927.50 plus 15% of the amount over $9,275.
Of course, you may have other details that aren't considered here.
