A deduction of tax from your federal tax return does not mean that you can deduct your federal income tax from you your gross income. A deduction of tax means that you can deduct taxes other than federal income tax from your gross income.
In general, any tax that is NOT federal income tax (excise, transfer, luxury tax, etc) is deductible from your gross income. State, local, and foreign income taxes are all deductible. One major tax that is not deductible from an individual¿s gross income is sales tax of any kind. Businesses may deduct sales tax from their gross income though. State income taxes are deductible in the year following taxation since a taxpayer cannot know his correct taxation amount until the year after he pays his taxes.
An interest deduction is a deduction allowed by the IRS taken because the taxpayer was forced to pay interest on a particular debt incurred. The general rule is that interest is deductible. The major exception to this is that consumer interest is not deductible. In a sense, the exception almost swallows the main rule, because things like credit card interest payments and other similar interest payments are not deductible from gross income.
The IRS has decided this particular type of consumer interest is deductible after all. Interest charged on loans secured by a qualified residence are in the end deductible. The taxpayer may deduct interest on loan repayment on up to two homes. The maximum a taxpayer may borrow towards those homes is $1,000,000 for an acquisition indebtedness home (standard mortgage home), or $100,000 for an equity indebtedness home (standard home equity loan).
In an effort to give recent former students a break during the early years of their education loan repayment process, the IRS has decided to allow those paying interest on education loans to deduct up to a maximum of $2500 per year from their gross income.
With the plethora of tax software out there, most people are capable of doing their taxes on their own. More sophisticated and more complex tax returns (i.e. those done by business owners) may require more time and perhaps the advice of a lawyer. Additionally, should you have a dispute with the taxing authority you may need to go to court, and then a busisness lawyer may be required.
