everybody is a lawyer, doctor, CA.... all the speciality in one person. you ask anything and you get tons of replies.
here are my 2 cents.
1. If you don't itemize, forget about most deductions. In general, you don't pay mortgage, nothing is tax deductible because you would rather take standard deduction.
2. If you itemize, state tax, part of what you pay to DMV, mortgage interest, county taxes etc. are deductible. Any refund from state from last years return is taxable this year.
(someone mentioned here that state tax deduction is fundamental...why would you pay tax twice... blah blah ha ha ...
what about social security tax, medicare tax... you din't find them fundamental ?... you can not deduct these...)
3. medical expenses over 2% or of income are generally deductable (if spent on qualified dependents).
4. Tax preparation, Immigration exp. etc. fall under misc. deductions. Meaning part of these all expenses over 7% (please check the number. never bothered about this because it is highly unlikely that you would ever exceed that percentage ) of of income is deductible. Therefore, for most, these deductions will be useless. If you run small business, probably you could deduct them all as business expenses (if you could show that it was a reasonable expense to run your business).
5. I use turbo tax, read lots of stuff throught the year. If you are not confortable or confused about something, I would suggest you to visit a tax consultant. Two advantages: 1. he might save you some money or/and 2. he might save you from falling into audit trap. For most people here, turbo tax should be more than enough. If you have only w-2 income, don't pay mortgage and don't trade stocks, I will call you stupid if you go to a tax consultant for return preparation. I can do your taxes in less than 5 minute and so can you (unless of course you did not buy your grad/undergrad degree from street
).
enjoy tax time.
