Possible itemized deductions are:
- Medical and dental costs above and beyond 7.5% of your AGI
- State, local, real estate, and personal property taxes (capped at $10,000)
- Home mortgage interest
- Charitable donations and gifts

- Single - $12,000
- Married Filing Separately - $12,000
- Married Filing Jointly - $24,000
