Rules and decisions to review
- A deduction is not a dollar-for-dollar refund. Its value depends on the applicable tax calculation.
- Taxpayers generally compare the standard deduction with allowable itemized deductions, while other deductions may follow separate rules.
- Nonrefundable credits can reduce eligible tax to zero, but generally do not create a refund by themselves. Refundable credits may produce a payment beyond tax owed.
- The same expense cannot be used repeatedly for incompatible tax benefits. Education and dependent-care expenses need especially careful allocation.
A practical example
A $1,000 deduction and a $1,000 credit are not equivalent. The deduction reduces income subject to tax; an eligible credit reduces the relevant tax directly, subject to its refundable or nonrefundable rules.
Records to gather
Gather income documents, expense receipts, dependent information and any forms establishing eligibility for credits.
Your next step
List potential deductions and credits separately, then match each with its eligibility evidence. Compare the standard and itemized deductions and check for incompatible uses of the same expense.
