Per-Taxpayer vs Per-Return
Tax Glossary Term
Definition
Per-taxpayer vs per-return describes whether a tax benefit is measured individually for each person or once for the entire tax return, regardless of filing status. This distinction matters most on joint returns where both spouses may independently qualify for a benefit. The OBBBA senior bonus deduction is per-taxpayer: if both spouses on a joint return are age 65 or older, each claims the full $6,000, for a combined deduction of $12,000. The child tax credit ($2,200 per qualifying child in 2026) is another per-taxpayer variant (technically per-qualifying-child) where the benefit multiplies with the number of eligible dependents. By contrast, the SALT deduction cap is per-return for most filers: a married couple filing jointly shares a single $40,400 cap, not $40,400 each. The standard deduction is also effectively per-return because each filing status has its own fixed amount (single: $16,100, MFJ: $32,200) rather than simply doubling the single figure. Understanding this distinction prevents costly errors when estimating joint-return benefits. Married Filing Separately sometimes converts a per-return limit into a per-taxpayer limit (each spouse gets their own SALT cap on their own return), which is one reason some couples consider MFS despite its other drawbacks.
Example
Married Filing Jointly, both spouses age 67, in 2026:
Senior bonus deduction (per-taxpayer):
Spouse A: $6,000
Spouse B: $6,000
Combined: $12,000
SALT deduction (per-return):
Combined state/local taxes paid: $65,000
Deduction allowed: $40,400 (not $80,800)
