Common confusion points
Which prior years to use
Some taxpayers think the two most recent years, but it must be the two years immediately preceding the current tax year
→ Verify the tax year on each prior return
Averaging percentages
Percentages differ for farm vs. fishing income
→ Use the correct table in the Schedule J instructions
Where to put the credit
The line number changes each year
→ Check the current Form 1040 instructions for the exact line
Electronic attachment
Some software may not auto‑attach Schedule J
→ Manually upload the PDF before final submission
Rounding rules
IRS requires rounding to the nearest dollar
→ Apply standard rounding, not truncation
