Use the Arizona Form 140X-SBI to correct a small business income tax (Arizona Form 140-SBI, 140NR-SBI, or 140PY-SBI).
If you are amending a return for any other tax year, use the amended return (Form 140X-SBI) that is available for that specific tax year.
Form 140X-SBI will be your new tax return. This return will change your original return to include the new information. The entries you make on Form 140X-SBI are the entries you would have made on your original small business income tax return had it been done correctly.
