Alabama Form 40 Schedule CR – Credit for Taxes Paid to Other States (2026)
Last reviewed: 2025-11-12
Use the Alabama Tax Form Calculator Alabama Form 40 Schedule CR – Credit for Taxes Paid to Other States as a stand alone tax form calculator to quickly calculate specific amounts for your 2026 Alabama state tax return. Alternatively, you can use one of our Combined Federal and State Tax Estimators to quickly calculate your salary, tax, and take-home pay.
Alabama Schedule CR allows residents who earned income and paid income tax in another state to claim a credit on their Alabama income tax return. This ensures that taxpayers are not taxed twice on the same income. The form is filed with Form 40 and requires detailed reporting of each state where tax was paid, the income amount, and the corresponding credit limit based on Alabama’s rate structure.
This calculator is designed to simplify the process: you can compute the credit for one state at a time and then add additional states to a summary table, which automatically totals the credits claimed across jurisdictions. This reflects the multi-state credit calculation used on Schedule CR, Columns A–F.
How to Use the Alabama Schedule CR Calculator
- Step 1 – Enter State Information: Select the other state in which you paid income tax. Input the taxable income, tax paid, and any adjustments required under Alabama law.
- Step 2 – Compute Credit per State: The calculator uses the Alabama rate of 5% to compute the “tax due to that state using Alabama rates” (Column D). The credit allowed (Column F) is the lesser of the tax paid to the other state (Column E) or the computed Alabama equivalent (Column D).
- Step 3 – Add Multiple States: Use the Add State button to append each calculation to a running list. The table automatically totals your overall credit across all states at the bottom.
- Step 4 – Transfer Total: Enter the total credit from the final “Totals” row onto Form 40, Line 24.
Always retain proof of tax payments made to other states, such as W-2s, 1099s, or tax return copies. Alabama may request documentation to verify the claimed credit.

Understanding the Credit for Taxes Paid to Other States
The credit for taxes paid to another state is a vital protection for Alabama residents who work or conduct business across state lines. Without this credit, the same income could be taxed twice — once by the state where it was earned and again by Alabama, the state of residence. Schedule CR ensures fair treatment by limiting Alabama’s claim to tax only the portion exceeding what was already paid elsewhere.
Alabama’s Department of Revenue bases this credit on reciprocity principles, ensuring residents do not face double taxation, especially in neighboring states like Georgia, Mississippi, or Florida (for those with certain business income). This encourages regional employment mobility and supports families who live in Alabama but commute or operate in adjacent jurisdictions.
Examples
Example 1 – Wages in Another State: Michael, an Alabama resident, worked in Georgia and paid $1,500 in Georgia tax on $30,000 of income. Alabama’s tax on that income is $1,200, so his allowable credit is $1,200 — the lesser of the two amounts.
Example 2 – Business Income Split Across States: Sarah operates a business with $20,000 earned in Mississippi and $60,000 in Alabama. She pays $800 in Mississippi tax. Alabama’s computed equivalent tax on that portion is $1,000, so her credit is limited to $800.
Example 3 – Multiple States: John works part-time in Georgia and Tennessee. Each state’s income and tax paid are computed separately using the calculator, then totaled on the “Totals” row for Line 24 of Form 40.

Frequently Asked Questions
What records should taxpayers keep to document capital gains and losses reported on Schedule D?
Taxpayers should retain brokerage statements, consolidated 1099 forms, purchase confirmations, sale confirmations, cost-basis records, improvement receipts for real property, and depreciation schedules for any assets subject to annual deductions. Alabama audits often focus on basis accuracy and verification of loss carryovers, so keeping documentation for both acquisition and sale is essential. For long-term holdings, records may go back many years and should be stored securely. Even when brokerage firms track basis, taxpayers bear ultimate responsibility for accuracy. Maintaining detailed records ensures clean reporting and reduces the risk of adjustments or disallowed losses during review.
Does sales or property tax affect this page?
This page models income/payroll taxes only; other taxes affect your budget, not paycheck math.
Where can I get help understanding complex allocation scenarios on AL-40NR?
Complex allocation issues—such as multi-state employment, remote work with periodic Alabama presence, cross-border business operations, or shared pass-through ownership—often require careful review to avoid over-reporting or under-reporting Alabama income. You can begin by exploring the detailed nonresident calculator at https://www.taxformcalculator.com/calculator/alabama/al-40nr.html, which helps you model income scenarios and validate your allocation percentages. This tool can be especially helpful for part-year movers who had pay originating in one state while performing duties in another. It also assists in identifying which adjustments and credits need to be prorated. For filers with pass-through entities, rental property, or substantial business activity, methodical use of the calculator can prevent errors that may otherwise lead to amended returns, delayed refunds, or Alabama Department of Revenue inquiries.
Why don’t my brackets match payroll tables?
Employers may use different rounding/timing tables; small variances are normal.
What documentation should taxpayers keep to support KRCC-I claims?
Taxpayers must retain the original Alabama Capital Credit certificate, pass-through K-1 statements showing their credit allocation, project approval letters from the Alabama Department of Commerce, prior-year KRCC-I schedules reflecting carryforward balances and the certified project number. Supporting documentation must demonstrate the taxpayer’s ownership interest for each period in which the credit is claimed. While Alabama does not require filing all documents with the return, the Department of Revenue can request them at any time, and incomplete documentation may result in a denied or reduced credit. These records should be retained for the full credit duration, as claims may span up to 20 years.
