What is Schedule OR-ASC?
Schedule OR-ASC, or the Oregon Adjustments for Form OR-40 Filers, is a crucial component of the Oregon state income tax return process. This form allows taxpayers to report specific additions to income and deductions that impact their Oregon taxable income. It’s designed for individuals filing the standard Form OR-40.
The instructions emphasize meticulous attention to detail, specifically requiring all entries to be completed using UPPERCASE letters and either blue or black ink. Maintaining legibility is paramount for efficient processing. Furthermore, the form must be printed at its actual size (100%) to ensure compatibility with scanning and processing systems. Submitting photocopies or using staples is explicitly prohibited by the Oregon Department of Revenue.
Who Needs to File Schedule OR-ASC?
Schedule OR-ASC is required for all Oregon residents and part-year residents who file Form OR-40, the standard Oregon individual income tax return. This includes taxpayers who have specific adjustments to their federal income that need to be reported for Oregon tax purposes.
Specifically, individuals claiming additions to income, such as unemployment compensation or certain retirement distributions, must utilize this schedule. Similarly, those eligible for Oregon-specific deductions, like educational expenses or contributions to certain funds, will also need to complete and submit Schedule OR-ASC alongside their Form OR-40. Remember to use UPPERCASE letters and blue or black ink!
Different Versions of the Schedule OR-ASC
Oregon offers variations of Schedule OR-ASC tailored to different filing statuses. OR-ASC is for those filing Form OR-40, while OR-ASC-NP is specifically designed for individuals filing either Form OR-40N (for nonresidents) or Form OR-40P (for part-year residents).
It’s crucial to use the correct version corresponding to your filing status to ensure accurate tax reporting. Both versions require the use of UPPERCASE letters and either blue or black ink. Always verify you are utilizing the most current revision of the form, as indicated by the revision date (e.g., Rev. 08-14-23) to avoid potential issues with processing.

Key Instructions for Filing
Always utilize uppercase letters and blue or black ink when completing Schedule OR-ASC. Ensure printing is at 100% scale; avoid staples and photocopies.
Using Uppercase Letters and Ink Color
Strict adherence to formatting guidelines is essential when preparing Oregon Schedule OR-ASC. The Oregon Department of Revenue explicitly mandates the use of uppercase letters throughout the entire form. This requirement ensures clarity and facilitates efficient processing by the department. Furthermore, only blue or black ink is permitted; other colors may cause rejection of your filing.
These stipulations apply to both the Schedule OR-ASC and its related form, OR-ASC-NP. Utilizing the correct ink color and letter casing isn’t merely a suggestion, but a firm instruction. Failure to comply with these simple, yet critical, guidelines can lead to delays in processing or even rejection of your return. Double-check your completed form before submission to guarantee adherence to these rules.
Printing and Submission Guidelines
Accurate presentation of your Oregon Schedule OR-ASC is vital for smooth processing. The Department of Revenue requires printing the form at its actual size – 100% scale – to ensure readability and compatibility with their systems. Avoid any scaling or resizing during the printing process. Submissions of photocopies are strictly prohibited; original forms are necessary for acceptance;
Furthermore, do not use staples, paper clips, or any other binding methods when submitting your schedule. A clean, flat submission is preferred. These guidelines apply to both Schedule OR-ASC and OR-ASC-NP. Following these instructions diligently will help prevent delays and ensure your return is processed efficiently and accurately by the Oregon Department of Revenue.
Form Specifics: OR-ASC vs. OR-ASC-NP
Oregon offers two distinct adjustment schedules: OR-ASC for those filing Form OR-40, and OR-ASC-NP for filers using Form 40N or 40P. The OR-ASC is designed for standard Oregon income tax returns, while the OR-ASC-NP caters to non-resident and part-year resident filers; Both forms require the use of uppercase letters and blue or black ink for completion.
Despite the shared formatting requirements, the adjustments reported on each form may differ based on your residency status. The OR-ASC-NP specifically addresses adjustments relevant to income earned outside of Oregon or during periods of non-residency. Always ensure you are utilizing the correct schedule corresponding to your filing status to avoid processing errors.

Line-by-Line Breakdown of Adjustments
Schedule OR-ASC requires reporting additions to income and claiming deductions, utilizing specific adjustment categories as outlined by the Oregon Department of Revenue instructions.
Reporting Additions to Income
Schedule OR-ASC necessitates reporting specific additions to your federal adjusted gross income when filing your Oregon tax return. These additions can include items such as income from out-of-state sources not previously taxed, certain expenses deducted in prior years that are now disallowed, and adjustments related to Oregon investment credits.
Carefully review the instructions to determine which additions apply to your individual tax situation. Accurate reporting of these additions is crucial for calculating your correct Oregon taxable income. Remember to utilize uppercase letters and black or blue ink when completing the form, ensuring legibility for processing. Failure to report additions correctly may result in penalties or adjustments to your tax liability.
Claiming Deductions
Schedule OR-ASC allows Oregon taxpayers to claim specific deductions that reduce their federal adjusted gross income to arrive at their Oregon taxable income. These deductions can include items like interest paid on student loans, contributions to Oregon’s 529 college savings plans, and certain business expenses for self-employed individuals.
It’s vital to carefully review the eligibility requirements for each deduction to ensure you qualify. Accurate documentation supporting your claimed deductions is essential in case of an audit. Remember to complete the form using uppercase letters and black or blue ink, maintaining clarity for efficient processing. Properly claiming deductions minimizes your tax liability and maximizes potential refunds.
Specific Adjustment Categories
Schedule OR-ASC encompasses several distinct adjustment categories impacting your Oregon tax return. These include adjustments for income reported on federal Schedule K-1, relating to Oregon source income, and adjustments for certain state and local tax expenses. Additionally, adjustments exist for items like moving expenses, potentially deductible if work-related and meeting specific criteria.
The form also addresses adjustments related to the Oregon Opportunity Grant and contributions to qualified retirement plans. Thoroughly understanding each category and its associated requirements is crucial for accurate filing. Remember to utilize uppercase letters and black or blue ink when completing the form, ensuring legibility and efficient processing by the Oregon Department of Revenue.

Common Adjustments and Credits
Oregon’s OR-ASC often involves the University Venture Development Fund credit, requiring pro-ration for new residents. Various other Oregon tax credits may also apply.
University Venture Development Fund Credit
The University Venture Development Fund Credit, reported on Schedule OR-ASC, is a significant adjustment for some Oregon taxpayers. This credit is specifically for contributions made to qualified university venture development funds within the state. However, it’s crucial to understand that if you moved to Oregon after making the contribution, the credit isn’t taken at its full value immediately.
Instead, the credit must be pro-rated based on your “Oregon percentage,” which reflects the portion of the year you were an Oregon resident. This ensures fairness and aligns the credit with your residency status. The pro-ration calculation is detailed in the OR-ASC instructions, and proper application is essential for accurate tax reporting. Failing to pro-rate correctly could lead to discrepancies and potential issues with your return.
Other Common Oregon Tax Credits

Beyond the University Venture Development Fund Credit, Schedule OR-ASC accommodates various other Oregon tax credits impacting your state tax liability. These include credits for childcare expenses, working family benefits, and potentially, credits related to energy efficiency improvements made to your home.
Taxpayers should carefully review the OR-ASC instructions to determine eligibility for these credits, as specific requirements and limitations apply. Documentation is key; retain receipts and supporting information to substantiate any credits claimed. Remember to accurately calculate and report these adjustments to ensure compliance with Oregon tax laws and maximize potential tax savings. Thoroughness and attention to detail are vital when completing this schedule.

Oregon Percentage Calculation
Determining your Oregon percentage is vital when prorating credits for those new to the state, ensuring accurate tax calculations on Schedule OR-ASC.
Determining Your Oregon Percentage
Calculating your Oregon percentage is essential for accurately prorating tax credits if you moved to Oregon during the tax year. This percentage reflects the portion of the year you were an Oregon resident. To determine this, divide the number of months you were an Oregon resident by the total number of months in the tax year (twelve).
For example, if you moved to Oregon on July 1st and filed for the entire year, you would be an Oregon resident for six months. Your Oregon percentage would then be 6/12, or 50%. This percentage is then applied to various credits and adjustments reported on Schedule OR-ASC to reflect your partial-year residency.

Applying the Oregon Percentage to Credits
Once your Oregon percentage is calculated, it’s crucial to apply it correctly to any applicable tax credits claimed on your return. This ensures you only receive credit for the portion of the year you were an Oregon resident. The Oregon percentage directly impacts credits like the University Venture Development Fund credit, requiring a proportional reduction if you weren’t a full-year resident.
Multiply the total credit amount by your Oregon percentage to determine the amount you can claim. For instance, a $6,000 credit with a 50% Oregon percentage would result in a $3,000 claimable credit. Accurate application of this percentage is vital for compliant tax filing.
