Essential Guide: How to File Your Maine Tax Return for 2022

Filing your Maine tax return for 2022 requires a clear understanding of federal and state requirements. This guide explains how to file your 2022 Maine tax return using Form 1040ME for individuals and Form 1120ME for corporations subject to corporate income tax. You will learn how to transfer federal adjusted gross income (AGI) to Maine’s forms, apply Maine‐specific modifications, and decide whether to use itemized or standard deductions. Detailed instructions cover each form page, ensuring you report all income, calculate your taxable income correctly, and remain compliant with income taxes and taxation rules.

Maine’s income tax rates range from 5.8 percent to 7.15 percent, so identifying your marginal rate is essential for accurate withholding and estimated payments. This guide shows you how to apply tax credits—such as the enhanced Earned Income Tax Credit, Student Loan Repayment Credit, and other refundable credits—to lower your effective property tax rate and overall tax liability. You will also find information on local sales taxes, estate tax considerations, and excise taxes, including the per‐gallon cigarette tax, to help individuals and business owners understand every factor affecting their Maine taxes.

Your 2022 return is due on April 18, 2023; if you cannot meet this deadline, you may file an extension using Form ME and pay any estimated tax to avoid penalties. Instructions for paper filing include the correct mailing addresses, voucher forms, and how to respond to any IRS or state notices you receive after filing. Examples and figures illustrate common scenarios—such as how renters can claim the Property Tax Fairness Credit—and demonstrate the steps to calculate amounts due or refunds you may receive. By following this guide, every taxpayer will be equipped to file accurately, claim all eligible credits, and pay what they owe on time.

Overview of Maine State Income Tax for 2022

Who Needs to File

• Full-year residents: Must file if they meet federal filing requirements, sorting all income—wages, interest, dividends, and business earnings—before applying Maine’s additions and subtractions. Filing ensures you remain compliant with federal and state obligations and helps you claim all eligible credits.
  
  
• Part-year residents & nonresidents: File only if you have Maine-source income that creates tax liability, reporting earnings such as wages or rental income earned within the state. This targeted reporting prevents you from paying tax on income earned elsewhere while ensuring Maine taxes you fairly on in-state earnings.
  
  
• Refund seekers: Even without a mandatory filing requirement, submit a return to claim withheld taxes or refundable credits like the Earned Income Tax Credit. Lower-income taxpayers or those whose sole source of income was subject to withholding may find it advantageous to file taxes in these circumstances, as they may receive an unexpected refund.
  
  

Standard Deductions & Filing Thresholds

• Standard deduction: Offers relief by reducing your taxable income—$12,950 for single filers, $19,400 for heads of household, and $25,900 for married filing jointly. Choosing the standard deduction simplifies your return if itemized expenses are lower.
  
  
• Personal exemption: If you qualify, this is a flat $4,450 deduction per taxpayer, lowering your taxable income state rates. This exemption applies whether you itemize or take the standard deduction, offering consistent relief across filing types.
  
  
• Filing thresholds: Combine the standard deduction and exemption to set minimum income levels—single filers file if taxable income exceeds $17,400; heads of household above $23,850; joint filers above $30,350. These thresholds protect low-income individuals from unnecessary taxes while maintaining fairness in the tax system.
  
  

Income Modifications

• Additions (Schedule 1A): Include income items excluded from federal AGI but taxable in Maine, such as interest on out-of-state bonds or specific business income adjustments. Correctly reporting additions ensures Maine captures all taxable earnings and avoids underpayment penalties.
  
  
• Subtractions (Schedule 1S): Cover deductions that reduce your Maine taxable income, including up to $25,000 in pension income and pandemic-related relief payments. Claiming these subtractions can significantly lower your state tax burden, especially for retirees and those who received COVID-19 stimulus funds.
  
  
• Why it matters: Accurately applying additions and subtractions is critical for determining your correct Maine adjusted gross income, identifying the appropriate marginal rate, and preventing either overpayment or underpayment penalties. This precision ensures you pay only what you owe—and no more.
  
  

Key Changes for Tax Year 2022

Maine introduced several essential updates for the 2022 tax year that may impact your liability and available credits. Reviewing these changes ensures you take full advantage of new deductions and credits when completing Form 1040ME.

• Pension Income Deduction Increase: The deduction for non-military retirement benefits rose from $10,000 to $25,000, allowing more retirees to reduce their taxable income significantly. This change will lower your marginal rate and increase your potential refund if you qualify. Military retirement benefits continue to be fully exempt.
  
  
• Enhanced Earned Income Tax Credit: The state portion of the Earned Income Tax Credit increased from 20 percent to 25 percent of the federal EITC for filers with qualifying children and from 20 percent to 50 percent for those without. This enhancement helps low- to moderate-income taxpayers keep more of their earnings. Claiming this credit reduces your effective property tax rate (through increased cash flow) and overall tax liability.
  
  
• New Student Loan Repayment Credit: Replacing the Educational Opportunity Tax Credit, the Student Loan Repayment Credit offers up to $2,500 per year—or $3,500 in certain circumstances—subject to a $25,000 lifetime cap. This refundable credit applies to qualifying student loan payments made in 2022 and can provide direct relief to borrowers. Documentation of your payments is required when completing Schedule A.
  
  
• COVID-19 Relief Payment Subtraction: Any COVID-19 relief payments included in your federal adjusted gross income can now be deducted on Schedule 1S. This subtraction reduces your Maine taxable income and prevents pandemic-related funds from increasing your state tax burden. Keep all relevant IRS notices or statements to support your subtraction claim.
  
  
• Property Tax Fairness Credit Improvements: The Property Tax Fairness Credit threshold was lowered. You now receive credit for property taxes exceeding 4 percent of your income (down from 5 percent), with a maximum credit of $1,000 or $1,500 for those 65 and older. This adjustment makes the credit accessible to more homeowners and renters. Use Schedule PTFC/STFC to find and claim your improved credit.
  
  

Required Forms and Schedules 

Below are the core forms and schedules you need for your 2022 Maine tax return.

Main Form 1040ME

• Form 1040ME: The primary return for residents, part-year residents, and nonresidents to report federal AGI and Maine modifications. Completing it correctly determines your state taxable income and refunds or balances due.

Common Schedules

• Schedule PTFC/STFC (Property & Sales Tax Fairness Credits): Use this schedule to claim a credit for the property taxes you paid or the sales tax you owe based on your income. Homeowners can offset part of their property tax bill, while renters may claim an equivalent credit. Completing Schedule PTFC/STFC accurately can lower your Maine tax liability by reimbursing some expenses.
  
  
• Schedule 1A (Income Addition Modifications): Report income items that increase your Maine adjusted gross income but were excluded from federal AGI, such as interest on out-of-state bonds or certain passthrough business income. Adding these amounts back ensures Maine taxes all relevant income and prevents underpaying state taxes. Schedule 1A also covers adjustments for depreciation recapture and federal deduction limitations.
  
  
• Schedule 1S (Income Subtraction Modifications): Subtract qualifying amounts from your federal AGI to determine Maine taxable income. Common subtractions include up to $25,000 of pension or retirement income and pandemic-related relief payments. Other eligible subtractions may include contributions to Maine’s college savings program or certain military pay. Proper use of Schedule 1S can significantly reduce your taxable base and potential tax due.
  
  
• Schedule A (Tax Credits): Claim nonrefundable and refundable credits that reduce your Maine tax liability or increase your refund. Key credits include the enhanced Earned Income Tax Credit, Child Care Credit, and the new Student Loan Repayment Credit. Schedule A also captures credits for education expenses, historic property preservation, and alternative energy investments. Accurately completing this schedule maximizes the benefits available to eligible taxpayers.
  
  
• Schedule 2 (Itemized Deductions): Itemize eligible expenses such as unreimbursed medical costs, mortgage interest, charitable contributions, and state and local taxes instead of taking the standard deduction. Use Schedule 2 only when your total itemized deductions exceed the standard deduction amount. Detailed backup documentation is required to support itemized claims and can help reduce your taxable income.
  
  
• Schedule NR (Nonresident Credit): Calculate the credit available to part-year and nonresidents to avoid double taxation on income earned inside and outside Maine. This schedule allocates your Maine tax liability based on the proportion of your total income sourced to Maine. Proper completion ensures that you pay tax only on in-state earnings and receive a credit for taxes paid to other jurisdictions.
  
  

Step-by-Step Guide to Filing Your 2022 Maine Tax Return

Step 1: Gather Your Documents

Before you begin, assemble all necessary paperwork to start the filing process. Have your federal Form 1040 handy to copy your adjusted gross income, along with every W-2 and 1099 for wages, interest, dividends, and retirement distributions. If you plan to claim the Property Tax Fairness Credit, locate your property tax bills and any refunds. Furthermore, gather proof of student loan payments and any IRS notices showing COVID-19 relief payments. Finally, keep last year’s Maine return on hand to verify prior exemptions and elections.

Step 2: Complete Form 1040ME

Work through Form 1040ME in sequence, starting with personal details and the transfer of federal AGI from line 11 of your Form 1040 to line 14 of Form 1040ME. Next, adjust your income on Schedules 1A and 1S by adding out-of-state income and subtracting pension income (up to $25,000) or COVID-19 relief payments. Decide whether to claim the Maine standard deduction or itemize on Schedule 2 if your eligible expenses exceed the standard amount, then enter your $4,450 personal exemption and any dependent exemptions. Complete Schedule A to claim credits such as the enhanced Earned Income Tax Credit and the Student Loan Repayment Credit.

Step 3: Calculate Tax Liability and Credits

Determine your starting tax by locating your taxable income on Maine’s official tax tables or applying the rate schedules. Then, reduce that base amount by applying any credits you qualify for on Schedule A—like the EITC and Student Loan Repayment Credit—and Schedule PTFC/STFC for the Property Tax Fairness Credit. Finally, compare the sum of these credits and any Maine withholding or estimated payments against your calculated tax. If tax payments exceed your liability, you will receive a refund; if not, pay the difference by April 18, 2023, and your refund will earn interest.

Filing and Payment Options

Electronic Filing

Maine offers free E-filing through the Maine Tax Portal on revenue.maine.gov and many commercial tax software packages that support Form 1040ME. Filing electronically speeds up processing—typically 2–3 weeks for refunds—and provides immediate confirmation that your return was received. Direct deposit options are built in, so you can deposit any refund into your bank account without waiting for a paper check. Error-checking features also help reduce mistakes that could delay your return.

Paper Filing

If you prefer to mail a paper return, use Form 1040ME, promptly addressing red schedules and payment vouchers. Returns with payment are sent to Maine Revenue Services at P.O. Box 1067, Augusta, ME 04332-1067, while returns without payment—or those expecting a refund—go to P.O. Box 1066, Augusta, ME 04332-1066. Sign and date your return and mail it early to account for postal delays. Paper returns generally take 6–8 weeks to process refunds, so plan accordingly.

Payment Methods & Vouchers

You can pay any tax due electronically via the Maine Tax Portal using ACH bank transfer, electronic check, or credit/debit card (with processing fees). If you are filing on paper and owe tax, include Form 1040MT-ME when requesting an extension to pay without your signature confirmation of the estimated amount. You can also mail a check or money order payable to “Treasurer, State of Maine,” including your Social Security number and tax year on the memo line. Using the correct voucher ensures your payment is applied promptly and accurately.

Tracking Refunds and Balances

• Checking Your Refund: Visit the “Where’s My Refund?” tool and enter your Social Security number and the refund amount from your return. This tool provides real-time updates and an estimated date for your refund to be deposited or mailed.
  
  
• Review Processing Times: Understand that E-filed returns typically process in 2–3 weeks for refunds, while paper returns require 6–8 weeks for completion. Returns flagged for review due to missing information or errors may take longer, so monitoring the status can alert you to potential issues early.
  
  
• View Your Balance & Payment History: Create an account on the Maine Tax Portal to view your current balance, payment history, and any outstanding notices from Maine Revenue Services. Regularly reviewing your online account helps you stay informed of obligations and avoid unexpected penalties by addressing past-due amounts.

‍

Final Filing Checklist

• Completed Form 1040ME and Schedules: Ensure you have filed accurately, including 1040ME and all applicable schedules (PTFC/STFC, 1A, 1S, A, 2, NR). Missing a schedule can lead to processing delays or lost credits.
  
  
• Attached are the W-2s, 1099s, and Documentation: Include copies of all W-2s and those of 1099 forms and receipts for property taxes, student loan payments, and COVID-19 relief subtractions. Proper documentation supports your claims and helps avoid audits.
  
  
• Signed Return or E-file Confirmation: If filing on paper, sign and date your return; if e-filing, save the electronic acknowledgment. Maine Revenue Services cannot process your return without your signature or confirmation.
  
  
• Correct Mailing Address or Portal Submission: Mail paper returns with payment to P.O. Box 1067, Augusta, ME 04332-1067, and returns without payment to P.O. Box 1066, Augusta, ME 04332-1066. If you e-file, verify that your bank information is correct for direct deposit.
  
  
• Copies for Your Records: Make copies of your return, schedules, and all attachments before submission. Keeping a complete set of records helps if you need to. You can amend or reference your tax return in the future.
  
  
• Payment Arrangements: If you owe tax, include Form 1040ME-PV or 1040EXT-ME with your payment or electronically via the Maine Tax Portal. Paying on time by April 18, 2023, helps you avoid penalties and interest charges.

Frequently Asked Questions

What if I missed the April 18, 2023, deadline?

File your return as soon as possible to minimize penalties. Maine charges a penalty of 10 percent of unpaid taxes or $25, whichever is greater, plus interest from April 18, 2023. If you cannot pay in full, file on time and pay what you can. Then, contact Maine Revenue Services for proper payment.

Can I e-file my Maine return for free? 

Maine’s online Tax Portal provides all eligible taxpayers free E-filing for Form 1040ME. Electronic filing typically processes refunds in two to three weeks, including error checks to reduce mistakes. You can also choose direct deposit for faster refund delivery. Using the portal helps you confirm receipt immediately without mailing delays.

How do Maine income tax rates compare to those of other states?

Maine’s 2022 individual income tax rates range from 5.8 percent to 7.15 percent across progressive brackets. These rates are higher than many states with flat-rate systems but lower than states with top rates above eight percent. Comparing your marginal rate helps you estimate withholding and plan estimated payments accurately based on your projected taxable income.

What tax credits are available for Maine taxpayers?

Maine offers several tax credits on Schedule A to reduce your state liability or increase your refund. For 2022, major credits include the enhanced Earned Income Tax Credit—25 percent of the federal credit for those with children and 50 percent for those without—and the Student Loan Repayment Credit of up to $2,500.

Do I need to consider the estate tax when filing my Maine return?

Maine does not impose a separate state estate tax, so you generally will not report an estate tax liability on Form 1040ME. However, any income from an estate—such as inherited retirement distributions—remains taxable and must be reported. Executors may need to file the Maine fiduciary Form 1041ME to report estate income. Beneficiaries receive K-1s.

How do Maine corporate income taxes affect small business owners?

Corporations file state corporate income taxes using Form 1120ME at a flat 8.93 percent on taxable income. S corporations and LLCs, taxed as partnerships, pass income through to owners, who report it on Form 1040ME under individual rates. Choosing the proper entity structure can significantly affect state and federal tax liability.
