Navigating Montana’s income tax for the 2016 tax year requires accurate completion of Montana tax forms and federal form details. Taxpayers must determine their filing status and calculate federal AGI to decide whether to use Form 2, 2EZ, or 2EC. Understanding Montana form requirements, Schedule II subtractions, and itemized deductions ensures proper wages, interest, and other compensation reporting.
Timely filing by April 18, 2017, avoids late-filing penalties and interest on unpaid taxes. The Department of Revenue applies progressive tax brackets and tax rates based on your Montana taxable income. Part-year residents must verify household income thresholds, submit payment or extension requests, and sign required schedules to prevent underpayment penalties.
Claiming credits such as the qualified endowment credit, dependent care expense deduction, and the ABLE Act account subtractions reduces the taxes you owe. Your exemption amounts and eligibility for refundable credits hinge on residency status and contributions. Reviewing all subtractions, credits, and deductions on Schedule II and Schedule V allows you to optimize refunds or minimize money paid to the Department of Revenue.
Overview of Montana State Income Tax for 2016
Who Needs to File
- Single or Married Filing Separately (under age 65): You must file if your federal gross income (excluding unemployment compensation) was $4,460 or more, because that threshold ensures you meet Montana’s minimum income tax requirement.
- Single or Married Filing Separately (age 65 or older): You must file if your federal gross income was $6,840 or more, accounting for the higher exemption available to senior taxpayers.
- Head of Household: You must file if your income was $8,920 (under 65) or $11,300 (65+) or above, reflecting Montana’s household filing thresholds considering your dependents and support obligations.
- Married Filing Jointly: If both spouses are under 65, file when income is $8,920 or more; if one spouse is 65 or older, file when income is $11,300 or more; if both are 65+, file when income is $13,680 or more.
- Blind Exemption: All taxpayers who are legally blind receive an additional $2,380 exemption when determining their filing requirement, lowering the income threshold needed to file and offering relief for visual impairment.
Residency Status
- Full-Year Resident: You lived in Montana the entire year or maintained a permanent home here and intended to return. This status requires reporting all income from anywhere.
- Part-Year Resident: You moved into or out of Montana during 2016 with the intent to establish a permanent residence elsewhere or here. Your Montana tax applies only to income earned while a resident.
- Nonresident: You did not live in Montana during 2016 but had Montana-source income; you report only that income on Form 2 with Schedule IV to allocate it correctly.
Montana Tax Brackets and Rates
Montana uses a progressive tax bracket system, increasing your tax rate with higher taxable income. For 2016, rates started at 1% on the first $2,900 taxable income, rising through 2%, 3%, 4%, 5%, and 6% brackets, and topping out at 6.9% for income over $17,400. When you complete Schedule II subtractions and calculate your Montana AGI, apply these brackets on the Montana tax table to determine your final tax liability.
Notable 2016 Changes
- ABLE Act Subtraction: Taxpayers could subtract up to $3,000 in qualifying ABLE account deposits from Montana income, enhancing tax-advantaged savings for individuals with disabilities.
- Unlocking Public Lands Credit Increase: The per-access credit rose from $500 to $750, with a maximum of $3,000, encouraging public access to private lands for recreation.
- New Educational Credits: Innovative Educational Program and Student Scholarship Organization credits (up to $150 each) were introduced to incentivize donations supporting education in Montana.
Montana Tax Forms to Use
Individual Returns
- Form 2 (Long Form): Use this when you have business income, capital gains, rental property, itemized deductions, or are a nonresident/part-year resident. It captures complex federal AGI adjustments.
- Form 2EZ (Short Form): Use this if you are a full-year resident with only wages, limited interest income, no capital gains or itemized deductions, and claim the standard deduction only.
- Form 2EC (Elderly Homeowner/Renter Credit): Montana residents age 62+ with household incomes under $45,000 use this to claim rent or property-tax credits on their returns.
Business Returns
- Form CLT-4S (S Corporation): All S corporations with any Montana-source income file this composite return, reporting corporate and shareholder information.
- Form PR-1 (Partnership/LLC): Partnerships and multi-member LLCs with Montana-source income use this composite return to report allocations and credits.
- Form PT-AGR (Pass-Through Owner Agreement): Owners of pass-through entities complete this to agree to Montana jurisdiction and filing requirements.
Common Schedules
Form 2’s schedules align your federal AGI with Montana’s rules and capture state-specific deductions or credits. Completing each schedule correctly ensures your Montana taxable income and taxes owed are accurate.
- Schedule I: Montana Additions to Federal Adjusted Gross Income. This schedule lists income items the IRS excludes but Montana taxes, such as certain retirement distributions or forgiven debt, ensuring state taxable income reflects Montana law.
- Schedule II: Montana Subtractions from Federal Adjusted Gross Income. Use this to claim Montana-specific subtractions—like ABLE Act deposits or Social Security benefits—that reduce your state taxable income and lower your tax liability.
- Schedule III: Montana Itemized Deductions. Here, you itemize deductions unique to Montana, including medical expenses, property taxes, charitable contributions to eligible organizations, and mortgage interest. Completing Schedule III lets you compare your total itemized deductions to the standard deduction and choose the method that minimizes your taxable income.
- Schedule IV: Nonresident/Part-Year Resident Tax. This allocates Montana-source income for nonresidents and part-year residents, so you pay tax only on in-state earnings, ensuring fair taxation based on residency status.
- Schedule V: Montana Tax Credits. List nonrefundable and refundable credits—such as the qualified endowment credit or dependent care expense deduction—to reduce your Montana tax owed or increase your refund.
- Schedule VI: Credit for Income Tax Paid to Another State or Country. Claim this credit if you paid tax on the same income elsewhere, preventing double taxation and ensuring you only pay the higher of the two state rates.
- Schedule VIII: Reporting of Special Transactions. Use this schedule to report complex items—such as installment sales or federally taxed partnerships—that require detailed treatment under Montana tax law.
Step-by-Step Instructions to Complete Your Return
STEP 1: Gather and Organize Documents
Collect all 2016 Montana tax forms, federal form W-2s, and 1099s to verify wages, compensation, and other income. Assemble records for itemized deductions—such as property taxes, charitable contributions, and the dependent care expense deduction—and gather documentation of ABLE account contributions to optimize subtractions and credits.
STEP 2: Enter Personal and Federal Information
On Montana Form 2, accurately enter your name, SSN, filing status, and residency status, then transfer federal AGI figures from your IRS Form 1040. Reporting your household income, interest, and other information precisely ensures your state taxable income base aligns with federal calculations.
STEP 3: Calculate Montana AGI and Taxable Income
Use Schedule I and Schedule II to add back disallowed federal items and subtract Montana-specific subtractions—like qualified endowment credit contributions or ABLE Act deposits—from your federal AGI. Decide between the 20% standard deduction or itemized deductions on Schedule III, then calculate your final taxable income to apply the correct progressive tax brackets and rates.
STEP 4: Compute Tax and Apply Credits
Refer to Montana’s tax table for the 2016 tax year to calculate income taxes owed. Complete Schedule V to claim nonrefundable and refundable tax credits—such as the qualified endowment credit and dependent care expense deduction—and ensure part-year residents correctly allocate Montana-source income on Schedule IV.
STEP 5: Enter Payments, Penalties, and Interest
On Form 2, record all income taxes paid through withholding, estimated, and extension payments. Calculate late-filing and late-payment penalties and compute interest at Montana’s 8% rate on unpaid balances. Accurate entries here determine your final payment or refund.
STEP 6: Finalize, Sign, and File
Review each page and schedule for completeness, and sign and date your return. You can choose to e-file through the TransAction Portal or print and mail your paper return using black ink to the Department of Revenue. Ensure all forms and payments are postmarked by April 18, 2017, to avoid penalties.
How to File Your Return
Electronic Filing
Electronic filing streamlines the submission of Montana tax forms and federal form data for the 2016 tax year. The TransAction Portal (TAP) on the Department of Revenue website lets taxpayers file state returns, calculate income tax owed, and schedule payments in one session. E-filing applies built-in error checks to reduce mistakes and speeds up refunds or confirmations compared to mailed returns.
Paper Filing
If you prefer to file on paper, complete all Montana forms in black ink, sign each page, and assemble schedules in order. Attach W-2s, 1099s, and supporting documents (such as proof of dependent care expense deductions or ABLE Act contributions). Mail your return by April 18, 2017, to the appropriate address:
- With payment:
Montana Department of Revenue
PO Box 6308
Helena, MT 59604-6308
- Without payment or expecting a refund:
Montana Department of Revenue
PO Box 6577
Helena, MT 59604-6577
Ensure you include any payment voucher and use the correct mailing address to avoid late-filing penalties and interest on unpaid tax.
Extensions
Montana automatically grants a six-month extension on filing without requiring an additional form if your 2016 tax liability was $200 or less, or you paid 90% of your estimated 2016 tax or 100% of your 2015 tax by April 18. The extension applies only to completing and submitting your return. Any balance due still accrues interest at 8% per year and late-payment penalties until paid in full.
How to Make a Payment
Electronic Methods
- Electronic Funds Withdrawal: When you e-file on the TransAction Portal, you can schedule a direct debit from your bank account. This option lets you select any date up to April 18, 2017, simplifying payment calculation and avoiding penalties.
- E-Check: Montana’s TAP and Income Tax Express support e-check payments with no processing fee. Enter your routing and account numbers, submit the form, and the Department of Revenue will deduct the money directly from your account.
Card & Mail-In Payments
- Credit/Debit Card: You can remit payment online via TAP or third-party providers using a credit or debit card. A convenience fee applies, so factor that into your total payment to ensure you meet the full income taxes paid deadline.
- Check or Money Order: Mail a U.S. funds check or money order payable to “Montana Department of Revenue.” Include your SSN, “Tax Year 2016,” and payment voucher on the memo line, then mail to the correct address to file by the deadline.
Deadlines & Penalties
- Payment Deadlines: Your 2016 income tax payment was due April 18, 2017, coinciding with the estimated payment for the first quarter of 2017. Subsequent estimated payments were due June 15, September 15, and January 16, 2018.
- Underpayment Penalties & Interest: If you paid less than 90% of your tax liability or estimated payments, Montana imposes a 1.2% per month late-payment penalty (up to 12%) plus 8% annual interest on unpaid balances.
How to Track Your Refund or Balance Due
Refund Status
- Online “Where’s My Refund?” Tool: Enter your SSN and refund amount on the “Where’s My Refund?” tool to see e-filed returns processed in about two weeks and paper returns in roughly 18 weeks.

- Confirm Filing Status & Residency: To apply the proper exemptions and brackets, determine your correct filing status and part-year or full-year residency.
- Attach Schedules & Supporting Docs: Include Schedule I–VI or VIII as needed, plus W-2s, 1099s, and proof of deductions like property taxes and dependent care expense deduction.
Small Business Filers
- Entity-Specific Forms: Sole proprietors use Form 2; partnerships/LLCs file PR-1; S corporations submit CLT-4S by March 15; C corporations use CIT by May 15.
- Composite Returns & K-1s: S corporations must complete Schedule I–IV, K-1s, and Form PT-AGR for nonresident shareholders to claim tax credits and allocations properly.
- Maintain Records: Keep copies of all Montana tax forms, federal forms, payment vouchers, and schedules for at least three years to satisfy IRS and state audit requirements.
Electronic-Filing Checklist

- Save Confirmation: Print or save the acceptance page and confirmation number, then archive digital and paper copies of your return and attachments.
Post-Filing Tips
- Amendments & Notices: If the IRS adjusts your federal return, file an amended Montana return within 180 days to report changes and avoid additional penalties.
- Future Planning: Begin preparing for next year’s tax year in June or July by estimating contributions, withholding adjustments, and eligible credits to minimize underpayment interest.
Special Considerations for Small Businesses
Filing Requirements by Entity
Small business owners must select the correct Montana form based on their entity type to comply with state income tax rules. Sole proprietors report business income and deductions on Schedule C via Form 2, while partnerships and multi-member LLCs file Form PR-1 to allocate revenue and expenses. C corporations use Form CIT by May 15, and S corporations submit Form CLT-4S by March 15, ensuring each taxpayer’s filing status and household income thresholds are appropriately addressed.
S Corporation Details
S corporations with Montana-source income complete Schedule I for apportionment, Schedule II for tax credits, and Schedule III to report shareholder compensation and property allocations. Nonresident shareholders must sign Form PT-AGR to consent to Montana jurisdiction before the credits flow through on K-1s. This ensures eligible owners can claim the qualified endowment credit and other business tax credits without triggering penalties.
Multistate Apportionment
Businesses across state lines calculate their Montana taxable income using the three-factor formula—property, payroll, and sales—on Schedule I of Form PR-1 or CLT-4S. This method allocates a percentage of overall revenue to Montana, ensuring equitable application of tax rates and preventing double taxation by the IRS or other states when you file your annual return.
Common Pitfalls
Many small business taxpayers overlook critical deadlines, omit Schedule IV for part-year residents, or fail to sign required pages, resulting in late-filing penalties and interest charges. Inaccurate entries of federal AGI, missing Schedule VIII for special transactions, or improper deduction claims can trigger Department of Revenue notices, so review each Montana tax form carefully before submission.

Frequently Asked Questions
What if I missed the filing deadline?
Suppose you missed the April 18, 2017, deadline. File immediately to minimize penalties. There is no penalty if you’re due a refund, but you must file within three years to claim it. If you owe tax, you face a late-filing penalty (the lesser of $50 or the tax due) and a late-payment penalty (1.2% per month up to 12%).
Can I e-file for free?
Montana Free File and the TransAction Portal (TAP) provide free e-filing for eligible taxpayers based on AGI thresholds. Volunteer Income Tax Assistance (VITA) and Tax Counseling for the Elderly (TCE) also offer free preparation services for qualifying low-income, elderly, and disabled taxpayers. Before filing electronically, verify eligibility requirements on the Montana Department of Revenue website.
What deductions are most commonly missed?
Montana taxpayers often overlook the federal income tax subtraction (up to $5,000 for singles, $10,000 for joint filers); contributions to Medical Care Savings Accounts, First-Time Home Buyer or Family Education Savings Accounts (each up to $3,000); and the partial pension and annuity income exemption. Reviewing Schedule II subtractions and Schedule III itemized deductions helps ensure you claim all eligible subtractions.
How do I request an extension?
Montana automatically grants a six-month extension to October 16 if you meet one of several conditions: your 2016 tax liability was $200 or less; you paid 100% of your 2015 liability or at least 90% of your 2016 liability by April 18; you are a first-time filer; or you had zero or negative prior-year income. No form is required.
Can I file jointly if I moved mid-year?
If one spouse is a resident and the other a nonresident, you cannot file a joint Montana return; each must use Married Filing Separately, reporting only your income, deductions, and credits. The nonresident spouse completes Schedule IV to allocate Montana-source income. You may file a joint part-year return if spouses move in or out together.
Who has to file a Montana S corporation return?
Any S corporation with Montana‐source income must file Form CLT-4S by March 15. Montana-source income arises if the corporation has shareholders living in Montana, owns real or tangible property in Montana, or employs workers in the state. Each condition creates a tax nexus under Montana law, requiring the corporation to report and pay Montana income taxes.
