Who Needs to File Your Connecticut Tax Return for 2015?

Filing a Connecticut income tax return for the 2015 tax year is required under specific conditions. If you are a full-year, nonresident, or part-year resident, you may be required to file based on your income level and other factors. Understanding these criteria is essential to ensure compliance with Connecticut tax laws.

Residency Status

Full-Year Residents: If you lived in Connecticut for the entire year, you must generally file a return.
Nonresidents and Part-Year Residents: If you lived in Connecticut for only a part of the year or earned income there but did not reside there for the whole year, you must file using Form CT-1040NR/PY.

Income Requirements

You must file a return if your gross income exceeds certain thresholds. Here are the limits for 2015:

Married Filing Separately: $12,000
Single: $14,500
Head of Household: $19,000
Married Filing Jointly or Qualifying Widow(er) with Dependent Child: $24,000

Even if your income does not exceed these thresholds, you may still need to file if you had income tax withheld in Connecticut, made estimated tax payments during the year, or owe any taxes.

Special Conditions for Filing

If you are claiming the Connecticut Earned Income Tax Credit (CT EITC) or if you had a federal alternative minimum tax liability, you must also file a return.
Additionally, military retirement pay is fully exempt from Connecticut income tax for the 2015 tax year but still requires a filing to claim the exemption.

Meeting the filing deadline is essential, as missing it can result in penalties and interest charges.

Key Forms You’ll Need to File Your 2015 Connecticut Tax Return

To file your Connecticut tax return for the 2015 tax year, you must gather specific forms based on your filing status, income type, and whether you’re filing as an individual or as part of a business. Here’s a guide to the essential forms you’ll need and who should use them.

Forms for Individuals

Form CT-1040 is the primary form for Connecticut residents filing their income tax returns. If you lived in Connecticut for the entire tax year, you must complete and submit this form.
Form CT-1040NR/PY: If you were a nonresident or a part-year resident of Connecticut, use this form to file your return. It is designed for individuals who live in Connecticut for only part of the year or earn income from Connecticut sources.
Schedule CT-EITC: This must be attached to your return for individuals claiming the Connecticut Earned Income Tax Credit (CT EITC). The CT EITC is available to those who qualify based on income and family size.
Schedule CT-1040AW: Part-year residents must complete this form to allocate income earned while they were a resident of Connecticut. This is crucial for accurately reporting income from both Connecticut and out-of-state sources.
Form CT-1040 EXT: If you need more time to file, you can request an extension using this form. This extension allows you six additional months to file your return but doesn’t extend the deadline to pay any tax due.

Forms for Small Businesses and Pass-Through Entities

Small businesses and pass-through entities (such as partnerships, S corporations, and LLCs) have their own set of required forms:

Form CT-1065/CT-1120SI: This form is for partnerships, S corporations, and certain LLCs. It’s used to report income, deductions, and payments made on behalf of the business.
Form OP-424: If you’re filing for a business entity, you must also file this biennial tax return for S corporations, LLCs, and other similar entities.
Form CT-1065/CT-1120SI EXT: If you need an extension for your business’s pass-through entity tax return, use this form. Extensions must be filed electronically unless granted a waiver.

All these forms and additional schedules can be downloaded from the Connecticut Department of Revenue Services (DRS) website, which provides instructions for completing each.

Step-by-Step Guide to Filing Your Connecticut Income Tax Return

Filing your Connecticut tax return for the 2015 tax year involves several steps, from gathering the necessary documents to submitting your forms. Here’s a step-by-step breakdown of completing Form CT-1040 or Form CT-1040NR/PY for nonresidents and part-year residents. These steps will help you file correctly and claim all deductions and credits.

Step 1: Gather Your Documents

Before you begin filling out your Connecticut tax return, you’ll need to gather several key documents:

W-2 Forms: From all employers to report your wages.
1099 Forms: For any other income you received, such as interest, dividends, or self-employment income.
Federal Tax Return: You’ll need your IRS federal income tax return, which provides key information for your Connecticut return.
Other Income Documentation includes any social security payments, property taxes paid, or business income if you are a sole proprietor.
Social Security Numbers: For you, your spouse, and any dependents.

Step 2: Complete Personal Information

Name, Address, and Social Security Numbers: Enter your details at the top of Form CT-1040 or Form CT-1040NR/PY. If you are filing jointly, include your spouse’s information.
Filing Status: Check the appropriate box based on your filing status (Single, Married Filing Jointly, Head of Household, etc.).

Step 3: Calculate Your Connecticut Taxable Income

This is where you calculate your Connecticut Adjusted Gross Income (AGI):

Line 1: Enter your federal adjusted gross income from your IRS federal tax return.
Line 2: Add any additions to income, such as interest on non-Connecticut municipal bonds.
Line 3: Combine your federal income and additions to determine your total income.
Line 4: Subtract any subtractions from income, such as Social Security benefits or qualified retirement income.
Line 5: Your Connecticut AGI is the result of this subtraction.

Step 4: Apply Deductions and Credits

Deductions: You can subtract specific items, such as military retirement pay (100% exempt for 2015) and teacher pension income (10% exempt).
Tax Credits: If eligible, apply for the Connecticut Earned Income Tax Credit (CT EITC), property tax credit, and other available state credits.

Step 5: Calculate Your Tax

Line 6: Using the Connecticut income tax tables or calculation schedules, determine your tax based on your Connecticut AGI.
Lines 7-10: Apply any credits for taxes paid to other states, and calculate your alternative minimum tax (if applicable).
Line 11: If you're eligible for a property tax credit, enter the amount (up to $300).

Step 6: Determine What You Owe or Your Refund

Payments: Report the amount of Connecticut income tax that was withheld during the year. Include any estimated tax payments you made, and enter the total on Line 21.
Refund: If your total payments exceed the tax owed, you'll receive a refund. Complete the section to specify how you’d like to receive it (direct deposit or paper check).
Tax Due: Line 26 will show how much you owe if your tax liability exceeds your payments. If you pay by check, follow the instructions carefully to avoid delays.

Step 7: Finalize Your Return

Sign and Date: Make sure you sign and date your return. If filing jointly, both spouses must sign.
Include All Required Schedules: Double-check that you’ve included any necessary schedules, such as Schedule CT-EITC (for earned income tax credit) or Schedule 3 (for property tax credit).

Step 8: Submit Your Return

Once everything is filled out and signed, you can submit your return:

Electronic Filing: The fastest and most secure way to file your Connecticut tax return is through the Taxpayer Service Center (TSC) on the Connecticut Department of Revenue Services website.
Paper Filing: If you choose to file on paper, mail it to the correct address, which can be found on the Connecticut DRS website.

Following these steps will guarantee that you file your income tax return for Connecticut in 2015 correctly, thereby preventing delays or penalties.

How to Pay Your Connecticut Taxes

Once you've completed your Connecticut tax return for the 2015 tax year, it's essential to understand your payment options. Whether you owe taxes or need to make estimated payments, Connecticut offers several convenient methods for paying your taxes.

Electronic Payment Options

Paying electronically is the fastest and most secure way to submit taxes to the Connecticut Department of Revenue Services (DRS). Here are some options:

Direct Payment via Taxpayer Service Center (TSC):

The TSC is Connecticut's online portal for tax filing and payments. You can make direct payments using your bank account information. This method allows you to pay your taxes quickly and securely.
Steps:
- Visit the TSC website at www.ct.gov/TSC
- Select "Make a Payment."
- Enter your bank account details and the amount you owe
- Receive an immediate confirmation of payment

Credit or Debit Card Payment:

You can pay using a credit or debit card through the official payments website. While this method is convenient, the service provider charges a convenience fee.
Accepted cards include Visa, MasterCard, Discover, and American Express.

Electronic Funds Transfer (EFT):

You can make an EFT payment if you e-file your Connecticut tax return. This method allows you to transfer funds directly from your checking or savings account, with no additional fee.
Steps:
- During the e-filing process, select the EFT payment option
- Enter your bank’s routing and account numbers
- Select the account type (checking or savings) and submit the payment

Paying by Check

If you prefer to pay by check, ensure you follow the instructions carefully to avoid processing delays:

Make your check payable to the "Commissioner of Revenue Services."
Include your full name, Social Security number, and "2015 Form CT-1040" on the memo line.
Do not staple your check to your return; clip it to the front of your tax return.
Mail the payment to the appropriate address (depending on whether you’re including payment or not):

With payment:

Department of Revenue Services
PO Box 2977
Hartford, CT 06104-2977

Without payment:

Department of Revenue Services
PO Box 2976
Hartford, CT 06104-2976

Payment Deadlines

It's essential to submit your payment by the filing deadline to avoid penalties and interest:

The filing deadline for the 2015 tax year was April 18, 2016.
Estimated tax payments were due on the following dates:
- April 15, June 15, September 15, and January 15 (for the next tax year).
If you file for an extension but owe taxes, you must still pay by the original filing deadline to avoid late fees and interest.

Penalties for Late Payments

If you fail to pay your taxes on time, you may incur:

Late Payment Penalty: 10% of the tax not paid by the due date.
Interest: 1% per month or fraction of a month on unpaid tax.

If you cannot pay the full amount by the deadline, it's still advisable to file your return on time and pay as much as possible. This will minimize penalties and interest. If needed, you can contact DRS to discuss options for paying the balance over time.

How to Track Your Connecticut Tax Refund or Balance Due

Once you file your Connecticut tax return electronically or by mail, you should track your refund or determine if you owe any additional taxes. The Connecticut Department of Revenue Services (DRS) offers several ways to monitor the status of your tax return and balance due.

Tracking Your Refund

If you're due a refund, Connecticut offers convenient options to track its status:

Online:

The Taxpayer Service Center (TSC) is the easiest way to track your Connecticut refund online.

Steps:
- Visit www.ct.gov/TSC
- Under the "Individuals" section, click on "Where's My Refund?"
- Enter your Social Security number, tax year, and expected refund amount to check the status of your refund.
- This system is available 24/7, so you can check it at your convenience.

- Have your Social Security number ready, as it’s needed to access your refund status.

Refund Processing Times

Processing times for your refund depend on how you filed your return:

Electronic Filing with Direct Deposit: Refunds are typically issued within 5-10 business days.
Electronic Filing with Paper Check: Refunds generally take 4-5 weeks.
Paper Filing: If you filed on paper, expect a processing time of 8-10 weeks for both direct deposit and paper check refunds.

Note: First-time filers are not eligible for direct deposit refunds due to security measures to prevent refund fraud.

Delayed Refunds

There could be several reasons for the delay in your refund.

The Connecticut Department of Revenue Services selects your tax return for additional review.
There are errors or missing information on your return.
You owe other taxes to Connecticut or have unpaid debts subject to collection.
Incorrect banking information for direct deposit.

If it has been over 12 weeks since you filed and you still haven’t received your refund, contact the DRS at 860-297-5962 for assistance.

Checking Your Balance Due

If you owe additional taxes or want to check the balance on your account:

Log in to the Taxpayer Service Center (TSC) and view your account summary and payment history.
You can make payments directly through the TSC if you have any outstanding balance.
You can also set up payment plans for outstanding balances and contact DRS for assistance.

Standard Deductions and Credits for Connecticut Tax Filers

When filing your Connecticut tax return, taking advantage of available deductions and credits can significantly reduce your tax liability. Understanding these options is critical for making sure you're not overpaying. This section will cover the most commonly used Connecticut tax credits and deductions for the 2015 tax year.

Property Tax Credit

One of the most beneficial credits available to Connecticut residents is the Property Tax Credit:

Eligibility: This credit is available for property taxes paid on your primary residence and motor vehicles. The maximum credit is $300 for the 2015 tax year.
Income Limitations: The amount of the credit decreases as your Connecticut adjusted gross income (AGI) increases. For example:
- Single filers: Full credit available for an AGI of $47,500 or less, phased out between $47,501 and $64,500.
- Married Filing Jointly: Full credit is available for an AGI of $100,500 or less, phased out between $100,501 and $120,500.
Filing Requirements: To claim this credit, complete Schedule 3 and attach it to your Connecticut income tax return.

Connecticut Earned Income Tax Credit (CT EITC)

The CT EITC is a refundable credit aimed at helping low- to moderate-income residents:

Eligibility: You must be a full-year Connecticut resident, have claimed the federal Earned Income Tax Credit (EITC), and meet income and investment limitations.
Calculation: The Connecticut EITC is 27.5% of the federal EITC amount. For example, if your federal EITC is $1,000, your CT EITC would be $275.
Benefits: This credit can result in a refund, even if you owe no taxes.

Military Retirement Pay Exemption

For 2015, military retirement pay is fully exempt from Connecticut income tax:

This is a significant benefit for military veterans and retirees, as it can reduce or eliminate any tax liability associated with retirement pay.
To claim this exemption, you must ensure that the appropriate military retirement income is reported on your return and follows the Connecticut Department of Revenue Services guidelines.

Teacher’s Retirement System Pension Exemption

If you’re receiving a pension from the Connecticut Teachers’ Retirement System, 10% of your pension income is exempt from Connecticut income tax for the 2015 tax year.
Reporting: Ensure you accurately report your pension income to claim this exemption.

Social Security Benefits Exemption

Social Security benefits are partially or fully exempt from Connecticut state taxes, depending on your income level.
A portion of Social Security benefits may be taxable for individuals with higher incomes. However, many taxpayers can still benefit from this exemption, significantly lowering their tax liability.

Other Deductions

Connecticut offers additional deductions to help reduce your taxable income:

Contributions to the Connecticut Higher Education Trust (CHET): Contributions to 529 college savings plans are deductible, which can help you save for educational expenses while reducing your current taxable income.
Federal Tax Deductions: Certain federal tax deductions, like charitable contributions and mortgage interest, may apply to your Connecticut return.

Review all available deductions and credits to ensure you’re not missing out on any you qualify for. Failing to claim them can mean paying more than necessary.

How to File for an Extension If You Need More Time

You can request an extension if you cannot complete your Connecticut tax return by the filing deadline. However, it’s important to note that an extension to file is not an extension to pay any taxes you owe. Here's what you need to know about filing an extension for your 2015 tax return.

For Individuals

If you need more time to file, you can request a six-month extension using Form CT-1040 EXT:

Filing Deadline: This form must be filed by April 18, 2016, the original due date for 2015 tax returns.
Payment Requirement: If you owe any taxes, you must estimate and pay them by the original deadline to avoid penalties and interest. The extension only allows you extra time to file your return, not to pay the tax due.
How to File: You can file Form CT-1040 EXT electronically through the Taxpayer Service Center (TSC) or by mail.
Extension of Time: You will have until October 15, 2016, to file your return. However, failure to pay by the original due date will result in interest and penalties.

For Pass-Through Entities

If you are filing on behalf of a partnership, S corporation, or LLC, you can file an extension using Form CT-1065/CT-1120SI EXT:

Filing Deadline: This extension must be filed by April 15, 2016, for the 2015 tax year.
Extension Duration: This extension gives you an additional five months to file, with the new filing deadline being September 15, 2016.
Electronic Filing: For pass-through entities, the extension must be filed electronically, unless a waiver is granted.
Payment of Taxes: Similar to individual filings, you must make any estimated payments by the original filing deadline to avoid interest and penalties.

Important Notes

No Extension for Payments: Even if you file an extension, estimate and pay any taxes owed by the filing deadline to avoid late payment penalties and interest.
Filing Without an Extension: If you don’t file for an extension, you may be penalized for late filing and payment.

Filing an extension can give you peace of mind if you need more time to gather your documents, but remember that paying on time is critical to avoid additional charges.
