Connecticut Earned Income Tax Credit
Recordkeeping Requirements for Self-employed Persons

If you claimed the Connecticut Earned Income Tax Credit (CT EITC) on Form CT-1040, Connecticut Resident Income Tax Return, or Form CT-1040X, Amended Connecticut Income Tax Return for Individuals, and you are self-employed, DRS may ask you to provide business records to prove the amount of income and expenses claimed on your Connecticut income tax return. DRS will use the information to confirm that you are entitled to the CT EITC.

It is important that you maintain good business records. If you do not keep records, or if your records do not support what you reported on your return, your CT EITC claim may be denied.

Are you Self-employed?

You are self-employed if you:

  • Carry on a trade or business as a sole proprietor;
  • Are an independent contractor;
  • Are a member of a partnership;
  • Are a member of a limited liability company; or
  • Are in business for yourself in any other way.

Self-employment can include work in addition to your regular, full-time job. This could include part-time work you do in or outside your home.

How to Keep Good Records

As a general rule, you should maintain records of your business transactions – payments, purchases, etc.

Maintain a Daily Log

Keep daily records of all your business transactions.

  • Provide detailed information about each transaction; and
  • Update your records every time you make a purchase, pay an expense, make a sale, or receive a payment.

You may keep a log book or computer log. For examples of a daily log, see Sample Logbook Entries.

Keep Receipts and Other Documents

Keep all documentation that supports each entry in your log, such as:

  • Copies of checks or money orders that you received as payments, or used to pay expenses;
  • Advertisements;
  • Receipts and invoices for payments you made; and
  • Credit card statements and receipts.

Use a Bank Account

Having a bank account can help establish your income, particularly if you receive payments by check. Keep copies of deposit slips, cashed checks, and bank statements.

Keep Records for at Least Three Years

DRS may request your business records for up to three years after you file your return.

Review Process

DRS will send you a notice if it needs copies of records to confirm the amounts reported on your return. Do not ignore the notices or letters. If you do not respond, your claim for the CT EITC will be denied.

Make sure the information you submit is accurate and supports what you claimed on your return. Inconsistent or incomplete information may result in the denial of your CT EITC claim.

Some examples of inconsistent information that may cause DRS to deny a CT EITC claim are:

  • Taxpayer claimed that he or she was a book seller, but receipts for expenses were unrelated to book selling.
  • Taxpayer stated that he or she received approximately $200 per week in cash as a housekeeper but provided no supporting documentation.
  • Taxpayer submitted a sworn statement that he or she provided child care services, but did not submit any other documentation.

An example of supporting information that would result in DRS approving a CT EITC claim is:

  • A taxpayer submits a list of clients and a logbook of earnings with copies of receipts, canceled checks, and bank statements to support a claim of receiving income from providing child care services.

If Your Claim for a Credit is Denied: If, after reviewing the information you submitted, DRS denies your claim, you may file an appeal within 60 days of the notice of determination with the DRS Appellate Division by completing Form APL-002. For more information about Form APL-002, visit the DRS website.
