Morning: Small Business Tax Tips (New Haven): Receipt Retention, How Long New Haven Business Owners Should Keep Records

NEW HAVEN, CONNECTICUT, Jose’s Tax Service, September 22, 2026

Small business owners should establish a formal record-retention policy before year-end. Receipts, bank statements, payroll files, asset documents, and filed tax returns support deductions and demonstrate how reported figures were calculated.

Missing documentation can result in disallowed deductions, delayed processing, additional tax, interest, and penalties. The correct retention period depends on the record, the tax involved, and the circumstances of the return.

This guide explains the principal federal rules and Connecticut-focused steps for New Haven business owners.

Know the Federal Retention Rules!

The Internal Revenue Service (IRS) generally requires taxpayers to retain records that support income, deductions, and credits until the applicable period of limitations expires. The following rules apply in common situations:

1. Keep ordinary income-tax records for at least three years.

   • Retain receipts, invoices, bank records, and supporting documents for at least three years after the return is filed.
   • If the return is filed before its due date, the IRS generally treats it as filed on the due date.
   • Keep records longer if another rule applies.

2. Keep records for six years when income is substantially underreported.

   • The six-year period generally applies when more than 25% of gross income that should have been reported is omitted.
   • Documentation supporting sales, deposits, payment-platform income, and other revenue should be preserved carefully.

3. Keep records indefinitely when no return is filed or fraud is involved.

   • The IRS does not impose a regular limitation period when a return has not been filed.
   • A fraudulent return may also be examined without the standard three-year limitation.
   • Permanent retention is appropriate for records connected to these circumstances.

4. Keep employment tax records for at least four years.

   • Employment tax records should be retained for at least four years after the tax becomes due or is paid, whichever is later.
   • This includes payroll registers, time records, Forms W-2 and W-3, Forms 941 and 940, payroll-service reports, and documentation supporting tax deposits.

5. Keep certain loss-related records for seven years.

   • The IRS generally identifies a seven-year period when a business claims a bad debt deduction or a loss from worthless securities.

Review the IRS guidance in “How long should I keep records?” and Publication 583, Starting a Business and Keeping Records.

Use a Record-Retention Schedule!

A written schedule prevents premature disposal and unnecessary storage. Apply the following framework to the records most businesses maintain.

Receipts and invoices

Keep receipts and invoices for ordinary business expenses for at least three years after the related federal return is filed. Retain them for six years when they support sales-tax reporting, involve substantial income omissions, or relate to a transaction that may remain material.

Each receipt should identify:

• The purchase date.
• The vendor.
• The amount paid.
• The business purpose.
• The payment method.
• The applicable tax treatment.
• The related client, project, or property, when relevant.

A credit-card statement alone may not establish the business purpose of an expense. Keep the detailed receipt and a brief explanation.

Bank and credit-card statements

Retain business bank statements, credit-card statements, deposit records, canceled checks, merchant-processing reports, and payment-platform statements for at least three years. Use a six-year standard when records support Connecticut sales tax or when income reporting may be questioned.

Preserve monthly reconciliations with the statements. A reconciliation demonstrates that recorded income and expenses were compared with the financial institution’s records.

Payroll records

Keep payroll records for at least four years under the federal employment tax rule. Retain them longer if required by Connecticut employment, labor, insurance, or benefits rules.

Maintain:

• Employee names, addresses, and taxpayer identification information.
• Forms W-4 and Connecticut Form CT-W4.
• Payroll registers.
• Time sheets and wage calculations.
• Forms W-2 and W-3.
• Forms 941 and 940.
• Federal deposit confirmations.
• Connecticut Form CT-941 and Form CT-W3.
• Payroll-service reports and correspondence.

Payroll records should be stored separately from general operating receipts. Access should be limited because these files contain sensitive personal information.

Asset purchase documentation

Keep purchase invoices, financing agreements, titles, contracts, installation costs, improvement records, depreciation schedules, and disposal documents for business assets.

The IRS generally requires property records to be retained until the limitation period expires for the year in which the property is sold or otherwise disposed of. This includes records needed to calculate depreciation, amortization, adjusted basis, gain, or loss.

For major assets, retain the complete basis file permanently as a business policy. This is particularly appropriate for:

• Commercial real estate.
• Vehicles.
• Machinery and equipment.
• Building improvements.
• Computer systems.
• Long-term leasehold improvements.
• Assets received through an exchange or business acquisition.

Keep Certain Records Permanently!

A business should maintain permanent or long-term archives for records that establish historical tax positions, ownership, or asset basis.

Retain the following permanently when practical:

• Copies of filed federal and Connecticut tax returns.
• Final trial balances and year-end financial statements.
• Corporate, partnership, and LLC formation documents.
• Operating agreements and ownership records.
• Employer Identification Number (EIN) confirmation letters.
• Asset basis records and final depreciation schedules.
• Purchase and sale agreements for major business assets.
• Records of business acquisitions, mergers, reorganizations, and dissolutions.
• Documents supporting carryforward items that may affect future returns.
• Permanent loan, financing, and capital-contribution records.

Filed tax returns are useful when preparing future returns, responding to notices, applying for financing, or calculating an amended return. Keep the signed return, electronic acceptance confirmation, payment confirmation, schedules, and supporting workpapers together.

Apply Connecticut Sales Tax Rules Carefully!

Connecticut Department of Revenue Services (DRS) records should be maintained with particular care. DRS Informational Publication 2015(12), Getting Started in Business, states that sellers must keep accurate and complete records for at least six years.

For a New Haven business that collects or pays Connecticut sales and use tax, retain:

• Form OS-114, Sales and Use Tax Return.
• Sales invoices and receipts.
• Cash-register tapes and point-of-sale reports.
• Purchase invoices.
• Accounts receivable and accounts payable journals.
• General ledgers.
• Resale certificates.
• Exemption certificates.
• Records showing the disposition of items purchased for resale.
• Documentation supporting use-tax payments.
• Sales-tax reconciliation workpapers.

Connecticut’s general recordkeeping regulation and specific sales-tax guidance may apply differently depending on the tax, filing, transaction, and audit circumstances. The Connecticut statute of limitations and current CT DRS record requirements should be confirmed with a qualified tax professional.

Review current information through the Connecticut Department of Revenue Services and the Taxpayer Service Center.

Build an Audit-Ready System in New Haven!

Use a consistent process throughout the year. Do not wait until tax season to search through email, paper folders, and personal bank accounts.

1. Digitize receipts immediately.
   Scan paper receipts or save clear electronic copies. Use a file name that includes the date, vendor, amount, and expense category.

2. Separate business and personal accounts.
   Use dedicated business checking and credit-card accounts. Mixing funds makes substantiation more difficult and may weaken the presentation of otherwise valid deductions.

3. Record the business purpose.
   Enter a short explanation when the expense is recorded. For meals, document the attendees, business purpose, date, and location.

4. Reconcile monthly with bookkeeping records.
   Compare bank statements, credit-card statements, payment processors, payroll reports, and accounting software each month. Correct errors promptly.

5. Create folders by tax year.
   Use separate folders for income, expenses, payroll, sales tax, fixed assets, loans, tax filings, and correspondence.

6. Protect digital records.
   Use secure cloud storage, multi-factor authentication, controlled access, and regular backups. Keep a second backup in a separate location.

7. Prepare a year-end support file.
   Include the final bank reconciliation, accounts receivable and payable reports, inventory records, payroll summaries, fixed-asset additions, loan balances, sales-tax reconciliations, and copies of filed returns.

8. Retain records after closing the business.
   Closing a business does not immediately eliminate recordkeeping obligations. Preserve final returns, payroll documents, sales-tax records, asset files, and dissolution documents according to the applicable periods.

Watch the Filing Calendar!

Record retention supports timely filing. It does not replace filing obligations.

Connecticut sales and use tax returns reported on Form OS-114 are generally due on the twentieth day of the month following the reporting period. Connecticut withholding filings may have separate deadlines, including quarterly Form CT-941 deadlines. Federal estimated tax payments, payroll deposits, information returns, and income-tax returns have separate due dates.

Review the current federal and Connecticut filing calendars before each deadline. Late filing or payment may lead to penalties, interest, or delayed processing.

Practical reminder: Keep ordinary federal tax records for at least three years, employment tax records for at least four years, Connecticut sales-tax records for at least six years, and major asset-basis records for the life of the asset and beyond. Do not discard documents connected with an unfiled or potentially fraudulent return. Confirm Connecticut-specific requirements with a professional before destroying records.
