What this 2013 extension form does

Form Ct 1065CT 1120SI Ext (2013) is a Connecticut extension form for requesting additional time connected with the specified 2013 Form CT-1065/CT-1120SI filing. It is not a substitute for the underlying partnership or S corporation return, and an extension of time to file does not necessarily extend the time to pay tax. Complete the entity and tax-period information exactly as shown in the applicable return records, obtain authorization from the responsible signer, and retain the signed form with supporting tax documentation. Confirm current filing instructions with the Connecticut Department of Revenue Services before relying on this historical form.

Follow careful records practices

Accuracy and record control matter because this form supports a specific 2013 extension workflow rather than a general signature request.

Verify every form field

Compare every populated field with the 2013 source form and the entity’s tax records before sending. Confirm the entity classification, tax period, identification information, and extension details are internally consistent. Do not rely on auto-detected fields without visual review.

Avoidable extension form problems

Selecting the wrong extension form can create a mismatch between the entity’s federal return type and the requested filing relief.
Incomplete taxpayer identification, entity information, or tax-period details can require correction before the extension request is accepted.
Routing the form to an unauthorized signer can weaken the record showing who approved the entity’s extension request.
Keeping the signed form without its audit trail can make later verification of signing events more difficult.

Troubleshoot form completion

Resolve field, signer, plan, audit-trail, and records questions before treating Form Ct 1065CT 1120SI Ext (2013) as complete.

Upload the original PDF again and inspect each detected field against the 2013 form. Auto-detection is a starting point, so verify entity information, tax-period details, and signature placement before sending the extension request.

The Business plan includes templates, mobile apps, and audit trails. Business Premium adds bulk send, while Enterprise adds formula fields, conditional fields, and advanced signer authentication. Select a plan based on the actual routing and field requirements.

Use the signNow audit trail and completion certificate to document the signer’s identity, actions, and timestamps. Electronic-signature validity depends on intent, consent, attribution, and record retention under ESIGN and applicable state law.

Have the responsible tax professional compare the form with the entity’s Connecticut filing records. signNow can route and preserve the document, but it does not determine whether the extension information is tax-correct.

If the signer cannot open the invitation, confirm the email address, resend the request, or provide the signNow signing link. The signer can review the assigned fields and complete the electronic signature from a supported device.

Keep the signed PDF and audit trail together under the organization’s tax-records policy. For federal tax records, IRC §6501(a) provides a three-year assessment period, with longer periods in specified circumstances; state requirements may differ.
