Frequently Asked Questions About LGL-001
LGL-001 has a Form Complexity Index of 46 out of 100, placing it in the moderate complexity tier. This score is calculated deterministically from the form’s own structure using Instafill’s published Form Complexity Index methodology, so it can be reproduced and independently verified — it is not a subjective estimate.
For LGL-001 specifically, the score reflects 43 fillable fields across 1 page, grouped into 9 sections, plus 1 page of printed instructions. The number of fields is the largest factor in the base score (weighted 36%), followed by how difficult those fields are to complete based on their type, where free-text and signature fields count for more than simple checkboxes (26%). The number of pages that actually contain fields (15%), the amount of conditional “fill-only-if” logic (16%), and how many sections the form is divided into (7%) account for the rest of the base. On top of that base, the index adds points for tables and repeating lists, bundled instruction pages, and dense page layouts — capturing difficulty the base alone can miss.
In practical terms, a moderate score means the form takes real effort: there are enough fields, pages and rules that errors are easy to make by hand. Instafill removes that effort entirely: our AI reads your information, maps each value to the correct field — including the conditional ones — and completes LGL-001 accurately in under a minute, with every field available for you to review before you download.

Compliance LGL-001
Validation Checks by Instafill.ai
1
Validates Taxpayer and Spouse Social Security Number Format
This check ensures that the Social Security Number (SSN) for both the taxpayer and spouse, if provided, is a valid nine-digit number. It should reject entries with non-numeric characters, incorrect length, or invalid patterns like all zeros. This is crucial for correctly identifying the taxpayer and linking the Power of Attorney to the correct tax account, and failure to provide a valid SSN will prevent the form from being processed for individual taxpayers.
2
Ensures Correct Identifier for Taxpayer Entity Type
This validation verifies that the correct identification number is provided based on the taxpayer's entity type. If the taxpayer is an 'Individual,' the Social Security Number field must be completed, while the Federal Employer Identification Number (FEIN) should be blank. Conversely, if a business entity (like Corporation, Partnership, LLC) is selected, the FEIN must be provided. This logic prevents misidentification of the taxpayer and ensures the POA is applied to the correct business or individual account.
3
Validates Conditional Requirement for Spouse Information
This check confirms that the 'Spouse’s Full Name' and 'Spouse’s Social Security Number' fields are only completed when the Power of Attorney pertains to a joint 'Personal Income Tax' or 'Individual Use Tax' matter. If these tax types are not listed in Part III, the spouse's information should be blank. This prevents the unnecessary collection of sensitive personal information and ensures the form complies with its own instructions, avoiding processing errors or rejections.
4
Requires Specification for 'Other' Entity Type
This validation ensures that if the 'Other (specify)' checkbox is selected in Part I, the corresponding text field for the entity type is not empty. Conversely, if the 'Other' checkbox is not selected, the text field must be empty. This rule guarantees that the specific entity type is captured when a standard option is not applicable, which is essential for correct legal and tax processing.
5
Confirms Only One Representative is Designated to Receive Notices
This check verifies that a maximum of one 'Representative to receive copies of DRS notices' checkbox is selected across all listed representatives in Part III. The form instructions state to 'Check one box only' for this designation. This is important to create a single, unambiguous point of contact for official communications, preventing confusion and ensuring notices are sent to the correct party.
6
Ensures All Required Fields for Each Representative are Complete
This validation confirms that for every representative listed in Part III, their full name, firm name and address, and telephone number are all provided. Leaving any of these fields blank for a listed representative makes the entry incomplete and unusable. This check is critical for the DRS to be able to identify and contact the authorized representative, and failure will result in an incomplete and invalid POA.
7
Verifies At Least One Power is Granted in Part II
This check ensures that at least one of the checkboxes for the powers granted (e.g., 'Sign returns,' 'Represent the taxpayer') is selected in Part II. A Power of Attorney form that grants no specific authority to the representative is legally meaningless and serves no purpose. This validation prevents the submission of an invalid form that would be rejected by the DRS.
8
Requires At Least One Tax Matter to be Specified
This validation ensures that at least the first row for 'Tax Type' and 'Year(s) or Period(s)' in Part III is completed. The Power of Attorney is only valid for the specific tax matters and timeframes listed. Submitting a form without this information would make it ambiguous and unenforceable, as it would not be clear what authority is being granted.
9
Validates Presence and Format of Signature Dates
This check verifies that the 'Taxpayer Signature Date' is present and in a valid MM/DD/YYYY format. It also checks that if the 'Spouse’s Printed Name' field is filled, the 'Spouse Signature Date' is also present and correctly formatted. The signature date is a critical legal component that establishes when the authority was granted, and its absence or incorrect format can invalidate the entire document.
10
Matches Taxpayer's Declaration Name with Part I Name
This validation cross-references the 'Taxpayer’s Declaration Print Name' in Part II with the 'Taxpayer’s Name' in Part I. The names must match to confirm that the person signing the declaration is the same taxpayer granting the power. This is a key control to prevent unauthorized individuals from executing the Power of Attorney, protecting against fraud.
11
Validates Representative's Telephone Number Format
This check ensures that the telephone numbers provided for representatives in Part III adhere to a standard 10-digit format, such as NNN-NNN-NNNN. It should validate the presence of 10 digits and optionally enforce the hyphenated format for readability. Correctly formatted contact information is essential for the DRS to be able to communicate with the representative without issue.
12
Validates 'Taxpayer's Title' Field for Business Entities
This validation rule checks that if the taxpayer entity type selected in Part I is a business (e.g., Corporation, Partnership, LLC), the 'Taxpayer’s Title or Position' field in Part II is filled out. Conversely, if the entity type is 'Individual,' this field should be blank. This ensures that for business entities, the authority of the signatory is clearly stated, which is a legal requirement for corporate acts.
13
Validates Format of 'Year(s) or Period(s)' Field
This check ensures that the entry in the 'Year(s) or Period(s)' field follows one of the accepted formats, such as a single year (YYYY), a date range (MM/DD/YYYY–MM/DD/YYYY), or a monthly range (MM/YYYY–MM/YYYY). This structured data is necessary for the system to correctly apply the POA to specific tax periods in the taxpayer's record, preventing misapplication of authority.
14
Verifies Completeness of Tax Matter Rows
This validation ensures that if a 'Tax Type' is entered in any row in Part III, the corresponding 'Year(s) or Period(s)' field in the same row must also be completed. An entry with a tax type but no period is incomplete and ambiguous. This check prevents partial entries that would cause processing errors and require manual intervention.
Common Mistakes in Completing LGL-001
Filers often enter vague information like "All taxes" or "2020-Present" in Part III, instead of the specific tax types and periods required. This happens because they want to grant broad authority but the form requires precision for legal validity. An imprecise submission can be rejected by the DRS or may fail to cover the intended tax issue, requiring a new form to be filed. To avoid this, list each specific tax type (e.g., "Sales and Use Tax," "Personal Income Tax") and the exact years or period ranges (e.g., "01/01/2022-12/31/2023") as separate line items.
A power of attorney is frequently invalidated due to signature errors, such as only one spouse signing for a joint tax matter, or an unauthorized employee signing for a corporation. This occurs due to a misunderstanding of who has the legal authority to bind the taxpayer. An invalid signature renders the entire document void, causing significant delays and preventing the representative from acting. Always ensure that for joint returns both spouses sign, and for entities, an authorized officer, partner, or member signs and includes their title.
Taxpayers sometimes complete and sign the form but neglect to check the boxes in Part II that grant specific authorities, such as the power to "Sign returns" or "Execute waivers." This mistake essentially appoints a representative with no power to perform the necessary actions, defeating the purpose of the form. To prevent this, carefully review each checkbox in Part II and select all authorities you intend to grant your representative for the specified tax matters. This ensures they can fully act on your behalf without needing further authorization.
People frequently confuse which identification number to use, for instance, entering a Social Security Number (SSN) for a corporation or a Federal Employer Identification Number (FEIN) for an individual. This error happens when rushing or being unsure of the entity's filing requirements. Using the wrong identifier will cause the form to be rejected or fail to match with the taxpayer's account at the DRS. Always use the SSN for individuals and sole proprietors, and the FEIN and/or Connecticut Tax Registration Number for business entities, trusts, and estates.
A common error is checking the wrong box for the taxpayer's entity type in Part I, such as a single-member LLC checking "Sole proprietorship" instead of "Limited liability company." This confusion arises from the similarities in how different entities are taxed or operated. An incorrect entity selection can lead to questions about the signatory's authority and cause processing delays. Carefully review the legal structure of the taxpayer and select the precise corresponding box on the form.
Filers may mistakenly enter their representative's address in the taxpayer mailing address section in Part I, thinking it will direct all correspondence to their agent. However, the form instructions explicitly forbid this, as the DRS must maintain the taxpayer's official address of record for official mailings. This error can lead to missed notices and complications in updating official records. Always use the taxpayer's own valid mailing address in Part I and use the checkbox in Part III to designate a representative to receive copies of notices.
When appointing multiple representatives in Part III, filers sometimes check the "Receive copies" box for more than one person, contrary to the form's instruction to "Check one box only." This mistake creates ambiguity for the DRS, which may result in notices being sent to only one representative at random, or processing being delayed while clarification is sought. To ensure clear communication, decide which single representative should be the primary recipient of copied correspondence and check only the box next to their name.
Simple data entry errors, like entering a date as '9-23-23' instead of '09/23/2023' or omitting dashes in a phone number, are extremely common. These mistakes occur from not following the specified format for each field, which can cause the form to be rejected by automated processing systems or lead to data corruption. To avoid this, pay close attention to format examples like (MM/DD/YYYY) or (NNN-NNN-NNNN). AI-powered tools like Instafill.ai can help prevent these errors by automatically formatting data correctly as you fill out the form.
An individual taxpayer filing for themselves sometimes fills in the "Title" field in Part II with something like "Mr." or "Taxpayer," when this field should be left blank. This field is exclusively for individuals signing on behalf of an entity, to specify their official capacity (e.g., "President," "Partner," "Trustee"). This error creates confusion about the filer's status and can slow down verification. Individual taxpayers should always leave the "Title" field empty.
When filing electronically via myconneCT, users must upload a completed LGL-001, but they sometimes upload a blank form or one that hasn't been physically or digitally signed. This happens when they misunderstand that the form must be completed and signed *before* uploading. An unsigned or incomplete form is invalid and will be rejected, halting the power of attorney process. To avoid this, ensure the PDF is fully filled out and properly signed before starting the upload process on the portal. If the form is a non-fillable PDF, a tool like Instafill.ai can convert it into a fillable version to ensure all fields are completed cleanly before printing and signing.
