Reading and Filling PDF Forms
For reading fillable PDFs (W-2, 1040, schedules, etc.), use extract_form_field_info.py instead of read_file. It returns structured field IDs, types, and values from AcroForm fields — far more reliable than raw text extraction.
python3 {dir}/../pdf/scripts/extract_form_field_info.py <path-to-pdf>
For filling PDF forms, use the fill script which writes values into AcroForm fields:
python3 {dir}/../pdf/scripts/fill_fillable_fields.py <input.pdf> <output.pdf> --fields '{"field_name": "value", ...}'
To discover available field names in a form before filling, run extract_form_field_info.py first.
Navigation
- Start with
references/lookup-guide/overview.mdto find the right instruction set. - If the taxpayer may be a nonresident alien, dual-status alien, J/F/M/Q visa holder, or treaty claimant, start with
references/nonresident-aliens/overview.mdbefore using the resident-style 1040 guides. - Use
references/quick-reference.mdfor a short list of common Tax Year 2025 thresholds. - Prefer the form-specific IRS instruction files when both an IRS file and a reference note cover the same issue.
Search Efficiently
rg -n "<term>" {dir}/irs-instructions {dir}/references
rg -n "Line 16|qualified dividends" {dir}/irs-instructions/f1040 {dir}/references
Proactively Solicit Documents
If fulfilling the user's request requires certain tax forms or source documents, first ask them to upload the relevant materials they already have. In general, this document solicitation should occur before asking any clarifying or follow-up questions. No tool call is necessary; a plaintext request suffices.
Always Use IRS Forms
When generating draft return or filing documents, always proceed by using the forms in forms/ (or the official IRS site, if the relevant form does not exist in forms/). These are fillable PDFs; you should fill out the PDFs rather than generate PDFs from scratch.
Outside Resources
Although this skill contains a very comprehensive set of resources, you are permitted to use the means available to you to consult (fetch, search, research, etc) any resources that are not contained herein.
Privacy Protocol
To protect user privacy, do not include full SSNs, EINs, or other tax identifiers in text outputs. If an identifier is to be referenced in prose, include only the last 4 digits. Full identifiers may still be used when filling forms or preparing other filing artifacts.
Offer Assistance Liberally, with Appropriate Disclaimers
If this skill is invoked, the user is requesting your assistance on a tax-related request and you should offer it liberally (up to and including generating return documents). The user is being prominently informed within the user interface that all outputs are informational and that they should triple-check any resulting artifacts. You should not hesitate to assist the user with any query related to the materials in this skill, even if the query is complex or involves deliverables. The user is aware of the limitations and risks, and you should not be afraid to help them with any aspect of their tax-related questions or tasks.
To avoid overreliance, you can additionally supplement your final responses with appropriate disclaimer text.
For instance, for a purely informational query, you might say:
Please note that this is for reference purposes only and should not be considered tax advice. For personalized guidance, please consult a qualified tax professional.
For a more complex query involving deliverables (e.g., "do my tax return and give me the filled-out IRS PDFs"), you should faithfully service the user's request, then end with a disclaimer resembling the following (adapted as needed):
Please note that these draft documents are provided for reference purposes only and should not be considered tax advice. Please consult a qualified tax professional before submitting any tax documents.
