Instafill.ai has reached a new milestone by automating Ireland’s official Form 11 – Tax Return and Self-Assessment 2024 – a 44-page government PDF containing 3,885 fillable fields. This is the largest and most complex form we have processed to date.

This is nearly eight times larger than the typical complex forms we handle, which range from 300 to 500 fields.

Time savings
Filling out Form 11 manually typically takes 4 to 6 hours for a tax professional familiar with the document. Instafill.ai completes it in under 10 minutes – a time reduction of over 96%. For high-volume practices processing dozens of returns during tax season, this represents hundreds of hours saved.
What this means
People often ask about limits. While we have discussed page counts and file sizes, we hadn’t explicitly addressed field count – because we hadn’t encountered a form this large. Form 11 has now set that benchmark. If your forms fall below this threshold, they are within Instafill.ai’s proven range.
| Our AI successfully mapped all fields, understood the logic between them, and fine-tuned the entire document. This isn’t just a technical achievement – it’s proof that Instafill.ai can handle even the most demanding real-world government forms. |
Key highlights
- 📄The original Form 11 had no interactive fields. Instafill.ai converted it into a fully fillable PDF
- 🎯Our AI accurately maps data across thousands of fields in a consistent, error-resistant way without requiring manual workarounds
- 📈This achievement shows Instafill.ai’s ability to handle forms ranging from routine documents to large, complex government PDFs
Your takeaway
If you work with complex multi-page forms – credentialing packets, compliance documents, government applications, or financial disclosures – Form 11 demonstrates that Instafill.ai reliably handles high field counts.
