April 3, 2026

To extract data from 1040 tax returns, upload the PDF or scanned form to an AI extraction tool like Lido. It reads filing status, income sources, adjustments, deductions, credits, and tax liability from any 1040 variant (1040, 1040-SR, 1040-NR) with 99.9% accuracy.

CPA firms, tax preparers, and financial institutions routinely need structured data from 1040 returns. Firms preparing amended returns need data from the original filing. Lenders use 1040 data for income verification. Auditors review returns as part of individual tax compliance engagements. Each 1040 is 2 pages but the attached schedules can add 10-20 more.
