About

Flight Tax Systems is a web-based aviation tax software application built by aviation and aircraft tax experts to automate flight tracking and tax reporting for business aircraft, eliminating reliance on complex spreadsheets and reducing the risk of errors. It captures and organizes flight data to support IRS-compliant reporting, including Standard Industry Fare Level (SIFL) fringe benefit calculations, cost disallowance reporting, 280F business-use tracking for depreciation recapture, and state sales, use, and property tax reporting with state-specific modules. It also includes SEC incremental cost reporting, cost center tracking to allocate flight costs across departments or projects, and electronic flight data import from scheduling systems to save time and reduce manual entry. Additional capabilities include document uploads for contemporaneous recordkeeping, customizable flight categories, Excel export, audit substantiation reports, unlimited aircraft and users.

About

Lineaum OS is a business aviation platform that brings the entire commercial journey into one connected workflow, helping teams capture demand, source aircraft, quote clients, automate documents, collect payments, and track revenue without juggling inboxes, spreadsheets, and disconnected tools. A branded lead-capture widget turns a website into an always-on sales channel, feeding enquiries directly into the pipeline while keeping client ownership inside the business. Teams can source across more than 30,000 aircraft from over 10,500 operators, send quote requests, track operator responses, and generate client-ready quotes faster. It also automates contracts and invoices, supports connected payment workflows, and provides visibility into pipeline, booked value, revenue, and commissions. Lineaum organizes the sales process into clear stages, from capturing the first enquiry and finding the right aircraft to closing the booking and receiving payment.
