Yes. You can enter flights for any date and generate apportionment reports for any tax year. Prior-year catch-up entry is a common use case.

Most states that impose a corporate income or franchise tax require some form of apportionment for aircraft. The majority use a mileage-based factor (total or revenue miles). Florida uses a statutory boundary called the FL Box (§220.151). California uses a weighted formula based on block-to-block air time and arrivals & departures (Cal. Code Regs. §25137-7). New York uses a three-factor arithmetic average of arrivals & departures, revenue tons, and originating revenue (Tax Law §210-A(7)(b)). Our software includes dedicated reports for Florida, California, and New York, plus mileage reports for all other states. Consult your tax advisor for state-specific requirements.

No. AircraftTaxSoftware.com is purpose-built for state mileage apportionment — calculating what percentage of aircraft miles were flown in each state. SIFL, Section 274 entertainment and commuting disallowance, and 280F depreciation qualified business use calculations are separate tools. Our affiliate site AircraftTaxSolutions.com handles all of those.
