Questions
Aiwyn Tax, with SPIRITT.
01What can SPIRITT calculate with Aiwyn Tax?+
Federal and state returns for the supported years and jurisdictions, from inputs SPIRITT builds for you.
02Which forms does it cover?+
Each supported form has an input namespace, such as the 1040, Schedule C and state returns like California's 540.
03Does it catch input mistakes first?+
Yes. It checks inputs against the schema and fixes or reports each validation error before calculating.
04Can it produce a return PDF?+
Yes. It generates the PDF in the background and fetches the download link when it is ready.
05Can it model what-if scenarios?+
Yes. Filing status, contributions, new income or a move can each be recalculated side by side.
06What does the connection need?+
Aiwyn Tax connects without a separate account key. Books, payroll and intake apps connect separately.
