mortgages already send reports to IRS. System could be set where IRS send an estimate and tax payer either pays/agrees for refund, or send back updated one with deduction and supporting documentation for these deduction. I own a house, do freelancing, investment done in retirement accounts, HSA accounts. Except business expenses, everything else was already reported to IRS either by bank, or employer or client on 1099-MISC. If there would be a form I could just sign and send back - I probably would skip expenses completely in this year. And for majority of people I feel like there would be nothing to report what already is not reported.
