My taxes are easy this year. I'm done. Just need to plug numbers into appropriate space. My medical expenses and sales tax exceeded income so don't even need donation write offs. Will save those for future years....
And yes, donations from lockers are limited to what you paid for the unit. Which is messed up because if you pay $100 for a unit that has $1000 TV you donate, write off can only be $100. But you pay $100 for a unit that has $100,000 cash in it....you pay income tax on $99,900 of it.
Tax laws changed again. Any donations over $500 need to be itemized. At least snap photos as you unload so you have proof......
Nice little program (they now have an app, too). You can print it out for your taxes or if you use turbotax it will import it for you....
