Keeping Your Storage Unit Receipts Straight
Knowing storage unit qualifies is the easy part. Proving it eleven months later, from a receipt that faded in your glovebox, is where this deduction usually gets lost. Photograph the receipt when you get it and TaxTidy reads the vendor, the amount and the date off it in about three seconds, then files it under Schedule C, Line 20b — the same line you'll claim it on.
The documentation checklist above is the part most people only think about in April. Your Audit Readiness Score keeps it in front of you all year: it counts the expenses with no receipt attached, the ones still sitting uncategorized, and the ones missing a date or a vendor name. You see the gaps while you can still fix them.
