Keeper files the return. Contha is what the return is prepared from.
Keeper is tax filing with deduction finding and human review, priced by the year: Standard $199, Premium $399, Business $1,199. It computes quarterly payments, itemises Schedule C deductions, handles K-1s on Premium and S-corp and partnership filing on Business. It is not a ledger and does not carry your personal net worth. The two are complementary, and this page says where each stops.
