What does the Maximum Refund Guarantee refer to?

Line uses ColumnTax to help you file your taxes. If you get a refund higher than that estimated by us from any other tax return preparation provider, ColumnTax will reimburse you for up to $250*.

 *To be eligible for such reimbursement, the difference must be solely due to calculations, and not from entering any additional information or taking any different tax positions. To be eligible for such reimbursement, you must file your federal (and if applicable state) income tax returns using the other tax preparation provider and must submit a copy of such return within sixty (60) days of filing, via letter to 228 Park Ave S, PMB 22299, New York, New York, 10003, US or via email to support@columntax.com. You must also provide proof of payment for the other tax preparation provider and Column Tax will reimburse you for that amount (up to $250). Column Tax reserves the right to request additional information to support your claim that the other tax preparation provider calculated a lower tax liability or larger refund amount and that any such difference was not the result of different information.
