The cost of tax software programs varies based on the type of program that you choose and your needs. If you have a simple tax return, you may be able to file your taxes for free with a program like Credit Karma Tax. However, if you have a more complex return, you might be better off with a tax software like Jackson Hewitt, which offers lots of features and real-time access to customer support. Programs can range from completely free to upwards of $120 for federal tax filing, depending on which option you choose.
