My late husband did ours the first year we were married back in 1964. We got audited, and he had made so many mistakes it was unbelievable. Some were in our favor, some in the IRS favor, and it came out about a wash. But we reached the conclusion that after that we would have them done by a CPA. Our taxes became increasingly complex. One year the CPA charged us $1800 to have them done, and even then I found he had made a couple of major errors, so had to take them back to him and have him re-do it. Our taxes have been at times 28 pages long! But last year I decided to do them myself with Turbo Tax and save the money. They were still 16 pages in length, as I have various investments and deductions and my part-time home business, but it saved me about $350.
