I have both worked for H&R Block and used their software for over 10 years. I had always recommend both their offices and their software, even after last year, when we discovered there was a software glitch that was miscalculating self employment taxes, which changed my sister's refund from $5900 to $3800 after the IRS re-calculated the H&R Block software error. I kept my faith in H&R Block until this year when the same mistake from last year happened again.
I did both my sister's and my return by hand while also completing tax prep with H&R Block software to make sure that last years problem did not happen again. Well it did and I immediately contacted H&R Block to inform them it was still a problem. Unaware that another of my sisters had already filed her return using H&R Block software to end up paying Efiling fees for an 8 to 15 day return, which ended up taking 6 weeks, with no refund of her Efiling fees and a return of $2900 verses $3509 that H&R Block software had stated she would receive.
H&R Block agreed they had a program error that they were releasing an update on Feb 11, 2010 to correct this glitch. I waited to an additional 3 weeks to file both mine and my other sister's return for the update to be released and installed before I completed our returns. Even after this update, my sister's return stated she would get $6800 back, but after Efiling and paying the Efiling fees, she did not get her return in 8 to 15 days, she got her return in a month, and the return was $4400 with the explanation that there was calculation error.
This has created many issues because H&R Block software advertises they guarantee accurate returns, but when you call them on this guarantee, their answer is to refund you the money you paid for their program. Oh and lets not forget their useless apologies.
