I highly recommend Tony Du. He makes the hard easy without making the easy hard! Every year I break out in a cold sweat just knowing that April 15 is coming—and my taxes are pretty straightforward. Enter Tony Du. With 30 years experience and on-going education, Tony is spot-on regarding both simple and complex tax law. He unraveled a big mistake I made in a previous tax year that was collecting penalties practically by the minute. He filed my corrected tax forms ASAP which stopped the penalties! I’m so grateful for him. Check him out. 👍👍👍👍👍
