We began using Mr. Sunoko Lin as our CPA in January 2022 for help with filing IRS tax returns for our small but growing Texas-based software development company. Upon review of our accounting and tax records, Mr. Lin discovered that our first couple of years of business tax returns were filed with errors, so he corrected the errors, and filed an explanation notice with the IRS to reduce or eliminate our fines/penalties. We are very pleased with his support.
