I have a few clients that have called to tell me they received an IRS letter 6475. The issue is that the amount on the letters do not match what was actually deposited into their accounts. The letters are stating they received the full amount when they did not and in some cases it is staying they received less then what they actually received. Some of this clients I have already submitted their returns, They provided me proof of their 3rd stimulus payments. I am at a loss of what to do... Should I amend? should I let the IRS amend? Should I wait for a letter from the IRS saying they made changes and appeal? Any advice would be nice.
