Welcome! Thank you for your question.
The state of Michigan does not have a gift tax. There is a federal gift tax. Any gift over $14,000 annually requires a federal gift tax return to be filed (709). However, there is a federal lifetime gift tax exemption
of $5.120 million dollars. The gift that you give your brother over $14,000 in one year will reduce your $5.120 million dollar exemption
but you will not owe gift tax until your total gifts over $14,000 annually exceed the $5.120 million dollars in your lifetime.
Most people never even get close to this. So the short answer is that you will have to report the gift but you will not have to pay tax.
As for the advise of the accountant to wait. I am not sure exactly what the account would have told you this. However, it is possible that you would wait to assure that any creditor that would owed money by your father had stepped forward to make a claim against any assets he owned upon death prior to distributing his money. If you can concerned about creditors you should check with your local probate court about publishing a notice to creditors without doing a formal probate. If your probate court will allow you to do this then the creditors will be out of luck after the notice to creditors time period expires. This will guarantee that the money is not subject to a future creditor claim.
