I calculated the 2016 total consulting income I made, and paid 2016 taxes on all of it. I forgot the last month was paid in January, 2017. I got a 2017 1099 MISC for the Dec 2016 work.
How do I fix this? I assume I have to do the following:
1) Re-state my 2016 consulting income and re-submit a revised 2016 Income Tax form
2) Wait for IRS to accept the revision and send me the over-payment check in the mail
3) Pay the 2017 self employment and income tax on that revenue
4) Hope the amount are roughly the same
Anything else I missed?
