I had to manually enter 1st quarter payroll because someone else doing it and all liabilities have been paid. I have successfully adjusted all liabilities with the exception of both company and employee social security and medicare. How can I adjust these?
I'm here to help and provide you some information concerning adjusting your federal taxes in QuickBooks.
Payroll wage and tax calculations in QuickBooks are derived from the payroll data and transactions you entered. The Medicare and Social Security has a fixed rate and cannot be adjusted, QuickBooks Online calculates federal withholding in compliance with IRS Publication 15 (Circular E), Employer's Tax Guide.
Though this would total the 941 taxes, the only tax that you may edit is the Federal Income Tax. For more details, you can check out this recommended article: Payroll 101.
