The Missouri Employer Payroll Tax Calculator totals the taxes you owe as an employer for each Missouri worker. On top of wages you pay the employer half of FICA (6.2% Social Security + 1.45% Medicare), federal FUTA at an effective 0.6%, and Missouri SUI on the first $10,000 of wages.
How it works
Each tax has its own wage base, so the burden flattens as wages rise:
social security = min(wages, $168,600) x 6.2%
medicare = wages x 1.45%
FUTA = min(wages, $7,000) x 0.6%
MO SUI = min(wages, $10,000) x your experience rate
total employer tax = SS + Medicare + FUTA + SUI
fully loaded cost = wages + total employer tax
FUTA and SUI cap out quickly — at $42 and a few hundred dollars respectively — so for higher salaries the employer burden is dominated by Social Security and Medicare.
Example and notes
A $50,000 employee at the new-employer SUI rate of 2.376%:
social security: 50,000 x 6.2% = $3,100
medicare: 50,000 x 1.45% = $725
FUTA: 7,000 x 0.6% = $42
MO SUI: 10,000 x 2.376% = $237.60
total: ~$4,105 (about 8.2% on top of wages)
- FUTA assumes the full 5.4% state credit (net 0.6%); credit-reduction states differ.
- Your real SUI rate is assigned by Missouri based on your experience.
- Missouri has no employer SDI or PFML tax.
