Which tax-tables could be used for the FICA terms?

It depends. You may have to provide more clarity as to your question however some details are shown below.

1. FICA rate for wages is 6.2% for social security and 1.45% for medicare which is a total of 7.65%. Maximum social security wages for 2025 is $176,100.
2. Personal income tax rates change based on taxable income. Those rates can be viewed for 2025 using the link below.

Thank you so much for your help.

Is there a table number for his FICA tax return, if he has charity-donations and social-service expenses? 

For example, he often goes to a main-stream medical-center or church-service, and he pays for the transportation and medicine.

There is no FICA tax table it is just a flat 7.65% of the wages paid.  

Are you trying to assist with a W-4 for withholdings?  We may be able to offer a bit more information if you can provide some context.

Thanks for your response.

I checked online there might be "Form 843" for this FICA term.

Do we have some other tables or options?

Usually W-4 does not work for FICA taxes, right?

Does 529 Plans work for the FICA taxes?

Thank you again, SusanY1.
