Dynamic form Issue in Angular

Scenario :

A form is generated dynamically, I used this tutorial to create the form dynamically. When I click "Submit" button, the form value I get in the component is

ts :

  doSubmitICR(form) {
    console.log(form.value);

  }

form.value has the following values

{
 CaptainPoint:"0",
 Category:"restaurant",
 Description:"Test",
 DisplayDept:"kitchen",
 Group:"restaurant",
 GuestPoint:"0",
 ItemCode:"1",
 ItemName:"Test Item",
 PrintingDept:"frontoffice",
 SalesRate:"3",
 SubGroup:"restaurant",
 TAX1:true,
 TAX2:true,
 TabDisplay:"restaurant",
 Unit:"restaurant"
}

TAX1 and TAX2 are dynamic, those form controls were created from a tax table, If the table has TAX3 and TAX4, then instead of TAX1 and TAX2 in the above form, TAX3 and TAX4 form control is generated.

Issue :

  1. If the TAXs are dynamic, how can I pass these values to Web service say WebAPI2 as a model?
  2. Is it possible to filter only the TAX element from the form.value?

Any advice would be appreciated. Thank you.

The solution from alexKhymenko should work well. Alternatively, if the values you want to submit to the API will always have the format of TAX{d}, where d is some combination of digits, you could use the following to get just those values on a request object:

let request = {};
Object.keys(form.value).forEach(key => {
    if(/^TAX[\d]+$/.test(key)) 
        request[key] = form.value[key]
});
