taxcalc.calcfunctions.EITCamount(basic_frac, phasein_rate, earnings, max_amount, phaseout_start, agi, phaseout_rate)[source]#

Returns EITC amount given specified parameters. English parameter names are used in this function because the EITC formula is not available on IRS forms or in IRS instructions; the extensive IRS EITC look-up table does not reveal the formula.

Parameters:

  • basic_frac (float) – Fraction of maximum earned income credit paid at zero earnings

  • phasein_rate (float) – Earned income credit phasein rate

  • earnings (float) – Earned income for filing unit

  • max_amount (float) – Maximum earned income credit

  • phaseout_start (float) – Earned income credit phaseout start AGI

  • agi (float) – Adjusted Gross Income (AGI)

  • phaseout_rate (float) – Earned income credit phaseout rate

Returns:

eitc – Earned Income Credit

Return type:

float
