TheAmericantaxsystemisahugemachinewithataxcodethatseemsmorecomplexthanrocketscience.Inthisarticle,wewilltakealookatthehistoryofincometaxesintheUnitedStates,examinetheprocessofindividualincometaxation.

TaxesinEarlyAmerica

TaxeshavealwaysleftasourtasteinthemouthofAmericancitizens.ThisnationalhatredfortaxesdateshacktothetaxburdenplacedontheAmericancoloniesbyGreatBritain.Colonistsweretaxedforeveryconsumergood,fromteaandtobaccotolegaldocuments.This"taxationwithoutrepresentation"ledtomanyrevolts,suchastheBostonTeaParty,inwhichcolonistsdumpedteaintotheBostonHarborratherthanpaythetaxonit.

AlthoughtheAmericancolonistsfoughtforindependencefromBritishruleandBritishtaxes,oncetheUnitedStatesgovernmentformed,itsmainsourceofrevenuewasderivedfromplacingcustomsandexcisetaxesonthesameitemsthatweretaxedbyGreatBritain.In1812,inanefforttosupportanexpensivewareffort,theU.S.governmentimposedthefirstsalestax,whichwasplacedongold,silverware,jewelryandwatches.In1817,internaltaxeswereterminatedandthegovernmentreliedontariffstosupportitself.Itwasn'tuntil1862thattheUnitedStatesimposedthefirstnationalincometax.

TosupporttheUnionArmy,Congresspassedtaxlawsinboth1861and1862.TheofficeofCommissionerofInternalRevenuewasestablishedbytheTaxActof1862,whichstatedthatthecommissionerwouldhavethepowertolevyandcollecttaxes.Theofficewasalsogiventheauthoritytoseizepropertyandincomeinordertoenforcethetaxlaws.Thesepowersremainprettymuchthesametoday,althoughtheInternalRevenueService(IRS)willtellyouthatenforcementtacticshavebeentoneddownabit.

TheFirstIncomeTax

In1863,thefederalgovernmentcollectedthefirstincometax.Thisgraduatedtaxwassimilartotheincometaxwepaytoday.Thosewhoearned$600to$10,000peryearpaidatarateof3percent.Ahigherratewaspaidbythosewhoearnedinexcessof$10,000.Aflat-ratetaxwasimposedin1867.Fiveyearslater,in1872,thenationalincometaxwasrepealed(撤销)altogether.

SpurnedonbythePopulistParty's1892campaign,CongresspassedtheIncomeTaxActof1894.Thisacttaxed2percentofpersonalincomethatwasmorethan$4,000,whichonlyaffectedwealthiestcitizens.Theincometaxwasshort-lived,astheU.S.SupremeCourtstruckitdownonlyayearafteritwasenacted.Thejusticeswrotethat,intheiropinion,theincometaxwasunconstitutionalbecause'itfailedtoabidebyaconstitutionalguideline.Thisguidelinerequiredthatanytaxlevieddirectlyonindividualsmustbeleviedinproportiontoastate'spopulation.
