Bakgrund: Revisionsplikten för små aktiebolag avskaffades i november 2010 i syfte attminska kostnader och förenkla administrationen för företagare. År 2017 fanns det cirka435 000 svenska aktiebolag som hade möjlighet att välja bort revision, varav enbart 85000 valde att bli reviderade. Inom området finns det mycket studier och därför anser vi attdet är intressant att studera vilka motiv som ligger till grund för valet av revision utifråntvå nya perspektiv. Syfte: Syftet med denna uppsats är att förklara valet av revision i aktiebolag utanrevisionsplikt utifrån ett perspektiv av motivkretsar där flera motiv samvarierar tillbeslutet av valet och utifrån ett dynamiskt perspektiv, i form av kedjor, som förklararbytet. Metod: Metoden är en tvärsnittsstudie som bygger på deduktiv ansats men med ettinduktivt inslag. Utifrån befintlig forskning och tidigare studier hittas olika motiv till attha eller inte ha revision, vilket är studiens deduktiva del. Eftersom varken motivkretsareller situationer som förklara bytet inte finns i befintlig teori eller forskning kan dessa intededuceras genom hypoteser och därav kommer de induceras. Slutsats: Studien finner indikation på att det går att finna motivkretsar där olika motivkan samvariera och att det kan finnas flera olika samtidiga motiv som ligger till grund förvalet av revision. Vidare finner även studien att ett byte av revision är något som sällansker, vilket kan ha sin förklaring i fenomenet stigberoende då bolag tenderar att sitta fast isitt initiala beslut. / Background: The audit obligation for small limited companies was abolished inNovember 2010 in order to reduce costs and simplify administration for entrepreneurs. In2017, there were approximately 435,000 Swedish limited companies that had theopportunity to opt out of auditing, of which only 85,000 chose to be audited. There are alot of studies in the area and therefore we consider it interesting to study the motives thatform the basis for the choice of audit from two new perspectives. Purpose: The purpose of this thesis is to explain the choice of audit in limited companieswithout audit obligation from a perspective of motive circles where several motivescovariate to the decision of the election and from a dynamic perspective, in the form ofchains, which explains the change. Method: The method is a cross-sectional study based on a deductive approach but withan inductive element. Based on existing research and previous studies, various motivesare found for having or not having an audit, which is the deductive part of the study. Sinceneither motive circles nor situations that explain the change do not exist in existing theoryor research, these can not be deduced by hypotheses and hence they will be induced. Conclusion: The study finds an indication that it is possible to find motive circles wheredifferent motives can covariate and that there may be several different simultaneousmotives that form the basis for the choice of revision. Furthermore, the study also findsthat a change of audit is something that rarely happens, which may have its explanation inthe phenomenon of step dependence as companies tend to be stuck in their initialdecision.
