But the investigation could also identify possible rule breaches in other areas, the Electoral Commission said.
The Electoral Commission said in a statement it would investigate whether Momentum "breached campaign finance rules in relation to spending".
Momentum is closely associated with left-wing Labour leader Jeremy Corbyn and has helped the party attract new voters, contributing to its unexpectedly strong performance at the June vote in which Conservative Prime Minister Theresa May lost her parliamentary majority.
Specifically, the watchdog will examine whether Momentum overspent during the election campaign and whether it returned payment and donation information which was either inaccurate or incomplete.
It said questions over compliance risked harming voter confidence.
"There is significant public interest in us investigating Momentum to establish the facts in this matter and whether there have been any offences".
Under the law, "non-party campaigners" who wish to undertake "targeted spending" - meant to influence people to vote for one particular registered political party or any of its candidates - have to to do so within prescribed spending limits.

Momentum played a major role in supporting the Labour Party in the June 8 general election, especially online, where it social media posts reached millions of people on Facebook and Twitter.
Momentum have been approached for comment.
The group has become notorious for trying to unseat Labour MPs who disagree with Mr Corbyn, and has recently asked the party's candidates to sign a pledge of loyalty to Momentum's aims in return for election funding.
