Honestly, this is one of the most important things to check and most people never bother. Good that you caught it early.
Here's how to check right now:
**Check your CAS (Consolidated Account Statement)** — go to CAMS website (camsonline.com) or Karvy/KFintech site, request a CAS using your PAN and email. It'll show ALL your mutual fund holdings across all AMCs. Every fund entry will clearly say either 'Direct' or 'Regular' in the plan name. That's the simplest way.
Alternatively, log in to your AMC's website directly — say if you have HDFC Mutual Fund, go to hdfcfund.com, login with your folio number. The fund name itself will have 'Direct' or 'Regular' mentioned. If it just says 'Mirae Asset Large Cap Fund - Growth' without the word Direct, it's almost certainly a regular plan.
**Now about the damage** — this is where people underestimate the difference. Regular plans have higher expense ratios because the distributor (your RM/bank) gets a trail commission, usually 0.5% to 1% extra per year compared to direct. Sounds small. It's not. On ₹5 lakh over 20 years, that difference can easily be ₹3-5 lakh in corpus. Compounding works against you here.
**What most people get wrong** — they think switching from regular to direct will trigger tax. It will. Switching is treated as redemption, so you'll pay LTCG tax (10% above ₹1 lakh gains) or STCG (15%) depending on holding period. So don't switch blindly. If your gains are large, maybe wait, plan it across two financial years, or switch only fresh SIP investments to direct going forward.
**To invest direct going forward** — use MF Central (mfcentral.com), Coin by Zerodha, or go directly to the AMC website. Stop the regular plan SIPs and start fresh direct plan SIPs in the same funds.
Given you're 2 years in and probably have moderate gains, I'd say switch sooner rather than later. The longer you wait, the more you lose to commission. Do it before March end if you want to manage tax properly this year.
