Found that a machine shop client in Oklahoma City is paying state sales tax on their OG&E electric bill. Oklahoma exempts electricity used directly in manufacturing under Title 68 Section 1359.2. Filed Form 13-16-A with the Oklahoma Tax Commission and submitted the exemption certificate to OG&E. OG&E removed the tax starting with the next bill. OTC is processing the 3-year refund. Anyone know the typical processing time for Oklahoma refunds?
Oklahoma manufacturing exemption — filing with OTC is straightforward
Oklahoma Tax Commission refunds typically take 10-14 weeks in my experience. They're not the fastest but they're consistent. Make sure you included copies of every bill showing tax paid — if you submitted just a summary without the supporting bills they'll ask for them and that adds another 6-8 weeks. I also recommend filing the refund claim by certified mail so you have proof of the filing date. The 3-year lookback runs from the filing date, not the date the OTC processes the claim.
OTC processed the refund in 11 weeks — $14,200 covering 36 months. Steve was right about including the bill copies upfront. A colleague filed without them and got delayed 2 months waiting for the document request. Go-forward savings of about $390/month. Clean finding, clean process.
