Sales Tax Services in Irvine, CA - Clear Filing, Fewer Surprises
We help Irvine and Orange County business owners file correctly, fix gaps, and stay ahead of sales tax issues before they drain cash.

Catch Sales Tax Issues Early & Avoid Costly Mistakes
Sales tax services do more than file returns. We believe they should help you catch exposure early, stay on top of deadlines, and protect your business from mistakes that lead to notices, penalties, and unnecessary stress.
At Tehrani & Velez, LLP, we see every day how sales and use tax errors can create risk and affect the broader tax picture of a business.
If you sell products, operate across multiple locations, run e-commerce channels, or move goods and services between related entities, sales tax can become complicated quickly. We often work with business owners who are unsure where their weak spots are - until a deadline passes or a notice arrives. Missed filings, incorrect rates, or incomplete exemption records can quietly add up.
When sales tax starts slipping, it rarely stays contained. We’ve seen how it pulls attention away from operations, impacts cash flow, and creates pressure across your entire business. Sales tax isn’t isolated - it connects to your accounting, reporting, and income taxes. That’s why we take a more complete, practical approach to managing it.

Why Professional Sales Tax Help Matters for Irvine Businesses
We understand that every business in Irvine faces different sales tax challenges.
Retail and e-commerce companies may be managing inventory, resale certificates, and frequent filings.
Restaurants and hospitality groups often need clean POS data that aligns with reporting. Businesses with multiple entities can run into tax complications even when transactions stay internal.
Because we work closely with a wide range of industries, we don’t offer one-size-fits-all solutions. We look at how your business actually runs and tailor our guidance to fit your day-to-day operations.
