If you use TaxCloud
You don’t need to chase every city rate update. Our platform automatically applies local changes — like Maricopa’s 0.50% increase on October 1 — so your checkout and filings stay accurate without the scramble.
Why it matters
- Compliance deadlines: Sellers must ensure rates are updated by October 1 to avoid under-collection or penalties
- Customer pricing: The increase may affect order totals for Maricopa buyers, which should be communicated clearly
- Multi-jurisdiction complexity: Local rate changes like this underscore the difficulty of keeping tax tables accurate without automation

- Update your tax tables and checkout systems before October 1
- Confirm POS and ecommerce platforms are applying the new Maricopa rate
- Consider sales tax automation with TaxCloud to handle ongoing local rate changes across Arizona and beyond
