Arizona has transformed from a copper-and-tourism economy into a technology and manufacturing hub. Metro Phoenix is now one of America's fastest-growing semiconductor centers, with TSMC's multibillion-dollar fabs and a long-standing Intel presence, alongside strong aerospace and defense, healthcare, and construction sectors. Tucson adds optics and defense, tourism remains huge — from the Grand Canyon to Scottsdale resorts — and the state's low costs continue to draw businesses and residents from California.
Arizona is one of the friendliest states for income tax: it levies a flat 2.5% individual income tax, the lowest flat rate in the country (as of 2026 — confirm the current rate before filing). Sales tax works differently here — Arizona's Transaction Privilege Tax (TPT) is technically a tax on the vendor's privilege of doing business, not a tax on the buyer, and businesses must hold a TPT license. The state rate is 5.6%, but county and city add-ons bring the combined average to roughly 8.4%, and some jurisdictions top 11%. Many Arizona cities also tax business activities the state does not, so knowing your local TPT obligations matters.
Seven core services designed for small businesses across every industry in Arizona — all delivered remotely, all handled by our team.
Your most important foundation. We categorize every transaction, reconcile your accounts, and deliver clean P&L and balance sheet reports every single month — so you always know exactly where your business stands.
Months or years behind? We clean it all up — systematically organizing your past transactions so you can get current and stay compliant.
Starting fresh or inheriting a mess? We connect all your accounts, configure your chart of accounts, and set everything up correctly from day one.
Every account, every month. We match your books to your bank statements and flag any discrepancies before they become problems.
P&L, balance sheets, and cash flow statements delivered monthly in a format you can actually read and act on.
We track what you owe and what's owed to you — keeping your cash flow picture clear and your vendor relationships clean.
We ensure your payroll expenses hit your books correctly every pay period — including local Arizona municipal withholding — working alongside your payroll processor to keep everything reconciled.

We're not a local firm that added remote services. We were built remote-first, which means our process, communication, and delivery are optimized for businesses that never need to meet in person.
Tides is based in Greenville, SC and serves clients across the country. We know Arizona's business climate cold — the Transaction Privilege Tax (TPT) on the seller's gross receipts, filed through AZTaxes.gov across state, county, and city rates, plus the flat 2.5% income tax (the lowest in the nation) — and the industries that drive Phoenix, Tucson, and the high country.
No hourly billing surprises. You pay one flat rate each month based on your transaction volume — and you always know exactly what you're getting.
We don't just hand you a spreadsheet. We deliver clean, readable financial reports each month with plain-language summaries so you can make decisions — not just file paperwork.
Your CPA will thank you. Our books are consistently maintained at a level that makes tax season — federal, state, and local — faster, cheaper, and less stressful for everyone involved.
We earn your business every month. There are no lock-in agreements — just great service that makes you want to stay. Cancel anytime if it's not working.
