Tax Experts Serving Barber Valley

Castell Tax Experts provides tax preparation and bookkeeping for businesses in Barber Valley and throughout the Boise area. Our team is made up entirely of Enrolled Agents, which means we’re licensed by the federal government to represent you before the IRS. When tax issues get complicated, you’re not on your own.

We’re based in Nampa but serve clients across the Treasure Valley. Our focus is helping business owners keep more of what they earn through small business tax preparation that captures every legitimate deduction. Year-round support, not just during tax season.

Business Tax Preparation

Complete tax preparation for LLCs, S Corps, partnerships, and sole proprietors. We identify deductions most business owners miss and file returns that hold up to scrutiny.

Monthly Bookkeeping

Clean books that make tax time straightforward. Transaction categorization, bank reconciliation, and monthly financials so you always know where you stand.

IRS Representation

If the IRS sends a notice or starts an audit, we handle it. As Enrolled Agents, we’re authorized to represent you directly. You don’t sit on hold with the IRS or try to interpret letters yourself.

Tax Planning

Proactive strategy that reduces your tax bill before the year ends. Entity structure analysis, retirement contributions, and timing decisions that keep more money in your pocket.

Barber Valley Business Owners

Barber Valley sits in one of the fastest-growing parts of Boise. That growth creates opportunity for local business owners, but it also creates tax complexity. Real estate investors with rental properties. Contractors working new construction sites. Professionals running practices from home offices near the foothills.

We work with businesses doing $100K to several million in revenue. The ones that need real tax expertise but aren’t big enough for an in-house accountant. If you’ve outgrown TurboTax but don’t need a Fortune 500 firm, we’re built for that space.

Real Estate Professionals

Agents, investors, landlords, and property managers in Barber Valley and the surrounding Boise market. We handle real estate tax strategy including depreciation, 1031 exchanges, and rental income reporting.

Construction and Trades

General contractors, specialty trades, and home service companies working in southeast Boise’s growing neighborhoods. Job costing, equipment depreciation, and tax preparation that accounts for the way construction businesses actually operate.

Professional Services

Consultants, attorneys, marketing agencies, and other professional service firms. We track profitability, manage quarterly estimates, and keep your books ready for year-end without the last-minute scramble.

Healthcare Practices

Medical offices, dental practices, therapists, and veterinarians serving the Barber Valley community. Insurance receivables, patient billing reconciliation, and the specific compliance requirements healthcare businesses face.
