Bookkeeping & Tax Services for Columbia Village Businesses

Bookkeeping and tax services for Columbia Village businesses in Boise. Clean books, tax preparation, and Enrolled Agent expertise from Castell Tax Experts.

Bookkeeping & Tax Services

Castell Tax Experts provides Boise bookkeeping services and tax preparation for small businesses in Columbia Village and throughout the Treasure Valley. Monthly bookkeeping, financial statements, tax planning, and year-end filing. The financial support you need without hiring someone full-time.

We’re based in Nampa but serve clients across Boise, including neighborhoods like Columbia Village in southwest Boise. Everything happens digitally, which makes working together straightforward regardless of where you’re located.

Monthly Bookkeeping

Transaction categorization, bank reconciliations, and monthly closes. Your books stay current every month with financial statements that show where your business actually stands.

Business Tax Preparation

Tax preparation for LLCs, S Corps, partnerships, and sole proprietors. When the same team handles your books and your return, we catch deductions that outside preparers miss.

IRS Representation

Our team includes Enrolled Agents who are federally licensed to represent you before the IRS. If you get a notice or face an audit, we handle it directly instead of sending you to someone else.

Tax Planning

Year-round strategy instead of once-a-year scrambling. Quarterly estimates, entity structure decisions, and planning that keeps more money in your pocket.

Columbia Village Businesses We Work With

Columbia Village is a residential neighborhood, but plenty of business owners call it home. Contractors who run crews across the valley. Real estate agents working the southwest Boise market. Service providers, consultants, and professionals building practices. Many of them started doing their own books and taxes. Most have realized that’s not the best use of their time.

We work with established businesses typically doing $100K to several million in revenue. Big enough to benefit from professional financial support. Not so big that you need a full accounting department.

Contractors and Trades

Construction and trades businesses working across the Treasure Valley. Job costing, progress billing, and the financial tracking that helps you bid accurately and stay profitable on every project.

Real Estate Professionals

Agents, brokers, property managers, and investors. Commission income creates uneven cash flow. We track it properly and plan around the ups and downs so tax season doesn’t catch you off guard.

Professional Services

Consultants, attorneys, marketing professionals, and other service providers. Clean books that show profitability by client or project. Financial statements that support the growth you’re working toward.

New Businesses

First-year businesses getting set up correctly from the start. Entity selection, accounting system setup, and a financial foundation that scales with you instead of creating problems later.

Common Questions

You're based in Nampa. Do you work with Columbia Village businesses?

Yes. We serve businesses throughout the Treasure Valley including Boise and its neighborhoods. Most of our work happens remotely, but we're just 20 minutes away when you need to meet in person.

What does monthly bookkeeping cost?

Starting at $195 per month based on your business's expense volume. We quote exact pricing after reviewing your situation. Unlimited questions are included.

What's the advantage of working with Enrolled Agents?

Enrolled Agents are federally licensed to represent you directly before the IRS. If you receive a notice or face an audit, we handle it. Most bookkeepers and many accountants can't do that.

My books are behind. Can you help?

Yes. We do cleanup work regularly. Whether you're a few months or a couple years behind, we get your books current and then keep them that way going forward.

Do you handle both bookkeeping and taxes?

Yes. That's actually the point. When the same team handles your books all year and prepares your return, nothing falls through the cracks. Your tax preparer already knows your business.
