About ITR Accounting and Tax Solution

Working from Phoenix, Arizona, ITR Accounting and Tax Solutions provides tax and accounting services to business owners, entrepreneurs and independent professionals. Appointments are available in person or virtually, and the firm works with companies of all sizes.

Monthly bookkeeping as an outside accounting department

Bookkeeping is handled remotely each month, so a small business can outsource its accounts in place of hiring an in-house bookkeeper. The firm describes this as acting like an outside accounting department, keeping records accurate so that the owner avoids the mistakes on a return that can lead to an audit. QuickBooks work and corporate accounting support are part of the accounting service.

Tax planning across the whole year

Tax planning is offered all year rather than only at filing time. The firm estimates a client's liability, plans quarterly payments and builds strategies for the year ahead, with the aim of taking every deduction the client is entitled to. Federal, state and local returns are all prepared.

Tax resolution for IRS and state matters

When a client receives a notice from the IRS, or has a problem with state or sales tax authorities, the firm steps in to help resolve it. Its tax resolution specialists handle these matters, and the firm works efficiently and discreetly. Its wider services include international tax support, multi-entity planning, and accounting for medical practices and beauty salons.

Business consulting in Phoenix and Scottsdale

The firm serves clients in Scottsdale and Phoenix, and it advises start-ups on their finances, their operations and how to plan for profit. It helps owners make sure their accounting system reflects their true financial position, so they can concentrate on running the business. Clients also have access to a learning center and a monthly tax tips mailing list between appointments.
