Tax Manager

We are looking for an experienced Tax Manager to support a focused indirect-tax compliance initiative. This temporary contract role will lead Washington sales and use tax work while assisting with filings and related requirements in other states as needed. The right person will be comfortable working independently, gathering and analyzing data from multiple sources, developing defensible allocation methodologies, and translating those methodologies into accurate tax calculations, filings, and vendor documentation.

Manage Washington sales and use tax compliance activities, along with filings in other states as needed. Calculate and file use tax on a monthly basis, ensuring submissions are accurate, timely, and supported by appropriate documentation.

Partner with Finance and other internal stakeholders to obtain, validate, and organize the data populations needed for tax calculations and filings. Identify gaps or inconsistencies and work through them independently.

Build practical, well-supported methodologies for allocating the use of benefits and services provided by vendors across relevant jurisdictions. Apply those methodologies to determine certificate distribution and use tax obligations.

Identify applicable vendors and prepare and distribute the appropriate tax certificates. Maintain clear records supporting certificate decisions, allocation methods, and filing positions.

Document calculations, assumptions, allocation methods, and filing procedures so the work can be reviewed, repeated, and maintained by the Finance team. Recommend process or control improvements that increase accuracy and efficiency.

Work closely with Finance leadership and accounts payable stakeholders to address questions related to vendor transactions, taxability, sourcing, and use tax treatment. Communicate complex tax considerations in a clear, practical way.

Strong hands-on experience with U.S. sales and use tax compliance, including preparing calculations and filing returns.

Deep knowledge of Washington sales and use tax requirements.

Experience supporting multistate sales and use tax compliance and researching state-specific tax treatment.

Demonstrated ability to develop and document defensible allocation or sourcing methodologies.

Experience reviewing vendor transactions and determining appropriate sales or use tax treatment.

Familiarity with exemption, resale, or other vendor tax certificates and the documentation required to support them.

Strong analytical skills and comfort working with large or incomplete data sets.

Advanced Excel or Google Sheets skills.

Excellent attention to detail, organization, and documentation practices.

Ability to work independently in an evolving environment with limited existing processes.

Clear communication skills and the ability to partner effectively with Finance and accounts payable teams.

Bachelor's degree in Accounting, Finance, Tax, or a related field preferred.

CPA, CMI, or other relevant tax credential is a plus but not required.
