State & Local Tax

Helping you navigate complex tax rules from state to state.

Nexus Determination & Filing Reviews

Explore Filing Options to Benefit Your Business.

Where are you filing? More importantly, where should you be filing, or are you paying too much tax in certain jurisdictions? We can review nexus using the latest standards, and review returns to ensure optimum filing methodologies. If you should be filing somewhere, but are not, we can help you with a voluntary disclosure that could significantly reduce tax liabilities, penalties and interest.

Economic Nexus

Should you file sales tax?

The U.S. Supreme Court decision in South Dakota v. Wayfair overturned the physical presence standard for sales and use tax nexus. Many states now impose nexus for sales and use tax collection for remote sellers that meet state thresholds for sales or number of transactions. We can help your business by reviewing your numbers to determine if you should be filing and collecting sales tax.

Sales Tax Filing

Complete your sales tax returns.
Is sales tax filing too taxing on your time and resources? We can streamline the process by working with top sales tax vendors to outsource your sales tax return filings and tax payments. We also offer a full line of sales tax compliance services, including exemption certificate management and sales tax audit defense.

Exemption Certificates

Keep track of your customers' exemptions.

States have become very strict on collecting and retaining exemption certificates from customers for sales, and issuing exemption certificates to vendors for purchases. We can help set up a system for collecting, validating, retaining and organizing your customers’ exemption certificates.

Sales Tax Refund Analysis

Find opportunities for tax refunds.
Are you paying too much sales tax? Many companies do without realizing it. We can help analyze purchase and accrual history to identify overpayments and refund opportunities.

Transactional Tax Planning

A proper plan can help you avoid tax issues.

Many business transactions present potentially significant direct and indirect tax issues. We can help identify and proactively plan for sales and use tax impacts of such transactions, including income, franchise and gross receipts tax, sales and use, employment and property taxes. Also, our buy-side and sell-side financial and tax due diligence services help you strengthen negotiations and make better-informed decisions.

Nexus and Voluntary Disclosures

Receive guidance on standards for sales and use tax.

Standards for sales and use tax nexus differ from other types of taxes. We can help identify where filing obligations exist, and mitigate liability through state voluntary disclosure (VDA) programs and tax amnesty programs.

Sales Tax Controversy

Prepare for audits and explore refunds.

Audit activity has increased for all types of state taxes. CSH SALT tax advisors can guide you through the examination process and explore opportunities for settlements and offsets in the form of refund requests where tax was overpaid. We actively work with state and local jurisdictions to effectively manage the audit and reduce the burden.
