Sales Tax Filing Made Simple

Sales Tax Services

Sales tax is more than adding a percentage at checkout. Businesses must determine where they have filing obligations, identify what they sell that is taxable, register correctly, collect the right state and local rate, maintain supporting records, and file and pay on time.

Fiotax helps businesses manage sales tax from registration through ongoing filings, cleanup, and compliance support. We provide practical, CPA-led guidance for New York businesses, online sellers, service providers, retailers, contractors, restaurants, and growing companies operating across multiple states.

Schedule a consultation to get your sales tax process organized before penalties, notices, or missed filings become a bigger problem.

The Sales Tax Process

1. Sales Tax Exposure Review

We begin by learning how your business operates. Sales tax rules depend on your products or services, customer locations, business locations, sales channels, and transaction volume—not simply whether you are incorporated in a particular state.

During the review, Fiotax evaluates:

• The products, merchandise, digital goods, or services you sell
• Whether your sales may be taxable, exempt, or partially taxable
• Where your business has employees, offices, inventory, warehouses, events, or other physical presence
• Online sales through Shopify, Amazon, Etsy, WooCommerce, marketplaces, or direct website sales
• Sales shipped or delivered to customers in other states
• Whether your business has reached an out-of-state economic-nexus threshold
• Existing sales-tax registrations, returns, notices, or unpaid balances
• Whether you accept resale certificates or other exemption documentation

Goal: Identify where sales-tax obligations may exist and prioritize the actions needed to bring the business into compliance.

Important: Sales-tax treatment is highly fact-specific. A service may be taxable in one state and not taxable in another, while sales made through a marketplace may have different collection and reporting rules than sales made directly through your own website.

2. Taxability Analysis

Not every sale is treated the same way. Before registering or filing, we help determine which revenue streams may be subject to sales tax.

Fiotax reviews your sales activity and categorizes transactions, such as:

Type of sale - Examples - Why it matters

Tangible products

1. Retail merchandise, equipment, supplies, furniture, packaged goods

• These sales are commonly taxable, subject to applicable exemptions

Taxable services

1. Certain repair, installation, maintenance, information, and personal services

• Taxability varies by service type and state

Digital transactions

1. Digital products, downloads, SaaS, subscriptions, online access

• Rules vary significantly by state and product structure

Construction-related work

1. Capital improvements, repairs, materials, labor

• Proper classification and documentation are especially important

Food and hospitality

1. Prepared food, catering, admissions, lodging

• These industries often have special sales-tax rules

Wholesale or resale sales

1. Sales to resellers or exempt purchasers

• Valid exemption or resale certificates may be required

Marketplace sales

1. Amazon, Etsy, Walmart Marketplace, eBay, etc.

• The marketplace may collect tax, but reporting duties can still remain

We help you establish a practical framework for tracking taxable sales, exempt sales, marketplace-collected sales, and sales by jurisdiction.

3. Sales Tax Registration

Once a registration obligation is identified, Fiotax assists with the setup process and helps make sure the business registers under the correct legal entity and with the appropriate state tax authority.

For New York businesses making taxable sales, registration generally involves obtaining a Certificate of Authority before starting taxable sales. New York generally requires registration at least 20 days before a business begins making taxable sales, and registered vendors must file returns even for periods with no taxable sales.

Our registration support can include:

• Reviewing entity information, EIN, ownership, addresses, and business activity
• Identifying the appropriate state sales-tax registration
• Assisting with New York sales-tax Certificate of Authority registration
• Registering businesses in additional states when nexus exists
• Helping establish online access to state tax accounts
• Reviewing effective dates and assigned filing frequencies
• Organizing confirmation notices, credentials, and registration records
• Coordinating sales-tax registrations with your bookkeeping and e-commerce setup

For New York registration, businesses typically use New York Business Express and need a NY.gov Business account, the state’s application checklist, and business/responsible-person information.

4. Collection Setup and System Review

Registering is only the first step. Your point-of-sale system, invoicing software, bookkeeping platform, and e-commerce store must apply the correct sales-tax treatment going forward.

Fiotax helps review and improve your collection process, including:

• Sales-tax settings in accounting and payment systems
• Product and service tax categories
• Customer exemption handling
• State, county, city, and special district rate considerations
• Shipping, delivery, installation, and service-charge treatment
• Marketplace-facilitator reporting
• Shopify, WooCommerce, Amazon, Stripe, Square, QuickBooks, and similar platforms
• Separation of taxable sales, exempt sales, and sales tax collected
• Procedures for maintaining resale and exemption certificates

Example: A New York retailer may need to collect sales tax on a taxable product sale, but a qualifying resale transaction may be exempt if the business obtains and retains the appropriate resale documentation. The underlying sale, certificate, invoice, and customer information must be retained in the business’s records.

5. Recordkeeping and Monthly Reconciliation

Sales-tax returns are only as reliable as the records behind them. Many sales-tax problems arise because bookkeeping records, point-of-sale reports, bank deposits, marketplace reports, and filed returns do not agree.

Fiotax helps create a repeatable reconciliation process so your business can substantiate each filing.

Our monthly or periodic sales-tax reconciliation may include:

• Reconciling gross sales to books and bank activity
• Separating taxable, exempt, nontaxable, and marketplace-facilitated sales
• Comparing sales-tax liability accounts to amounts collected
• Reviewing refunds, discounts, returns, and chargebacks
• Reviewing sales by state and jurisdiction
• Checking exemption certificates and customer documentation
• Identifying missing, duplicate, or incorrectly taxed transactions
• Preparing return-ready sales-tax schedules
• Retaining organized support for future audits or state questions

New York requires registered vendors to keep accurate and complete records of sales and purchases, which may be requested by the Tax Department to support returns.

6. Sales Tax Return Preparation and Filing

Fiotax prepares and supports the timely filing of sales-and-use-tax returns based on the business’s assigned filing schedule and transaction activity.

Our filing services can include:

• Preparing monthly, quarterly, or annual sales-tax returns
• Preparing no-tax-due returns when a filing obligation remains
• Reporting taxable, nontaxable, exempt, and marketplace-collected sales properly
• Calculating sales and use tax due
• Reviewing available vendor credits or discounts where applicable
• Coordinating electronic payment of tax due
• Filing returns through state online portals
• Saving confirmations and filing support
• Monitoring upcoming filing deadlines
• Preparing amended returns when errors are discovered
• Filing final returns when a business stops making taxable sales or closes

New York permits online filing for monthly, quarterly, annual, no-tax-due, amended, and final sales-tax returns.[4]

7. Sales Tax Notices, Past-Due Returns, and Cleanup

If you have missed returns, received a state notice, collected sales tax without filing, or discovered an old registration that is still active, Fiotax can help you assess the issue and organize a response.

We can assist with:

• Reviewing notices from New York or other state tax agencies
• Identifying missing sales-tax returns
• Reconstructing sales data from accounting records, bank deposits, payment processors, and e-commerce platforms
• Preparing delinquent or amended returns
• Reconciling sales tax collected to tax reported
• Reviewing estimated assessments
• Assisting with account closures and final returns
• Evaluating voluntary-disclosure or compliance options where appropriate
• Communicating with tax agencies under appropriate authorization

An inactive business may still need to file returns until the account is properly closed. In New York, final sales-tax returns can be filed online.

8. Ongoing Sales Tax Support

Sales-tax compliance changes as your business grows. Hiring employees in another state, storing inventory with a marketplace, adding an online store, attending trade shows, selling into new states, or changing your services can create new obligations.

Fiotax provides ongoing support to help you stay organized as your operations evolve.

Ongoing services may include:

• Monthly, quarterly, or annual sales-tax return preparation
• Nexus monitoring for multistate sellers
• New-state registration support
• Periodic review of taxability and collection settings
• Sales-tax account maintenance
• Recordkeeping procedures and internal controls
• Coordination with your bookkeeper, payroll provider, attorney, and software vendors
• Assistance with agency notices and audits
• Support for business expansion, acquisition, or closing

Frequently Asked Questions

Do I need to register for sales tax in New York?

If you plan to make taxable sales of tangible personal property or taxable services in New York, registration is generally required before you begin business. New York requires a Certificate of Authority to collect sales tax, and the state generally instructs businesses to register at least 20 days before beginning taxable sales.

Do I have to file a return if I had no sales?

Usually, yes—if you have an active registration and are required to file for that period. New York specifically states that sales-tax returns must be filed on time even when there are no taxable sales.

I sell online. Does the marketplace handle everything?

Not always. Amazon, Etsy, Walmart Marketplace, and other marketplace facilitators may collect and remit sales tax on certain marketplace sales, but direct website sales, multistate registrations, account maintenance, reporting requirements, and your own records may still require attention.

Can sales tax apply to services?

Yes. Some services are taxable and some are not, depending on the nature of the service and the state involved. It is important to review the actual service being provided, how it is billed, whether products are included, and where the customer receives the benefit.

What happens if I collect sales tax but do not file?

Collected sales tax is generally not business income. It must be accounted for, reported, and remitted. Failing to file can lead to notices, estimated assessments, penalties, interest, and more complicated cleanup work. Early action usually gives you more options.

Can Fiotax help with multiple states?

Yes. Fiotax can help assess multi-state exposure, coordinate registrations, organize sales data, and manage the compliance process for businesses with sales-tax responsibilities in more than one jurisdiction and for all 50 states.
