Sales tax records

# Sales tax records that don't add up

Whether you sell goods, services, online or in person, tax collected has to be tracked separately and reconciled to what was reported and paid. If it wasn't, we rebuild it from your sales records.

## What we rebuild

Sales by period and type, tax collected, tax reported and tax paid, reconciled so you can see where they differ.

## What we can't decide

Whether something is taxable, whether you have an obligation in another state, and how to resolve unreported periods are questions for the New Jersey Division of Taxation and your tax professional. We provide the numbers.

## Marketplace sales

If a marketplace collects tax for you, those sales need to be shown separately from sales you collect on yourself. We handle that split in the books.

## Start with where you sell

Sales tax depends on what you sell and where. In New Jersey the state rate is 6.625 percent, and some items and services are exempt, so rules vary by product. Sales outside the state may be taxed by other states if your sales cross their thresholds. A tax professional decides where you must collect.

## What we reconstruct

Taxable and non-taxable sales by period, tax collected and tax remitted, tied to your sales system and bank deposits. For each period you see what was reported, what the records show and the difference. Our [sales tax calculator](/bookkeeping/sales-tax-calculator) helps with simple checks on a price or total.

## What to prepare

Prior returns, your state registration, exports from your sales platforms, exemption certificates you collected, and a list of states you ship to. Do not guess missing numbers. Tell us what is unavailable.

FAQ

## Common questions

**Can you file my sales tax?**

Ask us what's possible for your situation. We'll be straight about what a bookkeeper can and can't do.

**Do I owe tax in other states?**

That's a question for a tax professional.

**Can you work from POS reports?**

Yes. Point-of-sale and processor reports are a common starting point.

Yes, but check each state's rules and thresholds with a tax professional.

**Do you file the returns?**

We prepare the reconciliation. Filing is up to you or your tax professional, and we can discuss our filing support.
