Platform collection does not make the seller's state footprint disappear
Marketplace facilitator laws can require a marketplace to collect and remit sales tax on certain facilitated transactions. That can reduce the seller's collection work for those orders, but the seller may still have direct sales, registrations, income or franchise taxes, or reporting requirements in the same state.
Treat marketplace collection as one channel in the state tax map.
Reconcile gross marketplace activity
Use marketplace reports to separate sales, discounts, returns, marketplace-collected tax, seller-collected tax if any, fees, reserves, and payouts. Do not book the net payout as revenue.
Keep tax collected and remitted by the platform visible enough to explain differences between marketplace gross sales and the seller's own sales-tax liability.
Separate direct-channel obligations
A business selling through both its website and a marketplace can have different collection responsibilities by channel. Track sales by state and channel so direct taxable sales are not hidden by facilitator-collected marketplace activity.
Review whether marketplace sales count toward state economic thresholds under the applicable rules.
Use filing instructions for each state
Some states require marketplace sales to be reported even when the marketplace remits the tax, while others handle the reporting differently. Follow current state guidance or adviser instructions for each registered jurisdiction.
A channel-level reconciliation gives the tax preparer the data needed to make that filing decision.
Questions buyers usually ask
If a marketplace collects sales tax, does the seller have no sales-tax work?
Not necessarily. The seller can still have direct-channel collection, state registrations, reporting obligations, and reconciliation work.
How should marketplace-collected tax appear in bookkeeping?
It should be separated from seller revenue and the seller's own tax liabilities so gross sales, platform activity, and net payouts can reconcile.

The core federal rule is that a business expense generally needs to be ordinary and necessary, but timing, entity type, capitalization, personal use, and special limitations still matter. Here is a practical recordkeeping guide for common expense categories.
Business tax preparation works best when the provider starts from reconciled books, understands the entity and state footprint, has the right source documents, and clearly defines what happens before and after filing.
