What happens if I forgot to collect sales tax from customers?

You still owe it. The state expects sales tax on taxable transactions whether you collected it from customers or not. When you forget to collect, the business absorbs that amount out of what would have been profit.

Going back to customers to collect after the fact usually isn’t realistic. For small retail purchases, it’s impossible. You’re not going to track down someone who bought a $40 item six months ago. For larger invoiced jobs, it’s awkward and may damage relationships. Most businesses treat uncollected sales tax as a lesson learned and focus on fixing the process going forward.

Your first step is calculating what you owe. Look at your taxable sales for the affected periods and multiply by the applicable rate. In Virginia, that’s typically 5.3%, though some areas in the Richmond region have slightly higher local rates. If you’ve been missing collection for multiple months, add up the totals for each period.

If you’re already registered for sales tax, you’ll need to file amended returns for the affected periods. Pay what you owe plus any interest and penalties. Virginia charges interest on late payments and may assess penalties depending on how late the filing is and whether you come forward on your own or they discover the issue first.

If you never registered at all, the situation is more complicated. Virginia offers a voluntary disclosure agreement program that can reduce penalties for businesses that come forward before an audit finds them. This is usually worth pursuing if you’ve been operating without collecting sales tax for an extended time.

Going forward, make sure your point of sale system or invoicing software charges sales tax automatically. Don’t rely on remembering to add it manually. If you’re not sure which products or services require sales tax in Virginia, get that clarified now. Some things are exempt, but most tangible goods are not.

The financial hit hurts, but it’s usually manageable if you catch it within a few months. The businesses that end up in serious trouble are the ones that ignore the problem for years and then face a state audit with back taxes, penalties, and interest compounding.

If your books are disorganized and you’re not sure how to calculate what you owe, getting help makes sense. A firm that handles sales tax services can sort through your records and figure out the actual liability. Getting the numbers right before you file matters because amending already-amended returns just complicates things further. If you need bookkeeping services in Richmond to clean up the records first, that’s often the right starting point before tackling the sales tax piece.
