Don't worry, the page is almost loaded. We're untangling some sales tax spaghetti behind the scenes.
Overpayment Recovery

Every other page on this site is about what you owe. This one is about what you’re owed.

Businesses overpay sales and use tax constantly — on exempt purchases a vendor taxed anyway, on manufacturing equipment that qualified for relief nobody claimed, on tax charged in a jurisdiction that had no right to it. We find it, document it, and file to get it back.

Where overpayments come from

Nobody audits in your favor.

Under-collect and a state eventually comes looking. Over-pay and nothing happens at all — no notice, no flag, no correction. The money simply stays where it landed.

Which means the only way it comes back is if someone goes looking, and the only person with an incentive to look is you.

There is a deadline. Refund claims sit inside a statute of limitations — commonly three to four years, depending on the state. Every month you wait, the oldest recoverable quarter drops off the back.

Illustrative extract from a recovery review. Not every finding survives to a paid refund — the report distinguishes what’s clean from what’s arguable.
What we look for

Six places the money usually is.

None of these are exotic. They’re the ordinary consequences of a vendor applying a default, a tax engine applying a rule too broadly, or an exemption that required someone to know it existed.

Exemptions nobody claimed

Manufacturing equipment, research and development, agricultural inputs, pollution control, data center investment. Most states offer them, most require you to assert them, and most businesses that qualify never do.

Vendors taxing exempt purchases

A supplier charges tax because their system charges tax. If you bought for resale, or bought something exempt in that state, you paid something you never owed — usually across years of invoices.

The wrong jurisdiction’s rate

A city rate applied to an address outside the city, or a district tax charged where the district doesn’t reach. Small per transaction, large across a few hundred thousand of them.

Your own engine over-collecting

If your automation is mapped to tax something that’s exempt where you sell it, you’ve been charging customers tax they didn’t owe and remitting it. That’s recoverable — and it’s also class-action exposure until you fix it.

Use tax accrued twice

An invoice where the vendor already charged tax, self-assessed again by an accrual process that didn’t check. Common, invisible, and straightforward to document once found.

Freight, install, and services

Separately stated shipping is exempt in some states and not others. Installation labor, repair labor, and maintenance contracts all have their own rules. Vendors tend to tax all of it, everywhere.

How recovery runs

We do the digging, and we file the claim.

Finding the overpayment is the easier half. Getting a state to actually pay a refund is a documented, argued claim with its own procedure, its own deadlines, and its own reviewer — and states are considerably less enthusiastic about writing cheques than cashing them.

We file it, support it, and answer the questions that come back. Where the overpayment went to a vendor rather than a state, we pursue it through the vendor instead.

Scoped per engagement
Five stages
01
Scope the open period
Which states, and how far back each one’s statute of limitations still reaches. This defines the whole opportunity, and it shrinks every quarter.
02
Review the transactions
Accounts payable, fixed assets, use tax accruals, and your own sales where the engine may have over-collected. Accountants reading invoices against each state’s rules.
03
Build the claim
Schedules, invoice-level support, and the statutory basis for every line. A refund claim that isn’t documented to that standard gets denied on procedure rather than merit.
04
File and defend it
We submit to the state or pursue the vendor, then handle the review — including the questions, the requests for more support, and the appeal if a claim is denied for the wrong reason.
05
Fix the cause
A refund recovers the past. If a vendor keeps taxing exempt purchases, or your engine keeps over-collecting, you’ll be back in three years. We correct the setup and give your vendors the certificates they need.

Tick what applies. Each one is a pattern we’ve recovered against before — the more that are true, the more likely a review pays for itself.

Tick anything that applies. Most businesses recognise at least two or three of these once they think about the invoices rather than the returns.

Check for a refund

Indicative only. A real answer needs the invoices — but a first call will tell you quickly whether it’s worth pulling them.

Who goes and gets it

We do the digging.

Recovery work is invoice-level review — thousands of lines, looking for tax paid on things that were never taxable. It is unglamorous and it is where the money is.

We work it on contingency, so the only engagements we take are the ones we believe are worth your time.

Questions we hear a lot

Does filing a refund claim invite an audit?

It’s a fair concern and worth being direct about. A claim does get reviewed, and a reviewer looking at your records may notice other things. That’s exactly why we scope the whole picture first — if there’s exposure sitting next to the refund, you want to know before you file, not after. Sometimes the right advice is to fix the exposure first.

How far back can we go?

Typically three to four years, varying by state and measured from when the tax was paid. The practical consequence is that waiting costs you the oldest quarter every quarter.

What if we paid the tax to a vendor, not the state?

Then the claim usually runs through the vendor, who refunds you and reclaims it from the state. Some states allow a direct claim in certain circumstances. We work out which route applies and pursue it.

How is it priced?

Scoped per engagement once we’ve seen the likely size of the opportunity. If a first look suggests there isn’t enough there to justify the work, we’ll tell you that rather than bill you to find out.

The oldest quarter expires every quarter.

A first conversation costs nothing and tells you whether there’s a recovery worth pursuing. If there isn’t, we’ll say so plainly.
