Yes. The federal Do Not Call rules cover sales calls to homes, and tax relief has no special exemption. You need a written do not call policy, trained callers and your own access to the national list, unless the person gave you written consent.
Every seller who calls needs its own registry account. For fiscal year 2026 the first 5 area codes are free, then $82 per area code, up to $22,626 for the whole country.
Calls to businesses are mostly outside the Telemarketing Sales Rule, but a sole owner’s cell phone may still count as a home line.
Some states keep their own lists too. This is a summary, not legal advice.
Updated October 2026. Market prices are list prices from public seller pages. Results depend on your firm. Not every lead becomes a case.
