New York Insurers Have to Tell You Why Your Bill Went Up. Starting August 24.

Insurance Law Section 2356 takes effect August 24. Over 10% and the explanation arrives unprompted with the bill. Under 10% and you have to ask, then they have 20 days. It covers auto and homes, and DFS says the reasons have to be specific.

If your New York auto or home policy renews after August 24 and the premium is up more than 10%, your insurer has to hand you the dollar amount and the specific reasons behind it. You don’t have to ask. It comes with the bill.

If the increase is 10% or less, you do have to ask. Then they have 20 days.

That’s Insurance Law Section 2356, passed in the state budget in May and effective August 24. The Department of Financial Services published its guidance for carriers ahead of the date, along with answers to the questions the industry sent in.

Two things in there are worth your time.

First, DFS isn’t leaving room for a form letter. The guidance says the primary rating factors must be “specific enough so that the insured understands what factor(s) are causing the rate increase,” and that an insurer listing one reason when there are three has to list all three. The law spells out what counts: your own claims history, policy changes like a new car or a new driver in the house, anticipated losses in your rating territory, and higher claim costs such as repairs and medical bills.

Second, the reach is wider than auto. Subsection (a) covers private passenger auto, motorcycles, motorhomes, and policies on residential property of four units or fewer. The request-an-explanation piece in subsection (b) goes further: commercial vehicles, condo master policies, businessowners policies, even your umbrella policy, because an umbrella covers a vehicle. Renters policies are out. So is general liability. Neither one covers the building.

One clause is funny. Section 2356(d) says an insurer that lowers your auto premium because of this year’s budget reforms has to notify you and state that the cut is due to the budget reforms. Albany wrote its own credit line into the statute.

Here’s what changes for you. For years, “why did my bill go up” got answered with “rates went up.” That’s not an argument you can have. “Anticipated losses in your territory rose, and you added a driver in March” is. Once a factor is named in writing, you can check whether it’s actually true, and you can carry it to a competitor and ask what they’d charge on the same facts.

Do this. If your renewal lands after August 24 and it’s up at all, look for the notice on the bill. If it jumped more than 10% and no explanation is attached, that’s a compliance failure, and DFS says it will monitor this through market conduct exams and data collection. If it’s up 10% or less, send the written request. The 20-day clock starts when you send it. Then pull three quotes on identical coverage and identical deductibles while you wait, because an explanation and a better price are two different things. Our auto insurance rankings and the insurance estimator are a place to start.

One caveat, so nobody reads this as more than it is. An explanation is not a refund, and nothing in Section 2356 caps what your carrier can charge you. The cap comes later. On November 27, insurers lose the ability to push through overall average rate increases of up to 5% without the Superintendent signing off first.

Until then, you get the reason. Make them write it down.

Frequently asked questions

What does New York Insurance Law Section 2356 require?

For renewals billed on or after August 24, 2026, an insurer must attach a notice giving the dollar amount of the increase and a written explanation, including the primary rating factors, whenever the premium rises more than 10% (not counting increases from added coverage). When the increase is 10% or less, the insurer must include a prominent notice telling you that you can request a written explanation, and it must answer within 20 days of your written request.

Which policies does Section 2356 cover?

Subsection (a) covers private passenger auto, motorcycles, motorhomes, and policies on residential property of no more than four dwelling units. Subsection (b), the request-an-explanation piece, reaches further: commercial and private passenger vehicles, condo master policies, businessowners policies, and umbrella policies, because an umbrella covers a motor vehicle. It does not apply to renters policies or general liability, since neither covers loss of or damage to real property.

Can the insurer send a vague answer like 'rates went up'?

DFS says no. Its guidance states the primary rating factors must be specific enough that the insured understands what is causing the increase, and that an insurer must list all of them when there are two or more. The law gives examples: individual claims history, policy changes such as a new vehicle or a new driver, anticipated losses in your rating territory, and higher claim settlement costs.

Does this cap how much my premium can go up?

No. Section 2356 is a disclosure law, not a rate cap. The prior approval change arrives separately on November 27, 2026, when insurers lose the ability to implement overall average rate increases of up to 5% on nonbusiness motor vehicle policies without the Superintendent's prior approval.
