The Microsoft CSP price increase takes effect on 1 October 2026, adding 5% to annual-term software subscriptions that are billed monthly. It covers SQL Server, Windows Server, Client Access Licenses and System Center. Annual upfront billing and month-to-month subscriptions are unchanged, and existing subscriptions move to the new price at renewal.
CSP is Microsoft’s Cloud Solution Provider programme, the indirect channel through which resellers and distributors sell Microsoft licences to businesses. The change is a programme-wide one, so it reaches customers in every market where CSP operates, though the cash amount depends on local list prices and currency.
What Microsoft Said It Is Doing
Microsoft describes the change as a cost-of-capital uplift, meaning a charge for spreading payment across the year rather than taking it upfront. The announcement was published on 12 August 2026 in Microsoft’s Partner Center notices.
“Starting October 1, 2026, Microsoft applies a 5% cost of capital uplift for Cloud Solution Provider (CSP) software subscriptions (such as SQL Server, Windows Server, Client Access Licenses, and System Center) with annual-term commitments billed monthly,” the company wrote in its Partner Center announcement.
Microsoft’s stated reason is alignment: the update “aligns pricing treatment across sales channels while preserving monthly billing flexibility for customers.” The company also issued a correction, saying an earlier communication had carried the wrong effective date and that 1 October 2026 is the correct one.
Which Subscriptions Are in Scope
The uplift is defined by the combination of two things: an annual-term commitment and a monthly billing plan. Change either one and the subscription falls outside it.
| Commitment and billing | Affected by the 5% uplift |
|---|---|
| One-year term, billed monthly | Yes |
| One-year term, paid annually upfront | No |
| Month-to-month subscription | No |
| Three-year term, billed monthly or upfront | No |
The product list Microsoft gave is server-side licensing rather than desktop software: SQL Server, Windows Server, Client Access Licenses and System Center. Seat-based cloud products such as Microsoft 365 are sold on a different commercial model and are not part of this announcement.
When the Higher Price Reaches an Invoice
The date on the announcement is not the date most customers pay more. Two rules apply:
- New subscriptions: annual-term software subscriptions billed monthly that are bought on or after 1 October 2026 carry the uplifted price immediately.
- Existing subscriptions: the 5% takes effect at the first renewal falling on or after 1 October 2026, so a subscription renewing in, say, May 2027 keeps its current price until then.
Microsoft told partners that no system or Partner Center changes are required, and asked them to “communicate this update in advance to any customers with subscription renewals on or after October 1, 2026.” In practice that means the notice a business receives comes from its reseller, not from Microsoft directly.
What 5% Amounts To
On a monthly-billed annual subscription costing $1,000 over the term, the uplift adds $50, taking the cost to $1,050. That is the arithmetic the reseller channel has been working through. Work 365, a CSP billing software vendor, published the same worked example to show partners the margin they lose if they absorb the increase rather than pass it on.
Whether a given business sees the full 5% therefore depends on its reseller. Microsoft has raised the wholesale cost; what appears on a customer invoice is set by the partner’s own pricing. Microsoft’s list prices also vary by country and currency, so the same subscription does not cost the same everywhere.
Microsoft’s Other Dated Cost Changes This Year
This lands on business buyers in a year that already carried two others. Microsoft raised prices across most of the Microsoft 365 commercial suites from 1 July 2026, with the new pricing applying at the next renewal after that date to both annual and monthly billing plans, and covering Office 365 E3 and E5, Microsoft 365 E3 and E5, Business Basic and Business Standard, the F and G frontline and government tiers, Enterprise Mobility and Security, Windows E3 and E5 and Entra P1 and P2.
Separately, Windows 10 Extended Security Updates move into their second year in October, at $122 per device, or $183 for anyone who skipped Year 1, and Microsoft 365 Copilot Business now carries a $10 default usage limit.
Where the Detail Is Published
Microsoft points customers and partners to a dedicated frequently asked questions document covering which subscriptions are affected and how the uplift is applied, linked from the Partner Center announcement. The Partner Center announcements pages themselves remain the authoritative record of the effective date, which matters here because Microsoft has already corrected it once.
Frequently Asked Questions
When Does the Microsoft CSP Price Increase Start?
1 October 2026. New annual-term CSP software subscriptions billed monthly carry the higher price from that date; existing ones change at their first renewal on or after it.
How Big Is the Increase?
5%, which Microsoft calls a cost-of-capital uplift. On a subscription costing $1,000 across the annual term, that is an extra $50 before any reseller markup.
Which Products Does It Cover?
Microsoft named SQL Server, Windows Server, Client Access Licenses and System Center. It applies to annual-term commitments billed monthly through the Cloud Solution Provider programme.
Is Microsoft 365 Affected by This Change?
No. Seat-based cloud subscriptions such as Microsoft 365 are outside this announcement. Microsoft made a separate set of Microsoft 365 price changes effective 1 July 2026, applying at the next renewal after that date.
Does Annual Upfront Billing Avoid the 5%?
Microsoft states there is no change to annual billing or to month-to-month subscriptions; the uplift applies only to annual-term commitments billed monthly. Three-year agreements are also outside it. Terms available to a given business depend on its reseller agreement.
