Will my Sage 50 sales tax codes and rates convert correctly to QuickBooks?

Most Sage 50 sales tax codes and rates do convert to QuickBooks, but combined tax codes need careful mapping to sales tax groups and post-conversion verification.


In most cases, yes – Sage 50 sales tax codes and their associated rates carry over during a conversion to QuickBooks. The main thing to watch for is how single-rate and combined (multi-jurisdiction) tax codes map, because the two programs structure sales tax differently.

How single tax codes map

A single Sage 50 sales tax code – one agency, one rate – typically converts into a matching QuickBooks sales tax item with the same rate and agency name. The tax code name, the percentage, and the vendor (tax agency) it is paid to are the three fields our engineers look at first. If the agency name in Sage does not already exist in the QuickBooks file, it is created during the conversion.

How combined tax codes map

Sage 50 lets you build combined tax codes that bundle two or more jurisdictions – for example, a state portion and a local portion rolled into one code. QuickBooks handles this through sales tax groups, which are collections of individual sales tax items. During conversion, each component of a combined Sage tax code is usually mapped to its own QuickBooks sales tax item, and the combined code becomes a sales tax group containing those items.

What can get tricky is when the combined rate in Sage was set up as a flat percentage rather than as true components. In that situation, the conversion may bring it across as a single item at the blended rate rather than splitting it into parts. Whether that matters depends on how you report and remit tax to each jurisdiction.

What to verify after conversion

After the conversion is complete, we recommend checking three things:

Historical transactions that carried sales tax in Sage should also be spot-checked – pull a sales tax liability report for a prior period and compare the totals.

When something does not map cleanly

Occasionally a Sage 50 file has tax codes that are configured in a way QuickBooks does not have a direct equivalent for – for instance, tax codes tied to custom calculation methods or obsolete rate tables. Whether those convert cleanly depends on the specifics of your file. Rather than guess, we offer a free evaluation of your Sage 50 data so our engineers can tell you exactly what will carry over and flag anything that needs manual attention after the conversion.
