Page Limit

Original submission: 20 pages using the 7x10 ACM Submission Format. The 20 pages includes text, figures, but no references. This is a strict limit for the initial submission.

Revised versions of the manuscript : 25 pages, including references.

Final version: Under no circumstances, ACM TACO will publish a paper that is longer than 25 pages. There is no option to buy additional pages.

Manuscript Type

Original work: this is manuscript which has never been published before in any form. A footnote needs to be added to the first page of the submission with the label New Paper, Not an Extension of a Conference Paper.

Conference extension: this is a manuscript which extends a previously published conference paper. At submission time, the conference paper should be accepted, and preferably be published too. A footnote needs to be added to the first page of the submission with the label Extension of Conference Paper. The rest of the footnote needs to cite the conference papers and state how this submission adds 30% new material over the prior conference paper(s). 

It is difficult to formally define "30% new material" but the following guidelines might help:
- adding 30% more pages to an existing manuscript is not enough if these pages do not contain new insights that were not mentioned in the original paper.
- evaluating a technique on more benchmarks is not enough if this evaluation just confirms the findings of the original paper.
- giving more details on a particular implementation is not enough if this information does not lead to additional insights or conclusions. It is better to add such information as auxiliary material to the original paper in the digital library.

An accepted ACM TACO paper should in any case contain a sufficient number of new insights that make the paper worth reading and citing. Otherwise, there is no point in publishing it.


During the manuscript submission process, you have to upload the PDF of the manuscript. Please check whether the PDF is uploaded correctly by downloading the manuscript after submission and checking whether it still displays correctly. For conference extensions, you have to upload all the conference papers the manuscript is an extension of (name them with the conference acronym and the publication year). You can add additional files that might help the associate editor and reviews to evaluate the manuscript.


ACM TACO submissions should contain original material that has not been previously published in a journal, nor is currently under review by another conference or journal. Please also check the ACM Author Representations Policy.

For conference extensions, the manuscript must contain at least 30% new material. This is a legal requirement to avoid copyright infringement. The authors have to convince the associate editor and the reviewers that the manuscript fulfills this requirement. A manuscript that does not comply with this requirement, cannot be published an ACM TACO. In case of doubt, the manuscript will be rejected.

List of conflicts

During the submission process you will be prompted to add a Cover Letter. In this box, list (one per line)

  • - all of the TACO Associate Editors an author on the submission may have a conflict with,
  • - all collaborators and their affiliations (for all authors on the paper) in the past 5 years, and
  • - the name of the universities and industry sites the author's graduated from/are affiliated with and the name of the author's adviser.

Revised Manuscripts

A revised submission should include responses to the reviewers comments. This has to be uploaded as text in the box provided otherwise the reviewers will not see your comments. A good format for the response is to list for each reviewer a summary of each comment followed by your response.


We strive to notify the authors within two months of submission. The ACM TACO review process is finite. There can be at most three rounds.

The first review round can lead to one out of four decisions: Accept, Minor Revision, Major Revision, Reject

The second review round (after Major Revision, Minor Revision) can lead to one out of three decision: Accept, Minor Revision, Reject. There is no possibility to get a second major revision; authors get only one chance to convince the reviewers to (conditionally) accept the manuscript.

The third review round (after Minor Revision) can only lead to either Accept or Reject.

Authors get three months to prepare a Major Revision, and one month to prepare a Minor Revision.

Hence, the total review process can maximally take 2+3+2+1+2=10 months. In practice, the average duration is around 6 months.

After acceptance of the paper, the authors get two weeks to submit the final version, which is forwarded to the production team. After copy-editing, the final version of the paper is uploaded in the digital library. In practice, it takes about 2 months between acceptance and publication in the digital library, bringing the total turnaround between submission and publication to at most 12 months. In January, April, July, October all papers uploaded in the digital library during the previous quarter are printed and mailed to the print subscribers.

Final Version of Manuscript

ACM TACO is using authoring templates found at  

When submitting the final version, you have to include

  • Name and address of contact author, including email address and phone number.
  • PDF of final version.
  • Figures in EPS or TIFF format.
  • Computing Classification Systems terms.
  • Additional keywords and phrases (
  • Please provide a brief description of your supplementary online-only material (i.e., text and multimedia material) to be published in the Digital Library. A short .readme.txt. file will appear in the DL along with your supplementary material describing its content and whatever requirements there are for using it.
