Top 10 labels sorted by alphabetical order based on quality most and quantity next. 

ACT, Germany
Standouts this year from Emile Parisien and Janne Mark. 
Babel, England
Quiet year but the latest duo album from Raymond MacDonald and Marilyn Crispell saved the day.
Blue Note, USA
Standouts included a Wayne Shorter magnum opus and new direction for Kandace Springs.
ECM, Germany
The Jarrett standards album was superb as was the first Bro to be released. Both Jarrett and Bro have second albums due soon that promise much.
Edition, England
A pretty solid year all in all. Tim Garland for me had his best release and showed once again what a world class player he is evident however for ages.
Gearbox, England
One of the UK’s very best jazz top tier labels at the moment.  
Impulse, USA/France
An unheard Coltrane album, tick that box. Huge for the label. And Sons of Kemet were also tops on a label that Universal have brought back. The corporate grip on their branding is unfortunate however and so historic imprints mean less than they should although Blue Note suffers least in this regard.
Pi, USA
Great Steve Coleman live at the Vanguard album a big highlight. Pi I think are the best avant label in the world currently.
Whirlwind, England
Another solid year. Jeff Williams the pick of the bunch with his best album to date and Julian Siegel too scored mightily with Vista. 
Young Turks, England
Heaven and Earth by Kamasi Washington did not disappoint. In fact it is the best album that I have heard all year, I think preferring it even to The Epic.

The list is curated and arranged alphabetically. [In terms of ranking if you want that, ECM is first, Young Turks second, Blue Note third, Whirlwind fourth, Edition fifth, Gearbox sixth, ACT seventh, Pi eighth, Babel, ninth, and Impulse tenth.] 

Some labels have fallen off the marlbank radar entirely because they have become inactive or their roster has changed for the worse. Major labels are once again mostly not where the action is taking place. So, Sony label OKeh really dipped in quantity and activity this year while Nonesuch relied as they have done for years on the jazz front on a few big artists only in Brad Mehldau and Joshua Redman who both produced some superb work. 

Sunnyside did not grab me much this year, last year I was quite a fan, and needs a sharper focus in terms of where they are in terms of their A&R.

Biophilia were consistently excellent and nearly made the top 10. Check out their Maria Grand release. (Grand pictured above.)

Of the many avant labels Cleanfeed was OK but patchy and they have had better years in the recent past. Dare2, Dave Holland's label had a very good year shaped around Uncharted Territories which is after the Kamasi the album that I have enjoyed most so far this year. 

Spartacus in Scotland hardly registered on my listening while Stoney Lane impressed with their Sara Colman release most and in What We're Made Of achieved one of the best vocal jazz albums of the year.

Manchester’s Gondwana kept the spiritual flame burning but often what they are putting out is predictable.

Brownswood had a very quiet year and when it succeeded via over hyped compilations mainly seemed more brand conscious than ever.

Jellymould had a disappointing year and while Northern Irish label Lyte had an interesting Jean Toussaint release they certainly need new names on the roster as do their English counterpart Jellymould.

Re. Christine Allen’s label Basho the big question is will The Impossible Gentlemen record again? If so a new phase for Christine Allen's groundbreaking label might begin but the prospects are not at all clear.

Ubuntu did very well to release the best Martin Speake album that I have ever heard.

RareNoise kept the faith with World Service Project on the prog-jazz front. 

Teddy D did well in profile terms especially built around festival touring with their acclaimed Making Other Arrangements.

Skip in Germany hardly registered this year but they have an ace up their sleeve because of the Tingvall Trio back catalogue. Camjazz were pretty quiet in Italy and Ozella have released nothing of note. The good news is that labels are emerging all the time and artists can be more DIY than ever via Bandcamp.
